g(x) = -2√x + 8 is the function that has the same range as f(x) = -2√(x - 3) + 8. Both functions have the range of y ≤ 8

The function that has the same range as f(x) = -2√(x - 3) + 8 is g(x) = -2√x + 8. Both functions have the range of y ≤ 8.There are a few steps involved in determining which function has the same range as f(x) = -2√(x - 3) + 8. The range of a function refers to all the possible output values that the function can produce.Let's begin by examining the original function:f(x) = -2√(x - 3) + 8The square root symbol (√) implies that x-3 must be greater than or equal to 0. If x-3 is negative, then the function would produce an imaginary result.

Let's solve for x when f(x) = 0:0 = -2√(x - 3) + 8-8 = -2√(x - 3)4 = √(x - 3)16 = x - 3x = 19This tells us that the x-value that produces an output of 0 is x = 19. To determine the range, we need to find the maximum and minimum output values. We can use a graphing calculator or sketch a graph to determine the shape of the function and the range.The shape of the function suggests that the range is y ≤ 8, which means that the maximum value of the function is 8. This tells us that any function with the same maximum output value of 8 will have the same range as f(x).

There are 420 arrangements for seven-digit numbers that can be formed with the digits of 2201213 by permutation.

The term permutation is simply the process of arrangement or selection of objects. It involves each of several possible ways in which a set or number of things can be ordered or arranged.

We can apply the formula for permutation;

\(p(n,r) = \frac{n!}{(n - r)!}\)

where n = total number of object and r = number of objects selected.

Total number of digits = 7

number of the digit 2 = 3

number of the digit 1 = 2

number of the digit 0 = 1

number of the digit 3 = 1

so the permutation for the digits 2201213 is calculated as;

7!/(3! × 2! × 1! × 1!)

(7 × 6 × 5 × 4 × 3!)/(2 × 3!) {cancel out 3! with 3! and 4 with 2}

7 × 6 × 5 × 2

420 arrangements

Hence, by permutation, we can say that there are 420 arrangement for which seven-digit numbers can be formed with the digits of 2201213

Answer:

68 degrees.

Step-by-step explanation:

Angle A is congruent to C, or they are the same. Angles B and D would also be congruent because they are facing each other.

We are given:Distance covered by the fastest man in 9 seconds = 100m

To Find: The distance covered in 1 min 2 seconds or 62 seconds

Finding the Speed of the man:

We know that:

speed = distance covered / time taken

Speed = 100 / 9          (we are given that he travels 100 m in 9 seconds)

Speed = 11.11 m/s

Distance travelled in 62 seconds:

We know that:

distance covered = speed * time

replacing the value of speed and time

Distance = 11.11 * 62

Distance = 688.82 m

Step-by-step explanation:

Y-intercept is where the line touches the y-axis, in this case it was the origin (0,0) so the y-intercept is 0

The statement that is true about the function is:

A function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given:

The minimum value of the curve = (1.9, -5.7),

The maximum value = (0, 2)

The point the function crosses the x-axis (the x-intercept) = (-0.7, 0), (0.76, 0), and (2.5, 0)

The point the function crosses the y-axis (the y-intercept) = (0, 2)

The given points can be plotted using MS Excel, from which we have:

F(x) is less than 0 over the interval from x = -∞, to x = -0.7, and the interval from x = 0.76 to x = 2.5.

Hence, the correct option is A.

y=2/3x -3

Answer: A) the distribution of values taken by the statistic in all possible samples of the same size from the same population.

Answer:

Solution: (0, 4)

Step-by-step explanation:

Equation 1: x - 3y = -12

Equation 2:  4x + y = 4

Transform both equations into slope-intercept form

Equation 1:  x - 3y = -12

x - 3y - x = - x -12  

- 3y = -x - 12

Divide both sides by -3:

y= 1/3x + 4

slope (m) = 1/3

y -intercept is (0, 4)

Equation 2:  4x + y = 4

Subtract 4x on both sides:

4x + y - 4x = -4x + 4  

y = -4x + 4

Slope (m) = -4

y - intercept = (0, 4)

Since both equations have the same y-intercept, then it means that the value of x = 0 and y = 4 will satisfy both equations.  

Therefore, the solution is (0, 4).

To graph both equations, start at point (0, 4). Then use the slopes of each equation to plot other points and create lines for each given equation. Hope this helps.

Answer:

17 and -7

Step-by-step explanation:

5 - 17 is -12.

5 - (-7) is 12.

Since we are looking at the absolute value, the sign doesn't matter.

Answer:

The equation that can be used to solve for m∠1 is:

m∠1 = One-half(a – b)

This is because angle 1 intercepts arc a, which has a measure of a. By the same token, angle 2 intercepts arc b, which has a measure of b. The sum of the measures of angles 1 and 2 is equal to the measure of the angle formed by the two intersecting chords, which is one-half the sum of the measures of arcs a and b. Therefore, we have:

m∠1 + m∠2 = One-half(a + b)

Since m∠2 is not given, we cannot solve for m∠1 using this equation. However, we can use the fact that the sum of the measures of the angles in a triangle is 180 degrees to get:

m∠1 + m∠2 + m∠3 = 180

where m∠3 is the measure of the angle formed by the two chords outside the circle. Since this angle is supplementary to angle 1, we have:

m∠1 + m∠3 = 180

Substituting the equation for the sum of the measures of angles 1 and 2, we get:

m∠1 + One-half(a + b) = 180

Solving for m∠1, we get:

m∠1 = 180 - One-half(a + b) = One-half(360 - a - b) = One-half(a - b)

One possible equation that represents the function is:

y = 2x, which can also be written as y = 2 * x.

Here's how the function values correspond to the equation:

When x = 1, y = 2 * 1 = 2

When x = 2, y = 2 * 2 = 4

When x = 3, y = 2 * 3 = 6

When x = 5, y = 2 * 5 = 10

And so on.

Note that there are other equations that could also represent the same function, but y = 2x is one possible option.

Answer:

is there a picture I can see

The property you are referring to is called the associative property of multiplication. According to this property, when multiplying three numbers, the grouping of the numbers does not affect the result. In other words, you can change the grouping of the factors without changing the product.

In the equation you provided: 3x(5x7) = (3x5)7

The associative property allows us to group the factors in different ways without changing the result. So, whether we multiply 5 and 7 first, or multiply 3 and 5 first, the final product will be the same.
