Answer:3
Step-by-step explanation:
Answer:
x+%2B+28+=+2x+%2B+4
x+=+28+-+4
x+=+24
He is 24 now
Step-by-step explanation:
X^2 + 14x + 17 = -96
x^2 + 14x + 113 = 0
x^2 + 14x + 49 + 64 = 0
(x + 7)^2 = -64
x + 7 = sqrt(-64) = + or - 8i
x = -7 + or - 8i
Answer:
10/21 or 0.476 miles per hour
Step-by-step explanation:
If you divide 2/3 by 1.4 (or 14/10), you will get miles per hour.
2/3 ÷ 14/10 = 2/3 x 10/14 = 20/42 = 10/21 = 0.476
Answer:
.
Step-by-step explanation:
I graphed the region in the image below. The blue line is y=3, the purple line is x=1 and the green curve is y = 
. The shaded region in blue is the region we are going to rotate.
Now, to find the volume v= 
where a=1, b=3 (left and right points of the region), p(x) is the distance from the rotation axis to the diferential Δx, we say p(x)=x and h(x) is the height of the region, in this case is h(x)= 
. Then,
v = 
= 
= 
= 
= 
= .
