What is the maximum of f(x)=sin(x)
Answers
Answer:
1
Step-by-step explanation:
The maximum of f(x) = sin(x) is 1. The sine function has a range of -1 ≤ sin(x) ≤ 1. The sine function oscillates between -1 and 1, reaching a maximum of 1 when x = π/2 and a minimum of -1 when x = -π/2. If you look at a graph of
y = sin(x) you can see this.

Answer:
Now in the question we are told to choose our on function so for this solution the function which we will use is
\(D = 18t + 2t^2\)
In this function D is the distance in meters which is been traveled at a given time t in seconds
Now it we want to obtain the distance traveled in t = 13 s
This means that t = 13 s is the input of the function
So we have
\(D = 18 (13) + 2* (13)^2\)
=> \(D = 572 \ m\)
So D is a function of t
Now let consider one of the functions given in the question
The circumference of a circle is a function of diameter.
Generally the circumference of a circle is mathematically represented as
\(C = \pi d\)
Here \(\pi\) is constant with value \(\pi = 3.142\)and d is the diameter (in meters) of the circle so
if for example d = 0.2 m , here the diameter is the input
Then the circumference is
\(C = 3.142 * 0.2\)
\(C = 0.6284 \ m \)

Kevin takes classes at both Westside college and Pinewood college at Westside class fees are $98 per credit hour and Pinewood they are $115 per credit hour. Karen is taking combined total of 18 credit hours at the two schools. Suppose that she's taking W credit hours at Westside. Write an expression for the combined total dollar amount that she paid for the class fees
Answers
Answer:
y = 98(w) + 115(18 - w)
Step-by-step explanation:
The expression that represents how much Kevin spends for classes at both schools : (#credits at Westside)($98) + (#credits at pinewood)($115). If he takes all credits at Westside this is 18(98) + 0, which would be the lowest cost it could be, if he takes all credits at Pinewood this would be 0 + (18)(115) which would be the maximum Bob could pay for 18 credits. If y is the total cost of is courses, then y = 98(w) + 115(18 - w). Using the distributive property, this can be simplified.

Round the number to the place of the underlined digit. 4.3186 (the underline number is one). The rounded number is?
Answers
Let's begin by listing out the information given to us:
The number is 4.3186
We are to round the number to the place of the underlined digit
The underlined number is 1 (the hundredth place value)
If the number after 1 is less than 5, we round down & if the number is 5 or more, we round up. The number after 1 is 8 (greater than 5). We have:
\(4.3186\approx4.32\)Hence, the rounded number is 4.32

Answers
The graph of g(x) = 4x, is the translation of f(x) by subtracting 3.5 units, 2 of 3.
What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
The cost can be modeled by the function f(x)=4x+3.5, where x represents the number of games bowled.
As per the given question, the required solution would be as:
g(x) = 4x , is the translation of f(x) by subtracting 3.5 units, 2 of 3.
The graph of g(x) would be identical to the graph of f(x), but shifted 3.5 units downward, 3 of 3.
This is because the flat fee for the rental of bowling shoes is not present in the function g(x), so the y-intercept of the graph would be at (0,-3.5) instead of (0,0) in f(x) function.
The slope and the shape of the function will remain the same.

For the inequality y+4x≤x2+2, where is the graph shaded and is the curve solid or dotted?
Answers
Answer:
B
Step-by-step explanation:
first for the easy one : the curve line is dotted, if the line points are NOT part of the solution. and it is solid, if the points are included.
you know what the curve line indicates ? it indicates the points for which there is equality.
so, if there is a ">=" or "<=" relation, then that includes equality, and the curve is solid.
if there is only a true inequality ("<", ">"), then the curve is dotted, as the equality is not included.
so, I how this is now really clear.
in our case here (I suspect it really looks like this)
y + 4x <= x² + 2
we have a "<=" sign, so, the curve is ..., well ? ... well ? ...
well ? ... well ? ... solid !
and we still treat inequalities as much as possible as regular equalities.
so,
y <= x² - 4x + 2 (after subtracting 4x from both sides).
and now you see it, right ?
all y values that are smaller or equal to the quadratic expression.
SMALLER ! so, BELOW the curve (as the smaller y values are represented by the lower part of the y-axis).
