7 0

You can use the break apart strategy which would look like:
368+231= 300+60+8 + 200+30+1
Or you could just plain and simple add 368+231

A function of the form f(x) = abx is modified so that the b value remains the same but the a value is increased by 2. How do the

olga nikolaevna [1]

Answer:

The range stays the same.

The domain stays the same.

Step-by-step explanation:

The function $f(x)=ab^{x}$ is an exponential function, where a is the coefficient, b is the base and x is the exponent.

The domain for this kind of functions is: All real numbers.

And the range is: (0,∞); this happen because the exponential functions are always positive when a>0.

Therefore, if the value of a is increased by 2, the domains will stay the same and the range will stay the same: (0,∞). The coefficient does not change the domain or the range if it keeps the same sign.

Simplify square root of (1-sin theta)(1+sin theta)

Vinil7 [7]

Recall the important identities:

i) $(a-b)(a+b)= a^{2}- b^{2}$ , the difference of squares formula.

ii) $sin^{2} x+cos^{2}x=1$ , for any angle x.

Then,

from i)

$\sqrt{(1-sin(theta))(1+sin(theta))}= \sqrt{1- sin^{2}(theta) }$

then, from ii), we have

$\sqrt{1- sin^{2}(theta) }= \sqrt{cos^{2}(theta) }=cos(theta)$

Answer: cos(theta)
