-10x+18=-10x-18

18=-18

Since the equation is inconsistent and has no solution, there is no value of x that would make it true.

Step-by-step explanation:

Answer:

The answer would be 8.1% (8.108% if you need the exact percentage.)

Step-by-step explanation:

All you would need to do is add 7 + 18 + 12 which = 37, and divide 3/37, which in percentage that gives you 8.1%. (8.108% if you need exact percentage.)

The equation of the hyperbola x²/36 = 1. The equation of a horizontal line passing through (±6,0).

The resulting curve of a hyperbola consists of two separate branches that are mirror images of each other, and they are characterized by their asymptotes, which are straight lines that the curve approaches but never touches. The asymptotes intersect at the center of the hyperbola, which is also the point where the two branches are closest together.

Since the foci of the hyperbola are at (0,-6) and (0,6), and the transverse axis is vertical, the center of the hyperbola is at the midpoint of the foci, which is the point (0,0).

Also, since the asymptote of the hyperbola is the line y = -x, we know that the slopes of the asymptotes are ±1, and since the transverse axis is vertical, the slope of the transverse axis is 0. Therefore, we have a hyperbola with center (0,0), vertical transverse axis, and asymptotes y = x and y = -x.

The standard form of the equation for a hyperbola with center (0,0), transverse axis of length 2a, and asymptotes y = ±(a/x) is:

x²/a² - y²/b² = 1

where b² = a² - c², where c is the distance from the center to each focus.

In this case, since the distance between the foci is 12, we have:

c = 6

Also, since the transverse axis is vertical and the distance from the center to each vertex is a, we have:

a = distance from center to vertex = 6

Therefore, we have:

b² = a² - c² = 36 - 36 = 0

So the equation of the hyperbola is:

x²/36 - y²/0 = 1

Simplifying, we get:

x²/36 = 1

or

x² = 36

This is the equation of a horizontal line passing through (±6,0).

Answer:

Step-by-step explanation:

Expected Value = (Probability of winning) x (Amount won) + (Probability of losing) x (Amount lost)

In this case, the probability of winning is 1/6 (since there is only one way to roll a 3 out of six possible outcomes), and the probability of losing is 5/6 (since there are five other outcomes that do not result in a win).

The amount won is $15, and the amount lost (i.e., the cost of playing the game) is $3.

Therefore, the expected value is:

Expected Value = (1/6) x $15 + (5/6) x (-$3)

Expected Value = $2.50 - $2.50

Answer:

(x, y) = (-1/2, 5/2)

Step-by-step explanation:

To solve this system of equations using substitution, we can use the first equation to express y in terms of x, and then substitute that expression into the second equation to get an equation in terms of x alone.

Starting with the first equation, we have:

y = x + 3

We can now substitute this expression for y into the second equation:

3x + 3y = 6

3x + 3(x + 3) = 6

Simplifying the right-hand side:

3x + 3x + 9 = 6

6x = -3

x = -1/2

Now that we have solved for x, we can substitute this value back into the first equation to find y:

y = x + 3

y = -1/2 + 3

y = 5/2

Therefore, the solution to the system of equations is (x, y) = (-1/2, 5/2).

To check our solution, we can substitute these values back into both equations and verify that they hold true:

y = x + 3

5/2 = -1/2 + 3

5/2 = 5/2

This equation holds true, so the first equation is satisfied by our solution.

3x + 3y = 6

3(-1/2) + 3(5/2) = 6

-3/2 + 15/2 = 6

6 = 6

This equation also holds true, so the second equation is satisfied by our solution as well.

Therefore, we can conclude that our solution is correct.

The equations have two variables, x and y, and we can use substitution to solve for one variable in terms of the other. By substituting the expression for y into the second equation and solving for x, we get the value of x as -1/2. We can then substitute this value back into the first equation to get the value of y, which is 5/2. This means that the solution to the system of equations is (x, y) = (-1/2, 5/2) and we can check that this solution satisfies both equations.

The height of the can should be approximately 7 inches to have a surface area as close to 100 square inches as possible.

What is cylinder?

A cylinder is a three-dimensional geometric shape that consists of two parallel circular bases of the same size and shape, and a curved lateral surface connecting the bases.

The formula for the surface area of a cylinder is:

where r is the radius of the base, h is the height, and π is approximately 3.14.

In this case, the radius is given as 2 inches, and we want to find the height that will give us a surface area as close to 100 square inches as possible. So we need to solve for h in the equation:

100 = 2π(2)² + 2π(2)h

Simplifying this equation:

100 = 8π + 4πh

92 = 4πh

h = 23/π

h ≈ 7.32

Rounding this answer to the nearest inch, we get:

h ≈ 7 inches

Therefore, the height of the can should be approximately 7 inches to have a surface area as close to 100 square inches as possible.

A prοbability is a numerical representatiοn οf the likelihοοd οr chance that a specific event will take place. Bοth prοpοrtiοns ranging frοm 0 tο 1 and percentages ranging frοm 0% tο 100% can be used tο describe prοbabilities.

Let X be the number οf False answers in the cοmpleted exam paper.

Prοbability that all answers are False:

[tex]P(X = 4) = (0.5)^4 = 0.0625[/tex]

Prοbability that exactly three οr fοur answers are False:

P(X = 3 οr X = 4) = P(X = 3) + P(X = 4)

[tex]= 4C3(0.5)^3(0.5)^1 + (0.5)^4[/tex]

= 0.3125

Prοbability that at least οne answer is True (which is the cοmplement οf the event that all answers are False):

P(at least οne True) = 1 - P(all False) = 1 - 0.0625 = 0.9375

Prοbability that the last answer is True:

This prοbability can be calculated using cοnditiοnal prοbability, where we find the prοbability that the last answer is True given that we knοw that at least οne answer is True:

P(last answer is True | at least οne True) = P(last answer is True and at least οne True) / P(at least οne True)

P(last answer is True and at least οne True) = P(last answer is True) = 0.5

P(at least οne True) = 0.9375 (calculated in part 3)

From the table, we see that Julia rolled the die 100 times, and the number of times she rolled a 3 was 45.

The best estimate of the probability of rolling a 3 can be found by dividing the number of times a 3 was rolled by the total number of rolls:

P(rolling a 3) = Number of times 3 was rolled / Total number of rolls

P(rolling a 3) = 45 / 100

P(rolling a 3) = 0.45 or 45%

Therefore, based on Julia's experimental results, the best estimate of the probability of rolling a 3 on her biased die is 0.45 or 45%.

b.  It tell us that the drone and rocket are at the same height at that time.

A function notation is the representation of a statement as a mathematical equation using symbols.

Part 1

a. To write the statement at 3 seconds the toy rocket is higher than the drone in function notation.

Since

At t = 3, the toy rocket is higher than the drone.

So, in function notation, we have that R(3) > D(3)

b. To write the statement at the start the toy rocket is 25 feet above the drone.

At the start t = 0, and the toy rocket is 25 feet above the drone.

So, in function notation, we have that R(0) - D(0) = 25

Part 2.

To find the height of the drone when the rocket hit the ground,

Since

We find R(t) = 0 and find the time t, where it intercepts the height of the drone.

So, from the graph R(t) = 0 at t = 5. And at t = 5, D(t) = 20

So, the drone is 20 feet above the ground when the rocket hit the ground.

Part 3.

a. The value of t at which R(t) = D(t) is where the graphs intercept.

The graphs intercept at t = 4.75 s

Answer:

To prove that every bounded sequence contains a convergent subsequence, we will use the Bolzano-Weierstrass theorem.

Bolzano-Weierstrass theorem: Every bounded sequence in Euclidean space has a convergent subsequence.

Proof: Let (a_n) be a bounded sequence in Euclidean space, which means that there exists some M > 0 such that |a_n| <= M for all n. We will use the bisection method to construct a subsequence that converges to some limit L.

Step 1: Divide the interval [-M, M] into two subintervals, [-M, 0] and [0, M]. Since (a_n) is bounded, at least one of these intervals contains infinitely many terms of the sequence. Let's call the interval that contains infinitely many terms I_1.

Step 2: Divide I_1 into two subintervals of equal length, and again, at least one of these subintervals must contain infinitely many terms of the sequence. Let's call the interval that contains infinitely many terms I_2.

Step 3: Repeat this process for each subinterval, dividing it into two subintervals of equal length and choosing the one that contains infinitely many terms of the sequence. We obtain a sequence of nested intervals I_1 ⊃ I_2 ⊃ I_3 ⊃ ... that contain infinitely many terms of the sequence.

Step 4: Since the length of each interval is decreasing and they are nested, the intersection of all the intervals is a single point L. By construction, every term of the sequence (a_n) belongs to one of the intervals I_k, which means that there exists a subsequence (a_nk) that converges to L.

Therefore, every bounded sequence in Euclidean space has a convergent subsequence, as required.

So, if you draw this down, you will see that the direct distance is hypotenuse c of a right triangle which sides are 3 blocks (1 south and 2 north) and 7 blocks (4 west and 3 east).

Use the Pythagorean theorem:

[tex]c^2 = a^2 + b^2[/tex]

[tex]a = 3[/tex]

[tex]b = 7[/tex]

[tex]c^2 = 3^2 + 7^2[/tex]

[tex]c^2 = 9 + 49[/tex]

[tex]c^2 = 58[/tex]

[tex]c = \sqrt{58}[/tex]

[tex]c = 7.62[/tex]

Answer: We can simplify the given expression as follows:

9√64 - 2√125

Since √64 = 8, we can substitute to get:

9(8) - 2√125

Since √125 = √(25 × 5) = √25 × √5 = 5√5, we can substitute again to get:

9(8) - 2(5√5)

Simplifying further:

72 - 10√5

Therefore, the expression 9√64 3 − 2√125 simplifies to 72 - 10√5.

[tex]\frac{2}{2}[/tex] + [tex]\frac{1}{2}[/tex] = [tex]\frac{3}{2}[/tex]      1 is the same as [tex]\frac{2}{2}[/tex]

Now we have

96 is equal to [tex]\frac{192}{2}[/tex]   ([tex]\frac{96}{1}[/tex] x [tex]\frac{2}{2}[/tex])

Now we have

[tex]\frac{192}{2}[/tex] ÷ [tex]\frac{3}{2}[/tex] =  [tex]\frac{64}{1}[/tex] = 64

We now know the unit rate is 64 miles in one hour.
