12>13 X
13+5=18
18>13 YES
13+7=20

That's population of turtles in a lake is estimated at 1,000. The population projected to increase 12% per year.
Answer:
(1,000 * (100 + 12))/100 = 1,120 - 1,000 = 120 turtles/ per year
Step-by-step explanation:
The exponential function which can be use to identify the monthly growth is,
⇒ y = 1000 (1.12)¹²ⁿ
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
We have to given that;
That's population of turtles in a lake is estimated at 1,000.
And, The population projected to increase 12% per year.
Hence, The exponential function which can be use to identify the monthly growth is,
⇒ y = 1000 (1 + 12/100)¹²ⁿ
⇒ y = 1000 (1 + 0.12)¹²ⁿ
⇒ y = 1000 (1.12)¹²ⁿ
Thus, The exponential function which can be use to identify the monthly growth is,
⇒ y = 1000 (1.12)¹²ⁿ

What are the solutions of the equation?
y=-7(x-3)(x+4)
Answer:
{-4, 3}
Step-by-step explanation:
To find "solutions," you must set this function equal to zero:
y = -7(x - 3)(x + 4) = 0
and then set each factor equal to 0 separately and solve each resulting equation for x:
x - 3 = 0 yields x = 3, and
x + 4 = 0 yields x = -4

mr davis collected donations for charity. the amounts given by each donor is listed below. what is the range? 50, 52, 64, 32, 22, 80, 48, 30, 60
Answer:
10
Step-by-step explanation:
y = -x + 10 and y = 2x + 4
Answer:
X=2, y=8
Step-by-step explanation:
Y=-x+10 equation 1
y=2x+4 equation 2
-x+10=2x+4. Substitute y of first equation into 2nd equation
-x-2x+10=4
-3x=4-10
-3x=-6
x=2
solve for y by inserting x value into either equation
y=-x+10
y=-2+10
y=8
check answer
y=2x+4
8=2(2)+4
8=4+4
8=8
Solve for x
30=-5(6x+6)
Answer:
x = -2
Step-by-step explanation:
30=-5(6x+6)
step 1 distribute the -5
-5 * 6x = -30x
-5 * 6 = -30
we now have 30 = -30x - 30
step 2 add 30 to each side
30 + 30 = 60
-30 + 30 cancels out
we now have 60 = -30x
step 3 divide each side by -30
-30x/-30 = x
60 / -30 = -2
we're left with x = -2
If L | | m and m<8 = 109°, what is m<5
Answer:
m∡5 = 71°
Step-by-step explanation:
m∡8 = m∡6
m∡6 + m∡5 = 180
180 - m∡6 = m∡5
180 - 109 = 71
Answer:
the measurement of angle 5 is 71
Step-by-step explanation:
m∡8 = m∡6
M∡6 + m∡5 = 180
180 - m∡6 = m∡5
180 - 109 = 71

Write the equation in point-slope form of the line that passes through the given point and has the given slope: (-2, -1); m=-3
Answer:
y+1=-3(x+2)
Step-by-step explanation:
point-slope form is the formula y-y1=m(x-x1), where (x1, y1) is a point and m is the slope
we are given a point (-2, -1) and a slope of -3
all we really need to do is substitute the given into the formula
remember: since the formula gives subtraction, we're going to be subtracting, even though we have negative numbers
substitute -2 as x, -1 as y and -3 as m
y--1=-3(x--2)
we can simplify this equation:
y+1=-3(x+2)

What’s rate of change
Answer:
Rate of change is used to mathematically describe the percentage change in value over a defined period of time, and it represents the momentum of a variable. The calculation for ROC is simple in that it takes the current value of a stock or index and divides it by the value from an earlier period.
Answer:A rate of change is a rate that describes how one quantity changes in relation to another quantity. If x is the independent variable and y is the dependent variable, then. rate of change=change in ychange in x. Rates of change can be positive or negative.

A study with a sample that is very different from the population is biased
What is Population Density?The population density, or the number of people divided by the area's size, is determined by the number of people who reside there. Numerous creatures' distribution, growth, and migration can all be explained by population density.
Population density = number of people / the area they occupy
Given data ,
A study with a sample that is very different from the population is J. biased.
In statistical terms, bias refers to any systematic error or deviation from the true value that can occur in a study. When a study is biased, the results may not be representative of the population and may not be generalized other settings.
Results from a research may be skewed if the sample chosen is considerably different from the population. Both experimental and observational research may experience this. As a result, alternatives F and G do not offer sufficient details to assess the study's objectivity.

Answer:
C. The scale factor is less than one.
Step-by-step explanation:
By definition, similar triangles have equal angles and proportional corresponding side lengths. Thus, A, B, and D are all mutually exclusive, leaving C the only possible answer. Upon further inspection, the scale factor is indeed greater than one (each side length is scaled by a factor of two, which is large than one)

the range of y=|x| is not all real numbers its [0,inf)
PLS HELP I DONT KNOW IT
Answer:
D
Step-by-step explanation:
Since the side length of the square is (2x+5), and squares have equal sides, then you have to do (2x+5)(2x+5). You would get 4x^2+20x+25. That means the answer is D.

the conjunction, x<3 and x>-1, may be written -1
===========================================================
Explanation:
The first thing to do is to swap the positions of the x < 3 and the x > -1
So you'll end up with x > -1 and x < 3
Now focus entirely on x > -1. Swap the left and right sides, and also swap the inequality sign. So we end up with -1 < x
That means the "x > -1 and x < 3" is the same as "-1 < x and x < 3"
From here, we collapse the two inequalities to form the compound inequality -1 < x < 3
We can say "x is between -1 and 3, excluding either endpoint".
