Given that the ladder is 10 ft long and the height of the wall is 8.5 ft, to find whether the ladder is safe resting on the window sill we use the formula:
sin x=opposite/hypotenuse
opposite=8.5 ft
hypotenuse=10 ft
thus
sin x=8.5/10
sin x=0.85
x=arcsin 0.85
x=58.21°
Since 58.21°<65° the we conclude that the ladder is very safe.

Step-by-step explanation:

plot five points of f(x)=(1/2)^x

f(0)=(1/2)^0=1

f(1)=(1/2)^1=1/2... through five gives you

y=1, 1/2, 1/4, 1/8, 1/16 for points

(0, 1),(1, 0.5),(2, 0.25),(3, 0.125),(4, 0.0625)

Which statement best describes the graph of this polynomial function f(x)=x^4+x^3-2x^2

jenyasd209 [6]

Answer:

See below description.

Step-by-step explanation:

The function $f(x) = x^4+x^3-2x^2$ has the following characteristics:

Factors: $x^2(x+2)(x-1)$
Zeros/roots: x=0, x=-2, amd x=1
Positive leading coefficient
Graph starts up, curves down through -2 on the x-axis and back up to 0 where it touches and curves down and back up again again. It comes down back through 1 and crosses.
Its graph s the shape of a W.
It has minimum values at -2.83 and -0.397
