Answer: 14
Step-by-step explanation: The perimeter is all of the side added together. When finding the perimeter of a rectangle the opposing sides have the same value. So the equation would be 2(12) + 2(a) = 52. 12 x 2 is 24. 52- 24 is 28 and youre left with 28 = 2(a). You divide each side by 2 and get 14 = a
Answer: (2,5)
Step-by-step explanation:
To find the x coordinate of the vertex, you will set x-2=0 and solve for x
x-2=0
+2 +2
x = 2
Now since we know the vertex has an x coordinate of 2 we have to solve for y by plotting in the x value.
y= 1/2(2-2)^2 + 5
y = 0 +5
y =5
(2,5)
Answer:
$6
Step-by-step explanation:
We have: The cost of a taxi ride is represented by the function c(m)=2m+4
Plug 1 mile into "m" of the function c(m)=2m+4
So, we have c (1) = 2 ˣ 1 + 4 = 6
Thus, The cost per mile of the cab is $6.
