Another way to answer this question would be(X+y)^3-5
Answer:
9, 12, -5
Step-by-step explanation:
Let us move all the terms to one side.
9x^2+12x-5=0
Therefore, using the quad formula of ax^2+by+c=0,
a=9
b=12
c=-5
Hope this helps! :)
Answer:
Step-by-step explanation:
Velocity of first Person 
Velocity of second Person 
Distance between them P=100 ft
Let x be the distance moved by 1 st and y be the distance moved by second person by the time 12:02 PM
In Triangle ABC
using Pythagoras
differentiating with respect to time
AC after 2 minute
Answer:
The answer is the first one. Inside the absolute value symbols it is negative but absolute value answers are always positive. Instead of -30 the answer is 30.
7.) Area of a square pyramid is given by A = s^2 + 2sl; where s is the side length of the base and l is the slant height.
Area of given pyramid = 4^2 + (2 x 4 x 7) = 16 + 56 = 72 ft^2
8.) Area of the given pyramid is the area of the hexagonal base plus the area of the six slant triangles.
Area of hexagonal base = (3sqrt(3))/2 x 10^2 = 150 x 1.732 = 259.8
Area of the 6 traingles = 6(1/2 x 10 x 13) = 6 x 65 = 390
Total surface area of the pyramid = 259.8 + 390 = 649.8 ≈ 650 m^2
9.) Using pythagoras rule, the slant height is sqrt(6^2 + 3.5^2) = sqrt(36 + 12.25) = sqrt(48.25) = 6.9 mm
10.) The surface area of a cone is given by πr^2 + πrl
Area = π x 6^2 + π x 6 x 20 = 36π + 120π = 490.1 cm^2
11.) l = sqrt(r^2 + h^2) = sqrt(11^2 + 16^2) = sqrt(121 + 256) = sqrt(377) = 19m
