What is a quadratic equation?A basic quadratic equation, or a second-order polynomial equation with a single variable, is represented by the equation x : ax² + bx + c = 0, where a≠0 for the variable x. As it is a second-order polynomial equation, which is ensured by the algebraic fundamental theorem, it must have at least one solution.
The standard equation for a hyperbola centered at the origin is:
(x²)/(a²) - (y²)/(b²) = 1
where "a" and "b" are the lengths of the transverse and conjugate axes, respectively. To find the value of "b" for the given hyperbola equation, we need to first rewrite it in the standard form.
(x²)/(24²) - (y²)/(b²) = 1
Multiplying both sides by (24²)(b²), we get:
b²(x²) - (24²)(y²) = (24²)(b²)
Dividing both sides by (24²), we get:
b²(x²)/(24²) - y² = b²
Comparing this with the standard equation, we can see that a = 24 and b is the square root of the constant term, which is b² = 576. Therefore, b = 24.
However, the given directrix of x = 576/26 is not consistent with the equation of the hyperbola. The directrix for a hyperbola with center at the origin and transverse axis along the x-axis is given by x = a²/b. Using the value of a = 24, we can find the directrix as:
x = (24²)/b
Setting this equal to 576/26, we get:
(24²)/b = 576/26
Solving for b, we get:
b = 16
Therefore, the correct answer is (B) 16.

Answer:
h ≤ -7/2
Step-by-step explanation:
This is what is known as a "2-step" problem.
The first step is to "isolate the variable term" by adding the opposite of the term on the left that does not have the variable in it. That is, we want to add -4 to both sides of the inequality.
4 -4 +2h ≤ -3 -4 . . . . add -4 to both sides
2h ≤ -7 . . . . . . . . . . variable term isolated
Now, we want to get rid of the coefficient of the variable (make it be 1), so we use the multiplicative inverse. That is, we multiply both sides of the inequality by 1/2, the reciprocal of the coefficient.
(1/2)(2h) ≤ (1/2)(-7) . . . . . multiply both sides by 1/2
h ≤ -7/2 . . . . the solution
__
For an inequality, multiplying or dividing by a negative number causes the direction of the comparison to be reversed. (Here, our multiplier was 1/2, not negative, so no such reversal was required.)
Example:
1 < 2
-1 > -2 . . . . . both sides multiplied (or divided) by -1
_____
Additional comment
As when solving equations, you must do the same thing to both sides of the inequality.

Convert the following to standard form, then write
the quadratic term, the linear term, and the constant
term in the space provided:
f(x) = (x + 3)2
Answer:
[tex]f(x)=x^2+6x+9[/tex]
Step-by-step explanation:
We are required to represent the expression given in the standard form to the quadratic form
Given
[tex]f(x) = (x + 3)^2[/tex]
let us square the given expression
f(x)=(x+3)(x+3)
open brackets
[tex]f(x)=x^2+3x+3x+9[/tex]
sum the similar terms
[tex]f(x)=x^2+6x+9[/tex]
Match each function with its graph (2 points)
f(1) = 1 (1 + 1)(x - 2)
f(x) = -13 +372
Il
f(1) = -1 (1 - 1) (x + 2)
f (2) = + 3x2

In a biomedical research study, it was determined that the survival time, in weeks, of an animal subjected to a certain exposure of gamma radiation has a gamma distribution with α= 5 and β=10.
a. What is the mean survival time of a randomly selected animal of the type used in the experiment?
b. What is the standard deviation of survival time?
c. What is the probability that an animal survives more than 30 weeks?
Answer:
Step-by-step explanation:
From the given information:
Let X be the random variable;
The mean survival time is E(X):
E(X) = μ
E(X) = ∝β
E(X) = 5 × 10
E(X) = 50
To find the standard deviation, we must first determine the variance:
[tex]V(X) = \sigma ^2[/tex]
[tex]V(X) = \alpha \beta ^2[/tex]
[tex]V(X) = 5 \times (10)^2[/tex]
[tex]V(X) = 5 \times 100[/tex]
[tex]V(X) = 500[/tex]
The standard deviation is:
[tex]\sigma =\sqrt{V(X)}[/tex]
[tex]\sigma =\sqrt{500}[/tex]
[tex]\sigma =22.361[/tex]
The standard deviation of survival time = 22.361
(c)
P(X>30) = 1 - P(X ≤ 30)
[tex]= 1 - \int \limits ^{30}_{0} \ f(x) \ dx[/tex]
[tex]= 1 - \int \limits ^{30}_{0} \dfrac{1}{\beta^{\alpha} \Gamma \alpha }x^{a-1} e ^{-x/\beta } \ dx[/tex]
[tex]= 1 - \int \limits ^{30}_{0} \dfrac{1}{\beta^{\alpha} \Gamma (5)}x^{5-1} e ^{-x/10 } \ dx --- (1)[/tex]
So, if:
[tex]y = \dfrac{x}{10}[/tex]
[tex]dy = \dfrac{dx}{10}[/tex]
10dy = dx
and limits of y are 0 and 3.
because;
for x = 0
[tex]y = \dfrac{0}{\beta}[/tex]
y = 0
For x = 30
[tex]y = \dfrac{30}{10}[/tex]
y = 10
From (1);
[tex]P(X> 30) = 1 - \int \limits ^{30}_{0} \dfrac{1}{\beta^{\alpha} \Gamma (5)}x^{5-1} e ^{-x/10 } \ dx[/tex]
[tex]P(X> 30) = 1 - \int \limits ^{3}_{0} \dfrac{(10y)^4}{10^{5} \Gamma (5)}e ^{-y } \ dy[/tex] since y = x/β
[tex]P(X> 30) = 1 - \int \limits ^{3}_{0} \dfrac{10^4 y^4 \ e^{-y} }{10^{4} \Gamma (5)} \ dy[/tex]
[tex]P(X> 30) = 1 - \int \limits ^{3}_{0} \dfrac{y^4 \ e^{-y} }{ \Gamma (5)} \ dy[/tex]
Since;
[tex]F(a, \alpha )= \int \limits ^a_0 \dfrac{y^{a-1}e^{-y}}{\Gamma (\alpha )} dy[/tex]
Then;
P(X> 30) = 1 - F(3,5)
From the table of incomplete gamma function;
P(X > 30) = 1 - 0.185
P(X > 30) = 0.815
Thus, the probability that an animal survives more than 30 weeks is 0.815
a)The mean survival time of a randomly selected animal of the type used in the experiment is 50.
b)Standard deviation of survival time is 22.36
What is the standard deviation?The standard deviation of a random variable, sample, statistical population, data set, or probability distribution is the square root of its variance.
Suppose x is the random variable.
It is given that α= 5 and β=10.
So, the mean survival E(x)=α β
The mean survival E(x) =5*10
The mean survival E(x) =50
We know that Variance =α β²
So, Variance = 5*10²
Variance =500
We know that standard deviation σ = √Variance
σ = √500
σ = 22.36
Therefore, a)the mean survival time of a randomly selected animal of the type used in the experiment is 50.
b)Standard deviation of survival time is 22.36

raised for 60 attendees?
9514 1404 393
Answer:
$1200

60 attendees is 12 times 5 attendees, so we expect the amount raised to be 12 times $100.
$1200 will be raised for 60 attendees.
Percentages are numerators of the fractions with denominator
9514 1404 393
Answer:
100
Step-by-step explanation:
The % symbol can be thought of as a shorthand way to write /100. That is, the symbol can be replaced by /100 wherever you see it, and vice versa:
23% = 23/100
23 is the numerator of the fraction with denominator 100.
