Answer: 1, it’s a continuous cuz it’s a line and not dots
2, I think the notation u use is f(x) = 50+25x
3, D: - infinity, infinity
4, R: - infinity, infinity

Given that the current salary for Ngozi is $24000 and she earns 3.5% raise yearly, the function that will represent her salary in t years will be:
A=P(1+r)^t
where:
A=future amount
P=principle
r=rate
t=time
thus plugging in the values we shall have:
s(t)=24000(1+3.5/100)^t
s(t)=24000(1.035)^t
thus the answer is:
s(t)=24000(1.035)^t
Answer:
a. Cosine is an even function
b. Sine is an odd function
c. cos(x) = sin(x + pi/2)
Step-by-step explanation:
See the plot attached.
a. In the figure it can be seen that, for example, cos(pi/2) = cos(-pi/2); therefore, cosine is even.
b. In the figure it can be seen that, for example, sin(pi/2) = 1; sin(-pi/2) = -1; therefore, sine is odd.
c. Function displacements along x-axis are made adding (or subtracting) values to x; i. e., f(x + a), where a is a constant, displace the function f(x) a steps to the left. It can be seen in the figure that sine is cosine but displaced pi/2 values to the right. So, sin(x + pi/2) will displace sine pi/2 values to the left, where cosine is placed.
Question 1: Equiangular
Question 2: Area of the parallelogram = 48 square centimeters
Question 3: Perimeter of the rectangle = 42 ft
Question 4: Area of the trapezoid = 154 square inches
Solution:
Question 1:
The given polygon is a rectangle.
The angles of each side of the polygon is 90°.
This means all angles are equal.
Hence Option A equiangular is the correct answer.
Question 2:
Area of the parallelogram = Base × Height]
= 6 cm × 8 cm
Area of the parallelogram = 48 square centimeters
Question 3:
Perimeter of the rectangle = 2(length + width)
= 2( 15 ft + 6 ft)
= 2(21 ft)
Perimeter of the rectangle = 42 ft
Question 4:
Area of the trapezoid = 


Area of the trapezoid = 154 square inches
Answer:
D. erosion
Step-by-step explanation:
The wind is a stronger erosional force in arid regions than it is in humid regions because winds are stronger. In humid areas, water and vegetation bind the soil so it is harder to pick up. In arid regions, small particles are selectively picked up and transported. As they are removed, the ground surface gets lower and rockier, causing deflation. What is left is desert pavement, a surface covered by gravel-sized particles that are not easily moved by wind.
