Simonne used the following steps to simplify the given expresion 12 minus 3 (negative 2 x + 4)

The probability of both coins landing on heads when two coins are tossed is 1/4, or 0.25, or 25%.

When two coins are tossed, there are four possible outcomes: both coins can land on heads (HH), both coins can land on tails (TT), the first coin can land on heads and the second coin on tails (HT), or the first coin can land on tails and the second coin on heads (TH).

Since we are interested in the probability of both coins landing on heads, we need to determine the number of favorable outcomes (HH) out of the total number of possible outcomes.

Out of the four possible outcomes, only one outcome is favorable (HH). Therefore, the probability of both coins landing on heads is 1 out of 4.

In fraction form, this can be written as 1/4. The probability can also be expressed as a decimal, which is 0.25, or as a percentage, which is 25%.

It's important to note that in this case, we assume that the coins are fair and unbiased, meaning that the probability of landing on heads is equal to the probability of landing on tails, which is 1/2 or 0.5 for each coin individually.

Answer:

C.) a great circle

Step-by-step explanation:

Answer:

  C:  y = -(x +3)² -1

Step-by-step explanation:

You want the vertex-form equation of the parabola with vertex (-3, -1) and opening downward.

For vertex (h, k), the vertex form equation of a parabola is ...

  y = a(x -h)² +k

Given that (h, k) = (-3, -1), the equation will have the form ...

  y = a(x -(-3))² + (-1)

  y = a(x +3)² -1 . . . . . . . . . . matches choice C

The value of 'a' will be negative when the parabola opens downward. Here, its value is -1.

  y = -(x +3)² -1

__

Additional comment

Once you identify the left-shift of 3 units as resulting in an equation with (x +3)² as a component, you can make the appropriate answer choice without considering anything else. Of course, the fact that the curve opens downward immediately eliminates choices A and B.

Answer:

C) 6 cm.

Step-by-step explanation:

Let's define some variables.
Let AH = h, MH = x.

The attached file is a drawing of the givens.

A triangle's area is found using the formula [tex]A = \frac{b \times h}2[/tex], where:
A = The area of the triangle
b = The base of the triangle
h = The height of the triangle (In our case, AH)

We'll use the given lengths and area of triangle TAH to find the height:

[tex]12 = \frac{8 \times h}2\\12 = 4h\\h = 3[/tex]

We will now do the same but with triangle MAH to find MH:

[tex]9 = \frac{3 \times x}2\\18 = 3x\\x = 6[/tex]

The length of MH is 6 cm.

Kenneth's speed given that he was able to walk 2 miles in 40 minutes was 0. 05 miles per minute.

To calculate Kenneth's speed, there is a need to divide the distance he walked by the time it took. This would show how fast he was walking such that he could cover the distance in that time.

Kenneth walked 2 miles in 40 minutes.

His speed was therefore:

Speed = Distance / Time

Speed = 2 miles / 40 minutes

Speed = 0. 05 miles per minute

In conclusion, Kenneth's speed is 0. 05 miles per minute.

1. The distance from the center of the planet to the satellite is approximately 17658 miles.

2. Approximately 2.61% of the planet's equator is within range of the satellite's signal.

3. It takes approximately 0.1005 seconds longer for the satellite signal to reach point B compared to point E.

4. The satellite must travel at approximately 8 miles/second to complete one revolution in 36 hours.

To solve these problems, use basic geometric principles and formulas.

1. Finding the distance: From the information given, we can see that the radius of the planet is 3,500 miles, and the distance from the edge of the planet to the satellite is 18,000 miles. Use the Pythagorean theorem to find the distance from point A to point C (the center of the planet).

Consider the right triangle ABC, where AB is the radius of the planet, BC is the distance from the edge of the planet to the satellite, and AC is the distance from the center of the planet to the satellite.

Using the Pythagorean theorem:

AC² + AB² = BC²

Substituting the known values, we get:

AC² + 3500² = 18000²

AC² = 18000^2 - 3500^2

AC² = 324000000 - 12250000

AC² = 311750000

Taking the square root of both sides, we find:

AC = √311750000

AC ≈ 17658 miles (rounded to the nearest mile)

Therefore, the distance from the center of the planet to the satellite is approximately 17658 miles.

2. Finding the percentage of the planet's equator within range of the satellite's signal:

To find the percentage of the planet's equator within range of the satellite's signal, we need to calculate the angle subtended by the distance between points B and D (i.e., the arc BD) at the center of the planet.

The circumference of the circle represents the planet's equator. Since the distance between points B and D represents the greatest distance at which the signal can be received directly, it corresponds to the arc length of the signal's coverage.

Using the formula for the circumference of a circle, C = 2πr, calculate the circumference of the planet's equator:

C = 2π(3500)

C ≈ 21991 miles (rounded to the nearest mile)

Now, calculate the angle m∠BAC in degrees:

m∠BAC = 9.4°

To find the length of the arc BD, use the formula for the circumference of a circle and convert the angle to radians:

Arc length = (angle in radians) × (radius of the circle)

Arc length = (9.4° / 360°) × (21991 miles)

Arc length ≈ 573.24 miles (rounded to the nearest hundredth)

Therefore, the signal covers an arc length of approximately 573.24 miles along the planet's equator.

To find the percentage of the planet's equator within range of the satellite's signal, divide the arc length by the circumference of the equator and multiply by 100:

Percentage = (Arc length / Circumference of equator) × 100

Percentage = (573.24 / 21991) × 100

Percentage ≈ 2.61% (rounded to two decimal places)

Therefore, approximately 2.61% of the planet's equator is within range of the satellite's signal.

3. Finding the time difference between point B and point E:

To find the time difference between point B and point E, calculate the difference in distances divided by the speed of the satellite signal.

The distance from the satellite to point B is the radius of the planet plus the distance from the edge of the planet to the satellite:

Distance from A to B = 3500 + 18000 = 21500 miles

The distance from the satellite to point E is

the radius of the planet:

Distance from A to E = 3500 miles

Using the formula: Time = Distance / Speed, we can calculate the time difference:

Time difference = (Distance from A to B - Distance from A to E) / Speed

Time difference = (21500 - 3500) / 186000

Time difference ≈ 0.1005 seconds (rounded to the nearest hundredth)

Therefore, it takes approximately 0.1005 seconds longer for the satellite signal to reach point B compared to point E.

4. Finding the speed of the satellite:

The time taken for one complete revolution by the satellite is given as 36 hours. To find the speed of the satellite, we need to convert the time to seconds and calculate the distance traveled during that time.

Given:

Time for one revolution = 36 hours

Speed of light = 186,000 miles/second

First, let's convert the time to seconds:

Time = 36 hours × 60 minutes/hour × 60 seconds/minute

Time = 36 × 60 × 60 seconds

Time = 129,600 seconds

During one complete revolution, the satellite travels the circumference of the circle with a radius equal to the distance from the center of the planet to the satellite.

Circumference = 2π × (distance from the center of the planet to the satellite)

Circumference = 2π × 17658 miles

Speed = Circumference / Time

Speed = (2π × 17658 miles) / 129,600 seconds

Calculating this value:

Speed ≈ 8.134 miles/second (rounded to the nearest whole number)

Therefore, the satellite must travel at approximately 8 miles/second to complete one revolution in 36 hours.

Probability that a blue marble is chosen and then a black marble is 1/6 .

Given,

So,

Total number of marbles: 15 + 7 + 3 + 5 = 30

The probability of taking one blue marble is: 15/30

The probability of taking a black marble is: 5/30

(Note: since we are replacing the first marble, the total is staying constant i.e. 16)

We might draw a blue marble and then a black one, or, a black one and then a blue one. This implies that the probability will be:

(15/30 x 5/30) + (5/30 x 15/30) = 1/6

The value of x that satisfies the equation x = 12 log₆ (8x) is x = 0.

We have,

To find the value of x in equation x = 12 log₆ (8x), we can solve it algebraically.

Here's how:

Start by isolating the logarithm term by dividing both sides of the equation by 12:

x/12 = log₆ (8x)

Now, rewrite the logarithmic equation in exponential form:

6^(x/12) = 8x

Apply the properties of exponents to simplify the equation further:

(2^3)^(x/12) = (2^3)^x

2^(3x/12) = 2^(3x)

Since the bases are equal, we can equate the exponents:

3x/12 = 3x

Next, cross-multiply to get rid of the fraction:

3x = 12 * 3x

Simplify:

3x = 36x

Subtract 36x from both sides:

3x - 36x = 0

Simplify:

-33x = 0

Divide both sides by -33:

x = 0

Answer:

64:343

Step-by-step explanation:

The ratio of the volume of the small pyramid to the volume of the large pyramid is equal to the cube of the ratio of their corresponding linear dimensions.

In this case, the ratio of the heights is 4/7, so the ratio of the volumes is (4/7)^3 = 64/343.

Therefore, the ratio of the volumes of the two pyramids is 64:343.

Here is a more detailed explanation:

The volume of a pyramid is given by the formula:

V = ⅓*Bh

where V is the volume, B is the area of the base, and h is the height.

Since the two pyramids are similar, the ratio of their areas is equal to the square of the ratio of their corresponding ki linear dimensions.

In this case, the ratio of the heights is 4/7, so the ratio of the areas is (4/7)^2 = 16/49.

Therefore, the ratio of the volumes of the two pyramids is:

(1/3) * (16/49) * (4/7) = 64/343

In slope intercept form, the line's equation is y = 2x + 1. We must apply the formula y = mx + b to formulate an equation in slope intercept form. The slope of the line is represented by m, while the y-intercept is represented by b.

We need two locations on the line to find the slope. Assume we have points (2,5) and (4,9). We may calculate the slope using the following formula:

m = (9 - 5) / (4 - 2) m = (9 - 5) / (4 - 2)

m = 2

As a result, the slope of the line is 2.

We must now identify the y-intercept, which is the point at where the line crosses the y-axis.

We can utilise one of the points we already have to discover this. Let's start with (2,5).

y = mx + b

5 = 2(2) + b

5 = 4 + b

b = 1

As a result, the y-intercept is 1.

Now we can enter the numbers we discovered for m and b into the formula:

y = mx + b

y = 2x + 1

As a result, the slope intercept form equation of the line is y = 2x + 1.
