Answer:
The third choice.
(480 - 400) / 400 * 100.
Step-by-step explanation:
(480 - 400) / 400 * 100
= 80/400 * 100
= 1/5 * 100
= 20%.
The percentage increase method will be { [ 480 - 400 ] / 400 } x 100. The correct option is C.
What is the percentage?The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
The rent of an apartment is increased from $400 to $480.
The percentage change will be calculated as:-
Subtract $400 from $480 and you will get 80. Then divide 800 by 400 (because 100% = total) and you will get which means 20 %. Her hourly wage increased by 18%.
Percentage change = ( 480 - 400 ) / 400
Percentage change = 80 / 400
Percentage change = 0.2 x 100 = 20 %
Therefore, the percentage increase method will be { [ 480 - 400 ] / 400 } x 100. The correct option is C.

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

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.

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

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.
