Answer:
a² - b² = 1
Step-by-step explanation:
The given parameters are;
sec 50° = a
cot 40° = b
We note that sec(θ) = 1/cos(θ) and cot(θ) = 1/tan(θ)
a² - b² = sec²50° - cot²40°
Given that sec(90 - θ) = cosec(θ) where; cosec(θ) = 1/sin(θ), we have;
sec²50° - cot²40° = sec²(90° - 50°) - cot²40° = sec²(40°) - cot²40°
sec²(40°) - cot²40° = cosec²(40°) - cot²40°
Also we have;
cosoc²(θ) = 1 + cot²(θ)
Therefore, we have;
cosoc²(40°) - cot²40° = 1 + cot²(40°) - cot²40° = 1
Therefore, where sec(50°) = a and cot(40°) = b, the value of a² - b² is 1.
Answer:
5. The initial value corresponds to the y value when x = 0.
Step-by-step explanation:
You are given the graph, so you do not need to plot anything. Finding rise over run does nothing to help you find the initial value.
The "initial value" on a graph of a linear function is also known as the "y-intercept." It is the y-value corresponding to x = 0.
Answer:
0.04/n
Step-by-step explanation:
whichever number is being divided goes in the numerator, so 0.04 is the numerator and n is the denominator
(2*3+x^2)+3(234x^2)
=6+x^2+702x^2
=703x^2+6
Do you have a specific equation I can help you with. I can explain them better with a problem to look at?
