Answer,

What you are talking about is a repeating decimal. You would write the number 0.4 and over the 4 you would put a line.

Hope this helps :-)

Find (a) the value of q in radians (b) the area of the shaded region in cm²

Tresset [83]

Answer:

(a) 1.18

(b) 99.71

Step-by-step explanation:

to know the value of q in degrees we can use cosine of q

$\cos (q) = \frac{OR}{OQ}\\\\\cos (q) = \frac{5}{13}\\\\q = \cos^{-1}(\frac{5}{13})\\\\q \approx 67.38$

now to radians

the formula is

$x\times\frac{2\pi}{360}\\\\$

with x the degrees

$67.38\times \frac{2\pi}{360}\\\\=\frac{67.38\pi}{180}\\\\\approx 0.374\pi\\\\\approx 1.18$

so the measure of angle q is 1.18 radians

so now for part b

$A = \frac{r^2 \alpha }{2}\\\\$

with $\alpha$ being the central angle in radians

for degrees is the following

$A = \frac{\theta}{360}\times \pi r^2$

so we have

$A = \frac{13^2 (1.18)}{2}\\\\A = 99.71$ cm^2

A stock was purchased at $15.75 per share, and sold at $19.25 per share.

BARSIC [14]

ANSWER:
B. $3.50

STEP BY STEP EXPLANATION:

We start out with buying the stock for $15.75 then sell it at $19.25. We need to find the difference.

Subtract $15.75 from $19.25

19.25 - 15.75 = 3.50

To check your work add $3.50 to $15.75

15.75 + 3.50 = 19.25

Hope this helps and please mark brainliest! : )
