Answer:
7) x = 5
8) x = 10
Step-by-step explanation:
7) 2x-3=x+2
x=5
8) 4x=2x+20
2x=20
x=10
Answer:15252.25π^3
Step-by-step explanation:
Radius=r
Circumference=247 ud
Circumference=2 x π x r
247=2πr
Divide both sides by 2π
247/2π=2πr/2π
123.5π=r
Radius=123.5π
Area of circle=π x r x r
Area of circle=π x 123.5π x 123.5π
Area of circle=15252.25π^3
Step-by-step explanation:
∑k=150(3k+2)
First find a1 and a50 :
a1=3(1)+2=5a20=3(50)+2=152
Then find the sum:
Sk=k(a1 + ak)2S50=50(5 + 152)2=3925
The domain of a function is the set of all values x can have.
From the graph, we see the least value of x is 3. x can be any value greater than or equal to 3.
The domain is
