2. I do the punnet square method, but I can't solve it
3. Equals 2(2x-3)(x-9)
Question: How do I do the punnet square in a situation like this where there are number s outside of the parentheses?
Answers
Answer: y = 2(2x^2 - 21x +27) this should help you do the punnet square if you focus inside the parenthesis
Step-by-step explanation:
for y = 4x^2 - 42x + 54 we can factor out a 2 so
y = 2(2x^2 - 21x + 27)
More to the answer...
We can seperate - 21x into -3x and -18x (focusing on the inside of the parenthesis)
2x^2 -3x -18x + 27 for 2x^2 - 3x we can factor out an x and for -18x + 27 we can factor out -9
2( x(2x-3) -9(2x-3) ) we can factor out 2x -3 so now it is
2(2x-3)(x-9)

Social scientists gather data from samples instead of populations because
a. samples are much larger and more complete.
b. samples are more trustworthy.
c. populations are often too large to test.
d. samples are more meaningful and interesting
Answers
Social scientists gather data from samples instead of populations because c. populations are often too large to test.
Social scientists often cannot test an entire population due to its size, so they gather data from a smaller group or sample that is representative of the larger population. This allows them to make inferences about the larger population based on the data collected from the sample. The sample size must be large enough to accurately represent the population, but it is not necessarily larger or more complete than the population itself. Trustworthiness, meaning, and interest are subjective and do not necessarily determine why social scientists choose to gather data from samples.

a bike that goes from 6m/s to 16m/s in 20 seconds.
Answers
The initial velocity = vi = 6m/s
The final velocity = vf = 16 m/s
The total time = t = 20 seconds
The rate of change in velocity is called acceleration (a) that can be written as:
\(a\text{ = }\frac{Change\text{ in velocity}}{time}\)
or
\(a\text{ = }\frac{vf-vi}{t}\)Put the values in the equation to get the value of 'a'.
\(a\text{ = }\frac{16\text{ - 6}}{20}\)\(a\text{ = }\frac{10}{20}\)or
\(a\text{ = }\frac{1}{2}\)hence, the value of a is 1/2.
Ali used 1 1/4 pints of watermelon and 5 1/8 pints of strawberries to make fruit salad how many pints of watermelon and strawberries were used in all?
Answers
Answer:
Step-by-step explancacacaccaaaaation:
1 1/4 = 5/4
5 1/8 = 41/8
To convert the fractions, we need to multiply the numerator and denominator of the first fraction by 8 (the denominator of the second fraction), and multiply the numerator and denominator of the second fraction by 4 (the denominator of the first fraction):
5/4 x 8/8 = 40/32
41/8 x 4/4 = 164/32
Now we can add the two fractions:
5/4 + 41/8 = 40/32 + 164/32 = 204/32
We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor (GCF), which is 4:
204/32 = 51/8
Therefore, Ali used a total of 51/8 pints of watermelon and strawberries in the fruit salad.
The price for calculating the price to deliver a parcel of mass m kg is price ($) = 7 + 3.5m
What is the mass, in kg, of a parcel with a delivery price of $70?
Answers
Answer:
18 Kg
Step-by-step explanation:
We can use algebra to solve for the mass, m, given the delivery price, $70.
Starting with the formula:
price ($) = 7 + 3.5m
We can substitute $70 for price ($) and solve for m:
$70 = 7 + 3.5m
Subtracting 7 from both sides:
$63 = 3.5m
Dividing both sides by 3.5:
m = 18
Therefore, the mass of the parcel is 18 kg.
A cotton candy vendor has 27 cones of blue cotton candy to sell. If the blue cotton candy is 75% of the total number of cones, how many total cotton candy cones does he have?
Answers
Answer:
36
Step-by-step explanation:
Let the total number of cotton candy = A
Number of blue cotton candy = 27 cones
Percentage of blue cotton candy = 75%
Therefore, the total number of cotton candy is calculated as:
27/A × 100 = 75%
2700/A = 75
Cross Multiply
75A = 2700
A = 2700/75
A = 36
Therefore, the amount of total cotton candy that we have is 36.

Exercise 3.5.3: What happens in the case when P we have drawn? ]?Does this look like any of the pictures Exercise 3.5.4: Which behaviors are possible if P is diagonal, that is P] You can assume that a and b are not zero.
Answers
a) To convert the second-order equation into a system of first-order equations, we introduce a new variable, say y, and its derivative y'. The original equation becomes:
x' = y
y' = (-c/m)x - (k/m)x
b) The behavior of the system depends on the values of m, c, and k.
- If m > 0, c = 0, and k > 0, we have an undamped system with no damping force. It exhibits simple harmonic motion.
- If m > 0, c > 0, and k > 0, we have a damped system with a damping force. The behavior depends on the damping ratio, which can be underdamped, critically damped, or overdamped.
- If m > 0, c = 0, and k = 0, we have a mass-spring system without any external forces. The behavior is characterized by free oscillations.
c) In this particular mass-spring system, we do not observe all possible behaviors because the equation assumes certain physical constraints. For example, the equation neglects external forces or nonlinearities, which can introduce additional behaviors like chaotic motion or limit cycles.
Exercise 3.5.2:
When P - λd11, where λ is a repeated eigenvalue and there is only one independent eigenvector, the solution exhibits degenerate behavior. Geometrically, this corresponds to a repeated eigenvalue with a single linearly independent eigenvector, which gives rise to a trajectory along a line in phase space.
Exercise 3.5.3:
When P is drawn, it represents a Jordan block in the matrix representation. In this case, the system exhibits a nontrivial generalized eigenvector behavior. The phase portrait may have a spiral or swirling pattern around an equilibrium point or a limit cycle, depending on the specific values in the Jordan block.
Exercise 3.5.4:
If P is diagonal, that is P = diag(a, b), the behaviors possible are decoupled or independent oscillations along the coordinate axes. Each component of the system evolves independently according to its respective eigenvalue, leading to distinct motions in different directions.

(PLZ NEED HELP) The doubling time of a bacterial population is 10 minutes. After 80 minutes, the bacterial population was 80000. _____
Using your rounded answer for the initial population above (do not round your growth rate), find the size of the bacterial population after 5 hours.____
Answers
Answer:
Initial population = 313
Population after 5 hours = \(3.36 \times 10^{11}\)
Step-by-step explanation:
Let initial population = \(x\)
It is given that population gets doubled every 10 minutes.
Population after 10 minutes = \(2x\)
Population after 20 minutes = \(2^{2} x\)
:
:
Population after 80 minutes = \(2^{8} x\) and it is given as 80000.
\(\Rightarrow 2^{8} x = 80000\\\Rightarrow x = \dfrac{80000}{256}\\\Rightarrow x = 313\)
So, initial population is 312.5 = ~313
To find, population after 5 hours i.e. 5 \(\times\) 60 = 300 minutes
Population after 300 minutes =
\(2^{30} x\\\Rightarrow 2^{30} \times 313\\\Rightarrow 3.36 \times 10^{11}\)
So, the answers are:
Initial population = 313
Population after 5 hours = \(3.36 \times 10^{11}\)

Step-by-step explanation:
The sum of N consecutive natural numbers is given by:
\(\displaystyle S_N=\frac{N}{2}(F+L)\)
We need to find the sum of the natural numbers between 12 to 38.
To calculate the required sum we have F=12, L=38, but we don't have the value of N.
From 12 to 38 there are 38 - 12 + 1 = 27 natural consecutive numbers, thus N=27.
Substituting in the formula:
\(\displaystyle S_{27}=\frac{27}{2}(12+38)\)
\(\displaystyle S_{27}=\frac{27}{2}(50)\)

a flower store has an inventory of 2525 roses, 1515 lilies, 3030 tulips, 2020 gladiola, and 1010 daisies. a customer picks one of the flowers at random. what is the probability that the flower is not a rose?
Answers
The probability that the flower picked by the customer is not a rose is 0.75, or 75%. can be calculated by dividing the number of flowers that are not roses by the total number of flowers in the inventory.
In this case, the inventory has 2525 roses, and the total number of flowers in the inventory is the sum of the different types of flowers: 2525 + 1515 + 3030 + 2020 + 1010 = 10100.
To find the number of flowers that are not roses, we subtract the number of roses from the total number of flowers: 10100 - 2525 = 7575.
Therefore, the probability that the flower picked by the customer is not a rose is 7575/10100, which simplifies to 3/4 or 0.75.
So, the probability that the flower picked by the customer is not a rose is 0.75, or 75%.
