Complete the square x squared +18x-64=0
Answer:
x = -9±√145 (= 3.04 or -21.04)
Step-by-step explanation:
x²+18x-64 = 0 (move the constant to the right side, add 64 to both sides)
x²+18x = 64 (divide the x-term by 2, square it, then add it to both sides)
x²+18x + (18/2)²= 64 + (18/2)² (simplify)
x²+18x + 9²= 64 + 9²
x²+18x + 9²= 64 + 81
x²+18x + 9²= 145 (simplify left side using the property (a+b)² = a²+ 2ab+b²)
(x+9)² = 145 (take square root of both sides)
x+9 = ±√145
x = -9±√145 (= 3.04 or -21.04)

Since x did not come back to equal an answer, this problem is not workable. There is no solution to it. If you were to do it a different way, there still would not be a solution to it.
Suppose that the probability that a person will die in the next 20 years is
7.2698%. If this person has a life insurance policy that will pay out $60,00
the beneficiaries of the policy if the person dies in the next 20 years, what is
the premium of the policy? Assume that the administrative costs of the policy
amount to $75.
The premium of the policy is approximately $64,198.32.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To calculate the premium of the policy, we need to take into account the probability of the person dying in the next 20 years and the payout of the policy.
Let P be the probability of the person dying in the next 20 years, and let A be the administrative costs of the policy.
Then the expected value of the payout of the policy is:
E(payout) = P x $60,000
And the expected value of the cost of the policy (including administrative costs) is:
E(cost) = P x premium + A
We want to find the premium of the policy, so we can rearrange this equation to solve for the premium:
premium = (E(cost) - A) / P
Substituting the given values, we get:
P = 0.072698
A = $75
E(payout)
= P x $60,000
= 0.072698 x $60,000
= $4,361.88
Now we need to calculate the expected value of the cost of the policy.
The cost of the policy includes both the payout (if the person dies) and the administrative costs (whether or not the person dies).
So we can write:
E(cost) = E(payout) + A x (1 - P)
where (1 - P) is the probability that the person will not die in the next 20 years.
Substituting the given values, we get:
E(cost) = $4,361.88 + $75 x (1 - 0.072698) = $4,746.88
Finally, we can calculate the premium of the policy:
premium = ($4,746.88 - $75) / 0.072698 = $64,198.32
Therefore,
The premium of the policy is approximately $64,198.32.

What is the numerator of the simplified sum?
x/x^2 +3x+2 + 3/x+1
Question:
What is the numerator of the simplified sum?
x/x^2 +3x+2 + 3/x+1
Answer & Step-by-step explanation:
The given equation is as follows.
\frac{x}{x^{2}+3x+2} + \frac{3}{x+1}
Taking L.C.M, the equation will become as follows.
\frac{x(x+1)+ 3(x^{2}+3x+2)}{(x^{2}+3x+2)(x+1)} ........ (1)
Factorize the equation x^{2}+3x+2 in the denominator as follows.
x^{2}+3x+2
= x^{2} + 2x + x + 2
= x(x+2) + 1(x + 2)
= (x+1)(x+2) ........ (2)
Put the factors in equation (2) in to equation (1), then the equation will become as follows.
\frac{x(x+1)+ 3(x^{2}+3x+2)}{(x^{2}+3x+2)(x+1)}
= \frac{x^{2}+x +3x^{2}+9x+6)}{(x+1)(x+2)(x+1)}
= \frac{4x^{2}+10x+6}{(x+1)^{2}(x+2)}
Now, factorize the numerator as follows.
\frac{4x^{2}+10x+6}{(x+1)^{2}(x+2)}
= \frac{4x^{2}+4x+6x+6}{(x+1)^{2}(x+2)}
= \frac{4x(x+1) + 6(x+1)}{(x+1)^{2}(x+2)}
= \frac{(4x+6)(x+1)}{(x+1)^{2}(x+2)}
Cancelling (x+1) from both numerator and denominator. Then the equation will be written as follows.
\frac{(4x+6)(x+1)}{(x+1)^{2}(x+2)}
= \frac{(4x+6)}{(x+1)(x+2)}
The numerator of simplified sum is (4x+6).

What are the domain and range of the function?
f(x)=−35x3
Domain: (−∞, 0)∪ (0, ∞)
Range: (−∞, 0)∪ (0, ∞)
Domain: (−∞, 0)∪ (0, ∞)
Range: (−∞, 0)
Domain: (−∞, 0)∪ (0, ∞)
Range: (0, ∞)
Domain: (−∞, ∞)
Range: (−∞, 0)
The domain and the range of the functions is real numbers. Hence, option A is correct.
We need to determine the domain and range of the function [tex]\bold{f(x)=-35x^3}[/tex].
Let us define the domain and the range of the function:
Domain:
When all the possible values of an independent variable for which we get the real value of a dependent variable then the values of the independent variables is called domain of the function.
Range:
All the possible values of the function is called the range of the function. Range is the sub-set of co-domain.
Now,
For the given function [tex]f(x)=-35x^3[/tex].
No value of x can restrict the above function hence its domain is real number that is [tex](-\infty, +\infty)[/tex].
And, range of the function is also the same [tex](-\infty, +\infty)[/tex].
Thus, the domain and the range of the functions is real numbers. Hence, option A is correct.

The domain and range of the cubic function f(x) = -35x^3 are both all real numbers, because there are no restrictions on x and the function's output covers all real values.
Explanation:The function described is f(x) = −35x^3. The domain of a polynomial function, which includes cubic functions like this one, is all real numbers because there are no restrictions on the values that x can take. Therefore, the domain is (−∞, ∞). Since the leading coefficient of the cubic term is negative, the ends of the graph will go towards negative infinity as x goes to positive and negative infinity. Therefore, the range of the function is also all real numbers, which we write as (−∞, ∞).

Step-by-step explanation:
The two triangles Δ ABC and Δ A'B'C' are similar.
Here, ∠ A = ∠ A' = 104°, ∠ B = ∠ B' = 50° and ∠ C = ∠ C' = 26°.
Now, the length of AB and the length of A'B' are 4 cm and 2 cm respectively.
Again, the length of BC and the length of B'C' are 9 cm and 4.5 cm respectively.
Therefore, [tex]\frac{AB}{A'B'} = \frac{BC}{B'C'} = \frac{CA}{C'A'} = \frac{4}{2} = \frac{9}{4.5} = 2[/tex]

Line k passes through (2, -3) and (8,1). Which equation represents a line that is parallel to k? A. y = -2/3 x - 5/3 B. y = 2/3 x - 13/3 C. y = 3/2 x - 6 D. y = -3/2 x
Answer: B. y = 2/3 x - 13/3
Step-by-step explanation:
two lines are said to be parallel if they have the same slope.
To find the slope of line K we will use the formula fro calculating slope which is :
m = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]x_{1}[/tex] = 2
[tex]x_{2}[/tex] = 8
[tex]y_{1}[/tex] = -3
[tex]y_{2}[/tex] = 1
substituting into the values into the formula , we have :
m = [tex]\frac{1-(-3)}{8-2}[/tex]
m = [tex]\frac{4}{6}[/tex]
m = [tex]\frac{2}{3}[/tex]
Therefore : the slope of line K = [tex]\frac{2}{3}[/tex] , this means that any line that will be parallel to K must have a gradient of [tex]\frac{2}{3}[/tex].
The only line that has a gradient of [tex]\frac{2}{3}[/tex] is the line y = 2/3x - 13/ 3 ,this means that the line is parallel to Line K

y – 4 = –Two-thirds(x – 6) and passes through the point (−2, −2)?
Answer:
[tex]y=\frac{3}{2}x +1[/tex]
Step-by-step explanation:
We are given;
The equation of a line;
[tex]y-4 = -\frac{2}{3}(x-6)[/tex]
We are required to determine the equation of a line perpendicular to the above line and passing through (-2, -2).
We can get the gradient of a line when given its gradient and a point where it is passing through.In this case;We need to know that the product of gradient of two parallel lines is -1
Therefore, we can get the gradient of the unknown line;m₁× m₂ = -1
Thus;
m₂ = -1 ÷ -2/3
= 3/2
Thus, the gradient is 3/2 and the line passes through (-2,-2)
Thus, to get its equation, we take another point (x,y)
We get;
[tex]\frac{y+2}{x+2}= \frac{3}{2}[/tex]
Then;
[tex]2(y+2)=3(x+2\\2y + 4 = 3x + 6[/tex]
Combining the like terms,
[tex]2y=3x+2[/tex]
In the form of slope-intercept;
[tex]y=\frac{3}{2}x +1[/tex]
