Answer 1

Answer:

Given

Step-by-step explanation:

The Lateral surface area is the surface area of only 4 sides of the figure, that is, area excluding top and bottoms sides.

Lateral surface area of cuboid

= 2h (l+b)

where h is height

b is breadth

l is length

= 2*12 (5+4)

= 2*12*9

= 216 m^2

Lateral surface area of cube

= 4s^2

where s is the side

= 4*(2)^2

= 4*4

= 16m^2

4^2 + 5 • 3^2 – 4^2 ÷ 2^3

Answers

Following the order of operations:
4^2 + 5 * 3^2 – 4^2 / 2^3
16 + 5 * 3^2 – 4^2 / 2^3
16 + 5 * 9 – 4^2 / 2^3
16 + 5 * 9 – 16 / 2^3
16 + 5 * 9 – 16 / 8

What is the equation, in slope-intercept form, of the line that contains the points (3, -4) and (5 -6)

Answers

Answer:

y = -x - 7

Step-by-step explanation:

As we move from the point (3, -4) to the point (5, -6), x increases by 2 and y decreases by 2. Thus, the slope of this line is m = rise / run = -2/2, or -1.

Starting with the general slope-intercept form of the equation of a straight line, we get y = mx + b => y = -1x + b.

Subbing -4 for y and 3 for x, we get

-4 = -1(3) + b, which yields b = -1

Thus, the desired equation is

y = -x - 1

Describe the translation on the graph of f(x)=x to get the graph of g(x) = 3/4(x-7) - 9

Answers

First there was a vertical shrink by a factor of 3/4, then there was a translation on the x axis 7 east or right. Lastly there was a vertical shift down or south 9 units.

fist x change3/4 times ,get g(x) =3/4x,then fx move 7 on the right ,get g(x) =3/4(x-7),then f(x)move down 9,get g(x) = 3/4(x-7) - 9
