Answer: -125p12z18u3
Reason:
Square negative five twice, so: -5 x -5 x -5 = -125
The first squaring is -5 x -5, which is 25. The second squaring is 25 x (-5), which is - 125.
When it comes to the letters, they act like they are being multiplied.
(p4)3 = p12
(z6)3 = z18
(u)3 = u3
So the answer is -125p12z18u3.
Hope this helps! :)
First you have to know the "power rule." This is when there is an exponent outside the parentheses and some/all of the variables/numbers in the parentheses have exponents as well. What you do is multiply the outer exponent with each of the exponents inside the parentheses.

[tex](-5)^{3}p^{12}z^{18}u^{3}[/tex]

Consider the function f(x)=x^2−6x−2 . Which equation shows function f written in vertex form? f(x)=(x−3)^2−5 f(x)=(x+3)^2−11 f(x)=(x+3)^2−5 f(x)=(x−3)^2−11
Answers
Answer:
f(x) = (x − 3)² − 11
Step-by-step explanation:
To convert to vertex form, complete the square.
f(x) = x² − 6x − 2
f(x) = x² − 6x + 9 − 9 − 2
f(x) = (x − 3)² − 11
We need to complete the square: if we add and subtract 11 from the expression, we have
[tex]f(x)=x^2-6x-2=x^2-6x-2+11-11=x^2-6x+9-11=(x-3)^2+11[/tex]
Rewrite 4x = y +6 in slope-intercept form.
Answers
Answer:
y = 4x - 6.
Step-by-step explanation:
Slope-intercept form is y = mx + c where m = the slope and c = the y-intercept.
4x = y +6
Subtract 6 from both sides:
4x - 6 = y
we would write it as y = 4x - 6.
Answer:
Slope intercept form
y = 4x - 6
Step-by-step explanation:
Slope intercept form y = mx + b
In this case 4x = y +6
Re-write
y + 6 = 4x
Subtract 6 from both sides
y = 4x - 6 <-------Slope intercept form
The population of Oak Forest is increasing at a rate of 2% per year. If the population is 53,768 today, what will it be in three years?
Answers
Answer:
56,994
Step-by-step explanation: multiply the population by 0.02, round it to the nearest whole number, and then multiply that number by 3 and add it onto 53,768
The population of Oak Forest in three years will be approximately 57,091.
Explanation:To find the population of Oak Forest in three years, we can use the formula for exponential growth. The formula is: P = P0 * (1 + r)t, where P is the final population, P0 is the initial population, r is the growth rate, and t is the number of years. In this case, P0 is 53,768, r is 0.02 (2% as a decimal), and t is 3. Plugging these values into the formula, we get:
P = 53,768 * (1 + 0.02)3
Simplifying the expression inside the parentheses:
P = 53,768 * (1.02)3
Calculating (1.02)3:
P = 53,768 * 1.0604
Calculating the final population:
P ≈ 57,091
Therefore, the population of Oak Forest in three years will be approximately 57,091.

y = |x| - 1
y = |x + 1|
y = |x - 1|
Answers
Answer: Third option
[tex]y = |x + 1|[/tex]
Step-by-step explanation:
The main function
[tex]f (x) = | x |[/tex]
has its vertex in the point (0, 0)
The function shown in the graph has its vertex in the point (-1, 0)
The transformation made to f (x) that moves its vertex one unit to the left is:
[tex]y = f (x + 1)[/tex]
After this transformation the new function is:
[tex]f (x) = | x + 1 |[/tex] Note that this function corresponds to the function plotted in the image.

John ran the 100-m dash with a time of 9.87sec. If this pace could be maintained for an entire 26-mi marathon, what would his time be? (Notice that 1 m ≈ 3.281 ft and 1 mi = 5280 ft.)
Hr____
Minutes____
Seconds____
Answers
Answer:
1 hour
8 min
49 sec
Step-by-step explanation:
we know that
1 m=3.281 ft
1 mi=5,280 ft
Convert 26 mi to ft
26 mi=26*5,280=137,280 ft
Convert 137,280 ft to m
137,280 ft=137,280/3.281=41,840.90 m
using proportion
9.87/100=x/41,840.90
x=41,840.90*(9.87)/100
x=4,129.70 sec
Remember that
1 hour=3,600 sec
1 hour=60 min
1 min=60 sec
4,129.70 sec=4,129.70/3,600= 1.147 h
0.147*60=8.82 min
0.82*60=49 sec
therefore
1 hour
8 min
49 sec
John could maintain his 100-m dash pace for an entire 26-mi marathon, his time would be 1 hour, 8 minutes, and approximately 50 seconds.
First, we need to convert John's 100-meter dash time into a pace that can be extrapolated over the marathon distance. Given that John ran a 100-m dash in 9.87 seconds, we need to find out how many meters he runs per second. This would be 100 m / 9.87 s = 10.13 meters per second.
Next, we convert the marathon distance from miles to meters. As there are 5280 feet in a mile and 3.281 feet in a meter, there are 5280 / 3.281 = 1609.34 meters in a mile. The marathon distance is therefore 26 miles * 1609.34 meters/mile = 41842.84 meters.
Using John's pace, we can calculate the time it would take to run the marathon: 41842.84 meters / (10.13 meters/second) = 4129.64 seconds.
Finally, we convert the total seconds to hours, minutes, and seconds. There are 3600 seconds in an hour and 60 seconds in a minute:
Hours: 4129.64 sec / 3600 sec/hr = 1.147 hours (1 hour)Minutes: (4129.64 sec - 1 hour × 3600 sec) / 60 sec/min = 8.827 minutes (8 minutes)Seconds: 4129.64 sec - 1 hour × 3600 sec - 8 minutes × 60 sec = 49.64 seconds (approximately 50 seconds)Therefore, if John could maintain his 100-m dash pace for an entire 26-mi marathon, his time would be 1 hour, 8 minutes, and approximately 50 seconds.

Answer:
f(6) = 2
Step-by-step explanation:
Since y is a function of x, that is y = f(x), f(6) implies that we shall be evaluating the value of y when the value of x is 6.
To do this we shall draw a vertical line, x = 6 and check where this line intersects with the graph of the function f(x)
The vertical line x = 6 intersects with the graph of the function f(x) on the horizontal line y = 2. The function f(x) assumes the value 2 for values of x between 4 and 8. Therefore, f(6) = 2
Answer: Last option.
Step-by-step explanation:
We know that input values of a function are the values of the variable "x" and output values of a function are the values of the variable "y".
By definition, in functions each input value have one and only one output value.
Then, find [tex]f(6)[/tex] you can see that the input value is [tex]x=6[/tex] and you need to find the corresponding ouput value (or "y")
You can observe in the figure attached that the value of "y" for [tex]x=6[/tex] is [tex]y=w[/tex], obtaining the point (6,2)
Therefore:
[tex]f(6)=2[/tex]

Answers
Answer:
(1,9),(3,7),(5,5) (7,2)
Answer with explanation:
The sum of two distinct variables is 10.
x + y=10
It is linear equation in two variables.
To plot this graph in two dimensional plane find two distinct points satisfying the equation.
x=0, gives , y=10 or , y=0 gives , x=10.
x=1, gives ,y=10 -1,→y=9
So,two ordered pairs lying in the coordinate system are , (0, 10) and (1, 9) or (10,0) and (1,9), you will get the equation of line.
Otherwise , you can Draw the graph of this function by writing the equation in Slope Intercept form which is as:
[tex]\frac{x}{10}+\frac{y}{10}=1[/tex]
By writing the slope intercept form of line shows that , the line passes through , (10,0) and (0,10) means cutting x axis and y axis at these two points.

B. a negatively skewed distribution
C. a positively skewed distribution
D. none of the choices are correct
Answers
Answer:
Negatively skewed.
Step-by-step explanation:
In a negatively skewed distribution, the mode is greater then the median, and the median is greater then the mean. Overall, the majority of the data is to the right, which means that the distribution of data is skewed to the left, or negatively skewed.
Answer: Hence, Option 'C' is correct.
Step-by-step explanation:
As we know that if one tail is longer than the other, the distribution is said to be skewed.
And there are two types of skewed distribution :
1) Negatively skewed
2) Positively skewed
It depends on the direction of the long tail.
If the long tail is to the right , then it is said to be positively skewed distribution.
If the long tail is to the left , then it is said to be negatively skewed distribution.
According to question, the distribution here is a positively skewed distribution.
Hence, Option 'C' is correct.
