Answer:
Step-by-step explanation:
This question is asking us to find where sin(2x + 30) has a sin of 1. If you look at the unit circle, 90 degrees has a sin of 1. Mathematically, it will be solved like this (begin by taking the inverse sin of both sides):
![sin^{-1}[sin(2x+30)]=sin^{-1}(1)](https://tex.z-dn.net/?f=sin%5E%7B-1%7D%5Bsin%282x%2B30%29%5D%3Dsin%5E%7B-1%7D%281%29)
On the left, the inverse sin "undoes" or cancels the sin, leaving us with
2x + 30 = sin⁻¹(1)
The right side is asking us what angle has a sin of 1, which is 90. Sub that into the right side:
2x + 30 = 90 and
2x = 60 so
x = 30

Answer:
p+q = 38/15
Step-by-step explanation:
2/3+p = 1. p = 1 - 2/3
4/5 + q = 3. q = 3 - 4/5
p + q = 1 - 2/3 + 3 - 4/5
-2/3 - 4/5 (common denominator = 15)
4 - 10/15 - 12/15 = 4 - 22/15
4 - 22/15 = (4*15 - 22)/15
= 38/15
Answer..
Step-by-step explanation:
the percent increase in the price of a gallon of milk from 1985 to 2005 is 59%
Define percent increase
Percent increase can be described as the rise in the value of an item, in this case the value is milk.
Write out the parameters
In 1985 the price of a gallon of milk is $2.20
In 2005 the price is $3.50
Formula for percent increase
new price-old price/new price × 100
Calculate the percent increase
new price= $3.50
old price= $2.20
= 3.50-2.20/2.20
= 1.3/2.20
= 0.59 × 100
= 59%
Hence the percent increase from 1985 t0 2005 is 59%
