Answer:
Lateral area of the cone = 4,712 m (Approx)
Step-by-step explanation:
Given:
Height of cone (h) = 40m
Radius (r) = Diameter / 2 = 60 / 2 = 30m
Find:
Lateral area of the cone = ? ?
Computation:
Answer:
(-1, -1)
Step-by-step explanation:
I can't graph it, but I can give you 2 points. Graph the line passing through (-1, -1) and (0, 3) and another passing through (-1, -1) and (0, -5).
Answer:
D’=(3,3); F’=(-2,-2); E’= (-5,0)
Step-by-step explanation:
To find the reflection over the y axis (the line x=0), you just need to change the x either from positive to negactive or the opposite.
Note that this is a quadratic function whose graph opens down. You could plot this function and note the coordinates of the vertex; the y-coordinate would be the max value of the function.
Alternatively, find x = -b/(2a), where a = -2, b = 8 and c = -5. Then find the corresponding y-value.
Alternatively, find the derivative of f(x) and set it = to 0. Solve for x. Find the y value associated with this x. That y-value is the max of f(x).
Option(d)is the answer...
We know that area of the triangle is 1/2bh
=>1/2*7.2*4.8
=>3.6*4.8
=>17.28in sq....
=>17.3in sq(approx)....
Hope this helps u.....
