Answer:
(p+13)(p+1)
Step-by-step explanation:
p² + 14p + 13
we want to find two numbers that add to 14 and multiply to 13
we can start looking by listing the factors of 13
we get 13 and 1 and -13 and -1
13 and 1 multiply to 13 ( 13 × 1 = 13 ) and add to 14 ( 13 + 1 = 14 )
-13 and -1 multiply to 13 ( -13 × -1 = 13 ) and add to -14 ( -13 + -1 = -14 )
the two numbers that would add to 14 and multiply to 13 would be 13 and 1
now we can factor out the two numbers from 14 and split the p from p² to get (p+13)(p+1)
and we are done
Find the exact location of all the relative and absolute extrema of the function. (order your answers from smallest to largest x. ) g(x) = x2 − 4 x
The minima of the quadratic function is at the vertex, it is at (2, -4).
Where are the relative minima/maxima of the function?
First, we can see that our function is a quadratic function of positive leading coefficient. So it opens upwards.
Then we will only have a minima, which is located in the vertex of the parabola.
Remember that for:
y = a*x^2 + b*x + c
The x-value of the vertex is h = -b/2a
Then for g(x) = x^2 - 4x we have:
h = -(-4)/2*1 = 2
And the y-value of the vertex is:
g(2) = 2^2 - 4*2 = -4
Meaning that the minima of the function g(x) is (2, -4).

Separate 79 into two parts such that 4 times the smaller exceeds the larger by 6.
1. Assign the variables.
2. Write the equations.
3. Solve the system.
4. Answer the question.
39 is separated into two parts 9 and 30
Step-by-step explanation:
The given is:
Separate 39 into two parts
4 times the smaller part exceeds the larger part by 6
Assume that the smaller part is x and the larger part is y
∵ 39 is separate into two parts x and y
∴ x + y = 39 ⇒ (1)
∵ x is the smaller part
∵ y is the larger part
∵ 4 times the smaller part exceeds the larger part by 6
- Multiply x by 4 and subtract y from it to get 6
∴ 4x - y = 6 ⇒ (2)
Now we have a system of equations to solve it
Add equations (1) and (2) to eliminate y
∵ (x + 4x) + (y - y) = (39 + 6)
∴ 5x = 45
- Divide both sides by 5
∴ x = 9
Substitute the value of x in equation (1) to find y
∴ 9 + y = 39
- Subtract 9 from both sides
∴ y = 30
∴ The smaller part is 9 and the larger part is 30
39 is separated into two parts 9 and 30

What is the area, in square units, of
triangle UVW?
The Area of Triangle UVW be 16 squared units.
What is Area of Triangle?The area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h.
Area of triangle I = [tex]\frac{1}{2} *b*h[/tex]
= 0.5 x 4 x 4
= 8 units
Area of triangle II= [tex]\frac{1}{2} *b*h[/tex]
= 0.5 x 2 x 6
= 6 units
Area of triangle III = [tex]\frac{1}{2} *b*h[/tex]
= 0.5 x 2 x 6
= 6 units
Area of rectangle = length x breadth
= 6 x 6
= 36units
Area of triangle UVW = Area of rectangle -(Area triangle I + Area of
triangle II +Area of triangle III)
= 36 - ( 8 + 6 + 6)
= 36 - 20
= 16 square units
Hence the Area of Triangle UVW = 16 square units.

The diameter of a circle measures 18ft what is the circumference of the circle? Use 3.14 for π and do not round
=======================================================
Work Shown:
d = diameter = 18 ft
pi = 3.14 approximately
C = circumference
C = pi*d
C = 3.14*18
C = 56.52
The distance around the circle's edge (aka perimeter) is about 56.52 feet
The result is approximate since pi = 3.14 is approximate.

Find the interquartile range (IQR) of the data in the dot plot below.
1,2,3,3,4,4,4,6
The value of interquartile range (IQR) of the data set which is plotted in the dot plot 1,2,3,3,4,4,4,6 is 1.5.
What is the interquartile range (IQR) of the data?The interquartile range (IQR) of the data is the middle half of the data, which contains 2nd and 3rd quartiles.
Interquartile range is the difference of third quartile and first quartile.
IQR=Q₃-Q₁
In the dot plot below, the data is given as,
1,2,3,3,4,4,4,6
The first quartile is the medium of the lower half, while the third quartile is the medium of the upper half. For the above data,
Q_1=2.5
Q_3=4
Thus, Interquartile range is,
IQR=Q₃-Q₁
IQR=4-2.5
IQR=1.5

List a specific example with a set and a subset.
Your example needs to be unique and in your own words.
Some examples:
The set of all animals in the world. A subset could be the group of all dogs. The set of all people in a country. A subset would be the group of people in a small town of that same country.Everything in a person's house (set), vs items located inside the person's kitchen only (subset).The set of parallelograms. A subset is the set of all squares.The set of rational numbers, in which the collection of integers is a subset.With each example, any item or person in the subset is also found in the original set (but not vice versa). For example, any dog is an animal but not the other way around.
If you were to draw a venn diagram, then the larger circle is the set of all animals, while the subset of all dogs is a smaller circle drawn completely inside the larger one.
Those examples listed above is of course not the complete list of set & subset combos. Feel free to get creative and think of others.

alex has 5 t-shirts in the drawer. 2 are white, and the rest are black. He will pick a t-shirt from the drawer without looking, and then without replacing it, will pick a second t-shirt without looking. What is the probability that he will pick a white t-shirt on his first pick and a black t-shirt on his second pick?
Answer:
24%
Step-by-step explanation:
Lets consider it.
2 are white, and 3 are black.
2/5 chance of him getting white, and 3/5 chance of him getting black
So he successfully gets white on his first try.
2/5
Then he successfully gets black on his second try
2/5 * 3/5, or 6/25, or 24% of him getting white, then black.

Find the average rate of change for the function f(x) = 2x + 4 over an interval [2, 6].
Answer:
average rate of change = 2
Step-by-step explanation:
since f(x) is a linear function, then the slope is the measure of the average rate of change of f(x).
note the average rate of change is constant over any closed interval.
the equation of a linear function in slope- intercept form is
f(x) = mx + c ( m is the slope and c the y- intercept )
f(x) = 2x + 4 ← is in slope- intercept form
with slope m = 2
then average rate of change = 2
