Use a half-angle identity to find the exact value of sin pi/8
Yes y=x^2 is a function because Using the definition of a function, y=x^2 is a function because for every x-value in your domain, you will only get 1 unique y-value. A quick check you can do is to use the vertical line test
Answer:
37.5 inches
Step-by-step explanation:
Applying the Pythagorean Theorem,
a²+b²=c²
where c is the diagonal length
c=√(25²+28²)= 37.5
(x-center)^2+(y-center)^2=r^2
x^2+y^2=r^2
(7)^2+(0)^2=r^2
49+0=r^2
r^2=49, r=7
x^2+y^2=49
Answer:
equation : 2x + 4 = 3x - 5
X = 9
BC = 22
