Use a calculator to solve for theta in the given interval

Allushta [10]

Answer:

d. $1.82\: or\:4.46$

Step-by-step explanation:

The given trigonometric equation is;

$\sec \theta=-4.0545$

Recall that;

$\cos \theta=\frac{1}{\sec \theta}$

$\implies \cos \theta=\frac{1}{-4.0545}$

$\implies \cos \theta=-0.2466$

The cosine function is negative in the second and third quadrant.

$\theta=\pi-\cos^{-1}(0.2466)\: or\:\pi+\cos^{-1}(0.2466)$

$\theta=1.82\: or\:4.46$

The phone company NextFell has a monthly cellular plan where a customer pays a flat monthly fee and then a certain amount of mon

elena55 [62]

Answer:

Explained below.

Step-by-step explanation:

(A)

Use two-point form to determine the equation for the total monthly cost of the NextFell plan.

$(y-y_{1})=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\cdot (x -x_{1})\\\\(y-247)=\frac{247-114}{640-260}\cdot (x-640)\\\\(y-247)=0.35x-224\\\\y=0.35x+23$

(B)

Compute the total monthly cost if 949 minutes are used as follows:

$y=0.35x+23\\\\=(0.35\times 949)+23\\\\=355.15$

Thus. the total monthly cost if 949 minutes are used is $355.15.
