Value of x when y = 17 for the quadratic function f(x) = x² + 6x + 10 is -7 and 1. That is option E.
Given, y=17 :
17 = x² + 6x + 10
Move 17 to RHS (right-hand side) :
0 = x² + 6x - 7
Using the Middle Splitting method:
0 = x² + (7x - 1x) - 7
0 = x(x + 7) - 1(x+7)
0 = (x - 1) (x + 7)
Now, equate both the equations (x-1) and (x+7) separately with 0.
The first value of x is
(x - 1) = 0
x = 1
The second value of x is
(x + 7) = 0
x = -7
∴ The values of x are -7 and 1. According to the question, that is option E.

math.uh.edu lloyd's cereal company packages cereal in 1 pound boxes (16 ounces). a sample of 25 boxes is selected at random from the production line every hour, and if the average weight is less than 15 ounces, the machine is adjusted to increase the amount of cereal dispensed. if the mean for 1 hour is 1 pound and the standard deviation is 0.1 pound, what is the probability that the amount dispensed per box will have to be increased?
The probability that the amount dispensed per box will have to be increased is 0.0062.
Consider the provided information.
Sample of 16 boxes is selected at random.
If the mean for 1 hour is 1 pound and the standard deviation is 0.1
1 Pound = 16 ounces , then 0.1 Pound = 16/10 = 1.6 ounces
Thus: μ = 16 ounces and σ = 1.6 ounces.
Compute the test probability
z= x−μ/σ/[tex]\sqrt{n}[/tex]
z= 15-16/ 1.6/[tex]\sqrt{4}[/tex]
z= -1/ 0.4
z= -2.5

4. Find “a” so that the parabola y = ax² + 3x + 11 goes through the point (3,2).
Answer:
a = - 2
Step-by-step explanation:
since the point (3, 2 ) lies on the parabola, then it makes the equation true.
substitute x = 3, y = 2 into the equation and solve for a
y = ax² + 3x + 11
2 = a(3)² + 3(3) + 11
2 = 9a + 9 + 11
2 = 9a + 20 ( subtract 20 from both sides )
- 18 = 9a ( divide both sides by 9 )
- 2 = a
Answer:
a = -2
Step-by-step explanation:
Given quadratic equation:
[tex]y=ax^2+3x+11[/tex]
In order to find "a", substitute the given point on the curve (3, 2) into the equation and solve for a:
[tex]\begin{aligned}y&=ax^2+3x+11\\\textsf{Substitute $(3,2)$} \implies 2&=a(3)^2+3(3)+11\\2&=9a+9+11\\2&=9a+20\\2-20&=9a+20-20\\-18&=9a\\9a&=-18\\\dfrac{9a}{9}&=\dfrac{-18}{9}\\\implies a&=-2 \end{aligned}[/tex]
Therefore, the value of "a" so that parabola y = ax² + 3x + 11 goes through the point (3, 2) is:

Step-by-step explanation:
I guess you want to draw the graph.
The graph is a straight line
-6x - 20 = 4y
When x = 0:
-6(0) - 20 = 4y
y = -20/4 = -5
So, one point on the graph

When y = -2:
Plugging y = -2 into the equation:

The measures of the unknown angles are as follows:
∠DEA = ∠BEC = 60°∠AEB = ∠CED = 120°How to find the measure of angles?The measures of each angles can be found as follows:
Therefore,
∠AEB = ∠CED (vertically opposite angle)
∠DEA = ∠BEC (vertically opposite angle)
Vertically opposite angles are equal.
Therefore,
4x = 75 - x
4x + x = 75
5x = 75
x = 75 / 5
x = 15
Therefore,
∠DEA = ∠BEC = 4(15) = 60°
∠AEB = ∠CED = 360 - 120 / 2 = 240 / 2 = 120°

A certain plant grows 1 1/6 inches each werk how long will it rake the plant to grow 6 1/6 inches?
A certain plant grows 1 1/6 inches each week. it will rake the plant to grow 6 1/6 inches is 5 weeks 2 days.
What is the definition of time?Time is ongoing progression of existence and things that happen in what seems to be an irrevocable order from the past, present, and forward into the future. It is a quantity that is part of several measurements that are used to compare the length of events or the gaps between them, to compare how long they last, to order events, and to measure how quickly the things change in the real world or in our conscious experience. Along with the three spatial dimensions, time is frequently referred to as a fourth dimension.
Time has long been an important subject of study in religion, philosophy, and science, but defining it in a manner applicable to all fields without the circularity has consistently eluded scholars. Nevertheless, diverse fields such as the business, industry, sports, sciences, and the performing arts all incorporate some notion of time into their respective measuring systems.
A certain plant grows every week = [tex]1\frac{1}{6}[/tex] = [tex]\frac{7}{6}[/tex] inches
1 week = 7 days
Therefore in 1 day plant grows = [tex]\frac{\frac{7}{6} }{7}[/tex]
= [tex]\frac{1}{6}[/tex] inch
Now we have to calculate the number of days in which the plant grows [tex]6\frac{1}{6}[/tex] inches ≈ [tex]\frac{37}{6}[/tex] inch
Number of days = [tex]\frac{Total growth}{growth in one day}[/tex]
= [tex]\frac{37}{6}[/tex] ÷ [tex]\frac{1}{6}[/tex]
= [tex]\frac{37}{6}[/tex] × 6
= 37 days ≈ 5 weeks and 2 days
It will take plant 5 weeks 2 days to grow [tex]6\frac{1}{6}[/tex] inches.

The length of a corresponding line segment in the image is; Nz
How to find the Slope of the Line Segment?We know that;
Slope is the ratio of change in y-value and change in x-value.
Thus, dilation does not change the slope of any line.
Now, after dilation; M---->M
Length of line:
We know that a dilation has the effect of stretching or shrinking the line segment by the factor of N units
We are given

Which number is located between 11 and 12 on a number line?
A.
√150
B.
√134
C.
√115
D.
√121
√134 is the number which is located between 11 and 12 on a number line.
What is a Number Line?A number line is a horizontal straight line on which real numbers are arranged in equal intervals. This line extends both sides at infinity.
Comparison and operations of numbers can be better explained using number lines.
Taking consecutive perfect squares of integers which lies above and below the given numbers on the number line and taking it's square root, we can find the answer.
The perfect squares below and above 150 are 144 = 12² and 169 = 13². So √150 lies in between 12 and 13.
The perfect squares below and above 134 are 121 = 11² and 144 = 12². So √134 lies in between 11 and 12.
The perfect squares below and above 115 are 100 = 10² and 121 = 11². So √115 lies in between 10 and 11.
The number 121 is itself a perfect square. √121 = 11.
Hence √134 is the number which lies in between 11 and 12.
