Answer:

[tex]\displaystyle f(x)=\frac{10}{169}\left(x-8\right)^2-1[/tex]

Step-by-step explanation:

We can use the vertex form of a quadratic, which is given by:

[tex]\displaystyle f(x)=a(x-h)^2+k[/tex]

Where (h, k) is the vertex.

Since we are given that the vertex is (8, -1), h = 8 and k = -1. Substitute:

[tex]f(x)=a(x-8)^2-1[/tex]

Next, we are given that the parabola passes through the point (-5, 9). So, when x = -5, y = 9:

[tex]9=a((-5)-8)^2-1[/tex]

Solve for a:

[tex]9=a(-13)^2-1[/tex]

So:

[tex]\displaystyle a=\frac{10}{169}[/tex]

So, the equation of our parabola is:

[tex]\displaystyle f(x)=\frac{10}{169}\left(x-8\right)^2-1[/tex]

Answer:

The equation of our parabola would be:

f(x) = 10/169(x - 8)[tex]^{2}[/tex] - 1

Step-by-step explanation:

Let cost of sandwich = s,  juice = j and salad = d.

2s + j = 500     (A)

s + d = 510       (B)

d + j =  530      (C)

Equation  (C) - (B)   ( to eliminate d):

j - s = 20          (D)

(A)  - (D) =   (to eliminate j):

2s - (-s) = 480

3s = 480

s = 160

A sandwich costs E 1.60.

unimodel: A unimodal distribution is a distribution with one clear peak or most frequent value. The values increase at first, rising to a single peak where they then decrease.

Answer:

the terms are 400n , 62n 120 and 8n

the number of coefficients is 3

equa expression  is 346n+120

Step-by-step explanation:1

Combining like terms 400n400n and -62n−62n

338n+120+8n

338n+120+8n

2 Combining like terms 338n338n and 8n8n

346n+120

346n+120

For the rest of them i just counted.

Answer:

Employee C

Step-by-step explanation:

A. We have to divide each earning by hour. Therefore, you have to do 180/15. Therefore, he makes 12 dollars per second.

B. We have to divide each earning by hour. Therefore, you have to do 210/20. Therefore, he makes 10.5 dollars per second.

C. We have to divide each earning by hour. Therefore, you have to do 455/35. Therefore, he makes 13.

This means that Employee C has the highest earning per hour.

Answer:

Naman is 12 years old

Step-by-step explanation:

This means his sister is 3 which means in 20 years Naman will be 32 and his sister will be 23. Double 23 and you get 46 and 46 - 32 is 14

Answer:

g=t-20

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

6 x 1/3 = 2

1/3 x (12-3) = 2 x 9

2 x 9 = 18

A = 2 (12/3) = 2 x 4 =  8

B = 2 x 15 = 30

C = 2 x 36 = 72

D = 2 x 9 = 18

Answer:

Sandwich - 2 $ and salad 3.10 $

Answer:

5

Step-by-step explanation:

U would have to multiply 3x10 that would equal 30 then you figure out how many '30s can fit into 6 that would equal 5

Answer:

2544 ft

Step-by-step explanation:

First, find the area of the pool.

A= πr²

if we fill in the radius, use 3.14 for pi, and solve for A, that's

A=(3.14)(20.5)²≈1319.585

The area of the pool is roughly 1319.585 ft

Now, we find the area of the triangle

A=(ab)÷2

put in 'a' and 'b' (the triangle legs) and solve

A=(84×92)÷2=3864

Finally, subtract the area of the pool from that of the triangle

3864-1319.585=2544.415 which rounds to 2544 ft

hopefully that helps and you might want to double check but that's what I got :)

Answer:

Step-by-step explanation:

it doesn't really say what the "face" is, but i'll guess that it's the part marked in yellow?  if that's the case then it's just  10 * 10  twice for each of the squares.  Really you couldn't see that?  :/      200 is the answer

Answer:

[tex]y= 2x - 3[/tex]

Step-by-step explanation:

rearrange equation into slope-intercept form

isolate y by subtracting x from both sides

[tex]2y=-x+14[/tex]

divide two from both sides

[tex]y= -\frac{1}{2}x+7[/tex]

here, we can note that the slope is -1/2, which to be perpendicular means it needs the negative inverse of slope

in other words, flip the fraction and take the negative of it, which gives m = 2

therefore plugging the given coordinates (6,9) and slope m = 2 into

[tex]y-y_{1} = m(x-x_{1} )[/tex]

therefore, we get

[tex]y-9=2}(x-6)[/tex]

distribute 2

[tex]y-9 = 2x - 12[/tex]

add 9 to both sides

[tex]y= 2x -3[/tex]

Answer:

y = 2x-3

Step-by-step explanation:

find the slope intercept first by isolation the y in the first equation

then because its asking for the perpendicular equation you will flip the x in the slope intercept equation.

now youll want to plug in (6,9) into y = 2x + a

and you will get -3

then youll have your answer

Answer: 26%

Step-by-step explanation:

20+52+34+71+23= 200

52/200 = 26/100

Answer:

26% of the jelly beans are yellow

Step-by-step explanation:

To find this we add up all the jelly beans which is 200 jelly beans

Then we divide it by the number of yellow jelly beans which is 52/200

which then equals .26. In a percentage that is 26%

Answer:

2

Step-by-step explanation:

The frequency is how many times the score shows up in the data set

21, 27, 20, 29, 23, 21, 21, 27, 26, 25

27 shows up 2 times so the frequency is 2

Answer: 2.357hrs

Step-by-step explanation:

Rate of dirt removal (rate) = 7/8 tons/hr

Total dirt removed (dirt) = 2 1/16 tons

Each hour, 7/8 tons of dirt will be removed, so if you work for h hours, you will have removed 7/8 * x tons of dirt. You can set up an equation as follows:

7/8 tons/hr * h hr = 2 1/16 tons (see how the units work out to give you tons)

Rearrange and solve for h:

h = (2 1/16) / (7/8) = 33/14 hrs = 2.357hrs

Answer:

1.  Square- a closed shape with 4 equal sides

2. Vertex- the highest point  

3. Line Polygon- A figure where all the sides are all line segments\

4. Quadrilateral- A shape with four sides

5. Area- When multiplying the length, width, and height of a shape

6. Perimeter- Adding up all the sides of the shape
