The ball thrown upwards hit the roof and returns back to the ground.The upward moment is given with : s= -t2+3t+4
and downward :s= - 2t2+t+7

How high is the roof from the ground ?

Answers

The height of the roof will be 10.75 units.

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is to find the height of the roof.

The upward motion is modelled by the equation -

S = - t² + 3t + 4

The height of the roof is equal to maximum height attained. For the maximum height attained -

dS/dt = 0

d/dt (- t² + 3t + 4) = 0

- 2t + 3 = 0

2t = 3

t = 3/2                                                    .... Eq(1)

The  height of the roof will be -

S(max) = - t² + 3t + 4

S(3/2) = - (3/2)² +(3 x 3/2) + 4

S(3/2) = 9/4 + 9/2 + 4

S(3/2) = 2.25 + 4.5 + 4

S(3/2) = 10.75 units.

Therefore, the height of the roof will be 10.75 units.

Step-by-step explanation:

"-":  because the slope is negative

"4/5": because its the slope

"x": because it is part of 'mx + b'

"1.8": because it's the y-intercept that fits this equation

Answer:

y = -4/5x + 1.8

Step-by-step explanation:

1st find the slope, m,  using these 2 points:  (-4,5) and (6,-3)

m = (-3-5) / (6--4) = -8/10 = -4/5

Now use the point (-4, 5) in the the point-slope form to find b:

y - 5 = -4/5(x - -4)

y - 5 = -4/5(x + 4)

y - 5 = -4/5x - 16/5

y = -4/5x -16/5 + 25/5 = -4/5x + 9/5

Now write the equation in slope-intercept form:

y = -4/5x + 1.8

WILL GIVE BRAINLIEST

Answers

Answer:

There are several lines of evidence that scientists use to determine the relative age of the Earth and its various features. These include:

Stratigraphy: This refers to the study of rock layers and the sequence in which they were formed. Scientists use stratigraphy to determine the relative ages of different rock layers and the fossils they contain. The principle of superposition states that in any undisturbed sequence of rocks, the oldest rock layers will be at the bottom and the youngest will be at the top.

Fossil record: Fossils are the remains of plants and animals that lived in the past. By studying the fossils in rock layers, scientists can determine the relative ages of different rock formations and the organisms that lived in them. Fossils of extinct species found in lower rock layers are older than those found in higher rock layers.

Radiometric dating: This is a method that uses the decay of radioactive isotopes in minerals to determine the absolute age of rocks and minerals. Scientists can use radiometric dating to determine the age of a rock or mineral, and by comparing the ages of different rocks and minerals, they can determine the relative ages of different rock formations and the Earth's surface features.

Using expression {River=x(race)} River's length is 7.38 times the race's length, approximately.

What are expressions?

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division. For example, x + y is an expression, where x and y are terms having an addition operator in between. In math, there are two types of expressions, numerical expressions - that contain only numbers; and algebraic expressions- that contain both numbers and variables.

e.g. A number is 6 more than half the other number, and the other number is x. This statement is written as x/2 + 6 in a mathematical expression. Mathematical expressions are used to solve complicated puzzles.

We know that

The river is 310 miles long.

The race is 42 miles long.

So, if we want to know know how many times as long as the race is the river, we just need to use this expression

River=x(race)

Where x represents the factor that expresses the ratio between both, solving for x we have

x=river/race=310/42≈7.38

Therefore,

The estimated force on the projectile when it is traveling at 750 ft/sec is approximately 696.7 lbs.

The Possible Interpolating Polynomial

One possible interpolating polynomial for these data points is a polynomial of degree 3, also known as a cubic polynomial. Using software or a calculator to fit a cubic polynomial to the data points, the resulting equation is:

F(v) = -0.00000016v³ + 0.0004v² - 0.08v + 0.4

A farmer has enough food to feed 20 animals in his cattle for 6 days. How long
would the food last if there were 10 more animals in his cattle?

Answers

Answer:

4 daysb

Step-by-step explanation:

Here the number of animals and the number of days are in inverse proportion. Hence the food will last 4 days.

The food will last for 6 days for 20 animals.

If there were 10 more animals in the cattle, the total number of animals would be 20+10 = 30.

The food will last for the same 6 days but now it would be divided among 30 animals.

Therefore, the food would last for 6 days / 30 animals = 0.2 days per animal.

So, the food will last for 0.2 days if there were 10 more animals in the farmer's cattle.

A bank loaned out $12,000, part of it at the rate of 6% per year and the rest at the rate of 16% per year. If the interest received totaled$1000, how much was loaned at 6%?

Answers

The amount loaned at 6% was $9200. The solution has been obtained by making and solving the equations.

What is an equation?

A claim that two expressions are equal and connected by the equals sign "=" is the mathematical definition of an equation. The two expressions need not be entirely composed of variables; one expression may have variables while the other may not.

We are given that a bank loaned out $12,000 and a part of it at the rate of 6% per year and the rest at the rate of 16% per year.

Let the amount loaned at 6% be 'x'

So, amount loaned at 16% will be '12,000 - x'

The total interest received was $1000.

Therefore,

⇒6%x + 16%(12000-x) = 1000

⇒0.06x + 1920 - 0.16x = 1000

⇒920 = 0.1x

9200 = x

Hence, the amount loaned at 6% was $9200.

How do i solve for value of m

Answers

Hi there!
From my best knowledge I assume this has to do with triangle angles and linear expressions.
All triangles add up to 180°, so we will use this formula with the triangle angels given.
(4m + 6) + (5m + 3) = 180°
9m + 9 = 180°
(Combined like terms) 4+5 & 6+3
9m = 171 (Subtract 9 from 180 = 171)
m = 19 (Divide 9 from 171)

So, m in the expression equals 19 but let’s double check.
(4(19) + 6) + (5(19) + 3) = 180
4 x 19 = 76 + 6 = 82°
(So that angle separately is 82 degrees.)
5 x 19 = 95 + 3 = 98°
(So that angle separately is 98 degrees.)
Add both angles - 82° + 98° = 180°
So it’s a true formula! Both angles in the triangle add to 180 as it should.
But as for the original question being asked, yes m = 19
= m = 19

The area of triangle, using the formula A is 146.9 in^2

How to find a area of triangle using trigonometry?

Trigonometry is a branch of mathematics that deals with the relationships between the angles and sides of triangles. It can be used to calculate the area of a triangle by using the length of its sides.

The most commonly used formula to calculate the area of a triangle is known as Heron's formula. This formula uses the lengths of the triangle's three sides, known as a, b, and c. Then use the formula A = 1/2 x[tex]\sqrt{(a + b+ c)(-a + b + c)(a - b + c)(a + b -c)}[/tex] to calculate the area of the triangle.

To calculate the area of a triangle using Heron's formula, first measure the length of each side of the triangle. Then use the lengths of the sides to calculate s using the formula above. Once you have calculated s, plug the values for a, b, and c into Heron's formula to calculate the area of the triangle.

A = 1/2ab⋅sin(C)

= 1/2(21 in. )(14 in.)⋅sin(88)

= 1/2(294 in.2 )⋅sin(88)

= 1/2(294 in.2 )⋅0.9945

a. Graph

Graph is plotted using online graphing tool. 2 points identified are (-4, 9) and (-3, 3)

b. Domain and Range

First let's understand what domain and range are

Definition of domain

The domain of a function, y = f(x),  is the set of input(x)  values for which the function is real and defined

The function has no undefined points nor domain constraints.  You can see that the graph goes to infinity for negative and positive x values Therefore,  the domain is :

[tex]-\infty \: < x < \infty \:[/tex]

which can be expressed in interval notation as:

[tex]\left(-\infty \:,\:\infty \:\right)[/tex]

Definition of range

The range of a function y = f(x) is the set of values for y over the domain for which the function is defined

As [tex]x \rightarrow \infty[/tex], [tex]y \rightarrow 1[/tex]

y never quite reaches 0 but its value approaches 1 and therefore the range is
[tex]f(x) > 1\\\\[/tex]

In interval notation:
[tex]\left(1,\:\infty \:\right)[/tex]

c. End Behavior

The end behavior of a function  f(x)  refers to how the function behaves when the variable x  increases or decreases without bound. In other words, the end behavior describes the ultimate trend in the graph of f(x) as [tex]x \rightarrow \pm \infty[/tex]

In this particular function we see that as [tex]x\to \:+\infty \:,\:f\left(x\right)\to \:1\\[/tex]

and as [tex]x\to \:-\infty \:,\:f\left(x\right)\to \:\infty\\[/tex]

d. Point (-3, 3)
By pure chance I chose this point as one of the points asked for in part a because I was looking for integer values I don't think it matters that there is repetition

(-3, 3) is plotted on the graph as point A

3. Evaluate f(-3)
We have
[tex]f(x) = 8\left(\dfrac{1}{4}\right)^{x+4}+1[/tex]

To find f(-3) substitute -3 for x in the above function:

[tex]f(-3) = 8\left(\dfrac{1}{4}\right)^{-3+4}+1\\\\= 8\left(\dfrac{1}{4}\right)^1} + 1\\\\\\= 8\left(\dfrac{1}{4}\right) + 1\\\\= 2 + 1 \\\\= 3[/tex]

So f(-3) = 3

Answer:

a)  See attachment 1.

b)  Domain: (-∞, ∞)

     Range: (1, ∞)

c)  As x → -∞, f(x) → ∞

    As x → ∞, f(x) → 1⁺

d)  See attachment 2.

e)  See below.

Step-by-step explanation:

Given exponential function:

[tex]f(x)=8\left(\dfrac{1}{4}\right)^{x+4}+1[/tex]

Part a

To find the y-intercept, input x = 0 and solve for y:

[tex]\implies f(0)=8\left(\dfrac{1}{4}\right)^{0+4}+1[/tex]

[tex]\implies f(0)=8\left(\dfrac{1}{4}\right)^{4}+1[/tex]

[tex]\implies f(0)=8\left(\dfrac{1}{256}\right)+1[/tex]

[tex]\implies f(0)=\dfrac{1}{32}+1[/tex]

[tex]\implies f(0)=\dfrac{33}{32}[/tex]

[tex]\implies f(0)=1.03125[/tex]

Therefore, the y-intercept is (0, 1.03125).

Substitute x = -2 into the function to find a second point on the curve:

[tex]\implies f(-2)=8\left(\dfrac{1}{4}\right)^{-2+4}+1[/tex]

[tex]\implies f(-2)=8\left(\dfrac{1}{4}\right)^{2}+1[/tex]

[tex]\implies f(-2)=8\left(\dfrac{1}{16}\right)+1[/tex]

[tex]\implies f(-2)=\dfrac{1}{2}+1[/tex]

[tex]\implies f(-2)=\dfrac{3}{2}[/tex]

[tex]\implies f(-2)=1.5[/tex]

Therefore, a second point on the curve is (-2, 1.5).

Part b

The domain of a function is the set of all possible input values (x-values).  

The domain of the given function is unrestricted:

Interval notation: (-∞, ∞)

The range of a function is the set of all possible output values (y-values).

As the exponential part of the function is always positive, the range of the given function is restricted:

Interval notation: (1, ∞)

Part c

As x approaches negative infinity, the function approaches positive infinity:

As x → -∞, f(x) → ∞

As x approaches positive infinity, the function approaches f(x) = 1.

As x → ∞, f(x) → 1⁺

Part d

See attachment 2.

Part e

Substitute x = -3 into the function:

[tex]\implies f(-3)=8\left(\dfrac{1}{4}\right)^{-3+4}+1[/tex]

[tex]\implies f(-3)=8\left(\dfrac{1}{4}\right)^{1}+1[/tex]

[tex]\implies f(-3)=8\left(\dfrac{1}{4}\right)+1[/tex]

[tex]\implies f(-3)=2+1[/tex]

[tex]\implies f(-3)=3[/tex]

The value 0.031 represents the interest rate, which means the annual compounded interest rate is 3.1%.
The value 0.031 represents the interest rate, which means the annual compounded interest rate is 0.31%.
The value 0.031 represents the investment period, which means the investment is invested for 0.031 years.
The value 0.031 represents the investment period, which means the investment is invested for 3.1 years

Answers

The quantity which represents the 0.031 in the given formula of compound interest, the value represents the annual compound interest rate 3.1%, So option A is correct

What is compound interest?

A loan or deposit amount is subject to compound interest as interest. In everyday life, it is the most prevalent idea. Both the principal and the interest accrued over time affect the compound interest for a given amount. Between compound and simple interest, this is the primary distinction.

[tex]A = P[1 + r/n]^{nt}[/tex]

Where,

A = compound interest

P = Principle Amount

r  =  Interest rate

n = number of period for which interest is calculated

t = time

Given that,

A equal to 2,400 plus quantity 1 plus 0.031 over 4 end quantity all raised to the power of 4 times t

[tex]A = 2400[1 + 0.031/4]^{4}[/tex]

So, here we can see that r is equal to 0.031

It represents the annual compound interest rate of the compound interest

Hence, it is a annual compound interest which has value of 3.1%
