Answer:

This equation is incorrect.

Step-by-step explanation:

The sqrt(x) does not equal x squared.

You can rewrite a square root to be to the one-half power. See if this looks correct:

x^(1/2) ?= x^2

No of course these aren't equal. Hence, this equation is incorrect.

Cheers.

Sophia had 64¢ until she spent 1 quarter. How much money does Sophia have now?

aleksklad [387]

Answer:

Sophia now has 39 cents.

Step-by-step explanation:

One quarter = 25 cents

Since Sophia had 64 cents until she spent 25 cents (1 quarter).

So we subtract 25 cents from 64 cents.

$\: \: \: 64 \: cents \\ \frac{ - 25 \: cents}{ \: \: \: 39 \: cents}$

Therefore, Sophia now has 39 cents.

Which of the following correctly expresses sin (70) + sin(30) as a product?

JulsSmile [24]

Answer:

2sin50 cos20

Step-by-step explanation:

We need to write sin (70) + sin(30) as a product. The formula used here is :

$\sin A+\sin B=2\sin (\dfrac{A+B}{2})\cos(\dfrac{a-b}{2})$

Here, A = 70 and B = 30

So,

$\sin 70+\sin 30=2\sin (\dfrac{70+30}{2})\cos(\dfrac{70-30}{2})\\\\\sin 70+\sin 30=2\sin 50\cos20$

So, the value of sin (70) + sin(30) is 2sin50 cos20. Hence, the correct option is (c).
