Step-by-step explanation:

The mean is all of the numbers added together and divided by how many numbers you have

4+5+6+7+8= 30

You have five numbers that go into that thirty so divide thirty by five.

30÷5= 6

It’s simple to find mean you need to add up all the numbers then divide by how many numbers there are. So 4+5+6+7+8= 30/ 5 =6 so 6 is your answer.

Answer:

[tex]x=25.24[/tex]

Step-by-step explanation:

To find the value of [tex]x[/tex], we are solving the exponential equation [tex]-6.2^{0.1x} =-100[/tex] using logarithms.

Let's solve it step-by-step

Step 1. Divide both sides of the equation by -1 to get rid of the negative signs:

[tex]-6.2^{0.1x} =-100[/tex]

[tex]\frac{-6.2^{0.1x}}{-1} =\frac{-100}{-1}[/tex]

[tex]6.2^{0.1x} =100[/tex]

Step 2. Take natural logarithm to bot sides of the equation:

[tex]ln(6.2^{0.1x)}=ln(100)[/tex]

Step 3. Use the power rule for logarithms: [tex]ln(a^{x} )=xln(a)[/tex]

For our equation: [tex]a=6.2[/tex] and [tex]x=0.1x[/tex]

[tex]ln(6.2^{0.1x)}=ln(100)[/tex]

[tex]0.1xln(6.2)=ln(100)[/tex]

Step 4. Divide both sides of the equation by [tex]0.1ln(6.2)[/tex]

[tex]0.1xln(6.2)=ln(100)[/tex]

[tex]\frac{0.1xln(6.2)}{0.1ln(6.2)} =\frac{ln(100)}{0.1ln(6.2)}[/tex]

[tex]x=\frac{ln(100)}{0.1ln(6.2)}[/tex]

[tex]x=25.24[/tex]

We can conclude that the value of x in our exponential equation is approximately 25.24.

Using the provided radioactive decay formula and the half-life information for Silicon-32, we can predict there will be approximately 21.978 grams of Silicon-32 remaining after a 300 year period.

The question refers to the concept of half-life in physics, particularly in relation to radioactive substances. In this case, we're dealing with silicon-32, which has a half-life of 710 years. This means in 710 years, half of the silicon-32 will have decayed.

Given that the half-life of silicon-32 is 710 years, and we're examining a span of 300 years, let's use the decay formula A(t)=A0e^(ln(0.5)/T)t . Here, A0 is the initial quantity of the substance (30 grams in this case), T is the half-life (710 years), and t is the time elapsed (300 years).

Plugging these values into the formula gives us:

A(300) = 30e^(ln(0.5)/710)*300

Calculating this, we find that the amount of Silicon-32 remaining after 300 years would be approximately 21.978 grams, rounded to three decimal places.

Step-by-step explanation:

Midpoint formula=(x1+x2/2, y1+y2/2)

So...

(3+-7/2, -5+2/2) =

(-2, -3/2)

Answer:

[tex](-2, -1.5)[/tex]

x-coordinate:-2

y-coordinate:-1.5

Step-by-step explanation:

You need to use this formula to find the coordinates of the midpoint:

[tex]M=(\frac{x_A+x_B}{2},\frac{y_A+y_B}{2})[/tex]

In this case, given the points  (3, -5) and (-7, 2), you can identify that:

[tex]x_A=3\\x_B=-7\\y_A=-5\\y_B=2[/tex]

Therefore, you need to substitute these values into the formula  [tex]M=(\frac{x_A+x_B}{2},\frac{y_A+y_B}{2})[/tex]. Then you get that the coordinates of this midpoint are:

[tex]M=(\frac{3+(-7)}{2},\frac{-5+2}{2})[/tex]

[tex]M=(\frac{3-7}{2},\frac{-5+2}{2})[/tex]

[tex]M=(-2, -1.5)[/tex]

Step-by-step explanation:

3/4 - 4z +5/4 z- 1/2 + 1/2 z

Put like terms near each other

3/4- 1/2  - 4z +5/4 z+ 1/2 z

We need to get common denominators to combine

First the constant terms

3/4 - 1/2*2/2  

3/4 - 2/4 = 1/4

Then the variable terms

-4z *4/4 +5/4z + 1/2z *2/2

-16z/4 + 5/4z +2/4z

-9/4z

Changing from an improper fraction to a mixed number

Answer:

Average rate of change over the interval 2<= x <= 5:

y = 3x + 5:        3

y = 3x^2 + 1:     21

y = 3^x:             78

Step-by-step explanation:

2<= x <= 5

Average rate of change over the interval 2<= x <= 5:

y = 3x + 5

y(5) = 3(5) + 5 = 20

y(2) = 3(2) + 5 = 11

Average rate of change = (20 - 11)/(5-2) = 9/3 = 3

y = 3x^2 + 1

y(5) = 3(5^2) + 1 = 75 + 1 = 76

y(2) = 3(2^2) + 1= 13

Average rate of change = (76 - 13)/(5-2) = 63/3 = 21

y = 3^x

y(5) = 3^5 = 243

y(2) = 3^2 =9

Average rate of change = (243-9)/(5-2) = 234/3 = 78

1. Average rate of change for y = 3x + 5 over 2 <= x <= 5: 3

2. Average rate of change for y = 3x^2 + 1 over 2 <= x <= 5: 21

3. Average rate of change for y = 3^x over 2 <= x <= 5: 78

Matching:

A. Exponential function: ii. Common ratio

B. Quadratic function: iii. No common difference

C. Linear function: i. Common difference

Y-intercepts and Ranges:

1. For y = -2/5 * x + 1:

  - Y-intercept: 1

  - Range: All real numbers (-∞, ∞)

2. For y = -4x^2:

  - Y-intercept: 0

  - Range: [0, ∞)

First, let's calculate the average rate of change for the provided functions over the interval 2 <= x <= 5:

1. For y = 3x + 5:

  - Average rate of change = (f(5) - f(2)) / (5 - 2) = (3(5) + 5 - (3(2) + 5)) / (5 - 2) = (15 + 5 - 6 - 5) / 3 = 9 / 3 = 3

2. For y = 3x^2 + 1:

  - Average rate of change = (f(5) - f(2)) / (5 - 2) = (3(5)^2 + 1 - (3(2)^2 + 1)) / (5 - 2) = (3(25) + 1 - (3(4) + 1)) / 3 = (75 + 1 - 12 - 1) / 3 = 63 / 3 = 21

3. For y = 3^x:

  - Average rate of change = (f(5) - f(2)) / (5 - 2) = (3^5 - 3^2) / (5 - 2) = (243 - 9) / 3 = 234 / 3 = 78

Now, match each type of function to the term that describes its rate of change:

A. Exponential function: ii. Common ratio

B. Quadratic function: iii. No common difference

C. Linear function: i. Common difference

For the next part, we'll find the y-intercepts and ranges for the given functions:

1. For y = -2/5 * x + 1:

  - Y-intercept (where x = 0): y = -2/5 * 0 + 1 = 1

  - Range: Since the coefficient of x is negative, the function is decreasing, and it extends from negative infinity to positive infinity. The range is all real numbers.

2. For y = -4x^2:

  - Y-intercept (where x = 0): y = -4 * 0^2 = 0

  - Range: Since the coefficient of x^2 is negative, the function is concave down and reaches its maximum value at the vertex. The range is [0, ∞) because it never goes below 0.

Answer:

y = -5/8x +6

Step-by-step explanation:

First we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (7/2 -11)/(4--8)

    = (7/2 - 22/2)/(4+8)

    = (-15/2)/(12)

   = -15/24

Divide top and bottom by 3

   -5/8

Then we can use point slope form to write the equation

y-y1 = m (x-x1)

y- 11 =-5/8(x--8)

y- 11 =-5/8(x+8)

Distribute

y-11 =-5/8 x -5

Add 11 to each side

y-11 = -5/8x -5+11

y = -5/8x +6

Answer: The answer would be 44 millimeters.

Step-by-step explanation: A parallelogram has to sets of congruent sides. One set has two sides that are 9 millimeters and the other set has two sides that are 13 millimeters. 9+9 = 18, 13+13= 26 and 18+26= 44!

Final answer:

To calculate the perimeter of the parallelogram with sides of 9 millimeters and 13 millimeters, you add the lengths of opposite sides and multiply by 2. The perimeter is 44 millimeters.

Explanation:

The perimeter of a parallelogram is calculated by adding the length of all four sides. Since a parallelogram has opposite sides that are equal in length, if one side is 9 millimeters and another side is 13 millimeters, the other two sides will also be 9 millimeters and 13 millimeters respectively. The formula to find the perimeter (P) is P = 2(a + b), where a and b are the lengths of the sides.

Using this formula:

Let a = 9 mm and b = 13 mm.

Then, P = 2(9 mm + 13 mm).

P = 2 × 22 mm.

P = 44 mm.

Therefore, the perimeter of the parallelogram is 44 millimeters.

Answer:

the solution is (-6, 6)

Step-by-step explanation:

This system, y= -1/2x +3 y= -1/3x +4, can be quickly solved for x by letting y = y:

y= -1/2x +3    =   y= -1/3x +4.  Then -1/2x + 3 = -1/3x +4.  The fractional coefficients should be enclosed inside parentheses:

(-1/2)x + 3 = (-1/3)x +4

Let's remove the fractional coefficients.  The LCD is (2)(3) = 6.  Multiply all four terms by 6, obtaining:

-3x + 18 = -2x + 24

Combining like terms, we get -6 = x.  

Find y:  substitute -6 for x in either of the given equations:

y= (-1/2)(-6) +3  =  3 + 3 = 6.  So y = 6 when x = -6, and the solution is (-6, 6).

Answer:

Part 1) The measure of angle C is 90°

Part 2) The measure of angle B is 35°

Part 3) The measure of angle A is 55°

Step-by-step explanation:

we know that

The inscribed angle is half that of the arc it comprises.

step 1

Find the measure of angle C

The diameter divide the circle into two equal parts

so

If AB is a diameter

arc AB=180°

∠C=(1/2)[arc AB]

∠C=(1/2)[180°]=90°

step 2

Find the measure of angle B

arc AC=70°

∠B=(1/2)[arc AC]

∠B=(1/2)[70°]=35°

step 3

Find the measure of angle A

The sum of the internal angles of a triangle must be equal to 180 degrees

so

∠A+∠B+∠C=180°

substitute

∠A+35°+90°=180°

∠A=180°-(35°+90°)

∠A=55°

2 crusts, 1 sauce, and 2 toppings.

2 times 1 times 2 = 4.

The number of different combinations that are possible for someone who does not care for meat or white sauce is 12 combinations.

Multiplication is one of the most basic arithmetic operations, where multiplications tell us the number of ways a number is added to another.

The number of crust, sauce, and toppings that are present at the pizza shop is,

Type of crust; Thick or Thin = 2

Type of sauce; Red or White = 2

Type of toppings;  pepperoni, cheese, or vegetarian = 3

Thus, the number of different combinations that are possible for someone who does not care for meat or white sauce can be written as,

Number of combinations = 2 × 2 × 3 = 12 combinations

Hence, the number of different combinations that are possible for someone who does not care for meat or white sauce is 12 combinations.
