Answer:
10/12 or 5/6
Step-by-step explanation:
1/2 + 1/2 = 1
5/12 + 5/12 = 10/12 or 5/6
Answer:
A = 90°
B = 37°
C = 53°
Step-by-step explanation:
Given three sides of a triangle, the Law of Cosines can be used to find the angles.
__
For angle A (the largest), we can use ...
a² = b² +c² -2bc·cos(A)
Solving for A, we get ...
A = arccos((b² +c² -a²)/(2bc)) = arccos((3² +4² -5²)/(2·3·4)) = arccos(0)
A = 90°
We can use a similar equation for angle B:
B = arccos((a² +c² -b²)/(2ac)) = arccos((25 +16 -9)/(2·5.4)) = arccos(4/5)
B ≈ 37°
The sum of angles is 180°, so ...
C = 180° -90° -37°
C = 53°
Answer: B
Step-by-step explanation:
We can find the correct equation by finding the x-intercepts, or the zeroes.
To find the x-intercept, you have to make the y's value = 0. If y on the graph is zero, the x-intercept is (-1,0) and (3,0).
Then look at the equations and see which one has -1 and 3 as the values of x.
The answer is B.
Answer:
No graph attached, but it would look like;
The y intercept (the line which meets the y axis) would be at positive 2,
it would then rise one and go over 3 to the right because they are both positive.
