Answer:
140 is the answer for y2 because x1 is 80 more than x2 so you would subtract y2 by 80
Answer:
A general exponential equation is written as:
f(x) = A*(r)^x
Where:
A is the initial value, this is the value that the function takes when x = 0.
r is the rate of growth
x is the variable.
In this case, the function is:
f(x) = 2*(4)^x
The initial value is:
f(0) = 2*(4)^0 = 2*1 = 2
The initial value is 2.
And the rate of growth is 4.
So Martin seems to mixed these two values (he said initial value = 4, and rate = 2, which is the opposite of what we found)
Yeah cuz u could +1 to each side of the second equation to get rid of both the -1’s and that is equivalent to the first equation :)
Answer:
Daeja is correct.
Step-by-step explanation:
Equation: 6 = 1/2s
Solve:
(2)6 = 1/2s(2) <== multiply both sides by 2
12 = s or s = 12
Therefore, Daeja is correct.
I multiplied both sides by 2 to isolate s, and 2 ⋅ 6 is 12.
Hope this helps!
Answer:
Total surface area of cube = 294 cm²
Step-by-step explanation:
Given:
Perimeter of cube = 84 cm
Find:
Total surface area of cube
Computation:
Perimeter of cube = 12 x side
84 = 12 x side
Side = 7 cm
Total surface area of cube = 6(a)²
Total surface area of cube = 6(7)²
Total surface area of cube = 294 cm²
