The area of a triangle is A=1/2b*h
You have the base (b) and you have the area (A)
So, if you plug in what you know, you get this:
45.5=1/2*10*h
Simplify it:
45.5=5h
Now solve for h
Divide by 5 to get h alone:
9.1=h
Your height is 9.1cm
Hope this helps :)
Answer:
B
Step-by-step explanation:
-2 is greater than -3
She has 50 stacks with 10 pennies in each, so multiply 50 by 10
50*10 = 500
so she has 500 pennies in total.
Answer:
(-∞, α)
Step-by-step explanation:
The domain is the set of all possible x-values that will make the function work.
f(x) will exist only if the radicand is positive.
Also, x cannot equal α, because f(α) = 1/√0 =1/0 = undefined. Thus, we must have
α - x > 0 or
x < α
The domain is x <α.
In interval notation, the domain is (-∞, α).
