Answer:

C; The left end goes up; the right end goes down

Step-by-step explanation:

If you expand the function, you end up with a polynomial with a negative coefficient and it has an odd power. According to polynomial behaviors of a function that is odd negative, the graph will rise to the left (y → ∞ and x → -∞) and falls to the right (y → -∞ and x → ∞).

ANSWER

C. The left end goes up; the right end goes down.

EXPLANATION

The given function is

f(x) =  - 2( {x - 2)}^{5}

We analyze the end behavior of this function using the leading term.

The leading term of this function is:

- 2 {x}^{5}

Since the degree(5) is odd and the leading coefficient (-2) is negative, the graph rises on the left and falls on the right.

In other words, the left end of the graph goes up and the right end goes down.

The correct option is C.

This section of a concrete skateboard ramp has the shape of a triangular prism. Find the volume of the triangular prism. Find th
NISA [10]

Answer:

The volume of the triangular prism: 59.2 ft^{3}

The value of the concrete used is: 16*4 = $64

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  Please have a look at the attached photo

My answer:

As we know that, the formula to find out the volume of the triangular prism is:

V = \frac{1}{2} a*b*h when h is the height and a&b are the length of the two square edges. So we have:

  • V = \frac{1}{2}*4*4*7.4 = 59.2 ft^{3}

To find the concrete used in the ramp if the cost of concrete is $ 4.00 per cubic foot, we need to know the area of the ramp, which is:

S = 4*4 = 16 ft^{2}

Hence, the value of the concrete used is: 16*4 = $64

Solve −3x2 − 4x − 4 = 0
kkurt [141]
This is a quadratic formula with a general form of a²x + bx + c = 0. For quadratic equations, we can solve for its two roots using the quadratic formula shown in the attached picture.

a = -3
b = -4
c = -4

x = [-(-4) + √(-4)² - 4(-3)(-4)]/2(-3) = <em>2 + √-32/2</em>
x = [-(-4) - √(-4)² - 4(-3)(-4)]/2(-3) =<em> 2 - √-32/2</em>
