Find the 107 the derivative of the function

Answer:

x = -5

Step-by-step explanation:

If one draws a perfect verticle line at x = -5, one will have exactly 1/2 the parabola on each side. Then is one where to fold the parabola on that line, then there would be no overhang. Hence x = -5 is the axis of symmetry.

The length and midpoint of segment PQ, where the coordinate of P is (8, -15), and Q is (13, -10) are;

The given points are;

P(8, -15) and Q(13, -10),

Part A:

The distance between the points P and Q, which may be expressed as d(P, Q), is found as follows;

d(P, Q) = √((13-8)²+(-10-(-15))²) = √(50) = 5•√2

The length of PQ is therefore;

Second part;

The midpoint of segment PQ is obtained from the midpoint formula as follows;

[tex](x_m, y_m) = \left(\frac{x_1 + x_2}{2}, (\frac{y_1 + y_2}{2} \right)[/tex]

The midpoint, [tex](x_m, y_m) [/tex] of PQ is therefore;

[tex](x_m, y_m) = \left(\frac{8+13}{2}, \frac{(-15) + (-10)}{2} \right) = \left(11.5, -12.5\right) [/tex]

The coordinates of the midpoint of segment PQ is (11.5, -12.5)

Answer:

2.5198421

Step-by-step explanation:

Answer:

The numbers are:

{-1, 0, 1, 2, 3}

Step-by-step explanation:

Note: I am assuming "between" does not include the endpoints.

Given the statement

'Four times a number, increased by one, is between negative seven and seventeen'

Let us break down the word statement into small pieces and then combine them to write it into an algebraic expression.

Let x be the number.

4 times a number = 4x

Increase by 1 = 4x+1

between negative seven and seventeen ⇒   -7 < 4x+1  < 17

Thus, the combined statement can be written in an algebraic expression.

-7 < 4x+1  < 17

solving the inequality expression

[tex]-7 < 4x+1 < 17[/tex]

Add -1 to all parts

[tex]-7+-1<4x+1+-1<17+-1[/tex]

[tex]-8<4x<16[/tex]

Divide all parts by 4

[tex]\frac{-8}{4}<\frac{4x}{4}<\frac{16}{4}[/tex]

[tex]-2<x<4[/tex]

Thus, the numbers are:

{-1, 0, 1, 2, 3}

i.e

[tex]-7<4x+1<17\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-2<x<4\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-2,\:4\right)\end{bmatrix}[/tex]

Answer:

360 tablespoons.

Answer:

x = 20/3 or x = -12/5

Step-by-step explanation:

Solve for x over the real numbers:

2 abs(x - 1) = x/2 + 8

Divide both sides by 2:

abs(x - 1) = 1/2 (x/2 + 8)

Split the equation into two possible cases:

x - 1 = 1/2 (x/2 + 8) or x - 1 = 1/2 (-x/2 - 8)

Expand out terms of the right-hand side:

x - 1 = x/4 + 4 or x - 1 = 1/2 (-x/2 - 8)

Subtract x/4 - 1 from both sides:

(3 x)/4 = 5 or x - 1 = 1/2 (-x/2 - 8)

Multiply both sides by 4/3:

x = 20/3 or x - 1 = 1/2 (-x/2 - 8)

Expand out terms of the right-hand side:

x = 20/3 or x - 1 = -x/4 - 4

Add x/4 + 1 to both sides:

x = 20/3 or (5 x)/4 = -3

Multiply both sides by 4/5:

Answer: x = 20/3 or x = -12/5

Answer:

∠EFA

Step-by-step explanation:

The diagram shows several rays starting at point F. There are 2 sets of rays that are opposite to each other ie their angles add up to 180°

These are
FD and FA
FB and FE

You can ignore the other two rays since they do not have any opposite rays and therefore do not figure in a linear relationship

Ignoring FG and FC we get the equivalent of two lines crossing each other at point F

We can eliminate any angles that contain C and G
So we can eliminate ∠BFC, ∠CFG and ∠GFD

Which leaves the last choice as the only option

So answer is ∠EFA

∠EFA is linearly paired with ∠BFD since they lie on the same straight line and the measure of sum of their angles is 180°

∠EFA also is vertically paired with ∠BFD since these angles are opposite each other

The required answers for the given questions is question are 1) x = -4,  2)  x = 6 - √15,   3) x = 3 + 3√3,   4) x = -3,  and  5)x = -9 - √21  / 5

The quadratic Equation formula is x = -b ± √(b² - 4ac) / 2a

1. x² + 7x + 12 = 0

By using the above formula

Here a = 1, b = 7, c = 12

x = -7 ± √(7² - 4*1*12) / 2*1

x = -7 ± √(49 - 48) / 2

x = -7 ± √1 / 2

x = -7 ±1 /2

x = -7+1 /2           x = -7 - 1 / 2

x = - 6 / 2            x = -8 / 2

x = -3                   x = -4

2) x²-12x+21=0

By using the above formula

Here a = 1,  b = -12, c = 21

x = -(-12) ± √((-12)² - 4*1*21) / 2*1

x = 12 ± √(144 - 84) / 2

x = 12 ± √60 / 2

x = 12 ±2√15  /2

x = 12 + 2√15 /2           x = 12 - 2√15  / 2

x = 6 + √15          x = 6 - √15

3. 18+6y-y²=0

By using the above formula

Here a = -1, b = 6, c = 18

x = -6 ± √((6² - 4*(-1)*18) / 2*(-1)

x = -6 ± √(36 + 72) / -2

x = -6 ± √108 / -2

x = -6 ± 6√3 / -2

x = -6+6√3 /-2           x = -6 - 6√3 / -2

x = 3-3√3            x = 3 + 3√3

4. 3x²+14×+15=0

By using the above formula

Here a = 3, b = 14, c = 15

x = -14 ± √((14² - 4*(3)*15) / 2*(3)

x = -14 ± √(196 - 180) / 6

x = -14 ± √16 / 6

x = -14 ± 4 / 6

x = -14 + 4 /6           x = -14 - 4  / 6

x = -10 / 6                x = -18 / 6

x = -5/3                   x = -3

5.5x²-18x+12=0 ​

By using the above formula

Here a = 5, b = -18, c = 12

x = -18 ± √((18² - 4*(5)*12) / 2*(5)

x = -18 ± √(324 - 240) / 10

x = -18 ± √84 / 10

x = -18 ± 2√21 / 10

x = -18 + 2√21 /10           x = -18 - 2√21  / 10

x = -9 + √21 / 5                x = -9 - √21  / 5

Hence, the values of the given question are 1) x = -4,  2)  x = 6 - √15,   3) x = 3 + 3√3,   4) x = -3,  and  5)x = -9 - √21  / 5

Answer:

Step 1     z(c) = 2,323

CI = (  25 ;  30,2 )

Step-by-step explanation:

Normal Distribution:

Sample size  n = 25

Sample mean   μ  = 27,6

Sample standard deviation  s = 5,69

CI = 98 %   then  α  = 1 - 0,98     α = 0,02    α/2  = 0,01

From z-table we don´t  find z (score) for 0,01   directly, we need to interpolate between z = 2,32   and z = 2,33

For   0,0099           z score   is    2,33

for    0,0102            z score   is    2,32

Δ      0,0003                                  0,01

Then   by rule of three

for Δ        0,0003                ⇒      0,01

for Δ   (0,01- 0,0102)          ⇒        x

0,0003    0,01

0,0002      x

x = 0,0067

then  z (score for 0,01)   =  2,33 - 0,0067     z(c) = 2,3233

round to three decimal places z(c) = 2,323

Step 2:

CI =   μ  ±  z(c) * s/√n    ⇒   27,6  ± (2,323 * 5,69)/5

CI =  27,6 ± 2,6436

round to one decimal place

CI = 27,6 ± 2,6

CI = (  25 ;  30,2 )
