Answer:
all are true except the -8
In this question , the triangle is equilateral triangle , with radius equals to 8 cm and we have to find the length of apotherm, a .
Using sine ratio rule,
For triangle ODC, opposite is a cm and hypotenuse is of length 8 cm .
So we will get
Multiplying both sides by 8
So the length of the apothem is 4 cm .
The lateral surface of an object is all of the sides of the object, excluding its base and top. The lateral surface area is the area of the lateral surface. This is to be distinguished from the total surface area, which is the lateral surface area together with the areas of the base and top.
Answer:
what are the options?!? you should tell us so I can help
We know the y-intercept is (0,5).
So we can say from the linear formula y = mx+b
b is 5.
we also have (-5,1) which can be subbed in the formula.
Thus, we will have an equation solving for m.
1 = m(-5)+5
-4 = m(-5)
4/5 = m
Therefore, y = 4/5x + 5
To check sub -5 into the x and see if up you get a 1. If you do it’s correct.
