Answer:
The rate of change is also called the slope. The slope is -2
Step-by-step explanation:
Find 2 points on the line. I am going to use the points (0,5) and (4, -3). the rate is the change in y over the change in x. From the two points, my values are -3 and 5. The x values are 4 and 0.
To find the change, I subtract the y values and the x values.
[tex]\frac{-3-5}{4-0}[/tex] = [tex]\frac{-8}{4}[/tex] = -2
Answer: -2
Step-by-step explanation: The rate of change is also known as the slope!
To find the slope, you need to find the rise/run.
Let's pick two points ( 0,5) ( 4, -3)
You see that the y goes down by 8 and the x goes right by 4, so the rate of change is -8/4 = -2

7. Population Growth The population of a southern city
follows the exponential law.
(a) If N is the population of the city and is the time in
years, express N as a function of t.
(b) If the population doubled in size over an 18-month
period and the current population is 10,000, what will
the population be 2 years from now?
15
a) If N is the population of the city and is the time in years, N expressed as a function of t is; N(t) = N₀*e^(kt)
b) The population 2 years from now will be; 25198 people
How to solve the exponential growth model?The general formula for exponential growth model is;
N(t) = N₀*e^(kt)
where;
f(x) is exponential growth function
N₀ is initial amount
t is time
k is constant
a) We are told that;
N is the population of the city.
t is the time in years
Thus, N expressed as a function of t is;
N(t) = N₀*e^(kt)
b) We are told that the population doubled in size over an 18-month
period . Thus, the equation would now be;
N(t) = N₀*2^(t/18)
Thus, if the current population is 10000, then it means that 2 years from now, we will have;
N(2) = 10000 * 2^(24/18)
I used 24 because 2 years is 24 months
Thus;
N(2) ≈ 25198 people

The Cp and Cpk values indicate that the process is capable of meeting the specifications for relative humidity in the greenhouse.
What is relative humidity?The amount of water vapor in the air as compared to the maximum amount that it can contain at a certain temperature is known as relative humidity. It is computed as a percentage by dividing the actual amount of water vapor in the air by the maximum amount of water vapor the air can contain at the same temperature, then multiplying the result by 100. For instance, if the air can hold 10 grams of water vapor at a certain temperature and there are only 5 grams of water vapor present, the relative humidity would be 50%. High relative humidity can be uncomfortable and promote the development of mold and other microorganisms.
How to solve?
The mean is (60+78+70+84+81+80+85+60+88+75)/10 = 76.8
The standard deviation is sqrt(((60-76.8)^2+(78-76.8)^2+(70-76.8)^2+(84-76.8)^2+(81-76.8)^2+(80-76.8)^2+(85-76.8)^2+(60-76.8)^2+(88-76.8)^2+(75-76.8)^2)/10) = 6.9
Cp = (85-65)/(66.9) = 0.56
Cpk = min((85-76.8)/(36.9), (76.8-65)/(36.9)) = min(0.86, 0.71) = 0.71

how much is 1kg of corn plus 1 cup of precooked corn ??
Answer:
Step-by-step explanation:
It is not possible to accurately compare the weight of 1 kilogram of corn to 1 cup of precooked corn because the weight of the corn will change after it is cooked. Corn is composed of water, starch, and other nutrients, and the weight of the corn will change depending on how much water is retained in the kernels.
For example, 1 cup of uncooked corn kernels (about 168 grams) will yield about 1 1/4 cups of cooked corn (about 210 grams), while 1 cup of precooked corn (about 160 grams) will yield about 1 cup of cooked corn (about 160 grams).
Therefore, the weight of 1 kilogram of corn (about 1000 grams) is significantly greater than the weight of 1 cup of precooked corn (about 160 grams). It is not possible to accurately compare the weight of these two quantities because they are in different states (raw versus cooked) and have different densities.

A square is inscribed in a circle. Write the area of the square as a function of the radius.
Area will be 2[tex]r^{2}[/tex]
What is area?Area is the entire amount of space occupied by a flat (2-D) surface or an object's form.
Given radius of circle is r
Then area of circle=π[tex]r^{2}[/tex]
The diagonal of the square is comparable to the diameter (2r) of the circle since two opposing corners of the square contact it.
Now, we will set up Pythagoras' Theorem to determine one side of the square:
[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]
Since it is a square a=b which means all the sides are same
∴2[tex]a^{2}[/tex] = [tex]c^{2}[/tex]
We know c, which is 2r, the diagonal.
∴2[tex]a^{2}[/tex] = [tex](2r)^{2}[/tex]
⇒[tex]a^{2}[/tex] = 2[tex]r^{2}[/tex]
We can leave it as [tex]a^{2}[/tex]
since a is one side of the square and [tex]a^{2}[/tex] would be the area of the square.
So the area of the square =2[tex]r^{2}[/tex]

Find the values of the variable in the parallogram . please!
The values of the variables x, y, z in the parallelogram are x=31, y=153, z=96.
What is a parallelogram?In Euclidean geometry, a parallelogram is a simple (non-self-intersecting) quadrilateral with two sets of parallel sides. Both the congruence of opposite sides and the congruence of opposite angles require the Euclidean parallel postulate, or one of its equivalent formulations, and neither condition can be proved without it.
The values of the three supplied variables x, y, and z in the parallelogram are given to us.
Let's abbreviate the parallelogram, which is depicted in the attached image, ABCD.
Here,
m∠CAB = 31°, m∠ABC =96°.
Since CD and AB are parallel, AC is a transversal now. So,
m∠CAB =m∠ACD
m∠ACD=31°
x=31
From the ΔABC we have,
m∠ABC +m∠ACB+m∠BAC=180°
96°+Y+31°=180°
y+127°=180°
y=153°
y=153
And also we know that the measure of opposite angles in a parallelogram are always equal.
So, m∠ADC=m∠ABC
z=96°
z=96
Therefore, the required values of x, y, z are 31, 153, 96.

Last month, Cho opened a checking account. Since then, he withdrew 21 dollars, which was 84% of the balance. How much did
Cho have in the account last month?
Answer:25$
Step-by-step explanation: 21$ is 84% of how much money Cho had last month. So we need to find 100%. You can use a proportion which makes it easier to solve in my opinion. The proportion is 21 over x = 84/100. x is the amount of money Cho had last month which we don't know. 84/100 is 84% out of 100% since any percent is always out of 100. If we cross-multiply and make the proportion into an equation. The equation: 84*x=21*100 which simplifies into 84x=2100. If you do 2100/84, you would get 25 which is x which is the amount of money Cho had last month.

Work out the lowest integer value that m can take if 7m+5>49-3m
The lowest integer value m can take in the inequality 7m + 5 > 49 - 3m is 5.
How to solve inequality?In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.
In other words, Inequalities are mathematical expressions involving the symbols >, <, ≥ and ≤.
Therefore, let's solve the inequality for the lowest integer value of m
7m + 5 > 49 - 3m
add 3m to both sides of the inequality
7m + 5 > 49 - 3m
7m + 3m + 5 > 49 - 3m + 3m
10m + 5 > 49

A blimp is flying to cover a football game. The pilot sights the stadium at a 7° angle of depression. The blimp is flying at an altitude of 400 m. How many kilometers is the blimp from the point 400 m above the stadium?
To find the distance from the blimp to the stadium, we can use the tangent function and the information given in the problem. The tangent of an angle is defined as the ratio of the opposite side to the adjacent side in a right triangle. In this case, we can use the angle of depression to the stadium, the altitude of the blimp, and the distance from the blimp to the stadium to form a right triangle.
We can then use the tangent function to find the distance from the blimp to the stadium as follows:
tan(7°) = opposite/adjacent
opposite = tan(7°) * adjacent
opposite = tan(7°) * 400 m
opposite = 0.1214 * 400 m
opposite = 48.56 m
To convert this distance from meters to kilometers, we can divide the distance in meters by 1000, as follows:
Distance in kilometers = 48.56 m / 1000
