John has earned a 77, 76, and 84 on his first three projects of the semester. If he hopes to have an B quiz average (80 or above), what is the lowest score John can make on his fourth and final project?

Answers

Answer 1

Step-by-step explanation:

John has earned a 77, 76, and 84 on his first three projects of the semester.

He hopes to have an B quiz average (80 or above).

We need to find the lowest score John can make on his fourth and final project. Let the score is x.

Average = sum of numbers/total numbers

[tex]80=\dfrac{77+76+84+x}{4}\\\\320=237+x\\\\x=83[/tex]

So, he must score 83 or more on his fourth project so as to make average 80 re above.

Determine the singular points of the given differential equation. Classify each singular point as regular or irregular. (Enter your answers as a comma-separated list. Include both real and complex singular points. If there are no singular points in a certain category, enter NONE.)(x2 − 4)2y'' + (x + 2)y' + 7y = 0

Answers

Answer:

Step-by-step explanation:

Given that:

The differential equation; [tex](x^2-4)^2y'' + (x + 2)y' + 7y = 0[/tex]

The above equation can be better expressed as:

[tex]y'' + \dfrac{(x+2)}{(x^2-4)^2} \ y'+ \dfrac{7}{(x^2- 4)^2} \ y=0[/tex]

The pattern of the normalized differential equation can be represented as:

y'' + p(x)y' + q(x) y = 0

This implies that:

[tex]p(x) = \dfrac{(x+2)}{(x^2-4)^2} \[/tex]

[tex]p(x) = \dfrac{(x+2)}{(x+2)^2 (x-2)^2} \[/tex]

[tex]p(x) = \dfrac{1}{(x+2)(x-2)^2}[/tex]

Also;

[tex]q(x) = \dfrac{7}{(x^2-4)^2}[/tex]

[tex]q(x) = \dfrac{7}{(x+2)^2(x-2)^2}[/tex]

From p(x) and q(x); we will realize that the zeroes of (x+2)(x-2)² = ±2

When x = - 2

[tex]\lim \limits_{x \to-2} (x+ 2) p(x) = \lim \limits_{x \to2} (x+ 2) \dfrac{1}{(x+2)(x-2)^2}[/tex]

[tex]\implies \lim \limits_{x \to2} \dfrac{1}{(x-2)^2}[/tex]

[tex]\implies \dfrac{1}{16}[/tex]

[tex]\lim \limits_{x \to-2} (x+ 2)^2 q(x) = \lim \limits_{x \to2} (x+ 2)^2 \dfrac{7}{(x+2)^2(x-2)^2}[/tex]

[tex]\implies \lim \limits_{x \to2} \dfrac{7}{(x-2)^2}[/tex]

[tex]\implies \dfrac{7}{16}[/tex]

Hence, one (1) of them is non-analytical at x = 2.

Thus, x = 2 is an irregular singular point.

I need help finding the equations of the line in slope intercept form

Answers

The equation would be y=2x+2.

Slope intercept form is written as y=mx+b, where m is the slope and b is the y intercept.

To find the slope, find the rise (vertical) over the run (horizontal). To get from one point to another, the line goes up by two and across by one. The slope would be 2/1 which simplifies to 2.

To find the intercept, find where the line crosses the y intercept (vertical axis). It crosses at 2.

Riddle - You enter a room. 2 dogs, 4 horses 1 giraffe and a duck are lying on the bed. 3 chickens are flying over two chairs. How many legs are on the ground?

Answers

Answer:

Trick question, either 8 legs because of the two chairs or none.

Step-by-step explanation:

The dogs and everything aren't on the ground. I think the anwser is either 8 or none.

Answer:

The number of legs on the ground are 10.

Step-by-step explanation:

Given information:

2 dogs , 4 horses and 1 giraffe and a duck are laying on the bed.

3 chickens are flying over two chairs .

Now, in the riddle the specific type of leg is not mentioned but the information is given about the bed and chair.

So, one need to consider the legs of bed and chair too, also the person entering in the room is on the ground so the legs of the person will also be counted.

Hence, total number of legs on the ground will be:

legs of (1 bed + 2 chairs + 1 person)

Hence

Number of legs (N) = 4+8+2

N=10

Hence, the number of legs on the ground are 10.

Answer:

9.2

Step-by-step explanation:

So the 14 can be divided equally on both sides by the fact that the line cutting it at right angle bisects it.

Thus having 6 and 7 as the two shorter sides of a right angled triangle will help us get the radius( hypotenuse in this case) using the square root of the sum of the squares of both six and 7, the Pythagoras theory.

this leads to 9.2 as our answer
