A quadratic function has one root at 5 and has a vertex point at (7, 2).
What is the value of “a”?
[tex]y = a {(x - h)}^{2} + k[/tex]
where a-term determines the shape of graph.
h-term determines the change of graph for x-axis.
k-term determines the change of graph for y-axis.
Vertex of the graph is at (h,k).
Substitute the vertex value in the equation.[tex]y = a {(x - 7)}^{2} + 2[/tex]
We need to find the value of a-term. We have the given root which we can substitute in the equation.
Also the roots are on x-axis, meaning that the y-value for roots must be 0.
Substitute (5,0) in the equation.[tex]0 =a {(5 - 7)}^{2} + 2 \\ 0 =a {( - 2)} ^{2} + 2 \\ 0 = 4a + 2[/tex]
Solve for a-term.[tex]4a + 2 = 0 \\ 4a = - 2 \\ a = \frac{ - 2}{4} \\ a = - \frac{1}{2} [/tex]
Therefore the value of a is - 1/2. Rewrite the equation as we get the answer.
Answer[tex] \large \boxed{y = - \frac{1}{2} {(x - 7)}^{2} + 2}[/tex]

Step-by-step explanation:
the distance around the figure--we need to find the perimeter
we have rectangle that has the side, 8 and 15
P(r)=2(8)+2(15)=16+30=46
we also have half of the circle with the diameter =8 and r=4
Circumference =2*3.14*r
C=2*3.14*4=25.12
we need just half of the circle 25.12/2=12.56
P figure=46+12.56=58.56
Area= rectangle=l*w=8*15=120
Area(circle)=3.14*r^2=3.14*16=50.24
half circle 50.24/2=25.12
Area figure=120+25.12=145.12

Little billy wants to buy a pineapple upside down came. The cakes are 2 days old so they are 70% off! The original price is $20. What is the sale price
Answer:
$6
Step-by-step explanation:
Original price of the pineapple = $20
Percentage off = 70%
Amount discounted = 70% of $20
Amount discounted = 0.7 * 20
Amount discounted = $14
Sale price = Original price - Discount
Sale price = $20 - $14
Sale price = $6
Hence the sale price was $6

In history class, Maria has nine tests. Her final grade in the class will be the median of her test scores. Each test is scored out of $100.$ Maria's first six test scores are $79,$ $84,$ $86,$ $92,$ $93,$ and $97.$ What is the highest possible final grade in the class she can still earn
Answer:
93
Step-by-step explanation:
Given the data:
$79,$ $84,$ $86,$ $92,$ $93,$ and $97
79, 84, 86, 92, 93, 97
Highest possible score obtainable in a test = 100
Hence to calculate the highest possible score she could still attain;
We assume she obtained a score of 100 in all remaining 3 tests
Then the data becomes :
79, 84, 86, 92, 93, 97, 100, 100, 100
Median of the dataset:
Q2 = 1/2(n + 1)th term
n = sample size = 9
Q2 = 1/2(9 + 1)th term
Q2 = 1/2(10)th term
Q2 = 5th term
Q2 = 93

As you can see in the image below the solution of the system of equations is (-7,-5).
The length of a pair of corresponding sides of two similar ∆'s are 3 cm and 11 cm. If the area of the first ∆ is 18 cm^2 find the area of the second ∆.
Answer:
The area of the second triangle is 242 cm²
Step-by-step explanation:
In the similar triangles
The ratio between their perimeters equals the ratio between their corresponding sidesThe ratio between their areas equals square the ratio between their corresponding sides∵ The length of a pair of corresponding sides of two similar ∆'s are
3 cm and 11 cm
→ Find the ratio of the corresponding sides
∴ The ratio of their corresponding sides = [tex]\frac{3}{11}[/tex]
∵ The area of the first ∆ is 18 cm²
→ Use the second rule above
∵ [tex]\frac{A1}{A2}[/tex] = [tex](\frac{3}{11}) ^{2}[/tex]
∵ A1 = 18 cm²
→ Substitute it in the ratio above
∴ [tex]\frac{18}{A2}[/tex] = [tex]\frac{9}{121}[/tex]
→ By using the cross multiplication
∵ A2 × 9 = 18 × 121
∴ 9A2 = 2178
→ Divide both sides by 9
∴ A2 = 242 cm²
∴ The area of the second triangle is 242 cm²

Jess rounds a number, x to one decimal place
The result is 9.8
Write down the error interval for X
The error interval when x is rounded off to 9.8 will be given as 9.75 ≤ x ≤ 9.84.
The number that is rounded off is:
x = 9.8
9.8 can be rounded off for 9.75 to 9.84
So, this means that:
9.75 ≤ x
or 9.84 ≥ x
So, the error interval becomes:
9.75 ≤ x ≤ 9.84
Therefore, we get that, the error interval when x is rounded off to 9.8 will be given as 9.75 ≤ x ≤ 9.84.

A class trip is planned for a cinema visit.
1/4 of the people walk to it.
1/3 of the people, get the bus.
The remaining 60 people get a lift in a car.
Calculate the number of pupils who get the bus and who walk to the cinema.
Answer: 48 pupils get the bus to the cinema and 36 pupils walk to the cinema.
Step-by-step explanation:
Let's suppose that there are a total of N pupils.
We know that N/4 walk to the cinema.
We know that N/3 get the bus to the cinema.
And the remainder is equal to 60 people.
Then:
N - N/4 - N/3 = 60
N*(1 - 1/4 - 1/3) = 60
N( 12/12 - 3/12 - 4/12) = 60
N*( 5/12) = 60
N = (12/5)*60 = 144
Then the number of pupils that walk to the cinema is N/4, or:
144/4 = 36
And the number of pupils that get the bus is N/3, or:
144/3 = 48.
