Y= 2/5x +1
Using the first point, you find the Y-intercept (y=mx+1)
Then plug the coordinates into the equation y2-y1/x2-x1
(y=2/5x+1). Hope this helps :))
Answer:
y = \(\frac{2}{5}\) x + 1
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 = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)
with (x₁, y₁ ) = (0, 1 ) and (x₂, y₂ ) = (5, 3 )
m = \(\frac{3-1}{5-0}\) = \(\frac{2}{5}\)
The line crosses the y- axis at (0, 1 ) ⇒ c = 1
y = \(\frac{2}{5}\) x + 1 ← equation of line

Suppose the annual interest rate is 7.5% and the interest is compounded annually. How much will an investment of $1,000 be worth after 3 years?
An investment of $1,000 at an annual interest rate of 7.5%, compounded annually, will be worth $1,232.28 after 3 years.
What is value?Value is a term used to describe the worth of something, either in terms of money, or in terms of importance or usefulness. Value can be determined in terms of the amount of money something is worth, or the level of importance or usefulness it has to someone. When something has a high value, it means that it is worth a lot of money or has a high level of importance or usefulness.
The value of an investment of $1,000 after 3 years at an annual interest rate of 7.5%, compounded annually, can be calculated using the following formula:
Future Value (FV) = Present Value (PV) × (1 + r)ⁿ
Where PV is the present value of the investment ($1,000 in this case), r is the annual interest rate (7.5%) and n is the number of years (3).
Using this formula, we can calculate the future value of the investment after 3 years as follows:
FV = $1,000 × (1 + 0.075)³
FV = $1,000 × 1.23228
FV = $1,232.28
Therefore, an investment of $1,000 at an annual interest rate of 7.5%, compounded annually, will be worth $1,232.28 after 3 years.

Compare which is better the 50% one or this one. Another brand of sheets is on sale 30% off with a regular price of $18.00 per sheet. Which is a better deal, the previous example or this one? Explain.
The cost of the sheets is less for the second example, the second example is the better deal.
Consider the first example:
Here, A brand of sheets is on sale for “Buy one get one at 50% off”. If each sheet costs $18.00.
So, the value of the first sheet will be $18,
And since the other sheet is at 50% off .
That is it will be half of the original value
= 50/100 * 18
=9
Therefore, the cost of two sheets
=$18 + $9
= $27.
So, Six sheets will cost
=$27+$27+$27
= $81
Cost of six sheets will be $81
Now, consider the second example
In the second example sheets are 30% off.
So, 30% of 18
= $6.
Subtract that value from 18 and you will get $12.
So, cost of one sheet = $12.
cost of 6 sheet
= $12×6
= $72
In the first example, Six sheets costs $81, while in the second example six sheets cost $72.
Since the cost is less for the second example. So, the second example is the better deal.

Solve the given differential equation by separation of variables. dy dx = e4x 5y
The solution to the given differential equation \(\frac{dy}{dx} = e^{4x+5y}\) is , \(\frac{e^{-5y}}{-5}=\frac{e^{4x}}{4} +c\), where c is constant of integration.
For given question,
We have been given a differential equation \(\frac{dy}{dx} = e^{4x+5y}\)
We know that for any real number a, m, n,
\(a^{m + n} = a^m \times a^n\)
⇒ dy/dx = \(e^{4x}\) × \(e^{5y}\)
Separating the variables (x and its differential in one side and y and its differential in another side )
⇒ \(\frac{1}{e^{5y}}\) dy = \(e^{4x}\) dx
⇒ \(e^{-5y}\) dy = \(e^{4x}\) dx
Integrating on both the sides,
⇒ \(\int e^{-5y}\) dy = \(\int e^{4x}\) dx
We know that, \(\int e^{ax}\, dx=\frac{e^{ax}}{a} +C\)
⇒ \(\int e^{4x}\, dx=\frac{e^{4x}}{4} +C\)
and \(\int e^{-5y}\, dy=\frac{e^{-5y}}{-5} +C\)
So the solution is, \(\frac{e^{-5y}}{-5}=\frac{e^{4x}}{4} +c\), where c is constant of integration.
Therefore, the solution to the given differential equation \(\frac{dy}{dx} = e^{4x+5y}\) is , \(\frac{e^{-5y}}{-5}=\frac{e^{4x}}{4} +c\), where c is constant of integration.

Compare and contrast Theorem 7.9 and the Triangle Angle Bisector Theorem.
Theorem 7.9 states that if a line is drawn parallel to one side of a triangle, then it divides the other two sides proportionally. On the other hand, the Triangle Angle Bisector Theorem states that if a line bisects an angle of a triangle, then it divides the opposite side into segments that are proportional to the adjacent sides.
Now, let's compare and contrast these two theorems.
Both Theorem 7.9 and the Triangle Angle Bisector Theorem involve lines that intersect a triangle. However, they differ in terms of the type of line and the property they describe.
Theorem 7.9 deals with a line that is parallel to one side of the triangle, while the Triangle Angle Bisector Theorem deals with a line that bisects an angle of the triangle.
In terms of the property they describe, Theorem 7.9 states that the line divides the other two sides proportionally. In contrast, the Triangle Angle Bisector Theorem states that the line divides the opposite side into segments that are proportional to the adjacent sides.
To summarize, Theorem 7.9 deals with a line that is parallel to one side of a triangle and divides the other two sides proportionally.

In a normal distribution, what z-score cuts off the top 90% of the distribution? Z=-0.58 , Z=-1.28 ,Z=+0.58 ,Z=+1.28
IN a normal distribution, what z-score cuts off the top 90% of the distribution the z-score that cuts off the top 90% of the distribution is Z = +1.28.
In a normal distribution, the z-score represents the number of standard deviations a data point is away from the mean. The area under the normal curve can be calculated using z-scores. To find the z-score that cuts off the top 90% of the distribution, we need to find the z-score corresponding to an area of 0.90.
Using standard normal distribution tables or a calculator, we can find that the z-score associated with an area of 0.90 is approximately +1.28. This means that the value at +1.28 standard deviations above the mean marks the cutoff point for the top 90% of the distribution. Any value beyond this z-score represents the upper 10% of the distribution.
Therefore, the correct answer is Z = +1.28, as this is the z-score that cuts off the top 90% of the distribution in a normal distribution.

It is presentation day in class and your instructor is drawing names from a hat to determine the order of the presentations. If there are 15 students in the class, what is the probability that the first 2 presentations will be by Mila and Sara, in that order
The probability of Mila and Sara presenting first in that specific order can be calculated by dividing the favorable outcomes by the total number of possible outcomes. In this case, the probability is 1/105.
To determine the probability, we need to consider the total number of possible outcomes and the number of favorable outcomes. Since the order matters in this scenario, we will use the concept of permutations. There are 15 students in the class, so the total number of possible outcomes is the number of ways to arrange 15 students, which is denoted by 15!.
For the first presentation, there is only one specific student, Mila, who needs to present first. Therefore, there is 1 way to arrange the first presentation. After Mila presents, there are 14 students left, and Sara needs to present second. So there is 1 way to arrange the second presentation as well. The remaining 13 students can be arranged in 13! ways.
To calculate the probability, we divide the number of favorable outcomes (1 * 1 * 13!) by the total number of possible outcomes (15!). Thus, the probability of Mila and Sara presenting first in that specific order is 1/105.

Given expression:
(0.06) · (0.154)When multiplying decimals, multiply as if there are no decimal points:
\(\implies 6 \times 154 = 924\)
Count the number of digits after the decimal in each factor:
0.06 → 2 digits0.154 → 3 digitsTherefore, there is a total of 5 digits.
Put the same number of total digits after the decimal point in the product:
\(\implies (0.06) \cdot (0.154)=0.00924\)
-----------------------------------------------------------------------------------------------
Answer option A
\(\boxed{6 \cdot \dfrac{1}{100} \cdot 154 \cdot \dfrac{1}{1000}}\)
When dividing by multiples of 10 (e.g. 10, 100, 1000 etc.), move the decimal point to the left the same number of places as the number of zeros.
Therefore:
6 ÷ 100 = 0.06154 ÷ 1000 = 0.154\(\implies 6 \cdot \dfrac{1}{100} \cdot 154 \cdot \dfrac{1}{1000}=(0.06) \cdot (0.154)\)
Therefore, this is a valid answer option.
Answer option B
\(\boxed{6 \cdot 154 \cdot \dfrac{1}{100000}}\)
Multiply the numbers 6 and 154:
\(\implies 6 \times 154 = 924\)
Divide by 100,000 by moving the decimal point to the left 5 places (since 100,000 has 5 zeros).
\(\implies 6 \cdot 154 \cdot \dfrac{1}{100000}=0.00924\)
Therefore, this is a valid answer option.
Answer option C
\(\boxed{6 \cdot (0.1) \cdot 154 \cdot (0.01)}\)
Again, employ the technique of multiplying decimals by first multiplying the numbers 6 and 154:
\(\implies 6 \cdot 154 = 924\)
Count the number of digits after the decimal in each factor:
0.1 → 1 digit0.01 → 2 digitsTherefore, there is a total of 3 digits.
Put the same number of digits after the decimal point in the product:
\(\implies 0.924\)
Therefore, as (0.06) · (0.154) = 0.00924, this answer option does not equal the given expression.
Answer option D
\(\boxed{6 \cdot 154 \cdot (0.00001)}\)
Again, employing the technique of multiplying decimals.
As there are a total of 5 digits after the decimals:
\(\implies 6 \cdot 154 \cdot (0.00001)=0.00924\)
Therefore, this is a valid answer option.
Answer option E
\(\boxed{0.00924}\)
As we have already calculated, (0.06) · (0.154) = 0.00924.
Therefore, this is a valid answer option.

A) I only
B) II only
C) III only
D) I and II only
For the given equation which shows the relation of temperature in Celsius and Fahrenheit, the correct option is Option D.
What is meant by temperature?
Indicating the direction in which heat energy will naturally flow from a hotter body (one with a higher temperature) to a colder body(one at a lower temperature), the temperature is a measure of hotness or coldness defined in terms of any of several arbitrary scales.
The given equation is:
\(C = \frac{5}{9} (F- 32)\)
where C = temperature in Celsius
F = temperature in Fahrenheit
The above equation can be rewritten as:
C = 5/9F - 160/9
Now, this is an equation of a straight line with a formula,
y = mx + c
Comparing,
m = 5/9 which is the slope of the equation.
This means that for a temperature increase of 1 degree Fahrenheit, the equivalent increase in temperature in Celsius is 5/9.
So the option I is true.
Similarly, an increase in 1 degree Celsius of temperature is equivalent to 9/5 = 1.8 degree increase in Fahrenheit.
So option II is true.
Option III is not true as is discussed above.
Therefore for the given equation of temperature, the correct option is Option D.

Multiply the polynomial by distribution. Show your work and explain the steps you used to solve.
(a – 3)(a2 + 2a – 6)
help please
Hello,
Why "Multiply the polynomial by distribution" ?
It's s t u p i d, you compliquate the equation.
In order to find the roots of P(a)=(a-3)(a²+2a-6)=0
a²+2a-6
=(a²+2a+1)-7
=(a+1)²-7
=(a-√7)(a+√7)
P(a)=(a-3)(a-√7)(a+√7)
Roots are 3,√7 and -√7
