Answer: 13.6 units
Step-by-step explanation:
Given the following :
Dilation rule : DQ, 0.15
The dilation factor is 0.15
Distance between Q and A' = 2.4
To calculate the distance 'x' between A and A'
The entire length of the side is calculated, that is, A to Q(center of dilation)
Length of A to Q = (Distance A' to Q) / dilation factor
Length of A to Q = 2.4 / 0.15 = 16
Distance (A to A') = x ;
Length AQ - length A'Q
16 - 2.4 = 13.6 units
Answer: 289 ft.
Explanation:
You can form a right triangle with these features:
1) Base = adjacent-leg = 500 feet
2) angle between the hypotenuse and the base = 30° ( I use 30° instead of 30', because 30' does not make sense, it is a too small angle)
3) Height = opposite-leg = height of the Statue of LIberty = x
Now, use the equation for the trigonometric ratio tangent:
tan(angle) = opposite-leg / adjacent-leg
=> tan (30°) = x / 500ft
=> x = 500ft * tan(30°)
x = 288.67 ft which rounded to the nearest foot is 289 ft.
The sum of the amounts of change in the bacteria after the seventh day is 6554.
<h3>What is the geometric sequence about?</h3>
The sequence are:
2, -8, 32, -128
Note that a first term of:
(a) of 2
A common ratio (r) of -8/2 = -4.
So the sum of n terms is said to be:
Sn = a1·(r^ n -1)/(r -1)
For the given sequence, the sum of 7 terms is said to be:
S7 = 2·((-4)^7 -1)/(-4-1)
= 2(-16384/-5)
= 6554
Therefore, The sum of the amounts of change in the bacteria after the seventh day is 6554.
