Step-by-step explanation:

1)

d² = (6-1)²+(3-1)²

or, d² = 5²+2²

or, d² = 25+4

so, d² = 29

so, d = 5.4 units

2)

d² = (4+2)²+(3-1)²

or, d² = 6²+2²

or, d² = 36 + 4

so, d² = 40

so, d = 6.3 units

3)

d² = (3-1)²+(-2-1)²

or, d² = 2²+(-3)²

or, d² = 4+9

or, d² = 13

so, d = 3.6 units

Answer:

The plant will grow 15 inches in 10 months.

Step-by-step explanation:

The given information is 6 inches = 4 months, and that may not sound like much but we can get the answer just from that tidbit.

Cross multiply :

[tex]\frac{6 inches}{4 months}[/tex] = [tex]\frac{x}{10 months}[/tex]

4x = 60

Divide by 4 on both sides.

x = 15.

Therefore the plant will grow 15 inches in 10 months. Please mark brainliest! :)

Answer:

1.   x² + y² + 8x - 14y - 35 = 0

2.  x² + y² - 2x - 8y - 47 = 0

3.  x² + y² - 4x - 2y - 116 = 0

4.  x² + y² + 2x + 4y - 20 = 0

5.  x² + y² - 4x - 8y - 52 = 0

Step-by-step explanation:

General equation of a circle is:  x² + y² + 2gx + 2fy + c = 0

with center (-g, -f) and radius √(g² + f² - c)

1.  From inspection:  center (-4, 7)  and radius = √100 = 10

   Therefore, g = 4  and  f = -7

   √(4² + (-7)² - c) = 10  ⇒  65 - c = 100  ⇒  c = -35

   So,  x² + y² + 8x - 14y - 35 = 0

2.  From inspection:  center (1, 4)  and radius = √64 = 8

   Therefore, g = -1  and  f = -4

   √((-1)² + (-4)² - c) = 8  ⇒  17 - c = 64  ⇒  c = -47

   So,  x² + y² - 2x - 8y - 47 = 0

3.  From inspection:  center (2, 1)  and radius = √(11²) = 11

   Therefore, g = -2  and  f = -1

   √((-2)² + (-1)² - c) = 11  ⇒  5 - c = 121  ⇒  c = -116

   So,  x² + y² - 4x - 2y - 116 = 0

4.  From inspection:  center (-1, -2)  and radius = √25 = 5

   Therefore, g = 1  and  f = 2

   √(1² + 2² - c) = 5  ⇒  5 - c = 25  ⇒  c = -20

   So,  x² + y² + 2x + 4y - 20 = 0

5.  From inspection:  center (2, 4)  and radius = √72

   Therefore, g = -2  and  f = -4

   √((-2)² + (-4)² - c) = √72  ⇒  20 - c = 72  ⇒  c = -52

   So,  x² + y² - 4x - 8y - 52 = 0

Answer:

Each box is 15.99

Step-by-step explanation:

Just the divide the total cost by 6

Answer:

Equation : b = $95.94/6

the cost per box is $15.99.

Step-by-step explanation:

For the first question, we need to create an equation to determine the cost per box. Let us assign "b" to represent the cost per box and the solution is shown below:

b= $95.94/6

95.94 divided by 6 is 15.99.

Therefore, the cost per box is $15.99.

Answer:

1.    [tex]x[/tex] = 3√10     2.  [tex]x[/tex] = 5      3.   [tex]x[/tex] = 6√2

Step-by-step explanation:

Use Intersecting Secant-Tangent Theorem:

If a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.

1.  In this circle, DB is a tangent and DA is a secant.  They intersect at point D.

So  DB² = DC x DA

    [tex]x[/tex]² = 5 x (5 + 13)

    [tex]x[/tex]² = 90

     [tex]x[/tex] = √90 = 3√10

2.  In this circle, FE is a tangent and FH is a secant.  They intersect at point F.

So  FE² = FG x FH

      10² = [tex]x[/tex] x 20

     100 = 20[tex]x[/tex]

         [tex]x[/tex] = 5

3.  In this circle, NM is a tangent and NP is a secant.  They intersect at point N.

So  NM² = NO x NP

    [tex]x[/tex]² = 4 x (4 + 14)

    [tex]x[/tex]² = 72

     [tex]x[/tex] = √72 = 6√2

Answer:

m∠Z1 = 93°

Step-by-step explanation:

Vertical Angles are the angles opposite each other when two lines cross.

They are congruent (the same as each other).

Therefore, m∠Z1 = m∠Z2, so if  m∠Z2 = 93° then m∠Z1 = 93°

The measure of ∠1 is 93 degrees

What are vertical angles ?

Vertical angles are a pair of opposite angles formed by intersecting lines. Vertical angles are opposite each other and they share the same vertex point.

Vertical angles are always congruent.

Therefore, since ∠1 and ∠2 are vertically opposite angles this means they are congruent.  

Therefore,

∠1 ≅ ∠2

∠2 = 93°

∠1 = 93°
