Answer:
r = 1 ft
Step-by-step explanation:
Using the formula
d=2r
Solving for
r = d/2 = 2/2 = 1 ft
The value of p if the pair of equations may have one root common is 1.
<h3>What are the
roots of the equation?</h3>
Let the equation be ax² + bx + c = 0.
Then the roots of the equation will be

The equations are given below.
2x² + px - 1 = 0 and 3x² - 2x - 5 = 0
The roots of the equation 3x² - 2x - 5 = 0 will be
3x² - 5x + 3x - 5 = 0
(3x - 5)(x + 1) = 0
x = -1, 5/3
At x = -1, the value of p will be
2(-1)² + p(-1) - 1 = 0
2 - p - 1 = 0
p = 1
The value of p if the pair of equations may have one root common is 1.

Answer:
x = 25
y = 6
Step-by-step explanation:
< B = < M
2x - 20 = 30
2x = 50
<u>x = 25</u>
AB = LM
7y - 8 = 2y + 22
5y = 30
<u>y = 6</u>
Triangles are 180 degrees total so 80+40=120, subtract that from 180 and you’ll get B=60
