Answer:

m = -3

Step-by-step explanation:

We can find the slope by using

m = (y2-y1)/(x2-x1)

We use two points

(0,-4) and (-2,2)

m = (2 - -4)/(-2 -0)

= (2+4)/(-2-0)

=6/-2

= -3

A student claims that -4i is the only imaginary root of a quadratic polynomial equation that has real coefficients.

slava [35]

Step-by-step explanation:

Complex roots or imaginary roots must come in conjugate pairs. If -4i is a root, that means 4i is also a root.

A possible polynomial is:

y = (x + 4i) (x − 4i)

y = x² − 16i²

y = x² + 16

An engineer needs to determine the distance across a river without swimming to the other side. The engineer notices a tree on th

nasty-shy [4]

Answer:

Step-by-step explanation:

The engineer can use a clinometer to measure the angle of elevation of the top of the tree. Let the height of the tree be represented by x, the she could determine the distance across the river, d, by applying the trigonometric function.

Tan θ = $\frac{opposite}{adjacent}$

= $\frac{x}{d}$

the the distance, d = x ÷ Tan θ

Assume the angle of elevation of the top of the tree is $30^{o}$ , and the height of the tree is 10 m, then the distance, d, across the river would be;

d = $\frac{10}{0.5774}$

= 17.3190

d = 17.32 m

The sketch to the explanation is attached to this answer for more clarification.
