Answer:
Radius = 7
Step-by-step explanation:
Since BA is tangent to circle O, it creates a 90° angle with the radius
Therefore, you can use Pythagorean theorem to solve this problem
a² + b² = c²
Let's say a is the radius
b is 5
c is 8.6
a² + 5² = 8.6²
a² + 25 = 73.96
Subtract 25 from both sides
a² = 48.96
Root both sides
a ≈ 6.997142274
The total cost including taxes is $156
Answer:
x=23
Step-by-step explanation:
STEP 1. To find x-intercept/zero, substitute y=0.
0= 6x2+x-35
STEP 2. Calculate the difference.
0=-23+x
STEP 3. Move the variable to the left- hand side and change its sign.
-x=-23
STEP 4. Change the signs on both sides of the equation.
x=23
Your correct, +1 would give you one point on y line then go down and over to get your slope, so yes you are correct, good job.
