The graph of the function f(x) = -(x+6)(x + 2) is shown below. 46 £ Mark this and return 6+ 4 2 1-2- 4 2 ++ 4 6 X Which statemen
Gala2k [10]

The correct statements regarding the behavior of a quadratic function are:

  • The function in increasing for all real values of x where -6 < x < -2.
  • The function is decreasing for all real values of x where x < -6 or x > -2.

<h3>When is a quadratic function increasing or decreasing?</h3>

A quadratic function with roots x_1 and x_2 is defined by:

y = a(x - x_1)(x - x_2)

In which a is the leading coefficient.

The coefficient influences the behavior, as follows:

  • If a < 0, the function is increasing between the roots, and decreasing otherwise.
  • If a > 0, the function is decreasing between the roots, and increasing otherwise.

In this problem, the function is:

f(x) = -(x + 6)(x + 2).

The roots are x = -6 and x = -2, and the leading coefficient is of a = -1 < 0, hence:

  • The function in increasing for all real values of x where -6 < x < -2.
  • The function is decreasing for all real values of x where x < -6 or x > -2.

HELP ASAP, WILL AWARD BRAINEST, BEING TIMED, PLEASE SHOW HOW YOU GOT ANSWER , THESE ARE ALL ESSAY QUESTIONS.
vesna_86 [32]

1) JPR, JRP, PJR, PRJ, RJP, RPJ

2) To start with there are 4 green marbles and a total of 6 marbles.

First drawing: p(green) = 4/6 = 2/3

He replaces the first marble, so for the second drawing he has again 4 green marbles out of a total of 6 marbles.

p(green) = 4/6 = 2/3

The combined probability is the product of the 2 probabilities.

p(green followed by green) = p(green) * p(green) = 2/3 * 2/3 = 4/9

3)

Total number of combinations of 3 different shirts and 2 pairs of pants is 3 * 2 - 6. You are interested in a single combination out of a possible 6.

p(white shirt & tan pants) = 1/6

Two small circles lie on the diameter of a larger circle as shown. If AB=24cm, what is the approximate area of the shaded region
brilliants [131]

We have been given a diagram where two small circles lie on the diameter of a larger circle. The diameter of the large circle is 24 cm. We are asked to find the approximate area of the shaded region.

Since smaller circles are on diameter of larger circle, so the diameter of both smaller triangles will be half of 24 cm that is \frac{24}{2}=12 cm.

We know that radius is half the diameter, so radius of large circle will be 12 cm and radii of smaller triangles will be half of 12 that is \frac{12}{2}=6 cm.

The area of shaded part will be area of larger circle minus sum of areas of smaller circles.

Area of circle formula: A=\pi r^2

\text{Shaded area}=\pi(12)^2-(\pi(6)^2+\pi(6)^2)

\text{Shaded area}=144\pi-(36\pi+36\pi)

\text{Shaded area}=144\pi-(72\pi)

\text{Shaded area}=72\pi

\text{Shaded area}=72(3.14)

\text{Shaded area}=226.08

Therefore, the area of the shaded region is 226.08 square cm and option A is the correct choice.

A towns population is 43,425. About 125 people move out of the town each month. Each month, 200 people on average move into town
jolli1 [7]

Answer 1) x = 7 so in 7 months

2) 43,425 + 75x = 45,000 - 150x

Step-by-step explanation:

basically town A is gaining 75 people monthly and town B is decreasing 150 monthly so 43,425 + 75x = 45,000 - 150x and then you find out in 7 months both town will have equal population hope i helped

∠A and ∠B are complementary angles of right triangle ABC, cos A = 0.83, and cos B = 0.55. What is sin A + sin B? A) 0.28. B) 1.
Delicious77 [7]
To answer this problem, we can find to determine angle A first by taking the arc sin of 0.83. Angle A is equal to 33.9. Hence angle B should be 90-33.9 equal to 56.10. sin of 33.9 added to the sin of 56.10 is equal to 1.38. or we can just directly add the cos values since the sin is just the same as the complementary of each
