hey can someone please help me i don’t understand this? the question says “find the surface area of the rectangular prism.”

ASHA 777 [7]

Answer:

170 in^2

Step-by-step explanation:

you have to find the area of each surface of the square

1) the square on the right side:

5x5=25 in^2

there are 2 of these on opposite sides

2)the of the rectangle facing us;

6x5=30in^2 (5 because 5 is the height)

there are 4 of these

3)add up all the areas

25+25+30+30+30+30=170in^2

A hovercraft takes off from a platform. Its height (in meters), xx seconds after takeoff, is modeled by: h(x)=-2x^2+20x+48h(x)=?

tangare [24]

Answer: 5 seconds

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

Maximum height is the y-value of the vertex. The number of seconds at maximum height is the x-value (aka axis of symmetry).

h(x) = -2x² + 20x + 48

a=-2 b=20 c=48

Axis of symmetry: x = $\frac{-b}{2a}$

= $\frac{-20}{2(-2)}$

= $\frac{-20}{-4}$

= 5

Find f(-2) for f(x) = 2(4)x . will give brainliest for correct answer

Serhud [2]

Answer:

Step-by-step explanation:

This questions asks use to find what f(x) or y is, when x is equal to -2.

So, substitute -2 in for x in the equation.

f(x)=2(4)^x

f(-2)=2(4)^-2

Evaluate the exponent. Negative exponents follow this rule:

b^-x= 1/b^x

We have 4^-2. This will become 1/4^2 or 1/16

f(-2)=2(1/16)

Multiply

f(-2)=2/16

This fraction can be simplified. Both the numerator (top number) and denominator (bottom number) can be divided by 2.

f(-2)=2/2 / 16/2

f(-2)= 1/8

The correct choice is D. 1/8

If there are 37 figures and there are six people how many will each person get

Elis [28]

Answer:

It depends.

Step-by-step explanation:

If we're able to brake the figures, then each person will get six and one sixth of a figure

$37 \div 6 = 6 \frac{1}{6}$

But if we can't break them, then each person will get six figures with one remaining ungiven.

$37 \div 6 = 6 \: (1)$
