Answer:

Step-by-step explanation:

I'm assuming the 7 is the question number.

The cube root is -2. There is only 1 real root.

You could find it this way. ∛(-8) = ∛-2 * - 2 * - 2

The rule for cube roots when the number has 3 roots that are the same is to take one outside the ∛ sign and discard the other 2.

-2 ∛1 The cube root of one is one.

Answer:

y = 1566.67x + 1716.67

is the actual answer..

The linear equation that can be used to approximate the data distribution is y = 1566.67x + 1716.67.

Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.

Linear equations may include one or more variables.

Given two points on the line.

(0.5, 2500) and (3.5, 7200)

Slope intercept form of a linear equation is y = mx + c, where m is the slope and c is the y intercept.

Slope = (7200 - 2500) / (3.5 - 0.5)

          = 4700 / 3

          = 1566.67

So the equation is, y = 1566.67x + c

Substitute the point (0.5, 2500) to the equation.

2500 = (1566.67 × 0.5) + c

c = 1716.67

So the equation is, y = 1566.67x + 1716.67

Hence the required equation is y = 1566.67x + 1716.67.

The number of people by the year 2050 is obtained as 927915 people.

We know that population is an exponential growth problem in this case. We have to apply the formula;

P = Poe^rt

P = population at time t

Po = Initial population

r = population growth rate

t = time taken

Now;

We have to use the relation to find the growth rate as follows;

733,000 = 622,000 e^20r

733,000/622,000 = e^20r

1.178 = e^20r

ln(1.178) = 20r

r = ln(1.178)/20

r = 0.008

Now;

In the year 2050, we would have;

P = 622,000 e^50 * 0.008

P = 927915 people

Answer:

Triangle - 17.5

Trapezoid - 64

Step-by-step explanation:

Triangle  - This is because the triangle formula is h x b/2 and H is 7 and B is 5 so 5 x 7 is 35 divided by 2 is 17.5.

Trapezoid - a + b/2 times h and A is 6, B is 10 and H is 8 so 6+10 = 16 and 16/2 equals 8 and 8 x 8 =64.

Using it's concept, it is found that the probability that the card is a diamond or a face card is given by:

D. 25/52

A probability is given by the number of desired outcomes divided by the number of total outcomes.

A standard deck has 52 cards, of which 13 are diamond and 12 are face, hence:

p = (13 + 12)/52 = 25/52.

Which means that option D(25/52) is correct.

Step-by-step explanation:

Answer:

100.32

Step-by-step explanation:

First, we have to find 14% of 88
14% of 88 is = 88 x 14/100
                   = 12.32

Now we have to increase the number 88 by 14%, which means we have to add 14% of 88 (12.32) to the given number (88)  

88 + (14% of 88)

= 88 + 12.32

=100.32

Answer:

88 ft

Step-by-step explanation:

The wedge is an illustration of arc lengths, and Tyler's ledge is larger than Priya's wedge

From the question, the arc length of Tyler's wedge is:

L = 12 cm

For Priya's wedge, we have the following highlights:

Radius = 9 cm

Angle = 60 degrees i.e. the angle when a circle is divided into 6 sectors

Priya's arc length is then calculated as:

[tex]L = \frac{\theta}{360} * 2\pi r[/tex]

This gives

[tex]L = \frac{60}{360} * 2 * 3.14 * 9[/tex]

Evaluate

L = 9.42

By comparing the arc lengths 9.42 and 12 cm, we have 12 cm > 9.42 cm

Hence, Tyler's ledge is larger than Priya's wedge

Answer:

Answer is equation C

Step-by-step explanation:

They are converting Celsius temperature to Fahrenheit temperature.

F = 1.8C + 32

F = 1.8(0) + 32 = 32 Fahrenheit

F = 1.8(30) + 32 = 86 Fahrenheit

F = 1.8(100) + 32 = 212 Fahrenheit

Answer:

C) F = 1.8C + 32

Step-by-step explanation:

Hello! The easiest way to do this is to substitute the numbers from your table into your possible answer choices until you find numbers that make a true/correct statement.

For A:

F = 32C + 1.8 <== substitute any number for F and C from your table

32 = 32(0) + 1.8 <== multiply

32 = 0 + 1.8 <== add

32 = 1.8

This statement is false/incorrect

For B:

C = 1.8F + 32 <== substitute any number for F and C from your table

0 = 1.8(32) + 32 <== multiply

0 = 57.6 + 32

0 = 89.6

This statement is false/incorrect

For C:

F = 1.8C + 32 <== substitute any number for F and C from your table

32 = 1.8(0) + 32 <== multiply

32 = 0 + 32 <== add

32 = 32

This statement is true/correct

For D:

C = 32F + 1.8 <== substitute any number for F and C from your table

0 = 32(32) + 1.8 <== multiply

0 = 1024 + 1.8 <== add

0 = 1025.8

This statement is false/incorrect

As we can see, the only equation that makes a true statement is C.

Therefore, the correct answer is C.

Answer:

First you need to find the slope:  (y2 - y1)/(x2 -x1) = (-4 -(-4))/(0-2) = 0.  So the line is horizontal, which means the y coordinate is constant and equal to -4, so the equation of the line is y = -4.

Step-by-step explanation:

since both points have a y value of -4 you could have jumped directly to y = -4
