Answer: 34y
Step-by-step explanation:
So first you have to round the nearest 2 to the nears 3 then you get 30 then you have to add 4 the add you variable.
Answer:
Is this multiple choice?
Step-by-step explanation:
Dunno if there are answers to choose from, but I will give ya the answer to the expression:
8^−4⋅8^3 = 0.125
Expressions equivelant to that include:
1 ÷ 8
8^-1
Also, this is assuming that 8^−4 is 8^-4 and not something else. If it is something else, then disregard this answer, because the calculations were made with 8 to the power of negative 4.
Hope that helped, if it is multiple choice just check each expression and see if it is equal to 0.125.
Answer: 30 students
Step-by-step explanation:
Multiply total number of students (125) by the percentage (25)
Turn the 25 into a decimal -> .25
Answer:
C
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ - 10, 10 ], thus
f(b) = f(10) = 10² + 9(10) + 18 = 100 + 90 + 18 = 208
f(a) = f(- 10) = (- 10)² + 9(- 10) + 18 = 100 - 90 + 18 = 28, thus
average rate of change = 
= 
= 9
