The radar system in an airport determines the location of inbound and outbound planes once they are within range. The range, based on the signal from the tower, is represented by the polar equation r = 10cos(θ). Which graph represents the signal range of the airport’s radar system?

Answer:

Infinite solutions.

Any number.

Step-by-step explanation:

First, substitute one of the variables, x or y into one of the equations.

Since y is already isolated, substitute it in 2y - 6x = -8.

2 (3x - 4) - 6x = -8

Distribute 2 to 3x and -4.

6x - 8 - 6x = -8

Bring like terms together.

6x - 6x - 8 = -8

move -8 over to the other side of the equation and change its sign.

Or just add 8 to both sides (it is the same thing.)

You add 8 because it is to cancel out the negative 8 and get rid of it.

6x - 6x = -8 + 8

This equals 0 = 0 so there are infinite solutions to this system of equations.

Answer:

[tex]x ^{2} + 6x + 9 \\ \: = x ^{2} + (3 + 3)x \: + 9 \\ = x {}^{2} + 3x + 3x \: + 9 \\ \: \: \: \: = x(x + 3) + 3(x + 3) \\ = (x + 3) \: \: \: \: \: (x + 3)[/tex]

So, the Answer is (x + 3) (x + 3)

Answer: 3x + 3

We have

using a graph tool

see the attached figure

The solution of the system is the shaded area

we know that

The line is solid

The line passes through points and and is shaded above the line.

The line is solid

The line passes through points and and is shaded below the line

The two lines intersect at one point

therefore

the answer is the option

B) Graph of two lines that intersect at one point. Both lines are solid. One line passes through points negative 2, 2 and 0, 3 and is shaded below the line. The other line passes through points 0, 1 and 1, negative 2 and is shaded above the line.

Rational numbers can be expressed as fractions of integers. Negative 22 and 99 are both integers, therefore the number is rational!

Explanation:

The term "bisect" means "divide in half", or "divide in two equal pieces".

Angles A = 58 and B = 96 divide in half to get 29 and 48 respectively

Find their sum and subtract it from 180 to get angle AMB

29+48 = 77

180-77 = 103

Answer:

x = 3

Step-by-step explanation:

This is in vertex notation which means that it is written in y = (x-h)^2 + k format where the vertex is (h,k). In this case the vertex is (3,2) which means that at the x-axis of 3, that is where the parabola is mirrored and is in fact the axis of symmetry

Answer: Knowing proportional relationships help in different ways such as in constant change, multiple representations, etc.

Hope this helped.

Answer:

m = 7

Step-by-step explanation:

An angle bisector is a line or ray that divides an angle into two equal angles

so ∠WXZ = ∠ZXY

10m - 28 = 5m + 7

10m - 5m = 7 + 28

5m = 35

m = 7

Katie requires 16/3 cups of the soil for planting a garden for her science fair.

Algebra is a mathematical technique for calculating unknown values.

Now, for the stated question;

Katie has been planting a garden for her science fair project. She requires 2/3 of a cup of soil for each of the eight pots.

To calculate the total amount of soil required, multiply the amount required for one pot by the number of total pots.

Total soil  = (2/3)×8

Total soil  = (2×8)/3

Total soil  = 16/3

Therefore, the total amount of the soil requires for the gardening in science fair is 16/3 cups.

Answer:

(1, 4)

Step-by-step explanation:

5x-2y=-3 -2x-y=-6  =>

5x-2y=-3

-2x-y=-6   Multiply all three terms by -2:  4x + 2y = 12

Then we have:

5x-2y=-3

4x + 2y = 12

---------------------

 9x = 9 and so x = 1.  Then, using -2x - y = -6,  and substituting 1 for x:

-2(1) - y = -6, or

2 + y = 6, or

y = 4

Then the solution is (1, 4)

Answer:

Step-by-step explanation:

The formula for the volume of a cylinder is ...

  V = πr^2·h . . . radius r, height h

The radius of the driver's tank is half its diameter, so is (8 ft)/2 = 4 ft. Then the volume of that tank is ...

  V = π(4 ft)^2·(19 ft) = 304π ft^3

Each cubic foot of gasoline has a mass of ...

  (1728 in^3/ft^3)(0.0262 lb/in^3) = 45.2736 lb/ft^3

Then the total mass in the driver's full tank is ...

  (304π ft^3)(45.2736 lb/ft^3) ≈ 43,238.3 lb

__

The farmer's tank is a scaled-down version of the driver's tank. It's volume will be scaled by the cube of the linear scale factor, so will be (2/3)^3 = 8/27 of the volume of the driver's tank.

The farmer's tank will hold a mass of (43,238.3 lb)(8/27) ≈ 12,811 lb.

The amount remaining in the driver's tank is 43,238 -12,811 = 30,427 lb.

in order to figure out if we can pay the car, we need to know how much it costs.
