Answer:
Correct answer is f(x) = (625^x)^1/4
Step-by-step explanation:
We know that
625 = 5^4
This means
f(x) = (625^x)^1/4
f(x) = (5^(4x))^1/4
But we know this is equivalent to
f(x) = (5^(4x*(1/4))) =
= 5^(x)
Correct answer is f(x) = (625^x)^1/4
I just took the test online. The answer is $8.05. Hope this helps!
A 7 to 3 ratio means that for every time they sell 7 burgers with cheese sold, they also sold 3 burgers without cheese.
So you solve this by figuring out how many times they sold 7 burgers and then you use that number to find your answer.
35 / 7 = 5
So they sold 7 burgers 5 times.
So that means that they also sold 3 burgers 5 times since for every 7 burgers with cheese they sell 3 burgers without cheese.
So 3 * 5 = 15
You then add your two numbers and you have your answer.
35 burgers with cheese + 15 burgers without cheese = 50 burgers total.
Answer:
Step-by-step explanation:
for question 5 )
we know that x-5 = 6 because I'm pretty sure outside of the question we are told that the rectangles are similar and therefore, we can say the above
x-5 = 6
add 5 to both side
x = 11
for question 6)
30 is
of 36, so use that on the remaining given side
* 15 = 12.5
then thats what the other side of the bigger shape is
12.5 = x + 6
minus 6 from both sides
6.5 = x
by the way, notice that they have used a variable "x" for both 5 & 6 which is named the same but has a different value in each problem. X is the name of the variable for each problem, but doesn't have any meaning once outside of each of the problems. It's just confusing to use the same named variable at times. something like xy and xz , might have been better names. anyway :)
Answer:
y = x^2 -6x -27
Step-by-step explanation:
When "a" is a root, (x-a) is a factor. The minimum polynomial with the listed roots will be ...
y = (x -9)(x +3)
y = x^2 -6x -27
