Answer:
(b) 1/3
Step-by-step explanation:
A function "zero" is a value of x that makes the value of the function be zero. It may also be called a "root" of the function. On a graph, it is an x-intercept.
The zeros are the solutions to the equation f(x) = 0. For a quadratic like the one given, there are two of them. For this function, they are distinct, so one will be larger than the other.
GraphThere are a number of ways the solutions to this equation can be found. Technology, in the form of a graphing calculator, can show you the x-intercepts easily (see attached). They are x=-2/5 and x=1/3.
FactoringWe can also factor the equation. Doing this requires that we find factors of the product (15)(-2) = -30 that have a sum equal to the coefficient of x, +1. Here are some factor pairs:
-30 = (-1)(30) = (-2)(15) = (-3)(10) = (-5)(6)
The corresponding sums are 29, 13, 7, 1. Hence the last factor pair, {-5, 6}, is the one we need.
Rewriting the 3-term polynomial to a 4-term polynomial by splitting the middle term using these factors, we have ...
15x² -5x +6x -2 = 0
Factoring pairs of terms gives ...
5x(3x -1) +2(3x -1) = 0
(5x +2)(3x -1) = 0 . . . . . . . factor out the common factor
The product of these factors can only be zero of one of them is zero. (This is the "zero product rule.") Setting the factors to zero, we find the values of x that make f(x) = 0: the zeros of the function.
5x +2 = 0 ⇒ x = -2/5
3x -1 = 0 ⇒ x = 1/3
The zeros of the function are -2/5 and 1/3.
The larger zero is 1/3.

Answer:
x = 10
Step-by-step explanation:
Both obects are similar right. That means that they must have similar angles, similar sizes and similar scale factors.
For me by just looking at the figires I can conclude a similar scale factor which is 1.7. However we are going to calculate the scale factor.
First we must take notice that the triangle D'E'F' is an enlargement. So to find the scale factor we must the same sides of both triangle and divide the larger sid by the smaller side.
68 ÷ 40 = 1.7
Now that we have the scale factor (1.7) we can now find x.
The similer side D'F' = 17 and DF = x.
We are gonna use the scale factor to divide D'F' to find DF.
17 ÷ 1.7 = 10
Therefore x is 10

Every day, the Sandoval Family Restaurant serves 5/6 of a bottle of soda to their customers. How many days will 7 1/2 bottles of soda last?
Answer:
9 days
Step-by-step explanation:
1 day: 5/6 2 days: 10/6 3 days: 15/6 4 days: 20/6 5 days: 25/6
6 days: 30/6 7 days: 35/6 8 days: 40/6 9 days: 45/6
If you divide 45 and 6 by 3 you get 15/2. If you put 15/2 into a mixed number you would get 7 1/2. So 9 days would be your answer.
Answer:
7 1/2 bottles will last 9 days
Step-by-step explanation:
To answer this, divide '7 1/2 bottles' by '5/6 bottle per day:"
7 1/2 bottles
-----------------------
5/6 bottle/day
The unit "bottle"/"bottles" cancel, and so we are left with
7 1/2 day
------------------- and this is equivalent to 15 days/2 divided by 5/6 OR
5/6
15 days/2 times 6/5:
15(6)
--------- days = 18/2 days = 9 days (answer)
2(5)
7 1/2 bottles will last 9 days.

Answer:

Step-by-step explanation:
Hello!
Let's simplify the left side:
- ( -9 ) 9Remember that the negative sign also means opposite, so the opposite of negative 9 is positive 9.
Let's simplfy the right side:
| - 9 |9Remember that in an absolute value bracket, any positive value stays positive, but any negative value turns to the positive value.
So the inequality is 9 _ 9
Therefore the sign should be "=" as 9 is equal to 9.

What are the coordinates of point A? (8, –6) (–6, 8) (–5, 7) (7, –5) giving 100 point
Answer:(7,-5)
From a x axis point is 7
From a y axis point is -5
Thus coordinates are (7,-5) because in any point coordinates are always in the form (x,y).
Hope this Helps! :)
Answer:
D. (7, -5)
Step-by-step explanation:
A coordinate is a point on a graph. A coordinate is written as (x, y), where x represents the x-value and y represents the y-value.The x-value represents the number of units left or right from the origin (0, 0), and it becomes negative as it moves left and positive as it moves right.The y-value represents the number of units up or down from the origin (0, 0), and it becomes negative as it goes down and positive as it goes up.For example, the coordinates (-4,8) indicate that the x-value moves four units to the left and the y-value moves eight units up.We are asked to find the coordinates of point A:
The x-value is positive 7, indicating that the point moved seven units to the right of the origin.The y-value is negative 5, indicating that the point dropped five units from the origin.Our coordinates would be: (7, -5)Learn more about graphing coordinates here:

−(−3)+(−3)^2

Good luck! Hope this helps!
Answer:
the answer for this question should be 6 because remember we need to substitue n by -3 so first we need to solve the exponent one so we replace it.
-3^2= 9
-3 times -3= 9 and remember this rule when we multiply an negative times a negative is positive so it would be 9 for n^2 so we need to add 9+-3 and we get an answer of 6 so 6 is the correct answer and remember if the base is an negative and the exponent is even the answer is positive but if it is odd it would be negative.
hopefully 6 is the correct and have a great day.

What is the circumstance of the circle? (3.14 for pi)
Answer:
131.88in
Step-by-step explanation:
C = 2πr
The radius of the circle is from center to the perimeter.
In this case the radius is 21in.
3.14 for pi
C = 2(21)(3.14)
C = 42(3.14)
C = 131.88in
Answer:
the answer for this question should be 131.88 because 21 is the radius and the radius is half of the diameter which is 42 because you need to multiply 21 times 2 getting an answer for the diameter but we use the formulas.
C=2 times 3.14 times 21= 131.88
C= 3.14 times 42=131.88

37. One half of the water is poured out of a full container. Then one third of the remainder is poured out. Continue the process: one fourth of the remainder for the third pouring, one fifth of the remainder for the fourth pouring, etc. After how many pourings does exactly one ninth of the origiNl water remain?
Hint: What fraction of the water remains after 1 pour? After 2 pours? After 3 pours?
After the first pour the water remains 1/2, after the second 1/3, after the third is 1/4, and after 9 pour the water remains 1/10.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
After the first pour container has = 1/2
After the second pour = 1/3
Third pour = 1/4
After n pour = 1/(n+1)
n = 9
= 1/10
Thus, after the first pour the water remains 1/2, after the second 1/3, after the third is 1/4, and after 9 pour the water remains 1/10.

which graph represent the liner function y= 1/3 x -4?
Answer:
Graph 3
Step-by-step explanation:
equation: y = mx + b → y = 1/3x - 4
- m is the slope (slope = rise / run):
- b is the y intercept (when x = 0): -4
Graph 1 is incorrect because the y-intercept is 1.5 on this graph when the equation is -4
Graph 2 is incorrect because the slope is 3 / 1, the rise is 3 and the run is 1
the correct equation for this graph is y = 3x - 4
Graph 3 is correct because the slope is 1/3, the rise is 1 and the run is 3
and the y intercept is -4
Graph 4 is incorrect because the y-intercept is not even shown

What is the distance around the circle?
314 feet
20 feet
31.4 feet
62.8 feet
Answer:
62.8 feet
Step-by-step explanation:
The distance around the circle is known as the circumference
We can find the circumference using the formula C = 2πr
Where r = radius
The radius is a line that goes from the center of the circle to any point on the circle.
Here, we are given that the radius is 10 feet
Plugging in the value of the radius into the circumference formula
Again we have C = 2πr
==> plug in r = 10
C = 2π(10)
==> multiply 10 and 2
C = 20π
==> multiply 20 and π (which has a value of about 3.14)
C = 62.8 ( rounded )
So the distance around the circle is about 62.8 feet.

Answer:
62.8 feet
Step-by-step explanation:
We are given:
[tex]\text{Radius of circle} = \bold{10} \ \bold{feet}[/tex]
Definition of radius: The radius of the circle is the line that starts from the center point and ends at any point of the circle.
The formula that expresses the circumference of a circle is 2πr. [Where "r" represents the radius of the circle]
Let's substitute the radius in the circumference formula and simplify it to determine the distance around the circle (circumference).
[tex]\implies \text{Circumference of circle} = 2\pi r[/tex]
[tex]\implies \text{Circumference of circle}= 2\pi (10)[/tex] [tex]\implies \text{Circumference of circle} = 20\pi[/tex]
Let us take π as 3.14. Then, we get:
[tex]\implies \text{Circumference of circle} = 20(3.14) = 2(31.4) = \boxed{62.8 \ \text{feet}}[/tex]
Therefore, the distance around the circle (circumference) is 62.8 feet.
