Answer:
1.5^2 = 2.25
(it looks like 1.5 but if it's 15 then it would be 225)
Step-by-step explanation:
1.5^2 means (1.5*1.5) you multiply the number by itself by how many it says to do. So if it were 1.5^52 you would multiply 1.5 by 1.5, 52 times.
Answer: (-4, -1)

Answer:
31/40
Step-by-step explanation:
Given that:
Fraction of the trail walked intulally = 9/10
Fraction of the trail walked back = 1/8 before stopping to rest
His current distance from the beginning :
Distance walked initially - distance walked back
9/10 - 1/8
The L. C. M of 10 and 8 = 80
Hence,
9/10 - 1/8
= (72 - 10) / 80
= 62 / 80
= 31 / 40
Hence, his rest point or position is 31/40 from the beginning of the trail
Answer:
the volume of the solid is 
Step-by-step explanation:
Given the data in the question;
y = x and y = x²
so
x = x²
x - x² = 0
Radius will be; r = ( x - x² )/2
Area of the circular disk πr² = π[ ( x - x² )/2 ]²
A = 
( x - x² )²
So, our volume will be;
V = ₀∫¹ A(x) dx
we substitute
= ₀∫¹ ( x - x² )² dx
{ lets expand; ( x - x² )² = x(x-x²) -x²(x-x²) = x² - x³ - x³ + x⁴ = x² + x⁴ - 2x³ }
so we have;
= ₀∫¹ ( x² + x⁴ - 2x³ ) dx

The scneario here expressed is an aritmetic sequence because it can be explained like this:
<span><span><span>a1</span>=35
</span><span><span>an</span>=<span>a<span>n−1</span></span>+<span>17
So all the variables can fit in and will be better explained than a geometric sequence in which you need a common ratio and that is not needed in this case</span></span></span>
