Find the equation of the hyperbola with the following properties. Express your answer in standard form.Foci at (7, 0) and (7, 10)Asymptotes ofy -5 = t;( -7
Answers
Answer:
\(\frac{(y-5)^2}{16}-\frac{(x-7)^2}{9}=1\)
Explanation:
The standard form of an hyperbola is:
\(\frac{(y-k)^2}{a^2}-\frac{(x-h)^2}{b^2}=1\)Where (h, k) are the coordinates of the center.
We are given the asyptotes and the foci.
The foci are (7, 0) and (7, 10)
The y value of the center of the parabola is midway from the two foci. Then, the y-coordinate of the center is 5
The coordinated of the center are (7, 5)
Now, we can use that the form of the asymptotes are:
\(y=k\pm\frac{a}{b}(x-h)\)We have:
\(y-5=\frac{4}{3}(x-7)\)Then:
\(\frac{a}{b}=\frac{4}{3}\)a = 4
b = 3

Answer:
The line y = -2 - 4x has slope -4.
Slopes of perpendicular lines have product -1, so the slope of a line perpendicular to a line with slope -4 will be 1/4.
Slopes of parallel lines are the same, so the slope of a line parallel to a line with slope -4 will be -4.
Answer:
\(\frac{1}{4}\) and - 4
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
y = - 2 - 4x , or
y = - 4x - 2 ← in slope- intercept form
with slope m = - 4
given a line with slope m then the slope of a line perpendicular to it is
\(m_{perpendicular}\) = - \(\frac{1}{m}\) = - \(\frac{1}{-4}\) = \(\frac{1}{4}\)
slope of perpendicular line is \(\frac{1}{4}\)
• Parallel lines have equal slopes , then
slope of parallel line is - 4

Solve the inequality and graph, if possible
Answers
For the given inequality 3 + (4/3)x + 7 ≥ -89 the value of x ≥ (-297 / 4).
Graph of the given inequality is attached.
As given in the question,
For the given inequality we have:
3 + (4/3)x + 7 ≥ -89
Simplify the given inequality by taking all like terms together we have,
(4/3)x + 10 ≥ -89
Subtract 10 from both the side we get,
(4/3)x + 10 -10 ≥ -89 -10
⇒ (4/3)x ≥ -99
Multiply both the side by (3/4) we get,
x ≥ -99 × (3/4)
⇒ x ≥ (-297 /4)
Graph of the given 3 + (4/3)x + 7 ≥ -89 is attached .

Suppose you deposit $2,000 in a savings account that pays interest at an annual rate of 5%. If no money is added or withdrawn from the account, answer the following questions.
a. How much will be in the account after 4 years?
b. How much will be in the account after 16 years?
c. How many years will it take for the account to contain $2,500?
d. How many years will it take for the account to contain $3,000?
years.
d. For the account to contain $3,000, it will take years
(Type a whole number.)
Answers
Answer:
a. After 4 years, the amount in the account can be found by using the formula for simple interest:
A = P * (1 + r * t), where P is the initial deposit, r is the annual interest rate as a decimal, and t is the number of years.
Plugging in the values, we get:
A = $2,000 * (1 + 0.05 * 4) = $2,000 * 1.2 = $2,400
So after 4 years, there will be $2,400 in the account.
b. After 16 years, the amount in the account can be found using the same formula:
A = $2,000 * (1 + 0.05 * 16) = $2,000 * 1.8 = $3,600
So after 16 years, there will be $3,600 in the account.
c. To find the number of years it will take for the account to contain $2,500, we can use the formula:
t = (A - P) / (P * r), where A is the desired amount.
Plugging in the values, we get:
t = ($2,500 - $2,000) / ($2,000 * 0.05) = ($500) / ($100) = 5 years
So it will take 5 years for the account to contain $2,500.
d. To find the number of years it will take for the account to contain $3,000, we can use the same formula:
t = ($3,000 - $2,000) / ($2,000 * 0.05) = ($1,000) / ($100) = 10 years
So it will take 10 years for the account to contain $3,000.

find equations of the line that is parallel to the z-axis and passes through the midpoint between the two points (0, −2, 7) and (−2, 3, 5). (enter your answers as a comma-separated list of equations.)
Answers
The equations of the line parallel to the z-axis and passing through the midpoint between the two given points are x = -1, y = 0.5, and z = t, where t represents the distance along the z-axis.
Since the line is parallel to the z-axis, its direction vector will be (0, 0, 1). Now, let's find the midpoint between the two given points:
Midpoint = ((0 + (-2))/2, (-2 + 3)/2, (7 + 5)/2)
= (-1, 0.5, 6)
Therefore, the line parallel to the z-axis and passing through the midpoint (-1, 0.5, 6) can be represented by the following set of parametric equations:
x = -1 (remains constant)
y = 0.5 (remains constant)
z = t (where t is a parameter representing the distance along the z-axis)
In Cartesian form, the equation of the line can be written as:
x = -1
y = 0.5
z = t

a factorial design involves a) manipulating two or more independent variables. b) an inability to specify the overall effect of an independent variable. c) having multiple dependent measures. d) all of these
Answers
The correct answer is
(a) manipulating two or more independent variables.
A factorial plan could be a sort of test plan utilized in investigating to examine the impacts of two or more free factors on a subordinate variable.
In a factorial plan, analysts control each free variable over different levels to watch the one-of-a-kind impacts of each free variable and how they connected with each other to impact the subordinate variable.
For case, in a ponder examining the impacts of two autonomous factors (e.g., temperature and mugginess) on a subordinate variable (e.g., plant development), analysts may control the temperature at three distinctive levels (moo, medium, and tall) and mugginess at two diverse levels (moo and tall) to watch how these components influence plant development individually and in combination.
Therefore, the correct answer is (a) manipulating two or more independent variables.

Light sample A has a frequency of 4.30 ×1015 Hz and light sample B has a frequency of 8.70×1018 Hz. Based on frequency, which set gives the most correct description of the types of light for samples A and B respectively?
Answers
1) The wavelength of A is equal to 6.98 × \(10^{-8}\)meters
2) The wavelength of B is equal to 3.45 × \(10^{-11}\) meters
Since we know that the wavelength = speed of light / frequency
The speed of light is 3.00 × \(10^8\) meters per second.
For light sample A with a frequency of 4.30 × 10^15 Hz can be calculated as;
wavelength of A = (3.00 × \(10^8\) m/s) / (4.30 × 10^15 Hz)
wavelength of A = 6.98 × \(10^{-8}\) meters
For light sample B with a frequency of 8.70 × \(10^18\) Hz can be calculated as;
wavelength of B = (3.00 × \(10^8\) m/s) / (8.70 ×\(10^18\) Hz)
wavelength of B = 3.45 × \(10^{-11}\) meters

To determine the number of ways to arrange items when order does matter but the items are not replaced is done with a permutation. True or false
Answers
ANSWER
True
EXPLANATION
When the order matters, the number of ways to arrange items is determined with a permutation. This way, sets of items with the same items but in different order are counted as different sets. For example, (blue, red, green) is not the same as (green, red, blue).
On the other hand, when order does not matter, the number of ways to arrange items is determined with a combination. This way, sets with the same items are counted as the same set. In the previous example, both sets have the same combination of colors, so they are counted as the same set.
Hence, it is true that when the order does matter, the number of ways to arrange items is determined with a permutation.

The two equations that represent a shift of the graph are y=(x-12)³ and y=(x+8)³.
What is an equation?
Variable terms are frequently used in complex algorithms to reconcile two opposing claims. Academic statements known as equations are used to express the equivalence of different academic quantities. Rather than using a specific algorithm to divide 12 into two parts and assess the data obtained from y + 7, normalization in this case leads to b + 7.
The two equations describe a shift of the graph of the parent equation on the coordinate plane towards the right.

Angles p and q are complementary. p is four times the size of q. what is the size of q.
Answers
Angles p and q are complementary, which means that their sum is equal to 90 degrees. Let's assume the size of angle q is x degrees. Since p is four times the size of q, we can write the equation p = 4q.
To find the size of q, we need to substitute the value of p in terms of q into the equation for the sum of the angles: p + q = 90.
Substituting 4q for p, we get:
4q + q = 90
Combining like terms:
5q = 90
To solve for q, we divide both sides of the equation by 5:
q = 90/5
Simplifying:
q = 18
Therefore, the size of angle q is 18 degrees.
when angles p and q are complementary and p is four times the size of q, the size of angle q is 18 degrees.
