Answer:
B. y = 10(2)^x
Step-by-step explanation:
y = ab^x
to find "b" divide the function at x = 3 by the function at x = 2
80 = ab^3
——————
40 = ab^2
This results in
2 = b
to find "a" plug pickany value of x
using x = 2
40 = a(2²)
40 = a(4)
a = 10
With a = 10 and b = 2 the exponential function y = ab^x is
y = 10(2)^x
Answer:
Step-by-step explanation:
Divide n by 100,000.
This gives us the "number of times 100,000 fits in n", or, "how many 100,000's n is", or as the hint says, "how many times larger n is than 100,000".
All represented by this formula:
We use the Pythagorean theorem here, because we have the two sides and a right angle between them, so we calculate the hypotenuse like this:
x^2 = 6^2 + 8^2
x^2 = 36 + 64
x^2 = 100
x = square root of 100
x = 10
The correct answer is B.10.
Answer:
