Differentiate the following functions y=4x^3-2x^2+5x^-3.7-6

Katarina [22]

I don't think you copied it correctly, but I'll assume that you did.

y = 4x³ - 2x² + 5('x' to the -3.7 power) - 6

"y-prime" (the first derivative) = 12x² - 4x - 18.5('x' to the -4.7 power)

If your monthly income is $300 and you spend $50 on clothes, what percent of your monthly budget is spent on clothing

nata0808 [166]

Here is the answer to the problem above. So, if the monthly income is $300 and $50 was spent on clothing, we will find the percentage of $50 from $300 by dividing 50 by 300 then multiply the quotient by 100. So the answer is 16.67%. So the answer is 16.67%. Hope this answers your question.

Three sets have 5, 10, 15 elements, respectively. How many elements can their union and intersection have?

Degger [83]

Answer:

$Union = 15$

Step-by-step explanation:

Given

$n(A) = 5; n(B) = 10; n(C) = 15$

Solving (a): Possible union elements

This is the represented by element with the largest number of the sets

i.e.

$Union = 15$

Solving (b): Possible intersection elements

This is the represented by element with the least number of the sets

i.e.

$Intersection = 5$

Find the exact value of csc ø, if cos ø= 1/9; 180° less ø less than 270°

Iteru [2.4K]

Answer:

The answer to your question is: the first option - 9/ $\sqrt{80}$

Step-by-step explanation:

Process

cosФ = adjacent side / hypotenuse

-1/9 = adjacent side / hypotenuse

adjacent side = -1 hypotenuse = 9

c² = a² + b²

b² = c² - a²

b² = 81 - 1

b = $\sqrt{80} \\$ b = opposite side

But b is negative because we are in the third quadrant.

b = - $\sqrt{80}$

Finally csc Ф = hypotenuse / opposite side

csc Ф = - 9 / $\sqrt{80}$
