tan30=1/√3
tan60=√3

Now

$\\ \sf\longmapsto tan(\alpha+\beta)=\sqrt{3}$

$\\ \sf\longmapsto \alpha+\beta=60\dots(1)$

And

$\\ \sf\longmapsto tan(\alpha-\beta)=\dfrac{1}{\sqrt{3}}$

$\\ \sf\longmapsto \alpha-\beta=30\dots(2)$

Adding both

$\\ \sf\longmapsto 2\alpha=30+60=90$

$\\ \sf\longmapsto sin2\alpha=sin90$

$\\ \sf\longmapsto sin2\alpha=1$

The number of children that attend the county pool during the month of July can be represented by the function p(x)=64x+21, wher

Ad libitum [116K]

Answer:

r(x) = 135x + 59

The first choice

Step-by-step explanation:

We have the number of children represented by p(x) = 64x + 21

the number of adults represented by q(x) = 38 + 71x

for x = number of days that the pool was opened during July.

function r(x) is suppose to represent the total number of children AND adults.

so r(x) = p(x) + q(x)

r(x) = (64x +21) + (38 + 71x)

r(x) = 64x + 71x + 21 + 38

r(x) = 135x + 59

Answer:

Step-by-step explanation:

$\frac{3}{2} y - 3 + \frac{5}{3} z \\ \\ = \frac{3}{2} \times 6 - 3 + \frac{5}{3} \times 3 \\ \\ = 3 \times 3 - 3 + 5 \\ \\ = 9 - 3 + 5 \\ = 14 - 3 \\ = 11$
