Answer:
Option: a is correct
a) y= -cos x
Step-by-step explanation:
We could clearly see that the graph of the function passes through a point on the y-axis which is :
(0,-1)
i.e. when x=0 the value of the function y= -1
So we will check in each of the following options by putting x=0 and check whether y= -1 or not.
b)
y=sin x
on putting x=0 we get:
y=sin 0=0≠ -1.
Hence, option b is incorrect.
c)
y= cos x.
we put x=0
y= cos 0=1≠ -1.
Hence, option c) is incorrect.
d)
y= -sin x
we put x=0 to obtain:
y= -sin 0=0≠ -1.
Hence, option d is incorrect.
Hence we are left with option a i.e.
The graph represents the function:
y= -cos x. (Hence, option a is correct)
( Also it satisfies at x=0
since, y= -cos 0= -1 )
My bad nobody is correct because the answer would equal 5/24
5/24 is in simplest form
The fraction 5/24 is alread in the simplest form, so it isn't possible to reduce it any further.
This is a PROPER FRACTION once the absolute value of the top number or numerator (5) is smaller than the absolute value of the bottom number or denomintor (24).
The fraction 5/24 is equal to 5÷24 and can also be expressed in decimal form as 0.208333.
Answer:
(9,3)
Step-by-step explanation:
We have been given an equation of a line and we are asked to find the point that lies on our given line.
Since we know that point-slope form equation of a line is: , where,
m = The slope of the line.
= The coordinates of given point on the line.
Since our given equation is in point-slope form, so x-coordinate of our given point is 9 and y-coordinate of our given point is 3.
Therefore, point (9,3) lies on the line described by our given equation.
Answer:
percent means <u>per hundred </u>
Between the 100 squares, 60 of them are shaded
so you do 60/100
it's kind of like correcting tests, you have 100 questions, you got 80 of them right so its going to be 80/100
when you calculate percentage, you do the fraction x 100
so it's 60/100 = 0.6 x100 = 60%
hope that answers your question

Step-by-step explanation:
45 + a = 180 [ linear pair ]
a = 180 - 45
a = 135
