Answer:

347.04 m²

Step-by-step explanation:

Total surface area = central rectangular prism + (1/2 left + 1/2 right)cylinder

a = 2x(11x3+11x6+6x3) + (2xπx(6/2)²+2xπx(6/2)x3)

= 234 + 113.04

= 347.04

The slope of y = 3x - 4 on the interval [2, 5] is 3 and the slope of y = 2x^2-4x - 2 on the interval [2, 5] is 10

<h3>How to determine the slope?</h3>

The interval is given as:

x = 2 to x = 5

The slope is calculated as:

$m = \frac{y_2 -y_1}{x_2-x_1}$

16. y = 3x - 4

Substitute 2 and 5 for x

y = 3*2 - 4 = 2

y = 3*5 - 4 = 11

So, we have:

$m = \frac{11 - 2}{5 - 2}$

$m = \frac{9}{3}$

Divide

m = 3

Hence, the slope of y = 3x - 4 on the interval [2, 5] is 3

17. y = 2x^2-4x - 2

Substitute 2 and 5 for x

y = 2 * 2^2 - 4 * 2 - 2 = -2

y = 2 * 5^2 - 4 * 5 - 2 = 28

So, we have:

$m = \frac{28 + 2}{5 - 2}$

$m = \frac{30}{3}$

Divide

m = 10

Hence, the slope of y = 2x^2-4x - 2 on the interval [2, 5] is 10

A line passes through the point (0, 2) and has a slope of -1/4 What is the equation of the line?

maw [93]

Answer:

The required equation is x + 4y = 8 !!

Step-by-step explanation:

Given :-  the line passes through the point ( 0 , 2 ) and the slope of the line is ( -1/4 )

• Also, to form an equation when a point through which line passes and slope of line is given we use the formula ;

( y - y1 ) = m ( x - x1 )

Where , y and x are variables

and ( x1 , y1 ) are the points through which line passes

also, m = slope of the required line

Here , x1 = 0 , y1 = 2 and m = ( -1/4 )

Can someone help plz

Misha Larkins [42]

Answer: 5/4x

Step-by-step explanation:

To solve this you'll need to use the slope formula which is

Y2 - Y1 over

X1 - X2

You already have two points so that's what we'll use.

(4, 7) (12, 17)

17 - 7

12 - 4 = 10/8

10/8 can be simplified further to 5/4
