To solve this problem, we will first find the standard form of the circle equation. Given a circle of radius r and center (h,k), the standard form of the circle equation would be

In our case, we have h=8 , k=6 and r=10. So the equation for the given circle would be

The general form of the circle equation can be obtained from expanding the squares on the left side of the equality sign. Recall that

So, applying this to the standard equation we get

So our equation becomes

Operating on the left side, we have

By subtracting 100 on both sides, we get

which the general form of the equation of the given circle.

Using a graphing tool, we have that the circle's graph would be

Answer:

b = -2

Step-by-step explanation:

y = mx + b;         (-2, 4)

y = -3x + b          (x₁, y₁)

m = -3

y - y₁ = m(x - x₁)

y - 4 = -3(x -( -2))

y - 4 = -3(x + 2)

y - 4 = -3x - 6

   +4           +4

------------------------

y = -3x - 2

An exponential function which is represented by the table above is: f(x) = 4(1/2)^x

An exponential function simply refers to a mathematical function whose values are generated by a constant that is raised to the power of the argument. Mathematically, an exponential function can be modeled by using this equation:

f(x) = abˣ

Where:

From the table above, we would calculate the value of a and b:

At x = 0 and y = 4; the value of a (initial value) is 4.

Rate of change, b = Δy/Δx

Rate of change, b = 1/2

Substituting the parameters into the formula, we have;

f(x) = abˣ

f(x) = 4(1/2)^x

Check:

f(x) = 4 × (1/2)^x             f(x) =  4 * ( 1/2 )^x

f(x) = 4 × (1/2)²               f(x) = 4 × (1/2)⁻²

f(x) = 4 × 1/4                  f(x)  = 4 × 4

f(x) = 1                            f(x)  = 16

We are asked to find the probability that a data value in a normal distribution is between a Z score of -1.52 and -0.34

From the Z-table, the probability corresponding to the Z-score -1.52 is 0.0643

From the Z-table, the probability corresponding to the Z-score -0.34 is 0.3669

So, the probability is

Option A is the correct answer.

step 1

we have that

44=(1/2)[180-arc} ------> by exterior angle

solve for arc

88=180-arc

arc=180-88

arc=92 degrees

give me a minute to draw a figure with letters to better understand the problem

we have that

x+?=180 degrees -------> by form a linear pair (supplemenatry angles)

x=arc=92 degrees ------> by central angle

so

?=180-92

?=88 degrees

therefore

The probability is given the following formula:

Probability = Favorable / total outcomes

In this case, there number of students that selected a forgetfull sperheroe that can fly is 6, the total number of outcomes is 6 + 11 + 5 + 7 = 29, then we get:

Probability = 6 / 29

Then, the probability of selecting a forgetful superheroe that can fly is 6/29

It shows that the lines are coincident.

The system has an infinite number of solutions. Also, point (3,0) is one of the solutions.

Answer:

∠ FAE = 120°

Step-by-step explanation:

4x and 2x are a linear pair and sum to 180° , that is

4x + 2x = 180

6x = 180 ( divide both sides by 6 )

x = 30

then

∠ FAE = 4x = 4 × 30 = 120°

Answer:

Explanations:

a) The scientific notation is generally expressed as;

A is any real numbers between 1 and 10

n is an integer

Given that the total surface area of North America is 9,540,000 square miles. This is expressed in scientific form as;

From the scientific notation, A = 9.54 and n = 6

b) Given the scientific notation as shown:

Writing in standard form means writing in the normal way we write numbers/decimals. Hence;

a)  2711/7576

b)  43

=================================================

Explanation:

a) 2711 are e-bikes and there are 3277+2711+1588 = 7576 total bikes. Divide the values to get 2711/7576 . This fraction cannot be reduced because the GCF of 2711 and 7576 is 1.

---------

b) There are 3277 bikes with fat tires out of 7576 total. Use a calculator to get 3277/7576 = 0.43255 approximately. This converts to 43.255% and then rounds to 43%

The percent sign is already typed in, so you just need to type in the whole number 43 for this box.

The volume and surface area of a rectangular prism are given by the formulas below

In our case,

Thus, the answers are: Surface area=848ft^2, and Volume=1428ft^3

There are several forms in which one can write the equation of a line. Have in mind that TWO variables should be included in the equation. These two variables are: x and y.

If you type the equation in a form that looks like:

A x + B y = C

where the A, B, and C are actual numbers (like for example: 3 x - 2 y = 5)

This is the standard form of a line. to recognize it notice that bith variables x an y appear in separate terms on the LEFT of the equal sign., and a pure number (no variables) appears on the right of the equal sign.

Another form of writing the equation of a line is in the so called "solpe-intercept" form. This form looks like:

y = m x + b

Notice that in this case the variable ÿ" appears isolated on the left , and on the right of the equal sign you get a term with the variable x, and another constant (pure number) term (b). Like for example in the case of:

y = 3 x

1) Firstly, let's find the composite function g(f(x)) plugging into the x variable in g(x) the function f(x):

2) To write that as the standard form, let's replace g(f(x)) with "y" and write the polynomial orderly to the greatest coefficient to the least one.

First let's calculate the slope of the straight line

For slopes that are perpendicular to each other we can use the following formula

Where

m1 = original slope

m2 = perpendicular slope

Now for the intersection

The equation of the line that passes through the point (-5,4) with a slope of -1/5 is

The height of the pole according to the attached image and parameters given is; 220 cm.

It follows from the task content that the height of the pole is to be determined from the parameters given.

From observation, the triangle formed by the situation is a right triangle.

Hence, the height of the pole can be determined by Pythagoras theorem; where, c² = a² + b².

Therefore, we have;

221² = 21² + p²

p² = 48,841 - 21²

p² = 48,400

p = √48,400

p = 220.

On this note, the height of the pole is; 220 cm.

The equation is:

Convert it to standard form:

Answer:

[tex]y=-6x^2-12x+2[/tex]

Step-by-step explanation:

Vertex form of a quadratic equation:  

[tex]y=a(x-h)^2+k[/tex]

where (h, k) is the vertex.

Given:

Substitute the given values into the vertex formula and solve for a:

[tex]\implies 2=a(0-(-1))^2+8[/tex]

[tex]\implies 2=a(1)^2+8[/tex]

[tex]\implies 2=a+8[/tex]

[tex]\implies a=-6[/tex]

Substitute the vertex and the found value of a into the vertex formula, then expand to standard form:

[tex]\implies y=-6(x-(-1))^2+8[/tex]

[tex]\implies y=-6(x+1)^2+8[/tex]

[tex]\implies y=-6(x^2+2x+1)+8[/tex]

[tex]\implies y=-6x^2-12x-6+8[/tex]

[tex]\implies y=-6x^2-12x+2[/tex]

Therefore, the quadratic function in standard form whose graph has the given characteristics is:

[tex]y=\boxed{-6x^2-12x+2}[/tex]
