Tan² B = 4
(tan B)² = 4
tan B = ±2

Basic Angle
= tan^-1 2
= 63.4° (1dp)

B = 63.4°, 116.6°, 243.2°, 296.6°

Assuming you're actually supposed to present your answers in 0dp, then all answers apply.

A manufacturing plant earned \$80$80dollar sign, 80 per man-hour of labor when it opened. Each year, the plant earns an addition

vagabundo [1.1K]

Answer:

$A(t)=80(1.05)^t$

Step-by-step explanation:

The manufacturing plant earned $80 per man-hour of labor when it opened

The plant earns an additional 5% for every additional man-hour t.

This can be modeled using the function:

$A(t)=P(1+r)^t$

where Initial Amount Earned, P=80

Rate of Increase, r=5%=0.05

Therefore, the function that models the amount earned at any time t is:

$A(t)=80(1+0.05)^t\\A(t)=80(1.05)^t$

Find the slope trough (-22,3) and (11,-3)

velikii [3]

Answer:

The slope is $-\frac{2}{11}$

Step-by-step explanation:

Let $(x_1,y_1)=(-22,3)$ and $(x_2,y_2)=(11,-3)$

The slope is given by;

$m=\frac{y_2-y_1}{x_2-x_1}$

We plug in the values to get;

$m=\frac{-3-3}{11--22}$

Simplify;

$m=\frac{-6}{33}$

$m=-\frac{2}{11}$
