Can someone please help me on this

Step-by-step explanation:

3√(x - 4) + 7 = -14

3√(x - 4) = -21 (subtract 7 from both sides)

√(x - 4) = -7 (divide 3 on both sides)

However √y is non-negative for all values of y in the domain of √y.

Hence there is no real solution for x.

Answer:

7 pounds

Step-by-step explanation:

From the graph :

The data model:

X:

10

20

30

40

50

Y:

2

3

4

5

6

Using a linear regression calculator :

The equation of best fit for the data is :

y = 0.1x + 1

Weight loss for someone who attended 60 fitness classes :

Using the model:

y = 0.1x + 1

Where x = 60

y = 0.1(60) + 1

y = 6 + 1

y = 7

Divide 360 by the amount of the exterior angle to also find the number of sides of the polygon.

Step-by-step explanation:

360/2 = 180

therfore it has 180 sides

Answer:

Step-by-step explanation:

Geometric series with first term 3 and common ratio r.

Last variety = 3 * 2^(12-1) = 6144.

Total =  3 * (2^12 - 1) / (2-1)

= 12285

Answer:

I(20) is 600 dollars

Step-by-step explanation:

From the given function, I(p) = p(50 - p)

Where I is the income in dollars and p is price dollars.

To determine I(20), that is, to determine the income in dollars when the ticket price is 20 dollars.

From

I(p) = p(50 - p)

When p = 20

Then,

I(20) = 20(50 - 20)

I(20) = 20(30)

I(20) = 20 × 30

I(20) = 600

Hence, I(20) is 600 dollars

That is, the income is 600 dollars when the ticket price is 20 dollars.

The answer is

x ≤ -3  

Answer:

[tex]9\pi \: \mathrm{ft^2\:or}\: 28.27 \mathrm{\: ft^2}[/tex]

Step-by-step explanation:

The area of a circle is given by [tex]r^2\pi[/tex] where [tex]r[/tex] is the radius of the circle. The diameter is given as [tex]6[/tex] feet, so the radius of this circle is [tex]\frac{6}{2}=3[/tex] feet.

Plugging in our values, we get:

[tex]3^2\pi=9\pi\approx28.27[/tex].

Answer:

Answer:

1 1/2

Step-by-step explanation:

set up a proportion:

8 = 12

1        x

cross-multiply:  8x = 12

                          x = 12/8

                          x = 3/2 (simplified)

Answer:

The number of children = x = 176

The number of Adults = y = 87

Step-by-step explanation:

Let us represent

The number of children = x

The number of Adults = y

On a certain hot summer's day, 263 people used the public swimming pool.

x + y = 263.... Equation 1

x = 263 - y

The daily prices are $1.25 for children and $2.50 for adults. The receipts for admission totaled $437.50.

$1.25 × x + $2.50 × y = $437.50

1.25x + 2.50y = 437.50.....Equation 2

We substitute 263 - y for x in Equation 2

1.25(263 - y) + 2.50y = 437.50

328.75 - 1.25y + 2.50y = 437.50

- 1.25y + 2.50y = 437.50 - 328.75

1.25y = 108.75

y = 108.75 ÷ 1.25

y = 87

Solving for x

x = 263 - y

x = 263 - 87

x = 176

Therefore:

The number of children = x = 176

The number of Adults = y = 87

Answer:

the answer is approximately 8.2 units.

Answer:

9) 30 years

10) line passing through points AB and BC are perpendicular

Step-by-step explanation:

9) p = 5t + 150    

Current pop. (in thousands) is 150

Double pop. (in thousands) is 300

300 = 5t + 150

150 = 5t

t = 30

10) line passing through points AB and BC are perpendicular because their slopes are opposite and reciprocal

slope of AB = 3

slope of BC = -1/3

Answer:

the first one

Step-by-step explanation:

Answer:

The first graph

Step-by-step explanation:

1.) The line has to go down since it's a negative slope so looking at these 3 graphs it cant be the second one, since it has a positive slope

2.) The y-intercept has to be 4, but for the 3rd image it is 3 which is incorrect

3.) The first graph has a slope of -2/3, and a y-intercept of 4 which makes it....

y = -2/3x + 4...and this one is correct

Hope this helped!

Answer:

1.475 × 10¹⁴ mi

Step-by-step explanation:

Since  1 light year = 5.9 × 10⁹ mi and the Earth is located about 25,000 light-years from the Milky Way's rim, the approximate distance, in miles, from Earth to the rim of the Milky Way is 25,000 light year = 25,000 × 1 light year

= 25,000 × 5.9 × 10⁹ mi

= 147.5 × 10¹² mi

= 1.475 × 10¹⁴ mi
