The function f(x) = 2x2 + 3 represents the rate of a boat traveling with the current in miles per hour. The function g(x) = x + 2 represents the time the boat traveled in hours. Solve (f • g)(2), and interpret the answer.
(f • g)(2) = 15, the distance in miles the boat traveled
(f • g)(2) = 15, the number of boats
(f • g)(2) = 44, the distance in miles the boat traveled
(f • g)(2) = 44, the number of boats
Answer:
C. (f • g)(2) = 44, the distance in miles the boat traveledStep-by-step explanation:
Given functions:
f(x) = 2x² + 3g(x) = x + 2Find the value of (f · g)(2):
(f · g)(2) = f(2) · g(2) = (2(2²) + 3) · (2 + 2) = 11 · 4 = 44Since this is a product of the speed and the time, this represents the distance travelled in 2 hours
Correct choice is C
Find f.g(x)
(x+2)(2x²+3)2x³+3x+4x²+6Put 2
f.g(2)
2(2)³+3(2)+4(2)²+62(8)+6+6+4(4)16+16+1244Option C

Answer:
1130.4 m^3
Step-by-step explanation:
For top cone:
radius r = 6 m
height [tex]h_1 = 12\:m[/tex]
For down cone:
radius r = 6 m
height [tex]h_2 = 18\:m[/tex]
[tex]V_{solid} = V_{top\: cone}+V_{down\: cone} \\ \\ = \frac{1}{3}\pi r^{2} h_{1} + \frac{1}{3}\pi r^{2} h_{2} \\ \\ = \frac{1}{3} \pi {r}^{2} ( h_{1} + h_{2}) \\ \\ = \frac{1}{3} \pi {(6)}^{2} (12 + 18) \\ \\ = 12\pi(30) \\ \\ = 360(3.14) \\ \\ = 1130.4 \: {m}^{3} [/tex]

Some students mowed 12 lawns in 3 hours. How many lawns can they mow in 18 hours? 4 lawns 36 lawns 72 lawns 216 lawns.
Answer:
72 lawns
Step-by-step explanation:
if the students could mow 12 lawns in 3 hours, then we can turn it into a ratio of 12:3, which we can simplify to 4:1.
to find how many lawns they can mow in 18 hours, we can multiply the numbers in our ratio by 18.
4x18=72
1x18=18
our new ratio is 72:18
we can translate this to:
they can mow 72 lawns in 18 hours

using A map with a scale of 2 centimeters equal to 1 mile, Marcos measures the distance to his grandfathers house at 11 centimeters. Copy and complete the ratio table below to find the distance to Marco's grandfathers house.
Answer:
his grandfathers house is 5.5 miles away
Step-by-step explanation:
2 centimeters = 1 mile
1 centimeter = 1/2 mile
distance to grandfathers house is 11 centimeters
11/2= 5.5
his grandfathers house is 5.5 miles away.
2cm = 1 mile
3cm = 1.5 miles
4cm = 2 miles
5cm = 2.5 miles
6cm = 3 miles
7cm = 3.5mile
8cm = 4 miles
9cm = 4.5 miles

The list of numbers 41, 35, 30, X, Y, 15 has a median of 25. The mode of the list of numbers is 15. To the nearest whole number, what is the mean of the list?
A.20
B.25
C.26
D.27
E.30
Answer:
C) 26
Step-by-step explanation:
41 , 35,30 , X , Y ,15
Number of data's = 6. So, median will be the average of [tex](\dfrac{6}{2})^{th} \ and \ (\dfrac{6}{2}+1)^{th} \ term[/tex] . 3 and 4th term
Median = [tex]\dfrac{30+X}{2}[/tex]
[tex]\dfrac{30+X}{2}=25\\\\[/tex]
30 + X = 25*2
30 + X = 50
X = 50 - 30
X = 20
Mode is 15
So, Y = 15

The weight of an object on the moon is 1/6 of its weight on earth. If a moon rock weighs 20 1/2 lb on earth, how much did the rock weigh on the moon. Simplify your answer
Step-by-step explanation:
20 1/2 = (20×2 + 1)/2 = 41/2.
to create 1/6 of that we have to multiply it by 1/6 :
41/2 × 1/6 = 41/12 = 3 5/12
the rock weighed 3 5/12 lb.
the rational number halfway between 2/3 and 5/6
Step-by-step explanation:
Answer:
3/4
Step-by-step explanation:
Will make those 2 fractions have the same denominator by finding an equivalent fraction for 2/3
2/3 = 2*2/ 2*3 = 4/6
Half way between 4/6 and 5/6 is 4.5 /6
4.5/6 if we double it is the same as 9/12
9/12 = 3*3/ 3*4 = 3/4 is simplified 4.5/6 or 9/12
The rational number halfway between 2/3 and 5/6 is 3/4
Anthony, Brad, and Chase have a combined age of 106. Anthony is two more than double Brad and Chase is four less than Brad. What are the ages of all three men?
Help me please
Answer:
Anthony is 56
Brad is 27
Chase is 23
Step-by-step explanation:
Anthony's equation is 2 +2b because he is two more than double Brad
This means that Brads equation would just equal b
Chases equation would be b-4 because Chase is four less than Brad

Answer:
Look below
Step-by-step explanation:
We can start by writing an equation.
Let x be the width. The length would be x+4.
The equation would be:
96=2(x+x+4)
Divide both sides by 2
48=x+x+4
Add like terms
48=2x+4
Subtract 4 from both sides
44=2x
Divide both sides by 2
x=22
x+4=26
The width is 22 inches and the length is 26 inches.
