Answer:

k = 9

Step-by-step explanation:

For this, we can factor the top expression to look like the bottom expression.

So, first we have to find the gcf of 18 and $x^{2}$ and add up to 11x.

18 $x^{2}$ 11x

1 and 18 19 - No

2 and 9 11 - Yes

3 and 6 9 - No

So, the numbers are 2 and 9. The expression should now look like this:

$x^{2}$ + 2x + 9x + 18

Now, undistribute the terms.

x(x + 2) + 9(x + 2)

(x+2)(x+9)

This matches up with the bottom expression.

The value of k is 9.

Find the measurement of Angle SPQ

Harrizon [31]

Answer:

146 °

Step-by-step explanation:

sum of angles in circle = 360°

360 - 154-60-86 = 60

60 = UPS

SPQ = UPS + QUP = 60 + 86 = 146°

Suppose the diameter of a circle is 4. What is its radius? and please explain

Olin [163]

The radius of a circle is always half of the diameter of the circle. In this case, the diameter is $4$ , meaning that when we halve $4$ , we will get our radius. Therefore, the radius of the circle is $\boxed{2}$ . Hope this has helped you understand and have a great day!

PLZZZZZ HELP MEH ILLLL MARK AND 100 points

Nataliya [291]

Answer:

Volume of original toolbox = 180 in³

Yes, doubling one dimension only would double the volume of the toolbox.

Step-by-step explanation:

Volume = L x W x H

10 x 6 x 3 = 180 in³

proof:

double length = 20 x 6 x 3 = 360 in³, which is double the original

double width = 10 x 12 x 3 = 360 in³, which is double the original

double height = 10 x 6 x 6 = 360 in³, which is double the original

Values of the composite function:

$(g\cdot f)(-1)=6$

$(g\cdot f)(0)=7$

$(f\cdot g)(-1)=3$

$(f\cdot g)(4)=2$

Step-by-step explanation:

Given two functions f(x) and g(x), their composite function is given by

$(f\cdot g)(x) = f(g(x))$

Which means using the output value of g(x) as input for f(x).

Let's start by computing

$(g\cdot f)(-1)$

First, we compute the value of f(-1), which is (from the graph)

f(-1) = 1

Now we use this value as input into g(x); we notice that at x = 1, the value of g(x) is 6, therefore:

$(g\cdot f)(-1)=6$

Now we evaluate

$(g\cdot f)(0)$

First, we compute the value of f(0), which is (from the graph)

f(0) = 0

Now we use this value as input into g(x); at x = 0, the value of g(x) is 7, therefore:

$(g\cdot f)(0)=7$

Now we evaluate

$(f\cdot g)(-1)$

First, we compute the value of g(-1), which is (from the graph)

g(-1) = 5

Now we use this value as input into f(x); at x = 5, the value of f(x) is 3, therefore:

$(f\cdot g)(-1)=3$

Finally we evaluate

$(f\cdot g)(4)$

First, we compute the value of g(4), which is (from the graph)

g(4) = 4

Now we use this value as input into f(x); at x = 4, the value of f(x) is 2, therefore:

$(f\cdot g)(4)=2$

Liwen and Celina shared some plants in a ratio of 5:6. Celina decided to give Liwen 2/3 of her plants, which left her with 21 fe

djyliett [7]

Answer: 231

<u>Explanation:</u>

Liwen Celina

5x 6x

5x - 21 = $(\frac{2}{3})$ 6x

5x - 21 = 4x

<u>-4x +21</u> <u>-4x +21 </u>

x = 21

Liwen: 5x = 5(21) = 105

Celina: 6x = 6(21) =<u> 126</u>

Total: 231
