When graphing slope, it is important to remember y= mx+b (slope formula). m is the slope, b is the y- intercept, and x, y are the coordinates. Starting at the y- intercept, graph the slope (rise over run). For the first question, the slope is 1/2. From the y- intercept, move up the y- axis one, and move across the x- axis two. The numerator represents the rise, while the denominator represents the run.
Your constant is 3 because it’s alone
The answer is c Bc it’s bigger than what it’s talking about
Answer:
0.43%
Step-by-step explanation: Since there are 13 girls, you need to do 13/30 to find the percentage of girls.
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.
