a parabolic lamp is facing due east. The bulb (located at the focus) is 8 inches away from the vertex (located at the origin). the lamp has a diameter of 20 inches. Which is the depth of the dish?

Answers

9514 1404 393

Answer:

3 1/8 inches

Step-by-step explanation:

For focus-vertex distance p, the equation of the parabola can be written ...

y = x^2/(4p)

Here, we have p=8. We want to find the value of y when x=10 (the radius of the dish). That is ...

y = (10^2)/(4·8) = 100/32 = 3 1/8

The dish is 3 1/8 inches deep.

solve the equation 7- 14m = 2m - 5

Answers

Answer:

m = 6/7

Step-by-step explanation:

Rearrange the equation so that like terms are on either side

7 + 5 = 2m + 14m

12 = 14m

Divide both sides by 14 so that the variable is on its own

12/14 = m

m = 6/7

Sharon drove 270 miles in 4.5 hours. If she drove at a constant rate, how fast was Sharon driving?

Answers

Answer:

Sharon was driving 60 miles per hour.

Step-by-step explanation:

To solve this you must divide both the amount of miles (270) and the amount of hours (4.5) by the amount of hours so that way you can see how many miles per hour you are going.

4.5 / 4.5 = 1

270 / 4.5 = 60

This means that Sharon was driving 60 miles per hour.

Grace wants to frame a square picture which has a area of

950 square inches.

How long is each side of the picture?

She has another square picture with an area of 1200 square inches.
How long is each side of this picture?

Answers

Answer:

First Picture: Length = 30.82in

Second Picture: Length = 34.64in

Step-by-step explanation:

Given

Picture 1:

Area = 950in²

Picture 2:

Area = 1200in²

Required

Determine the length of each pictures

From the question, we understand that both pictures are square in shape and the area is calculated as thus:

Area = Length²

For the first picture, substitute 950 for Area

This gives:

950 = Length²

Length ² = 950

Take square root of both sides

Length = √950

Length = 30.8220700148448822

Length = 30.82 (approximated)

Hence, the length of the first picture is 30.82in

For the second picture, substitute 1200 for Area

This gives:

1200 = Length²

Length² = 1200

Take square root of both sides

Length = √1200

Length = 34.6410161513775458

Length = 34.64 (approximated)

Hence, the length of the second picture is 34.64in

Ricky and Sam each bought a remote control car for $80. A few months later they both sold it. Ricky sold his car for 25% less than the original price and Sam sold his car for 30% less than the original price. How much more did Ricky get than Sam?

Answers

Answer:

Step-by-step explanation:

Answers

Answer:

Step-by-step explanation:

2-digit number: 10x + y

y = x + 4

20x + 2y = 10y + x + 1

Answers

The equation of this line in slope intercept form is y = 1.5x + 13.

What is slope intercept form?

The slope-intercept form of a straight line is used to find the equation of a line. For the slope-intercept formula, we have to know the slope of the line and the intercept cut by the line with the y-axis.

Equation of line: y = mx + c

where m is slope of line and c is the y intercept.
