Consider function f.
Which statement is true about function f?
A.
The function is continuous.
B.
The domain is all real numbers.
C.
The function is increasing over its entire domain.
D.
As x approaches positive infinity, approaches positive infinity.
Answers
The statement B is as x approaches positive infinity f(x) approaches positive infinity is true.
What is the definition of the limit?
A point or level beyond which something does not or may not extend or pass.
We have to check for continuity by evaluating 2ˣ and -x² - 4x + 1
at the breakpoint x = 0
2⁰ is 1 and -x² - 4x + 1 is also 1,
So these two functions approach the same value as x approaches 0.
Now do the same thing with
-x² - 4x + 1 and (1/2)x + 3 at x = 2;
The first comes out to -11 and the second to 4.
Thus, this function is not continuous at x = 2.
We must reject statement A.
for D we have as x increases without bound,
(1/2)x + 3
also increases without bound.
Therefore the statement D is true statement.
Statement C is False,
because the quadratic has a maximum -x² - 4x + 1 has a maximum at
x = -b/[2a],
x = -(-4) / [-2],
x = -2
There are no limitations on the values of the input, x.
A is also a false negative number are in real numbers.
Therefore, the statement B is as x approaches positive infinity f(x) approaches positive infinity is true.

The side lengths of a 30-60-90 triangle are in the ratio 1: √3:2. What is
cos 60°?
Answers
The value of cos60° is 1/2.
What is a 30-60-90 triangle?It is a triangle with constant angles of 30, 60, and 90. This triangle is always a right triangle, as one of the angles is 90 degrees. Thus, a right-angled triangle is formed by these angles. Additionally, the right angle is equal to the sum of two acute angles, which will have a 1: 2 or 2: 1 ratio.
We know,
For a 30-60-90 triangle, the sides opposite to 30° is a, the side opposite to 60° is √3a and the side opposite to 90° is 2a.
Therefore,
If a = 1,
The sides are where,
perpendicular = 1
Base = √3
Hypotenuse = 2
We know cosΦ = Base/ Hypotenuse
But in the case of cos60°, we have to take base as 1 and hypotenuse as 2, that is the angle has to be at base.
Base = 1
Hypotenuse = 2
Therefore,
cos60° = Base/ Hypotenuse
cos60° = 1/2
Therefore, the cos60° = 1/2.

c. Next month, Jay plans to order 7 movies.
d. This month, Jay's total bill is $ 78.50.
What will be his total bill for the month?
How many movies did he order this month?
Answers
Answer:
y=f+3.5x
Step-by-step explanation:
Let the total bill be y
and let the number of movies be x
let the flat fee be f
given that he pays $3.5 per movie
and his total bill is $54
The expression is given bellow for his total bill
y=f+3.5x
For 5 movies his total bill is $54
54=f+3.5(5)
54=f+17.5
54-17.5=f
f=36.5
Therefore the flat fee is $36.5

(A) The rate of making coffee by coffee maker is 6 mL/second.
(B) The rate of making juice by juice maker is 8 mL/second.
(C) Juice is being made at a faster rate.
What is ratio?Ratio basically compares quantities, that means it show value of one quantity with respect to other quantity.
If a and b are two values, their ratio will be a:b,
Given that,
The rate of coffee made by coffee maker is represented by,
y = 6x (1)
Here, y represents the amount of coffee in mL and x represents the time passed in seconds.
Also, The rate of juice made by juice make can be represented by the given table as,
k = 8h (2)
Here, k represents the amount of juice in mL and h represents the time passed in seconds.
(A)
To find the rate of making coffee, solve the equation (1),
y = 6x
⇒ y/x = 6 mL/second
The rate of making coffee by coffee maker is 6 mL/second.
(B)
To find the rate of making juice, solve the equation (2),
k = 8h
⇒ k/h = 8 mL/second
The rate of making juice by juice maker is 8 mL/second.
(C)
Since, the juice is made at the rate of 8 mL/second and the coffee is made at the rate of 6 mL/second.
Therefore, juice is being made at a faster rate.
