Answer:
k(w) = (w +3)²
Step-by-step explanation:
The name of the function is k, and its input is w, so the left side of the equal sign will be ...
k(w)
This is said to be the square of the sum w+3, so the right side of the equal sign will be ...
(w +3)²
The function equation in function notation is ...
k(w) = (w +3)²
Answer:
k(w) = (w +3)²

If the volume of cylinder of height 7 cm is 448 cm², then the total surface area of cylinder is
(1) 2041 cm?
(2) 2241 cm?
(3) 2481 cm?
(4) 240 cm?
Answer:
A = 240π cm²
Step-by-step explanation:
Given that,
Height of a cylinder, h = 7 cm
Volume of the cylinder, V = 448π cm³
We need to find the total surface area of the cylinder.
The formula for the volume of the cylinder is given by :
[tex]V=\pi r^2 h\\\\r=\sqrt{\dfrac{V\pi }{\pi h}} \\\\r=\sqrt{\dfrac{448\pi }{\pi \times 7}} \\\\r=8\ cm[/tex]
The formula for the total surface area of the cylinder is given by :
[tex]A=2\pi r(r+h)\\\\A=2\pi \times 8\times (8+7)\\\\A=240\pi \ cm^2[/tex]
So, the total surface area of the cylinder is 240π cm².
Hi can i pls get some help oh this question pls
its 5x - 2 = -7
Answer:
x= -1
Step-by-step explanation:
5x1 would be -5 then -5 - 2 would be -7
Answer:
x = -1
Step-by-step explanation:
The key thing to remember is that every operation you do on either side needs to be done on the other.
Let's start by getting rid of that -2 you can do that by adding 2 to both sides of the equals sign:
5x - 2 = -7
5x - 2 + 2 = -7 + 2
5x - 0 = -5
5x = -5
The next step is to get rid of that 5 on the left. We can do that by dividing both sides by 5:
5x = -5
5x ÷ 5 = -5 ÷ 5
x = -1
And there you have it! x is equal to negative one.

Answer:
The slope of line formed by given two points is undefined as the denominator becomes zero.
Step-by-step explanation:
Given points are:
(2,4) and (2,-2)
Here
[tex]x_1 = 2\\y_1 = 4\\x_2 = 2\\y_2= -2[/tex]
Slope is defined as the steepness of a line in the plane.
It is denoted by m and is given by the formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1}\\[/tex]
Putting the values we get
[tex]m = \frac{-2-4}{2-2}\\m = \frac{-6}{0}\\m = \infty[/tex]
The slope of line formed by given two points is undefined as the denominator becomes zero.
Lin is reading a 47-page book. She read the first 20 pages in 35 minutes. Rounding to the nearest minute, how long will it take Lin to finish the entire book?
Answer: 82.25 minutes
Step-by-step explanation:
First convert the minutes she took to hours. This would be:
= 35/60
She is reading at a speed of 20 pages per 35/60 hours.
To finish 47 pages therefore, she will take:
= (47 * 35/60) / 20
= 1.37083 hours
Converted to minutes that would be:
= 1.37083 * 60 mins
= 82.25 minutes

Answer:
UV=UZ+ZV
Step-by-step explanation:
UV=3y-5+2z+2
=3y+2y-3
but UV =27=3y+2y-3
30 =3y+2y
bisect means cut in to two equal parts so
3x+3=3y+6
3x-3y=6-3
3x-3y=3
then combine the two equation
30 =3y+2y this is 30=5y which is y=6
3 = 3x-3y so enter y=6 into this equation
3=3x-3*6
3=3x-18
3x=21

. Christian made $138,000 as a Physician Assistant. Social Security tax is to a maximum income of $128,400. The Medicare tax is 1.45% and the Social Security tax rate is 6.2%. How much did Christian pay in FICA taxes?
Answer:
Total money made as a physician = $138,000
Medicare tax = 1.45% of $138,000
= 1.45/100 * $138,000 = $2001
security tax = 6.2 %of $138,000
= 6.2/100 * $138,000 = $8556
= $138,000 - ($2001 + $8556)
$138,000 - $10557
= $127,443 is paid by Christian in FICA taxes
hope it helps you

The figure shows a line graph and two shaded triangles that are similar:
Which statement about the slope of the line is true?
Group of answer choices
A. It is fraction 1 over 2 throughout the line.
B. It is 2 throughout the line.
C.The slope from point O to point A is fraction 1 over 2 time the slope of the line from point A to point B.
D.The slope from point O to point A is two times the slope of the line from point A to point B.
Answer:
A
Step-by-step explanation:
You can use the formula change in y divided by change in x, so for this the change in y would be 2 and the change in x would be 4. This means the slope is 1/2.
In a line, the slope never changes so it's A.

The solution to the equation [tex]3^s[/tex] = 27 is s = 3.
To solve the equation [tex]3^s[/tex] = 27, we need to find the value of s that makes the equation true.
Since 27 can be written as 3³ (3 raised to the power of 3), we can rewrite the equation as:
[tex]3^s[/tex]= 3³
To solve for s, we can equate the exponents:
s = 3
Therefore, the solution to the equation [tex]3^s[/tex] = 27 is s = 3.

Answer:
C, The marble is 3 times as likely to be black as it is to be white.
Step-by-step explanation:
The probability of a marble being drawn is:
number of marbles of that color/total number of marbles
Find total number of marbles
5+8+4+15= 35
So the probability of drawing:
white: 5/32
polka dot: 8/32
striped: 4/32
black: 15/32
The probability of drawing white, polka dot, or striped is obviously different, so A is wrong.
The probability of drawing every color but black is 5/32 + 8/32 + 4/32 = 17/32, which is more than the chance of drawing black, so B is wrong.
The probability of drawing black is 15/32, and that is 3 times larger than the probability of drawing white (5/32), so C is correct.
The probablility of drawing a polka dot is 8/32, which is not four times as large as stripe (4/32), so D is wrong.
