Hello from MrBillDoesMath!
Answer:
csc (90° – x) = sec (x
)
sin (90° – x) = cos (x
)
tan (90° – x) = cot (x)
cos (90° – x) = sin (x
)
cot (90° – x) = tan (x
)
sec (90° – x) = csc (x)
Thank you,
MrB
Answer:
3.5 =k
Step-by-step explanation:
If the table is proportional, the equation is
y = kx
To find k
y/x =k
14/4 = k
7/2=k
3.5 =k
Answer:
in number 1 I think D is wrong and in number 2 A is correct
To find the circumference of a circle, use the formula:
C=2*pi*r or C=pi*d
r=radius and d=daimeter
Judging by the question you should indeed use the equation 0.2 x n = 15.
To solve this you must divide both sides by 0.2, which would result in n=75.
So, if the question is 'True or False: Use the equation 0.2xn=15 to find the value of n' then the answer is True.
