Step-by-step explanation:
Look at the picture.
Coordinates of a point (x, y)
x - from x-axis
y - from y-axis
Answer:
pick a group of 3 randomly: 10C3 = 120
pick a group of 3 girls: 4C3 = 4
Probability=4/120=1/30
Answer:
a =
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.:
<em>Suppose ABC is a right triangle with sides a, b, and c and right angle at C. Find the unknown side length using the Pythagorean theorem and then find the values of the six trigonometric functions for angle B. when b=3 and c=4</em>.
My answer:
We will Pythagoras theorem, which states that the sum of squares of two legs of a right triangle is equal to the square of the hypotenuse of right triangle. Because the question says that ABC is a right triangle.
Given that: b=3 and c=4
so a =
We know that tangent relates opposite side of a right triangle with adjacent side.
Please have a look at the attached photos.
Answer:
b = 1
Step-by-step explanation:
they are asking what is y when x is -4. We can look on the graph and see that when x = -4, when is 1. It is the point (-4,1).
We can also see it algebraically. We can replace x with -4 and solve for y
y = 1/4 x + 2
y = 1/4((-4) + 2
y = -1 + 2
y = 1
