Step-by-step explanation:
-x+7=-0.5(x-3)^2+8
-x+7=-0.5x^10 -4.5^10
am I getting ...!?
Answer:
(-1,6) and (-7,0)
Step-by-step explanation:
-x+7=-0.5(x-3)^2+8
times both sides by -2
2x-14=(x-3)^2-16
expand
2x-14=x^2-6x+9-16
add 14-2x to both sides
0=x^2-8x+7
factor
0=(x-7)(x-1)
set to zero
0=x-7
7=x
0=x-1
1=x
so find y
y=-x+7
y=-1+7
y=6
or
y=-7+7
y=0

Answer:
Since the shape was formerly a square,ofarea 100in²
Then,Area of square=side×side
100in²=side²
side=√100in²
side=10 inches
Perimeter of the shape=10+10+7+6+5
=38inches
Now a length of 3inches is cut off from the upper horizontal side and a length of 4in is also cut off from the right vertical side.
So now we can say a triangle of base 4in and height 3in is cut off from the square.
Area of cut off triangle=½base×height
=½×4×3=0.5×12
=6 inches ²
So the Area of the shape=Area of square-Area of triangle
=100-6=94inches²

Correct the error. Perimeter =4+3+4+5+ = in.

Answer: You are missing a 4.
Step-by-step explanation: If you said the answer is 20, 4 is missing. We can add up the follow equation before putting 4.
(4 + 3) + (4 + 5)
7 + 9 = 16 + 4 = 20.
Hence, 20 is your answer.
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

List at least 3 ways you can use a table or a graph to determine if a function is linear or nonlinear.
Answer:
1) if you use the graph, it should go in a straight line, if it does, it’s linear.
2) if you use a table, you can see to make sure the numbers go up/down at the same rate
3) if you have a graph and a table, you could always compare both, and make sure they’re both linear
A high school track is shaped as a rectangle with a half circle on either side. Jasmine plans on running three laps. How many yards will Jasmine run? Use 3.14 for Pi.
A. 248.5 yd
B. 490.5 yd
C. 725.5 yd
D. 745.5 yd
Step-by-step explanation:
= 25 yards ; r = 25/2 = 12.5 yards
circumference of two semicircle = circumference of circle
= 2πr = 2*3.14*12.5 = 78.5 yards
Perimeter of school truck = 78.5 + 85 + 85 = 248.5 yards
Distance traveled by Jasmine = 3* 248.5 = 745.5 yards

Write a quadratic function whose graph has a vertex of (3,2) and passes through the point (4,7). f(x)=
Answer:
y=5(x-3)^2+2
Step-by-step explanation:
You plug the point into f(x)=a(x-3)^2+2... that already has already been solved for the vertex that you want. Then you swap it out for the solution you have solved for.
The required function is [tex]f(x)=5(x-3)^2+2[/tex].
Important information:
Vertex of a quadratic function is (3,2).The graph passes through the point (4,7).Quadratic function:The vertex form of a quadratic function is:
[tex]f(x)=a(x-h)^2+k[/tex]
Where, [tex]a[/tex] is a constant and [tex](h,k)[/tex] is vertex.
Substitute [tex]h=3,k=2[/tex].
[tex]f(x)=a(x-3)^2+2[/tex] ...(i)
The graph passes through the point (4,7). Substitute [tex]x=4, f(x)=7[/tex] in (i).
[tex]7=a(4-3)^2+2[/tex]
[tex]7=a+2[/tex]
[tex]7-2=a[/tex]
[tex]5=a[/tex]
Substitute [tex]a=5[/tex] in (i).
[tex]f(x)=5(x-3)^2+2[/tex]
Therefore, the required function is [tex]f(x)=5(x-3)^2+2[/tex].

Fine two integers that have a sum of -17 and a product of 52. What are the integers?
Answer:
{4, 13}
Step-by-step explanation:
Represent the integers by I and J. Then I + J = -17 and I*J = 52.
Let's solve this system using substitution. Solve the first equation for I as follows:
I + J = -17 becomes I = -J - 17
Substitute -J -17 for I in the second equation:
(-J - 17)*J = 52
Performing the indicated multiplication, we get:
-J^2 - 17J - 52 = 0
Let's solve this using the quadratic formula. The quadratic coefficients here are {-1, -17, -52}, and so the discriminant, b^2 - 4ac, is
(-17)^2 - 4(-1)(-52), or 289 - 208, or 81. This result is positive, so we know that the quadratic equation has two real, unequal roots. They are:
17 ± √81 17 ± 9
J = --------------- = ---------------
2(-1) -2
Evaluating this last result, we get J = (17 + 9)/2, or J = 13, and
J = (17 - 9)/2 = 8/2, or J = 4
