1 pts The function f(x) = 12,900(0.40)x models the population of ants in a house x days after their discovery. Which statement describes the population of ants?

Answers

Answer:

f(x) = 500 • 1.1x

Step-by-step explanation:

To solve the question, we need to understand that:

- The population of ants is going to increase with time as they mate and have a population positive growth rate.

- The initial number of ants is 500.

- The rate at which it increases will be multiplied with x months

We will work our way out by removing the wrong answers first

Since,

The population cannot be decreased so we can neglect the last two options involving 0.9 as it will result in a decrease in the population.

Now we are left with two options:

a)  f(x) = 500 • 1.1x

b) f(x) = 1.1 • 500x

Since in the option (b) , 500 is multiplied with x , it is not possible as 500 is a constant initial amount and not a factor of growth of population. The growth factor is supposed to be multiple of x months.

So, the correct answer is f(x) = 500 • 1.1x

In Phoenix, Arizona, the average temperature is 85 degrees Fahrenheit or higher during 25% of the year. During about how many weeks of the year is the average temperature below 85 degrees Fahrenheit?

Answers

Answer: 39 weeks

Step-by-step explanation:

Given

The average temperature is [tex]85^{\circ}F[/tex] or higher

A year has 52 weeks

It is given 25% of the time-temperature is above [tex]85^{\circ}F[/tex]

So, in the remaining 75% of the weeks, the average temperature is less than [tex]85^{\circ}F[/tex]

No of weeks can be determined by

[tex]\Rightarrow 75\%\ \text{of}\ 52\\\\\Rightarrow \dfrac{75}{100}\times 52=39\ \text{weeks}[/tex]

The number of carbon atoms in a fossil is given by the function [tex]y = 5100(0.95)^{x}[/tex], where x represents the number of years since being discovered. What is the percent of change per year? Explain how you arrived at your answer.

Answers

Answer:

[tex]\%x=5\%[/tex]

Step-by-step explanation:

From the question we are told that:

Carbon atoms in fossil function

[tex]y=5100(0.95)^x[/tex]

 

Generally the equation a 2 year change is mathematically given by

For[tex]x=1[/tex]

[tex]y_1=5100(0.95)^1\\y_1=4845[/tex]

For [tex]x=2[/tex]

[tex]y_2=5100(0.95)^2\\y_2=4602.75[/tex]

Generally the equation percentage year changes [tex]\%x[/tex] is mathematically given by

[tex]\%x=\frac{y_1-y_2}{y_1} *100[/tex]

[tex]\%x=\frac{4845-4602.75}{4845} *100[/tex]

[tex]\%x=5\%[/tex]

Therefore  the percent of change per year is

[tex]\%x=5\%[/tex]

Tony and Edwin each built a rectangular garden. Tony’s garden is half as long and 6 times as wide as Edwin’s garden. If the area of Edwin’s garden is 400 square feet, what is the area of Tony’s garden?

Answers

Answer:

1200 ft²

Step-by-step explanation:

Let's say that Edwin's garden was 400 feet long and 1 foot wide.

If Tony's garden is half as long and 6 times as wide, then we need to divide 400 in half and multiply 1 by 6 to get the dimensions of Tony's garden.

400/2 = 200 ft

1 × 6 = 6 ft

Area of Tony's Garden = 6 x 200 = 1200 ft²

Joshua has a ladder that is 12.8 ft long. He wants to lean the ladder against a verticle wall so that the top of the ladder is 11 ft above ground. For safety reasons, he wants the angle of the ladder no greater than 75 degrees. Will the ladder be safe at this height? Show your work.

Answers

Answer: So we'll use trig to solve this because it's a right triangle. The hypotenuse is the ladder (h) and the two smaller sides are the ground and the vertical wall (w).

That angle ladder makes with the ground = €

SOH: sin € = opposite/hypotenuse

No the ladder won't be safe!!!

Now let's make it safe:

The ladder's length (w) is constant, so stays 12

So now let's ask in an inequality what height will be safe (75° or less)

what does that mean?? well as long as you put the ladder against the wall so that the height from ground to top of the ladder is < 11.6 ft!!

Answers

Answer/Step-by-step explanation:

1. B = 180 - (90 + 58) (sum of triangles)

B = 32°

Let's find a and b using trigonometric ratios:

Reference angle = 58°

Opposite = a = ?

Hypotenuse = c = 27

Adjacent = b = ?

✔️To find a, apply SOH:

Sin 58 = Opp/Hyp

Sin 58 = a/27

a = 27*Sin 58

a = 22.8972986 ≈ 22.9 (nearest tenth)

✔️To find b, apply CAH:

Cos 58 = Adj/Hyp

Cos 58 = b/27

b = 27*Cos58

b = 14.3 (nearest tenth)

2. B = 180 - (90 + 63) (sum of triangles)

B = 27°

Let's find a and b using trigonometric ratios:

Reference angle = 63°

Opposite = a = 11

Hypotenuse = c = ?

Adjacent = b = ?

✔️To find b, apply TOA:

Tan 63 = Opp/Adj

Tan 63 = 11/b

b = 11/Tan 63

b = 5.6 (nearest tenth)

✔️To find c, apply SOH:

Sin 63 = Opp/Hyp

Sin 63 = 11/c

c = 11/Sin 63

c = 12.3 (nearest tenth)

Martha has two pet poodles. Fifi, her standard poodle, weighs 7 times as much as Buttercup, her toy poodle.

Pick the diagram that models the ratio in the story.

If Fifi weighs 56 pounds, how much does Buttercup weigh?

pounds

Answers

The diagram that models the ratio in the story is diagram A.

When fifi weighs 56 pounds, Buttercup will weigh 8 pounds.

What is a ratio?

It should be noted that ratio demonstrates how many times one number can fit into another number. It contrast two numbers by ordinarily dividing them. A/B will be the formula if one is comparing one data points.

Let buttercup be x

Let Fifi be 7x

Fifi weighs 56 pounds. This will be:

7x = 56

7x = 56

Divide

x = 56 / 7

x = 8

Buttercup is 8 pounds.
