ez pts someebody help find the equation axis of symmetry of y=-2(x-3)^2 +4

Answers

Answer:

x = 3

Step-by-step explanation:

Given function:

y= -2(x-3)² +4

Vertex form:

y = a(x − h)² + k

Axis of symmetry is the line parallel to y-axis and passes through vertex. The x-coordinate of the vertex is determined by the value of h in the above equation.

We have h = 3 as per given equation for the function.

Axis of symmetry is the line x = 3

The ratio of a model car to a regular car is 1:16. The model is 6.25 inches long. What is the length of the actual car in feet and inches? what if the ratio of the model car was 2:35, then what would be the actual length of the car?

Answers

Answer:

Step-by-step explanation:

model car 1 : regular car 16

model 6.25 inches : actual car 6.25*16 = 100 inches

1foot = 12 inches

100/12 = 8 feet and 4 inches

model car 2 : regular car 35

model 6.25 inches : actual car 6.25*35/2 = 109. 375 inches

Answer:

s = 17t = 5

Step-by-step explanation:

The midpoint formula is useful here. For midpoint M, we have ...

  M = (C + D)/2

  2M = C + D

  2(10, 10) = (15, s) +(t, 3)

  (20, 20) = (15+t, s+3)

  t = 20 -15 = 5

  s = 20 -3 = 17

__

Check

  (C +D)/2 = ((15, 17) +(5, 3))/2 = (20, 20)/2 = (10, 10) . . . checks OK

MARKING YOU BRAINLIST AND 5 STARS! A tire from Karen's car is shown below. Which is the closest to the distance traveled, in feet, after 3 full rotations of the tire? The diameter is 2 feet, by the way.

Answers

Answer:

18.86 feet

Step-by-step explanation:

One rotation of the tire is equal to the circumference of the tire

The formula for circumference of a circle (remember that a tire is shaped as a circle) = πd

where

π = 22/7

d = diameter

The size of one revolution = 2 x 22/7 = 44/7 feet

The distance covered in one rotation of the tire is 44/7 feet

The distance covered in 3 rotations = (44/7) x 3 = 18.86 feet

The value of a piece of land deprecates at a rate of 0.60 per year after three years land is worth 2500 what was the original value of the building

Answers

Well, there is actually a formula for this kind of exercises:

n is the price the land had in the third year year

2500=n-nx0.6

2500=n(1-0.6)

2500=nx0.4

n=2500:0.4

n=6250

m is the price the land had in the second year

6250=m-mx0.6

6250=m(1-0.6)

6250=nx0.4

p=6250:0.4

p=15625

p is the price the land had in the first year

15625=p-px0.6

15625=p(1-0.6)

15625=px0.4

p=15625:0.4

p=39,062.5 <- this should be your answer. Hope this helps.

laura has 160 pounds of green beans at her vegetable stand. she sells 10 pounds of green beans every hour, what is the percent decrease in green beans after 3 hours?​

Answers

Answer:

18.75%

Step-by-step explanation:

Green beans = 160 pounds

Amount sold in 1 hour = 10 pounds

Amount sold in 3 hours = 3x10= 30 pounds

Decrease in 3 hours = 30 pounds

% decrease = (30/160) x 100

=300/16

=75/4

=18.75%
