Answer:
FV= 5,958.67 = 5,959
Step-by-step explanation:
Giving the following information:
Current population (Present Value)= 3,810
Growth rate (g)= 3.5% annual
Number of periods (n)= 13 years
To calculate the future number of people (FV), we need to use the following formula:
FV= PV*(1+i)^n
FV= 3,810*(1.035^13)
FV= 5,958.67 = 5,959

35*36=1260
Step-by-step explanation:
Answer:
35, 36
Step-by-step explanation:
Let the two consecutive positive integers be x and (x + 1)
According to the given information:
[tex]x(x + 1) = 1260 \\ \\ {x}^{2} + x - 1260 = 0 \\ \\ {x}^{2} + 36x - 35x - 1260 = 0 \\ \\ x(x + 36) - 35(x + 36) = 0 \\ \\ (x + 36)(x - 35) = 0 \\ \\ x + 36 = 0, \: \: x - 35 = 0 \\ \\ x = - 36, \: \: x = 35 \\ \\ \because \: x \in \: positive \: integer \\ \\ \therefore \: x \neq \: - 36 \\ \\ \therefore \: x = 35 \\ \\ x + 1 = 36[/tex]
Which correlation coefficient represents the strongest downward trend in a data set? -0.83 -0.23 0.12 0.92
Answer: -0.83
Step-by-step explanation:
A correlation coefficient(r) is used to determine the strength and direction of the relationship between two variables.
-1 ≤ r ≤1
For downward trend r is negative.
For strong correlation r should be closer to 1 or -1.
From the given correlation coefficients -0.83 is both negative and closer to -1.
Hence, a correlation coefficient represents the strongest downward trend in a data set = -0.83
Find the value of x in the triangle shown below
Answer:
Step-by-step explanation:
Pythagorean theorem,
Base² + altitude² = hypotenuse²
x² + 3² = 6²
x² + 9 = 36
x² = 36 - 9
x² = 27
x = √27
Answer:
D) x=sq rt 27
Step-by-step explanation:
using the Pythagorean theorem
6^2=3^2+x^2
36=9+x^2
27=x^2
x=sq rt 27
Phil is making a number cube out of cardboard He traces one face of the number cube onto a coordinate grid The coordinates of two opposite vertices of the face are (4, 8) and (12, 16) What is the surface area, in square units, of Phil's entire number cube?
=============================================================
Explanation:
Let A = (4,8) and B = (12,16)
Form point C at the location (12,8). Note how points A and C are on the same horizontal level, or they have the same y coordinate.
The distance from A(4,8) to C(12,8) is 12-4 = 8 units. Ignore the y coordinates and subtract the x coordinates. This trick only works for horizontal line segments.
So we can see that each square face has a side length of 8 units. The area of each square face is 8^2 = 8*8 = 64 square units.
There are six of these faces, so 6*64 = 384 square units is the total surface area of the number cube.

Answer:
[tex]y = 2(2) {}^{x} [/tex]
Step-by-step explanation:
It ask us to create a exponential function. A exponential function is represented by a equation like this
[tex]y = ab {}^{x} [/tex]
where a is the vertical stretch, b is the constant rate of growth, and x is the nth exponet.
Using the point 0,2
we can plug that in to find a part of the equation above.
let x=0 and y=2
[tex]2 = ab {}^{0} [/tex]
[tex]b {}^{0} = 1[/tex]
[tex]2 = a \times 1[/tex]
[tex]a = 2[/tex]
Let update the equation now since a equal 2
[tex]y = 2b {}^{x} [/tex]
Now let use point 2,8 to find the b value
let x=2 and y=8
[tex]8 = 2b {}^{2} [/tex]
Divide both sides by 2
[tex]4 = {b}^{2} [/tex]
take the sqr root of 4
[tex]b = 2[/tex]
Let update the equation
[tex]y = 2(2) {}^{x} [/tex]
Find the value of x.
Answer:
x = 4
Step-by-step explanation:
ΔABC ≈ ΔDBE
set up a proportion of corresponding sides:
BD / BE = BA / BC
BA = 10 - x + x = 10
10-x / 3 = 10 / 5
cross-multiply:
5(10 - x) = 3(10)
50 - 5x = 30
-5x = -20
x = 4

Answer:
8/5
Step-by-step explanation:
this is a slope formula which formats y=mx+b
m being the slope
and b being the y-intercept
so no need to look far, and no need to solve anything but 8/5 would be your y-intercept
:)) have a great day!
What is the slope of the line?
Answer:
1
Step-by-step explanation:
[tex]\frac{rise}{run}=slope[/tex]
[tex]\frac{1}{1} =1[/tex]
therefore the slope is 1
plz mark me brainliest. :)
Answer:
y = x + 5
1 would be the slope AKA m
Step-by-step explanation:
y = mx + b
mx is change of y to the change in x.
m is the slope
As you can see in the problem above, everytime y moves up 1, x moves to the right 1.
b is the y intercept - where is y when x is at 0?
This will help you find the slope of future problems hopefully. :)

Answer:
x=3
Step-by-step explanation:
The problem can be re-written as :
[tex] \sqrt{3^{x} } \div \sqrt{3} = 3[/tex]
This is because x to the power of 1/2 is the same as the square of x.
multiply both sides by sqrt3
[tex] \sqrt{3^{x} } = 3 \sqrt{3} [/tex]
square both sides
[tex]3 ^{x} = (3)^{2} ( \sqrt{3} )^{2} [/tex]
simplify
[tex]3 ^{x} = 9 \times 3[/tex]
3 to the power of x is equal to 27
3 cubed (to the power of 3) is 27
so x is equal to 3.
hope i helped, and good luck :)

on the x-axis.
The midpoint M is
D. M lies on the (select), since the y-coordinate is....
Help asap please
Answer:
Use the midpoint formula
Step-by-step explanation:
(-6 + 0 ) ÷ 2 , (-3 + 3) ÷ 2
M = ( -3 , 0) which lies on the x axis
The midpoint M of ST lies on x axis is true
the midpoint M is (-3,0)
M lies on x axis because the y coordinate is 0
Given :
ST has endpoints S(-6, -3) and T(0,3)
Lets find out the midpoint M using midpoint formula
[tex](\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )[/tex]
Here our (x1,y1) is (6,-3) and (x2,y2) is (0,3)
Now apply the midpoint formula to find out midpoint M
[tex](\frac{-6+0}{2}, \frac{-3+3}{2})\\(-3,0)[/tex]
So the midpoint M is (-3,0)
M lies on x axis because the y coordinate is 0

What is the equation of the line that passes through the point (-3, 2) and
has a slope of -3?
Answer:
y= -3x -7
Step-by-step explanation:
You can either use y= mx+b or y-y1=m(x-x1)
I will use y= mx+b
y=mx+b
(-3,2) = (x,y) = -3 is x and 2 is y
-3 =m= slope
y=mx+b
2=-3(-3)+b
2= -3 x-3 +b
2= 9+b
you then subtract 9 on both sides because now 9 is positive so you subtract it.
2=9+b
-9 on both sides
-7= b and the final answer is above

The measure of two side of a triangle are given if p is the perimeter and p=18x+9y find the measure of the third side
Answer:
10x + 6y
Step-by-step explanation:
Let t = length of the third side
3x + 4y + 5x - y + t = 18x + 9y
8x + 3y + t = 18x + 9y
t = 10x + 6y
