Step-by-step explanation:
The formula for the surface area of a prism is obtained by taking the sum of (twice the base area) and (the lateral surface area of the prism). The surface area of a prism is given as S = (2 × Base Area) + (Base perimeter × height) where "S" is the surface area of the prism.
Sides given by
Opposite sides must be equal
Let's check once
Find sides now
- 10in
- 2+2=4in
- 2+5=7in
- 2(2)+3=4+3=7in
One pair of opposite sides are equal but others not .
Answer:
Given that,
In right triangle ABC, C is the right angle.
sin A=0.4
To find cos B,
we get the triangle as,
we know that,
Hypotenuse of the triangle is AB
For the angle A, opposite side is CB
For the angle B, adjacent side is CB
From the definition of sine and cosine we get,
Also,
Comparing both we get,
It is given that sinA=0.4
Hence we get, cosB=0.4
Answer is: 0.4
Answers:
- slope = 1
- equation is y = x-4
============================================
Explanation:
Two points on this diagonal line are (0,-4) and (1,-3)
Let's apply the slope formula to get the following
m = (y2-y1)/(x2-x1)
m = (-3-(-4))/(1-0)
m = (-3+4)/(1-0)
m = 1/1
m = 1
The slope is 1. We can think of it as 1/1 to indicate "go up 1, and over to the right 1". In other words, slope = rise/run = 1/1.
----------
Note how the graph crosses the y axis at -4, so this is the y intercept.
Since the y intercept is -4, this means b = -4
So with m = 1 and b = -4, we go from y = mx+b to y = 1x+(-4) which simplifies to y = x-4
