Answer:
see below
Step-by-step explanation:
Use the distributive property:
(y^2 +3y +7)(8y^2 +y +1)
= y^2(8y^2 +y +1) +3y(8y^2 +y +1) +7(8y^2 +y +1)
= 8y^4 +y^3 +y^2 + 24y^3 +3y^2 +3y + 56y^2 +7y +7
= 8y^4 +y^3(1 +24) +y^2(1 +3 +56) +y(3 +7) +7
= 8y^4 +25y^3 +60y^2 +10y +7 . . . . . matches the last choice
A. Right triangle (it has a right angle)
b. An equilateral triangle and equiangular triangle (equal sides means equal angles)
c. Right triangle (right angle)
d. Obtuse triangle (an angle greater than 90 degrees)
e. Isosceles triangle (two equal sides)
f. Scalent triangle (three different side lengths)
g. Acute triangle (angles less than 90 degrees)
h. Isosceles triangle (two equal sides because two angles are equal)
i. Equilateral and equiangular (any triangle that is equiangular is equilateral)
Answer:
answer is B
Step-by-step explanation:
as S and T are points on the same line
Answer:
The first is 0.046 and the second is 0.033
Step-by-step explanation:
Answer:
25.13274125 in³
Step-by-step explanation:
The radius = 4 ± 0.1
height = 10
Volume of a cylinder = πr²h
Actual volume of the cylinder = π × 4² × 10
= 502.6548246
Maximum volume = π × 4.1² × 10
= 528.1017251
Minimum volume = π × 3.9² × 10
= 477.8362426
Average error = (528.1017251 - 477.8362426)/2
= 50.2654825/2
= 25.13274125 in³
The units are inches cubed.
