Find the derivative of y=x²+3x

Scorpion4ik [409]

Answer:

$\frac{dy}{dx}$ = 2x + 3

Step-by-step explanation:

Differentiate each term using the power rule

$\frac{d}{dx}$ (a $x^{n}$ ) = na $x^{n-1}$

y = x² + 3x

$\frac{dy}{dx}$ = 2 $x^{(2-1)}$ + 3 $x^{(1-1)}$

= 2x + 3 $x^{0}$

= 2x + 3

A horizontal line has points J, K, L. A line extends from point K up and to the right to point M. Angle J K M is (10 y + 6) degr

Temka [501]

Answer:

The found values are:

y = 10

<JKM = 106°

<MKL = 74°

Step-by-step explanation:

(See the diagram attached)

As JKL is a straight horizontal line, angle measure from JK to KL is 180°.

We can see in the diagram that line KM is dividing this angle of 180° into 2 unequal parts.

Which means that the sum of <JKM and <MKL is equals to 180°.

Mathematically, it can be written as:

Substitute the values of both angle to solve the equation:

$(10y+6)+(8y-6) = 180\\18y=180\\y=\frac{180}{18}\\y=10$

Put in the formulas of both angle to find their values:

<JKM = 10y + 6

<JKM = 10(10)+6

<JKM = 106°

<MKL = 8y - 6

<MKL = 8(10)-6

<MKL = 74°

The number 4 is the smallest positive integer that has exactly three factors: 1, 2, and 4. If k is the next-highest integer that

saul85 [17]

To solve this problem, we must do a method of trial and error to find for the next highest integer with exactly three factors. We know that the value of k must be greater than 4, therefore by using trial and error to find for the correct answer:

Factors of 5:1, 5

Factors of 6:1, 2, 3, 6

Factors of 7:1, 7

Factors of 8:1, 2, 4, 8

Factors of 9:1, 3, 9

Therefore we stop at 9 since this is already our answer. It has exactly three factors.

The sum of the factors is:

sum of factors = 1 + 3 + 9

sum of factors = 13

I need help with my math!!!!!!!

olga_2 [115]

Answer:

2 $\sqrt{6}$

Step-by-step explanation:

Area of a square = $s^{2}$ (s is a side length)

24 = $s^{2}$

$\sqrt{24}$ = $\sqrt{s^{2} }$

$\sqrt{24}$ = s

$\sqrt{(4)(6) }$ = s

2 $\sqrt{6}$ = s
