Solution

We can do the following operation_

17-50 = -33 ft

And that represent the distance between te heron and the squirrel

And since the actual height is -23 ft

Then the answer would be given by:

17 -(-23) = 40 ft

The distance from the squirrel and the bird is 40 ft

SOLUTION

The Point of a co-ordinate is always written as

Giving a point

For instance x=2 and y=2, the point will be

If the coordinate of x and y are reversed, the point will remain the same

Hence

the points with the same x- and y-coordinates will give the same location if the coordinate is reversed.

Therefore The Third option is correct (c)

we have the equation

x+8=14

step 1

subtract 8 both sides

x+8-8=14-8

x=6

therefore the answer is the last option

Perimeter = sum of outer lengths

Lenght of the triangle sides = 5ft

perimeter of a semicircle = π d; half = π d / 2

5 ft + 5ft + π r

5 + 5 + (3.14*3) = 19.42 ft

The standard deviation for a total of 200 games is 5.3735.

Let X = number of home runs of this player in 200 games played by him.

p = probability that a this player hits a home run in a single game and this is given to be 0.175.

Where np = Mean of X and √{np(1 - p)} is the standard deviation of X.

Here n = 200 and p = 0.175. So, the standard deviation for a total of 200 games is the standard deviation for a total of X

= √(200 x 0.175 x 0.825) / 2

= 5.3735

The value is 5.3735.

Multiplication of coefficients and variable

It's given the expression:

Answer:

[tex]\frac{5}{2}[/tex] or 2.5cm

Step-by-step explanation:

Hello! Let's help you with your question here!

Let's start by working out what we know and what we need. So, we know that P is a circle and Q is the shape of a quarter circle with a radius of 20cm. The area of Q is 9 times the area of P and we must find the radius of P.

To start, we're looking for area, so we should at least start looking at the area of a circle, given radius, which is:

[tex]A=\pi r^2[/tex]

Now, we don't necessarily know r (radius) and the area either. However, we can try to use the quarter circle as our guide for the full circle. So, we want to find the area of the quarter circle, we can do that by using this formula!

[tex]A=\frac{1}{4} \pi r^2[/tex]

The reason why we put a [tex]\frac{1}{4}[/tex] at the front of [tex]\pi r^{2}[/tex] is because we're only solving for a quarter of a circle instead of the entire circle.

Now that we have our formula! We can calculate the area of the quarter circle as follows:

[tex]A=\frac{1}{4}\pi 15^2[/tex]

[tex]A=\frac{\pi 15^2}{4}[/tex]   -We combine the fraction [tex]\frac{1}{4}[/tex] into the rest of the equation.

[tex]A=\frac{225\pi }{4}[/tex]   - Evaluating [tex]15^2[/tex]

Now that we have the area of the quarter circle, we can now work on the full circle. What we know is that the area of A is 9 times of B, since we're finding the radius of B, we can essentially plug in the area and solve for the radius of the full circle. That would be as such:

[tex]A=9\pi r^2[/tex]   -We're using the area of circle A to find the radius of B.

[tex]\frac{225\pi }{4} =9\pi r^2[/tex]   - Plugging in the area of the quarter circle.

[tex]\frac{225\pi }{4}/9\pi =\frac{9\pi r^2}{9\pi }[/tex]   - We divide [tex]9\pi[/tex] to get rid of it on the right side.

[tex]\frac{25}{4} =r^2[/tex] - When dividing by [tex]\pi[/tex], the numerator [tex]\pi[/tex] gets cancelled out.

[tex]\sqrt{\frac{25}{4} }=r[/tex]   -We square root to get rid of the squared.

[tex]\frac{5}{2}=r[/tex]    - Square rooted both numerator and denominator.

And there we have it! We finally get a radius of [tex]\frac{5}{2}[/tex] or 2.5cm.

Given the two sets:

we can write the product set of A and B in the following form:

next, we have that the number of elements in A is 2 and the number of elements in B is 3, then, we have:

finally, the equation that involves the numerals of the previous parts is:

where n(A) and n(B) represents the number of elements in A and B respectively.

Answer:

Step-by-step explanation:

The coterminal of angle with measure x is x + 360 degrees

Example:

If x = 30 degrees, then

The coterminal of x is 30 + 360 = 390 degrees

The coterminal of 128 degrees is 128 + 360 = 488 degrees

Then the answer is D

Answer:

a: a produces vertical stretch

b: b produces a horizontal stretch

h: h produces a translation to the left of the X-axis

k: k produces a translation on the new function upward of the Y-axis

Step-by-step explanation:

An intermediate function is produced by adding each variable in the following order:

1) f(x) to f(bx):

Effect:

the horizontal stretch of f(x) along the x-axis with stretch factor b

2) f(bx) to f(bx+h):

Effect:

translation of f(bx) to the left of the X-axis by h units

3) f(bx+h) to a*f(bx+h):

Effect:

vertical stretching of f(bx+h) by a factor equal to a

4) Finally, a*f(bx+h) to a*f(bx+h)+k:

Effect:

vertical translation of a*f(bx+h) by h units upwards along the Y-axis.

The symmetry of a quadratic equation is given by the line that passes through its vertex, so in order to find the axis of symmetry we need to find the coordinate of the vertex, which is done below.

Where "a" is the number multiplying the square factor and "b" is the number multiplying the factor that isn't squared. To find these two constants we need to expand the equation given.

We have that a = 1 and b = 4, therefore:

The axis of symmetry for this quadratic equation is x=-2.

I have 42 dimes in my piggy bank according to the given condition of 66 coins and amount $10.20 and used the system of equation as well as substitution method.

A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, also known as a system of equations or an equation system. A group of two or more equations that share the same variables is known as a system of equations. A set of values for a variable that simultaneously satisfy each equation is the solution to a system of equations.

Finding the value of any variable from one equation in terms of another variable is the first step in the substitution method. For instance, if there are two equations, x+y=7 and x-y=8, we can deduce that x=7-y from the first equation. Applying the substitution method begins with this.

Here,

x+y=66    ......(1)

1 dime values 10 cents.

1 quarter values 25 cents.

10x+25y=1020       ........(2)

x=66-y

10(66-y)+25y=1020

660-10y+25y=1020

15y=360

y=360/15

y=24

x=66-24

x=42

I used the system of equations and the substitution method to determine that I have 42 dime coins in my piggy bank in accordance with the requirement of 66 coins totaling $10.20.
