Answer:

x = 15

Step-by-step explanation:

We need to use Pythagoras Theorem to find the value of x. Usually we use Pythagoras to work out the hypotenuse (the side opposite the right-angle) but we are given the hypotenuse, so we will have to rearrange.

→ Form equation

20² + b² = 25²

→ Simplify

400 + b² = 625

→ Minus 400 from both sides to isolate b²

b² = 225

→ Square root both sides to isolate b

b = 15

Answer:

x = 15

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 20² = 25²

x² + 400 = 625 ( subtract 400 from both sides )

x² = 225 ( take the square root of both sides )

x = $\sqrt{225}$ = 15

The question is: "Without actually graphing, describe how the graph of y = ( -2^(x+17) ) - 4.3 is related to the graph of y = 2^

Answer:

The function has been flipped due to the negative in front.

The function has been shifted 17 units to the left.

The function has been shifted 4.3 units down.

Step-by-step explanation:

When functions are transformed there are a few simple rules:

Adding/subtracting inside the parenthesis to the input shifts the function left(+) and right(-).
Adding/subtracting outside the parenthesis to the output shifts the function up(+) and down(-).
Multiplying the function by a number less than 1 compresses it towards the x-axis.
Multiplying the function by a number greater than 1 stretches it away from the x-axis.
Multiplying by a negative flips the graph.

The graph of $(-2^{x+17}) -4.3$ compares to $2^x$ in the following ways:
