Answer:
13). y = x² + 6x + 8
14). y = 2x² + 8x - 12
Step-by-step explanation:
13). Vertex form of a parabola is given by,
y = a(x - h)² + k
Here (h, k) is the vertex of the parabola.
Equation of a parabola with vertex (-3, -1) will be,
y = a(x + 3)² - 1
Since, y-intercept of the parabola is y = 8
In other words, parabola is passing through (0, 8)
8 = a(0 + 3)² - 1
8 = 9a - 1
9a = 9
a = 1
Therefore, equation of the parabola will be,
y = (x + 3)² - 1
y = x² + 6x + 9 - 1
y = x² + 6x + 8
14). Equation of a parabola with vertex (-2, -20)
y = a(x + 2)² - 20
Since, y-intercept of the parabola is (0, -12),
-12 = a(0 + 2)² - 20
-12 + 20 = 4a
4a = 8
a = 2
Therefore, equation of the parabola will be,
y = 2(x + 2)² - 20
y = 2(x² + 4x + 4) - 20
y = 2x² + 8x + 8 - 20
y = 2x² + 8x - 12

What is fraction?The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.
The number of parts into which the whole has been divided is shown by the denominator. It is positioned in the fraction's lower portion, below the fractional bar.How many sections of the fraction are displayed or chosen is shown in the numerator. It is positioned above the fractional bar in the upper portion of the fraction.Given:
Fraction : 4 7/500
Now, writing the fraction in normal fraction form
= 4 7/500
= 2007/500
Now, to convert into percent
= 2007/ 500 x 100
= 2007/ 5
= 401%

Matthew took a cab home from his office. The cab charged a flat fee of $4, plus $2 per mile. Matthew paid $34 for the trip Write an equation to show the number of miles Matthew drove
Answers
Answer:
(34-4)/2
Step-by-step explanation:
First you would subtract the flat fee of 4 dollars from the total ($34) which would give you 30 then you divide 30 by the rate or dollars per mile (2) which would leave you with 15 so he drove 15 miles and if you were to writ this as an equation (as shown above) it would look like this (34-4)/2 where you first subtract (hence the parentheses) then you would divide (hence the / ).

A full 335 ml can of Coca-Cola is filtered at a rate
of 5 ml per minute into an empty can. How long
will it take for the two cans to have the same
amount, a, of Coca-Cola?
Mm
Answers
9514 1404 393
Answer:
33.5 minutes
Step-by-step explanation:
There are many ways you can look at this problem. One is to write equations for the amount in each can, and solve for the time that makes those amounts equal. Another is to consider how much time it takes to reduce the volume by half.
Using the first method, we have ...
335 -5t = 5t
335 = 10t
335/10 = 33.5 = t
It takes 33.5 minutes for the cans to have the same amount.

Lamar is considering two loans.
Loan A
Loan B
Principal
$4,500
$4,300
Interest rate
5%
6%
Time in years
3
3
Which loan will have the lowest total payback?
Answers
Step-by-step explanation:
know:
Loan A
Principal
$4500
Interest rate
5%
Time in years
3
If 100% => $4500
5% =>X
X = 5% × $4500 ÷ 100% = $225
Loan A = $4500 + $225 = $4725
Loan B
Principal
$4300
Interest
6%
Time in years
3
If 100% => $4300
6% =>X
X = 6% × $4300 ÷ 100% = $258
Loan B = $4300 + $258 = $4558
Loan B has the lowest total payback.
The Loan B has the lowest total payback than the Loan A.
How to calculate the Payback?WE can calculate the payback in both loan as;
Loan A;
Principal = $4500
Interest rate = 5%
Time in years = 3
If 100% => $4500
X = 5% × $4500 ÷ 100%
X = $225
Loan A = $4500 + $225 = $4725
Loan B;
Principal = $4300
Interest = 6%
Time in years = 3
If 100% => $4300
X = 6% × $4300 ÷ 100%
X= $258
Loan B = $4300 + $258 = $4558
Hence, the Loan B has the lowest total payback than the Loan A.
