"The graph below shows the population of mice in an ecosystem where the mice are not allowed to enter or leave.
Which best describes the population at point A?
A.The death rate is higher than the birthrate.
B.The population is decreasing.
C.The birthrate is higher than the death rate.
D.It has reached carrying capacity"
Answers
The point marked A is the point where the birth rate is higher than the death rate.
What is birth rate/ death rate?The term birth rate refers to the rate at which new organims are introduced into the population and the death rate refers to the rate at which individuals exit in the population.
In this case, when we observe the graph, we can see that the point marked A is the point where the birth rate is higher than the death rate.

What is the Pythagorean theorem?Pythagorean theorem states that in the right angle triangle, the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
Use the Pythagorean theorem to calculate the length of AB as below,
OB² = AB² + OA²
(BC + OC)² = AB² + OA²
(27 + 24)² = AB² + 24²
AB² = 51² - 24²
AB = 45 units
Therefore, the correct option is A. The value of length AB is 45.

Answers
99.2/62 = x
The answer is 1.6 hours.
Deshaun drove at a speed of 62 miles per hour for 99.2 miles. To calculate the time spent driving, use the formula Time = Distance / Speed. The time taken for his drive is approximately 1.6 hours.
The question pertains to calculating the driving time given the speed and distance traveled by Deshaun in his new car. He drove at a speed of 62 miles per hour for 99.2 miles. To find out how many hours he drove, we use the formula for time which is:
Time (t) = Distance (d) / Speed (v)Here, the distance d is 99.2 miles and the speed v is 62 miles per hour.
So we calculate the time t as follows:
t = 99.2 miles / 62 miles per hourThe time taken by Deshaun for his drive is approximately 1.6 hours.

eremy is working at 2 jobs to save money for his college education. He makes $8 per hours working for his uncle at Pizza Pie busing tables and $10 per hour tutoring peers after school in math. His goal is to make $160 per week. Part c- After researching the costs of colleges, Jeremy decides he needs to make more than $160 each week. Write an inequality in two variables to represent the amount of money Jeremy needs to make. Then graph.
Answers
Final answer:
Jeremy needs to create an inequality to represent his new earning goal higher than $160 a week, leading to the inequality 8x + 10y > 160. This can be graphed by first converting to intercept form, plotting the intercept and slope, drawing a dashed boundary line, and shading the region above this line.
Explanation:
Jeremy is working two jobs to save for his college education and needs to create an inequality to represent the amount he needs to make each week, now more than $160. Let's denote the number of hours Jeremy works busing tables as x and the number of hours he spends tutoring as y. He makes $8 per hour busing tables and $10 per hour tutoring.
To express Jeremy's goal of making more than $160 a week, we can write the following inequality:
8x + 10y > 160
To graph this inequality:
First, rewrite the inequality as y > (-4/5)x + 16 to get the intercept form.
Plot the y-intercept at (0, 16) on the graph.
Use the slope of -4/5 to determine another point. From (0, 16), move 5 units to the right (positive x-direction) and 4 units down (negative y-direction), then plot this second point.
Draw a dashed line through the two points to represent the boundary of the inequality (dashed because the inequality is strict and does not include the line itself).
Shade above the line to indicate that all solutions to the inequality lie in this area, where Jeremy would be earning more than $160.

B: F(n) = 4+3n
C: F(n) = 3+4n
D: F(n) = 3+4(n-1)******
Answers
Answer:
1. 13, 17 Option D
2. -2 Option B
3. 2 Option C
4. F(n) = 3+4(n-1) Option D
Step-by-step explanation:
1.
Given sequence is: 1, 5, 9....
Common difference = 5-1 = 9-5 = 4
Next term is :
9+4 = 13
and
13+4= 17
So, next two terms are: 13 & 17.
2.
Given sequence is :
102, 100, 98, 96....
Common difference = 100 - 102 = 98 -100 = 96 - 98 = -2
3.
Given rule is :
Aₙ = -14 + (n - 1)(2)
Find the 9th term
so, we put n = 9
A₉ = -14 + (9-1)*2
A₉ = -14 + 8*2 = -14 + 16
A₉ = 2
Ninth term is 2.
4.
Given sequence is:
3, 7, 11, 15.....
Write the nth term
Formula is :
F(n) = a₁ + (n-1)d
Where a₁ is first term
n is number of terms
d is common difference
a₁ = 3
d = 7-3 = 11-7 = 15 - 11 = 4
So nth term is :
F(n) = 3 + 4(n-1)
That's the final answer.

2. -2 Option B
3. 2 Option C

...?
Answers
Answer:
A
C
Step-by-step explanation:
Here we must compare a function and its transformation, we will see that the correct options are A and C.
First, we must define the transformations that we will be using here.
Reflection about the x-axis:
For a function f(x) a reflection about the x-axis is written as:
g(x) = -f(x)
Vertical contraction.
For a function f(x) a vertical contraction of scale factor k is written as:
g(x) = k*f(x)
So here we start with:
ƒ(x)=√x
Then we reflect it about the x-axis to get:
ƒ(x)=-√x
Then we shrink it by a scale factor k = 1/2
ƒ(x) = (-1/2)*√x
From this, we can see that the correct options are:
A. The graph of ƒ(x)=-1/2√x will look like the graph of ƒ(x)=√x but will reflect it about the x-axis and shrink it vertically by a factor of 1/2.
And C is also true, because we have a reflection about the x-axis, the range changed from positive values to negative values, so:
C. ƒ(x)=-1/2√x has the same domain but a different range as ƒ(x)=√x.
Is also a correct option.

Sq root of 2^2 = ?
Well 2 ^2 = 2•2 = 4 and the square root of 4 is 2. So whenever you think of what the opposite of squaring or raising something to the value of 2, the reverse would be taking the square root of the number or expression.
So sq root of 14x • sq. root of 14x = (sq. root of 14x) ^2 which is simply 14x.
The solution is 14x.

2x+6y=13
Next, transfer 2x to the right side and it will look like this:
6y=13-2x
Now, divide both sides by 6, and it will look like this:
y=13-2x
