In triangle ABC , m angle A=(3x)^ , m angle B=(3x+10)^ , and m angle C=(4x-30)^ Find m m angle C

Mathematics

Answer:

B

Step-by-step explanation:

Interior angles of a triangle = 180°

3x°+3x+10°+4x-30°=180°

10x°-20°=180°

10x°=180°+20°

10x°= 200°

10x°/10=200°/10

x°=20°

How do I simplify the n^-6*n^3 topic "Negative and Zero Exponents"
Alchen [17]
Since you’re multiplying n^-6 and n^3, you can add the exponents: -6+3 = -3

n^-6 * n^3 = n^-3

If you need to finish without having a negative exponent in your answer, then remember a negative exponent means that factor is on the wrong side of the fraction.

n^-3 = n^-3 / 1 = 1/n^3

when the factor moves to the other side of the fraction, the side of the exponent changes.

(5 pts) A quadratic function f is given by f(x) = ax2 + bx + c where a is not 0. Select all
Vsevolod [243]

Answers:

  • a) True. Plug in x = 0 and it leads to y = c. Therefore, the point (0,c) is on the parabola.
  • b) False. Plug in y = 0 and apply the quadratic formula. One x intercept may sometimes be x = c, but it could easily be other values as well. Or perhaps you may not get any real number solutions at all. See part d) below.
  • c) True. If a < 0, then the leading coefficient is negative. Overall, both endpoints will tend toward negative infinity to produce a parabola that opens downward.
  • d) False. The quadratic may have one x intercept or it may not have any x intercepts at all. It depends on what the discriminant d = b^2 - 4ac is equal to. If d < 0, then we have no x intercepts. If d = 0, then we have exactly 1 x intercept. If d > 0, then we have two different x intercepts.
  • e) True. The vertex's x coordinate is -b/(2a). If b = 0, then the x coordinate of the vertex is 0. The vertical line x = 0 is directly on top of the y axis.

The revenue for a small business is modeled by the function R(x) = 5x where represents the number of items soldThe cost function
MAVERICK [17]

Answer:

P(x) = 3x - 10

Step-by-step explanation:

Given

R(x) = 5x

C(x) = 10 + 2x

Required

Determine P(x) = (R - C)(x)

In functions;

(f - g)(x) = f(x) - g(x)

So, we have:

P(x) = (R - C)(x)

P(x) = R(x) - C(x)

Substitute values for R(x) and C(x)

P(x) = 5x - (10 + 2x)

Open bracket

P(x) = 5x - 10 - 2x

Collect Like Terms

P(x) = 5x - 2x- 10

P(x) = 3x - 10
