What are the values of a1 and r of the geometric series? 2 â€"" 2 2 â€"" 2 2.
The values of [tex]a_1[/tex] is 2 and r are -1 of the geometric series and it can be determined by using geometric summation operation.
Given that,
The geometric series is,
2 – 2 + 2 – 2 + 2
We have to determine
What are the values of a1 and r of the geometric series?
According to the question,
Geometric series;2 – 2 + 2 – 2 + 2
The geometric series [tex]a_1[/tex] is the first term of the geometric sequence and r is the common ratio of the geometric series.
The first term of the given geometric series is 2.
And the common difference in the given geometric series is,
[tex]\rm r = \dfrac{a_2}{a_1}[/tex]
Where [tex]a_1[/tex] is the first term of the geometric sequence and [tex]a_2[/tex] is the second term of the geometric sequence.
Then,
The common difference in the given geometric series is,
[tex]\rm r = \dfrac{-2}{2}\\\\r = -1[/tex]
The common ratio in the given geometric series is -1.
Hence, the values of [tex]a_1[/tex] is 2 and r is -1 of the geometric series

The ratio of cats to dogs seen at CyFair Animal Hospital is 2 to 5. If Dr. Blue, Dr. Ross, and Dr. Lavigne see 40 dogs altogether, how many cats AND dogs did they see in all? Explain your answer.
Please
The number of cats and dogs the doctor saw is 56.
Ratio expresses the relationship between two values. It shows the frequency that one value is contained another value. The sign of ratio is :.
The equation that can be used to determine the total number of dogs that the doctor saw is:
(ratio of dog / total number of dogs and cats) x total number of animals = number of dogs
5/7 x a = 40
Where a is the total number of dogs and cats
In order to determine the value of a, divide both sides of the equation by 7/5.
40 x 7/5 = 56

The quadratic function f(x)= x^2-14x+53 is equal to zero when x=a+ or - bi
What is the value of a?
What is the value of b?
Answer:
A= 3x B= 6/8
Step-by-step explanation:
The value of a is 7, and the value of b is 2√(2) for the given quadratic function f(x) = x² - 14x + 53.
What is a quadratic function?The quadratic function is defined as a function containing the highest power of a variable is two.
The quadratic function f(x) = x² - 14x + 53 is equal to zero when x = a + bi or x = a - bi. This means that the roots of the quadratic equation are a + bi and a - bi.
The roots of a quadratic equation can be found using the quadratic formula:
x = (-b +/- √(b² - 4ac)) / (2a)
In this case, a = 1, b = -14, and c = 53. Substituting these values into the quadratic formula, we get:
x = (-(-14) +/- √((-14)² - 4153)) / (2*1)
x = (14 +/- √(196 - 212)) / 2
x = (14 +/- √(-16)) / 2
Since the square root of a negative number is an imaginary number, the roots of the quadratic equation are a + bi and a - bi, where a = 14/2 = 7 and b = √(-16)/2 = 2√(2).
Therefore, the value of a is 7, and the value of b is 2√(2).
