Use the table to describe the locations of the zeros of the quadratic function $f$ .
The zeros are between _ and_ , and between_ and_ .
Answers
Answer:
The zeros are between -4 and -3, and between 0 and 1
Step-by-step explanation:
Here, we want to location of the zeros
As we can know, at the zeros of a quadratic function, the y value at those point is zero
So whenever we have y value being zero, we have it that the x value at that point is a zero or root of the quadratic function
Now, looking at the table, we can see that between the point x = -4 and -3; y moved from -2 to 2
For this movement to occur, we must have passed through 0 as we have -1 ,0 and 1 between the numbers as -2 and 2
So obviously, the root is between -4 and -3
Secondly as we can see, f(x) moved from 2 to -2
The numbers between here are 1 , 0 and -1
So definitely the root lies between the x values of 0 and 1

Determine the point of intersection between the lines with equations x+3y=5 and 3x−2y=26.
Answers
Answer:
(8,-1)
Step-by-step explanation:
The point of intersection can be found out by solving the system of equations.
x + 3y = 5
3x - 2y = 26
Multiply (1) by 3 :-
→ 3 ( x + 3y ) = 5 × 3
→ 3x + 9y = 15
Subtracting 3(1) and 2 :-
→ 3x + 9y - 3x +2y = 15 - 26
→ 11y = -11
→ y = (-1)
Put it in 1 :-
→ x -3 = 5
→ x = 3 + 5
→ x = 8
Hence the point of intersection is (8,-1)HElp Me please i will give brainlist due in 30 MINUTES

Carlos bought 6.5 pounds of bananas for $5.20. What is the price per pound of the bananas that Carlos bought?
What quantity of bananas would one dollar buy?
Answers
Answer:
Quantity of banana purchase in $1 = 0.8 pound
Step-by-step explanation:
Given:
Cost of 6.5 pound of banana = $5.2
Find:
Price of one pound banana
Quantity of banana purchase in $1
Computation:
Price of one pound banana = 6.5 / 5.2
Price of one pound banana = $1.25
Cost of one pound banana is $1.25
Quantity of banana purchase in $1 = 1 pound / 1.25 dollar
Quantity of banana purchase in $1 = 0.8 pound

Vikram has a bucket of three different racquetballs, one blue, one black, and one red. He wants to test each ball to see how well they bounce. He reaches into the bucket and removes one ball without looking. He hits the ball against the wall, catches it, and then drops it back into the bucket. He repeats this process twice more, each time choosing a ball without looking.
Part A:
What is the probability that Vikram hits the blue ball, then the black ball, and then the red ball?
Answer:
Part B:
If Vikram does not drop the balls back into the bucket after he hits them, what is the probability that Vikram hits the blue ball, then the black ball, and then the red ball?
Answer:
Answers
Answer:
A) 33.3%
B) 50 %
Step-by-step explanation:
A) if there are 3 balls always in the bucket you need to see what one balk represent one ball is 1÷3 which is 0.33 so by knowing that if Vikram drops the ball back into the bucket after the hit there would be a 33 % chance he will chose the same or a different ball in order.
B)if he won't put the ball back in the bucket there will be only 2 balls felt so 1÷2 = 0.5 so there is a 50 % chance of Victor getting the balls in the correct order

Step-by-step explanation:
For a right triangle, a²+b²=c², where a and b are leg lengths, and c is the hypotenuse. Given one leg length and the hypotenuse, we can find the other leg length by plugging in our given information:
a²+b²=c²
12²+b²=20²
144+b²=400
b²=256
b=16
Therefore, the missing leg length is 16 units.

Step-by-step explanation:
Using the sine ratio and the exact value
sin45° = [tex]\frac{\sqrt{2} }{2}[/tex] , then
sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{30}[/tex] = [tex]\frac{\sqrt{2} }{2}[/tex] ( cross- multiply )
2x = 30[tex]\sqrt{2}[/tex] ( divide both sides by 2 )
x = 15[tex]\sqrt{2}[/tex]
The triangle is isosceles (45- 45- 90) , then 2 legs are congruent, so
y = x = 15[tex]\sqrt{2}[/tex]

A charter bus service charges a flat fee of $150, plus $3.50 per mile (one way distance) for a bus. If the band paid exactly $2050 for TWO buses, how far did the band travel?
Answers
Answer:
Number of miles= 250
Step-by-step explanation:
Giving the following information:
Fixed cost= $150
Unitary cost per mile= $3.5
Total cost= $2,050
First, we will establish the total cost formula for ONE bus:
Total cost= 150 + 3.5x
x= number of miles
For two buses:
Total cost= 150*2 + (3.5*2)x
Total cost= 300 + 7x
Replacing the total cost information:
2,050= 300 + 7x
1,750/7 = x
250 =
Number of miles= 250

Which is greater |-2| or-2
Answers
To Find :
Which is the greater |-2| or -2 .
Solution :
Value of |x| for any value of x ( real number ) is always positive .
[tex]|x| = \left \{ {x , \ for \ x >= 0 \atop { -x, \ for \ x < 0 }} \right.[/tex]
So, |-2| = 2 > -2
Therefore, the value of |-2| is greater than -2 .
Hence, this is the required solution.
