If f(x) has a y-intercept at 5 and x-intercepts at 2 and −4, and if g(x) = −2f(x), what are the intercepts of g(x)?

Answers

Answer 1

Answer:

y-intercept: -10x-intercepts: 2 and -4

Step-by-step explanation:

You want to know the intercepts of g(x) = -2f(x), where the intercepts of f(x) are (0, 5), (2, 0) and (-4, 0).

Vertical scaling

The scale factor of -2 applied to f(x) multiplies each of the y-coordinates by -2.

  (x, y) ⇒ (x, -2y)

  (0, 5) ⇒ (0, -10) . . . . y-intercept

  (2, 0) ⇒ (2, 0) . . . . . x-intercept

  (-4, 0) ⇒ (-4, 0) . . . . x-intercept

The intercepts of g(x) are (0, -10), (2, 0) and (-4, 0).

Answer 2

The intercepts of g(x) = -2f(x) are (0, -10), (2, 0), and (-4, 0).

What are coordinates in a graph?

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

f(x) has a y-intercept at 5 and x-intercepts at 2 and −4.

This means,

(0, 5), (2, 0), and (-4, 0)

Now,

g(x) = -2f(x).

This means,

Vertical scaling.

Multiply -2 with the y-coordinate.

(0, 5) = (0, -10)

(2, 0) = (2, 0)

(-4, 0) = (-4, 0)

Now,

The intercepts are (0, -10), (2, 0), and (-4, 0).

Answers

Answer:

11.66cm (c)

Step-by-step explanation:

Apply the phuthagorean theorem

Side opposite to the right angle in triangle is AC

AC²=ab²+bc²=10²+6²=100+36=136

We need AC so take the square root of 136 which is 11.66 as the answer

Answer:

y = 3 sin 4x

Step-by-step explanation:

For y = a sin bx,

a is the amplitude which is the crest of the graph. In this case a = 3 from the given graph.

Now, b is associated with the period where; b = 2π/period

From the graph the period which is the time between where the graph crosses the x-axis = π/2

Thus; b = 2π/(π/2)

b = 4

Thus,equation is; y = 3 sin 4x

The designer wants to plant new flowers around the pond. How many feet of flowers would she need to plant in this new design? Round to the nearest hundredth. Show your work.

Answers

Answer: 1,257.14 ft

Step-by-step explanation:

The question is missing the vital detail of the diameter or radius of this circular pond which I found to be 400 feet.

The plants are to be planted around the pond which means that they are to be planted around the circumference of the pond.

The number of feet of flowers to be planted is therefore the circumference.

Circumference = π * diameter

= 22/7 * 400

= 1,257.14 ft

Answer:

(D) or 703.4^2 is the answer here.

Step-by-step explanation:

Well I would imagine this.

Imagine a cylinder right and its liek a soda can. If you cut the middle straight down (which is the height) and you pull out the whole sheet and flatten it, you get a rectangle. You have the height but no width. The width can be found be finding the Circumfrnce of the circle or the perimeter of the circle on top.

Circumfrence formula is C=dπ or in this case the radius is 7, double the radius which would be 14 and the diameter, multiply that by π, you’d Get 43.98229 smth.

Now you have the surface for that rectangle or the surface recall for the whole cylinder except for the top and bottom, you just gotta find the top and double it!.

The area of a circle is a=πr^2

Raidus in. This case is 7, 7^2=49. 49π double it (top and bottom) is 307 smth Yu add those two up and you’d get 703.4 smth so the answer is (D).

Out of the 125 children at summer camp, 45 signed up for swimming and 38 signed up for arts and crafts. Twelve students who signed up for swimming also signed up for arts and crafts. If a child is randomly selected, what is the probability that they are signed up for swimming, if it is known that they did not sign up for arts and crafts? Please help!​

Answers

Answer:33/125

Step-by-step explanation:

First, you subtract 12 from 45, because there were 45 who signed up for swimming and 12 of them also signed up for arts and crafts. So, there are 33 children, out of the 125, who only signed up for swimming. Which means there is a 33/125 chance that a child who only signed up for swimming is randomly selected.
