Answer:
We are given that the pyramid has a square base that is inscribed in the circular base of a cone.
" To inscribe something means to draw (a figure) within another so that their boundaries touch but do not intersect "
Hence we have to draw a figure such that the vertices of the square base of pyramid touch the points on the circle which is a base of a circular cone and also the top of the pyramid touches the top of the cone.
The figure of this question is attached to the answer.
Answer:
the area of ∆ABC = 9
Step-by-step explanation:
<em>Since</em> CA = CB <em>then</em> A(-1,2), B (5,2) and C (2,5) are the vertices of an isosceles triangle.
Area calculation:
Let The point H be the midpoint of side AB
Then
H(2 , 2)
therefore,
Finally,
Answer:
The answer is: 13 minutes
Step-by-step explanation:
First Let us form equations with the statements in the two scenario
Let the time in which the bell rings be 'x'
1. If Andrew walks (50 meters/minute), he arrives 3 minutes after the bell rings. Therefore the time of arrival at this speed = (3 + x) minutes
2. If Andrew runs (80 meters/minute), he arrives 3 minutes before the bell rings. Therefore the time taken to travel the distance = (x - 3) minutes
In both cases, the same distance is travelled, therefore, equation (1) = equation (2)
Next, collecting like terms:
dividing both sides by 3:
x = 390÷30 = 13
∴ x = 13 minutes
Answer: The period of
is
.
Step-by-step explanation:
To find the period of a trigonometric function, we use the formula
. In this case, b = 3, so we plug it in:
Therefore, the period of is
