Step-by-step explanation:

42-13=29

The general equation represented as: [tex]\mathbf{x^2 = 2py}[/tex]

The equation is given as:

[tex]\mathbf{x^2 = 64y}[/tex]

Recall that:

[tex]\mathbf{x^2 = 2py}[/tex]

Where:

[tex]\mathbf{F = (0,\frac p2)}[/tex] --- the focus

[tex]\mathbf{y = -\frac p2}[/tex] --- the directrix

Compare [tex]\mathbf{x^2 = 2py}[/tex] and [tex]\mathbf{x^2 = 64y}[/tex], we have:

[tex]\mathbf{2py = 64y}[/tex]

Divide both sides by 2y

[tex]\mathbf{p = 32}[/tex]

Recall that:

[tex]\mathbf{F = (0,\frac p2)}[/tex]  and [tex]\mathbf{y = -\frac p2}[/tex]

So, we have:

[tex]\mathbf{F = (0,\frac {32}2)}[/tex]

[tex]\mathbf{F = (0,16)}[/tex]

[tex]\mathbf{y = -\frac p2}[/tex]

[tex]\mathbf{y = -\frac{32}{2}}[/tex]

[tex]\mathbf{y = -16}[/tex]

The axis of symmetry is [tex]\mathbf{x = 0}[/tex]

Step-by-step explanation:

Answer:

Negative 5 and StartFraction 7 over 8

Step-by-step explanation:

Answer: A. Rosa is correct in using a division expression because the term ""per"" implies the quotient of the quantities before and after that word.

Step-by-step explanation:

The term ; Cost per pound can be interpreted mathematically to mean;

Cost / pound ; where per means division. In the context above ;

cost per pound = cost of 1 pound of an item ;

(Stated Cost of the item ÷ pound of the item at the stated cost)

For the question above ;

2/3 pounds of ground beef cost $4;

Cost per pound = cost of 1 pound of ground beef ;

= $4 ÷ (2/3)

= $6

Hence, 1 pound of ground beef cost $6

Answer:

Step-by-step explanation:

7) ∠1  + 30 = 180                {linear pair}

            ∠1 = 180 - 30

            ∠1 = 150

8)  ∠2 = 30    {Vertically opposite angles are congruent}

9) In ΔLMN,

∠L + ∠N + ∠M = 180   {angle sum property of triangle}

50 + 30 + ∠M = 180

       80 + ∠M = 180

                ∠M = 180 - 80

                ∠M = 100°

10) Sum of exterior angle of a triangle equals to sum of opposite interior angles.

∠B + ∠A = ∠BCD

30 +   ∠A = 80

        ∠A  = 80 - 30

      ∠A = 50

Answer:

$23,275.817

Step-by-step explanation:

To get this answer, multiply 19,000 by 1.07.

$19,000 x 1.07 = 20,330 (one year later)

$20,330 x 1.07 = $21,753.10 (two years later)

$21,753.10 x 1.07= $23,275.817 (three years later)

The answer round to cents would be $23,275.82

Answer:  Rotate z by 90° clockwise about the origin.

Step-by-step explanation:

Suppose we have the number z = a + b*i, that can be represented with the point (a, b) in a coordinate axis.

If we divide z by i, we have:

[tex]\frac{z}{i} = \frac{a + b*i}{i} = \frac{a + b*i}{i} *\frac{i}{i} = \frac{a*i - b}{-1} = b - a*i[/tex]

This point will be represented with the point (b, -a)

Then we have the transformation:

(a, b) ----> (b, -a)

This is a rotation of 90° clockwise about the origin.

Then the correct option is:

Rotate z by 90° clockwise about the origin.

Answer:

C

Step-by-step explanation:

Answer:

Step-by-step explanation:

m∠4 + m∠16 = 180° [Consecutive exterior angles]

m∠16 = m∠14 [corresponding angles]

Therefore, m∠4 + m∠14 = 180°

m∠7 + m∠11 = 180° [Consecutive interior angles]

m∠11 = m∠9 [Corresponding angles]

Therefore, m∠7 + m∠9 = 180°

In both the cases sum of the given angles is 180°.

Therefore, measure of ∠4 and ∠14 are related in the same way as the measurement of ∠9 and ∠7.

Answer:  x = 28

===================================================

Explanation:

The angles COE, EOF, and FOB combine to form angle COB

angle COB = (angleCOE)+(angleEOF)+(angleFOB)

angle COB = (3x)+(x)+(x+12)

angle COB = 5x+12

----------

Angles AOD and COB are vertical angles, so they are congruent

angle COB = angle AOD

5x+12 = 152

5x = 152-12

5x = 140

x = 140/5

x = 28

Answer:

The speed of the boat is 20 km/hr

Step-by-step explanation:

Let s be the speed of boat in still water

Let d be the distance

Upstream speed = s-4

Jane took 30 min to drive her boat upstream to water-ski at her favorite spot.

So, Distance traveled in upstream =[tex]Speed \times time =(s-4) \times \frac{30}{60}[/tex]

Downstream speed = s+4

So, Distance traveled in downstream = [tex]Speed \times time =(s+4) \times \frac{20}{60}[/tex]

So, [tex](s-4) \times \frac{30}{60}=(s+4) \times \frac{20}{60}[/tex]

30s-120=20s+80

10s=200

s=20

Hence The speed of the boat is 20 km/hr

Answer:

-7

Step-by-step explanation:

Let the number be represented with 'Y'

Half of the number will be = Y/2

The difference of half of a number and 3

= Y/2 - 3

Is equivalent to negative 5

That is,

Y/2 - 3 = -5

y/2-3/1 = -5/1

Collect like terms

y/2 = -5/1+3/2

y/2 = -7/2

Multiply both sides by 2

y/2 ×2 = -7/2×2

Y = - 7

Hence the number is negative 7

Answer:

C = (-7,-5)

Step-by-step explanation:

Analysing the statements in the question, one after the other.

1. 7 units to the left of y axis

This implies that the x coordinate of C is -7

2. 5 units below the x axis.

This implies that the y coordinate of C is -5)

So,

C(x,y) = C(-7,-5)

Hence, the required coordinates of C is (-7,-5)
