Answer:

Step-by-step explanation:

g(-2)=2*(-2)^2-3*(-2)

Simplify the expression. Quantity cosecant of x to the power of two times secant of x to the power of two divided by quantity se

Art [367]

Answer:

D. 1

Step-by-step explanation:

We have the expression, $\frac{\csc^{2}x\sec^{2}x}{\sec^{2}x+\csc^{2}x}$

We get, eliminating the cosecant function,

$\frac{\sec^{2}x}{\frac{\sec^{2}x}{\csc^{2}x}+1}$

As, sinx is reciprocal of cosecx and cosx is reciprocal of secx,

i.e. $\frac{\sec^{2}x}{\frac{\sin^{2}x}{\cos^{2}x}+1}$

i.e. $\frac{1}{\cos^{2}x}\times \frac{\cos^{2}x}{\sin^{2}x+\cos^{2}x}$

Since, we know that, $\sin^{2}x+\cos^{2}x=1$

Thus,

$\frac{1}{\cos^{2}x}\times \frac{\cos^{2}x}{\sin^{2}x+\cos^{2}x}=1$

So, after simplifying, we get that the result is 1.

Hence, option D is correct.

Help? I'm pretty confuse on both of these? Please explain?

MAVERICK [17]

35 is the first answer (BAE ~ DAC)
36. We must divide 20 by 2 to get 10 because all the other sides are 2x the size. 3x-5=10 (Add 5) 3x=15 (Divide by 3) x=5 so the last answer choice is correct.

pantera1 [17]

there are 3200 children in the summer camp.

Step-by-step explanation:

Percentage of boys in summer camp= 48%

No of boys in summer camp=1536 boys

Total number of children in summer camp= $\frac{1536}{48}*100\\ =3200$

So, there are 3200 children in the summer camp.
