Answer:
<em>The correct answer is the first option</em>
Step-by-step explanation:
<u>Quadratic Equation</u>
The standard form of a quadratic equation is
Sometimes we need to change the expression of the same equation to the form
To accomplish that change, we usually modify the left-hand expression to make it look like the square of a binomial.
The given quadratic equation is
Recall the square of a binomial is
The first term is already present. The second term gives us the value of p:
Solving
Now we need to produce the third term . We only have 41, thus we need to add 8 to both sides of the equation:
The correct answer is the first option
A° = 1/2 (90) = 45°
b° = 1/2[360 - (110 + 90)]
b° = 1/2(160)
b° = 80°
a° + b° = 45° + 80° = 135°
Answer
135°
Answer:
r + s = -4
Step-by-step explanation:
3r + 2s = r - 8
3r + 2s - r = -8
2r + 2s = -8
r + s = -8/2
r + s = -4
Answer:
d= 10.44030651
Step-by-step explanation:
The diameter is the length between the endpoints. We can find it using the distance formula.
d= sqrt((x2-x1)^2+(y2-y1)^2 )
d = sqrt((-6-4)^2+ (-1-2)^2)
d = sqrt((-10)^2+(-3)^2)
d= sqrt(100+9)
d = sqrt(109)
d= 10.44030651
