Answer:

-74

Step-by-step explanation:

Graph the function. See attached picture. Between the interval where -4 > x < 0, the graph rises up to a peak and descends back down when x = 0. This means the minimum value will be where x = -4.

Substitute x = -4 into the equation.

f(-4) = (-4)^3 -3(-4)^2 - 9(-4) + 2

f(-4) = -64 -3(16) +36 + 2

f(-4) = -64 - 48 + 36 + 2

f(-4) = -74

Is a equilateral triangle and a right triangle similar?

neonofarm [45]

Answer:

An equilateral triangle cannot be similar to a right triangle, whereas an isosceles triangle can be similar to a right triangle.

Step-by-step explanation:

A right triangle must have a 90º angle, so it cannot be equilateral in side length and angle since the figure would no longer be a triangle.

Isosceles triangles have two same sides, so two equal angles. A right triangle can be a 45º, 45º, and 90º.

A shadow 12 meters long is cast by a fir tree that is 16 meters tall. What is the length of the shadow cast by a nearby ash tree

mrs_skeptik [129]

Answer: 5 m

Step-by-step explanation:

Given

Length of 16 m fir tree is 12 m

length of the ash tree is 8 m

Suppose x is the length of the ash tree

angle $c$ made by fir and ash tree will be same as shown in figure

$\Rightarrow \tan c=\dfrac{16}{12}=\dfrac{8}{x}\\\\\Rightarrow x=8\times \dfrac{12}{16}\\\\\Rightarrow x=5\ m$
