This is the difference of 2 squares
square root of a^6 = a^3
and square root of 25 b^2 = 5b so we get
(a^3 + 5b)(a^3 - 5b)
Thats the answer
Step-by-step explanation:
Hey there!
It looked like people were helping you with the first 2, so l'll pick up from there.
3. The graph changes direction 3 times, so it shows 3 turning points.
4. x^4 is the minimum degree polynomial model, because there are 3 turning points.
5. Look at where the graph was highest. 180 appears to be the closest number to that peak, so 180 sec is correct.
6. Look at the rise again. Where is the accelaration placed on the left side of the chart? It looks to me like 3 is closest.
I'll be waiting in the comments if you need help. :)
Answer:
D: q/r
Step-by-step explanation:
Using SohCahToa:
SOH: Sin(θ) = Opposite / Hypotenuse
CAH: Cos(θ) = Adjacent / Hypotenuse
TOA: Tan(θ) = Opposite / Adjacent
Step-by-step explanation:
The ratio of the two shorter legs of the top triangle is
![\dfrac{5}{4} = 1.25](https://tex.z-dn.net/?f=%5Cdfrac%7B5%7D%7B4%7D%20%3D%201.25)
The bottom triangle has the following ratio:
![\dfrac{7.5}{6} = 1.25](https://tex.z-dn.net/?f=%5Cdfrac%7B7.5%7D%7B6%7D%20%3D%201.25)
Since their ratios are the same, this means that the two triangles are similar.
Answer:
y = - 5x
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = - 10 when x = 2, thus
k =
=
= - 5
y = - 5x ← equation of variation
