Answer: the second option
explanation: below
Answer:
need pictures of the graphs
Step-by-step explanation:
basically, you'll be looking for a graph that has shifted to the RIGHT 4 units and down 2 units
The numbers are "x" and "y"
Therefore, we can suggest this system of equations:
x+y=10 ⇒x=10-y
xy=-60
Solve this system of equations by substitution method.
(10-y)y=-60
10y-y²=-60
y²-10y-60=0
Solve this square equation:
y=[10⁺₋√(100+240)]/2=(10⁺₋2√85)/2=5⁺₋√85
We have two solutions:
y₁=5-√85 ⇒x₁=10-(5-√85)=5+√85
y₂=5+√85 ⇒x₂=10-(5+√85)=5-√85
Answer: the numbers are (5-√85) and (5+√85)
Answer:
I Believe the answer is 38.48
Step-by-step explanation:
How I got this answer by using the formula (A = π × r2)
so you would plug in π x 3.5^2 (because it's your radius) and square to get the answer of 38.48451001, if you round it would be 38.48
