f(x) = x +4
g(x) = 3x^2 – 7
Find (f.g)(x)
Answer:
(f*g)(x) = 3x³+12x²-7x-28
Step-by-step explanation:
What (f*g)(x) means is that we multiply f(x) by g(x):
f(x) = x+4
g(x) = 3x²-7
(f*g)(x) = f(x)*g(x) = (x+4)(3x²-7) = (x)(3x²)+(x)(-7)+(4)(3x²)+(4)(-7) = 3x³-7x+12x²-28 = 3x³+12x²-7x-28

What does it mean to “solve” the following equation for y.
Holly buys a $22 shirt for 20% off. The tax rate in her city is 6.5%. What is the total amount she paid for the shirt? Round to the nearest cent.
Answer:
$18.74
Step-by-step explanation:
To find the sale price:
22 * 0.2 = 4.4
22 - 4.4 = 17.6
or, you can just multiply by 0.8, so you wont need to subtract later
22 * 0.8 = 17.6
Then, you need to find the tax amount:
17.6 * 6.5 = 1.144
17.6 + 1.144 = 18.744
Round
18.74
Please help i will give 100 points
First:
X = 15
Step-by-step explanation:
So the two angles are congruent, or they are the same angle. So you write the equation as 5x + 9 = 84.
5x + 9 = 84
-9 -9
5x = 75
(divide) 5 from both sides
x = 15
Second:
X = 27
Step-by-step explanation:
For this one I believe the answer is X = 27 because both equations should equal 180 degrees.
So you write the final equation:
(x + 72) + (3x) = 180
-72 -72
(combine X's):
4x = 108
Divide both sides by 4
X = 27
Third:
X = 40
Step-by-step explanation:
For this one, the angles match again, so you write it s:
4x - 50 = 2x + 30
+50 +50
4x = 2x +80
-2x -2x
2x = 80
Divide both sides by 2
X = 40
End

9514 1404 393
Answer:
a) 1.70 L
b) 16 breaths per minute
Step-by-step explanation:
a) The maximum value of v(t) occurs when the sine function is at its maximum value of 1. In that case, the volume is ...
1.27 +0.43×1 = 1.70 . . . liters
__
b) One full breath cycle takes a period of time that makes the argument of the sine function be 2π. The that time period is ...
1.71t = 2π
t = 2π/1.71 ≈ 3.6744 . . . seconds
Then the number of breaths per minute is ...
(60 seconds/minute)/(3.6744 seconds/breath) ≈ 16.33 breaths/minute
The person takes about 16 breaths per minute while sleeping.
Ms. Reynold's sprinkler system has 4 stations that water all parts of her front and back lawn. Each station
runs for an equal amount of time. If it takes 36 minutes for the first 3 stations to water, how long does it

minutes for Ms. Reynold to water her lawn.
Answer:
It will take 48 minutes to water all parts of her lawn.
Step-by-step explanation:
Each section runs for an equal amount of time
3 sections have run for 36 minutes
36 divided by 3 is 12, meaning each section runs for 12 minutes
12 times 4 is 48

A jewelry store is having a sale, and all items are 15% off. If a necklace was originally price at $85.00, what is the sale price?
Convert the equation − x − 2 y = 8 from standard to slope-intercept form
Answer:
y = -1/2x - 4
Step-by-step explanation:
We have our equation in standard form: -x - 2y = 8. We can use simplifying rules to isolate y on one side of the equation and give us our y = mx + b format. I'll begin by adding x to both sides.
-x - 2y = 8
-2y = x + 8
Now that we have y on one side, we can divide everything by -2.
-2y/-2 = x/-2 + 8/-2
y = -1/2x - 4
That looks like y = mx + b form.

Paul is shopping for laundry detergent. At the grocery store, the liquid detergent is pricedat $14.99 for 64 loads of laundry and the same brand of powder detergent is priced at$15.99 for 80 loads. Which is the better buy, the liquid or the powder detergent?
Answer:
15.99 is better
Step-by-step explanation:
because when working with dividing decimals we need to make it a whole number so we would move it over to the right till it is a whole number (which is two spaces) but first we need to put our decimal in our quotient so two spots. and 1499 divided by 64 equals 23.421875 and 1599 divided by 80 equals 19.9875 so the 15.99 dollar one is a better deal.
