Answer:
So for his mark will be in between 82 to 130 for C grade
Step-by-step explanation:
We have given that for C grade the minimum average mark should be 77 and maximum average mark should be 85
There are 6 subjects
So total minimum mark = 6×77 =462
And total maximum mark = 85×6 =510
He has five grades as 74,78,76,67,85
So sum of five grades = 74+78+76+67+85=380
Let he get x marks in 6th
So for minimum mark in 6th grade x+380 = 462
x = 462-380=82
For maximum mark x+380=510
x = 510-380 =130
So for his mark will be in between 82 to 130 for C grade
Every equilateral triangle is also anisosceles triangle, so any two sides that are equal have equal opposite angles. Therefore, since all three sides of an equilateral triangle are equal, all three angles are equal, too.
Answer: Y=-1 or Y=-1+4
Step-by-step explanation:
<h3>Use the formula y2- y1 over x2-x1 so it should look like this 1-3 over 3-1 which is -2 over 2 then you divide that which is -1 and if you have to find one all you have to do is use one point label which is x and y so I pick (1,3) so you put 3=-1(1) once you have that you multipy so -1 times 1 is -1 so your gonna add 1 to the -1 and the three the -1 cancel out because it is a zero pair 3+1 is 4 so B=4 </h3>
Answer:
Option B
Step-by-step explanation:
A unit circle means radius of the circle = 1 unit
Let a terminal point on the circle is (x, y) and angle between the point P and x-axis is θ.
Center of the circle is origin (0, 0).
Therefore, ordered pair representing the terminal point will be (OP×Cosθ, OP×Sinθ) = 
OP.Cosθ = 1×Cosθ = 
Cosθ =
θ = 
, 
where n = integers
Similarly, OP×Sinθ = 1×Sinθ = -
Sinθ = -
θ = 
, where n = integer
Common value of θ will be, θ = 
Option B will be the answer.
