The slope of a linear function represents the rate at which the output variable (y) changes with respect to the input variable (x). The slope is often denoted by the letter "m" and can be calculated using the formula:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are any two points on the line.
To find the slope of Function 1, we can compare the coefficient of x in its equation with the formula for slope. We see that the coefficient of x in y = (4/5)x + 2 is 4/5. Therefore, the slope of Function 1 is 4/5.
To find the slope of Function 2, we can choose any two points from the table and use the slope formula. Let's choose the points (0, 1) and (3, 2.5). Plugging in these values, we get:
m = (2.5 - 1) / (3 - 0) = 1.5 / 3 = 1/2
Therefore, the slope of Function 2 is 1/2.
Comparing the slopes, we can see that the slope of Function 1 (4/5) is greater than the slope of Function 2 (1/2). Therefore, Function 1 has a greater slope than Function 2.
Answer:
Function 1 has the greatest slope.
Step-by-step explanation:
Function 1Function 1 is given in slope-intercept form, y = mx + b, where m is the slope (and b is the y-intercept).
Therefore, the slope of function 1 is ⁴/₅.
Function 2To find the slope of function 2, use the slope formula.
[tex]\boxed{\begin{minipage}{8cm}\underline{Slope Formula}\\\\Slope $(m)=\dfrac{y_2-y_1}{x_2-x_1}$\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ are two points on the line.\\\end{minipage}}[/tex]
Let (x₁, y₁) = (0, 1)
Let (x₂, y₂) = (2, 2)
Substitute the values into the formula:
[tex]\implies m=\dfrac{2-1}{2-0}=\dfrac{1}{2}[/tex]
Therefore, the slope of function 2 is ¹/₂.
Greatest slopeTo determine which function has the greatest slope, rewrite both slopes so that the denominator of the fractions are the same.
[tex]\textsf{Slope of function 1}=\dfrac{4}{5}=\dfrac{4 \cdot 2}{5 \cdot 2}=\dfrac{8}{10}[/tex]
[tex]\textsf{Slope of function 2}=\dfrac{1}{2}=\dfrac{1 \cdot 5}{2 \cdot 5}=\dfrac{5}{10}[/tex]
As 8 is greater than 5, the slope of function 1 is greater than the slope of function 2.

Suppose you physically simulate the random process of rolling a single die. (a) After 1010 rolls of the die, you observe a "one" 44 times. What proportion of the rolls resulted in a "one"? (b) After 2020 rolls of the die, you observe a "one" 22 times. What proportion of the rolls resulted in a "one"?
Answer:
(a) 4.356% (b) 1.089%
Step-by-step explanation:
The rolling of a single die is an example of a discrete uniform distribution, where each of the six possible outcomes has an equal probability of 1/6.
(a) After 1010 rolls of the die, observing a "one" 44 times, the proportion of rolls resulting in a "one" is:
Proportion = Number of "ones" / Total number of rolls
= 44 / 1010
= 0.04356
Therefore, approximately 4.356% of the rolls resulted in a "one".
(b) After 2020 rolls of the die, observing a "one" 22 times, the proportion of rolls resulting in a "one" is:
Proportion = Number of "ones" / Total number of rolls
= 22 / 2020
= 0.01089
Therefore, approximately 1.089% of the rolls resulted in a "one".

a. Monthly payment for the bank's car loan is $407.67
b. Monthly payment for the savings and loan association's car loan is $315.99
c. Total amount paid would be $2,035 less for the bank's car loan than for the savings and loan association's car loan.
What is interest rate?The cost of borrowing money, usually expressed as a percentage of the amount borrowed, is what a lender charges a borrower to use their money. This cost is known as an interest rate.
(a) To find the monthly payment for the bank's car loan, we can use the formula for the present value of an annuity:
[tex]PV = PMT * \frac{1 - (1 + \frac{r}{n})^{(-n*t)}}{\frac{r}{n} }[/tex]
putting the given values,
⇒ [tex]21000 = PMT * \frac{1 - (1 + \frac{0.065}{12})^{(-12*5)}}{\frac{0.065}{12} }[/tex]
Solving for PMT, we get:
PMT = $407.67
Therefore, the monthly payment for the bank's car loan is $407.67
(b) To find the monthly payment for the savings and loan association's car loan, we can use the same above formula:
where PV is still $21,000, PMT is the monthly payment, r is still 0.065, n is still 12, but t is now 7 years x 12 months/year = 84 payments.
putting the given values,
[tex]21000 = PMT * \frac{1 - (1 + \frac{0.065}{12})^{(-12*7)}}{\frac{0.065}{12} }[/tex]
Solving for PMT, we get:
PMT = $315.99
Therefore, the monthly payment for the savings and loan association's car loan is $315.99.
(c) Bank's car loan: $407.67 x 60 = $24,460.20
Savings and loan association's car loan: $315.99 x 84 = $26,495.16
Therefore, the bank's car loan would have the lowest total amount to pay off, by: $26,495.16 - $24,460.20 = $2,034.96
Therefore, the total amount paid would be $2,035 less for the bank's car loan than for the savings and loan association's car loan.

The probability that he or she will disapprove or have no opinion on the issue is %?
The probability that an American will disapprove or have no opinion on the issue is 13%.
What is Probability?Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, where 0 indicates an impossible event and 1 indicates a certain event. Probability is used to describe random phenomena, such as the roll of a dice, the flip of a coin, the occurrence of an earthquake, or the outcome of a hand of poker. It is also used to describe the likelihood of certain events happening based on past data or current conditions.
This can be calculated by subtracting the reported approval rate of 87% from 100%. This means that 13% of Americans disapprove or have no opinion on the issue of human embryonic stem cell research.
It is important to note that this survey's data only pertains to the opinions of Americans and not to any other group of people. Therefore, the probability that any individual randomly selected from the global population will disapprove or have no opinion on the issue may be different.

Now we can easily find b by doing 0-(-3) which is 3. so the equation of the line is y=-3x+3. Also please mark this as brainliest answer if you found it helpful thanks.
Answer:
y = - 3x + 3
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, 0 ) and (x₂, y₂ ) = (2, - 3 )
m = [tex]\frac{-3-0}{2-1}[/tex] = [tex]\frac{-3}{1}[/tex] = - 3 , then
y = - 3x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (2, - 3 )
- 3 = - 3(2) + c = - 6 + c ( add 6 to both sides )
3 = c
y = - 3x + 3 ← equation of line
Kenji walks 44 feet in 10 seconds. At this rate, how many miles does Kenji walk in an hour? Show your work. (1 mile= 5,280 feet)
Answer:
44 feet in 10 seconds = 44 x 6 (since there are 60 seconds in a minute) = 264 feet per minute
264 feet per minute x 60 minutes (since there are 60 minutes in one hour) = 15,840 feet per hour
15,840 feet per hour / 5,280 feet (since there are 5,280 feet in 1 mile) = 3 miles per hour

6r2 + 31r + 18
Therefore, the expression 6r² + 31r + 18 factors completely into (3r + 2)(2r + 9).
What is factor?In mathematics, factoring is the process of finding the factors or divisors of a given number or algebraic expression. When we factor a number or expression, we find the numbers or expressions that can be multiplied together to obtain the original number or expression. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12, since these numbers can be multiplied together in different combinations to obtain 12. Factoring is an important skill in algebra, as it helps us to simplify algebraic expressions and solve equations.
Here,
To factor the quadratic expression completely, we need to find two binomials whose product is equal to the given expression. We can start by looking for two numbers whose product is 6 x 18 = 108 and whose sum is 31. After some trial and error, we find that the numbers are 6 and 18.
We can now write the expression as:
=6r² + 31r + 18
18*6=108
27*4=108
27+4=31
= 6r² + 27r + 4r + 18
= 3r(2r + 9) + 2(2r + 9)
= (3r + 2)(2r + 9)

The lateral area of a cone is 473pi cm^2. The radius is 43 cm. Find the height to the nearest tenth
The slant height of the cone is about 11 cm. Using the Pythagorean theorem, the height is approximately 41.4 cm to the nearest tenth.
Use the formula for the lateral area of a cone: L = πrs, where L is the lateral area, r is the radius of the base, and s is the slant height.
Plug in the given values: L = 473π cm² and r = 43 cm. Then solve for s
L = πrs
473π = π(43)s
s = 473/43 ≈ 11
So the slant height of the cone is approximately 11 cm.
Use the Pythagorean theorem to find the height of the cone. Let h be the height of the cone. Then the Pythagorean theorem gives
h² + s² = r²
Substituting in the values for s and r, we get
h² + 11² = 43²
Simplifying this equation, we get
h² = 43² - 11²
Evaluating the right-hand side, we get
h² = 1764
Taking the square root of both sides, we get
h ≈ 41.4
So the height of the cone is approximately 41.4 cm to the nearest tenth.

The height of point A is 0 feet. However, this is not the actual height of point A, as it is at the highest point on the Ferris Wheel, which is 185 feet as calculated previously.
How to solveThe height of point A on the Ferris Wheel can be calculated using the sine function, as it is the vertical component of the point's position. The center of the Ferris Wheel is 100 feet off the ground, and its radius is 85 feet.
Let's denote the height of point A as h_A, which is the vertical distance from the center of the Ferris Wheel to point A.
Since point A is at the 0 radian position, it is at the highest point on the Ferris Wheel. At this point, the height of point A is equal to the sum of the radius and the center's height:
h_A = radius + center's height
h_A = 85 + 100
h_A = 185 feet
So, the height of point A off the ground is 185 feet.
To estimate the value of h_A using the sine function, we can use the fact that at any given angle θ on the unit circle, the height of the point on the circle is given by the sine of that angle multiplied by the radius. In this case, since point A is at the highest point on the Ferris Wheel, we can use the sine of 0 radians (which is 0) to estimate the height of point A:
h_A = radius * sin(0)
h_A = 85 * 0
h_A = 0
So, using the sine function, we estimate that the height of point A is 0 feet. However, this is not the actual height of point A, as it is at the highest point on the Ferris Wheel, which is 185 feet as calculated previously.
