An equation in the form ax2+bx+c=0 is solved by the quadratic formula. The solution to the equation is shown below.x=−7±√ "572"

7nadin3 [17]

Answer:

B: a = 1, b= 7, c = -2

Explanation:

$\sf Quadratic \ Equation : \dfrac{-b\pm \sqrt{b^2 - 4ac} }{2a}$

Knowing This:

solve for b

-b = -7

b = 7

solve for a:

2a = 2

a = 1

solve c:

b² - 4ac = 57

7² - 4(1)(c) = 57

-4c = 57 - 49

-4c = 8

c = 8/-4 = -2

Find the measure of angel 3

Elena-2011 [213]

Answer:

100

Step-by-step explanation:

Remark

If two opposite arcs are given by being opposite vertically opposite angles, then the value of both the vertically opposite angles are equal to

Vertically opposite angle = 1/2 (arc1 + arc2)

Givens

Arc1 = 60

Arc2 = 100

Solution

The red dot angle = 1/2 (60 + 100)

The red dot angle = 1/2(160)

The red dot angle = 80

Because the red dot angle and <3 are on the same line with the same common point, they are supplementary.

<3 and red dot = 180

<3 + 80 = 180 Subtract 80 from both sides

<3 = 180 - 80

<3 = 100

Find the area of the semicircle. diameter = 12

dimaraw [331]

Answer:

$\huge\boxed{\sf Area\ of \ Semicircle = 56.55 \ units^2}$

Step-by-step explanation:

Diameter = 12

Radius = 12/2 = 6

$\sf Area\ of \ Semicircle =\frac{\pi r^2}{2} \\Area\ of \ Semicircle =\frac{\pi (6)^2}{2} \\Area \ of \ Semicircle = \frac{\pi (36)}{2}\\ Area \ of \ Semicircle = 18 \ pi$

$\sf Area\ of \ Semicircle = 56.55 \ units^2$

-3/5x+-7/10+1/2x=-56

Savatey [412]

Answer:

$x=553$

Step-by-step explanation:

$\frac{-3}{5} x+\frac{-7}{10} +\frac{1}{2} x=-56$

Combine like terms:

$-\frac{1}{10} x =-\frac{553}{10}$

Multiply both sides by -10:

$x=553$
