Hey there!
a) --›initial number = 3750
--›rate = 2.5%
let y be the population t years after 2021
So, y = 3750(1+2.15) ^ t
=> 3750 × 1.0215 ^ t
b) In 2036,
=> t = 2036 - 2021
=> 15
Substitute into the first value
=> 3750 × 1.0215 ^ t
=> 3750 × 1.0215 ^ 15
=> 5159.
Therefore, the population in 2036 would be 5159

Step-by-step explanation:
You pull out the plug from the bathtub. After 40 seconds, there are 13 gallons of water left in the tub. One minute after you pull the plug, there are 10 gallons left.
Assume that the number of gallons varies linearly with the time since the plug was pulled.
Write the particular equation expressing the number of gallons (g) left in the tub in terms of the number of seconds (s) since you pulled the plug.
Answer:
g = -3/20s + 19Step-by-step explanation:
Let's assume this is a function
The points are
(40, 13) and (60, 10)Since it is linear relation, we'll get the slope intercept form
g = ms + b, where g- number of gallons, s- time in seconds, b- y interceptUsing the points, let's calculate the formula
m = (10 - 13)/(60 - 40) = -3/2010 = -3/20*60 + b10 = - 9 + bb = 19So the formula is:
g = -3/20s + 191)

Complete question is;
Peter drew two rays, AC and AP with A as a common endpoint. Which of the following statements
might describe Peter's drawing?
I. AC and AP are parallel.
II. PAC is an angle
III. AC and AP are perpendicular
A. I and II
B. II and III
C. I and 111
D. I, II, and III
Answer:
Option B: II & III
Step-by-step explanation:
We are told that Peter drew two rays which are AC and AP.
We are told that A is a common endpoint.
If A is a common endpoint, it means the 2 rays interaction point at A is at an angle.
The angle could also be 90° which means it's possible that the rays AC and AP are perpendicular.
Thus, the correct statements that describe his drawing are: II & III

find 3 consecutive integers if three times the first integer is two times the third.
Answer:
4, 5, and 6
Step-by-step explanation:
Three Consecutive integers are x, x+1, x+2
We are given 3 times the first integer is 2 times the third
So
3x = 2(x+2)
Solve for x
3x = 2x+4
x = 4 (first integer)
so the 3 integers are 4, 5, and 6

Answer:
139.25 m²
Step-by-step explanation:
Area of the square = 10 * 10 = 100 m²
Radius of the semicircle = 5 m
Area of the semicircle = π(5)²/2 = 39.25 m²
Total area = 100 + 39.25 = 139.25 m²
What must be a factor of the polynomial function f(x) graphed on the coordinate plane below?
A) x – 6
B) x – 3
C) x + 1
D) x + 6
Answer:
D. x + 6
Step-by-step explanation:
In the given graph, we have 3 x-intercepts values, which are points at which the line intercepts the x-axis. They are, -6, -3 and 0.
Each of these x-intercepts can be written as a factor of a polynomial function as follows:
x = -6
x = -6 + 6
x + 6 = 0
x = -3
x = -3 + 3
x + 3 = 0
x = 0
Therefore, the factor of the polynomial function must be: x + 6

The girls varsity basketball team had 850 fans attend their first game of the season. For the second game they had 1037 fans attendance. What was the percentage increase in attendance?
Answer:
22%
Step-by-step explanation:
It's 22% because if we want to find the percent change in something, the formula for that is new number - (minus) old number, than divide by old number, and lastly multiply by 100. So,
1. 1037 - 850 = 187
2. 187 / 850 = 0.22
3. 0.22 x 100 = 22 --> 22%

a rectangle has a length 12 meters and a width of 400 centimeters. what is the perimeter, in cm of the rectangle
Answer:
P= 3200 cm
Step-by-step explanation:
Perimeter = 2(l+w)
In this case since the perimeter has to be in centimeters, we have to change the length of the rectangle to centimeter.
12 meter to centimer = 12 x 100 = 1200 cm
2( 1200 +400)
2 (1600)
= 3200 cm

on algebra, to move something to the other side of the equal sign you must make the variable cancel out.
so, in this case, we will add 2x to cancel out the -2x. after that rules of algebra state whatever we do to one side of the equal sign, we must do to the other. so we get 2x on the left side, resulting in 2x+y=-3

Answer:
B
Step-by-step explanation:
Y-intercept is where a graph crosses the y-axis at x=0
f(x) = 6x^2 + 18x + 3
f(0) = 6(0)^2 + 18(0) + 3 = 3
From the plot, g(x) at x=0 is 6.
So the answer is B. g has a greater y-intercept than f.
For f(x)
[tex]\\ \rm\rightarrowtail y=6x^2+18x+3[/tex]
Put x =0[tex]\\ \rm\rightarrowtail y=6(0)^2+18(0)+3=3[/tex]
Y intercept at 3From the graph
y intercept of g(x)=6
So option B is correct

The data provided is as follows:
Blood Group
