Solve for x 2|x-6|+14=38

ale4655 [162]

Answer:

x=18 x=-6

Step-by-step explanation:

2|x-6|+14=38

The first step is to isolate the absolute value

Subtract 14 from each side

2|x-6|+14-14=38-14

2|x-6|=24

Divide by 2 on each side

2/2|x-6|=24/2

|x-6| = 12

Now we can seperate the absolute value into two parts, the positive and the negative

x-6 =12 x-6 = -12

Add 6 to each side

x-6+6 =12+6 x-6+6 = -12+6

x=18 x= -6

The area of a circular base of the larger cylinder is 81 pie

gayaneshka [121]

Answer:

The dimensions of the larger cylinder are 3 times the dimensions of the smaller cylinder

The surface area of the larger cylinder is 3^2. or 9 times the surface area of the smaller cylinder

If proportional dimensional changes are made to a solid figure, then the surface area will change by the square of the scale factor of similar solids

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z ----> the scale factor

x ----> the area of the base of larger cylinder

y ---> the area of the base of smaller cylinder

so

$z^{2} =\frac{x}{y}$

we have

$x=81\pi\ units^2$

$y=9\pi\ units^2$

substitute

$z^{2} =\frac{81\pi}{9\pi}$

solve for z

$z^2=9\\z=3$

Verify each statement

1) The dimensions of the larger cylinder are 3 times the dimensions of the smaller cylinder

The statement is true

Because the scale factor is equal to 3 ( see the explanation)

2) The surface area of the larger cylinder is 3^2. or 9 times the surface area of the smaller cylinder

The statement is true

Because, the surface area of the larger cylinder is equal to the surface area of the smaller cylinder multiplied by the scale factor squared

3) If proportional dimensional changes are made to a solid figure, then the surface area will change by the square of the scale factor of similar solids

The statement is true

because

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

The inverse of the function y = 9 - x 2, for all values x ≥ 3, is _____, where x can take values _____.

anastassius [24]

Inverse of y=9-x²; you just replace x by y and y by x: x=9-y².

And the value of y: y² = 9-x and y =√(9 - x) [this is the inverse function]

f⁻¹(x) = √(9-x): CONDITION : (9-x) >=0, that means x< or = 9

Answer as per your problem:

The inverse of the function y = 9 - x 2, for all values x ≥ 3, is _____y =√(9 - x), where x can take values _____x<=9.

Find the slope of the line that passes through the pair of points. (–5.5, 6.1), (–2.5, 3.1)

hjlf

Slope of the line is -1.

Step-by-step explanation:

Given points are,

(-5.5,6.1),(-2.5,3.1)

Here,

$x_{1} = -5.5 ,\ \ \ x_{2}=-2.5\\y_{1} = 6.1,\ \ \ y_{2}=3.1$

Slope = m = $\frac{y_{2}-y_{1}}{x_{2}-x{1}}$

Putting values;

$m=\frac{3.1-6.1}{-2.5-(-5.5)}\\m=\frac{-3}{-2.5+5.5}\\m=\frac{-3}{3}\\m=-1$

Slope of the line is -1.
