Given:

The function is

[tex]f(x)=x^2+3[/tex]

To find:

The slope of the tangent line at x = 11.

Solution:

The slope of the tangent is the value of f'(x) at x=11.

We have,

[tex]f(x)=x^2+3[/tex]

Differentiate with respect to x.

[tex]f'(x)=2x+0[/tex]              [tex]\left[\because \dfrac{d}{dx}x^n=nx^{n-1},\dfrac{d}{dx}C=0,\text{ where C is constant}\right][/tex]

[tex]f'(x)=2x[/tex]

Substitute x=11 in the above equation.

[tex]f'(11)=2(11)[/tex]

[tex]f'(11)=22[/tex]

Therefore, the slope of the tangent at x=11 is 22.

Answer:

3.2

Step-by-step explanation:

Step 1: Multiply the whole number by the denominator: 3 × 5 = 15.

Step 2: Add the product you got in Step 1 to the numerator: 15 + 1 = 16.

Step 3: Divide the sum from Step 2 by the denominator: 16 ÷ 5 = 3.2. That's it folks!

Answer:

3.2

Step-by-step explanation:

Step 1: divide numerator (1) by the denominator (5): 1 ÷ 5 = 0.2. Step 2: add this value to the the integer part: 3 + 0.2 = 3.2. So, 3 1 / 5 = 3.2.

Answer:

40%

Step-by-step explanation:

Given that :

Number of people surveyed = 2500

Number of satisfied buyers = 1000

Thus, the percentage of satisfied buyers :

(Satisfied buyers / total surveyed) * 100%

(1000 / 2500) * 100%

0.4 * 100 = 40%

40% of people surveyed were satisfied

Step-by-step explanation:

Answer:

HI = 10

Step-by-step explanation:

HI + IJ = HJ , substitute values

2x + 3x - 1 = 24 , that is

5x - 1 = 24 ( add 1 to both sides )

5x = 25 ( divide both sides by 5 )

x = 5

Thus

HI = 2x = 2 × 5 = 10

Answer:

Step-by-step explanation:

inside angle = 180 = 2x + 2x + 20 + 3x - 10 + 2x - 10

substitute the value of x = 20 into angle L, M, N, P

L = 2x + 20

L = 2(20) + 20

M = 3x - 10

M = 3(20) - 10

N = 2x - 10

N = 2(20) - 10

P = 2x

P = 2(20)

∠L + ∠M + ∠N + P = 180

60° + 50° + 30° + 40° = 180

Basically, in a function, you draw a vertical line. If that vertical line crosses the function more than once, then it is an invalid function.

Let me know if you need an example and I'll edit a picture in for you.

Answer:

A vertical line test is used to find out whether if a curve is a graph of a function or not.  If you are able to draw a vertical line, and it intersects more than one point on the curve, then it is not a function.

Step-by-step explanation:

- a midline of a trapezoid is always half of the sum of the legs.

so,

2TW = UV + SX

now plug in and solve,

2(14p + 22) = 17p + 4p + 65

28p + 44 = 21p + 65

7p = 21

p = 3

slope = 17

- use the formula for slope, and simply plug it in.

Answer:

150 degrees

Step-by-step explanation:

let x = measure of smaller angle

let 5x = measure of larger angle

larger angle plus smaller angle = 180

5x + x = 180

6x = 180

x = 30°

5(30) = 150°

Answer:

Hi...

a^2+b^2=c^2

b^2=c^2-a^2

b^2=22500-3600=18900

So...b=137/4

Answer:

The maximum revenue Luci can make selling cookies in one day is $2,000.

The price she should sell the cookies to make the maximum revenue is $1

Step-by-step explanation:

W are given the following in the question:

x= -2000 p + 4000 ................ (1)

Therefore, revenue can be obtained as follows:

Revenue = R = px = p(-2000 p + 4000) = -2000p^2 + 4000p ........... (2)

Differentiating equation (2) with respect to p and equate to 0, we have:

dR / dp = -4000p + 4000 = 0 ................. (3)

From equation (3), we solve for p as follows:

-4000p + 4000 = 0

4000 = 4000p

p = 4000 / 4000

p = 1

Therefore, this implies that the price she should sell the cookies to make the maximum revenue is $1.

Substituting p = 1 into (2), we have:

Revenue = (-2000 * 1^2) + (4000 * 1)

Revenue = -2000 + 4000

Revenue = 2000

Therefore, this implies that the maximum revenue Luci can make selling cookies in one day is $2,000.

Given:

Two points are N(-1,-11) and P(-1,-3).

To find:

The value of NP.

Solution:

Distance formula:

[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Two points are N(-1,-11) and P(-1,-3). Using distance formula, we get

[tex]D=\sqrt{(-1-(-1))^2+(-3-(-11))^2}[/tex]

[tex]D=\sqrt{(-1+1)^2+(-3+11)^2}[/tex]

[tex]D=\sqrt{(0)^2+(8)^2}[/tex]

On further simplification, we get

[tex]D=\sqrt{0+64}[/tex]

[tex]D=\sqrt{64}[/tex]

[tex]D=8[/tex]

Therefore, the value of NP is 8 units.

Answer:

angle b = 21 degrees

Step-by-step explanation:

102+57+ x =180 all triangles equal 180 degrees so set equal to 180

159+ x =180

x= 21

Answer:

The answer is 21 degrees.

Step-by-step explanation:

First of all, you should know that all the triangle sides add up to 180 degrees. Add up all the degrees, 102 + 57 + x.

102 + 57 + x = 180

159 + x = 180

x = 21
