x/2 -5 = -3
Answers: A.4 B.1 C.-4 D.-16

Answer: The distance between the points (3, 4) and (0, 0) is 5.

Step-by-step explanation: The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. This theorem can be used to find the distance between two points in a coordinate system.

To find the distance between two points in a coordinate system, you can use the following steps:

Identify the coordinates of the two points.

Calculate the difference between the x-coordinates and the y-coordinates of the two points.

Use the Pythagorean Theorem to find the distance between the two points.

For example, to find the distance between the points (3, 4) and (0, 0), you would do the following:

Identify the coordinates of the two points: (3, 4) and (0, 0).

Calculate the difference between the x-coordinates and the y-coordinates of the two points: 3 - 0 = 3 for the x-coordinates and 4 - 0 = 4 for the y-coordinates.

Use the Pythagorean Theorem to find the distance between the two points: the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides, so the distance between the points is equal to the square root of 3^2 + 4^2 = 9 + 16 = 25 = 5.

Therefore, the distance between the points (3, 4) and (0, 0) is 5.

Ashley's hair grew at a rate of approximately 0.545 inches per month.

What is the rate of change?

Rate of change problems can generally be approached using the formula R = D/T, or rate of change equals the distance traveled divided by the time it takes to do so.

To find the rate at which Ashley's hair grew per month, we need to divide the total amount of hair growth by the number of months.

First, let's convert the units to a common denominator. 1 and 1/2 inches is the same as 3/2 inches, and 2 and 3/4 months is the same as 11/4 months.

Now we can divide the total amount of hair growth (3/2 inches) by the number of months (11/4 months) to get the rate at which Ashley's hair grew per month:

(3/2 inches) / (11/4 months) = (3/2) * (4/11) inches/month

= 6/11 inches/month

= approximately 0.545 inches/month

Therefore, Ashley's hair grew at a rate of approximately 0.545 inches per month.

Answer:

f(x) = x^3 - 7x + 1

Step-by-step explanation:

ƒ”(x)=6x ==> ƒ”(x)=6 * (x^1)

f'(x)=6/(1+1) * x^(1+1) + C  ==> C is a constant that doesn't affect the derivative

f'(x)=6/2 * x^2 + C ==> simplify the first derivative

f'(x)=3 * x^2 + C ==> f'(x)=3(x^2) + C

f'(-3)=3((-3)^2) + C  ==> plug in -3 into the derivative equation

f'(-3)=3(9) + C ==> simplify

20=3(9) + C  ==> plug in 20 for f'(-3)

20=27+C

20-27=27-27+C ==> solve for C

C=-7

f'(x)=3(x^2) + (-7)  ==> plug in -7 for C

f'(x)=3(x^2) - 7  ==> simplify

f(x) = 3/(2+1) * x^(2+1) - 7x + C

f(x) = 3/3 * x^3 - 7x + C

f(x) = x^3 - 7x + C

f(-3) = (-3)^3 - 7(-3) + C ==> plug in -3 into f(x)

f(-3) = -27 - (-21) + C

f(-3) = -27 + 21 + C ==> simplify

f(-3) = -6 + C

-5 = -6 + C  ==> plug in -5 for f(-3)

-5 + 6 = -6 + 6 + C ==> solve for C

C = 1 ==> simplify

f(x) = x^3 - 7x + 1

m<A = 112.5

m<B = 67.5

m<C = 67.5

m<D = 112.5

Consider the provided information.

The sum of all interior angle of a polygon is: (n-2)*180

Substitute n = 8.

(8-2)*180 = 1080

Thus, the measure of each angle is:

∠B and ∠C are congruent and their sum is 135°

∠B+∠C=135°

∠B=67.5°

Hence, the m angle B and m angle C is 67.5°.

The sum of all angles of a quadrilateral is 360°.

∠A+∠D+∠B+∠C=360°

∠A+∠D=360°-135°

∠A+∠D=225°

∠A and ∠D are congruent and their sum is 225°

∠A+∠D=225°

∠A=∠D=112.5°

Hence, the m angle A and m angle D is 112.5°.

Step-by-step explanation:

5x + 9y = 10

4x -3y = 8  If I multiple this second equation all the way through by 3, then the y's would cancel out when I add the equations together.

12x -9y = 24  multiplied the second equation through by 3

5x + 9y = 10  Add the 2 equations together

17x         = 34  Divide both sides by 14

x = 2

Plug 2 in for x for either of the two original equations and solve for y

5x + 9y = 10

5(2) + 9y = 10

10 + 9y = 10  Subtract 10 from both sides

9y = 0  Divide both sides by 0

y = 0

What is multiplication of matrices?

The product of two matrices A and B is defined if the number of columns of A is equal to the number of rows of B. The first matrix must have the same number of columns as the second matrix has rows. The number of rows of the resulting matrix equals the number of rows of the first matrix, and the number of columns of the resulting matrix equals the number of columns of the second matrix

Given data ,

Applying the Pythagorean theorem, the missing side of each of the right triangle are:

i. c = 15.8 m

ii. s = 24.1 cm

iii. a = 12.8 feet

iv. t = 4.6 inches

Pythagorean theorem is one that can be used to determine the third unknown side of a right angled triangle. It is given by:

/Hyp/^2 = /Adj/^2 + /Opp/^2

The missing side of each of the right triangle can be determined as:

1. Let the value of unknown hypotenuse side by represented by c, so that:

/Hyp/^2 = /Adj/^2 + /Opp/^2

c^2  = /13/^2 + /9/^2

             = 169 + 81

             = 250

c = [tex]\sqrt{250}[/tex]

  = 15.8

c = 15.8 m

2. Let the value of unknown hypotenuse side be represented by s, so that;

/Hyp/^2 = /Adj/^2 + /Opp/^2

 s^2 = /16/^2 + /18/^2

        = 256 + 324

        = 580

s = [tex]\sqrt{580}[/tex]

  = 24.1

s = 24.1 cm

3. Let the value of unknown adjacent side be represented by a,

/Hyp/^2 = /Adj/^2 + /Opp/^2

19^2 = a^2 + /14/^2

361 = a^2 + 196

a^2 = 361 - 196

      = 165

a = [tex]\sqrt{165}[/tex]

  = 12.8

a = 12.8 ft

4. Let the unknown adjacent side be represented by a,

/Hyp/^2 = /Adj/^2 + /Opp/^2

/11/^2 = t^2 + /10/^2

121 = t^2 + 100

t^2 = 121 - 100
