Answer:
y = 2 * 9 ^ x
Step-by-step explanation:
From the first point, you can get the value of a, since any number with power 0 with always equal to 1
Now you have y = (2)(b ^x), use the second point, substitute the value of X and y to (3,1458) to get the B value.
- 1458 = 2b ^ 3
- 729 = b ^ 3
- B = 9
Answer:
16
Step-by-step explanation:
There are numerous ways to work a problem like this. One is shown above, where we multiply by the inverse of the denominator.
For this you can always use a calculator. Be sure to use parentheses around the denominator fraction.
600 *2*x + 150*4*x = 90
1200x + 600x = 90
1800x = 90
x = 90/1800 = 0.05
x = 5%
