The sine of the complimentary angle to 75° a. 0.65 c. 0.34 b. 0.57 d. 0.26
2 answers:
Answer:
d. 0.26
Step-by-step explanation:
We are asked to find the value of the The sine of the complimentary angle to 75°.
Since we know that complementary angles add up-to 90 degrees, so let us find the measure of complementary angle of 75° angle by subtracting 75° from 90°.
Now let us find the sine of 15 degree angle. Using a calculator we will get,
Upon rounding our answer to nearest hundredth we will get,
Therefore, the sine of complementary angle to 75° is 0.26 and option 'd' is the correct choice.

The equation for the amount of salary after x number of years is given by:
where
a is the initial amount
x represents the number of years and
r represents the growth rate( in decimal)
As per the statement:
You begin your first day as a police officer earning $30,000/yr
⇒ a= 30,000
It is also given that you obtain a full 5% increase each year,
⇒
then;
....[1]
we have to find the salary in three years.
⇒
Substitute this value in [1] we have
Simplify:
therefore, your salary be in three years will be $34,4728.75
Answer:
(3,6)
Step-by-step explanation:
Given that Mila reads at a rate of 2 paragraphs per minute. After reading for 3 minutes, she had read a total of 6 paragraphs.
This situation can be represented with a linear equation written in slope-intercept form, as
where 'x' represents the number of minutes and,
y represents the number of paragraphs.
Since y intercept is 0 i.e. 0 paras in 0 minutes we have the equation as
Since no of minutes or paragraphs cannot take negative values this line is defined only in the I quadrant where both x and y are positive
Out of the points given as follows:
(3,6) (2,3) (-3,6) or (-2,6) ,
we can remove last two since they have negative x which is impossible.
Consider (3,6) (2,3)
Out of these only I point (3,6) satisfies and second point (2,3) does not satisfy
Hence answer is (3,6)
