From the graph, we can't see any clear asymptote. Also, the arrow at the right tip of the graph tells us that it continues indefinitely, i.e., both the number of years and the population increases indefinitely.
Now, notice that the population increases as the number of years increases.
Therefore, the only true statement is:
As the number of years increases without bound, the population increases without bound.

The total sales done by Paun is $50,000.
There is commission of 25% on first $2000.
There is commission of 30% on remaining that is 48,000.
The total commission will be 25% of $2,000 and 30% of 48,000.
25% of $2,000 = 25 × 2000/100
25% of $2,000 = $500
30% of 48,000 = 30 × 48,000/100
30% of 48,000 = $14,400
Total commission = $500 + $14,400 = $14,900.
Thus, the total commission earned by Paun is $14,000.

What is angle?An angle results from the intersection of two straight lines or rays at a single terminal.
Angles' Components
Vertex: The intersection of two lines or sides at an angle is called a vertex.
Arms: The angle's two sides linked at a single end.
Initial Side: A straight line from which an angle is drawn, sometimes referred to as the reference line.
∵ exterior angle = sum of opposite interior angles
∴ 7x+18 = (6x-10) + 38
7x + 18 = 6x +28

Elijah earned a score of 64 on Exam A that had a mean of 100 and a standarddeviation of 20. He is about to take Exam B that has a mean of 600 and a standarddeviation of 40. How well must Elijah score on Exam B in order to do equivalentlywell as he did on Exam A? Assume that scores on each exam are normally distributed.
Answers
Notation:
μ = mean
σ = standard deviation
Exam A:
[tex]\begin{gathered} \mu=100 \\ \sigma=20 \end{gathered}[/tex]The score of the exam is 64, so we calculate the z-score given that scores on the exam are normally distributed. The formula of the z-score is:

[tex]Z=\frac{64-100}{20}=-1.8[/tex]Exam B:
[tex]\begin{gathered} \mu=600 \\ \sigma=40 \end{gathered}[/tex]Now, we need to find a z-score equal to that of the score on Exam A. This z-score is -1.8, and the score on exam B should be:

A Native American tepee is a conical tent. Find the number of skins needed to cover a teepee 10 ft. in diameter and 12 ft. high. Each skin covers 15 sq. ft. (use = 3.14)
Answers
Since it is conical, we need to find the surface area of the top of the conical shape.
If we unfold the top part of the cone, we will have a section of a circle:
The circunference of this section is the same as the total circunference of the base of the cone, which we can get from its radius (half its diamtere):
[tex]C=2\pi r=2\pi\cdot\frac{D}{2}=2\pi\cdot\frac{10}{2}=10\pi[/tex]If we visualize the cone by the side, we see that it forms a isosceles triangle which the same height and the base euqal to the diameter:
So, we can calculate "R", the radius of the unfolded cone, using the Pythagora's Theorem:
[tex]\begin{gathered} R^2=h^2+(\frac{D}{2})^2 \\ R^2=12^2+5^2 \\ R^2=144+25 \\ R^2=169 \\ R=\sqrt[]{169} \\ R=13 \end{gathered}[/tex]The circunference of a section of a circle is the circunferece of the total circle times the fraction of the section represents of the total circle. Let's call ths fraction "f", this means that:
[tex]\begin{gathered} C_{total}=f\cdot C \\ C_{total}=2\pi R=2\pi\cdot13=26\pi \\ C=10\pi \\ f\cdot26\pi=10\pi \\ f=\frac{10\pi}{26\pi}=\frac{5}{13} \end{gathered}[/tex]The area will follow the same, the area of the section is the fraction "f" times the total area of the circle, so:
[tex]\begin{gathered} A_{total}=\pi R^2=\pi13^2=169\pi \\ A=f\cdot A_{total}=\frac{5}{13}\cdot169\pi=65\pi\approx65\cdot3.14=204.1 \end{gathered}[/tex]So, the surface area of the top of the cone is 204.1 ft². Since each skin covers 15 ft², we can calculate how many skins we need by dividing the total by the area of each skin:
[tex]\frac{204.1}{15}=13.60666\ldots[/tex]This means that we need 13.60666... skins, that is, 13 is not enough, we need one more, so we need a total of 14 skins.

The value of x in 8 / 15 = 24 / x is 45.
7 / 5 ≠ 15 / 10.
6 / 8 = 15/20
What are the solutions?In order to determine how many cups of flour is needed for 72 cookies, determine how many cups is needed for one cookies.
Amount of flour needed for one cookie = 3/48
Now, multiply this fraction by 72: 3/48 x 72 = 4.5 cups
If two fractions are proportional, when they are expressed in their simplest form, both fractions would have equal values.
46 / 69 = 2 / 3

On a sunny day, a tree and its shadow form the sides of a right triangle. If the hypotenuse is 50 meters long and the tree is 40 meters tall, how long is the shadow?
Answers
the length of the shadow is 30m
Explanation:hypotenuse = 50m
height of tree = 40 m
To solve the question, we will use an illustration:
To get the length of the shadow, we will apply pythagoras' theorem:
Hypotenuse² = opposite² + adjacent²
hypotenuse = 50m, opposite = 40m
50² = 40² + shadow²
2500 = 1600 + shadow²
2500 - 1600 = shadow²
900 = shadow²
square root both sides:
[tex]\begin{gathered} \sqrt[]{900}\text{ = }\sqrt[]{shadow^2} \\ \text{shadow = 30 m} \end{gathered}[/tex]Hence, the length of the shadow is 30m

Suppose you invest $5,000 at 4% annual interest. How much money would your investment be worth after 10 years? Round your answer to the nearest hundredth (2 places after the decimal).
Answers
The investment will be worth $7,401.22 after 10 years
Here, we want to calculate the amount the investment will be worth after 10 years
Mathematically, to get this, we will use the compound interest formula;
[tex]A\text{ = P(1 + }\frac{r}{n})^{nt}[/tex]where A is the amount after 10 years
P is the amount invested which is $5,000
r is the interest rate which is 4%, same as 4/100 = 0.04
n is the number of terms yearly the investment will be compounded. Since the interest rate is annual, then the number of times it will be compounded yearly is 1
t is the number of years which is 10 in this case
Substituting these values, we have;
[tex]\begin{gathered} A\text{ =5000 (1 + }\frac{0.04}{1})^{1\times10} \\ \\ A=5000(1+0.04)^{10} \\ \\ A=5000(1.04)^{10} \\ \\ A\text{ = 7,401.22} \end{gathered}[/tex]3 people share one sandwich equally. what fraction of the sandwich will each person get? show work and write and equation. & solution
