What is the surface area of the triangular prism

Harrizon [31]

Answer:

$surface \: a = 9 \times 5 \\ = 45ft \times 2 \\ = {90}^{2} ft\\ surface \: b = \frac{1}{2} bh \\ = \frac{1}{2 } \times 6 \times 4 \\ = 3 \times 4 \\ = 12 \times 2 \\ = {144}^{2} ft \\ = 90 + 144 \\ = {234}^{2} ft$

PLS HELP I WILL MARK YOU BRAINLIEST!!!! The table represents some points on the graph of an exponential function.

Usimov [2.4K]

<h3>Answer: Choice B</h3><h3>f(x) = 18(6/5)^x</h3>

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

Explanation:

When x = 0, we have y = 18. The y intercept value is 18. This is the initial value, and it's the value of 'a' in the equation below

y = a*b^x

The value of b is tied to the growth or decay rate, depending on if b > 1 or if 0 < b < 1 respectively.

In this case, we have growth due to y increasing as x increases. They increase together.

When x increases by 1 like this, the value of b can be determined by dividing any y term over its previous value. So for instance, we can say b = 21.6/18 = 1.2 or we could say b = 25.92/21.6 = 1.2

Then note how 1.2 = 6/5, which means b = 6/5

Therefore, y = a*b^x becomes y = 18(6/5)^x

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

We can confirm this equation by plugging in x values from the table and we should get the y values, or f(x) values, listed

Example: plug in x = 0 to find that

y = 18(6/5)^x

y = 18(6/5)^0

y = 18(1)

y = 18 which matches

Then try x = 1

y = 18(6/5)^x

y = 18(6/5)^1

y = 18(1.2)

y = 21.6 that also matches

I'll let you confirm the other x values.

Find x (2x+1) (5x+5)

mezya [45]

explanation;

Solution for 2x+1=5x-5 equation

Simplifying

2x + 1 = 5x + -5

Reorder the terms:

1 + 2x = 5x + -5

Reorder the terms:

1 + 2x = -5 + 5x

Solving

1 + 2x = -5 + 5x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-5x' to each side of the equation.

1 + 2x + -5x = -5 + 5x + -5x

Combine like terms: 2x + -5x = -3x

1 + -3x = -5 + 5x + -5x

Combine like terms: 5x + -5x = 0

1 + -3x = -5 + 0

1 + -3x = -5

Add '-1' to each side of the equation.

1 + -1 + -3x = -5 + -1

Combine like terms: 1 + -1 = 0

0 + -3x = -5 + -1

-3x = -5 + -1

Combine like terms: -5 + -1 = -6

-3x = -6

Divide each side by '-3'.

x = 2

Simplifying

x = 2
