Answer:
Subtract 5k from -k then you get
-6k + 4 =1
add 4 to both sides
-6k = -3
divide by -6 on both sides
k= -3/-6
simplify to get k= 1/2
Step-by-step explanation:
Answer:
k = 1/2
Step-by-step explanation:
-k - 5k = -6k
you minus 4 from each side
-6k = -3
you divide -6 from each side and you get-3/-6
which equals 1/2
Macha is a day care provider and has three tables with children eating lunch as shown on the grid. Where should Macha stand to be equidistant from all three tables?
According to the information, the coordinate that indicates the equidistant point to the three tables is 11/3, 5
How to find the equidistant point to the three tables?To find the equidistant point to the three tables we must take into account the coordinates of the three tables as shown below:
A = (1, 8) = (x1, y1)B = (3, 2) = (x2, y2)C = (7, 5) = (x3, y3)So to find the center we must apply the following formula:
(x1 + x2 + x3 / 3, y1 + y2 + y3 / 3)= (3 + 1 + 7 / 3, 8 + 2 + 5 / 3)= (11/3, 15/3)= (11/3, 5)Note: This question is incomplete. Here is the complete information:

suppose there is a population of 100 rabbits. in this population, 60 rabbits are ff, 20 are ff, and 20 are ff. what is the allele frequency for the f allele in this population's gene pool?
The allele frequency for the f allele in this population's gene pool is 0.6. This means that out of all the alleles in the gene pool, 60% of them are the f allele.
The total number of rabbits carrying the f allele (60) can be divided by the total number of alleles in the gene pool to arrive at this figure (100).
As a result, 0.6 or 60% of the population's gene pool contains the f allele. With frequencies of 0.2 and 0.2, respectively, for the other two alleles, ff and ff, it may be concluded that the f allele is more prevalent.
This also indicates that the f allele, which has the highest frequency, is the most prevalent allele in the population.

D-8= 12d o se puede escribir D= 12d+8
luego sustituya D= 12d+8 por D+d= 203
D+d= 203
(12d +8) +d= 203

1 Find the indicated derivative. Find f(3)(x) if f'(x) = 4 +2 x² + 5
first derivative f'(x) = 4 + 2x² + 5
second derivative f''(x) = d/dx (4 + 2x² + 5)⇒f''(x) =0 + d/dx(2x²) + 0⇒f''(x)= 4x
third derivative f'''(x) = d/dx (4x)⇒ f'''(x) = 0 + 4(d/dx(x)) + 0⇒ f'''(x) = 4 Therefore, f''(3)(x) = 4*3 = 12
Given, f'(x) = 4 + 2x² + 5To find, f''(x) and f'''(x)We have to differentiate f'(x) to obtain the second derivative of the given function
f'(x) = 4 + 2x² + 5 ⇒ f''(x) = d/dx (4 + 2x² + 5)⇒ f''(x) = 0 + d/dx(2x²) + 0⇒ f''(x) = 4x

First, we can find the top and bottom smaller squares of the rectangular prism. Since we are working with a variety of rectangles, we only need to use the equation L×W.
To start with, let's multiply 2×3, which gives us 6, the surface area of both the bottom and top rectangles, so now we need to multiply it by 2 to account for both of them. 6×2=12
Now, we'll find the surface area of the bigger rectangles in the middle, which are 6 by 3, so again we will need to multiply length times width, then by 2 to count both rectangles. 6×3=18×2=36
Finally, we can find the surface area of the smaller rectangles in the middle, which are 6 by 2. 6×2=12, then multiply by 2 since there are 2 of those rectangles, 12×2=24
Now to find the total surface area, we need to add the gathered surface area from each shape, 12+36+24=72

The first three terms of a sequence are given
30, 150, 750,
Write the explicit formula for the sequence.
Answer:
To find the explicit formula for the sequence, we need to determine the common ratio between each term.
The common ratio is found by dividing any term by the previous term. For example:
The common ratio between the second and first terms is 150/30 = 5.
The common ratio between the third and second terms is 750/150 = 5.
Since the common ratio is the same for all terms, we can use it to find any term in the sequence.
Let's call the first term a₁, and let r be the common ratio. Then we have:
a₁ = 30
a₂ = a₁ * r = 30 * 5 = 150
a₃ = a₂ * r = 150 * 5 = 750
a₄ = a₃ * r = 750 * 5 = 3750
a₅ = a₄ * r = 3750 * 5 = 18750
We can see that the explicit formula for the sequence is:
aₙ = a₁ * r^(n-1) = 30 * 5^(n-1)
Therefore, the explicit formula for the sequence is aₙ = 30 * 5^(n-1).

7. How many ordered triples of integers (x, y, z) satisfy 36x² + 100y² +2252² = 12600?
We need to find the number of ordered triples of integers (x, y, z) that satisfy the equation \(36x² + 100y² + 225z² = 12600\). The answer is 9 and 25
To determine the number of solutions, we can analyze the given equation modulo various numbers. First, we note that the left side of the equation is divisible by 9, as 36x² and 225z² are divisible by 9. Therefore, the right side must also be divisible by 9.
Analyzing modulo 9, we find that 12600 ≡ 0 (mod 9). Hence, the sum of the digits of 12600 is divisible by 9. The sum of the digits is 1 + 2 + 6 + 0 + 0 = 9, which is indeed divisible by 9.
Next, we consider modulo 25. The left side of the equation is divisible by 25 since 100y² is divisible by 25. Hence, the right side must also be divisible by 25.
Analyzing modulo 25, we find that 12600 ≡ 0 (mod 25). Thus, the number 12600 is divisible by 25.
By combining the divisibility results from modulo 9 and modulo 25, we can conclude that 12600 is divisible by both 9 and 25.
Therefore, to find the number of ordered triples of integers (x, y, z) that satisfy the equation 36x² + 100y² + 225z² = 12600, we need to count the number of factors of both 9 and 25 in 12600. This can be achieved by prime factorizing 12600 and determining the powers of 3 and 5.
In conclusion, the number of ordered triples of integers (x, y, z) that satisfy the equation 36x² + 100y² + 225z² = 12600 can be found by counting the factors of 9 and 25 in 12600.

Answer: 65%
Step-by-step explanation:
People saying that they would buy the car again means that they are satisfied with the car. There are therefore 1,105 people who are satisfied with the car.
The percent of people satisfied is:
= Number of satisfied people / Total number of people surveyed * 100%
