Answer:

3/4 inch by 1/2 inch (length - width)

Step-by-step explanation:

If 1/2 inch equals 8 feet on the scale drawing, this means that 1/4 inch on the scale drawing equals 4 feet, by dividing 2 on both sides.

The storage shed is 12 feet long, and 4 feet on the scale drawing equal 1/4 inch. By multiplying the scale of 1/4 inch = 4 feet by 3 on both sides, we get 3/4 inch = 12 feet. This means that the length of the storage shed can be represented by 3/4 inch.

Since 1/2 inch equals 8 feet and the width of the storage shed is 8 feet, the width can be represented by 1/2 inch on the scale drawing.

The answer is 1, 2, 5, and 9

Relative to Stacy's goal, her average aerobics time over the last five weeks will be 0.09.

It is the average amount by which the function varied per unit throughout that time period. It is calculated using the gradient of the line linking the interval's ends on the graph depicting the function.

Stacy likes to do heart-stimulating exercises 10 hours every week to remain in shape. She tracks how much time she does heart-stimulating exercise every week compared with her goal. The table shows the information throughout the previous five weeks.

The table is given below.

Week                                          1              2            3              4            5

Aerobics time (hours)              2.8          −2           1 ³/₄          0           −3

Then relative to Stacy's goal, her average aerobics time over the last five weeks will be given as

⇒ (2.8 − 2 + 1 ³/₄ + 0 − 3) / 5

⇒ (0.45) / 5

⇒ 0.09

Relative to Stacy's goal, her average aerobics time over the last five weeks will be 0.09.

The area and the amount of gravel are illustrations of proportions.

7 lb will cover an area of 1 square foot, while 315 lb will cover an area of 45 square feet.

The given parameters are:

[tex]252\ lb= 36ft^2[/tex]

The number of pound for an area of 1 square foot is calculated as follows:

[tex]x = 1ft^2[/tex]

So, we have:

[tex]x = 1ft^2[/tex]

[tex]252\ lb= 36ft^2[/tex]

Cross multiply

[tex]x \times 36 = 252 \times 1[/tex]

Divide both sides by 36

[tex]x = 7lb[/tex]

The area to be covered with 315lb gravel is calculated as follows:

[tex]315lb = y[/tex]

So, we have:

[tex]315lb = y[/tex]

[tex]252\ lb= 36ft^2[/tex]

Cross multiply

[tex]y \times 252 = 36 \times 315[/tex]

[tex]y \times 252 = 11340[/tex]

Divide both sides by 252

[tex]y = 45[/tex]

Hence, 7 lb will cover an area of 1 square foot, while 315 lb will cover an area of 45 square feet.

E = 147°

F = 33°

Step-by-step explanation:

E:

E is 147°, because it is vertical to the angle 147°

F:

F is 33°, because 147* is its supplementary angle, or angles that add up to 180°

D:

D is worth 90°, because its supplement is worth 90°

Answer:

  A.  f(x) = x^2 -3x -10

Step-by-step explanation:

You can easily determine the correct equation by looking at a couple of table values.

The y-value for x=0 is -10, which is the constant in the quadratic formula. (eliminates choices B and C)

The y-value for x=1 is -12, which is the sum of coefficients in the quadratic formula. For choice A, the sum of coefficients is 1 -3 -10 = -12. For choice D, the sum of coefficients is 1 +3 -10 = -6. The value for choice D does not match the table, but the value for choice A does.

The function that represents the table is ...

  f(x) = x^2 -3x -10

_____

Additional comments

If you don't have equations to test, and you want to write your own equation, there are a couple of ways to do that. One is to look at the differences of y-values, and the differences of those.

The sequence of y-values shown is ...

  30, 18, 8, 0, -6, -10, -12

The sequence of differences of these numbers, starting with 18-30 = -12 is ...

  -12, -10, -8, -6, -4, -2

The sequence of differences of these numbers is ...

  2, 2, 2, 2, 2

The fact that they are constant tells you a quadratic (degree = 2) will describe the table.

We can find the coefficients a, b, c in the quadratic formula f(x) = ax^2 +bx +c as follows. First, we define d1 as the first of the sequence of differences (-12), and d2 as the value of the second differences (2). And we'll let x0 and y0 be defined as the first of the x-values (-5) and y-values (30).

The formulas for the coefficients (a, b, c) can be found from ...

  a = (d2)/2 = 2/2 = 1

  b = (d1) -a(2·(x0) +1) = -12 -1(2·(-5) +1) = -12 +9 = -3

  c = y0 -x0(a·x0 +b) = 30 -(-5)(1·(-5) +(-3) = 30 -40 = -10

As we noted above, the y-value corresponding to x=0 is also this c value. When the table includes x=0 and x=1, those can be used to simplify the finding of the formula coefficients.

These computations tell us f(x) = x^2 -3x -10, as above.

__

If you have to do this again, it might be useful to make a note of the expressions for 'a', 'b', and 'c' that we showed here, along with the definitions of the variables we used in them.

__

Another way to find the formula for f(x) is to make use of a calculator or spreadsheet capable of quadratic regression. Give it three (x, y) pairs from the table, and it can tell you the formula coefficients. This is illustrated by the attachment.

Answer:

C.8√3m or C.8(√3+1)m

Explanation:

The two points (0,0) and (2,1) are on the line. Apply the slope formula to them to get the following

m = (y2-y1)/(x2-x1)

m = (1-0)/(2-0)

m = 1/2

This indicates that each time you go up 1 unit, you must move to the right 2 units.

Slope = rise/run = 1/2

rise = 1, run = 2

Step-by-step explanation:

Because it tells you what y is

Answer:

Assuming its asking which is the easiest one to use substitution its the last one: y= 2x : x + y = 28

Step-by-step explanation:

Because y and x are already one opposite sides you can substitute y in the 2nd equation with 2x. So you'll get 3x = 28 so x = 9.333333334. Then you plug your answer for x in the original equation to get y = 18.666666667
