Answer:
feet/million year
Step-by-step explanation:
We are given that
Elevation of top of basalt in valley =4100 feet
Elevation of bottom of basalt in valley =2100 feet
Age of top of basalt in valley=15000 years
Age of bottom of basalt in valley=1.2 million years=
We have to find the rate of basalt filling in the valley in feet per million yeas
Rate of basalt filling in the valley=
Rate of basalt filling in the valley=
Rate of basalt filling in the valley=
feet/million year

Answer:
you could stand at 5.0 ft and still be completely in the shadow of the tree
Step-by-step explanation:
From the diagram attached below;
We consider;
to be the height of the tree and
to be the height of how tall you could be and still be completely in the shadow of the tree.
∠D = ∠B = 90°
Also;
ΔEAD = ΔBAC (similar triangles)
Therefore, their sides will also be proportional
i.e



By cross multiply
225x = 45 × 25


x = 5.0 ft
Therefore, you could stand at 5.0 ft and still be completely in the shadow of the tree
This expression is a good candidate for "factoring by grouping." I note that the first 2 terms and the last 2 terms share a common factor, 2x+1:
8x^3 + 4x^2 - 18x - 9
4x^2 *(2x + 1) -9 (2x+1)
This can be re-written as (2x+1)(4x2-9)
The latter factor is also easily factorable:
(2x+1)(2x-3)(2x+3) (answer)
