Answer:

g(2)=2

Step-by-step explanation:

g(x)=x2-x

First you have to substitute.

g(2)=2(2)-2

Now just solve.

g(2)=2

<h3>Answer: 2</h3>

Work Shown:

g(x) = x^2 - x

g(2) = 2^2 - 2 ... replace every x with 2

g(2) = 4 - 2

g(2) = 2

In this case, we won't use f(x)

what is the vertical height of interverted cone with the diameter of 6 cm and the slant height of 6cm?

den301095 [7]

"interverted" or "inverted?"

The vertical height of an inverted cone with base diameter 6 cm and slant height of 6 cm can be found using the Pyth. Thm. Draw or imagine a triangle whose height is h and whose base is 3 cm (not 6) and whose hypotenuse is 6 cm.

Then h^2 + (3 cm)^2 = (6 cm)^2, or h^2 + 9 cm^2 = 36 cm^2, or h^2 = 27 cm^2.

Then the height of the triangle, as well as of the cone, is h = +√27, or

h = +3√3.

Answer:

141.5 in

Step-by-step explanation

AB // CD // EF

12 / 15 = 21 / y (By the property of 3 parallel lines and its transversals)

y = (15*21) / 12 = 26.25

CD // EF // GH

21 / y = x / 10 21 / 26.25 = x / 10

x = (21*10) / 26.25

x = 8

perimeter of ABHG = (y-14) +15 + y + 10 + (5x-3) + x + 21 + 12 = 141.5

Answer:

2.20752 x $10^{24}$

Step-by-step explanation:

The first thing you have to do is to look for the number of seconds in one year. You have to multiply 365 days by 86,400 seconds.

365 days refer to the total number of days per year
86,400 seconds refer to the number of seconds per day

Let's solve.

365 x 86,400 = 31,536,000 or 3.1536 x $10^{7}$

<em>Therefore, one year has 3.1536 x </em> $10^{7}$ <em> seconds.</em>

Next, you have to know the number of seconds in 10 billion years.

(3.1536 x $10^{7}$ ) x (1.0 x $10^{10}$ ) = 3.1536 x $10^{17}$

The last step is to multiply the number of seconds in 10 billion years to 7 million tons of mass per second.

(3.1536 x $10^{17}$ ) x 7,000,000 = 2.20752 x $10^{24}$

Masco Industries has 285,000 total employees. Of those employees, 85,500 telecommute. What percent of the company’s total employ

frosja888 [35]

Answer:

30% of the company’s total employees telecommute

Step-by-step explanation:

Masco Industries has 285,000 total employees. Of those employees, 85,500 telecommute.

To find the percentage of company’s total employees telecommute

We divide the number of employees telecommute by total employees

Then we multiply by 100 to get percentage

Percentage = $\frac{number \ of \ telecommute \ employess}{total \ employees} * 100$

Percentage = $\frac{85500}{285000} * 100$

Percentage = 0.3 * 100 = 30%
