y^2/81 - x^2/144=1
Answer:
A. m = 3/4 and m = -3/4Step-by-step explanation:
According to hyperbola form:
y²/a² - x²/b² = 1The slope of the asymptote is:
m = ± a/b, since the hyperbola is verticalFind the slope:
m = ± √81/√144= ± 9/12 = ± 3/4Correct choice is A
General equation is given be
[tex]\boxed{\sf \dfrac{y^2}{a^2}-\dfrac{x^2}{b^2}=1}[/tex]
On comparing
a^2=81=>a=9b^2=144=>b=12Now
[tex]\\ \rm\Rrightarrow m=\pm \dfrac{a}{b}=\pm\dfrac{9}{12}=\pm \dfrac{3}{4}[/tex]
Option A is correct

Maths log question please help- image attached
Answer:
a = 2 and b = -1.
Step-by-step explanation:
We want to show that the equation:
[tex]\displaystyle \log_{2} \left( y + 1\right) - 1 = 2\log_{2} x[/tex]
Can be rewritten as:
[tex]\displaystyle y = ax^2 + b[/tex]
Where a and b are integers.
Note that:
[tex]\displaystyle 1 = \log _{2} 2[/tex]
Hence:
[tex]\displaystyle \log_{2} \left( y + 1\right) - \log _2 2= 2\log_{2} x[/tex]
From logarithmic properties:
[tex]\displaystyle \log_2 \left(\frac{y+1}{2}\right) = 2\log_2 x[/tex]
Likewise:
[tex]\displaystyle \log_2 \left(\frac{y+1}{2}\right) = \log_2 x^2[/tex]
For the logs to be equivalent, the inner equations must be equivalent. Hence:
[tex]\displaystyle \frac{y+1}{2} = x^2[/tex]
Simplify:
[tex]\displaystyle y = 2x^2 - 1[/tex]
In conclusion, a = 2 and b = -1.

The functions f(x) = 2x and g(x) = 2-x+ 3 are combined using division to get function h(x).
Which represents the combined function?
Oh(x) = 22x + 3, x20
O h(x) = 22% -3, 20
Oh(x) = 22x + 3
X E all real numbers
Oh(x) = 22x – 3 x € all real numbers
Answer: the answer is not C
Step-by-step explanation:
The function that represents the combined function is h(x) = 2x/(2x + 3).
where x ∈ all real numbers.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
f(x) = 2x
g(x) = 2x + 3
Now,
h(x) = f(x) / g(x)
h(x) = 2x / (2x + 3)
Where x ∈ all real numbers
Thus,
The combined function is h(x) = 2x / (2x + 3)

In order to aerate and laser-grade a baseball field, a contractor charges $350, plus $25 per hour for a job. The equation C= 25h+350 describes the cost, c for a job that takes h hours. Rewrite the equation to isolate h.
Answer:
[tex]h=\dfrac{C-350}{25}[/tex]
Step-by-step explanation:
The equation that describes the cost is given as:
[tex]C=25h+350[/tex]
Where,
Contractor charges are $350 and per hour cost for a job $25.
Rewriting the equation below to isolate [tex]h[/tex]

Pam needed to give her gardener the approximate square footage of her backyard. With each step being about 2 feet, Pam steps it off and counts 20 steps long and 40 steps wide. About how many square feet is the backyard?
Answer:
3,200 sq ft
Step-by-step explanation:
20 X 2ft = 40ft
40 X 2ft = 80ft
40ft X 80ft = 3,200 sq ft
The number of square feet in the backyard will be 3,200 square feet
Since each step is being about 2 feet, which means the length will be :
20 steps
Length=20×2
Length=40 feet
40 steps
Length=40×2
Length=80 feet
Now let calculate How many square feet is the backyard will
Square feet=40 feet×80 feet
Square feet=3,200 square feet
Inconclusion The number of square feet in the backyard will be 3,200 square feet
