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.

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

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]

A batsman scored the following number of runs in six innings:
35, 30, 45, 65, 44, 21. Calculate the mean runs scored by him in
(a) 39
(b) 38
(c) 37
(d) 40
Answer:
D
Step-by-step explanation:
The mean or average is calculated by summing each element and then dividing by the number of elements.
We have: 35, 30, 45, 65, 44, and 21.
There are six elements in total.
We find the sum by adding. Hence:
[tex]35+30+45+65+44+21=240[/tex]
We will now divide by 6, the number of elements:
[tex]240/6=40[/tex]
Therefore, the mean runs scored by the batsman is 40.
Hence, our answer is D.

Find two real numbers that have a sum of 8 and a product of 13
Answer:
The two numbers are 5.73 and 2,27
Step-by-step explanation:
Let the two numbers be x and y
[tex]x + y = 8[/tex]
[tex]xy = 13[/tex]
Make x the subject in the first equation
[tex]x = 8 - y[/tex]
Substitute 8 - y for x in the second equation
[tex](8-y)*y = 13[/tex]
Open brackets
[tex]8y - y^2 = 13[/tex]
Equate to 0
[tex]y^2 - 8y + 13 = 0[/tex]
Solve using quadratic formula
[tex]y = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]
Where
[tex]a = 1[/tex] [tex]b = -8[/tex] [tex]c = 13[/tex]
So:
[tex]y = \frac{-(-8) \± \sqrt{(-8)^2 - 4*1*13}}{2*1}[/tex]
[tex]y = \frac{8 \± \sqrt{64 -52}}{2}[/tex]
[tex]y = \frac{8 \± \sqrt{12}}{2}[/tex]
[tex]y = \frac{8 \± 3.46}{2}[/tex]
Split
[tex]y = \frac{8 + 3.46}{2}[/tex] or [tex]y = \frac{8 - 3.46}{2}[/tex]
[tex]y = \frac{11.46}{2}[/tex] or [tex]y = \frac{4.54}{2}[/tex]
[tex]y = 5.73[/tex] or [tex]y = 2.27[/tex]
Recall that
[tex]x = 8 - y[/tex]
When [tex]y = 5.73[/tex]
[tex]x = 8 - 5.73[/tex]
[tex]x = 2.27[/tex]
When [tex]y = 2.27[/tex]
[tex]x = 5.73[/tex]
Hence, the two numbers are 5.73 and 2,27

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.

Is 9, 5, 12, 11 solutions to 2w > 18?
All solutions are larger than 9
=========================================
Explanation:
Divide both sides by 2 and we get
2w > 18
2w/2 > 18/2 .... dividing both sides by 2
w > 9
Any number larger than 9 can replace w, and we'll get a true statement.
For instance, if we tried w = 12, then,
2w > 18
2*12 > 18
24 > 18
Which is true since 24 is indeed larger than 18.
On the flip side, if we tried w = 5, then,
2w > 18
2*5 > 18
10 > 18
which is not true because 10 is actually smaller than 18.
-------------------------
So again, the inequality 2w > 18 solves to w > 9
This shows all solutions are larger than 9.
If we can only pick values from the set {9,5,12,11}, then the solutions are 11 and 12 since they are larger than 9.

Answer:
Y = 20
Step-by-step explanation:
