Answer: c) 3

<u>Step-by-step explanation:</u>

Plug in y = -9 and the given x-value to see if it makes a true statement.

a) -4.5 falls in the piecewise function x < -3 --> y = -x

y = -x

-9 = -(-4.5)

-9 = 4.5 FALSE

b) -3 falls in the piecewise function -3 ≤ x ≤ -2 --> y = 2x

y = 2x

-9 = 2(-3)

-9 = -6 FALSE

c) 3 falls in the piecewise function x > -2 --> y = -x²

y = -x²

-9 = -(-3)²

-9 = -9 TRUE

d) 9 falls in the piecewise function x > -2 --> y = -x²

y = -x²

-9 = -(9)²

-9 = -81 FALSE

Answer:

Formula used :

(a^m)^n = a^(m×n)
a^m × a^n = a^(m+n)

$27 \times {9}^{3x} = {3}^{k} \\ {3}^{3} \times { {(3}^{2}) }^{3x} = {3}^{k} \\ {3}^{k} = {3}^{3} \times {3}^{(2 \times 3x)} \\ {3}^{k} = {3}^{3} \times {3}^{6x} \\ {3}^{k} = {3}^{(6x + 3)} \\ \boxed{k = 6x + 3}$

<u>k = (6x+3)</u> is the right answer.

Ron and Freddy built structures out of snap cubes. Ron's tower had an 8-inch square base. Freddy had a 6-inch square base. If Ro

Sphinxa [80]

Answer: Ron tower's

Step-by-step explanation:

Given

Ron tower has a base of $A_r=8\ in.^2$

Freddy tower has a base of $A_f=6\ in.^2$

Suppose the tower is in the shape of a square prism

The volume of Ron and Freddy tower is $320\ \text{and}\ 180\ in.^3$

The volume of a square-based prism is $V=\frac{1}{3}a^2h$

$\therefore \text{height of Ron tower is}\ h_r=\dfrac{3V}{A_r}\\\\\Rightarrow h_r=\dfrac{3\times 320}{8}=120\ in.$

The height of Freddy tower is

$\Rightarrow h_f=\dfrac{3V}{A_f}\\\\\Rightarrow h_f=\dfrac{3\times 180}{6}=90\ in.$

Thus, the height of Ron's tower is more than Freddy's tower by $30\ in.$

Given: a quadratic function with vertex (2,3) opening upward .

Find: the given statement is true or false.

Explanation: if parabola has a vertex at (2,3) and opens upward, it has one real solution., (2,3) will be a lowest point. The vertex will be at lowest point, it will be minimum.

that means graph has no one real solution. hence it will never going to intersect. so this statement is false.

Final answer: the given statement is FALSE.
