derivative of this function

Y= -7X³ -8X² +6X +3

Answers

Answer 1

Answer:
In general, the derivative of a single term Ax^(n) is A n x^(n-1) .

And the derivative of a sum of many terms is the sum of the derivatives
of the individual terms.

Using these two rules, the derivative (with respect to 'x') of the expression
in the question is . . .

Y' = -21x² - 16x + 6

In the equation x^2 + 10x + 24 = (x + a)(x + b), b is an integer. Find algebraically all possiblevalues of b.

Answers

To factor (x² +10x+24); you first have to ask yourself, what 2 numbers will multiply and give me positive 24, but add and give me positive 10? After listing your factors, (1,24)(2,12)(3,8)and (4,6); you decide that (4*6)=24 & adds to get you 10. Meaning that (x²+10x+24) factors are (x+4)(x+6).
Now algebraically, there wouldn't be any other possible value of b, 6, because if you put (-6) & (4), those numbers will multiply and give you (-24) and add & give you (-2); & that is not what you're looking for.

I hope I explained this enough for you to understand. (:

Jesse collected 42 football cards and 28 basketball cards simpfly the ratio of baseball cards to football cards in his collection

Answers

The ratio of basketball card to football cards is 2 : 3.

What is the ratio?

A ratio indicates how many times one number contains another. If a and b are to objects then ratio of a to the b is given as a : b.

Now it is given that,

Number of football cards = 42

Number of basketball cards = 28

Hence,

Ratio of basketball cards to football cards = Number of basketball cards/Number of football cards

⇒Ratio of basketball cards to football cards = 28/42

⇒Ratio of basketball cards to football cards = 2/3

⇒Ratio of basketball cards to football cards = 2:3

Therefore,The ratio of basketball card to football cards is 2 : 3.

Baseball cards : Football cards = 28 : 42

28 : 42

7 into 28 is 4 and 7 into 42 is 6

28 : 42 = 4 : 6

2 into 4 is 2 and 2 into 6 is 3

28 : 42 = 4 : 6 = 2 : 3

So the simplified ratio of baseball cards to football cards is 2 : 3.

I hope this helps.
