Today, the population of Canyon Falls is 22{,}50022,50022, comma, 500 and the population of Swift Creek is 15{,}20015,20015, comma, 200. The population of Canyon Falls is decreasing at the rate of 740740740 people each year while the population of Swift Creek is increasing at the rate of 1{,}5001,5001, comma, 500 people each year. Assuming these rates continue into the future, in how many years from today will the population of Swift Creek equal twice the population of Canyon Falls
Answer:
10 years
Step-by-step explanation:
Given :
Population of Canyon falls = 22500
Rate of decrease = 740 per year
Population after x years :
f(x) = 22500 - 740x ; x = number of years
Population of Swift Creek = 15200
Rate of Increase = 1500 per year
Population after x years :
f(x) = 15200 + 1500x ; x = number of years
Number of years when, population of swift creek will be twice that of Canyon falls
15200 + 1500x = 2(22500 - 740x)
15200 + 1500x = 45000 - 1480x
15200 - 45000 = - 1480x - 1500x
-29800 = - 2980x
x = 29800 / 2980
x = 10

A soccer ball is kicked from the ground at an upwards velocity of 90 feet per second. The equation h(t)=-16t^(2)+90t gives the height of the ball after t seconds. How many seconds will it take for the ball to reach its maximum height?
I need help figuring this out to help my grade
Answer: 2.81 s
Step-by-step explanation:
Given
Ball is kicked upward with velocity [tex]u=90\ ft/s[/tex]
Height of the ball is given by the function [tex]h(t)=-16t^2+90t[/tex]
Derivative of a function gives the maxima or minima at certain point
[tex]\Rightarrow \dfrac{dh}{dt}=-32t+90\\\\\Rightarrow \dfrac{dh}{dt}=0\\\\\Rightarrow -32t+90=0\\\\\Rightarrow t=\dfrac{90}{32}\\\\\Rightarrow t=2.81\ s[/tex]
Thus, it takes ball 2.81 s to reach the top.

If this sun is 66° above the horizon, find the length of the shadow cast by a building 61 feet tall. Round your answer to the nearest tenth.
Answer:
27.2 ft
Step-by-step explanation:
We solve using the Trigonometric function of tan
tan θ = Opposite/Adjacent
θ = 66°
Opposite = Height of the building = 61 ft
Adjacent = Length of the shadow = ? = x
tan 66 = 61/x
Cross Multiply
tan 66 × x = 61
x = 61 ft/tan 66
x = 27.158949804 ft
Approximately = 27.2 ft
The length of the shadow = 27.2 ft
the product of two consecutive positive odd integers is 2499 find the bigger integer
Step-by-step explanation:
Consecutive odd integers are integers that take on the form n, n + 2, n +4, n + 6, and so on, where n is odd.
Now, Product of two consecutive positive odd integers = 2499
=>n*(n+2) = 2499
=>n^2+2^n-2499=0
=>n^2+51^n-49^n-2499=0 =>n(n+51)-49(x+51)=0
=>(n+51)(n-49)=0
=>n=49 (n is not equal to -51 which is negative integer).
So,bigger integer =(n+2)=49+2=51.

Answer:
40 cm
Step-by-step explanation:
volume = length x width x height
10,000 = 25 x 10 x h
h = 10,000/ (25 x 10)
h = 10,000 / 250
h = 40 cm

Answer:
Given a line segment AB
open the compass more than half of the distance between A and B, and scribe arcs of the same radius centered at A and B.
Call the two points where these two arcs meet C and D. Draw the line between C and D.
CD is the perpendicular bisector of the line segment AB. Call the point where CD intersects AB E.
Step-by-step explanation:
for more help please follow
Answer:
Follow the steps below to construct a perpendicular bisector of a line segment.
Step 1: Draw a line segment XY of any suitable length.
Step 2: Take a compass, and with X as the center and with more than half of the line segment XY as width, draw arcs above and below the line segment.
Step 3: Repeat the same step with Y as the center.
Step 4: Label the points of intersection as 'P' and 'Q'.
Step 5: Join the points 'P' and 'Q'. The point at which the perpendicular bisector PQ intersects the line segment XY is its midpoint. Label it as 'O'.

One x-intercept for a parabola is at the point
(1,0). Use the factor method to find the other x-
intercept for the parabola defined by this
equation:
y = 2x2 - 6x + 4
Answer:
x-intercept (2, 0)
Step-by-step explanation:
y = 2x² - 6x + 4
Factor
(2x - 2)(x - 2) = 0
2x - 2 = 0
2x = 2
x = 1
x-intercept (1, 0)
x - 2 = 0
x = 2
x-intercept (2, 0)
By using the factor method,
the other x-intercept of the parabola is (2, 0).
What is parabola?A parabola is a curve drawn in a plane. Where any point is at an equal distance from a fixed point (the focus) and a fixed straight line (the Directrix ).
Given:
One x-intercept for a parabola is at the point (1,0).
In factor form : (x - 1)
And the quadratic function,
y = 2x² - 6x + 4.
To find the factor of the equation:
2x² - 6x + 4 ÷ (x - 1)
We get,
(2x - 4) = 0
x = 4/2
x = 2
The other intercept of the parabola is (2, 0).
Therefore, the other x-intercept of the parabola is (2, 0).

A researcher selects a sample of participants to test for differences in employment rates among part-time and full-time teachers. Because there are many more women in teaching jobs than men, the researcher selected more women than men for her study to ensure that it represented the actual distribution of men and women teachers in the job sector. Which type of quota sampling was used in this example
Answer: proportionate
Step-by-step explanation:
Proportional quota sampling is when the total number of people that are to be surveyed are decided in advance. This form of sampling is usually used in opinion polls and surveys.
Since due to the fact that there are many more women in teaching jobs than men, the researcher selected more women than men for her study to ensure that it represented the actual distribution of men and women teachers in the job, then this was decided in advance and indicates the proportionate quota sampling.

The x-intercept is when y=0. It is the point on the x-axis. Solve for x when y=0 in the first equation.
2x + 3(0) + 6 = 0
2x = -6
x = -3
x-intercept is (-3, 0).
The line we want has the same slope as the second equation because it is parallel. From the second equation,
-5y = -2x + 7
y = (2/5)x - (7/5)
The slope is 2/5.
Using the x-intercept and slope, along with the general form of the line y = mx + b , we can solve for b.
y = mx + b
0 = (2/5)(-3) + b
0 = (-6/5) + b
(6/5) = b
The equation we want is
y = (2/5)x + (6/5)

A rectangular pen for pigs that will enclose a total area of 169 square feet. What is the least amount of fencing that is needed?
Answer:
The answer is below
Step-by-step explanation:
Let x represent the length of the rectangular pen and y represent the width of the rectangular pen. Since the total area of the pen is 169 ft², hence:
Area = length * width
169 = xy
y = 169/x
Also the perimeter of the rectangular pen is:
Perimeter (P) = 2(length + width)
P = 2(x + y)
P = 2x + 2y
P = 2x + 2(169/x)
P = 2x + 338/x
The least amount of fencing is at dP/dx = 0, hence:
dP/dx = 2 - 338/x² = 0
338/x² = 2
2x² = 338
x² = 169
x = 13 feet
y = 169 / x = 169/13 = 13 feet
The least amount of fencing = P = 2(x + y) = 2(13 + 13) = 52 feet

Answer:
6
Step-by-step explanation:
(whole secant) * (external part) = (tangent)^2

(2+ ML) * 2 = 4^2
(2+ ML) * 2 =16
Divide each side by 2
(2+ ML) = 8
Subtract 2 from each side

Exponents of 1/2 are the same as square roots

If the exponent was say 1/3, then we'd be taking a cube root
