Answer:
60
Step-by-step explanation:
b = the hypotenuse of a right angle triangle
a = the adjacent side.
R is being defined by the cosine
cos(R) = adjacent / hypotenuse
adjacent = 16* sqrt(2)
hypotenuse = 32*sqrt(2)
Cos(R) = 16*sqrt(2) / 32*sqrt(2) sqrt(2) cancels.
cos(R) = 1/2
R = cos-1(1/2)
R = 60 degrees.
Is there a worksheet that goes with it? So I can understand better
Approximately 68% of a normal distribution lies within one standard deviation of the mean, so this corresponds to students with scores between
.
The value of 'k' in the quadratic Equation having one rational solution is k is 8.
<h3>
What is a Quadratic Equation?</h3>
- Quadratic equations are the polynomial equations of degree 2 in one variable of the type where a, b, c, ∈ R and a ≠ 0.
- The standard form of a quadratic equation is .
Here, the given equation is
By comparing the given equation with the standard form of the quadratic equation we get,
a = 4
b = k
c = 4
The given quadratic is having one rational solution, which means
Therefore,
Therefore, the value of k is 8.
