Answer:
D
Step-by-step explanation:
your function is not very clear but I'm assuming it's 2 multiplied by 7^x
first let y be equal to the function
to find the range interchange x and y and make the subject
at some point you'll have to use logarithm to get rid of the exponent
only log of positive numbers numbers exist hence y must be greater than 0
There are 4 prime numbers from 1 to 10: 2, 3, 5, and 7. This means that there are 4 ways to choose the first outcome. There are 5 composite numbers from 1 to 10: 4, 6, 8, 9, and 10 (1 is just 1). So, you just multiply the two numbers together because each depends on each: 4 * 5 = 20 outcomes.

Answer:
$8.33
Step-by-step explanation:
there is 128 ounces in 1 gallon and she paid $15.36. if im correct you need to divide the price she paid by the ounces so 15.36÷128 = 8.333333333 and that would mean it's $8.33 per fluid ounce. I hope I did more help than hurt good luck
Answer:
64 model cars.
Step-by-step explanation:
What we know.
Cory has 80 cars in his collection.
That is 25% more than Everett has.
We can deduce that the equation would be c = 1.25e.
So, how do we figure out e?
Well, 1.25 is the same as 5/4.
So, find the reciprocal of 5/4 and multiply by 80.
4/5 * 80 = e
64 = e
