Step-by-step explanation:

Answer:

The answer is E

Step-by-step explanation:

We first are going to look at our first term on the table(the number that comes up first) which is $75.

Then we have to find the common factor. So, you divide the second number by the first number( 88.50 divided by 75 which gets us 1.18).

Now, since we found the first term and the common factor, we are going to have to find the exponent for our f(x) equation.  

We know that she bought the painting in 2009! Now the problem is asking how much the painting will cost in 2030. So, you will subtract 2030-2009 which gets you 21! So 21 is your exponent!

Equation:   F(x)= 75(1.18) ^21

The answer that you get is:    $2424.28

Let me know if you have any questions!

:)

The value of the painting in 2030 would be $2424.28.

From the given table, it can be observed that the painting increases in value over the years. Increase in value of the painting from 2009 to 2010 = ($88.50 / $75) - 1 = 18%.

The formula for determining the future value of the painting is:

FV = P (1 + r)^nm

FV = Future value

P = Present value

R = interest rate

N = number of years

The value of the painting in 2030 = $75 x (1.18)^21 = $2424.28

Answer:

x = 12

y = 60

Step-by-step explanation:

Remark

What you are given is a parallelogram. These figures have opposite sides equal and parallel. Parallelograms also have angles opposite each other equal. Put into simpler language

Equations

y = 60                 Opposite angles are equal

x + 3 = 15            Opposite sides are equal.

Solution

y = 60 (see the remark)

x + 3 = 15            Subtract 3 from both sides

x = 15 - 3

x = 12

Answer:

Part A - the independant variable is the monthly allowance, and the dependent amount is the one that he has to get As for in order to receive it.

Part B - y = 30x + 20

Step-by-step explanation:

Part A; The independent variable is monthly allowance and the dependent variables is earns in report card.

Part B; The function for this situation is;

⇒ f (x) = 30x + 20

Where, x is number of report card.

What is mean by Function?

A relation between a set of inputs having one output each is called a function.

Given that;

James earns 20 allowance every month.

And, Earn 30 for each a on his report card.

Now,

Let number of report card = x

Then, We can formulate the equation as;

⇒ f (x) = 30x + 20

Where, x is number of report card.

Hence, The independent variable is monthly allowance and the dependent variables is earns in report card.

Thus,

Part A; The independent variable is monthly allowance and the dependent variables is earns in report card.

Part B; The function for this situation is;

⇒ f (x) = 30x + 20

Where, x is number of report card.

Answer:

$12.75

Step-by-step explanation:

8.75 + 3.50 = 12.25

25 - 12.25= 12.75

Responder:

152 capacetes

Explicação passo a passo:

Dado que:

Número de capacetes = 171

Fração com defeito = 1/9

Portanto, número de capacetes com defeito:

1/9 * 171 = 19 capacetes

Número de capacetes sem defeitos:

Número total de capacetes - número de capacetes defeituosos

171 - 19 = 152 capacetes

Answer:

Cone: 100ft^3

Sphere: 200ft^2

Step-by-step explanation:

Firstly, the volume of a cone is 1/3 of the volume of the cylinder. It's literally in the formula:

[tex]V_{cone} = \frac{h \pi r^2}{3}\\\textrm{As you can notice, }\pi r^2\textrm{ is the area of the base, like in the cylinder formula}\\[/tex]

So we can just instantly tell that the volume of the cone is 100feet^3.

Not for the sphere - we can assume that if the height is the same, it's equal to two radiuses, or simply - to the diameter. Let's use the formula for the volume of a sphere, but substitute one of the radiuses with [tex]\frac{h}{2}[/tex]

[tex]V_{sphere} = \frac{4\pi r^3}{3} = \frac{2\pi r^2 h}{3} = \frac{2h\pi r^2}{3} = 2\cdot V_{cone}[/tex]

So we can instantly tell that the volume of the sphere is 200feet^3

y = -x - 9

y = 2x + 3

Find point of intersection

x = -4

Intersection: (-4,-5)

Answer:

The correct answer is;

The replacement cone holds 4·π cubic inches more than the volume of the original cone  

Step-by-step explanation:

The given measurements of the cones are;

The radius of the original cone, r₁ = 3 inches

The height of the original cone, h₁ = 4 inches

The radius of the replacement cone, r₂ = 4 inches

The height of the replacement cone, h₂ = 3 inches

The volume of a cone, V = (1/3)·π·r²·h

The volume of the original cone, V₁ = (1/3)·π·r₁²·h₁

∴ V₁ = (1/3) × π × (3 in.)² × 4 in. ≈ 37.7 in.³

The volume of the replacement cone, V₂ = (1/3)·π·r₂²·h₂

∴ V₂ = (1/3) × π × (4 in.)² × 3 in. ≈ 50.27 in.³

The ratio of the volume of the two cones is given as follows;

Volume ratio = V₁/V₂

∴ Volume ratio = (1/3) × π × (3 in.)² × 4 in. /((1/3) × π × (4 in.)² × 3 in.) = 3/4

The difference in volume, ΔV = V₂ - V₁ = (1/3) × π × ((4 in.)² × 3 in. - (3 in.)² × 4 in. = 4·π in.³

Therefore, the volume of the replacement cone is 4·π in.³ more than the volume of the original cone.

Answer:

6% growth

Step-by-step explanation:

The equation =

A = 2300(1.06)⁷

What does 0.06 represent in the equation?

The formula for Exponential growth =

y = a (1 +r)^t

Where

y = Size after time t

a = Initial size

r = Growth rate in Percentage

t = Time t

Equating both Equations together

y = a (1 +r)^t = A = 2300(1.06)⁷

1 + r = 1.06

r = 1.06 - 1

r = 0.06

Converting to percent

r = 0.06 × 100

r = 6% growth rate
