The exponential equation that represents the value of the car is [tex]A = 15000(1.08)^t[/tex].

Depreciation is the rate by which the value of an object reduces with respect to time. it is given by the formula,

[tex]A = P(1-\dfrac{r}{100})^t[/tex]

where A is the value of object after t period of time, P is the principal amount, r is the rate of depreciation, and t is the time period.

We know the formula of the depreciation, Also, the initial value of the car is $15,000, and the rate of depreciation r that is 8% per year. Therefore, the function of the depreciation of the car can be written as,

[tex]A = P(1-\dfrac{r}{100})^t\\\\A = 15000(1-\dfrac{8}{100})^t\\\\A = 15000(1.08)^t[/tex]

Hence,  the exponential equation that represents the value of the car is [tex]A = 15000(1.08)^t[/tex].

Answer:

£ 6,564.70

Step-by-step explanation:

Henry places £6000 in an account which pays 4.6% compound interest each year. Calculate the amount in his amount after 2 years

Compound Interest formula =

A = P(1 + r/n)^nt

A = Final Amounrt

P = Principal = £6,000

r = Interest rate = 4.6%

t = Time in years = 2 years

n = Compounding frequency = Yearly = 1

First, convert R percent to r a decimal

r = R/100

r = 4.6%/100

r = 0.046 per year,

Then, solve our equation for A

A = P(1 + r/n)^nt

A = 6,000.00(1 + 0.046/1)^(1×2)

A = £ 6,564.70

The amount in his account after 2 years = £ 6,564.70

Answer:

96 loaves of bread

Step-by-step explanation:

Total baking powder = 24 ounces

Baking powder used per loaf of bread = 1/4 of an ounce

loaves of bread will Jorge be able to bake = Total baking powder / Baking powder used per loaf of bread

= 24 ÷ 1/4

= 24 × 4/1

= 96 loaves of bread

loaves of bread will Jorge be able to bake = 96 loaves of bread

Answer:

1) x = 5

2) y = 5·√2

Step-by-step explanation:

1) The given parameter of the right triangle are;

The legs of the right triangle = 'x', and 5

One interior angle of the right triangle = 45°

Therefore, buy the interior angle summation property of a right triangle, we have;

The measure of the other angle, θ = 180° - 90° - 45° = 45°

From which we have;

A right triangle with an interior angle of 45° is an isosceles triangle with both legs equal

∴ The length of the other leg, x = 5

x = 5

2) By Pythagoras's theorem, we have that the square of the length of the hypotenuse, 'y', is given as follows;

y² = x² + 5²

∴ y² = 5² + 5²

y = √(5² + 5²) = √(25 + 25) = √50 = √(25 ×2) = 5·√2

y = 5·√2 in the simplest radical form.

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2(x+7)=−4x+14

(2)(x)+(2)(7)=−4x+14(Distribute)

2x+14=−4x+14

Step 2: Add 4x to both sides.

2x+14+4x=−4x+14+4x

6x+14=14

Step 3: Subtract 14 from both sides.

6x+14−14=14−14

6x=0

Step 4: Divide both sides by 6.

Answer:

Step-by-step explanation:

It takes 0.05 years account to reach $66,100

The interest rate is the amount a lender charges a borrower and is a percentage of the principal—the amount loaned. The interest rate on a loan is typically noted on an annual basis known as the annual percentage rate (APR).

According to the question, we have

Principal = 39000

Interest rate = 3.2%

The investment compounds daily.

So we can get F = [tex]39000(1+0.032)^{x}[/tex]

When F = 66100

[tex]66100=39000(1+0.032)^{x}[/tex]

⇒ [tex]\frac{66100}{39000}=(1+0.032)^{x}[/tex]

⇒ [tex]1.69=(1.032)^{x}[/tex]

⇒ [tex]x = log 1.69_{1.032}[/tex]

⇒ [tex]x = \frac{log1.69}{log1.032}[/tex]

⇒ x = 17 days

It takes 17 days account to reach $66,100

Converting days into years

= [tex]\frac{17}{365}[/tex]

= 0.045

= 0.05 (nearest tenth of a year)

Hence, It takes 0.05 years account to reach $66,100.

Answer:

y = 3x + 11

Step-by-step explanation:

obviously since y is 11 when x is zero the constant term is 11.

-4= -5c + 11

5c=15, c=3

Therefore the equation should be:
