The two inequalities have all the solutions larger than 4 in common.

To check this, we just need to solve both inequalities:

The first one is:

-2(c - 4) ≤ -4

-2c + 4 ≤ -4

4 + 4 ≤ 2c

8/2 ≤ c

4 ≤ c

The second one gives:

(1/2)d - 6 > -4

Solving it for d:

(1/2)d > -4 + 6

d > 2*2

d > 4

Then the solutions are:

c ≥ 4

d > 4

The inequalities have almost all the solutions in common, except for c = 4 which is a solution for the first one but not for the second one.

The strategy to solve the problem is to select one stack from the near doubles and count them with the doubles. Hence when the 3rd stack is counted with the first two double, 8+6 = 14. This is an addition problem.

Addition is simply counting items, number, persons, objects together to that you are no longer looking that their individual numeric value but the numeric sum of the collective whole.

Hence, when we count the first doubles we had 8

counting the penultimate stack, we have 6. Counting 8 and 6 together gives us 14.

The logarithmic expression for the given equation is ln(8th root e^5) = 5/8.

To evaluate ln(8th root [tex]e^5[/tex]) without a calculator, we first use the fact that the 8th root of  [tex]e^5[/tex] is equivalent to raising  [tex]e^5[/tex] to the 1/8 power. So, we can rewrite ln(8th root  [tex]e^5[/tex]) as ln([tex]e^{(5/8)[/tex]).

We know that e is the base of the natural logarithm, so ln(e) = 1.

We can rewrite the expression as:

ln(8th root  [tex]e^5[/tex]) = ln([tex]e^{(5/8)[/tex])

Using the property of logarithms that ln([tex]a^b[/tex]) = b ln(a), we get:

ln([tex]e^{(5/8)[/tex]) = (5/8) ln(e)

Since ln(e) = 1, we have:

(5/8) ln(e) = 5/8

Therefore,the equation ln(8th root  [tex]e^5[/tex]) = 5/8.

The graph of the new function will be a line that is steeper than the original line and slopes upward from left to right.

Since, A slope of a line is the change in y coordinate with respect to the change in x coordinate.

The net change in y-coordinate is represented by Δy and the net change in x-coordinate is represented by Δx.

Hence, the change in y-coordinate with respect to the change in x-coordinate is given by,

m = change in y/change in x = Δy/Δx

Where “m” is the slope of a line.

The slope of the function y = -3.5x + 12.8 is -3.5. If the slope is changed to 1.5, the graph of the new function will be steeper than the original function.

When the slope of a linear function is positive, the line slopes upward from left to right. When the slope is negative, the line slopes downward from left to right. The greater the absolute value of the slope, the steeper the line.

Since the new slope is positive and greater than 1, the graph of the new function will be a line that is steeper than the original line and slopes upward from left to right.

The values of x for the right triangle are x = 6 or x = -14

The perpendicular height of the right triangle divides the triangle in two triangles with the same proportions as the original triangle.

x/(2√21) = (2√21)/(x + 8) {opposite/adjacent}

x(x + 8) = (2√21)² {cross multiplication}

x² + 8x = 84

x² + 8x - 84 = 0

by factorization;

x² + 14x - 6x - 84 = 0

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

x = 6 or x = 14

Therefore, the values of x for the right triangle are x = 6 or x = -14

Answer:To find ordered pairs on the graph of the function, we can substitute different values of x in the given function and calculate the corresponding values of f(x).

Step-by-step explanation:

Here are four examples:

When x = 2, f(x) = 6/(2+1) = 2. So the ordered pair is (2, 2).

When x = -3, f(x) = 6/(-3+1) = -3. So the ordered pair is (-3, -3).

When x = 0, f(x) is undefined because we cannot divide by zero. So there is no ordered pair on the graph for x=0.

When x = 4, f(x) = 6/(4+1) = 6/5. So the ordered pair is (4, 6/5) or (4, 1.2) rounded to one decimal place.

Therefore, four ordered pairs on the graph of the function f(x) = 6/(x+1) are (2, 2), (-3, -3), (4, 1.2), and any value x ≠ 0 would have a corresponding ordered pair.

To solve the equation 7(x + 3) = 7(x + 5), we can start by simplifying both sides of the equation:

7x + 21 = 7x + 35

Subtracting 7x from both sides, we get:

21 = 35

This is a contradiction, as 21 is not equal to 35. Therefore, the equation has no solution.

However, the problem states that the equation has an infinite number of solutions. This can only happen if the missing number is a factor that appears on both sides of the equation, and therefore cancels out when we simplify the equation.

Looking at the equation, we can see that both sides have a factor of 7, which cancels out when we simplify the equation. Therefore, the missing number must be the factor that was torn off, which is 7 multiplied by the difference between the two numbers inside the parentheses:

7(5 - 3) = 14

Therefore, the missing number is 14, which corresponds to answer option B.

Answer:

(a) First, we need to find f(9+h) and f(9):

f(9+h) = (9+h)^2 + 3 = 81 + 18h + h^2 + 3 = h^2 + 18h + 84

f(9) = 9^2 + 3 = 84

Now, we can substitute these values into the difference quotient and simplify:

(f(9+h) - f(9))/h = ((h^2 + 18h + 84) - 84)/h = (h^2 + 18h)/h = h + 18

(b) Using the limit definition of the derivative:

f′(9) = lim(h→0) (f(9+h) - f(9))/h = lim(h→0) (h + 18) = 18

(c) The equation of the tangent line to the curve at the point (9,f(9)) is given by:

y - f(9) = f′(9)(x - 9)

Substituting f(9) and f′(9) into this equation, we get:

y - 84 = 18(x - 9)

y = 18x - 54 + 84

y = 18x + 30

After dilatation around T with scale factor k, the coordinates of S are (4 + 3k, -3 + 12k).

Let the scale factor be k. To find the coordinates of S after dilation about point T with scale factor k, use the following formula:

S' = T + k(S - T)

where S' is the image of S after dilation.

Plugging in the values:

S' = (4, -3) + k[(7, 9) - (4, -3)]

S' = (4, -3) + k(3, 12)

S' = (4 + 3k, -3 + 12k)

Answer:

Let the length of the rectangle be L. Then we can use the formula for the area of a rectangle:

Area = Length x Width

Substituting the given values, we get:

16 1/3 = L x 4 2/3

To solve for L, we can first convert the mixed numbers to improper fractions:

16 1/3 = 49/3

4 2/3 = 14/3

Substituting these values, we get:

49/3 = L x 14/3

To solve for L, we can multiply both sides by the reciprocal of 14/3:

49/3 ÷ 14/3 = L

Simplifying, we get:

L = 49/3 x 3/14

L = 7/1

L = 7

Therefore, the length of the rectangle is 7 inches.

y+600 = 4/5(x+900)            > this is point slope form

You can simplify to y=mx+b  slope-intercept, not sure which form they want.

The given expression represents the present value of a series of future cash flows discounted at a rate of 6.5% per year.

Each term in the expression represents a cash flow at a specific time in the future, and the denominator in each term represents the discount factor, which reflects the time value of money.

The first term, $250,000 / (1+0.065)^1, represents a cash flow of $250,000 that will be received in one year.

To determine its present value, we divide it by the discount factor (1+0.065)^1, which reflects the fact that the money will be received one year from now and is, therefore, less valuable than money received today.

Similarly, the second term, $37,500 / (1+0.065)², represents a cash flow of $37,500 that will be received in two years.

To determine its present value, we divide it by the discount factor (1+0.065)²,

which reflects the fact that the money will be received two years from now and is, therefore, less valuable than money received today.

This process is repeated for each term in the expression, representing cash flows that will be received in three, four, five, and six years, respectively.

The sum of these present values represents the total present value of the cash flows or the amount that they are worth today if they are discounted at a rate of 6.5% per year.

The requried, probability that both the first digit in the last digit of the three-digit number is even numbers is 20%.

To count the number of three-digit numbers with distinct digits that can be formed using the digits 1, 2, 3, 5, 8, and 9, we can use the permutation formula:

P(n, r) = n! / (n-r)!

In this case, we have n = 6 (since we have 6 digits to choose from) and r = 3 (since we want to form three-digit numbers). Using the formula, we get:

P(6, 3) = 120

We can choose the first digit in two ways (2 or 8), and we can choose the last digit in three ways (2, 8, or 6). For the middle digit, we have four digits left to choose from (1, 3, 5, or 9), since we cannot repeat digits. Therefore, the number of three-digit numbers with distinct digits that have an even first and last digit is:

2 x 4 x 3 = 24

The total number of three-digit numbers with distinct digits is 120, so the probability that a randomly chosen three-digit number with distinct digits has an even first and last digit is:

24/120 = 0.2 or 20%
