Find the critical numbers (x-values) of the function y equals 2 x to the power of 5 plus 5 x to the power of 4 minus 19. Enter y

Zolol [24]

Answer:

$x=0,x=-2$

Step-by-step explanation:

From the question we are told that:

$y=2x^5+5x^4-19$

Generally the equation if differentiated is mathematically given by

$y'=10x^4+20x^3-0$

Where

y'=0

$10x^4+20x^3=0$

Factorizing,We have

$x=0,x=-2$

Therefore

The critical points are

$x=0,x=-2$

If m∠DEF= (7x + 4)°, m∠DEG= (5x +1)°, m∠GEF= 23 find each measure :)

Rudiy27

Answer:

DEF = 14.5

DEG = 8.5

Step-by-step explanation:

(7x+4) + (5x+1) = 23

12x+5 = 23

x= 1.5

DEF = 14.5

DEG = 8.5

A plastic bin contains red, yellow, and green key chains. Out of 350 key chains, 10% percent are yellow. Of the remaining key ch

Ulleksa [173]

Hello there! Thank you for asking your question here at Brainly! I will be assisting you with answering this question, and will be teaching you how to handle it on your own in the future.

We have 350 total keychains, in which 10% are yellow, 3/5 are green, and x are red. We will be solving for red, but we need to subtract 10% and 3/5 from 350.

So, let's find out how much 10% of 350 is.
Since 10% is equivalent to 1/10, we can divide 350 by 10 to find how many yellow key chains there are.
350 / 10 = 35.
There are 35 yellow key chains. We can subtract this from 350 to narrow it down.
350 - 35 = 315.

Now, let's find how much 3/5 of 350 is, and subtract it from our new number (315).

Divide 350 by 5, and then multiply that quotient by 3.
350 / 5 = 70.
70 x 3 = 210.

We have 210 green key chains. Now let's subtract that from 315. This will give us the remaining key chains - which are red.
315 - 210 = 105.

There are 105 red key chains.

I hope this helps!

James and Lin got married and got new jobs. Lin earns $3100 more per year than James. Together they earn $81,980. How much does

Bumek [7]

Answer:

The earning to James per year is $ 39,440

The earning of Lin per year is $ 42,540 .

Step-by-step explanation:

Given as :

The total earning of James and Lin together = $ 81,980 per year

The earning of Lin is $ 3100 more per year than James

Let The earning of James = $ J

And The earning of Lin = $ J + $ 3100

So, According to question

The total earning of James and Lin together = $ 81,980 per year

Or, The earning of Lin + The earning of James = $ 81,980 per year

Or, $ J + $ 3100 + $ J = $ 81,980 per year

or, 2 $ J = $ 81,980 - $ 3100

Or, 2 $ J = $ 78880

∴ J = $\frac{78880}{2}$

I.e The earning to James per year = $ 39,440

And The earning of Lin per year = $ 34,440 + $ 3100 = $ 42,540

Hence, The earning to James per year is $ 39,440

And The earning of Lin per year is $ 42,540 . answer
