Answer:
x=-4
Step-by-step explanation:
The axis of symmetry is the x-value where the two “curves” of the parabola start at. For this parabola, the curves start at x=-4 and extend outward. So, the axis of symmetry is x=-4.
Answer:
x = -4
Step-by-step explanation:
The axis of symmetry is a vertical line thru the vertex. The vertex is (-4, 2).
So, the line of symmetry is x = -4
What is the differentiation of (sin3x-cos4x)(tan6x+sec8x)
Answer:
expanded:
y = sin(4x)*sin(4x)*cos(3x)
need to use the product rule and chain rule
look at individual derivatives, use chain rule
d/dx sin(4x) = 4cos(4x)
d/dx cos(3x) = -3sin(3x)
put it together using product rule
dy/dx = 4cos(4x)*sin(4x)*cos(3x) + 4cos(4x)*sin(4x)*cos(3x) - 3sin(3x)*sin(4x)*sin(4x)
simplify
dy/dx = 8cos(4x)*sin(4x)*cos(3x) - 3sin(3x)*sin2(4x)
answer is A.

A rectangular deck is 9 meters long by 7 meters wide. What is the length someone would walk
if they started at a corner and walked diagonally to the other corner?
Answer:
11.4 metres
Step-by-step explanation:
Use Pythagoras theorem for a right-angled triangle
a^2 + b^2 = c^2
if you cut the rectangle in half, it will become a right angled triangle.
a and b are two sides of the rectangle, while c is the diagonal or hypothenuse
so 9^2 + 7^2 = c^2
81 + 49 = c^2
c^ 2 = 130
square root 130 = c
you should get approximately 11.4 metres

Does the following graph represent a proportional or non-proportional relationship? Explain your reasoning.
Answer:
Non-proportional relationship
Step-by-step explanation:
Proportional relationships must pass through the origin. Otherwise, at [tex]x=0[/tex], we lose the constant of proportionality, and the y-value at [tex]x=0[/tex] becomes correlated only to the y-intercept.
The format for a proportional relationships is given by [tex]y=kx[/tex], where [tex]k[/tex] is some constant referred to as the constant of proportionality.

Answer:
Prime numbes
Step-by-step explanation:
Numbers whose only factors are 1 and itself are called prime numbers.
Such numbers have only two factors.
Examples are: 2, 3, 5, 7 ,9... etc.
Answer:
Prime numbers
Step-by-step explanation:
A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself.

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
We have,

A clothing store conducts a survey to determine customer satisfaction.
Which of these methods will produce the most representative sample of the population of store customers?
A. Survey all customers as they arrive at the store on a Monday.
B. Survey all customers who purchase shoes
C. Survey every 10th customer to enter the store.
D. Survey all customers who leave the store without making a purchase
Answer:
C
Step-by-step explanation:
This method is the best because it will survey the customers under one condition : every 10. If the store gets a lot of customers, then this should be easier to do. The rest are mostly dependent on what they do and that influences the survey. However, C makes it so that every 10 people are surveyed.
Answer:
A isnt the correct answer. B doesnt seem reasonable because its one specific item. D means they arent exactly a customer since they didnt buy anything therefore the answer would be C

Karen and Ricardo are 279 miles apart driving towards each on the same route. Karen drives at a speed of 59 miles per hour and Ricardo drives at a speed of 65 miles per hour. In how many hours will they meet?
Answer:
They will meet in 2.25 hours or 2 hours 15 minutes
Step-by-step explanation:
At any point in time;
distance = speed * time
Let the number of hours at which they meet be x
In x hours, the distance traveled by Karen will be 59 * x = 59x miles
In same x hours, the distance traveled by Ricardo will be 65 * x = 65x miles
Since they are traveling in opposite directions, the distance traveled at that time by Karen will be less than what Ricardo has traveled since he is traveling at a greater speed
However, the sum of whatever they have traveled will be equal to the distance between them
thus;
59x + 65x = 279
124x = 279
x = 279/124
x = 2.25 hours

What is the inverse of the function g(x)=x^3/8+16?
The inverse of the function for [tex]g^{}(x) = \frac{x^{3} }{8}+16[/tex] is [tex]g^{-1}(x)=2\sqrt[3]{x-6}[/tex]
What is inverse of the function?"The inverse function of a function f (also called the inverse of f ) is a function that undoes the operation of f. The inverse of f exists if and only if f is bijective, and if it exists, is denoted by [tex]f^{-1}[/tex]."
We have
[tex]g^{}(x) = \frac{x^{3} }{8}+16[/tex]
Replace g(x) with y
[tex]y =[/tex] [tex]\frac{x^{3} }{8}+16[/tex]
Interchange the variables
[tex]x= \frac{y^{3} }{8}+16[/tex]
Rewrite the equation as
[tex]\frac{y^{3} }{8}+16= x[/tex]
⇒[tex]\frac{y^{3} }{8}= x-16[/tex]
Multiply both sides of the equation by 8
[tex]8.\frac{y^{3} }{8}=8(x-16)[/tex]
⇒[tex]{y^{3} }=8(x-16)[/tex]
⇒[tex]{y^{3} }=8x-128[/tex]
⇒[tex]{y} }=\sqrt[3]{8x-128}[/tex]
⇒[tex]{y} }=2\sqrt[3]{x-6}[/tex]
Replace y with [tex]g^{-1}(x)[/tex]
⇒[tex]g^{-1}(x)=2\sqrt[3]{x-6}[/tex]
Hence, The inverse of the function for [tex]g^{}(x) = \frac{x^{3} }{8}+16[/tex] is [tex]g^{-1}(x)=2\sqrt[3]{x-6}[/tex]

Answer:

Step-by-step explanation:
Sequence has been given as,
[tex]a_n=\frac{n^3+3n}{n^2-6n}[/tex]
[tex]\lim_{n \to \infty}\frac{n^3+3n}{n^2-6n}[/tex]
[tex]=\lim_{n \to \infty}\frac{\frac{n^3+3n}{n^3} }{\frac{n^2-6n}{n^3} }[/tex]
[tex]=\lim_{n \to \infty}\frac{1+\frac{3}{n^2}}{\frac{1}{n}-\frac{6}{n^2} }[/tex]

Write the quadratic equation in standard form.
Answer:
2x² + 6x + 15 = 0
Step-by-step explanation:
Given quadratic equation is,
-2x² - 6x = 15
We have to convert this equation in the standard form of the quadratic equation,
ax² + bx + c = 0
(-2x² - 6x) = 15
-2x² - 6x - 15 = 0
2x² + 6x + 15 = 0

OD. y= cos(2x)
(Ignore the answer selected I don’t know it it’s correct)
Using translation concepts, the function whose graph is plotted is given by:
y = 0.5cos(x).
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
In this problem, the y-intercept is different of zero, hence it is a cosine function. The amplitude is of 0.5, hence the function is multiplied by 0.5, that is, y = 0.5cos(x), which means that option C is correct.
