Answer:
14 ft/sec
so 14 feet in one second.
Hope this helps you :)
Good Luck :)))
Equation of the line is 3x + y + 4 = 0
Step-by-step explanation:
- Step 1: Given points are (1, -7) and (-4,8)
⇒ x1 = 1, x2 = -4, y1 = -7, y2 = 8
- Step 2: Form equation for the line using (y-y1) = m(x-x1). Find slope m.
⇒ m = (y2 - y1)/(x2-x1) = (8 - -7)/(-4 - 1) = 15/-5 = -3
- Step 3: Substitute the values and form the equation.
⇒ y - -7 = -3(x - 1)
⇒ y + 7 = -3x + 3
⇒ 3x + y + 4 = 0
Answer:
(3k² - 2k + 5) - (2k² - 5k + 1)
k² + 3k + 4 is the answer in simplify this expression
Answer:
Since we know that ΔPQR is a right triangle, we can also asume that:
sin R = cos P = 3/5
So the answer is (d).
* This formular can also be applied to other right triangles.
In a right triangle, sine of one acute angle will always be equal to cosine of the other acute angle.
And we can check this by actually finding cos P using the lengths of the sides, by calculating PR first:
PR = √(PQ² + RQ²) = √(12² + 16²) = 20
=> cos P = PQ/PR = 12/20 = 3/5
