Answer:
Step-by-step explanation:
Circumference = 2πr
Let's set the equation equal to the formula:
16 = 2πr
16/2 = πr
8 = πr
r = 8/π
Answer:
(-3-8)/(-4+4)= -11/0= no slope and undefined
Step-by-step explanation:
Answer:
The answer to your question is:
x 1 = -0.65
x2 = 7.65
Step-by-step explanation:
Equation -x² + 7x + 5 = 0
a = -1
b = 7
c = 5
Quadratic formula x = -b ±√(b² -4ac) / 2a
x = - 7 ± √(7² -4(-1)(5) / 2(-1)
x = -7 ± √(49 + 20) / -2
x = -7 ± √69 / -2
x = - 7 ± 8.3 / -2
x1 = -7 + 8.3 / -2 x2 = -7 -8.3 / -2
x 1 = -0.65 x2 = 7.65

Hello There!
<u>Geometry</u>
The angles shown represented by the expressions (11x + 5) and (5x+59) are vertical angles
Vertical angles are congruent so we can use this equation to solve for x
<u>Basic Algebra</u>
11x + 5 = 5x + 59
step 1 subtract 5x from each side
5x - 5x cancels out
11x - 5x = 6x
now we have 6x + 5 = 59
step 2 subtract each side by 5
5 - 5 cancels out
59 - 5 = 54
now we have 54 = 6x
step 3 divide each side by 6
6x/6=x
54/6=9
we're left with x = 9
now we want to plug in 9 into x for one of the expression
11(9) + 5
11 * 9 = 99
99 + 5 = 104
so we can conclude that the measure of the angle labeled ( 11x + 5 ) is 104 degrees
Now we need to find z
<u>Geometry</u>
The angle with a measure of 104 and angle Z are supplementary angles meaning that the sum of the two is 180
So to find z we subtract the known angle (104) from 180
180 - 104 = 76
so we can conclude that z = 76
