Answer:

  see below for instructions

Step-by-step explanation:

You will need to do these constructions yourself. We cannot put marks on your paper for you.

The instructions below apply to part 3. A subset of the instructions applies to parts 1 and 2. The tools you need are a compass and a straightedge.

__

1. Draw line AB, and mark point X on it.

2. Choose a suitable radius for your compass and draw arcs with that radius centered at X. Label the points of intersection with line AB points E and G.

__

From here, the instructions are the same for constructing a perpendicular bisector of any segment. In what follows, we are construction the perpendicular bisector of segment EG. Thus, these instructions apply directly to parts 1 and 2. Points E and G will refer to the end points of the segment you are bisecting.

3. Set your compass radius to more than half the distance between points E and G.

4. Draw an arc centered at E that extends above and below the center of segment EG.

5. Using the same radius, draw arcs centered at G that cross the arc you drew in step 4. Label the points of intersection point P and Q.

6. Draw line segment PQ. This is the perpendicular bisector of EG. (For part 3, it will go through point X.)

__

In the attached, we show the "arcs" as full circles. They need not be. They only need to have sufficient length to make sure they cross where they need to cross.

Answer:

a = [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

When working with fractions, I would mostly like to make the denominators the same first.  

[tex]\frac{2}{3}[/tex]a - [tex]\frac{1}{6}[/tex] = [tex]\frac{1}{3}[/tex]

Make all the denominators 6.

[tex]\frac{4}{6}[/tex]a - [tex]\frac{1}{6}[/tex] = [tex]\frac{2}{6}[/tex]

Isolate [tex]\frac{4}{6}[/tex]a.

[tex]\frac{4}{6}[/tex]a = [tex]\frac{2}{6}[/tex] + [tex]\frac{1}{6}[/tex]

   = [tex]\frac{3}{6}[/tex]

Find a.

[tex]\frac{6}{6}[/tex]a = [tex]\frac{6}{4}[/tex] × [tex]\frac{3}{6}[/tex]

a = [tex]\frac{3}{4}[/tex]

The average rate of change of f(x) = 1/(x + 12) on the given interval is expressed as: [tex]\frac{-1}{19(h + 19)}[/tex]

Given the function, f(x) = 1/(x + 12), the average rate of change of f(x) on the interval, [7, 7 + h], can be calculated using the formula:

Average rate of change = f(b) - f(a)/b - a.

a = 7

f(a) = f(7) = 1/(7 + 12) = 1/19

b = 7 + h

f(b) = f(7 + h) = 1/(7 + h + 12) = 1/(h + 19)

Plug in the values into the average rate of change formula

Average rate of change = 1/(h + 19) - 1/19 ÷ 7 + h - 7

Average rate of change = [19 - (h + 19)]/19(h + 19) ÷ h

Average rate of change = (19 - h - 19)/19(h + 19) × 1/h

Average rate of change = -h/19(h + 19) × 1/h

Average rate of change = -1/19(h + 19) × 1/1

Average rate of change = [tex]\frac{-1}{19(h + 19)}[/tex]

Therefore, the average rate of change of f(x) = 1/(x + 12) on the given interval is expressed as: [tex]\frac{-1}{19(h + 19)}[/tex].

Answer:

The Length is 56 feet

Step-by-step explanation:

w + w + 8 + w + 8 + w = 208  (two sides have a width of w and 2 sides have the length of 8 + w)

Combine the w/s and the 8's

4w + 16 = 208  Subtract 16 from both sides of the equation

4w = 192  Divide both sides by 4

w = 48  The width is 48 feet.  That means that the length is 8 feet longer or 56 feet.

Check:

48 + 48 + 56 + 56 = 208

208 = 208

11 pound turkey

Answer:

Answer: 8√3.

Step-by-step explanation:

First, look for any perfect squares that can fit into 192 snugly.

If we look for factors of 192, we can discover that the largest perfect square that can fit into it is 64 (and 3).

The √ of 64 is 8.

The √ of 3 cannot be simplified any further.

Thus, leaving us with our answer of 8√3.

Answer:

The coordinates of ABC are respectively (-2,2), (-2,3), and  (1,2).

Step-by-step explanation:

Dilation About the Origin

Given a point P(x,y), its dilation about the origin by a scale factor of k maps the point to a point P'(kx,ky).

If we are given the dilated point, then we can find the original point by dividing by the scale factor.

Triangle ABC was dilated by a scale factor of 2 about the origin mapping it to triangle A'B'C' with vertices A'(-4,4), B'(-4,6), and C(2,4).

The coordinates of triangle ABC are:

A=(-4/2,4/2) = (-2,2)

B=(-4/2,6/2) = (-2,3)

C=(2/2,4/2) = (1,2)

The coordinates of ABC are respectively (-2,2), (-2,3), and  (1,2).

Answer:

The coordinates of ABC are  (-2,2), (-2,3), and  (1,2).

Given that,

Total number of snails shells and shark teeth = 60

The ratio of snail shells to shark teeth is 5:1

To find,

Total no of snail shells used by the Jeweler.

Solution,

Let there are 5x snail shells and x shark shells.

According to question,

5x+x = 60

6x = 60

x = 10

Snail shell = 5x

= 5(10)

= 50

Hence, he uses 50 snail shells.

The hospital can get 4.15 milligrams from these three companies.

A linear equation is one in which the highest power of any variable is not more than 1. A linear equation in 2 variables can be solved by substitution method, if we have two simultaneous equations.

Here, we know that

Company A's supply of medicine = 1.7 mg

also, company A's supply = 2( B's supply - C's supply)

⇒ 1.7 = 2( B - C)

⇒ 1.7 = 2B - 2C .... (1)

Moreover, we are given that

A's supply = C's supply + 0.9

⇒ 1.7 = C + 0.9

⇒ 1.7 - 0.9 = C

⇒ 0.8 = C

Now, substituting the value of C in (1), we get,

1.7 = 2B - 2(0.8)

1.7 = 2B - 1.6

1.7 + 1.6 = 2B

⇒ B = 3.3/2

B = 1.65

Thus, the total supply from all three companies is (1.7 + 1.65 + 0.8) = 4.15 mg
