There are three terms generally considered to be undefined in geometry: point, line and plane. A circle is the set of all points in a plane the same distance from a given point called the center. The only of our options that is used in this definition is plane.

Answer:

Length of side [tex]c[/tex]:

[tex]c = \rm AB \approx 115\; yds[/tex].

The distance across the canyon is approximately

[tex]\rm 113\;yds[/tex].

Step-by-step explanation:

Apply the law of sine:

[tex]\displaystyle \frac{c}{\sin{\rm A\hat{C}B} = \frac{a}{\sin{\rm B\hat{A}C}}[/tex].

In other words,

[tex]\displaystyle c = \sin{\rm B\hat{A}C} \cdot \frac{a}{\sin{\rm A\hat{C} B}}[/tex].

However, the value of the angle [tex]\rm B\hat{A}C[/tex] isn't given. Don't panic. The three interior angles of a triangle shall add up to 180°. Two of the three angles are given. The value of the third angle is implied.

[tex]\rm B\hat{A}C = 180\textdegree{} - A\hat{C}B - A\hat{B}C = 30\textdegree{}[/tex].

Apply the law of sine to find [tex]c[/tex]:

[tex]\displaystyle \begin{aligned}c &= \sin{\rm A\hat{C}B} \cdot \frac{a}{\sin{\rm B\hat{A}C}}\\ &= \sin{50\textdegree{}}\cdot \frac{\rm 75\; yds}{\sin{30\textdegree{}}}\\ &\rm = 114.907\; yds\end{aligned}[/tex].

Refer to the diagram. The distance across the canyon will be

[tex]\rm AB \cdot \sin{A\hat{B}C} = 114.907\times \sin{100\textdegree{}} \approx 113\;yds[/tex].

Answer:

  22 quarters

Step-by-step explanation:

Let q represent the number of quarters in the bank. Then 60-q is the number of nickels, and the total value of the coins is ...

  0.25q + 0.05(60 -q) = 7.40

  0.20q + 3.00 = 7.40 . . . . . . . . simplify

  0.20q = 4.40 . . . . . . . . . . . . . . subtract 3.00

  q = 4.40/0.20 = 22 . . . . . . . . . divide by the coefficient of q

There are 22 quarters in the piggy bank.

_____

Check

The other 60-22 = 38 coins are nickels, so the total value is ...

  0.25×22 + 0.05×38 = 5.50 + 1.90 = 7.40 . . . . . . the required amount

Step-by-step answer:

Here's a different way to solve the problem, mentally.

Mixture of 60 coins composed of nickels (5 cents) and quarters (25 cents).

Total value = 7.40.

IF all coins were quarters, value would be 60*0.25 = $15

That makes too many quarters.

To conform to the value of $7.40, we need to reduce the mix by $15-7.40 = 7.60.

Each exchange of quarters and nickels reduces the value by $0.25-0.05=0.20.

It takes 7.60 / 0.20 = 38 exchanges.

So there are 38 nickels and 22 quarters.

Both graphs have been shifted and flipped

Both graphs have exactly one asymptote

Step-by-step explanation:

Choice A is incorrect since both graphs are not logarithmic functions. The graph of f(x) appears to be an exponential function.

Choice B is also incorrect since both graphs are not exponential functions.  The graph of g(x) does not belong to the exponential family since y can take on negative values.

When the graph of f(x) is shifted downwards and flipped, we can obtain the graph of g(x).

Answer:

To maximize the income should be 30 buses and 150 cars

Step-by-step explanation:

Let

x-----> the number of cars

y ----> the number of bus

we know that

[tex]5x+32y\leq1,710[/tex] ------> inequality A

[tex]x+y\leq 180[/tex] ----> inequality B

The function of the cost to maximize is equal to

[tex]C=2x+6y[/tex]

Solve the system of inequalities by graphing

The solution is the shaded area

see the attached figure

The vertices of the solution are

(0,0),(0,53),(150,30),(180,0)

Verify

(0,53) ---> [tex]C=2(0)+6(53)=\$318[/tex]

(150,30) ---> [tex]C=2(150)+6(30)=\$480[/tex]

therefore

To maximize the income should be 30 buses and 150 cars

Answer:

Givens

To solve this problem we need to create a table to order all this information and express it as a system of inequations.

                     Car           Bus     Total Capcity

Sq. Meters      5c           32b            1710

N° vehicles      c              b                180                

Therefore, the inequalities are

[tex]5c+32b\leq 1710\\c+b\leq 180[/tex]

The expresion which represents the income is

[tex]I=2c+6b[/tex], because a car is $2.00 and a bus is $6.00.

Now, we first need to find the critical points of the solution of the inequality system, which is attached. Observe that the only points that can be a solution is (150,30), because there can't be just car or just buses.

Then, we replace this point in the income expression

[tex]I=2c+6b\\I=2(150)+6(30)=300+180=480[/tex]

Therefore, in order to maximize incomes, we need to park 150 cars and 30 buses, to make $480 income.

Answer:

center (1,-3) and radius is 5

Step-by-step explanation:

We have to use completing the square here:

x^2-2x    + y^2+6y         =15  (reorder some things and added 15 on both sides)

x^2-2x+(-2/2)^2  + y^2+6y+(6/2)^2   =15+(-2/2)^2+(6/2)^2 (whatever you add on one side you also do to the other side)

x^2-2x+(-1)^2   + y^2+6y+(3)^2=15+1+9

(x-1)^2         +    (y+3)^2          =25

Center is (1,-3) and radius is 5

ANSWER

The center is (1,-3) and the radius is r=5 units.

EXPLANATION

The given equation is:

[tex] {x}^{2} + {y}^{2} - 2x + 6y - 15 = 0[/tex]

Let rearrange to get:

[tex]{x}^{2} - 2x + {y}^{2} + 6y=15[/tex]

We complete the square to get;

[tex]{x}^{2} - 2x + ( { - 1)}^{2} + {y}^{2} + 6y + {3}^{2} = 15+ ( { - 1)}^{2} + {3}^{2}[/tex]

[tex] ( {x - 1)}^{2} +( {y + 3)}^{2} = 15 + 1+ 9[/tex]

[tex] ( {x - 1)}^{2} +( {y + 3)}^{2} =25[/tex]

[tex]( {x - 1)}^{2} +( {y + 3)}^{2} = {5}^{2} [/tex]

Comparing to

[tex]( {x - h)}^{2} +( {y - h)}^{2} = {r}^{2} [/tex]

The center is (1,-3) and the radius is r=5 units.

Answer:

see explanation

Step-by-step explanation:

(a)

The opposite sides of a rectangle are congruent, hence

x + 1 = 5 ( subtract 1 from both sides )

x = 4

Or

x - 1 = 3 ( add 1 to both sides )

x = 4

(b)

The sum of the 3 angles in a triangle = 180°, hence

3y + 2y + y = 180

6y = 180 ( divide both sides by 6 )

y = 30

Answer:

PART A "4"

PART B "30"

Step-by-step explanation:

PART A

If you refer to my picture below, then you will know that the sides are equal.

The x-1 side is equal to 3 and the x+1 sign is equal to 5. So it best makes sense that 4 is equal to x. That's because x-1 is 3 and x+1 is 5.

PART B

This is tricky. As you know all sides of a triangle add up to 180 degrees. I would divide by 3, but that would be incorrect. Whenever you see these y's, you have to divide by that amount. The y's are there for a reason, so that some sides are bigger than the other. Divide 180 by 6(number of y's). That is 30. This gives you the solution to one y so if it asks you for 2y or 3y, then you would multiply. But it's not. 30 is the answer

Answer:

A

Step-by-step explanation:

Choice A is right because there is no dot above the two.

Choice B is not right because there is 2 dots above 1 and not 3.

Choice C is not right because the data doesn't go passed 5 to get to 8

Choice D is not right because it was 5 games because there is 5 dots above 3

The answer would be A. the team never scored exactly 2 goals in a single game

If you look at the number two on the dot plot you can see that there are NO dots above it. This means that the team never scored exactly 2 goals.

It can't be B. because they scored exactly 1 goal for 2 games NOT 3

It can't be C.  because no where on the graph is the number 8. They never scored 8 goals. Five is actually the highest number of goals they ever scored.

It can't be D. because they scored 3 goals in a game for 5 games not for 4 games

  12(m -5) = 540

Step-by-step explanation:

The left side of the equation is in the form of a product. A suitable product is ...

  (calories/minute) × (minutes jogging) = (calories burned)

If m represent Anzelm's total minutes, then m-5 will represent the number of minutes actually jogging. This is what goes inside parentheses, so we have ...

  (12 calories per minute) × ((m -5) minutes) = 540 calories

Leaving off the units, which we know are consistent, we have ...

  12 (m -5) = 540

Answer:

12(m-5) = 540

Step-by-step explanation:

∵ The total calories have to burn = 540,

Also, here m represents the total time spent by Anzelm,

If he/she spent 5 minutes in rest,

Then the time he/she spent in jogging = (m - 5) minutes,

If the number of calories burnt in one minute = 12,

So, the number of calories burnt in (m-5) minutes = 12(m-5),

Therefore, for burning the whole calories,

Calories burnt by him/her = total calories

⇒ 12(m-5) = 540

Which is the required equation.

Answer:

Explanation:

In geometry, undefined terms refer to three entities: points, lines, and planes. They are considered undefined because they are rather described than formally defined.

The reason behind this lack of definition is that they are abstractions: you cannot touch or see a real point, line or plane.

A point represents a position in the plane or the space, and it is dimensionless. Yet it is used to define a line and a plane.

Among those three terms, only line and plane meet the feature of not having begin or end. That is so because lines  and planes extend infinetly

LInes extend in two directions, in one dimension: for example, from left to right, or from east to west, or vertically.

Planes extend infinetly in two dimensions: they are flat infinite surfaces.

C.) y = - 8

Step-by-step explanation:

If the line has a slope of 0, it is a horizontal line.  That means y= a value

Since we have the point (0,-8)

y = -8

Final answer:

The equation of a line that goes through point (0, -8) with a slope of 0 is y = -8.(Option c)

Explanation:

We need to find the equation of a line that goes through the point (0, -8) and has a slope of 0. The general equation for a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. Since the slope (m) is 0, the line is horizontal.

A horizontal line has an equation of the form y = b, where b is the y-coordinate of every point on the line. As the line goes through (0, -8), we can see that the y-coordinate is -8 for all points on this line. Therefore, the equation of this line is C) y = -8.
