Jonathan started at a new job with an hourly wage of $7.50 per hour. After having a great
performance review, they increased his hourly wage to $8.25 an hour. What was the percent
increase in his hourly wage?
Answer:To calculate the percent increase in Jonathan's hourly wage, we can use the following formula:
Step-by-step explanation:
Percent Increase = ((New Value - Old Value) / Old Value) * 100
Let's plug in the values:
Old Value (hourly wage) = $7.50
New Value (hourly wage) = $8.25
Percent Increase = (($8.25 - $7.50) / $7.50) * 100
Simplifying the calculation:
Percent Increase = ($0.75 / $7.50) * 100
Percent Increase = 0.10 * 100
Percent Increase = 10%
Therefore, Jonathan's hourly wage increased by 10%.

d₁ = t d₂ t € R. Prove that a point P(P₁, P₂) is on the line Lif and only if pid₂ = P2d₁. C11 Let L be a line in R² with vector equation
To prove that a point P(P₁, P₂) is on the line defined by d₁ = t d₂, where t ∈ R, if and only if P · d₂ = P₂ · d₁. This equation represents the dot product between the point P and the direction vector of the line.
Consider a point P(P₁, P₂) on the line defined by d₁ = t d₂, where t ∈ R. We can express the position vector of P as P = P₁d₁ + P₂d₂.
To determine if P is on the line, we need to check if this vector equation satisfies the given equation P · d₂ = P₂ · d₁. Taking the dot product on both sides, we have (P₁d₁ + P₂d₂) · d₂ = P₂ · d₁.
Expanding the dot product, we get P₁(d₁ · d₂) + P₂(d₂ · d₂) = P₂(d₁ · d₂).
Since d₁ · d₂ is a scalar value, we can rearrange the equation to obtain P₁(d₁ · d₂) = P₂(d₁ · d₂) - P₂(d₂ · d₂).
If P₁(d₁ · d₂) = P₂(d₁ · d₂) - P₂(d₂ · d₂) holds true, then the point P(P₁, P₂) is on the line. Conversely, if P is on the line, then the equation P · d₂ = P₂ · d₁ will be satisfied.
In conclusion, a point P(P₁, P₂) is on the line defined by d₁ = t d₂ if and only if P · d₂ = P₂ · d₁, which represents the dot product between the point P and the direction vector of the line.

A TV with 20% VAT costs €598. 80. How much does the tv cost without vat?
The TV cost without VAT is €479.04.
To calculate the cost of the TV without VAT, we need to remove the VAT amount from the total cost.
First, let's determine the VAT amount. Given that the TV price with VAT is €598.80 and the VAT rate is 20%, we can calculate the VAT amount as follows:
VAT amount = Total cost * (VAT rate / 100)
= €598.80 * (20 / 100)
= €119.76
To find the cost of the TV without VAT, we subtract the VAT amount from the total cost:
Cost without VAT = Total cost - VAT amount
= €598.80 - €119.76
= €479.04
It's important to note that VAT is typically added to the price of goods and services, and to find the cost without VAT, we subtract the VAT amount. The VAT rate is expressed as a percentage and is applied to the total cost to determine the VAT amount. By subtracting the VAT amount from the total cost, we obtain the cost of the TV without including the VAT.

The quadratic function modeling the helght of a ball over time is symmetric about the line t = 2.5, where is lite
Is true about this situation?
A. The height of the ball is the same after 1.5 seconds and 3.5 seconds.
B. The height of the ball is the same after 1 second and 3 seconds.
с. The height of the ball is the same after 0.5 second and 5.5 seconds.
D. The height of the ball is the same after 0 seconds and 4 seconds.
Answer:
The height of the ball is the same after 1.5 seconds and 3.5 seconds. ⇒ (A)
Step-by-step explanation:
The quadratic function is represented by a parabola
The parabola is symmetric about its vertex.The average of the x-coordinates of any opposite points (points have the same y-coordinates) on the parabola is equal to the x-coordinate of its vertex point.The axis of symmetry of it passes through the x-coordinate of its vertex point.The equation of its axis of symmetry is x = h, where h is the x-coordinate of its vertex point.∵ The quadratic function modeling the height of a ball over time
∴ f(t) = at² + bt + c
→ t is the time in second, f(t) is the height of the ball after t seconds
∵ It is symmetric about the line t = 2.5
∴ The x-coordinate of its vertex is 2.5
→ That means the average of the x-coordinates of any two
opposite points belong to f(t) is 2.5
∵ The average of 1.5 and 3.5 = [tex]\frac{1.5+3.5}{2}=\frac{5}{2}=2.5[/tex]
∴ 1.5 and 3.5 have the same value of f(t)
∴ 1.5 and 3.5 have the same height
The height of the ball is the same after 1.5 seconds and 3.5 seconds.

Use the definition given below with right endpoints to express the area under the curve y = x3 from 0 to 1 as a limit. = The area A of the region S that is bounded above by the graph of a continuous function y = f(x), below by the x-axis, and on the sides by the lines x = a and x = b is the limit of the sum of the areas of approximating rectangles. n lim Rn A = n00 lim [f(x4)Ax + f(x2)4x + = + f(x,)Ax] = lim. į f(x;)Ax n00 i=1 n lim n00 i = 1 (b) Use the following formula for the sum of cubes of the first n integers to evaluate the limit in part (a). 12 13 + 23 + 33 + ..-( ) 3 = n(n + 1) 2
The given function is y = x³ and the interval on which we are finding the area is [0, 1].
Using right endpoints, the value of x that we use for each rectangle will be the right endpoint of the subinterval on which the rectangle is being constructed. We divide the interval [0, 1] into n equal subintervals of width Δx, where Δx = (b - a) / n = (1 - 0) / n = 1 / n. Thus, the ith subinterval has endpoints xᵢ₋₁ and xᵢ, where xᵢ₋₁ = (i - 1)Δx and xᵢ = iΔx.For each subinterval, we construct a rectangle with height f(xᵢ) and width Δx, whose area is given by ΔAᵢ = f(xᵢ)Δx. Using right endpoints, we have that f(xᵢ) = f(i/n). Therefore, the area of the entire region S can be approximated by the sum of the areas of these rectangles, given by
Rn = f(Δx)Δx + f(2Δx)Δx + f(3Δx)Δx + ... + f(nΔx)Δx = ∑ᵢ₌₁ⁿf(i/n)Δx.
We can express this sum in sigma notation as
Rn = Σᵢ₌₁ⁿf(i/n)Δx.To find the exact area, we take the limit of this sum as the number of rectangles approaches infinity, or equivalently, as the width of the rectangles approaches zero, which gives us
A = lim Rn = lim Σᵢ₌₁ⁿf(i/n)Δx n→∞ n→∞
By the definition given, we can write this as
A = lim Σᵢ₌₁ⁿf(xᵢ)Δx n→∞This is the area formula using right endpoints. Now, we can apply this formula to the function y = x³ over the interval [0, 1].
We need to use the formula A = lim Σᵢ₌₁ⁿf(xᵢ)Δx to find the area under the curve y = x³ from 0 to 1.
Using right endpoints, we divide the interval [0, 1] into n equal subintervals of width Δx = 1 / n. The ith subinterval has endpoints xᵢ₋₁ = (i - 1)Δx and xᵢ = iΔx. We construct a rectangle with height f(xᵢ) = f(i/n) and width Δx for each subinterval.For the function y = x³, we have f(x) = x³. Therefore, f(i/n) = (i/n)³, and the area formula becomes
A = lim Σᵢ₌₁ⁿf(i/n)Δx= lim Σᵢ₌₁ⁿ[(i/n)³](1/n)= lim Σᵢ₌₁ⁿi³/n⁴
Taking the limit as n approaches infinity gives usA = ∫₀¹ x³ dxWe can evaluate this integral using the power rule of integration to getA = [x⁴/4]₀¹ = 1/4
Therefore, the area under the curve y = x³ from 0 to 1 is 1/4
We used the definition of the area formula with right endpoints to find the area under the curve y = x³ from 0 to 1. We divided the interval [0, 1] into n equal subintervals of width Δx, and used right endpoints to construct rectangles with height f(i/n) = (i/n)³ and width Δx = 1/n. We then took the limit of the sum of these areas as the number of rectangles approached infinity to find the exact area. Applying this formula to the function y = x³ over the interval [0, 1], we found that the area is 1/4.

Point Nis on line segment MO. Given NO=6 and MO = 20. determine the length of MN
Answer:
14
Step-by-step explanation:
You are told that the line segment MO has a total length of 20.
You are also told that point N is somewhere on that line between M and O. They tell you that the distance from point N to point O is 6. So to find the distance from point N to point M, you just subtract the length of N to O from the total length of the M to O segment.
N to O = 6
<-----M---------------------------------------------------N--------------------O------------------>
M to O = 20
So if M to O = 20 and you subtract the distance of N to O (6), you will get the distance from M to N.

A triangular corner lot has a perpendicular sides of length 30 m and 40 m. Find the dimensions of the largest rectangular building that can be constructed on the lot with one side coincident with the longest side of the lot. a. 12 m x 25 m b. 15 m x 15 m c. 20 m x 15 m d. 25 m x 10 m
The dimensions of the largest rectangular building that can be constructed on the triangular corner lot, with one side coincident with the longest side of the lot, are 15 m x 15 m.
To find the dimensions of the largest rectangular building, we need to consider the given triangular corner lot. The longest side of the lot is 40 m, and the perpendicular sides are 30 m and 40 m.
Since the rectangular building's side must be coincident with the longest side of the lot, one side of the rectangle will be 40 m. Now, we need to determine the other side to maximize the area.
To maximize the area, we need to make the rectangle as square as possible. This means the other side should be equal to the shorter perpendicular side of the lot, which is 30 m.
Thus, the dimensions of the largest rectangular building that can be constructed on the lot with one side coincident with the longest side of the lot are 40 m x 30 m, which can be simplified to 15 m x 15 m.
Therefore, the correct answer is option b) 15 m x 15 m.

glen sarin is a photographer who is wondering if there is an association between the number of photographs she takes and percent cloud coverage. her record is shown in the scatterplot. how many photographs did she take when the cloud coverage was 4 percent or less?
When the cloud coverage was 4 percent or less, Glen Sarin took approximately 45 photographs.
Glen Sarin, the photographer, wonders if there is a correlation between the percentage of cloud cover and the number of photographs she captures. She maintains a record that is depicted in the scatterplot below.
When the cloud coverage was 4 percent or less, how many photographs did she take?We can observe that, as the percentage of cloud cover increases, the number of photographs taken by Glen Sarin decreases. As per the scatterplot,
This can be done by reading the point where the 4% line of cloud cover intersects with the line of best fit and drawing a line perpendicular to the x-axis to see what is the corresponding y-value (which represents the number of photographs)
This can be interpreted as follows: the scatterplot shows a negative correlation between the percentage of cloud cover and the number of photographs taken.
This indicates that as the percentage of cloud cover increases, the number of photographs taken decreases. Glen Sarin may use this information to make informed decisions about when and where to photograph.

How many spins are expected to show a multiple of 3?
1. Determine which numbers on the spinner are multiples of 3
2. Determine the probability of a spin showing a multiple of 3
3. Use the probability to find how many spins out of 80 will result in a multiple of 3
1. The multiples of 3 are 30, 60, and 90.
2. The probability is 3/8, as there are 3 multiples of 3 out of 8 total numbers on the spinner.
3. the expected number of spins showing a multiple of 3 is (3/8) * 80 = 30.
To determine how many spins are expected to show a multiple of 3, we need to follow these steps:
1. Determine which numbers on the spinner are multiples of 3:
The numbers on the spinner are consecutive multiples of 10, beginning with 20. To find the multiples of 3, we need to look for numbers that are divisible by 3. Starting from 20, we have 20, 30, 40, 50, 60, 70, 80, and 90. Out of these numbers, the multiples of 3 are 30, 60, and 90.
2. Determine the probability of a spin showing a multiple of 3:
Since the spinner has 8 equally sized regions, the probability of spinning a multiple of 3 is the number of favorable outcomes (multiples of 3) divided by the total number of possible outcomes. In this case, the probability is 3/8, as there are 3 multiples of 3 out of 8 total numbers on the spinner.
Use the probability to find how many spins out of 80 will result in a multiple of 3:
3. To find the expected number of spins that will result in a multiple of 3, we multiply the probability by the total number of spins. Therefore, the expected number of spins showing a multiple of 3 is (3/8) * 80 = 30.
In conclusion, based on the given information, we can expect around 30 out of the 80 spins to show a multiple of 3 on the spinner.
