Answer:
formula: (y_2-y_1)/(x_2-x_1)
slope: 0
Step-by-step explanation:
1. The formula to find the slope given two points is 
.
2. (Solving)
Therefore, the slope is 0.
Answer:
√29
Step-by-step explanation:
We are here given that ,
Now square the first equation ,
⇒ a - b = 3
⇒ ( a - b)² = 3²
⇒ a² + b² - 2ab = 9
⇒ a² + b² - 2(5) = 9
⇒ a² + b² -10 = 9
⇒ a² + b² = 9 + 10
⇒ a² + b² = 19
⇒ a² + b² + 2ab = 19 + 2(5)
⇒ (a + b)² = 19 + 10
⇒ ( a + b)² = 29
⇒ a + b = √29 .
Answer:
Step-by-step explanation:
The value 0.055 is equal to 55.0 moved 3 decimal places to the left. For each decimal placed moved, divided by 10. Therefore, 0.005 as a common fraction is:
Answer:
1.
Step-by-step explanation:
1. sin 241 = sin(61 + π) = -sin61 = -t^(1/2)
2. sin^2 + cos^2 =1, cos 61= (1-t)^(1/2)
3. [2sin^2 (x)sin(x) +2cos^2 (x)sin(x)]/2cos(x) = 2sin(x) / 2cos(x) = tan(x)
4. tan (x), x do not equal to （π/2 +or- kπ）
x do not equal to 90，270。
Answer:
it would be rounded to 9 as the nearest whole number (the number in decimal form is 9.304 when added up to get the sum)
