divide both sides
n=15/(-5)
n=-3

Using L Hospital's rule, evaluate :
lim
x →0(x² – Sin²x)/x^2
Answer:
0
Step-by-step explanation:
L Hospital's rule states that as long as u have the form
of infinity / infinity or 0/0 in general you can take its derivative to find the limit.
In this case as X tends to 0, the numerator tends to 0
Denominator will also tends to 0.
We have the 0 / 0 form, which means we can take the derivative for its numerator and denominator which gives
(2x - 2SinxCosx) / 2x | lim x -> 0
= (2x - Sin2x) / 2x | lim x -> 0
Based on this equation, as x tends to 0
both numerator and denominator tends to 0.
So we take its second derivative,
(2 - 2Cos2x) / 2
Now as x -> 0,
we will get (2 - 2)/2 = 0
is -1 equivalent to -3 - (-12)
Answer:
no
Step-by-step explanation:
-1 - (-12)
the two negative signs before the 12 cancel out so it ends up being
-1+12
-1+12=11
11 and -1 are not equal to each other
Answer:
No
Step-by-step explanation:
-3-(-12)=-3+12
-3+12=9

Caroline can ride her bike 5 miles in 25 minutes. At this rate, how long would it take her to bike 8 miles?
Answer:
40 min.
Step-by-step explanation:
5/25=1/5
1/5=0.2
8/0.2=40
Answer:
40 mins
Step-by-step explanation:
do 25 divided by 5 and you get 5, which means she can ride one mile in 5 mins, so then multiply 5 and 8 and you get the product of 40.

What should be placed in the box to make the equation true?
Answer:
2x^4
Step-by-step explanation:
When multiplying variables with exponents multiply the coefficients (the number before the variable) and add the exponents.
SO to solve you have to find a number that when multiplied by 32 equals 64 and a number when added to 8 gives you 12.
2*32=64
8+4=12
So the answer is 2x^4

5/6 minus (- 3/4)
HELP PLS
Answer:
In order to solve this problem, you have to find the lowest common denominator. Take multiples of both 6 and 4 and see which is the lowest you have in common.
4: 4, 8, 12, 16, 20
6: 6, 12, 18, 24
So 12 is the lowest common multiple....
5/6 x ?/? = ?/12 (you have to multiply the numerator and the denominator by the same number)
3/4 x ?/? = ?/12 (you have to multiply the numerator and the denominator by the same number)
When the denominators are the same, you can subtract the numerators. The denominator will stay 12!

Kim bought her Supreme shoes for $52 on eBay. She marks up the shoes to resell on GOAT for 120% of the price.
a) What is the amount of markup? $
b) What is the price of the shoes after markup? $
Answer:
a) $10.4
b) $62.4
Step-by-step explanation:
a) What is the amount of markup? $
$52 - 100%
$X - 120%
100X = 52*120
100X = 6240
X = 6240/100
X = $62.4
62.4-52=
$10.4
b) What is the price of the shoes after markup? $
$62.4

What is the volume, in cubic centimeters, of a cube with an edge length of 15
centimeters?
Answer:
3375
Step-by-step explanation:
The formula for volume is
volume = length x height x width
or in simpler terms (only works for cubes i think)
v = a^3
so we know that the side is 15cm long, so we substitute that back into the equation, so,
3375 = 15 x 15 x 15
or
3375 = 15^3
I hope that this helps you out :)

Which equation could be solved using this application of the quadratic formula? x = (- 3 plus/minus sqrt(3 ^ 2 - 4(1) * (24)))/(2(1)) A. x ^ 2 + 6x + 24 = 3x B 3x ^ 2 + 3x + 24 = 3 C. x ^ 2 + 3x - 24 = 3 D x ^ 2 + 3x + 24 = 3
Answer:
[tex]x^2 + 3x + 24 = 0[/tex]
Step-by-step explanation:
Given
[tex]x = \frac{-3\±\sqrt{3^2 - 4*1*24}}{2*1}[/tex]
Required
Select equation with the above solution
The solution is represented as:
[tex]x = \frac{-b\±\sqrt{b^2 - 4ac}}{2a}[/tex]
By comparison:
[tex]b= 3[/tex] [tex]a = 1[/tex] [tex]c = 24[/tex]
So, the equation is:
[tex]ax^2 + bx + c = 0[/tex]
[tex]x^2 + 3x + 24 = 0[/tex]
the difference of 4 and 5 times h
Answer:

difference = minus sign
and 5 times h
Answer:
Step-by-step explanation:
There are two answers to this making the question slightly ambiguous.
1) 4 - 5*h
2) (4 - 5)*h
It is impossible to tell which answer is the correct one. However, if I had to guess, I would say it is 4-5*h
