Find the percent of change. Round to the nearest tenth of a percent if necessary. 57 people to 65 people. About___ % increase.​
kap26 [50]

Answer:

  14.0% increase

Step-by-step explanation:

One formula you can use for this is ...

  percent change = ((new value)/(old value) -1) × 100%

  = (65/57 -1) × 100%

  ≈ 0.1403 × 100%

  ≈ 14.0% . . . . . . the positive sign indicates an increase

What is the area of the trapezoid?
ExtremeBDS [4]
<h2>Answer:</h2>

42 square units

<h2>Step-by-step explanation:</h2>

For a better understanding, I add an EFGH Rectangle.

The area of EFGH Rectangle = p x l

The area of EFGH Rectangle = 10 x 8

The area of EFGH Rectangle = 80cm²

The area of BHA Triangle = 1/2 x a x t

The area of BHA Triangle = 1/2 x a x t

The area of BHA Triangle = 1/2 x 6 x 4

The area of BHA Triangle = 2 x 6

The area of BHA Triangle = 12cm²

The area of AGD Triangle = 1/2 x a x t

The area of AGD Triangle = 1/2 x 4 x 2

The area of AGD Triangle = 4cm²

The area of CFD Triangle = 1/2 x a x t

The area of CFD Triangle = 1/2 x 2 x 6

The area of CFD Triangle = 6cm²

The area of BEC Triangle = 1/2 x a x t

The area of BEC Triangle = 1/2 x 8 x 4

The area of BEC Triangle = 4 x 4

The area of BEC Triangle = 16cm²

The area of the trapezoid = EFGH Rectangle - (BHA Triangle + AGD Triangle + CFD Triangle + BEC Triangle)

The area of the trapezoid = 80 - (12 + 4 + 6 + 16)

The area of the trapezoid = 80 - 38

The area of the trapezoid = 42cm²

<h3>Conclusion :</h3>

The area of the trapezoid is <u>42 square units</u>

What is f(0) when f(x)=3-2
anyanavicka [17]

Answer:

f(0)=-2

Step-by-step explanation:

We are given that f(x)=3x-2

And we are asked to determine f(0)

In order to do so, we will replace x with 0 in our function

Hence

f(0) = 3(0)-2

f(0)=0-2

f(0)=-2
