Mei-Ling has paints in 4 different colors. If she is going to paint the inside of a box with one color and the outside of the box with another color, in how many different ways can she paint the box?​

Answer: b+95+34=180, b+129=180, 51

Step-by-step explanation:

b+95+34=180 works because the angles add to form a straight angle.

From this, we can obtain b+129=180 by adding the two constants.

Subtracting 129 from both sides, we get b=51.

True, The range of a linear transformation defined by the matrix transformation t(x) = Ax is equal to the column space of matrix A.


The range of a linear transformation defined by the matrix transformation t(x) = ax is equal to the column space of matrix A (col A).

The range of a linear transformation is the set of all possible output values. In this case, the matrix A represents the transformation, and the column space of matrix A represents the span of the columns of A. The column space of matrix A is the set of all possible linear combinations of the columns of A.

To prove that the range of the linear transformation t(x) = Ax is equal to the column space of matrix A, we can show that every vector in the column space of A can be obtained as an output of the transformation t(x) = Ax. Additionally, we can show that every output of the transformation t(x) = Ax belongs to the column space of A.


Therefore, it is true that the range of a linear transformation defined by the matrix transformation t(x) = Ax is equal to the column space of matrix A.

Given:

The equation is

\(3.6y+7.5x=21600\)

where, y is the number of cars and x is the number of trucks shipped.

To find:

The number of trucks that can be shipped if there are no cars.​

Solution:

We have,

\(3.6y+7.5x=21600\)

If there are no cars in the cargo ship, then y = 0 because y is the number of cars.

Putting y=0 in the given equation, we get

\(3.6(0)+7.5x=21600\)

\(0+7.5x=21600\)

\(7.5x=21600\)

Divide both sides by 7.5.

\(x=\dfrac{21600}{7.5}\)

\(x=2880\)

x is the number of trucks shipped.

Therefore, the number of trucks that can be shipped if there are no cars is 2880.

Answer:

About 9cars

Step-by-step explanation:

We need to first calculate the expenses of Alonzo

Application fee = $120

Security deposit = $950

First and last months rent at $1,140 per month = 2(1,140) = $2280

Total expenses = 120+950+2280 =

Savings = $3350

Amount he saved = $1810

Total amount of money needed = $3350-$1810 = $1540

If sells 1 car for $175

x car will cost $1540

Cross multiply

175x = 1540 ×1

x = 1540/175

x = 8.8

x ≈ 9

Hence he must detail about 9 cars to have enough money to rent the apartment.

The position value, r(t) is equals to the (t³/6)k + 2j and velocity value, v(t) is equals to ( t²/2 )k + 4i , for a(t) = tk, v(0) = 4i, r(0) = 2j.

Acceleration is defined as the rate of change of the velocity of an object with respect to time. Accelerations are vector quanty.

a = dv/dt

We have the following informations are available,

Initial velocity, v(0) = 4i

Initial position, r(0) = 2j

Acceleration at any time "t",

a(t) = tk

we have to determine the value of v(t) and r(t).

As we know, a(t) = dv(t)/dt = tk

integrating the above equation ,

v(t) = ∫tk dt = ( t²/2 )k + c

at t = 0 , v(0) = 0 + c = 4i ( since, v(0) = 4i

=> c = 4i

So, v(t) = ( t²/2 )k + 4i

Also, velocity is calculated by derivative of postion (r) with respect to time.

=> v(t) = dr(t) /dt

=> r(t) = ∫ v(t) dt

=> r(t) = ∫ ( t²/2 )k dt

integrating value of the right hand side,

r(t) = ( t³/2×3 )k +d

= (t³/6)k + d

At t = 0, r(0) = (0/6)k + d

=> r(0) = d = 2j

so, r(t) = (t³/6)k + 2j

Hence, the required position and velocity are

(t³/6)k + 2j and ( t²/2 )k + 4i.

Step-by-step explanation:

To find the X value corresponding to z = -0.25, we can use the formula:

z = (X - M) / s

where z is the standardized score, X is the raw score we want to find, M is the population mean, and s is the population standard deviation.

Rearranging this formula, we get:

X = z * s + M

Substituting the given values, we get:

X = -0.25 * 12 + 50

X = 47

Therefore, the X value corresponding to z = -0.25 is 47.

Hence, the answer is option B.

The X value corresponding to z = -0.25 is 47 (option b).

To answer this question, we need to use the formula for calculating z-scores, which is:
z = (X - M) / (s)
where z is the z-score, X is the raw score, M is the population mean, and s is the population standard deviation.
In this case, we are given the population mean (M = 50) and the z-score (z = -0.25). We also know that the population standard deviation (s) is 12.
We can rearrange the formula to solve for X:
X = z * s + M
Plugging in the values we have:
X = -0.25 * 12 + 50
X = 47
Therefore, the X value corresponding to z = -0.25 is 47. The answer is (b).
It's important to note that z-scores are a way of standardizing data so that we can compare different sets of data that may have different scales or units. In this case, we are using the z-score to find the corresponding raw score.

Your answer is option b)

The time at which a star rises shifts approximately 4 minutes earlier each day, due to Earth's orbit around the Sun. Since there are roughly 30 days in a month, we can calculate the change in the rise time of Aldebaran over the course of a month.

Step 1: Calculate the time change over one month
30 days * 4 minutes per day = 120 minutes

Step 2: Convert minutes to hours
120 minutes ÷ 60 minutes per hour = 2 hours

Step 3: Subtract the time change from the current rise time
2:00 am - 2 hours = 12:00 am (midnight)

Therefore, you can expect Aldebaran to rise next month at midnight. The correct answer is b) midnight.

It will take approximately 131 months for the value of the building to reach $416,200.

To find the number of months it will take for the value of the building to reach $416,200, we need to set up an equation using the given information.

The equation for the value of the building, y, after x months of use is given as:

y = 652,000 - 1800x

We can set this equation equal to $416,200 and solve for x:

416,200 = 652,000 - 1800x

To isolate x, we can subtract 652,000 from both sides of the equation:

416,200 - 652,000 = -1800x

-235,800 = -1800x

Now, divide both sides of the equation by -1800:

-235,800 / -1800 = x

x ≈ 131

Therefore, it will take approximately 131 months for the value of the building to reach $416,200.

Thus, beginning with a 1 = 5, the formula a n = a n-1 + 7 can be used to recursively find the nth term of the sequence.

A sequence in mathematics is an ordered collection of numbers that is typically defined by a formula or rule. Every number in the series is referred to as a term, and its location within the sequence is referred to as its index. Depending on whether the list of terms stops or continues indefinitely, sequences can either be finite or infinite. By their patterns or uniformity, sequences can be categorised, and the study of sequences is crucial to many areas of mathematics, such as calculus, number theory, and combinatorics. Mathematical, geometrical, and Fibonacci sequences are a few examples of popular sequence types.

given

The sequence's terms are all different by 7 (i.e., 12 - 5 = 19 - 12 = 26 - 19 =... = 7).

The following is a definition of a recursive formula for the nth element of the sequence:

a 1 = 5 (the first term of the series is 5) (the first term of the sequence is 5)

For n > 1, each term is derived by adding 7 to the preceding term, so a n = a n-1 + 7.

Thus, beginning with a 1 = 5, the formula a n = a n-1 + 7 can be used to recursively find the nth term of the sequence. For instance, we have

a_2 = a_1 + 7 = 5 + 7 = 12

a_3 = a_2 + 7 = 12 + 7 = 19

a_4 = a_3 + 7 = 19 + 7 = 26
