To prove

As given in the question

A stack of six bricks is two feet high.

Now calculate high is a stack of 20 bricks

Svetradugi [14.3K]

Answer:

Step-by-step explanation:

6 / .5 (same as 1/2)

or 6 X $\frac{2}{1} = 12$

Remember when we divide by a fraction we do the following

Keep it (the first number stays the same)

Change it (convert from a division problem to a multiplication problem)

Flip it (flip the fraction that we are dividing by over - this is called a reciprocal)

use what you know about zeros of a function and end behavior of a graph that matches the function f(x) = (x+3)(x+2)(x-1)

Gwar [14]

Answer:

The zeros are x=-3,-2,1

end behavior is one up one down

Step-by-step explanation:

The zeros are x=-3,-2,1

The end behaviors are one up one down because the function is of degree 3 meaning it is odd function and has opposite end directions.

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;

$\overline {BC}$ to be the height of the tree and $\overline {DE}$ 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

$\dfrac{\overline {DE}}{ \overline {BC}}= \dfrac{\overline{AD}}{ \overline{AC}}$

$\dfrac{x}{ 45}= \dfrac{225-220}{225}$

$\dfrac{x}{ 45}= \dfrac{25}{225}$

By cross multiply

225x = 45 × 25

$x = \dfrac{45 \times 25}{225}$

$x = \dfrac{1125}{225}$

x = 5.0 ft

Therefore, you could stand at 5.0 ft and still be completely in the shadow of the tree
