Explain the effect of reflecting an angle.

Answers

If the angle between the mirror and the incident ray increases, the angle of incidence will decrease accordingly.
And if angle of incidence will decrease, angle of reflection will also decrease.
As we know from laws of reflection, angle of incidence is equal to angle of reflection

The population P, in millions, of a certain country can be modeled by the function P(t) = 3.98(1.02)t, where t is the number of years after 1990.

Answers

Answer:

7.35 Million

Step-by-step explanation:

So you already have the function and all you have to do is find the years.

p(t)=3.98(1.02)^t

I'm thinking that you should find the difference between 2021 and 1990. The answer would be 31 and just substitute that from t.

p(t)=3.98(1.02)^31

From here you would jut plug this function into your calculator and get a final answer of:

7.35 Million

Answers

Answer:

3)      (N)  angle Q = 90 degrees

4)      (E)  angle 1 = 88 degrees

5)      (G)  angle 3 = 110 degrees

Step-by-step explanation:

3) angle Q = 1/2(270-90) = 90

4) central angles equal arc angles

5) angle supplemental to angle 3 is 1/2(140), so angle 3 = 180-70 = 110

The original price p of an item less a discount of 60%

Answers

Answer:

p - p(.60)

Step-by-step explanation:

to find 60% of p you turn 60% into a decimal, which is .60, next you multiply .60 by p which will give you 60% off of p,

finally you take the total which is p and subtract off the discount which is .60p, thus p-p(.60)

also... another way to solve this is that if you are getting 60% off that means you are paying 40% of the price, thus you could just multiply p(.40) to get the amount the person would actually pay
