Actually Welcome to the Concept of the derivatives.
Hence, here
y = 6x^2 -4x +17
so, dy/dx = d(6x^2-4x+17)/dx
===> hence, dy/dx = 12x -4 ( used formula d(x^n) /dx = nx^n-1 )
======> dy/dx = 12x-4

Step-by-step explanation:
Dupa ce a cheltuit in prima zi 0.4 dintro suma de bani iar in a doua zi o treime din ceea ce ia ramas. Damian mai poate cheltui 60 lei. Ce suma a avut initial?
Răspuns:
150 Lei
Explicație pas cu pas:
Fie suma inițială = x
Cheltuieli în prima zi = 0,4x
Cheltuieli pentru a doua zi = 1/3 (x - 0,4x)
Suma rămasă = 60
x = 0,4x + 1/3 (0,6x) + 60
x = 0,4x + 0,2x + 60
x = 0,6x + 60
x - 0,6x = 60
0,4x = 60
x = 60 / 0,4
x = 150 Lei

Find Lowest common factor of following questions .
56, 42, 28
Answer:
[tex]\boxed{\textsf{ The LCM of 56 , 42 , 28 is \textbf{ 168}.}}[/tex]
Step-by-step explanation:
We need to find out the LCM of 56 , 42 , 28 . So Lowest Common Multiple known as LCM is the lowest multiple which is divisible by all the numbers whose LCM is taken out . It can we done by two methods. Both of which are discussed in the attachment .
For complete solution kindly refer to the attachment .

It stands for Highest Common Factor . It is the highest numbers which divides out completely the numbers without leaving remainder of the numbers whose HCF is we are finding out .A skateboard costs $240. The sales tax on the skateboard is $12. What the percent of the sales tax?
Answer:
5%
Step-by-step explanation:
12 divided by 240 is 0.05, which is a PERCENTAGE FRACTION (as I like to call it).
This means that you can easily make this into a percentage.
Example Percentage Fractions:
A whole number, like 1 for example, is 100% or more.
The number 1 is 100%, and 2 is 200% and 4.25 is 425%
But since 12 divided by 240, in this problem, is 0.05, it is 5%.
Example are:
0.08 is 8%
0.02 is 2%
0.43 is 43%
0.79 is 79%
It's pretty simple.

are any two of the three triangles similar? if so write the appropriate similarity statement.
Answer:
Angle ABC is similar to PQR.
Postulate is Side side, side similarity
Step-by-step explanation:
In triangle ABC, AC:AB = 4/5 = 0.8
In triangle PQR, PR:PQ = 8/10 = 0.8
Looking at the triangle PQR carefully, we can deduce that QR = PR.
Thus; QR:PQ = 8/10 = 0.8.
Also,BC/AB = 4/5 = 0.8
Also, PR/RQ = 8/8 = 1 and AC/CB = 4/4 = 1
Both triangles have the same proportion of their sides and thus we can say they are similar.
Postulate used is Side, Side, Side similarity.

Step-by-step explanation:
The Johnsons are having a family reunion and they want to order T-shirts. 36 people will be
attending the reunion. There will be twice as many children as adults at the reunion. Set up a
system of equations that represents the numbers of adults and children that are attending the
reunion and solve the system to figure out how many adult and child T-shirts they need to buy.
(hint: let a=the number of adults, and c=the number of children)
Answer:
a= 12, c= 24
The Solution:
a=?, c=?, No. of people attending=36
since c is twice as many as a, a= 2a
a + 2a= 36
3a= 36
(divide both sides by 3)
3a/3=36/3
a= 12
therefore, a= 12
since c is equals to 2a,
2a= 2(12)
2a= 24
therefore, c= 24
Six friends are sharing 8 cups of lemonade. If they share the lemonade equally, how many cups will each friend get? simplify your answer to a mixed number
Answer:
Step-by-step explanation:
Divide the 8 cups between 6 people: 8/6 = 1.333
As a mixed fraction, that is 1(1/3)
As an improper fraction (that you didn't ask for but whatever), it's 4/3
Each friend gets [tex]1\frac{1}{3}[/tex] cups of lemonade.
What is Division?A division is a process of splitting a specific amount into equal parts.
Given that Six friends are sharing 8 cups of lemonade.
The friends share 8 cups lemonade equally.
We need to find the number of cup each friend will get.
To find this we have to divide eight by six.
In this questions we are splitting 8 cups among 6 friends.
Divide 8 by 6
8/6
Now divide numerator and denominator by 2
4/3
Now let us convert this to mixed fraction
[tex]1\frac{1}{3}[/tex]
Hence, each friend gets [tex]1\frac{1}{3}[/tex] cups of lemonade.
