If on khan

the graph is pasted

A graph is a structure that resembles a set of items in mathematics, more specifically in graph theory, in which some pairings of the objects are conceptually "connected." The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.

Hope its helpful to you mark me as a brainlist

Answer:

Initial population is 2,466,000 ( p0 )

Growth is 1.1% each year ( r=1.1

p(t)=p0(1+r)t

After 30 years, the population of Jamaica should be 3.42 million by that calculation, but it is only 2.95 million, so apparently that growth rate was a little high, or wasn’t sustained.

Answer:

There are 380 students and 20 teachers.

Answer:

380

Step-by-step explanation:

Let 19x =  no. of students

        x =  no. of teachers

Then,  x + 19x = 400

20x = 400

x = 20

19x = 19(20) = 380

Answer:

since,

y = 2x and y = –2x + 15

then,

2x = –2x + 15

or, 4x = 15

or, x = 15/4

or, x = 3.75

Also,

y= 2x

= 2*3.75

= 7.5

Hope it helped

All the best!!

Answer:

Step-by-step explanation:

[tex]x^{2} = -2x^{2} +15[/tex]

add [tex]2x^{2}[/tex] to both sides

[tex]3x^{2} = 15[/tex]

divide each side by 3

[tex]x^{2} =5[/tex]

square root each side [tex]\sqrt{x^2} =\sqrt{5}[/tex]

[tex]x= 2.23606794[/tex] or rounded to the nearest hundredth [tex]x=2.24[/tex] or x = ±[tex]\sqrt{5}[/tex]

Answers:

Graph A is a function

Graph B is not a function

========================================================

Explanation:

To check if we have function or not, we apply the vertical line test. This test is where you ask yourself: "Is it possible to draw a single vertical line through more than one point on the curve?"

If the answer to that question is "yes it is possible", then we do not have a function. Graph B shows that we can draw a line through say x = 2 and have the vertical line intersect at points (2,2) and (2,4). The input x = 2 leads to multiple outputs y = 2 and y = 4 simultaneously. This is why graph B is not a function.

A function is only possible when any x input from the domain leads to exactly one y output in the range. Graph A is a function because we cannot draw a single vertical line to intersect through that curve more than once.

Answer:

The graph of g(x) is a vertical translation of f(x). Although both have the same x coordinates but different y coordinates.

The graph of g is a vertical translation of the graph of f 12 units downward.

Step-by-step explanation:

The equation y=f(x)+k represents that when k is negative, the graph moves downward.

The  complete the sentence is The graph of g is a vertical translation of the graph of f 12 units downward.

Translation is the act of moving a shape or a figure from one location to another. A figure can move in translation up, down, right, left, or anywhere else in the coordinate system. Only the object's position changes during translation; its size stays the same.

Given:

f(x) = 6x

and, g(x) = 6x – 12.

As, -12 shows the vertical translation of 12 units.

Also, The graph of g(x) is a vertical translation of f(x).

Despite having distinct y coordinates, both objects have the same x coordinates.

So, The graph of g is a vertical translation of the graph of 12 units downward.

Answer:

16.8

Step-by-step explanation:

just look at the length to the side of it (the "28") and look at the given answers. 4 seems way too small and because the line is shorter than 28 it cant be 43, so 16.8 is the most reasonable option.

Answer:

(p - 4)(p + 4)

Step-by-step explanation:

p² - 16 ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b) , then

p² - 16

= p² - 4²

= (p - 4)(p + 4)

Answer:

A

Step-by-step explanation:

Find AB using the Law of Sine:

[tex] \frac{AB}{sin(C)} = \frac{AC}{sin(B)} [/tex]

Thus:

[tex] \frac{AB}{sin(40)} = \frac{47}{sin(103)} [/tex]

Multiply both sides by sin(40)

[tex] \frac{AB}{sin(40)}*sin(40) = \frac{47}{sin(103)}*sin(40) [/tex]

[tex] AB = \frac{47*Sin(40)}{sin(103)} [/tex]

AB = 31.0056916 ≈ 31.0 cm (nearest tenth)

Step-by-step explanation:

Hey there!

First, we are given:

[tex]\frac{1\frac{1}{4}}{1\frac{3}{8}}[/tex]

To make this easier, I am going to change the fractions in to decimals.

[tex]\frac{1.25}{0.375}[/tex]

To get the unit rate, we can use proportions:

[tex]\frac{1.25}{0.375} = \frac{x}{1}[/tex]

Using cross products, we know that...

[tex]1.25 * 1 = 0.375 * x[/tex]

Now, we solve for [tex]x[/tex]:

[tex]1.25 * 1 = 0.375 * x\\ 1.25 = 0.375x\\ 3 \frac{1}{3} = x[/tex]

Therefore, the unit rate is [tex]\frac{3\frac{1}{3} }{1}[/tex]

Now, do the same with the other problem, and the unit rate is [tex]\frac{1\frac{4}{5} }{1}[/tex]

So I’m doing this right now. Basically, you need to create a chart.

x and y. So if x=0, solve for y. You need at least 2 points like this to solve it.

I’ll choose 0.

y=-3/2x-2

y=0-2

y=-2

your first point will be (0,-2) x=0 y=-2.

I’ll choose 2.

y=-3/2x-2

y=-3/2*2-2

y=-3-2

y=-5

your second point will be (2,-5) x=2 y=-5.

Answer:

She earned $20 in tips.

Step-by-step explanation:

First, you need to work out how much pay she'd get for 12 hours work:

12 x $11.25 = $135 for 12 hours work

Then, find out 2/5 of $11.25 to find out how much she would get for the 2/5 of an hour she worked:

2/5 of $11.25 = $4.50

Add both these sums together to get her total pay for hours worked:

$135 + $4.50 = $139.50

Subtract that sum from her total pay to find out how much money she earned in tips:

$159.50 - $139.50 = $20

Recipe for cookie dough= 3 2/3cups of flour

Amount of flour available for Jane = 1 3/4 cups of flour

Amount of flour Jane needs to add to make cookie dough
