Let
C-----------------
> charges for the purchases to the credit card
<span>r-------------------
> the interest rate </span>
X------------------
> total cost of the purchase
we know that
C=4120
r= 22.45%=0.2245
X=C*(1+r)
substituting the values in the formula
X=(4120)*(1+0.2245)=
(4120)*(1.2245)=5044.94
the answer is
$5044.94
They are equal. 0.1x58=5.8, 5+0.8=5.8
1/2 + 1/2 + 2/3 + 3/4 + 47/48 + 48/49 +49/50 = 5.35542517007
This decimal form is ≈ to 5 2/5
Histograms are used to represent data, where the length of each bar represents the frequency of the data element
The histogram is not given; So, I will give a general explanation.
Assume that the number of commuters that travel more than 45 minutes is 450, while the total number of commuters surveyed is 500.
The percentage of commuters that travel more than 45 minutes is the quotient of the commuters that travel more than 45 minutes and the total number of surveyed commuters.
So, we have:

Divide 450 by 500

Express as percentage

Hence, the percentage of commuters that travel more than 45 minutes is 90%

Answer:
vertex = (- 1, 3 )
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
= - 
y = 2x² + 4x + 5 ← is in standard form
with a = 2, b = 4, then
= -
= - 1
Substitute x = - 1 into the equation for corresponding value of y, that is
y = 2(- 1)² + 4(- 1) + 5 = 2 - 4 + 5 = 3
vertex = (- 1, 3 )
