Increasing, as the slope is positive (1/2)
Answer:
Increasing.
Step-by-step explanation:
[tex]\boxed{\begin{minipage}{6.3 cm}\underline{Slope-intercept form of a linear equation}\\\\$y=mx+b$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $b$ is the $y$-intercept.\\\end{minipage}}[/tex]
Given linear equation:
[tex]y=\dfrac{1}{2}x+2[/tex]
Comparing the given linear equation with the slope-intercept formula, the slope of the given equation is ¹/₂.
The graph of a linear equation is increasing if its slope is positive.
(y-values increase as x-values increase).
The graph of a linear equation is decreasing if its slope is negative.
(y-values decrease as x-values increase).
Therefore, as the slope of the given linear equation is positive, its graph is increasing.

Jeremy's mother deposited $1,200 into a

was born. How much will Jeremy have in
this account after 18 years at a yearly
simple interest rate of 4.25%?
A) $51.00
C) $918.00
B) $10,380.00
D) $2,118.00
Answers
Answer: D) $2,118.00
Step-by-step explanation:
1 year = 4.25% interest rate
18 years = 76.5% interest rate
76.5% = 0.765
Take 1200 times 0.765 = $918.00
$918.00 is the interest money he will receive after 18 years. We have to add both numbers to find the total.
$1,200 + $918.00 = $2118.00

Write a system of equations and then solve by the method of your choice: substitution or elimination
Answers
There are 30 questions for 2 points and 10 questions for 4 point.
What is elimination method?
The elimination approach involves taking one variable out of the system of linear equations by utilizing addition or subtraction together with multiplication or division of the variable coefficients.
Given that, the total number of equations is 40. Total point on the paper is 100 points.
There are two types questions, one type question contains 2 points and other type question contains 4 points.
Assume that, there are x questions for 2 points and y questions for 4 points.
The total number of questions is x + y.
The total point is 2x + 4y.
Therefore,
x + y = 40 ......(i)
2x + 4y = 100 .....(ii)
Multiply 2 with equation (i)
2x + 2y = 80
2x + 4y = 100
___________
-2y = -20
Divide both sides by -2:
y = 10
Putting y = 10 in equation (i)
x + 10 = 40
x = 30

Answers
Three of the seven phases of the impulse purchase cycle. The other phases include antecedent, search, and selection.
The impulse purchase cycle is a model that describes the process of making an impulsive purchase. It is typically divided into seven phases:
Antecedent: This phase is characterized by a need or desire for something. It can be triggered by a variety of factors, such as boredom, hunger, or a sudden craving for a particular product.
Search: In this phase, the consumer begins to actively search for a product that will satisfy their need or desire. They may search online or in physical stores, and they may consider various options before deciding on a product.
Selection: In this phase, the consumer narrows down their options and selects a specific product that they want to purchase. They may consider factors such as price, quality, and convenience when making their decision.

c(x) = 5. 50x 20. 50
c(x) = 5. 50 21. 60x
c(x) = 5. 50x 21. 60
Answers
The function is: c(x) = 5.50 + 21.60x. This means that for each ticket purchased, an additional $21.60 will be added to the service fee of $5.50.
The total cost for ordering 5 tickets is $108.00. This means that each ticket costs $20.50 plus a service fee of $5.50.
Therefore, we can create a linear function that represents the total cost when x tickets are ordered. The function is: c(x) = 5.50 + 21.60x. This means that for each ticket purchased, an additional $21.60 will be added to the service fee of $5.50.
When x = 5, then c(x) = 5.50 + 21.60x = 5.50 + 21.60(5) = 108.00, which matches the given total cost.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the size of the balls be represented as = x
The number of balls = 2
So , the total size of the balls = 2x
Now , the equation will be
The weight of all the elements = 160 grams equation (1)
The weight is balanced by = 40 grams + 2x equation (2)
Now , equation (1) = equation (2)
Substituting the values in the equation , we get
160 = 2x + 40
On simplifying the equation , we get
Subtracting 40 on both sides of the equation , we get

The centroid of the region in the first quadrant bounded by the given curves is (81/170, 81/170).
In the given question, we have to find the centroid of the region in the first quadrant bounded by the given curves.
The given curves are:
y = x^8, x = y^8
We can write the curves as
y = x^8...........................(1)
y = x^{1/8}.......................(2)
Now putting the value of y from equation 1 in equation 2, we get
x^8 = x^{1/8}
Now simplifying,
x^{64} = x
x^{64}-x = 0
x(x^{63} - 1) = 0
After equating equal to zero,
x = 0, x = 1

Answers
The rate at which the radius is increasing is; 0.006 in/min
How to find the rate of increase of radius?We are given that the formula for the volume of a spherical balloon is;
V = ⁴/₃πr³
where r is the radius
The volume is increasing at the constant rate of 0.78 inches per minute. Thus;
dV/dt = 0.78
Now, differentiating with respect to t gives;
dV/dt = ⁴/₃(3πr²)(dr/dt)
At radius of 3.2 inches, we have;
0.78 = 4π * 3.2² * dr/dt
dr/dt = 0.78/(4π * 3.2²)

Answers
The resulting sampling technique is Stratified sampling.
As in the concept of statistical study, sampling methods refer to how we select members from the population to be in the study and if a sample isn't randomly selected, it will probably be biased in some way and the data may not be representative of the population.
Here we need to find the type of sampling method.
Here the Stratified random sampling involves classifying the units of the population into different strata.
And the give units in each stratum should possess similar characteristics which then allows the researcher to pick a sample from each.
Then the stratified sampling approach can be divided into proportionate stratified sampling and disproportionate stratified sampling
Therefore, these method is employed in cases where the population is heterogeneous.
So, option (b) is correct.

Given is the function, as follows -
f(x) = (x²/15 + 6x - 9x²/{3/2})
The given function is -
f(x) = (x²/15 + 6x - 9x²/{3/2})
∫f(x) = ∫(x²/15 + 6x - 9x²/{3/2}) dx
∫f(x) = ∫(x²/15)dx + ∫(6x)dx - ∫(6x²)dx
