You should substitute the values of x and y from the suggested points into the given equation and if both sides are equal then the point is on that line.
Using this, the points are (-5,5), (1,2), and (5,0)
Answer:D
Step-by-step explanation:
(3x+6)(3x+6) =9x^2+18x+18x+36=9x^2+36x+36
Answer:
Step-by-step explanation:
Present value formula;
(PV) = ![\frac{FV}{(1+r)^{n} }](https://tex.z-dn.net/?f=%5Cfrac%7BFV%7D%7B%281%2Br%29%5E%7Bn%7D%20%7D)
FV= Future amount (A) = $30,000
r = interest rate; monthly rate in this case = 7% / 12 = 0.5833% or 0.005833 as a decimal
n= total duration of investment (in months) in this case= 7*12 = 84 months
Next, plug in the numbers into the formula;
PV = ![\frac{30,000}{(1.005833)^{84} } \\ \\ =\frac{30,000}{1.62994868}](https://tex.z-dn.net/?f=%5Cfrac%7B30%2C000%7D%7B%281.005833%29%5E%7B84%7D%20%7D%20%5C%5C%20%5C%5C%20%3D%5Cfrac%7B30%2C000%7D%7B1.62994868%7D)
=18,405.48747
Therefore present value rounded to 2 decimal places = $18,405.49
Answer:
Q1: 48ft
Q2: 14.6
Step-by-step explanation:
Question 1:
Since the two triangles are similar (Angle - Side - Angle):
30/x = 50/80
x= 30(80/50)
=48
Question 2:
sin(55deg) = 12/x
12/sin(55) = x
x=14.6 (3 s.f.)
