alfa = 2
beeta = -3
product of zeros = 2x-3= -6
sum of zeros = 2+[-3] = -1

A hiker leaves her camp in the morning. She walks 9 miles west then 10 miles north. Explain how you would find how far she has traveled from her camp.
Answers
Answer:
About 13.45 miles ( rounded )
Step-by-step explanation:
You would use the pythagorean theorem to solve this. ([tex]a^{2}[/tex]+ [tex]b^{2}[/tex] = [tex]c^{2}[/tex])
[tex]a^{2}[/tex] would be one length of that triangle, we'll use 9.
[tex]b^{2}[/tex] would be the other length of that triangle, we'll use 10.
So, now you have to square both of them.
[tex]9^{2}[/tex] = 81 ( 9 x 9 ) [tex]10^{2}[/tex] = 100 ( 10 x 10 )
Which you will get 81 and 100. Then you add those two numbers together.
100 + 81 = 181
Now that you have 181, you have to square root 181.
[tex]\sqrt{181}[/tex]
With that you should get 13.45 miles. (rounded)
In a scale drawing of a house, 1/2 inch = 1 1/2 feet. If the length of a kitchen is 5 1/2 inches on a scale drawing, what is the actual length of the kitchen?
Answers
Answer:
16 1/2 feet
Step-by-step explanation:
The above question is calculated as:
1/2 inch = 1 1/2 feet.
5 1/2 inches = x
Cross Multiply
1/2 inch × x = 5 1/2 inch × 1 1/2 feet
x = 5 1/2 inch × 1 1/2 feet/ 1/2 inch
x = 11/2 × 3/2 ÷ 1/2
x = 11/2 × 3/2 × 2/1
x = 33/2 feet
x = 16 1/2 feet
Therefore, the actual length of the kitchen is 16 1/2 feet
The stem-and-leaf plot shows the number of broken crayons in each crayon box at a preschool. What is the greatest number of broken crayons in a box? A 7 crayons B 47 crayons c 477 crayons d 1469 crayons
Answers
Answer:
47
Step-by-step explanation:
Values on a stem and leaf plot can be obtained by using the key :
Stem | leaf
With each value in the stem representing the first digit and the value in the leaf denoting the second digit.
The highest stem value here is 4 and the highest leaf value is 7.
Hence, the highest number of broken crayon is 47.

Now say you invest the $6,500 and the highest interest rate you can find is 2.5% compounded annually, but you would have to leave the investment in the account for a minimum of 5 years. If you decide to wait 5 years to buy the car, how much more money will you have to save to buy a car at the $8,000 price?
Answers
Answer:
$648.5
Step-by-step explanation:
Given data
Principal= $6,500
Rate= 2.5%
Time= 5 years
The compound interest formula is given as
A= P(1+r)^t
substitute
A= 6500(1+0.025)^5
A= 6500(1.025)^5
A=6500*1.131
A=$7351.5
After 5 years the money in the account will be $7351.5
Now to buy a car of $8,000
The added amount will be
=$8,000-$7351.5
=$648.5

(3x - 5) + 2(5x - 10) + 2(6x + 25) = 540
3x - 5 + 10x - 20 + 12x + 50 = 540
25x + 25 = 540
25x = 540 - 25
25x = 515
x = 515 / 25
x = 20.6
Answer:
[tex]\huge\boxed{\sf x = 20.6}[/tex]
Step-by-step explanation:
We know that the sum of interior angles of a pentagon is:
=> (n-2) *180
Were n is the no. of sides
=> (5-2)*180
=> 3 * 180
=> 540
Hence, The sum of interior angles of a pentagon is 540.
So,
=> 3x - 5 + 6x + 25 + 5x - 10 + 5x - 10 + 6x + 25 = 540
Combining like terms
=> 3x + 6x + 6x + 5x + 5x - 5 + 25 + 25 - 10 - 10 = 540
=> 25x + 25 = 540
=> 25x = 540 - 25
=> 25x = 515
Divide both sides by 25
=> x = 515 / 25
=> x = 20.6

A bag contains 25 red cubes, 15 green cubes, 12 blue cubes, and 8 yellow cubes. The cube is picked at random from the bag. Find each probability as a fraction is lowest terms
Answers
Answer:
25/70=red cubes
15/70=green cubes
12/70=blue cubes
8/70=yellow cubes
Step-by-step explanation:
you have to add up all the cubes together and get 70 so you have to see the possibility of getting each cube from the bag.
sorry if you get this wrong
Answer:
Step-by-step explanation: Alright so first add up how many cubes there are in total - 25 + 15 + 12+ 8 = 60. Then, each color cube is its number out of 60. So, for example, for 25 red cubes, it would be 25/60 as a fraction and that’s the probability as a fraction for the red cubes. So:
red = 25/60
green = 15/60
blue = 12/60
yellow = 8/60
then simply the fractions.
25/60 —> 5/12
15/60 —> 1/4
12/60 —> 1/5
8/60 —> 2/15

Answer:
Interes= 162,58
Step-by-step explanation:
Dada la siguiente información:
Se deposita 4000 soles a una tasa de interés del 0,8% quincenas
Primero, debemos calcular el valor final de la inversión:
VF= [VP*( 1 + i)^n]
VF= 4.000*(1,008^5)
VF= 4.162,58
Para calcular el interés ganado en 5 quincenas, debemos usar la siguiente formula:
Interes= 4.162,58 - 4.000
Interes= 162,58
