Answer:
y = √-1040/7
Step-by-step explanation:
The equation of a unit circle is expressed as;
x²+y² = 1
Given the coordinate of P = (-33/7, y)
Substitute the coordinate into the give expression and find y;
(-33/7)²+y² = 1
Expand
y² = 1-(-33/7)²
According to difference of two square
y² = (1+(-33/7))1-(-33/7))
y² = (1-33/7)(1+33/7)
y² = -26/7(40/7)
y² = -1040/49
y= √-1040/49
y = √-1040/√49
y = √-1040/7
Hence the value of y is y = √-1040/7
Y= 4.5 because the length is less than 6=x.
Answer:
5 2/3 hours
Step-by-step explanation:
We can use a ratio to solve this problem
hours over money
4.5 hours x hours
------------- = ------------
27 dollars 34 dollars
Using cross products
4.5 * 34 = 27 * x
153 =27x
Divide each side by 27
153/27 = 27x/27
5.666666 hours
