Answer:
sin(arccos(-4/√25)) = 0.6
Step-by-step explanation:
The expression you want to evaluate is
sin(arccos(-4/√25))
= sin(arccos(-4/5))
We place this expression into a calculator and get the result
arccos(-4/5) = 2.498 rads = 143.1°
then
sin(143.1°) = 3/5
sin(143.1°) = 0.6
sin(arccos(-4/√25)) = 0.6
Answer:
Step-by-step explanation:
step 1
Find the perimeter of one lap
we know that
The perimeter of one lap is equal to the circumference of a complete circle (two half circles is equal to one circle) plus two times the length of 96 meters
so
we have
substitute
step 2
Find the total meters of four laps
Multiply the perimeter of one lap by four

The percent of the original price, the new price is given as 86.9%
<u>Solution:</u>
Given, In August, Ralph bought a new set of golf clubs that cost $565.
The cost of the clubs was marked up to $650 in October.
We have to find which proportion can be used to find what percent of the original price the new price is, if p represents the unknown percent?
The formula is normally partial/whole equals to percentage/100. In this case $565 is partial because the price increased.
So it will be,
Whenever you get results like these, you just need to round to the nearest hundredths place, which is 86.9%.
Hence, the percentage is 86.9%
