Answer: The answer is 36/5?
Step-by-step explanation:
The graph of f(x) = 4x3 – 13x2 + 9x + 2 is shown below.
On a coordinate plane, a function is shown. The function starts from the bottom of quadrant 3 and goes up through the x-axis at (0, negative 0.25) and then through the y-axis at (0, 2). It then starts to curve down at (0.5, 4) until it reaches (1.75, negative 0.5). It then curves up and crosses the x-axis at (2, 0) and goes up approaching x = 3.
How many roots of f(x) are rational numbers?
0
1
2
3
Answer:
3
Step-by-step explanation:
f(x) = 4x^3 – 13x^2 + 9x + 2
This looks complicated but all we need to find are the Roots
We are looking for when y=0
So given each part of the information, we can label how many times it happens
The function starts from the bottom of quadrant 3: Starts lower left
and goes up through the x-axis at (0, negative 0.25) : This is ONE ROOT
and then through the y-axis at (0, 2). : It's now on the 2nd quartile
It then starts to curve down at (0.5, 4): It's moving towards y=0
until it reaches (1.75, negative 0.5).: It has now passed y=o and there are TWO ROOTS
It then curves up and crosses the x-axis at (2, 0) and goes up approaching x = 3: It has passed y=0 again, so there are THREE ROOTS
This polynomial function has 3 ROOTS

I would think your section of wilderness will be satisfied is the new wildlife refuge has its dimensions are 5×10 to the fifth power meters by 4×10 to the 4th m find the area of land in square meters
Answer:
2×10¹⁰ m²Step-by-step explanation:
Dimensions of rectangle:
5×10⁵ m and 4×10⁴ mThe area is the product of the two dimensions:
5×10⁵ m × 4×10⁴ m =20×10₉ m² =2×10¹⁰ m²In the diagram below of triangle ABC, DE is parallel to AC. IF AD = 20, DB = 10 and AC = 33, find DE.
Answer:
11
Step-by-step explanation:
It's proportions my son.
x / 33 = 10 / 30
It's 10/ 30 because the whole BA is 30 in total
Then cross multiply.
30x = 330
x = 11

Question: +6 charge and -6 charge
Question 2: 8 units to the left of 4
(4 - 8 = -4 and 8 units left is -4)
Question 3: 4
(7 +(-3) is essentially 7-3 which equals 4 because negative takes over the positive)
Question 5: 1/-6
(it doesn't matter if the negative symbol is on top or bottom, numerator or denominator just the numbers have to stay in the same place)
Question 4: -45
(4.5 times 5 is 22.5, and 22.5 times -2 is -45, the negative takes over the positive)
Question 6: 2m-4
( 2(m-5) +6
distribute first
2 times m = 2m
2 times -5 = -10
so now you have 2m - 10 + 6
combine like terms to get 2m - 4
(-10 + 6 = -4)
Jamal and Samuel are saving for a camping trip. Jamal starts with $18 and saves $5 each week. Samuel starts with $10 and saves $7 each week. Use the drop-down menus to complete the rule for the amount of savings for each boy.
Answer:
4 weeks
$28
Step-by-step explanation:
Let
x = number of weeks
Jamal's savings = 18 + 5x
Samuel's savings = 10 + 7x
Equate both savings
Jamal's savings = Samuel's savings
18 + 5x = 10 + 7x
18 - 10 = 7x - 5x
8 = 2x
x = 8 / 2
= 4
x = 4 weeks
Check:
18 + 5x
18 + 5(2)
18 + 10
= $28
Each boy would have saved an equal amount of $28 at the end of the 4th week
1) In a bag of red and green sweets, the ratio of red sweets to green sweets is 3:7. If the bag contains 49 green sweets, how many red sweets are there?
Answer:
Red sweets = 21
Step-by-step explanation:
Let there are 3x red sweets and 7x green sweets.
Total no of 49 green sweets.
ATQ,
7x = 49
x = 7
Red sweets = 3x
= 3(7)
= 21
Hence, there are 21 red sweets.

Answer:
x=7
y=14
Step-by-step explanation:
this is a special 30-60-90 right triangle bc there is a right angle marker and a 60 degree and 30 degree angle
in 30-60-90 right triangles the short leg is x, the long leg is x√3, and the hypotenuse is 2x
it is given that the long leg is 7√3, and since the long leg equals x√3, then x equals 7
so the short leg, x, is 7 and since the hypotenuse is 2x, 2(7) =14

10/3 = x divided by -5/2
x =?
Answer:
-0.3x
Step-by-step explanation:
if you divide all of the number up you will get -0.3x
Answer:
Not possible
Step-by-step explanation:
The reason why its not possible is because to figure out a x type of problem, there needs to be a answer to it.
Lets try it solve it to make better sense.
10/3 = 3.33333333333
-5/2 = -2.5.
Divide.
= -1.33333333333.
If this is possible, the answer is -1.33333333333.
Fraction = -4/3.
A car drives 195 miles in 3 hours and 15 minuits. What is the average speed of the car?
Answer: [tex]61.9miles/hr[/tex]
Step-by-step explanation:
given data:
distance travelled by the car = 195 miles
time taken = 3 hours and 15mins
solution
average speed of the car
[tex]= \frac{195miles}{3hrs15mins} \\\\= 61.9miles/hr[/tex]
Answer:
The average speed is [tex]v=60 miles/h[/tex]
Step-by-step explanation:
The equation of the average speed os given by:
[tex]v=\frac{\Delta x}{\Delta t}[/tex] (1)
here:
Δx is just 195 miles
Δt is the time traveled. 3.25 h ( 3 h + 15 min or 0.25 h)
So we just need to put this into the equation (1)
[tex]v=\frac{195}{3.25}[/tex]
Therefore, the average speed is [tex]v=60 miles/h[/tex]
I hope it helps you!

Zoey made 6 1/2 cups of trail mix for a camping trip. She wants to divide the trail mix into 3/4 cup of servings. Twelve people are going on the camping trip. Can zoey make enough 3/4 cup servings so that each person on the trip has on serving?
Answer:
No
Step-by-step explanation:
Given that:
Total number of cups of trail mix available for camping trip = [tex]6\frac{1}{2}[/tex]
Amount of one serving contains = [tex]\frac{3}{4}[/tex] cups
Number of people at the trip = 12
To find:
Whether each person will be able to get the servings?
Solution:
Here, we can find the total number of servings by dividing the total number of cups of trail mix with the amount of one serving.
First of all, let us convert the mixed fraction into fractional number.
[tex]6\dfrac{1}{2} = \dfrac{6\times 2+1}{2} = \dfrac{13}{2}[/tex]
Therefore, total number of servings available as per the given quantities:
[tex]\dfrac{\frac{13}2}{\frac{3}4}\\\Rightarrow \dfrac{13\times 4}{2\times 3} \\\Rightarrow \dfrac{26}{3}\\\Rightarrow \approx 8[/tex]
So, With this type of servings Zoey will be able to serve only 8 people.
Therefore, there is not enough servings.

You buy pounds of trail mix. The mix costs $ per pound. What is the total price for the trail mix?
Complete question :
You buy 3.9 pounds of trail mix. The mix costs $2.99 per pound. What is the total price for the trail mix?
Answer:
$11.661
Step-by-step explanation:
Given that :
Cost per pound of trail mix = $2.99
Pounds of trail mix purchased = 3.9 pounds
Total price of the trail mix :
(Cost per pound of trail mix * pounds of trail mix purchased)
($2.99 * 3.9 pounds)
= $11.661

16. Peter was told by his teacher that he needed to measure the height of the building in which his
classroom was located. He backs away from the building and places a mirror on the ground
between him and the wall. When he can see the top of the building in the mirror, Peter is 2 feet
9 inches away from the mirror and the mirror is 11 feet away from the wall of the building. Peter
knew his eye level was exactly 5 ft 6 inches off of the ground, so he was able to calculate the
height of the building. How tall is the building in feet?

Answer:
x=-1
Step-by-step explanation:
Step 1: Subtract x from both sides.
−x+4−x=x+6−x
−2x+4=6
Step 2: Subtract 4 from both sides.
−2x+4−4=6−4
−2x=2
Step 3: Divide both sides by -2.
−2x/−2= 2/−2
x=−1

First, divide 108 by 12.
The result is 9.
Now square root 9.
The result is 3.
Now, multiply 12 by 3.
The result is 36.
To check that this is the pattern, we multiply 36 by 3, and we indeed see that 3 times 36 is equal to 108.
