Answer:
Step-by-step explanation:
Hey sweetie!
We are given two points: (-7, 9) & (5, 5)
And we are asked to find the slope
To do this only given two points use the Slope-Formula to solve for the slope
m = slope
m = y2-y1/x2-x1
m = 5-9/5–7
m = -4/12
m = - 1/3
The slope will be - 1/3
Final Answer: m = - 1/3
Answer:
- sin = √(1 -cos²)
- tan = (√(1 -cos²))/cos
Step-by-step explanation:
_____
If you draw a triangle with a hypotenuse of 1 and an "adjacent" leg of "cos", then using the Pythagorean theorem, you can see that the "opposite" leg will be √(1-cos²) and the tangent will be (√(1-cos²))/cos. Whether or not you're allowed to draw such a triangle on paper, you can certainly do it in your mind.
Answer:
The answer Is C...........I'm pretty sure correct me if I'm wrong srry:/
Density = kg/m3 or g/cm3
hence,
4500 ÷ 0.5 = answer.
Answer:
d = (a[n2] -a[n1])/(n2 -n1)
a1 = a[n1] -d(n1 -1)
Step-by-step explanation:
The generic term is ...
an = a1 +d(n -1)
Fill in the values associated with the two terms and solve the simultaneous equations.
For terms n1 and n2, their difference will be ...
a[n2] -a[n1] = (a1 +d(n2 -1)) -(a1 +d(n1 -1)) = d(n2 -n1)
Dividing by the coefficient of d tells you ...
d = (a[n2] -a[n1])/(n2 -n1)
Once you have the value of d, you can find the first term.
a[n1] = a1 +d(n1 -1)
a1 = a[n1] -d(n1 -1)
_____
<u>Example</u>:
3rd term = 12
7th term = 20
d = (20 -12)/(7 -3) = 8/4 = 2
a1 = a3 -d(3 -1) = 12 -2(2) = 8
The n-th term is ...
an = a1 +d(n -1)
an = 8 +2(n -1)
