in 1990 Jamaica's population of 2,466,000 was expected to grow exponentially by 1.1% each year. what is the range of the exponential function that decribes this growth
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.
Simplify a x b x 8 please?????
Answer:
8ab
Step-by-step explanation:
Simplify by combining like terms 9x-7y-3x-5y
Answer:
Step-by-step explanation:
6x-12y
trust me
Answer:
9x-7y-3x-5y
= 6x-12y
Step-by-step explanation:
9x and -3x are like terms as they both are "x" values
-7y and -5y are like terms as they both are "y" values
To receive the x value you subtract 3x from 9x giving you 6x
To receive the y value you subtract -5y from -7y giving you -12y
Hope that helps (:
The ratio of students to teachers at a school is 19 : 1. At this school, there are 400 people (teachers and students). How many of these 400 people are students? (enter number only, without the unit)
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
Fill the empty slots by dragging tiles from the left to show the next step for solving the equation. 14a=84
Answer:
a=6
Step-by-step explanation:
We are given that an equation
[tex]14a=84[/tex]
We have to solve the equation
To solve the equation we will use division property of equality
By using division property of equality
We get
[tex]a=\frac{84}{14}[/tex]
[tex]a=\frac{14\times 6}{14}[/tex]
[tex]a=6[/tex]
Hence, a=6
Hey guys I need help for this math problem is about function thanks if you can have a good day
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.
Math Help, due soon (homework)
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]

Solve the system below.
y = x2
y = –2x + 15
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]
Solve for each variable X and Y.

x=5 and y=7
Step-by-step explanation:
The opposite parallel sides of any rhombus are going to be equal.
a.) Knowing this you take (x+14) and make it equal to (5x-2). Then you subtract the x from (x+14), and add the 2 from (5x+2), making the new equation 16=4x. You divide 4 by x and by 16, getting the final simplified answer of x=4.
b.) Using the same method you take 3y-3 and set it equal to (2y+4). Then you subtract the 2y from (2y+4) and add the 3 from (3y-3) to bother sides. Now you have your new equation and answer being y=7.
a.) x+14 = 5x-2
b.) 3y-3 = 2y+4
factor the expression p2-16
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)

y=-3/2x-2 what is it in graph form
Answer:
Start at the point (0,-2), and go down three points, to the coordinate (0,-5), then go right 2 points, to the coordinate (2,-5). Then draw a line from (2,-5), through (0,-2)
Step-by-step explanation:
Answer:
your second point will be (2,-5) x=2 y=-5. your first point will be (0,-2) x=0 y=-2. connect them to make a line.
Step-by-step explanation:
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:
x = 9
Step-by-step explanation:
Given
(x + [tex]\frac{2}{3}[/tex] x ) - [tex]\frac{1}{3}[/tex](x + [tex]\frac{2}{3}[/tex] x ) = 10 ← distribute parenthesis
x + [tex]\frac{2}{3}[/tex] x - [tex]\frac{1}{3}[/tex] x - [tex]\frac{2}{9}[/tex] x = 10
Multiply through by 9 ( the LCM of 3 and 9 ) to clear the fractions
9x + 6x - 3x - 2x = 90
10x = 90 ( divide both sides by 10 )
x = 9

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.

1) Find AB

А
.
C
40°
103
B
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)
