On which interval is y = sin(x) strictly increasing?
(Negative pi, negative StartFraction pi Over 2 EndFraction)
(0, pi)
(StartFraction pi Over 2 EndFraction, StartFraction 3 pi Over 2 EndFraction)
(0, StartFraction pi Over 2 EndFraction)
Answer:
The function is strictly increasing on (0, π/2)
Step-by-step explanation:
We are given the function;
y = sin x
Let's find the derivative;
dy/dx = cos x
Now, Cos 0 = 1
Cos (π/4) = 1/√2
Cos (π/2) = 0
From the above, we can see that as x approaches 0 from (π/2), the value of (cos x) approaches 1. This means it's increasing from 0 to 1.
Thus, the function is strictly increasing on the interval (0, π/2)
Answer:
D. (0, pi/2)
Step-by-step explanation:
If you graph y=sin(X) (I used desmos) then you find that the graph is increasing from 0 to pi/2 :)

Jose earned 45 points in a video game. He lost 40 points, earned 80 points, then lost 25 more points. Enter and evaluate an expression to find his final score in the video game.
im confused any help?
Answer:
60 points
Step-by-step explanation:
Every time he earns points we add.
Every time he loses points we subtract.
We can write an equation to resemble the problem and simplify.
45 - 40 + 80 - 25
5 + 80 - 25
85 - 25
60

Please help with these angles!!!
Answer:
23. y = 47
Step-by-step explanation:
40 + 5x =180 (angls on a straight line add up to 180 degrees)
5x=140 (minus 40 from both sides)
x = 28 (divide both sides by 5)
3y - 1 = 140
3y =141 (add 1 to both sides)
y = 47 (divide both sides by 3)
Answer:
y=47

Step-by-step explanation:
A cylindrical tube has a length of 14.4cm and a radius of 1.5cm and is filled with a colorless gas. If the density of the gas is known to be 0.00123g/cm 3 , what is the mass of the gas in the tube in mg?
Answer:
0.125214 gStep-by-step explanation:
we know that density is given as
density=mass/volume
the volume of the cylinder
v= πr^2h
v=3.142*1.5^2*14.4
v=3.142*2.25*14.4
v=101.8cm^3
Given that density =0.00123g/cm^3
mass= density*volume
masss= 0.00123*101.8
mass= 0.125214 g

Write the equation of the line that is parallel to y = 9x+ 4 and crosses the y-axis at -3.
9514 1404 393
Answer:
y = 9x -3
Step-by-step explanation:
The given line is in "slope-intercept form"
y = mx + b
where m is the slope and b is the y-intercept (where it crosses the y-axis).
In your given line, we have ...
m = 9, b = 4
__
A parallel line will have the same slope, so we know that the line you want has m = 9. You are told to make the line cross the y-axis at -3, so that makes b = -3. Putting these values into the slope-intercept form gives the desired equation:
y = 9x -3
_____
The attached graph is intended to show the lines are parallel and the equation given here meets the requirement for a crossing of the y-axis at -3. The vertical and horizontal scales are different in order to better show these things.

If f(x) = 0.41x is a function that represents the cost to mail
x number of letters, what is a reasonable domain for f?
O all real numbers
o all real numbers greater than 0
O the set of all whole numbers
o the set of all integers
Answer:
B
Step-by-step explanation:
The domain of the function 'f' represents the set of all whole numbers.
What is a function?A function is a relation between two sets. One set is called domain of the function and the other one is called range range of the function.
Given function is: f(x) = 0.41x.
f(x) represents the cost of mail.
Here, x represents the number of letters in the mail.
It can't be real numbers because, real numbers consist of negative numbers, fractions, etc.
It can not be integers, real numbers consist of negative numbers.
Therefore, the domain of must be all whole numbers.

Answer:
y = x - 6y = -x + 5y = x - 5Step-by-step explanation:
Slope - intercept formula: y = mx + b, where m- slope, b- y-intercept
1. Points are:
(2, -4) and (4, -2)Slope is:
m = (y2 - y1)/(x2 - x1) m = (-2 - (-4))/(4 - 2) = 2/2 = 1y-intercept is - 6 as per graph
Then the formula is
y = x - 62. Points are:
(0,5 ) and (4, 1)Slope is:
m = (1 - 5)/(4 - 0) = -4/4 = -1y-intercept is 5 as per point
Then the formula is
y = -x + 53. Points are:
(-3, 1), (-1, -3)Slope is
m = (3 - 1)/(-1 -(-3)) = 2/2 = 1y-intercept is -5 as per graph
Then the formula is
y = x - 5For the figure, which of the following is true? I. m∠1+m∠2=m∠6+m∠5 II. m∠1+m∠3=m∠6+m∠4 III. m∠1+m∠3+m∠6=m∠2+m∠4+m∠5 A. I only B. I and II only C. II only D.

Which of the following regular polygons circumscribed about a circle provides the best estimate for the area of that circle?
dodecagon
decagon
20-gon
11-gon
Answer:
The correct option is;
20-gon
Step-by-step explanation:
The area, A, of a regular polygon is given as follows;
[tex]A = \dfrac{n \times s \times a}{2} = \dfrac{P_p \times a}{2}[/tex]
Where;
n = The number of sides
s = The length of one side of the polygon
a = The apothem
[tex]P_p[/tex] = The perimeter of the polygon
Where
The area of a circle, A[tex]_c[/tex] = π×r² = π × r × r = 2× π × r × r/2 = P/2 × r
Given that the apothem, a, of a 20-gon circumscribed about a circle is approximately the length of the radius of the circle, and the perimeter of the 20-gon is approximately the perimeter (circumference) of the circle, the area of the 20-gon circumscribed about a circle provides the best estimate for the area of the circle.

Answer:
$46.20
Step-by-step explanation:
Since it was discounted 30%, this means that 30% of the original price was taken off. To find the price remaining after the discount, you subtract 30% from 100% which would give you 70%. Then multiply $66.00 and 0.7 and you will get $46.20
