Answer:
a) -tan(π/4) = -1
b) -1/sin(π/3) = -(2/3)√3
Step-by-step explanation:
The given functions are reciprocals of the primary trig functions:
cot(x) = 1/tan(x)
csc(x) = 1/sin(x)
The tangent function has a period of π, and is equal to the cotangent of the complementary angle.

<h3>a)</h3>
The given angle is an alias of -π/4, so we can write ...
cot(7π/4) = cot(-π/4) = -cot(π/4) = -tan(π/2 -π/4) = -tan(π/4)
-tan(π/4) = -1
__
<h3>b)</h3>
csc(-π/3) = 1/sin(-π/3) = -1/sin(π/3) = -1/(√3/2) = -2/√3
-1/sin(π/3) = -2√3/3
Fraction: 1/20
Decimal: 0.05
i guess i got the answer ...
well..... four times a number b = 4×b = 4b
one more than is +1
and this = 17
now we need to put it all together and forma an equation .... so .. it will be
4b + 1 = 17
4b = 17 - 1
4b = 16
b = 16/4
∴ b = 4
Those are known as dividends
Answer:
approximately 54.7% did not respond.
Step-by-step explanation:
Consider the provided information.
The college chooses 150 businesses at random from telephone listings.
Of these, 68 return the questionnaire.
That means 68 of them responded.
The number of people who did not respond are:
150-68=82
The number of people who did not respond are 82.
Now find the percentage of people who did not respond.
Hence, approximately 54.7% did not respond.
