Hi there!
In order to solve, we'll need to use the slope formula. The slope formula is y2 - y1 / x2 - x1. The y values are on top because the slope is the rise of the line over the run of the line.
WORK:
Formula - y2 - y1 / x2 - x1
Plugging in values - 8 - 2 / 9 - 6
Subtracting - 6 / 3
Divide - The slope is 2
ANSWER:
Option 3 - 2
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
8+ the product of 2 and a number to the third power, what it means 2×m cubed. So it is 8+2m (cubed)
Answer:
6(2x-5) when factored
Step-by-step explanation:
They are both fractions, but 3/3 is 1 whole and 4/4 is 1 whole also.
so 1 whole times 1 whole equals 1
number form of my explanation:
3/3=1
4/4=1
1x1=1
Describe complete!
Answer:
1.8 units.
Step-by-step explanation:
The questions which involve calculating the angles and the sides of a triangle either require the sine rule or the cosine rule. In this question, the two sides that are given are adjacent to each other and the given angle is the included angle. This means that the angle is formed by the intersection of the two lines. Therefore, cosine rule will be used to calculate the length of the largest side of the triangle. The cosine rule is:
b^2 = a^2 + c^2 - 2*a*c*cos(B).
The question specifies that a=0.5, B=120°, and c=1.5. Plugging in the values:
b^2 = 0.5^2 + 1.5^2 - 2(0.5)(1.5)*cos(120°).
Simplifying gives:
b^2 = 3.25.
Taking square root on the both sides gives b = 1.8 (rounded to the nearest tenth).
This means that the length of the third side is 1.8 units!!!
