Answer:
5.2 x 10^-2
Step-by-step explanation:
Scientific notation is used to simplify very large or very small numbers.
The formula for scientific notation is (a x 10^ n)
(a) is a number that is both greater than 1 and less than 10
(n) is the number of places the decimal place moves. This number can be positive or negative depending on the number you are converting. If the original number is greater than 1 (n) will be positive, and if the number is less than 1 (n) will be negative.
First you should write out the number.
0.052
Then, you should determine the number places the decimal point must move, and create a number greater than 1 and less than 10. (You should also pay attention to the direction the decimal point moves)
For this problem you will move the decimal place 2 places to the right to create the number 5.2.
Last, substitute the values into the formula. For this problem (a)= 5.2 and (n)= -2. This gives us the expression 5.2 x 10^-2.
The height of radio tower is 576 feet approximately
<em><u>Solution:</u></em>
Given that, radio tower casts a shadow 8 feet long
At the same time that a vertical yardstick casts a shadow half an inch long
To find: height of radio tower
Let "x" be the height of radio tower
length of shadow of tower = 8 feet
Length of shadow of stick =
Convert inch to feet
Thus,
Length of shadow of stick = 0.0416 feet
Length of vertical yard stick = 3 feet (since 1 yard = 3 feet )
Therefore, by proportion we get,
Substituting the values we get,
Thus height of radio tower is 576 feet approximately
x has to be greater or equal to 16,000
x ≥ 16,000
The coordinates of the original quadrilateral are (1, 2), (4, 2), (1, 4), and (4, 4). After transformation, the new coordinates are (1, −2), (4, −2), (1, −4), and (4, −4). Thus, as we can see, the y coordinates of the original points have been multiplied by -1. This happens only when there is a reflection about the x axis.
Thus, the type of transformation in question here is reflection about the x axis.
