Answer:

Step-by-step explanation:
The given expression is;

This implies that;

Equate the exponents;

Expand;




The triangle is a right triangle so use the Pythagorean theorem.
a² + b² = c²
15² + b² = 17²
225 + b² = 289
b² = 64
b = √64
b = 8

Answer:
i think it means to just plot j at -6 on the x axis and 1 up on y axis
Answer:
I just learned this topic and have the same question, so I'm not sure if this right. However, I see a fellow student struggling and have to at least put in what I know. My equation was f(n) = 64(1/2)^n-1, then the question was write an expression to represent f(20).
Step-by-step explanation:
So, my answer was f(20) = 64(1/2)^19
f(20) is the number you plug into n. And because the exponent is n-1, I knew to subtract 1 from 20 to get 19.
Then I just wrote the equation out like the original expect with the numbers pluged in: f(20) = 64(1/2)^19
I hope this helps!
