Answer:
true
Step-by-step explanation:
I got 100 percent I took the same test today
Step 1
find the a<span>rea of the first cross section
area1=b1*h/2
b1=8 m
h=10 m
area1=6*10/2------> 30 m</span>²
step 2
find the area of the second cross section
area 2=b2*h/2
b2=12 m
h=10 m
area1=12*10/2------> 60 m²
step 3
find <span>the difference in the areas of the cross sections
</span>difference=60-30------> 30 m²
the answer is
30 m²
Answer:
Yes it is linear
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
The common difference d in an arithmetic sequence is
a₂ - a₁ = a₃ - a₂ , substitute values
4y + 1 - (y + 3) = 8y - 3 - (4y + 1) ← distribute both sides and simplify
4y + 1 - y - 3 = 8y - 3 - 4y - 1
3y - 2 = 4y - 4 ( subtract 3y from both sides )
- 2 = y - 4 ( add 4 to both sides )
2 = y → A
