A population numbers 10,000 organisms initially and decreases by 4.1% each year.
Suppose P represents population, and t the number of years of growth. An exponential model for the
population can be written in the form P = a b where
P=
Answer:
[tex]y = 10000 * 0.959^t[/tex]
Step-by-step explanation:
Given
[tex]a = 10000[/tex]
[tex]r = 4.1\%[/tex]
Required
Express as an exponential function [tex]y =ab^t[/tex]
First, we calculate the value of b;
Since the population decrease, then
[tex]b = 1 - r[/tex] --- This represents decrement of decay factor
Substitute [tex]r = 4.1\%[/tex]
[tex]b = 1- 4.1\%[/tex]
[tex]b = 0.959[/tex]
So:
[tex]y =ab^t[/tex] becomes
[tex]y = 10000 * 0.959^t[/tex]

Answer:
60 degrees
Step-by-step explanation:
On the diagram, we can see that the two angles have a dash on each of them. This means that they have the same measure.
So, if angle ABD is 60 degrees, then angle DBC would also be 60 degrees.
I hope this helps!

Step-by-step explanation:
The period is . On a coordinate plane, the points on a function curve are shown. The curve crosses the y-axis at (0, 5) and then decreases to the minimum. The minimum is at (0.748, 2) and the maximum is at (1.870, 6). After the green point, the curve increases and then decreases again. A green point is at y = 4.
The Period of the Function Curve with the green point at y = 4 on the given coordinate plane is; 2.244
How to find the period of a wave?We are given;
Minimum Point; (0.748, 2)
Maximum Point; (1.870, 6)
The green point is the lowest point and from drawing the curve, we see that the next highest point coordinate is (4.114, 6).
The period is the x-coordinate distance between the two highest points. Thus;
Period of wave = 4.114 - 1.87
Period of wave = 2.244

Answer: 7. x= 26, 9. x=11/y=3
Step-by-step explanation: Sorry for the terrible photo quality. Comment if you need more help : )
So, for the first examples given set all of the equations as equal to the other angle equation given.For problems like number 9, solve for the x's first (or whichever variable there's more of) you should solve for the x's like you did for the first problem, then set the equation to an A+B=180 format. The reason for this is two angles (in some cases more) on a straight line together will always equal 180 degrees. For 10. set the equations with x in them to that A+B=180 format. Then once you've found x plug it into 6x-7. When you have that answer set 8y+17 equal to the answer you got and solve for y.For 11 and 12. These ones can be a bit more complicated because of their visual appearance, however you just need to combine the earlier steps taken to solve the first couple of equations. Beginning with 12. If you ever see a Z pattern, know that the sides facing > and < ( the inside angles of the Z) are equal to each other. So you set the equations with x equal to each other, and once you get x plug it into the equation inside of the triangle. Since you've already been given 90, set the equation up like this: 43+90+(7y-20)=180. Because all the angles in a triangle are equal to 180 degrees. Then just solve for y. y=9Lastly for number 11. This one is by-far the hardest of all of them. You have to adjust how you look at the problem. You'll see that if you add (3x+49) it's actually congruent to (7x-23). once you figure out x you should then plug x into 3x giving you 54. The set up the equation like this 11y-1=54. That will give you y=5.Simplify the following expressions by combining like terms. Then, tell if the expressions are equivalent.
3r + 10 + r -8 and 8 + 2(2r) - 6
Answer:
2+4r. Expressions are equivalent.
Step-by-step explanation:
3r + 10 + r -8Multiply r and 3
Multiply r and 1
The r just gets copied along.
The answer is r
r
3*r evaluates to 3r
3*r+10 evaluates to 3r+10
3r + r = 4r
The answer is 4r+10
3*r+10+r evaluates to 4r+10
10 - 8 = 2
The answer is 2+4r
3*r+10+r-8 evaluates to 2+4r
The final answer is
2+4r
8 + 2(2r) - 6
Multiply r and 2
Multiply r and 1
The r just gets copied along.
The answer is r
r
2*r evaluates to 2r
Multiply 2 and 2r
Multiply 1 and r
The r just gets copied along.
r
2*(2*r) evaluates to 4r
8+2*(2*r) evaluates to 8+4r
8 - 6 = 2
The answer is 2+4r
8+2*(2*r)-6 evaluates to 2+4r
The final answer is
2+4r

Solve for the unknown values.
Answer:
y=45° x=81°
Step-by-step explanation:
the 2 angles across the outside angles sum up to the given number so just subtract 95-50= 45, with that we know subtract from the total sum of every triangle which is 180. So we add the 2 angles we have now, 50+45=99. Now we subtract, 180-99= 81.
