Using limits, considering the end behavior of the function f(x), it is found that the correct statement is given as follows:
D. a is positive, and b is odd.
What is the end behavior of a function?It is given by it's limits as x goes to negative and positive infinity.
In this problem, we have that, considering the end behavior:
[tex]\lim_{x \rightarrow \infty} = \infty \rightarrow ax^{b + 1} = \infty[/tex][tex]\lim_{x \rightarrow -\infty} = \infty \rightarrow ax^{b + 1} = \infty[/tex]This will only be true if a is positive and b is odd, hence option D is correct.

Julia made a model of a square pyramid. She used cardboard to construct the model with the dimensions shown. It has an open bottom.
A square pyramid has a square base with side lengths of 8 centimeters, and 4 triangular sides with a height of 5 centimeters.
What is the surface area of the model?
A. 80 cm2
B. 144 cm2
C. 224 cm2
D. 320 cm2
Answers
Answer:
A. 80 cm²
Step-by-step explanation:
If a square pyramid has an open base, then the surface area is made up of the 4 congruent triangular sides only.
Area of a triangle = 1/2 × base × height
Given:
Base = 8 cmHeight = 5 cm⇒ Area of one triangular face = 1/2 × 8 × 5
= 20 cm²
⇒ Total surface area = 4 triangular faces
= 4 × 20
= 80 cm²

An 80-centimeter ramp connects the sidewalk to the bed of a truck. If the ramp
forms a 30-degree angle with the ground, the truck bed is centimeters off the ground.
Answers
The truck bed is 40cm .
What is a right-angled triangle?A right-angled triangle is a triangle with one of its angle 90°.
Analysis:
The ramp, the height of the truck bed from ground and the distance of truck bed to the point the ramp makes contact with the ground form a right angle triangle.
So that sin 30 = height of truck bed above ground/length of ramp
sin 30 = height/80
height of the truck = 0.5 x 80 = 40cm

B)

C)

D)
2x² - 4x + 3
E)
16x - 12
Answers
Answer:
f(x)= 2x² - 4x + 3
Step-by-step explanation:
dy/dx = 4x - 4
y = integrate dy/dx
y = 4x²/2 - 4x + c
y = 2x² - 4x + c
at (2,3)
3 = 2(2)² - 4(2) + c
3 = 8 -8 + c
c = 3
therefore f(x)= y = 2x² - 4x + 3
The graph of the function is given by f ( x ) = 2x² - 4x + 3
What is a function rule?The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given data ,
Let the function be represented as A
Now , the value of A is
At each point (x, y) on a graph of function f, the graph has a slope equal to 4x - 4
So , dy/dx = 4x - 4
On integrating , we get
f ( x ) = 2x² - 4x + c
where the function passes through P ( 2 , 3 )
So , 3 = 2 ( 2 )² - 4 ( 2 ) + c
c = 3
Hence , the function is f ( x ) = 2x² - 4x + 3

Let the speed of the car is c and speed of the plane is p.
We are given:The speed of the plane is 7 times the speed of the car
p = 7cThe distance traveled is
d = 315 kmThe time difference to travel this same distance is 3 hours.
We know that:d = ts, where d- distance, t- time, s - speedFind the time for car and plane and their difference.
Cart = d/s = 315/cPlanet = d/s = 315/p = 315/(7c) = 35/cThe difference315/c - 45/c = 3Solve it for c:
(315 - 45)/c = 3270/c = 3c = 270/3c = 90 km/hNow find the speed of plane:
p = 7c = 7*90 = 630 km/hAs we see, Jenny is right
