How to solve the side of a right triangle?

A right triangle is a triangle that has one of its angles as 90 degrees. The sum of angles in a triangle is 180 degrees.

Therefore, the side of a right triangle can be found using trigonometric ratios as follows:

Hence,

cos 15° = adjacent / hypotenuse

adjacent side = x

hypotenuse side = 33 units

cos 15° = x / 33

cross multiply

x = 33 cos 15°

x = 33 × 0.96592582628

x = 31.8755522675

Therefore,

x = 31.9 units

To investigate housing needs in the future, a town planning committee
created a model to help predict the growth of the population of the town. The
data are shown in the table.

Answers

Answer:

P(t) = 5.24(1.030)^t

Step-by-step explanation:

The model for P(t) , the population of the town, t years after 1985, best fits the data is option C. P(t) = 5.35 (1.029)^t.

What is Population Growth?

Population growth is defined as the increase in the number of people which is calculated using population growth rate.

Population growth is an exponential function.

So, the function will be of the form,

P(t) = a (b)^t

Initial population is the population in 1985.

P(0) = a (b)⁰ = 5.35

⇒ a × 1 = 5.35  (Since any number raised to 0 is 1)

⇒ a = 5.35

Population in 1990, that is after 5 years is,

P(5) = a (b)⁵ = 6.01

⇒ 5.35 (b)⁵ = 6.01

⇒ (b)⁵ = 1.123

⇒ b = 1.024

So the function which best models is P(t) = 5.35 (1.029)^t.

Hence the function is C. P(t) = 5.35 (1.029)^t.

RESULT

Use ratio and proportion.

Let x be the time it takes Dionne to fold 210 packing boxes:

[tex] \frac{175}{50} = \frac{210}{x} \\ \\ cross \: multiply \\ \\ \\ 175x = 50(210) \\ \\ x = \frac{50(210)}{175} \\ \\ x = \frac{50(210)}{175} \\ \\ x = 60[/tex]

So, it will take Dionne 60 minutes to fold 210 packing boxes.

Let y be the time it takes Elias to fold 210 packing boxes:

[tex] \frac{120}{40} = \frac{210}{x} \\ \\ cross \: multiply \\ \\ \\ 120x = 40(210) \\ \\ x = \frac{40(210)}{120} \\ \\ \\ x = 70[/tex]

So, it will take Elias 70 minutes to fold 210 packing boxes.

A cell phone plan charges $19.90 a month, plus $0.05 per text message

Create & solve an inequality that represents the number of texts, t, that can be

sent while still keeping the monthly bill under $25?

Answers

Answer:

[tex]19.9+0.05t<25[/tex]

Less than 102 text messages.

Step-by-step explanation:

Monthly charge of cell phone = $19.90

Cost of one text message = $0.05

Let number of text messages be [tex]t[/tex]

The monthly bill should be less than $25. So,

[tex]19.9+0.05t<25[/tex]

The required inequality is [tex]19.9+0.05t<25[/tex]

[tex]19.9+0.05t<25\\\Rightarrow 0.05t<25-19.9\\\Rightarrow t<\dfrac{5.1}{0.05}\\\Rightarrow t<102[/tex]

So, the number of text messages that can be sent while keeping the bill under $25 is less than 102.

For which function is the ordered pair (4, 12) not a solution?

2. y = 16 - x
3. y = x + 8
4. y = 8 - x

what’s the answer?

Answers

Answer:

4. y = 8 - x is the right answer

Answer:

4. y = 8 - x

Step-by-step explanation:

The question asks for which function is the ordered pair not a solution?

We need to substitute the ordered pair (4, 12) into x and y.

1. 12 = 3(4) (correct)

2. 12 = 16 - 4 (correct)

3. 12 = 4 + 8 (correct)

4. 12 = 8 - 4 (incorrect)

Therefore, the solution to your question is option 4.

A lab currently has 70 mg of radioactive material that decays at 3.5% per year. Federal regulation for the substance says that the material must be safely stored until it reaches its half-life, at which time the material can be disposed.

How many years will the lab have to safely

store the material before disposal?

Answers

Answer:

The lab will have to wait 19.45 yers to safely store the material before disposal.

Step-by-step explanation:

Exponential equation for substance decay:

A exponential equation for the amount of a substance after t years is given by:

[tex]A(t) = A(0)(1-r)^{t}[/tex]

In which A(0) is the initial amount and r is the decay rate, as a decimal.

Decays at 3.5% per year.

This means that [tex]r = 0.035[/tex]

So

[tex]A(t) = A(0)(1-r)^{t}[/tex]

[tex]A(t) = A(0)(0.965)^{t}[/tex]

How many years will the lab have to safely store the material before disposal?

It needs to reach half-life, that is, t for which A(t) = 0.5A(0). So

[tex]A(t) = A(0)(0.965)^{t}[/tex]

[tex]0.5A(0) = A(0)(0.965)^{t}[/tex]

[tex](0.965)^t = 0.5[/tex]

[tex]\log{(0.965)^t} = \log{0.5}[/tex]

[tex]t\log{0.965} = \log{0.5}[/tex]

[tex]t = \frac{\log{0.5}}{\log{0.965}}[/tex]

[tex]t = 19.45[/tex]

The lab will have to wait 19.45 yers to safely store the material before disposal.
