How many turns will the graph of f(x) = 3x5 -2x4 + 7x2 -9x + 8 have?
Answer:
The number of turns of graph for [tex]f(x) = 3x^5 -2x^4 + 7x^2 -9x + 8[/tex] are 4
Step-by-step explanation:
We need to find the number of turns the graph of [tex]f(x) = 3x^5 -2x^4 + 7x^2 -9x + 8[/tex] have?
Turns of graph:
The graphs turns when it changes from increasing to decreasing (rise to fall) or decreasing from increasing (fall to rise)
Turns of graph for a polynomial
A polynomial having degree n will have maximum n-1 turns.
So, for the given polynomial
[tex]f(x) = 3x^5 -2x^4 + 7x^2 -9x + 8[/tex]
We need to find degree
The highest exponent of the polynomial is the degree of polynomial
So, Degree n = 5
Number of turns = n - 1 = 5-1 =4
So, the number of turns of graph for [tex]f(x) = 3x^5 -2x^4 + 7x^2 -9x + 8[/tex] are 4

Sheryl has a Christmas lighting project. She is going
to put lights around the outside of 15 windows with
a height of 4ft and a width of 2ft. She also wants to
put lights around her 3 garage doors that are 9 feet
tall and 9 feet wide. How many feet of christmas
lights would be needed for this project?
And 288ft says it’s incorrect
Answer:
If hanging Christmas lights around the garage door is on your holiday to do list, make sure to do it right. Decorating shouldn't be a once-a-year activity that does permanent damage to your home or your body.
When it comes to hanging holiday lights around your garage door, use clips and hooks specifically designed for the task. Avoid using metal fasteners like staples or nails if you are attaching lights directly to the trim; the metal can damage the wiring and create a fire or electrocution hazard. Instead, clip the plastic fasteners to the light string and attach the plastic fasteners to your trim. This way the clips can remain throughout the year, and lights are more easy to hang in the holidays to come.
For the vertical runs, find the trim clips that wrap around the light string and hold it into place (this is particularly important for our Sioux City and Yankton breezes and blizzards). Aim for a clip every 12 inches or so. Some homeowners choose to nail the clips for stability; others use a removable adhesive.
If you are continuing to light up your house with lights around your roof and gutter lines, there are other items that can help make this process easier. Roof and gutter clips can be pressed directly onto the home's exterior; they typically have a hook at the bottom that grabs the light string. Please be very careful when working on high and precarious locations!

the sum of third and seventh terms of an AP is 20 . Find the sum of the first nine
Given:
The sum of third and seventh terms of an AP is 20.
To find:
The sum of the first nine terms.
Solution:
We have, the sum of third and seventh terms of an AP is 20.
[tex]a_3+a_7=20[/tex] ...(i)
nth term of an AP is
[tex]a_n=a+(n-1)d[/tex]
where, a is first term and d is common difference.
[tex]a_3=a+(3-1)d[/tex]
[tex]a_3=a+2d[/tex] ...(ii)
[tex]a_7=a+(7-1)d[/tex]
[tex]a_7=a+6d[/tex] ...(iii)
Using (i), (ii) and (iii), we get
[tex](a+2d)+(a+6d)=20[/tex]
[tex]2a+8d=20[/tex] ...(iv)
Now, the sum of first n terms of an AP is
[tex]S_n=\dfrac{n}{2}[2a+(n-1)d][/tex]
Put n=9 to find the sum of first 9 terms of an AP.
[tex]S_n=\dfrac{9}{2}[2a+(9-1)d][/tex]
[tex]S_n=\dfrac{9}{2}[2a+8d][/tex]
[tex]S_n=\dfrac{9}{2}[20][/tex] [Using (iv)]
[tex]S_n=\dfrac{180}{2}[/tex]
[tex]S_n=90[/tex]
Therefore, the sum of the first 9 terms is 90.
If x and y are two complementary angles,then find the value of y if measure of angle x is 20 degree
Answer:
y = 70°
Step-by-step explanation:
Complementary angles sum to 90°, then
x + y = 90°, that is
20° + y = 90° ( subtract 20° from both sides )
y = 70°

At 6 AM the temperature read -17 F by noon it had risen by 23 F. Find the new temperature
Answer:
6 F
Step-by-step explanation:
We want to find the temperature difference
Given that the initial temperature read minus 17 F
And the new temperature is increased by 23 F
The new temperature is
=-17+23= 6 F
Therefore the new temperature is 6F

= 294 cm^2
ASAP!!!! What is the answer?
Answer:
A, B, C
Step-by-step explanation:
Since the sum of the angles in a triangle is [tex]180^{\circ}[/tex], you can set the equation [tex]9x-7+7x-9+28-2x[/tex]. Simplifying gets [tex]14x=168[/tex]. Dividing gets you [tex]x = 12[/tex]. This is only x so you have to substitute 12 for x in the angles in the beginning to get [tex]\angle{A}=101^{\circ}[/tex], [tex]\\\angle{B}=75^{\circ}[/tex], [tex]\\\angle{C}=4^{\circ}[/tex]
What does the constant of proportionality represent?
a
The constant ratio of one variable quantity to another to which it is proportional (or the Unit Rate)
b
The value that says all of our ratios are equivalent
c
The number that tells us how fast something is moving
d
The relationship between two rates with no similar units
100 points please answer!!!!
Answer:
a.
Step-by-step explanation:
By definition, the constant of proportionality is a constant ratio of two variables that are proportional. So the answer is a . The constant ratio of one variable quantity to another to which it is proportional (or the Unit Rate).

1/x+2=2/x-1 identify all values of X that make the equation true
9514 1404 393
Answer:
as written: x = 1/3
as maybe intended: x = -5
Step-by-step explanation:
As written
(1/x) +2 = (2/x) -1
3 = 1/x . . . . . . . . . add 1-(1/x)
x = 1/3
__
As maybe intended
1/(x +2) = 2/(x -1)
x -1 = 2(x +2) . . . . . . . multiply by (x+2)(x-1)
x -1 = 2x +4 . . . . . . . . eliminate parentheses
-5 = x . . . . . . . . . . . . . subtract (x+4)
-. The 7th grade enrollment went from 400 to 300 students last year. What was the percent of
decrease?
=========================================
Work Shown:
A = old value = 400
B = new value = 300
C = percent change
C = [(B-A)/A]*100%
C = [(300-400)/400]*100%
C = (-100/400)*100%
C = (-0.25)*100%
C = -25%
The negative value of C means we have a percent decrease. Specifically we have a 25% decrease.
---------
We can see that by saying:
25% of 400 = 0.25*400 = 100
400 - (25% of 400) = 400 - 100 = 300

You bought a used truck for $15,000. The value of the truck will
decrease each year because of depreciation. The truck depreciates at the rate of 8% per year. Write an exponential decay model to represent the real-life problem.
Answer:
[tex]15000 \times {0.92}^{x} = y[/tex]
x is the number of years and y is the value at x years
The exponential decay model to represent the real-life problem should be considered as the [tex]15000 \times 0.92^{x} = y[/tex].
Calculation of the exponential decay model:Since the purchase value of the truck is $15,000
The depreciation rate is 8%
So here exponential decay model should be like
[tex]15000 \times 0.92^{x} = y[/tex]
Hence, The exponential decay model to represent the real-life problem should be considered as the [tex]15000 \times 0.92^{x} = y[/tex].

What slope would make the lines perpendicular? y = 4x + 2 y = -x + 2 Enter the number that belongs in the green box.
Answer:
The missing number in the green box is 4
Step-by-step explanation:
The product of the slopes of the perpendicular lines is -1, which means
if the slope of one of them is m, then the slope of the perpendicular line to it is the negative reciprocal ([tex]\frac{-1}{m}[/tex])The slope-intercept form of the linear equation is y = m x + b, where
m is the slope of the lineb is the y-interceptLet us solve the question
∵ The equation of the first line is y = 4x + 2
→ Compare it with the form of the linear equation above
∴ m = 4
∵ m is the slope
∴ The slope of the line is 4
∵ The slope of the perpendicular line should be the negative reciprocal of it
∵ The negative reciprocal of 4 is [tex]-\frac{1}{4}[/tex]
∴ The slope of the perpendicular line is [tex]-\frac{1}{4}[/tex]
→ Substitute it in the equation
∴ y = [tex]-\frac{1}{4}[/tex] x + 2
∴ The missing number in the green box is 4
A recipe for a loaf of bread calls for 2/3of a cup of flour. If Milo used 12 cups of flour, how many loaves of bread did he prepare?
Answer: 18 loaves of bread.
Step-by-step explanation:
Do 12 divided by 2/3 which is the same thing as multiplying 12 by the reciprocal (just flip the fraction) of 2/3 which is 3/2. 12x3/2 is 36/2 which is equal to 18.

find the time to ride 12 miles, so how many yards is 12 miles?
12 miles * 1760 yards / 1 mile = 21120 yds
d =r*t d=distance , r= rate , t = time
we know the distance and the rate .. so we can find the time
d/r = t
21120/6 = t ( in seconds)
3520 = t sec.
3520 sec * 1 min / 60 seconds ( to convert to minutes )
3520/60=t ( in minutes)

The factors of the given expression.
Solution:
We have,
[tex]x^3(2x-6)+x^2(2x-6)[/tex]
First taking [tex](2x-6)[/tex] common, the given expression can be written as
[tex]=(2x-6)(x^3+x^2)[/tex]
