The world population at the beginning of 1980 was 4.5 billion. Assuming the population continued to grow at the rate of approximately 1.3% per year, find a function Q(t) giving the population of the world (in billions) as a function of time t (in years)
Answer:
The function Q(t) = 4.5 billion (1.013)^t will give the population in t years
Step-by-step explanation:
Here, we want to write a function
The growth percentage is 1.3% = 1.3/100 = 0.013
The function Q(t) will be an exponential function and it will be represented as;
Q(t) = I ( 1 + r)^t
where I is the initial world population at 1980 = 4.5 billion
r is the growth percentage = 1.3% = 0.013
t is the time in years
Substituting these values, we have;
Q(t) = 4.5 billion (1 + 0.013)^t
Q(t) = 4.5 billion (1.013)^t
Adjacent angles that form a linear pair are supplementary angles. True or false?
Answer:
FALSE
Step-by-step explanation:
Answer:
Step-by-step explanation:
It's true. If you have a straight line and you put the endpoint of a ray on that line and let the ray go in the direction it is pointing, 2 angles will be formed unless the ray is part of the line.
The way the question is worded, you have a linear pair which means there are 2 distinct angles whose vertex is on a line.
That's the very definition of supplementary.

In the figure, m∠2=(20x+52)° and m∠7=(40x-48)°
For what value of x is m || n ?
Enter your answer in the box.
x = ___
Answer: x=5 m is parallel to n
Step-by-step explanation:
∠2 and ∠7 are alternate exterior angles so they are equal.
So you can create the equation
40x-48 = 20x+52 Subtract 20x from both sides. Add 48 to both sides.
20x = 100
x = 5
if you need m∠2 Substtute 5 for x in 20x+52
20(5) + 52 = 100 +52 m∠2= 152°
m∠7 40(5) - 48 = 200-48 m∠7= 152°
Answer:
x=5 and m is parallel to n

You have space in your garden for 50 small flowering bulbs. Bulb A cost $0.45 each and
bulb B cost $0.65 each. Your budget allows you to spend $26.90 on bulbs. How many of bulb A and how many of bulb B can you buy?
_______number of bulb A
_______number of bulb B
Answer:
A = 28
B = 22
Step-by-step explanation:
All money will be recorded in pennies
Let A = the 45 Bulb
Let B = the 65 bulb
A + B = 50 (1)
45A + 65B = 2690 (2)
Multiply (1) by 45 and subtract that from (2)
45A + 65B = 2690
45A + 45B = 2250 Subtract
20B = 440
B = 22
A + B = 50
A + 22 = 50
A = 50 - 22
B = 28
Check
45*28 + 22* 65 =
1260 + 1430 = 2690

In the game of Pick-A-Ball, there are 10 colored balls: 2 red, 4 white, and 4 blue. The balls have been placed into a small bucket, and the bucket has been shaken thoroughly. You will be asked to reach into the bucket without looking and select 2 balls. Because the bucket has been shaken thoroughly, you can assume that each individual ball is selected at random with equal likelihood of being chosen. It is common in games of chance to be rewarded for obtaining unlikely results. For example, in the game of poker, hands that are less likely to occur tend to trump hands that are more likely to occur. That same concept applies in this game. It costs $10 to play Pick-A-Ball, and your prize is the reciprocal of the probability of obtaining your exact sequence of results, expressed in dollars. For example, if the probability of obtaining your exact sequence of results is 0.10, your prize is 1/0.10 and you break even. Therefore, to make a positive profit from playing Pick-A-Ball, the probability of obtaining your results must be ower than 0.10. When you reach into the bucket, your result is based on a simulation. In a simulation, random events are modeled in such a way that the simulated outcomes closely match real-world outcomes. In this simulation, your result is simulated based on the robabiliies of obtaining a ball of a particular color. Now, close your eyes! Reach into the bucket, and pick a ball.
Hello,
This question you posted is incomplete but I was able to get the complete question. I hope it would be of help to you!
1. What is the probability of selecting the color of ball that you just selected?___
Don't put your first ball back in the bucket now reach again, no peeking and pick your second ball.( Click the pick a ball icon to simulate reaching into the bucket and select your next ball)
2. What is the probability of selecting the color of ball that you just did_____
3.what is the probability of obtaining your exact sequence of result?____
4. What is your prize____
5. What is your profit from pick a ball___
Answer:
1. The probability of selecting the color of ball that you picked. (White)
The color is white. And total balls are 10
= 4/10
= 0.4
2. After first ball was picked out, you now have 3 whites left and total balls 9. probability of selecting the color of ball that you picked = 3/9
= 0.3333
3. Probability of getting exact sequence
= 0.3333x0.4
= 0.1333
4. The prize = 1/0.1333
= 7.5
5. The price would be 7.5 - 10
= -2.5

Fill in the blank. In the triangle below, zº = ___º
Answer:
[tex]\huge\boxed{43 \textdegree}[/tex]
Step-by-step explanation:
We can use basic angle relationships to find the measure of z.
We know that all angles in a triangle will add up to 180°. Since we already know two out of the 3 angles (47° and 90° - right angles are always 90°) we can add those two up and subtract from 180 to find out the missing angle length.

Enter your answer as equations separated by a comma.
Answer:
AC = 30 in
m∠B = 36,9°
m∠A = 53,1°
Step-by-step explanation:
1 AC
You gan get AC with the pythagorean theorem:
a²+b²=c²
We are looking for side b of the triangle, so the equation is rearranged for b.
BC²+AC²=AB² | -BC²
AC²=AB²-BC²
AC=√(AB²-BC²)
Now the given values are used:
b=√(50²-40²)
b=√(2500-1600)
b=√900
b=30 in
2 m∠B
This angle can be calculated using the sine law:
sine(angle)=opposite cathete/hypothenus
We are looking for angle m∠B of the triangle.
sin(m∠B)=AC/AB
sin(m∠B)=30in/50in
sin(m∠B)=0,6
m∠B=36,9°
3 m∠A
This angle can be calculated using the sine law:
sine(angle)=opposite cathete/hypothenus
We are looking for angle m∠A of the triangle.
sin(m∠A)=BC/AB
sin(m∠A)=40in/50in
sin(m∠A)=0,8
m∠A=53,1°

m∠AGF + m∠CGE + m∠AGC = 180° ( linear pair )
84° + 64° + m∠AGC = 180°
148° + m∠AGC = 180°
m∠AGC = 180 - 148
m∠AGC = 32°
As m∠AGC and m∠DGB are vertically opposite angles , their angle measure will be equal .
Which means :-
m∠AGC = m∠DGB ( vertically opposite angles )
m∠DGB = 32°Therefore :-try:- m∠DGB = 32° Reason :-vertical anglesIn the diagram shown, if m<AGF = 64°, m<CGE = 84°, then m<DGB = 32°
From the figure shown:
m<AGF = 64° (Given)
m<CGE = 84° (Given)
m<AGF = m<BGE (Vertically opposite angles are equal)
m<AGF = m<BGE = 64°
m<CGE + m<BGE + m<DGB = 180° (Sum of angles on a straight line)
84 + 64 + m<DGB = 180
148 + m<DGB = 180
m<DGB = 180 - 148
m<DGB = 32°
Therefore, in the diagram shown, if m<AGF = 64°, m<CGE = 84°, then m<DGB = 32°

Use the factor theorem to determine which of the following is a factor of f(x)=x^3+5x2-15x+9
x-2
x+1
x-1
x+2
show work please
x+2
Step-by-step explanation:
x+2
If x = –2 is a zero, then x + 2 = 0, so x + 2 is a factor. Similarly, if x = 1/3 is a zero, then x – 1/3 = 0, so x – 1/3 is a factor. By giving me two of the zeroes, they have also given me two factors: x + 2 and x – 1/3.
A rental car agency charges a flat fee of $32.00 plus $3.00 per day to rent a certain car. Another agency charges a fee of $30.50 plus $3.25 per day to rent the same car.
Answer:
a rental car agency charges a flat rate fee of $32.00 plus $3.00 per day to rent a certain car
c = 32 + 3d
another agency charges a fee of $30.50 plus $3.25 per day to rent the same car
c = 30.50 + 3.25d
the number of days for which the cost are the same means
32 + 3d = 30.50 + 3.25d
by solving we find d = 6 days
A student taking a Calculus class makes the following statement:
”If f(1) > 0 and f(3) < 0, then there exists a number c, between 1 and 3 such that f(c) = 0.”
Is the statement true? If it’s true, explain why, if it is false, explain why, or give an example that disproves it.
Explanation:
Imagine that f(x) was a road without any gaps. The road can be straight or it can be curved somehow.
Now imagine that a horizontal line is the border between two countries. The country up north is the positive country and the southern country is negative.
f(1) > 0 means we're in the northern country since f(x) is positive here
then f(3) < 0 means we're now in the southern negative country
Somewhere along the road we must have crossed the border at least one time. This must be the case because the road does not have any gaps in it and we cannot teleport. This is what it means to be a continuous function. To draw a continuous curve, you cannot lift your pencil up.
So because f(x) transitions from positive to negative, this means f(x) = 0 at some point at least once. So that's why there exists a c such that f(c) = 0
