On solving the quadratic function x²+6x+8, the solutions x = -4 and x = -2 are obtained.
What is a quadratic function?
A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. It is also known as the polynomial of degree 2 since the greatest degree term in a quadratic function is of second degree.
The given quadratic function is - x²+6x+8
To solve the function first multiply - 8 × x² = 8x²
Take the LCM of 8x².
8x² = 2 × 2x × 2x
Now, we need to form such two numbers that if added or subtracted gives 6x and when multiplied gives 8x².
8x² = 4x × 2x
6x = 4x + 2x
Factorize the equation using the numbers obtained -
= x²+6x+8
= x²+ 4x + 2x + 8
= x(x + 4) +2(x + 4)
= (x + 4)(x + 2)
This gives the value as x = -4 and x = -2.
Therefore, the solution points are x = -4 and x = -2.

Need help w this problem
Answer:
9, 18Step-by-step explanation:
The key word "product" tells us to multiply.
And, you probably know, but "integer" just means "number".
The question is, essentially:
A × B = 162 where A is half of B.
As someone who was never gifted in math, my best suggestion for something like this is to grab a calculator and start dividing 162 by all the numbers below 10. You will know you've got your answer when the calculator gives you a number that is twice the number you divided by.
In this case, I divided 162 by 9 and got 18. Since 9 is half of 18, and multiplied they make 162, we know this is the correct answer.
Hope this helps
How many different ways are there to choose a dozen donuts from the 4 varities at a donut shop so that you get atleast one donut of every variety g
There are 330 different ways for choosing a dozen donuts from the 4 varieties at a donut shop. (at least one donut of every variety must be selected)
How to calculate the number of ways to select items?There are 'r' items from 'n' different varieties (repetition allowed). Then, the number of ways to select items is given by
The number of ways = [tex]_{n+r-1}C_r[/tex]
Where the combination [tex]_{n}C_r[/tex] is calculated as
[tex]_{n}C_r=\frac{n!}{r!(n-r)!}[/tex]
Calculation:It is given that there are 4 varieties of donuts in a shop. I.e., n = 4
Number of donuts to be selected r = 12 (one dozen)
And also given that at least one donut of every variety has to be selected.
Since there are 4 varieties, at least one from each of these means the count is 4.
So, the remaining number of donuts to be selected is 12 - 4 = 8.
So, r becomes 8 i.e., r = 8
On substituting,
the number of ways of selecting the remaining 8 donuts = [tex]_{4+8-1}C_4[/tex]
⇒ [tex]_{11}C_4[/tex]
⇒ [tex]\frac{11!}{4!(11-4)!}[/tex]
⇒ [tex]\frac{11!}{(4!)(7!)}[/tex]
⇒ 330
Therefore, there are 330 different ways for choosing a dozen donuts from the 4 varieties at a donut shop.

Answer:
[tex]254 \frac{12}{17}[/tex] or approximately 254.71
Step-by-step explanation:
First, you need to find out how many gallons it will take to travel 866 miles. Because the car's avg miles/gallon is 13.6, you divide 866 by 13.6. However, this gets you an irrational number. To avoid this, make 13.6 into a fraction. Now divide 866 by [tex]13 \frac{3}{5}[/tex]. This becomes 866 ÷ [tex]\frac{68}{5}[/tex]. Convert this into a multiplication problem by converting [tex]\frac{68}{5}[/tex] into its reciprocal. This gets you 866 × [tex]\frac{5}{68}[/tex]. This gets you [tex]\frac{2165}{34}[/tex]. Now that you have the amount of gallons it will take to get to your destination, multiply it by 4. [tex]\frac{2165}{34}[/tex] × [tex]4[/tex][tex]= \frac{4330}{17}[/tex]. This becomes [tex]254 \frac{12}{17}[/tex] or approximately 254.71.

Answer:
A. (-1, 3) (3, 2) (-2, 1)
B. [tex]\sqrt{17}[/tex] [tex]\sqrt{5}[/tex] [tex]\sqrt{26}[/tex]
Step-by-step explanation:
The formula for finding the midpoints is [tex](\frac{x_{1}+x_{2} }2}, \frac{y_{1}+y_{2} }2} )[/tex].
MIDPOINTS
[tex](\frac{x_{1}+x_{2} }2}, \frac{y_{1}+y_{2} }2} )[/tex] = [tex](\frac{4-6}2,\frac{4+2 }2} )[/tex] = (-1, 3)
[tex](\frac{x_{1}+x_{2} }2}, \frac{y_{1}+y_{2} }2} )[/tex] = [tex](\frac{4+2}2,\frac{4+0 }2} )[/tex] = (3, 2)
[tex](\frac{x_{1}+x_{2} }2}, \frac{y_{1}+y_{2} }2} )[/tex] = [tex](\frac{-6+2}2,\frac{2+0 }2} )[/tex] = (-2, 1)
Next, we will use the distance formula, [tex]\sqrt{(x_{1}-x_{2})^{2} + (y_{1}-y_{2})^{2} }[/tex].
DISTANCE
[tex]\sqrt{(x_{1}-x_{2})^{2} + (y_{1}-y_{2})^{2} }[/tex] = [tex]\sqrt{(-1-3)^{2} + (3-2)^{2} }[/tex] = [tex]\sqrt{17}[/tex]
[tex]\sqrt{(x_{1}-x_{2})^{2} + (y_{1}-y_{2})^{2} }[/tex] = [tex]\sqrt{(-1+2)^{2} + (3-1)^{2} }[/tex] = [tex]\sqrt{5}[/tex]
[tex]\sqrt{(x_{1}-x_{2})^{2} + (y_{1}-y_{2})^{2} }[/tex] = [tex]\sqrt{(3+2)^{2} + (2-1)^{2} }[/tex] = [tex]\sqrt{26}[/tex]

(2+4)/2=3 (4+0)/2=2
Coordinates of midpoints are (-1,3), (-2,1), (3,2)
b. Now we use the distance formula for each midpoint to find the length of the inner- triangle.
sqrt((-1+2)^2 + (3-1)^2)
Sqrt(5)
Repeat.
Sqrt(17)
Sqrt(26)
The lengths of the inner triangle are as follows:
(-1,3), (-2,1) = Sqrt(5)
(-1,3), (3,2) = Sqrt(17)
(-2,1), (3,2) = Sqrt(26)
Gelatin Methacryloyl Hydrogels in the Absence of a Crosslinker as 3D Glioblastoma Multiforme (GBM)-Mimetic Microenvironment
For the eradication of malignancies like the aggressive type of human brain tumour known as glioblastoma multiforme (GBM), 3D platforms are crucial for tracking tumour growth and assessing treatment candidates.
What is Glioblastoma Multiforme (GBM)?Glioblastoma (GBM), commonly known as a grade IV astrocytoma, is an aggressive brain tumour that grows quickly. The local brain tissue gets invaded, but it typically does not spread to distant organs. GBMs can develop from lower-grade astrocytomas or develop from new brain tumours.
Some characteristics of GBM are-
We explore cellular behavior, expression profiles of malignancy, and apoptosis-related genes within this novel network using suspension and spheroid-based models of GBM. In-depth research is also done on the sensitivity to the anticancer medication Digitoxigenin. According to the research, GelMA hydrogels contain high levels of prosurvival Bcl-2 gene expression and sparse or spheroid U373 cells, which have much lower expressions of apoptosis-activating genes like Bad, Puma, and Caspase-3.The up regulation of matrix-metalloproteinase genes within GelMA suggests that gels have a beneficial effect on the extracellular remodelling of cancer cells. Through the investigation of 3D malignant cancer cell behavior, this special photo curable gelatin shows significant promise for the practical translation of cancer research and, consequently, for more effective treatment techniques for GBM.To know more about brain tumour, here

A bag contains 1 white (W), 3 blue (B1, B2, B3), and 2 red (R1, R2) marbles. (4 points)
-Use a tree diagram to list all the possible outcomes for tossing a coin and then drawing a marble from the bag.-
SHOW ALL WORK
1. Are these independent or dependent events?
2. Find the probability of tossing a head and drawing a red marble. Explain your reasoning.
3. Find the probability of drawing two blue marbles if the first marble is not replaced. Explain your reasoning.
These are independent events
and probability of drawing red marble is 1/3
and probability of drawing two blue marble is 1/2 ,1/2.
According to the statement
A bag contains 1 white (W), 3 blue (B1, B2, B3), and 2 red (R1, R2) marbles.
And we have to find the probability of tossing a head and drawing a red marble. and probability of drawing two blue marbles if the first marble is not replaced.
here we solve this problem by Probability
So, Probability of drawing red marble = Number of red marble / total number of marbles.
Probability = 2/6
Probability = 1/3.
Then
Probability of drawing blue marbles = number of blue marbles /total marbles
Probability = 3/6
Probability = 1/2.
1st blue marble Probability =1/2
2nd blue marble Probability = 1-(1/2) = 1/2.
These are non dependent events because they do no affect the probability of each others.
So, These are independent events
and probability of drawing red marble is 1/3
and probability of drawing two blue marble is 1/2 ,1/2.
