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.

Find the axis of symmetry for the quadratic equation
Answer:
x=2
Step-by-step explanation:
To find the axis of the simmetry of parabola ( the curve of the quadratic function) we have to find the x of the top point of the parabola.
The x= -12/-(2*3)= 2
So the axis of the symmetry is the line x=2

Step-by-step explanation:
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
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.

Marco’s football team gained 13 yards on their first play, but lost 7 yards on the second. How many yards did they gain between the two plays?
Answer:
6 yards were gained between the two plays.
Step-by-step explanation:
13 minus 7 is 6.
Losing a value is decreasing, so you would use a negative sign.
Subtract the partial value lost from the total.
You get 6.
Answer:
6 yards. Marco and his football to got 6 yards.
Rachel runs 3.2 miles each weekday and 1.5 miles each day of the weekend. How many miles will she have run in 6 weeks?
Rachel will have ran 114 miles in six weeks.
There's five weekdays in a week: (3.2 x 5) = 16 miles
There's two days in a weekend: (1.5 x 2) = 3 miles
16 [weekday] + 3 [weekend] = 19 miles [7-day week]
(19 x 6) = 114 miles

Find the difference: 3/10 - 1/6
Answer:
2/15
Step-by-step explanation:
10 = 2 * 5
6 = 2 * 3
LCM of 10 , 6 = 2 * 3 * 5 = 30
[tex]\frac{3}{10}-\frac{1}{6}=\frac{3*3}{10*3} - \frac{1*5}{6*5}[/tex]
[tex]= \frac{9}{30} - \frac{5}{30}\\\\=\frac{9-5}{30}\\\\=\frac{4}{30}\\\\=\frac{2}{15}[/tex]

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?
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.

Helppp meeeeeee asappppppp
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
