Mistake in Line 2 : Was in the determining the values for a ,b,c

Mistake in Line 4 : Not taking the square roots of both sides.

Step-by-step explanation:

${a}^{2} + {b}^{2} = {c}^{2}$

First Mistake : Line 2

$a = x \\ b = 6 \\ c = 10$

Second Mistake : Line 4

$136 = {x}^{2} \\ not \\ 136 = x$

Correct Solution :

${x}^{2} + {6}^{2} = {10}^{2} \\ {x}^{2} = {10}^{2} - {6}^{2} \\ {x}^{2} = 100 - 36 \\$

${x}^{2} = 64 \\ \sqrt{ {x}^{2} } = \sqrt{64} \\ x = 6$

Answer:

There are three transformation i.e. vertically stretch, downward and towards left.

Step-by-step explanation:

Given : Parent function and transformed function

To find : Name the type of function and describe each of the three transformations?

Solution :

Parent function get transformed into

The transformations are as follow :

1) The function is multiplied by 2 which means there is a transformation vertically by a stretch factor '2'.

2) The function is subtracted by 5 which means there is a transformation downward by a factor '5'.

3) The function inside x value get added by 3 which means there is a transformation left by a factor '3'.

Therefore, There are three transformation i.e. vertically stretch, downward and towards left.

The surface area of a cylinder is 520 ft.² The area of one of the bases is 254.34 ft.² find the height of the cylinder

morpeh [17]

Answer:

The height is 0.2003ft

Step-by-step explanation:

Given

$Surface\ Area = 520$

$Base\ Area = 254.34$

Required

The height of the cylinder

The base area of the cylinder is:

$Base\ Area = \pi r^2$

This gives

$254.34 = 3.14 * r^2$

Divide by 3.14

$81 = r^2$

Take square root of both sides

$r = \sqrt{81$

$r = 9$

The surface area of a cylinder is:

$Surface\ Area = 2\pi rh + 2\pi r^2$

This gives

$520 = 2*3.14* 9h + 2*3.14* 9^2$

$520 = 56.52h + 508.68$

Collect like terms

$56.52h = 520 -508.68$

$56.52h = 11.32$

Solve for h

$h = 11.32/56.52$

$h = 0.2003ft$
