i am working on this atm.
to solve you find the horizontal (x) intercepts.
so example graph A int is +3
then you find the equation where instead of f(x) etc, 0= the equation with the X value plugged in.
IE: 0=x^3-3x^2+x-3
would fit because when you simplify 0=0
0=3^3- 3(3^2)+3-3
0=27-27+3-3
0=0+0
0=0
it matches. so A would be the equation with f(x)
and continue in the same way
Answer:
(a) 26 degrees
(b) 35 degrees
Step-by-step explanation:
(a) complementary angles add up to 90 degrees, therefore the complementary angle to 64 degrees would be 90 - 64, or 26 degrees.
(b) supplementary angles add up to 180 degrees, therefore the supplementary angle to 145 degrees would be 180 - 145, or 35 degrees.
Answer:
6 inches
Step-by-step explanation:
The formula for the area of a triangle is
b - base
h - height
the first step is to add the information that we know into the formula.
We know the area = 
and the height = 5 inches
if we had both the base and the height, the next step would be to multiply
b x h then half the answer to work out the area but as we already have the area (
) we need to work in reverse.
15 x 2 = 30
what is 5 multiplied by to get 30?
5 x ? = 30
30 ÷ 5 = 6
∴ the base = 6inches
to check if our answer is correct, we can place these numbers into the formula
A = 
A = 
(30 ÷ 2 = 15)
A = 15
I hope this was helpful :-)
Y=10x+20
y=10×5y+20
y=50y+20
-20=50y-y
-20=49y
y=-20/49
The volume of the prism is D. 280
