Someone please help me on the question.

Answer:

1m/s^2

Step-by-step explanation:

the formula for acceleration is change in velocity divided by time

the change in velocity is 4m/s (subtract 5 from 9)

the change in time is 4 seconds

so 4m/s ÷ 4s

this gives you 1m/s^2

Answer:

Slope = 3/7

y - intercept: y = -3

x - intercept x = 7

Step-by-step explanation:

You have to cimplify the equation in terms of y

-3x +7y= -21

7y= 3x-21

y = 3/7x - 3

SLOPE: It is whatever x is mutlipliedby

slope would be 3/7

Y intercept: you need to plug in x=0

y = 3/7(0) - 3

Zero multipled by anything is zero so you are left with

y = -3

X intercept: plug in y = 0

0 = 3/7x - 3

Move the -3 to the other side

3 = 3/7x

Multiply by the reciprocal 7/3

x = 7/3 * 3

x = 21/3

x = 7

The fantastic four in 1961

If the equation has infinitely many solutions for x, the value of b that results in infinitely many solutions for x is b = 5/2.

To determine the value of b in the equation a(x + b) = 4x + 10, we can analyze the conditions that would result in infinitely many solutions for x.

First, let's simplify the equation:

a(x + b) = 4x + 10

Expanding the left side of the equation

ax + ab = 4x + 10

Now, let's rearrange the equation to isolate x:

ax - 4x = 10 - ab

Factor out x on the left side:

x(a - 4) = 10 - ab

For the equation to have infinitely many solutions, the coefficient of x (a - 4) must be zero, because any value of x would satisfy the equation.

Therefore, we have:

a - 4 = 0

Solving for a:

a = 4

Substituting the value of a into the equation:

4 - 4 = 0

0 = 0

The equation holds true, indicating that a = 4 satisfies the condition for infinitely many solutions. Now, we can find the value of b.

Substituting a = 4 into the original equation:

4(x + b) = 4x + 10

Expanding:

4x + 4b = 4x + 10

Since the x terms cancel out, we are left with:

4b = 10

Dividing both sides by 4:

b = 10/4

Simplifying:

b = 5/2

Therefore, the value of b that results in infinitely many solutions for x is b = 5/2.

We are given a set of vectors S in M₂₂ and we need to show that S is linearly independent. We then deduce that S is a basis for M₂₂. Additionally, we are asked to express vector A as a linear combination of the vectors in S and find the coordinates of A with respect to the basis S.

To show that S is linearly independent, we need to demonstrate that the only solution to the equation c₁v₁ + c₂v₂ + c₃v₃ = 0, where c₁, c₂, and c₃ are scalars, is c₁ = c₂ = c₃ = 0. Here, v₁, v₂, and v₃ are the vectors in S.

Let's consider the vectors in S:

v₁ = {[H, 3H, H]}

v₂ = {[H², H], 24}

v₃ = {[-15, 1], 5}

To show linear independence, we set up the equation c₁v₁ + c₂v₂ + c₃v₃ = 0 and solve for c₁, c₂, and c₃.

c₁{[H, 3H, H]} + c₂{[H², H], 24} + c₃{[-15, 1], 5} = 0

By comparing the corresponding entries on both sides of the equation, we obtain the following system of equations:

c₁H + c₂H² - 15c₃ = 0

3c₁H + c₂H + c₃ = 0

c₁H + 24c₂ + 5c₃ = 0

We can solve this system of equations to find c₁, c₂, and c₃. If the only solution is c₁ = c₂ = c₃ = 0, then S is linearly independent.

To deduce that S is a basis for M₂₂, we need to show that S is linearly independent and spans the entire space M₂₂. Since we have shown linear independence, we now need to demonstrate that S spans M₂₂. To do this, we need to show that any matrix in M₂₂ can be expressed as a linear combination of the vectors in S.

Finally, to express vector A = {[-15, 1], 5} as a linear combination of the vectors in S, we solve the equation c₁v₁ + c₂v₂ + c₃v₃ = A for the coefficients c₁, c₂, and c₃. Once we find the coefficients, we can write (A)s to represent the coordinates of A with respect to the basis S.

In conclusion, to summarize the answer, we have shown that S is linearly independent, which implies that S is a basis for M₂₂. We can express vector A as a linear combination of the vectors in S and find its coordinates with respect to the basis S. However, the specific calculations to find the coefficients and coordinates are not provided in the question.

Step-by-step explanation:

A. Apparently, your (machine instructions, algebra) are ...

  (multiply by 5, 5w)

  (subtract 6, 5w-6)

  (divide by 3, (5w-6)/3)

  (add 2, (5w-6)/3 +2)

Sure, here is the formula for the perimeter of a rectangle with a length of 5 inches:

Perimeter = 2(5 + w)

where:

Perimeter is the total length of all the sides of the rectangle, in inches

5 is the length of one side of the rectangle, in inches

w is the width of the rectangle, in inches

The variable w depends on the variable 5, because the width of the rectangle cannot be greater than the length of the rectangle.

Here is an example of how to use the formula:

If the length of the rectangle is 5 inches and the width is 3 inches, then the perimeter is:

Perimeter = 2(5 + 3)

= 2(8)

Step-by-step explanation:

the A and X are equal

The range of the exponential function y based on its equation and the context of the problem is a set of positive real numbers less than the initial value of 62,150, representing the decreasing value of the car over time.

The given function represents the depreciation of Morgan's car over time, where x represents the number of months since the car was purchased. The function is y = 62,150 * (0.9999)^x.

To determine the range of the exponential function y, we need to consider the context of the problem. In this case, the range represents the possible values for the car's depreciation, or the value of y.

The base of the exponential function is 0.9999, which is less than 1. When a value between 0 and 1 is raised to a positive power, it decreases exponentially as the power increases. Therefore, as x (the number of months) increases, the value of y (the car's depreciation) decreases.

Since the base is less than 1, the range of the exponential function y is also less than the initial value of 62,150. As x approaches infinity, the value of y approaches 0, but it will never actually reach 0.

In practical terms, the range of the exponential function represents the decreasing value of the car over time. It indicates that the car's depreciation is continuous and will approach zero but will never completely reach zero.

a) To calculate the standard error of the mean number of inclusions, we divide the sample standard deviation by the square root of the sample size. In this case, the sample mean number of inclusions is 31.0635, and the sample standard deviation is 2.0996. The sample size is 30. Therefore, the standard error of the mean number of inclusions can be calculated as follows:

Standard Error = Sample Standard Deviation / √Sample Size

Standard Error = 2.0996 / √30 Standard Error ≈ 0.3836 (rounded to four decimal places) b) To estimate a 95% confidence interval for the mean number of inclusions per tourmaline gem, we can use the formula: Confidence Interval = Sample Mean ± (Critical Value × Standard Error) The critical value corresponds to a 95% confidence level, which is 1.96 for a large sample size. Using the standard error calculated in part (a) as 0.3836 and the sample mean of 31.0635, the confidence interval can be calculated as: Confidence Interval = 31.0635 ± (1.96 × 0.3836)

Confidence Interval ≈ 31.0635 ± 0.7521 Confidence Interval ≈ (30.3114, 31.8156) (rounded to four decimal places) Therefore, we can estimate with 95% confidence that the mean number of inclusions per tourmaline gem lies between approximately 30.3114 and 31.8156.

Let's call one leg of the triangle "x" and the other leg "2x-4". We can use the Pythagorean theorem to solve for the lengths of the legs:

x^2 + (2x-4)^2 = 10^2

x^2 + 4x^2 - 16x + 16 = 100

5x^2 - 16x - 84 = 0

We can solve this quadratic equation by factoring or using the quadratic formula. Factoring gives us:

(5x + 14)(x - 6) = 0

So x = -14/5 or x = 6. We can discard the negative solution since we're dealing with lengths. Therefore:

x = 6

This number does not correspond to the correct product of 243,192 multiplied by 4.

Rae's method appears to involve breaking down the numbers into their components and performing the multiplication operations separately. Let's analyze her answer:

243, 192 x 4 - 8 | 16 12 | 4 | 36 | 8 1

It seems that she broke down the number 243,192 into its individual digits (2, 4, 3, 1, 9, and 2) and performed separate calculations for each digit. However, her approach is not mathematically accurate or coherent.

Now, let's translate Rae's answer into a number that can be understood in base 10:

243,192 x 4 - 8 | 16 12 | 4 | 36 | 8 1

If we reassemble the digits without the vertical separators, we get: 8161243681.
