The slope of the line whose equation is y - 4 = (x - 2) is,
⇒ m = 1
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Equation of line is,
⇒ y - 4 = x - 2
Now, We can simplify for slope as;
⇒ y - 4 = x - 2
⇒ y = x + 2
⇒ dy/dx = 1
⇒ m = 1
Thus, The slope of the line whose equation is y - 4 = (x - 2) is,
⇒ m = 1

The average age of 40 students of a class is 15 years. An 18 year-old student left the class and a new student was admitted. As a result the average age fell to 14.885 years. Find the age of the new student.
Answer:
Answer:age of new student is 13.4 years
Step-by-step explanation:
SUM of ages all 40 students =average age times 40
=15*40=600
after leaving 18 years old student
SUM of ages of 39 students will be 600-18=582
after adding new student with age x
SUM of ages of 40 students will become 582+x
and the average would be (582+x)/40
which is given as 14.885
so we get equation
(582+x)/40=14.885
582+x=14.885*40=595.4
x=595.4-582
x= 13.4
age of new student is 13.4 years

A man is lying on the beach, flying a kite. He holds the end of the kite string at ground level and estimates the angle of elevation of the kite to be 55°. If the string is 350 ft long, how high is the kite above the ground? (Round your answer to the nearest foot.)
The kite is approximately 345 feet above the ground.
The height of the kite above the ground is 287 ft
The length of the string, the height of the kite (h) above ground and the perpendicular distance from the end of the kite string to the man forms a right angled triangle.
Trigonometric shows the relationship between the lengths and angles of a right angled triangle.
Therefore using trigonometric ratios:
sin(55) = h / 350
h = 287 ft
Therefore the height of the kite above the ground is 287 ft.

A turkey costs $1.05 per pound. There are going to be fifteen people at Thanksgiving dinner. Plan for each person to eat two, 3/8 pound servings of turkey.
How many pounds of turkey will you need to buy?
Answer:
I will need to buy 22.5 pounds of turkey and pay $23.63
Step-by-step explanation:
Proportions
Each person is planned to eat 2 x 3/8 pound servings of turkey for thanksgiving dinner. This means each person will eat
[tex]2\cdot\frac{3}{4}=\frac{3}{2}[/tex]
pounds of turkey.
There are going to be 15 people at the dinner, thus the total turkey needed is:
[tex]15\cdot\frac{3}{2}=22.5~pounds[/tex]
The turkey costs $1.05 per pound, thus the total cost is
22.5*$1.05 = $23.63
I will need to buy 22.5 pounds of turkey and pay $23.63

Water flows through a pipe at a rate of 2 fluid ounces per second. Express this rate of flow in quarts per minute.
Answer:
Step-by-step explanation:
3.75
Water flows through a pipe at a rate of 3.75 fluid quarts per minute.
What is multiplication?Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.
Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.
Given:
Water flows through a pipe at a rate of 2 fluid ounces per second.
2 ounces = 0.0625 quarts
And 1 second = 0.0166667 minutes
So, water flows through a pipe at a rate of 0.0625 quarts per 0.0166667 minutes.
Water flows through a pipe at a rate of 3.75 fluid quarts per minute.
Therefore, the rate is 3.75 fluid quarts per minute.

You are dealt one card from a standard 52-card deck. Find the probability of being dealt a red card
Answer:
It’s a 50% chance
Step-by-step explanation:
The probability of being dealt a red card is 1/2 or 50% if you are dealt one card from a standard 52-card deck.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
It is given that:
You are dealt one card from a standard 52-card deck.
Total number of red cards = 26
Total number of outcomes = 52
The probability of being dealt a red card = 26/52
The probability of being dealt a red card = 1/2
Or
The probability of being dealt a red card = 0.5 or 50%
Thus, the probability of being dealt a red card is 1/2 or 50% if you are dealt one card from a standard 52-card deck.

The total amount y (in dollars) in your savings account after buying x video games is represented by y= 90-10x. You have $40 in your account after buying video games. How many video games did you buy?
5 video games bought.
Explanation:
Step one) identify all variables.
> y = money in bank acc AFTER buying (x) video games.
Step two) y = $40
Step three) substitute
> 40 = 90 - 10x.
Step Four) solve for x
> subtract 90 both sides.
-50 = -10x
DIVIDE by -10 on both sides ( to isolated x)
This equals 5 = x
x is number of video games bought meaning >> 5 video games bought

The auxiliary equation for the given differential equation has complex roots. Find a general solution.
y''-4y' +7y =0
Answer:
y = Ae^2xcos√3 x + Be^2xsin√3 x
Step-by-step explanation:
Given the differential equation
y''-4y' +7y =0
Let my = y' and m²y =y''
The auxiliary equation is expressed as;
m²y - 4my +7y = 0
(m²-4m+7)y =0
Divide through by y;
m²-4m+7= 0
Factorize the auxiliary equation
m = 4±√16-4(7)/2
m = 4±√-12/2
m = 4±2√3 i/2
m = 2+√3i
From the complex number a = 2(real part)
b = √3 (imaginary part)
Substitute into the general solution
y = Ae^axcosbx + Be^axsinbx
y = Ae^2xcos√3 x + Be^2xsin√3 x
