A pair of sneakers that cost $90 last year has now been marked up 25%. Mariel has a coupon that is going to take 10% off the price of the shoes. Is the price that she will pay equivalent to a 15% markup of the original cost of the shoes? Show your work.
Answer:
Your answer is no.
Step-by-step explanation:
The answer is no because when using the coupon she's only getting 10% off of the price AFTER 25% is added.
10% off of the original price is: $81.00
10% off of the new price is: $101.25
Need help with question 4 :(
PLEASE HELP ME BRAINLISET FOR RIGHT ANSWER!!
Answer:
1. No, Student 1 did not make any errors. However, their use of a ruler, or lack of thereof, could result in a lack of accuracy.
2. The student manually found the points and connected them together, doing so for both A and B and thus finding the intersection.
3. Since there is no formula used, the result may not be accurate. The student can only guess the position of the intersection, not know exactly (i.e. when the points are positioned at decimal numbers.)
Answer:
for answer 1 its no
for 2 the person found the points and connected them
for 3 no formula so its not accurate
my brother is in high school and this is what he told me it was if its wrong im sorry my brother is an idiot lol

1. The figure shows a graph of the function of f(x) in the xy-coordinate plane, with the vertex at (1,9) and the zeros
at -2 and 4.

The function g is defined by g(x) = -3x + 2. Which statements are true? Select ALL that apply.
f{-2) is greater than g(-2).
f{-1) is less than g(-1).
f{0) is greater than g(0)
f(1) is less than g(1).
f(2) is greater than g(2).
Answer:
f{0) is greater than g(0) and f(2) is greater than g(2).
Step-by-step explanation:
f{0) is greater than g(0) = f(0)=8 and g(0)=2
f(2) is greater than g(2) = f(2)=8 and g(2)= -4
The two statements that are correct are f(0) is greater than g(0), and f(2) is greater than g(2).
What is the general equation of parabola?The general equation of a parabola is given as,
[tex]y=a(x-h)^2+k[/tex]
where (h,k) is the coordinate of the vertex of the parabola.
The equation of the parabola with vertex (1,9) can be written as,
[tex]y=a(x-h)^2+k\\\\y=a(x-1)^2+9[/tex]
Now, the value of a can be found by putting one zero of the parabola,
[tex]y=a(4-1)^2+9\\\\0=a(3)^2+9\\\\-9=a(3)^2\\\\-9=a9\\\\a=-1[/tex]
Thus, the equation of the parabola can be written as y=-(x-1)²+9.
A.) The value of the two functions when the value of x is -2 can be written as,
[tex]f(x)=-(x-1)^2+9\\\\f(-2)=-(-2-1)^2+9\\\\f(-2)=0[/tex]
[tex]g(x) = -3x + 2\\\\g(-2) = -3(-2) + 2\\\\g(-2)=8[/tex]
Therefore, f(-2) is less than g(-2).
B.) The value of the two functions when the value of x is -1 can be written as,
[tex]f(x)=-(x-1)^2+9\\\\f(-1)=-(-1-1)^2+9\\\\f(-2)=5[/tex]
[tex]g(x) = -3x + 2\\\\g(-1) = -3(-1) + 2\\\\g(-1)=5[/tex]
Therefore, f(-1) is equal to g(-1).
C.) The value of the two functions when the value of x is 0 can be written as,
[tex]f(x)=-(x-1)^2+9\\\\f(0)=-(0-1)^2+9\\\\f(0)=8[/tex]
[tex]g(x) = -3x + 2\\\\g(0) = -3(0) + 2\\\\g(0)=2[/tex]
Therefore, f(0) is greater than g(0).
D.) The value of the two functions when the value of x is 1 can be written as,
[tex]f(x)=-(x-1)^2+9\\\\f(1)=-(1-1)^2+9\\\\f(1)=9[/tex]
[tex]g(x) = -3x + 2\\\\g(1) = -3(1) + 2\\\\g(1)=1[/tex]
Therefore, f(1) is greater than g(1).
E.) The value of the two functions when the value of x is 2 can be written as,
[tex]f(x)=-(x-1)^2+9\\\\f(2)=-(2-1)^2+9\\\\f(2)=8[/tex]
[tex]g(x) = -3x + 2\\\\g(2) = -3(2) + 2\\\\g(2)=-4[/tex]
Therefore, f(2) is greater than g(2).
Thus, the two statements that are correct are f(0) is greater than g(0), and f(2) is greater than g(2).

Clare estimates that her brother is 4 feet tall. When they get measured at the doctor’s office, her brother’s height is 4 feet, 2 inches.
1. Should Clare's or the doctor's measurement be considered the actual height? Explain your reasoning.
2. What was the error, expressed in inches?
3. What was the error, expressed as a percentage of the actual height?
Answer:
Percentage of error by Clare is estimated as 4.1667 %
Step-by-step explanation:
Height measured by Clare = 4 feet
Height measured by Doctor = 4 feet, 2 inches
Percentage error = ?
Percentage error = Difference/ Actual height *100
Percentage error = (2/ (4*12))*100
Percentage error = 4.1667 %
The accurate height is measured by Doctor, as he have more accurate measurement system.
