Answer:
The correct answer will be "0.756596 m²".
Step-by-step explanation:
The given values are:
The radius of an umbrella,
r = 0.4 m
The height of an umbrella,
h = 0.45 m
As we know,
The lateral surface of an umbrella will be:
⇒
On substituting the values, we get
⇒
⇒
So that the amount of fabric needed will be "0.756596 m²".
Answer:
x = 6/√3 = 2√3
y = 2×2√3 = 4√3
So, 1st option is correct
You would multiply negative on by -10x+5y=30 to get 10x-5y=-30
-10x-8y=30
10x-5y=-30
-13y=0
-13y/-13=0/-13
y=0
then you would plug y into -10x+5y =30
to get 10x=30
10x/10=30/10
x=3
the point would be (3,0)
Answer: (4, -3)
Step-by-step explanation:
First turn them into slope intercept form:
y=3x-15
y= -1x+1
then I used a calculator that graphs them for me
