Answer:
x=7
Step-by-step explanation:
The sum of the arc of a circle is 360 degrees
85+5x+5+10x+5+-7+6x+6+17x = 360
Combine like terms
38x+94=360
Subtract 94 from each side
38x+94-94 = 360-94
38x = 266
Divide each side by 38
38x/28 = 266/38
x = 7

The equation a[tex]x^{2}[/tex]+b[tex]x[/tex]+c=0 has roots α, β. Express (α+1)(β+1) in terms of a, b and c.
Answer:
[tex]\displaystyle \left(\alpha+1\right)\left(\beta + 1\right) = \frac{a+c-b}{a}\:\: \left(\text{ or } 1+\frac{c-b}{a}\right)[/tex]
Step-by-step explanation:
We are given the equation:
[tex]ax^2+bx+c=0[/tex]
Which has roots α and β.
And we want to express (α + 1)(β + 1) in terms of a, b, and c.
From the quadratic formula, we know that the two solutions to our equation are:
[tex]\displaystyle x_1 = \frac{-b+\sqrt{b^2-4ac}}{2a}\text{ and } x_2=\frac{-b-\sqrt{b^2-4ac}}{2a}[/tex]
Let x₁ = α and x₂ = β. Substitute:
[tex]\displaystyle \left(\frac{-b+\sqrt{b^2-4ac}}{2a} + 1\right) \left(\frac{-b-\sqrt{b^2-4ac}}{2a}+1\right)[/tex]
Combine fractions:
[tex]\displaystyle =\left(\frac{-b+2a+\sqrt{b^2-4ac}}{2a} \right) \left(\frac{-b+2a-\sqrt{b^2-4ac}}{2a}\right)[/tex]
Rewrite:
[tex]\displaystyle = \frac{\left(-b+2a+\sqrt{b^2-4ac}\right)\left(-b+2a-\sqrt{b^2-4ac}\right)}{(2a)(2a)}[/tex]
Multiply and group:
[tex]\displaystyle = \frac{((-b+2a)+\sqrt{b^2-4ac})((-b+2a)-\sqrt{b^2-4ac})}{4a^2}[/tex]
Difference of two squares:
[tex]\displaystyle = \frac{\overbrace{(-b+2a)^2 - (\sqrt{b^2-4ac})^2}^{(x+y)(x-y)=x^2-y^2}}{4a^2}[/tex]
Expand and simplify:
[tex]\displaystyle = \frac{(b^2-4ab+4a^2)-(b^2-4ac)}{4a^2}[/tex]
Distribute:
[tex]\displaystyle = \frac{(b^2-4ab+4a^2)+(-b^2+4ac)}{4a^2}[/tex]
Cancel like terms:
[tex]\displaystyle = \frac{4a^2+4ac-4ab}{4a^2}[/tex]
Factor:
[tex]\displaystyle =\frac{4a(a+c-b)}{4a(a)}[/tex]
Cancel. Hence:
[tex]\displaystyle = \frac{a+c-b}{a}\:\: \left(\text{ or } 1+\frac{c-b}{a}\right)[/tex]
Therefore:
[tex]\displaystyle \left(\alpha+1\right)\left(\beta + 1\right) = \frac{a+c-b}{a}[/tex]

The real part (red) and imaginary part (blue) of the Riemann zeta function along the critical line Re(s) = 1/2. The first non-trivial zeros can be seen at Im(s) = ±14.135, ±21.022 and ±25.011. The Riemann hypothesis, a famous conjecture, says that all non-trivial zeros of the zeta function lie along the critical line.

Three vertices of a parallelogram are (0,1), (2,0), and (2,5). Label all the possible location(s) of a fourth vertex.
Answer:
(0, 6), (4, 4), and (0, -4)
Step-by-step explanation:
basically you pick 2 sides (each with endpoints at two of the three verticies) to be the adjacent sides, and then you can easily find the fourth vertex for each case.

There are 6 wooden cubes, each of side 5 centimeters there total mass is 525 grams find the mass per cube. b)find the mass per cubic centimeter of a cube.
Answer:
(a) 87.5 g
(b) 0.7 g per cubic cm
Step-by-step explanation:
side of each cube, s = 5 cm
total mass, M = 525 g
(a) mass of each cube, m = M/6 = 525/6 = 87.5 g
(b) Volume of each cube = s x s s = 5 x 5 x 5 = 125 cubic cm
mass per cubic cm = 87.5/125 =0.7 g per cubic cm

A sinusoidal graph has a maximum at the point (–40, 3) and a midline of y = – 12. Determine the amplitude of the graph.
Answer:
15
Step-by-step explanation:
The amplitude of y=sin(x) is 1 with a maximum of y=1 and a minimum of y=-1. It's amplitude is 1 because that is the distance the max( y=1 )is from the mid line (y=0) or the distance the min( y=-1 ) is from the mid line (y=0).
So we just need to find the distance the mid line, y=-12, and the max,y= 3, is from each other.

Answer:
y+6 = 3(x-4)
Step-by-step explanation:
Point slope form is
y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y - -6= 3(x - 4)
y+6 = 3(x-4)

What do the sides in a triangle add up to? I know that the inner angles of a triangle add up to 180°, but what do the sides of a triangle add up to?
Answer:
The most basic fact about triangles is that all the angles add up to a total of 180 degrees. The angle between the sides can be anything from greater than 0 to less than 180 degrees. The angles can't be 0 or 180 degrees, because the triangles would become straight lines.
