If f(x) = 5x – 2 and g(x) = x+1, find (f = g)(x).
OA. 5x - x-3
B. 5x2 +1
O C. 5x® - X-1
D. 5x4 - 2
Answer: Choice A) 5x^3 - x - 3
=================================================
Work Shown:
We subtract the two functions like so
(f - g)(x) = f(x) - g(x)
(f - g)(x) = ( 5x^3-2 ) - ( x+1 )
(f - g)(x) = 5x^3 - 2 - x - 1
(f - g)(x) = 5x^3 - x - 3 ..... choice A
Note: be sure to remember to distribute the negative to every term inside (x+1), and not just to the x only.
2. The measure of an interior angle of a regular polygon is 160 degrees. Find the number of sides in the
polygon
Answer:
18 sides
Step-by-step explanation:
(N x 180) - 360 = 160N
180N -360 = 160N
20N = 360
N = 18
Proof:
(18 x 180) -360 = 2880 total degrees
2880/18 sides = 160°

Express the following equation in the form ax^2+bx+c=0:
(4a+3)^2=(a+5)(a−2)
Answer:
15a² + 21a + 19 = 0
Step-by-step explanation:
Given
(4a + 3)² = (a + 5)(a - 2)
(4a + 3)(4a + 3) = (a + 5)(a - 2 ) ← expand both sides using FOIL
16a² + 24a + 9 = a² + 3a - 10 ( subtract a² + 3a - 10 from both sides )
16a² - a² + 24a - 3a + 9 + 10 = 0 ← collect like terms
15a² + 21a + 19 = 0
One leg of an isosceles right triangle measures 5 inches. Rounded to the nearest tenth, what is the approximate length of the hypotenuse?
A: 2.5 inches
B: 5.0 inches
C: 7.1 inches
D: 9.8 inches
In ΔPQR, the measure of ∠R=90°, the measure of ∠P=38°, and PQ = 62 feet. Find the length of RP to the nearest tenth of a foot.
Answer:
48.9 feet
Step-by-step explanation:
cos P = Adj / Hyp = X / 62
cos 38 = X / 62
X = 48.8567 = 48.9

Step-by-step explanation:
Hello There!
A is not true because overall 22% had trucks of the 100 people while only 9% overall had a van. So more people overall had trucks then vans meaning that vans has the lowest percentage of type of vehicle driven therefore we can eliminate answer choice A
B is also incorrect because from ages 41-50, a total of 14 people drive a van or sedan. Also from ages 41-50, a total of 14 people drive a SUV or truck. Because the total of people that drive each of the grouped vehicles is the same neither of the percentages would be lower or higher therefore we eliminate answer choice B
C is also incorrect because the same amount of people in the age group 31-40 drive trucks as the amount of people in the age group 41-50. Because the same amount of people from the different age groups drive trucks the percentage would be neither higher nor lower therefore C is incorrect
D is the correct answer choice because the total amount of people that drive trucks from the age range 21-30 is the same as the amount of people that drive a truck from other age groups. Or to be more specific the sum of the people who drive a truck from ages 31-40, 41-50 and over 50 is 11 (3+4+4=11) This meaning that the same percentage of people in the age range from 21-30 that drive a truck is the same as the percentage of people that drive a truck from the sum of the other age ranges. Hence the correct answer choice is D

Answer:
SA = 384 in²
Step-by-step explanation:
Assuming we're finding surface area:
SA of top of large cube: 8(8) - 4(4) = 48 in²
SA of sides of large cube: 4(8)(8) = 256 in²
SA of exposed faces of small cube: 5(4)(4) = 80 in²
Total = 48 + 256 + 80 = 384 = ∑SA

Answer:
(d) SA = 36π
Step-by-step explanation:
The surface area of a cylinder is ...
SA = 2πr(r +h)
Here, the radius is r=2 and the height is 7, so we have ...
SA = 2π(2)(2+7) = 36π . . . . matches choice D

Dimensions are in meters, so area is in square meters.
