Answer:

Step-by-step explanation:

If we want to find the axis of symmetry of the parabola of [tex]y=-4x^{2} -8x-7,[/tex] we would use the formula of [tex]-\frac{b}{2(a)}[/tex] to find it.

b=-8

a=-4

so the formula would look like this [tex]-\frac{-8}{2(-4)}[/tex], simplify it >>>[tex]-\frac{-8}{-8}[/tex] which is -1

So -1 would be the axis of symmetry

Answer:

e - 50°

f - 65°

Step-by-step explanation:

Both triangles are 180°

So basically just add 50+65 which gives you 115 and that is 'g' cause that is the last missing piece of the left triangle.

Answer:

A thesis statement is a claim

Step-by-step explanation:

The thesis statement is the sentence that states the main idea of a writing assignment and helps control the ideas within the paper. It is not merely a topic. It often reflects an opinion or judgment that a writer has made about a reading or personal experience. For instance: Tocqueville believed that the domestic role most women held in America was the role that gave them the most power, an idea that many would hotly dispute today.

Answer:

The effective annual rate is 11.03%

Step-by-step explanation:

The effective interest rate is calculated through the formula:

[tex]r = (1 + i/n)^n - 1[/tex]

In this formula, r represents the effective interest rate, i represents the stated interest rate or APR, and n represents the number of compounding periods per year.

For a quarterly compounded interest, n=4. The APR i=10.60%=0.106

Given an APR r, the effective annual rate for a quarterly compound is:

[tex]r = (1 + 0.106/4)^4 - 1=1.0265^4-1[/tex]

[tex]r=1.11029-1=0.1103[/tex]

The effective annual rate is 11.03%

Answer:

4.5inches

Step-by-step explanation:

Given the volume of a prism expressed as:

V =lwh where:

l is the length

w is the width,

h is the height of the prism.

Given

V = 138.24in³

h = 9.6in

l = 3.2in

w = ?

Substitute the given values into the formula to get the width

138.24 =  9.6*3.2*w

138.24 = 30.72w

w = 138.24/30.72

w = 4.5in

Hence the width of the rectangular prism is 4.5inches

The width of the rectangular pyramid that has a volume of 138.24 cubic inches, a height of 9.6 inches, and a length of 3.2 inches is 4.5 inches.

where

l = length

w = width

h = height

v = 138.24 inches³

h = 9.6 inches

l = 3.2 inches

w  = ?

138.24 = 9.6 × 3.2 × w

138.24 = 30.72w

w = 138.24 / 30.72

w = 4.5 inches

Answer:

we are given

parent function as

(1)

vertical stretch of factor 2

so, we can multiply y-value by 2

then a shift right of 3 units

so, we can replace x as x-3

(2)

a shift left by 2 units

we can replace x as x+2

then a horizontal shrink factor of 1/2

so, we can multiply by 2 to x-value

then a shift down of 5 units

we can subtract y-value by 5

so, we get

(3)

a shift to the right 1 unit

we can replace x as x-1

stretched vertically by a factor of 1/2

we can multiply y-value by 1/2

then is shifted down 4 units

we can subtract y-value by 4

(4)

reflected across the x-axis

we can multiply y-value by -1

tretched vertically by a factor of 3

multiply y-value by 3

shifted left 7 units

we can replace x as x+7

Step-by-step explanation:

The amount of kinetic energy required to move a couch is most likely to be a function of the weight of the couch.

In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity.
