**Answer:**

**Step-by-step explanation:**

4. A = P + Prt

a. Solve for r

Prt = P - A

r = (P - A)/Pt

b. Solve for t

Prt = P - A

t = (P - A)/Pr

5. Ax + By = C

a. By = C - Ax

y = (C - Ax)/B

b. Ax = C - By

x = (C - By)/A

6. y = mx + b

a. mx + b = y

mx = y - b

x = (y - b)/m

b. mx + b = y

mx = y - b

m= (y - b)/x

c. mx + b = y

b = y - mx

**Answer:**

**x = 0.3, y = 5.3, z = 17.3**

**Step-by-step explanation:**

Since given question is incomplete, so here is the complete table for the distance from the mean.

**Temp (°F) ** **29 38 45 31 50 58 62**

**Distance from the mean** 15.7 6.7 x 13.7 y 13.3 z

It's given that the **mean** of the data is **44.7**

Since distance from the mean of a data is the absolute value of the difference of data and mean,

Therefore, distance from the mean of the data will be,

**x = |**44.7 - 45| **= 0.3 (absolute value of the difference)**

**y =** |44.7 - 50| **= 5.3 **

**z =** |44.7 - 62|** = 17.3**

75 meters

189 meters

235 meters

Answer:I believe it would be answer choice, 235 meters

Step-by-step explanation:

I’m not super good at explain but, the height and incline both go at the right slope when they interact. Have a good day, hope it helps.

The **length** of the pyramid's **base** would be:

C). **235 meters**

Given that,

**Height **of the pyramid [tex]= 221[/tex]

**Elevation**/angle of the base [tex]= 62[/tex]°

Employing the **trigonometric** function,

Tan 62 [tex]= 221/[1/2 base][/tex]

⇒ **Base** [tex]= (2[/tex] × [tex]221)[/tex][tex]/Tan[/tex][tex]62[/tex]

[tex]= 2[/tex] × **221**/[tex]1.88[/tex]

[tex]= 235.10[/tex]

Substitute x and y in the equation

B. y=50x

If you look at the graph, you can see that in each dot the y equals to 50 Times x.

Such at the first dot, the location is at (1,50). 1*50=50

And at the second dot the location is at (2,100). 50*2=100

And at the last dot, the location is at (8,400). 8*50=400

If you look at the graph, you can see that in each dot the y equals to 50 Times x.

Such at the first dot, the location is at (1,50). 1*50=50

And at the second dot the location is at (2,100). 50*2=100

And at the last dot, the location is at (8,400). 8*50=400

2. Solve by substitution: y = -x + 2 AND 2x - y = -5*

**Answer:**

**Step-by-step explanation:**

y = -x + 2 -------(i)

2x - y = -5 -----------(ii)

Substitute y = -x + 2 in equation (ii)

2x - (-x + 2) = -5

2x + x - 2 = - 5

3x - 2 = -5 {add 2 to both side}

3x -2 + 2 = -5 + 2

3x = -3 { divide both sides by 3}

3x/3 = -3/3

**x = -1**

Plug in the value of x in equation (i)

y = - (-1) + 2

y = 1 +2

**y = 3**

What type of skew does this graph have?

**Answer:**

Negative skew; skewed right.

**Step-by-step explanation:**

It is a negative skew, because the peak of the graph is located towards the left (5- 9, respectively). The skewed is on the right, for the tail stretches out to the right of the graph (10-14 all the way to 25 - 29, respectively).

The angular velocity of a fan blade is 6.2 radians per second.

Approximately how many revolutions does the fan blade make in 1.6 minutes?

Enter your answer, rounded to the nearest tenth of a revolution

Answer:

94.7 revolutions

Step-by-step explanation:

In the question above, we are given the following values for the fan

Angular velocity = 6.2 radians per seconds

Time = 1.6 minutes.

Step 1

We would convert the time given to seconds

1 minute = 60 seconds

1.6 minutes = ?

We cross multiply

1.6 minutes × 60 seconds

= 96 seconds

Step 2

Number of revolutions made by the fan is calculated as :

Angular velocity(rad/s)

× time(seconds)

Number of revolutions = 6.2 radians per seconds × 96 seconds

=595.2 radians

Converting from radians to revolution

1 radian = 0.159155 revolutions

595.2 radians =

Cross multiply

= 595.2 radians × 0.159155 revolutions

= 94.729056 revolutions.

Approximately to the nearest tenth = 94.7 revolutions.

Therefore, the number of revolutions the fan blade makes in 1.6 minutes is 94.7 revolutions.

1.6 minutes is 1.6 x 60 = 96 seconds.

Its angular velocity is 6.2 radians per second: 6.2 radians/second x 96 seconds = 595.2 radians.

One revolution of the fan is one circumference of the fan, which is 2pi radians.

Dividing 595.2 radians by 2pi radians gives us an answer of 94.7 revolutions.

**Step-by-step explanation:**

A cylinder has a volume of 371.776 cubic centimeters. The diameter of the cylinder is 8 cm. What is the height of the cylinder? (Assume = 3.14)

Cylinder volume formula:

V=πr^2h

Substitute given values into the formula

Note: use 3.14 for pi

Diameter is twice the radius, so if diameter is 8 then radius is 4

371.776 = (3.14)(4^2)h

Use h for height because we don't know the height

Okay, so let's try to get the h by itself on the left side of the equation

So begin by getting rid of 3.14 by dividing it by both sides

371.776/3.14 = 118.4

3.14/3.14 = 1 (don't put 1, just remove the 3.14 from the right side)

So now we have:

118.4 = 4^2(h)

Now we can get rid of 4^2

Start by actually squaring it and then divide it from both sides

118.4 = 16(h) (4^2 = 16)

118.4/16 = 7.4

16/16 = 1 (dont put 1, just drop it)

So now we have

7.4 = h

Now we have h by itself! So h = 7.4

let's test it by putting it in the cylinder volume formula

V = πr^2h

371.776 = (3.14)(4^2)(7.4)

371.776 = (3.14)(16)(7.4)

371.776 = 50.24(7.4)

371.776 = 371.776

7.4 is your answer, if you have any questions, feel free to ask

A small TV that regularly sells for $89.00 is on sale at a 15% discount. What is the amount of discount?

**Answer:**

$13.35

**Step-by-step explanation:**

To find the amount of discount, multiply the discount rate by the usual price of the small TV.

discount rate * regular price

The discount rate is 15% and the regular price of the small TV is $89.00

15%*$89.00

15%*89

Convert 15% to a decimal by dividing 15 by 100, or moving the decimal place two spots to the left.

15/100=0.15

15.0-->1.5-->0.15

0.15*89

Multiply

13.35

The discount amount is **$13.35**

how would you differentiate this problem using the quotient rule?

rewrite the square root of X as X^ 1/2. Then take the derivative. Since 1/3 is a constant with respect to X you can pull that out. So, you should have

1/3 d/dx [ (2x^2-x^5)/3x^1/2].

Then factor x^2 out of 2x^2-x^5.

Then by using the negative exponent rule you should have

1/3 d/dx [ x^2(2-x^3)x^-1/2 ]

Then multiply x^2 by x ^-1/2 by adding the exponents.

1/3 d/dx [ x^3/2 (2-x^3)]

Then differentiate.

You should get x^1/2 - (3x^7/2)/2.

I hope that helps.

1/3 d/dx [ (2x^2-x^5)/3x^1/2].

Then factor x^2 out of 2x^2-x^5.

Then by using the negative exponent rule you should have

1/3 d/dx [ x^2(2-x^3)x^-1/2 ]

Then multiply x^2 by x ^-1/2 by adding the exponents.

1/3 d/dx [ x^3/2 (2-x^3)]

Then differentiate.

You should get x^1/2 - (3x^7/2)/2.

I hope that helps.
