Answer:
Option A is the correct answer.
Explanation:
The given pyramid has 3 lateral triangular side as shown below.
Base of triangle = 12 unit
We need to find perpendicular.
By Pythagoras theorem we have
Perpendicular² = 10²-6²
Perpendicular = 8 unit
So area of 1 lateral triangle = 1/2 x Base x Perpendicular.
= 1/2 x 12 x 8 = 48 unit²
Area of lateral side = 3 x 48 = 144 unit²
Option A is the correct answer.
Answer:
The answer to your question is below
Step-by-step explanation:
See the graph below.
I recommend you to evaluate the function when x = (-1, 0, 1, 2, 3, and 4) to get the values of y.
Then, in the graph we look for the points where the line crosses the x-axis, these points will be the roots.
In the graph we observe that the root are x = 1 and x = 2.4
The correct answer is D) $48,000.
15% = 15/100 = 0.15
0.15(320000) = 48000
What is the explicit formula for the sequence?
3, 1, –1, –3, –5, . . .
Step-by-step explanation:
at s = -3
at s = -2
at s = -1
at s = 0
at s = 1
at s = 2
at s = 3
