A
The A choice is that the y intercept of g(x) < y intercept of f(x). Remember, a y intercept occurs when x = 0
g(x) = 2 * sqrt(x) - 8
g(0) = 2*0 - 8
g(0) = - 8
=======
f(x) = - 4 when x = 0 (you just read it.) - 4 is greater than -8. That's a true statement. Think money. Would you rather be 4 dollars in debt or 8 dollars in debt?
A: True <<<<<< answer for A.
B
y intercept occurs when x = 0 The values of f(x) and g(x) have been found in part A.
Are they equal?
The y intercept of g(x) = g(0) = 2*sqrt(0) - 8 = - 8
The y intercept of f(x) = f(x) = - 4 when x = 0
Conclusion
They are not equal and B is not the answer.
C
The x intercept occurs when y = 0
g(x) = 0
0 = 2*sqrt(x) - 8
8 = 2*sqrt(x)
4 = sqrt(x)
x = 16
======
When f(x) = 0, x = 16.
Conclusion
The x intercepts are both 16. This statement is true.
C: True <<<<<< answer.
D
If the condition is anything but equal, the statement is false. g(x) is not greater then f(x).
D <<<<<< False.

2,5,11,20 32,47 what is the next number in the series
Answers
+3,+6, +9,+12,+15,+18, +21,
The next number in the series is 65. To identify the pattern in the given series and find the next number, let's look at the differences between consecutive terms.
5 - 2 = 3
11 - 5 = 6
20 - 11 = 9
32 - 20 = 12
47 - 32 = 15
As we observe, the differences between consecutive terms are increasing by 3 each time. So, to find the next difference, we add 3 to the last difference:
15 + 3 = 18
Now, to find the next number in the series, we add this difference to the last number in the series:
47 + 18 = 65
Therefore, the next number in the series is 65.

The sum of two numbers is 43 . The larger number is 11 more than the smaller number. What are the numbers
Answers
b- second number
a + b = 43 (the sum of two numbers is 43)
(a +11) = b (he larger number is 11 more than the smaller number)
so:
a + b = 43
a + (a + 11) = 43
a + a + 11 = 43
2a = 43 - 11
2a = 32
a = 16
now:
a + b = 43
16 + b = 43
b = 43 - 16
b = 27
that is:
a = 16
b = 27
--------------------------
checking:
b - a = 11
27 - 16 = 11 (TRUE)

A rubber ball dropped on a hard surface takes a sequence of bounces, each one 4/5 as high as the preceding one. If this ball is dropped from a height of 10 feet, what is the total vertical distance it has traveled at the time when it hits the surface for its fifth bounce?
A) 28 77/125 feet
B) 49 1/25 feet
C) 57 29/125 feet
D) 59 29/125 feet
Answers
Answer:
The answer is 57 29/125 feet ⇒ answer (C)
Step-by-step explanation:
∵ The ball dropped from a height 10 feet
∴ The vertical distance = 10 feet
∵ It bounces 4/5 as high as the preceding one
∴ 1st bounce = 10 × 4/5 = 8 (move down another 8)
∴ The vertical distance = 8 + 8 = 16 feet
∴ 2nd bounce = 8 × 4/5 = 6.4 (move down another 6.4)
∴ The vertical distance = 6.4 + 6.4 = 12.8 feet
∴ 3rd bounce = 6.4 × 4/5 = 5.12 (move down another 5.12)
∴ The vertical distance = 5.12 + 5.12 = 10.24 feet
∴ 4th bounce = 5.12 × 4/5 = 4.096 (move down another 4.096)
∴ The vertical distance = 4.096 + 4.096 = 8.192 feet
∵ The ball will hit the surface to make the 5th bounce
∴ The total vertical distance is :
10 + 16 + 12.8 + 10.24 + 8.192 = 57.232 = 57 29/125
Another way:
* We can use the formula of geometric sequence with
1st bounce distance (a) = 8 + 8 = 16 and ratio (r) = 4/5
and number of bounces (n) = 4 (hit the surface for its 5th bounce)
∵ [tex]S_{n}=\frac{a(1-(r^{n}))}{1-r}[/tex]
∴ [tex]S_{4}=\frac{16(1-(\frac{4}{5})^{4})}{1-\frac{4}{5}}=47\frac{29}{125}[/tex]
* Then we must to add the 10 feet
(the ball dropped from height 10 feet)
∴ The total vertical distance = 10 + 47 29/125 = 57 29/125 feet

Q # 17 , Find the slope
Answers
From the above graph we can see that the points (-4,-1) and (0, -3) lie on the line. So using these two points we can find the slope.
[tex]Slope=m= \frac{-3-(-1)}{0-(-4)} \\ \\ m= \frac{-3+1}{0+4} \\ \\ m= \frac{-2}{4} \\ \\ m= \frac{-1}{2} [/tex]
So, first option is the correct answer
m = (y2-y1) / (x2-x1)
Substituting values we have:
m = (- 4 - (- 3)) / (2-0)
Rewriting we have:
m = (- 4 + 3) / (2-0)
m = (- 1) / (2)
m = -1 / 2
Answer:
The slope is given by:
m = -1 / 2

What are a) the ratio of the perimeter’s b) and the ratio of areas of the larger figure to the smaller figure?
Answers
a) We have been given two similar figures and we have to find ratio of perimeters of these figures.
Let a be given side of larger figure and b be the given side of smaller figure. Let [tex]p_{1} \text{ and } p_{2}[/tex] be the perimeters of two figures and [tex]A_{1} \text{ and } A_{2}[/tex] be the areas of the two figures.
We know that perimeters of two similar figures are in the ratio of corresponding sides.
[tex]\frac{p_{1}}{p_{2}}=\frac{a}{b}[/tex]
We have been given, [tex]a=26\text{ and }b=6[/tex]
Therefore, upon substituting these values in the above equation, we get
[tex]\frac{p_{1}}{p_{2}}=\frac{26}{6}[/tex]
[tex]\frac{p_{1}}{p_{2}}=\frac{13}{3}[/tex]
(b)
Further we know that areas of two similar figures are in the ratio of squares of corresponding sides.
[tex]\frac{A_{1}}{A_{2}}=\frac{a^{2}}{b^{2}}\\ \frac{A_{1}}{A_{2}}=\frac{26^{2}}{6^{2}}\\ \frac{A_{1}}{A_{2}}=\frac{676}{36}\\ \frac{A_{1}}{A_{2}}=\frac{169}{9}\\[/tex]

8x+6=5x+9
[tex]8x + 6 = 5x + 9[/tex]
Answers
8x - 5x = 9 - 6
Now combine like terms:
3x = 3
Divide by 3 to isolate the variable x.
x = 1
Final answer:
To solve the equation 8x + 6 = 5x + 9, subtract 5x from both sides to get 3x + 6 = 9, then subtract 6 from both sides to get 3x = 3. Finally, divide by 3 to find x = 1.
Explanation:
The equation given is 8x + 6 = 5x + 9. To solve for x, you first want to get all terms containing x on one side and the constants on the other. This is achieved through the use of addition or subtraction. From LibreTexts™, we know that addition or subtraction of the same number on both sides of an equation maintains equality. So, subtract 5x from both sides:
8x + 6 - 5x = 5x + 9 - 5x
3x + 6 = 9
Next, you subtract 6 from both sides to isolate the x term:
3x + 6 - 6 = 9 - 6
3x = 3
Now, you divide both sides by 3, a step also indicated by LibreTexts™ as multiplication or division by the same number maintains the equation's balance:
3x / 3 = 3 / 3
x = 1
The solution to the equation is x = 1.

x-4y=5
Answers
To solve this problem using substitution, we need to set x equal to a value and substitute it into the other equation.
Since
x - 4y = 5,
x = 5 + 4y
3x - 7y = 10
3(5 + 4y) - 7y = 10
15 + 12y - 7y = 10
15 + 5y = 10
5y = -5
y = -1
Now that we know y is -1, we can substitute it back into the equation to find x:
y = -1
x - 4y = 5
x - 4(-1) = 5
x - (-4) = 5
x + 4 = 5
x = 1
So, your answers are x = 1 and y = -1.

Answers
Answer:
Given is:
Out of the employees surveyed, 83% rated the vacation policy as "delightful" with a margin of error of ±2% and a confidence interval of 95%.
±2% means plus 2% from 83% and minus 2% from 83%, making the interval between 81% and 85%.
In general the margin of error tells that, how many percentage points the results will differ from the real population value. A small margin of error shows trustworthy results whereas a large margin of error means the results are not accurate.
Therefore, it can be concluded, with 95% confidence, that between 81% and 85% of all employees will rate the vacation policy as "delightful."

Hello There!
Median: The middle number when all the numbers are listed in oder from least to greatest.

The middle number would be 8 so the median for this set of numbers is 8.
suppose you toss a fair coin and roll a fair six-sided die. What is the probability your actions result in tails on the coin and 3 on the die
Answers
If you roll a fair six-sided die and a fair four-sided die, what is the probability that neither die shows a 1?
Answers
Answer in decimal form: 0.625
==============================================
Explanation:
There are 5 sides that aren't labeled "1" out of 6 total. So the probability of not rolling a "1" on the six-sided die is 5/6
Similarly, there are 3 sides that aren't labeled "1" out of 4 sides on the four-sided die. The probability of not rolling a "1" for this die is 3/4
Multiply the fractions
(5/6)*(3/4) = (5*3)/(6*4) = 15/24 = 5/8
The answer in fraction form is 5/8 which converts to 0.625 (use long division or a calculator)
Note: the multiplication of probabilities works because the two events (of rolling each die) are independent
