Jim buys a skateboard for $200. The value of the skateboard depreciates by 15% each year
since buying it. Create a function to represent the value of the skateboard, f(2), in dollars,
after 3 years since buying it.

Answers

Answer: f(x)=200•(0.85)^x

Step-by-step explanation:

C(t) is the actual value of the function at time t

Co is the initial value of C at t=0

r is the decaying rate, expressed in decimal

Depreciation is often modeled as an exponential decay function. Since Jim bought a skateboard for Co=$200, its value will depreciate by r=15% = 0.15 each year since buying it.

The answer is [tex]4.5^7[/tex]

Step-by-step explanation:

This is because there are 7 copies of the same number and that means you have to put 7 at the exponential part of it. Then you have to put the original number under the exponential spot. Therefore, the answer is [tex]4.5^7[/tex].

Solve this system using the substitution method.

y = 3x - 5
x=
y=

Answers

picture has full answer

Answer:

The solution is:

x=3

y=4

Step-by-step explanation:

We need to solve this system using the substitution method.

2x + 2y = 14

y = 3x - 5

Substitution method involves placing value of x or y from one equation to other equation.

We have:

[tex]2x + 2y = 14--eq(1)\\y = 3x-5 --eq(2)[/tex]

We will put value of y from equation 2 into equation 1.

[tex]2x + 2y = 14\\Put\:y = 3x - 5\\2x+2(3x-5)=14\\2x+6x-10=14\\8x=14+10\\8x=24\\x=\frac{24}{8}\\x=3[/tex]

So, we get x =3

Now, put value of x in equation 2 to find value of y

[tex]y = 3x - 5\\Put\:x=3\\y=3(3)-5\\y=9-5\\y=4[/tex]

So, we have y = 4

The solution is:

x=3

y=4

Is the relation in the table below a function?

Answers

Answer:

No

Step-by-step explanation:

A relation is a function if every x-value has exactly one y-value.

Because the x-value 1 has two y-values (-3 and 3), the relation is not a function.

Plotting (1, -3) and (1, 3) will produce a vertical line that intersects the function at two points.

Therefore, the relation is not a function.

A bike is on sale for 45% off of the regular price. If the sale price is $299.75, what was the original price?

Answers

299.75/.45=666.11

since you’re looking for original price instead of the price on sale, you would do the opposite which is to divide.

Answer:

the original price is 545$

Step-by-step explanation:

299.75$ : 55$ = x : 100

Answers

Answer:

         x = 2

Step-by-step explanation:

(7x + 9)° is corresponding angle to (9x + 5)° angle

Therefore:

m║n      ⇒      (7x + 9)° = (9x + 5)°

(7x)° + 9° = (9x)° + 5°     {subtract (7x)° from both sides}

9° = (2x)° + 5°                    {subtract 5° from both sides}

4° = (2x)°                           {divide both sides by 2°}

 x = 2

A randomly generated password contains four characters. Each of the four characters is either a lowercase letter or a digit from 0–9. Each character in the password cannot be used more than once.

11%
28%
44%

Answers

28 is the right answer sorry if I’m wrong

The approximate probability that exactly one of the four characters will be a number is 44% option fourth is correct.

What is probability?

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

We have:

A randomly generated password contains four characters. Each of the four characters is either a lowercase letter or a digit from 0–9.

Total letters = 26

Total numbers = 10

Total = 10 + 26 = 36

Total possibilities = 36×35×34×33 = 1413720

Password with one number = C(10, 1) = 10

With three letters = C(26, 3) = = 2600

Outcomes = 2600×10 = 26000

Favorable outcomes = 26000×4! = 624000

Probability = 624000/1413720 = 0.44 = 44%

Thus, the approximate probability that exactly one of the four characters will be a number is 44% option fourth is correct.

Because of prevailing winds, a tree grew so that it was leaning 6º from the vertical. At a point d = 37 meters from the tree, the angle of elevation to the top of the trees
is a = 29° (see figure). Find the height h of the tree. (Round your answer to one decimal place.)
h =
m
d m
Additional Materials
eBook

Answers

Answer:

Height of the tree is 40.0 meters.

Step-by-step explanation:

From ΔABC,

m∠ABC = 90°

Since, m∠ABC = m∠CBD + m∠ABD

90° = 6° + m∠ABD

m∠ABD = 90°- 6° = 84°

By triangle sum theorem in ΔABD,

m∠ABD + m∠BDA + m∠DAB = 180°

84° + 29° + m∠BDA = 180°

m∠BDA = 180° - 113°

             = 67°

By sine rule in ΔABD,

[tex]\frac{\text{sin}(\angle BDA)}{d}= \frac{\text{sin}(\angle ABD)}{h}[/tex]

[tex]\frac{\text{sin}(67)}{37}= \frac{\text{sin}(84)}{h}[/tex]

h = [tex]\frac{\text{sin}(84)\times 37}{\text{sin}(67)}[/tex]

h = 39.98

h ≈ 40.0 meters

Therefore, height of the tree is 40.0 meters.

The sine rule is the ratio of the side length to the sine of the opposite angles. Then the height of the tree is 40 meters.

What is trigonometry?

Trigonometry deals with the relationship between the sides and angles of a triangle.

Because of prevailing winds, a tree grew so that it was leaning 6º from the vertical.

At a point d = 37 meters from the tree, the angle of elevation to the top of the trees is a = 29° (see figure).

∠ABC = 90

We have

In ΔABC

∠ABC = ∠CBD + ∠ABD

∠ABD = 90 - 6

∠ABD = 84

By triangle sum in ΔABD, we have

∠ABD + ∠BDA + ∠DAB = 180

                            ∠BDA = 180 - 84 - 29

                            ∠BDA = 67

Then by the sine rule, we have

[tex]\begin{aligned} \dfrac{\sin \angle BDA}{d} &= \dfrac{ \sin \angle ABD }{h}\\\\\dfrac{\sin 67}{37} &= \dfrac{\sin 84}{h}\\\\h &= \dfrac{\sin 84} \times 37{\sin 67}\\\\h &= 39.98 \approx 40 \end{aligned}[/tex]

The formula used to find perimeter of triangle is: [tex]Perimeter\: of\: triangle=Sum\:of\:length\:of\:all\:sides[/tex]

Putting values and finding perimeter:

[tex]Perimeter\: of\: triangle=Sum\:of\:length\:of\:all\:sides\\Perimeter\: of\: triangle=(7x^2 - 12)+(-5x + 30)+(3x^2 + 4x)\\Perimeter\: of\: triangle= 7x^2-12-5x+30+3x^2+4x\\Perimeter\: of\: triangle=7x^2+3x^2-5x+4x-12+30\\Perimeter\: of\: triangle=10x^2-x+18[/tex]

Here are the costs for the holiday for each person.
Travel

Hotel
£50 for each day
Spending money £350
Work out the total cost of the holiday for 4 people for 7 days.

Answers

Answer:

£3,800

Step-by-step explanation:

The computation of the total cost is shown below;

Each person cost is

Travel cost £250 (assume for 7 days)

Hotel cost £50 × 7 days = £350

Spending money £350 (assume for 7 days)

Cost for each person is £950

Since there are four persons, so the total cost would be

= £950 × 4 peoples

= £3,800

An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.

here, we have,

an = -15 + 5(n – 1)

so,
