The length of the rectangle is three more than the width find the length of the rectangle if the perimeter is 98 inches
Aleks [24]

Answer:

length is 26 and width is 23

Step-by-step explanation:

let width be x

then length is 3+x since it is 3 more than the width

perimeter of a rectangle = 2l + 2w

98=2 [3+x] + 2x

98=6+2x+2x

98=6+4x

98-6=4x

92=4x

x=23

width is 23 and

breadth is 26

Which expression is equivalent to RootIndex 3 StartRoot 32 x Superscript 8 Baseline y Superscript 10 Baseline EndRoot?
evablogger [386]

Answer:

The equivalent expression to the given expression is \sqrt[3]{32x^8y^{10}}=2x^2y^3\sqrt[3]{4x^2y}

Step-by-step explanation:

The given expression is \sqrt[3]{32x^8y^{10}}

To find the equivalent expression:

\sqrt[3]{32x^8y^{10}}=(32x^8y^{10})^{\frac{1}{3}}

We may write the above expression as below:

=(32^{\frac{1}{3}})((x^8)^{\frac{1}{3}})((y^{10})^{\frac{1}{3}})

=(2)((4)^{\frac{1}{3}})(x^6)\times (x^2)(x^{\frac{2}{3}})(y^3)(y^{\frac{1}{3}}) (using square root properties)

=(2\sqrt[3]{4})(x^2\sqrt[3]{x^2})(y^3\sqrt[3]{y}) (combining the like terms and doing multiplication )

=2x^2y^3\sqrt[3]{4x^2y}

Therefore \sqrt[3]{32x^8y^{10}}=2x^2y^3\sqrt[3]{4x^2y}

Therefore the equivalent expression to the given expression is \sqrt[3]{32x^8y^{10}}=2x^2y^3\sqrt[3]{4x^2y}

Your shiny new boat cost $7650. The depreciation for your boat is 14% per year. You want to know the value of your vehicle in 3
Viefleur [7K]

Answer:

The equation is

V(3) = 7650(0.86)^{3}

Which means that the value of the vehicle in 3 years is $4,865.8

Step-by-step explanation:

The equation for the value of a product with a depreciation rate of r(as a decimal) is given by:

V(t) = V(0)(1-r)^{t}

In which V(0) is the initial value.

Your shiny new boat cost $7650

This means that V(0) = 7650

The depreciation for your boat is 14% per year.

This means that r = 0.14

So

V(t) = V(0)(1-r)^{t}

V(t) = 7650(1-0.14)^{t}

V(t) = 7650(0.86)^{t}

You want to know the value of your vehicle in 3 years. What is the equation that models this problem?

The equation is

V(3) = 7650(0.86)^{3}

Which means that the value of the vehicle in 3 years is $4,865.8
