By looking the given options, we can say that some of them are following pythagorean identities and pythagorean identities are
sin^2(x) + cos^2(x) =1, sec^2(x)-tan^2(x) =1,csc^2(x) -cot^2(x)=1
So out the four options, option a and option c are following pythagorean identity and option b and option d are not following pythagorean identity. And we have to find those options which are not identities .
So the correct options are
b) sec^{2} x+csc^{2} x=1 \ d) tan^{2} x + sec^{2} x =1
Answer:
Slope = 6.000/2.000 = 3.000
x-intercept = 10/3 = 3.33333
y-intercept = -10/1 = -10.00000
Step-by-step explanation:
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -10.000 and for x=2.000, the value of y is -4.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -4.000 - (-10.000) = 6.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Answer:
50z + 17
Step-by-step explanation:
-5(-10z + -4) +-3
distribute
= 50z +20 -3
=50z + 17
Answer:

Step-by-step explanation:
Given:
Number of questions (N) = 16
Number of easy questions (E) = 8
Number of medium-hard questions (M) = 5
Number of hard questions (H) = 3
Now, the probability of getting the first question as easy question is given as:

Now, probability of getting the second question as easy question is given as:

Now, probability that the first two contestants will get easy questions is given by the product of
. So,

Therefore, the probability that the first two contestants will get easy questions is 
The arc length of the circle exists 846.65922 cm.

How to estimate the central angle in degree? </h3>
A unit circle by definition contains a radius of 1 unit.
We have to estimate the length of the arc subtended by an angle of
radians.
arc length = radius
angle
s = r
Where s be the arc length
r be the radius of the circle
be the angle measured in radians
arc length = 77cm
arc length = 77
7(3.14) / 2
arc length = 846.65922 cm
Therefore, the arc length of the circle exists 846.65922 cm.
