Given:

AB = 9 in, BC = 2 in

DE = 3 in, EF = 3 in

To find:

The area of the shape

Solution:

ABCH is a rectangle.

Area of rectangle = length × width

= AB × BC

= 9 × 2

Area of ABCH = 18 in²

GDEF is a square.

Area of square = side × side

= DE × EF

= 3 × 3

Area of GDEF = 9 in²

Area of the shape = Area of ABCH + Area of GDEF

= 18 in² + 9 in²

= 27 in²

The area of the shape is 27 in².

A line of best fit predicts that when x equals 28 y will equal 27.255 but y actually equals 26 what is the residual in this case

Kobotan [32]

Answer:

The answer is -1.255 for residual value.

Step-by-step explanation:

We are tasked to solve for the residual value given that when x equals 29, y will be equals to 27.255. But, when it is tested, y actual value is 26. The formula in solving residual is shown below:

Residual value = Observed value - predicted value

Residual value = 26 - 27.255

Residual values = -1.255

if f(x)=2(x)^2+5sqrt(x+2), complete the follwoing statement ( round your answer to the nearest hundreth) : f(0)=_____

Maslowich

Answer:

$f(0)=7.07$

Step-by-step explanation:

We have the function $f(x)=2(x)^2+5\sqrt{(x+2)}$

In this case we want to find the value of f0)

To find f(0) you must replace the x in the function with the number 0 and solve as shown below

$f(0)=2(0)^2+5\sqrt{(0+2)}$

$f(0)=0+5\sqrt{(0+2)}$

$f(0)=5\sqrt{(2)}$

Therefore

$f(0)=7.07$
