Let f(x) = 3x + 2 and g(x) = - 2x + 1 Find g(f(- 2))

is it
a: -7
b: 17
c: 0
d:9​

Answers

Answer 1

Answer:

(d) 9

Step-by-step explanation:

f(x) = 3x + 2

g(x) = - 2x + 1

g(f(x)) = - 2(3x + 2) + 1 = - 6x - 4 + 1 = - 6x - 3

g(f(-2)) = - 6(- 2) - 3 = 9

It should be x^4/7 (the first option). When you multiply square roots, you can convert them into x to the root of whatever the numbers are. An example would be the square root of x. You can convert that to x^1/2. The root on the outside is the denominator and the exponent on the inside is the numerator. For this one, you'd convert it to x^1/7. Then, you'd add all of the exponents up. 1/7 + 1/7 + 1/7 + 1/7 = 4/7. If you wanted to convert it back to a root form, it'd be ^7√x^4, but since there's no option for that, it'd be x^4/7

He needs to buy 3.6 spools but I guess that wouldn't be possible in real life so he needs to get 4 and then has some leftover.

Anjelica is using synthetic division to divide 2x3−9x2−21x+10 by x+2 .



Which answer is correct?

Answers

Answer:

B I the answer I just did the same question

Anjelica is using synthetic division to divide

[tex]\:\frac{\left(2x^3-9x^2-21x+10\right)}{x+2}[/tex]

Steps given in option B are correct

Given :

Divide the given expression

[tex]\:\frac{\left(2x^3-9x^2-21x+10\right)}{x+2}[/tex]

Apply synthetic division

In synthetic division , we write all the coefficient inside the division

then solve the denominator for x  and write it outside

[tex]x+2=0\\x=-2[/tex]

so we write -2 outside the division sign

Take down first number 2 as it is . Then multiply with -2  and put it below the second number . Add it and write it down . Continue the process.

-2              2       -9      -21    10

5. €1575 was shared among three people in the ratio 1:2:1/2

Calculate the smallest share.

Answers

Answer:

€225

Step-by-step explanation:

Given that:

1575 shared in the ratio 1 : 2 : 1/2

Total sum of ratio = (1 + 2 + 1/2) = 3 1/2

Ratio 1 amount :

(1 / 3.5) * 1575 = 450

Ratio 2 amount :

(2 / 3.5) * 1575 = 900

Ratio 1/2 amount :

(1/2 ÷ 3.5) * 1575 = 225

Smallest share = $225

a grid of a hundred square show 7 shaded squares what decimal number is represented​

Answers

Answer:

0.07

Step-by-step explanation:

From the question, a given grid was divided into a definite number of squares with some of the squares shaded.

Total number of squares in the grid = 100

number of shaded squares in the grid = 7

Thus, 7 squares are shaded out of 100 square in the grid.

So that this can be expressed in fraction as;

[tex]\frac{number of shaded squares}{total number of squares}[/tex] = [tex]\frac{7}{100}[/tex]

                                = 0.07

The decimal number of the squares represented is 0.07.

At the time this question was written, one US Dollar equaled 0.88 Euros. What would 50 Euros equal in US Dollars? Round your answer to the nearest cent.

Answers

Answer:

$56.82 US dollars

Step-by-step explanation:

Set up a proportion where x is how many US dollars there are in 50 Euros:

[tex]\frac{1}{0.88}[/tex] = [tex]\frac{x}{50}[/tex]

Cross multiply and solve for x:

0.88x = 50

x = 56.82

So, 50 Euros is approximately equal to $56.82 US dollars

The part of a cylindrical soup can that is covered by the label is 8.5 cm tall and has a diameter of 6.5 cm. What is the area of a label that covers the entire side of the can and that need a 0.8-cm overlap to glue the ends of the label? Round to the nearest tenth.

Answers

Answer:

[tex]180.4~cm^2[/tex]

Step-by-step explanation:

Surface Area

The surface area of a cylinder of height h and radius r is given by:

[tex]A=2\pi rh[/tex]

It only covers the lateral side of the cylinder. If both the top and the bottom sides are to be included, then:

[tex]A=2\pi rh+2\pi r^2[/tex]

The label will cover only the lateral side of the soup can that has a height of h=8.5 cm and a diameter of 6.5 cm. We need to calculate the radius which is half of the diameter r=6.5 cm / 2 = 3.25 cm.

Now we calculate the side area of the can:

[tex]A=2\pi (3.25)(8.5)[/tex]

[tex]A=173.6~cm^2[/tex]

We need to add the 0.8 cm overlap to the total area already calculated. This overlap has 0.8 cm of width and 8.5 cm of height, so this overlap area is:

[tex]A_o= 0.8*8.5=6.8~cm^2[/tex]

The total area of the label is:

[tex]A=173.6~cm^2+6.8~cm^2=180.4~cm^2[/tex]

The area of the label is [tex]\mathbf{180.4~cm^2}[/tex]

A circle has a radius of 13cm . Find the radian measure of the central angle 0 that intercepts an arc of length8cm . Do not round any intermediate computations, and round your answer to the nearest tenth.

Answers

Answer:

The measure of the center angle is 0.6 radians

Step-by-step explanation:

Mathematically, the length of an arc can be calculated using;

L = theta/360 * 2 * pi * r

where theta is the central angle

In this case, theta = ? , pi = 22/7 and r is 13

cm, length of arc is 8 cm

So we have ;

8 = theta/360 * 2 * pi * 13

360 * 7 * 8 = theta * 2 * 22 * 13

20,160 = 572 theta

theta = 20,160/572

theta = 35.24

let us convert this to radian measure

Mathematically, 1 degree = 0.0175 radian

Thus 35.24 degrees will be 35.24 * 0.0175 = 0.62 radians

To the nearest tenth, this is 0.6 radians
