Answer:
There are 400 possible zip codes in the Houston area
Step-by-step explanation:
Here, we want to calculate the possible number of zip codes in the Houston area
We have 5 digits to form
77 is the first two digits ( this is fixed)
For the third digit, we are selecting 1 number out of 0,3,4 or 5
This means 4 C 1
The remaining digits can be any digits
We have 0-9, a total of 10 digits
The first will be 10 C 1 and the second last digit too is 10 C 1
So the number of possible zip codes will be;
4 C 1 * 10 C 1 * 10 C 1
= 4 * 10 * 10 = 400 possible zip codes
Answer:
y = -cos(x) -2
Step-by-step explanation:
Multiplying the function value by -1 reflects it across the x-axis. Adding -2 to the function value shifts it down by two units.
reflected: y = -cos(x)
then shifted: y = -cos(x) -2

Answer:
Below
Step-by-step explanation:
You can use Pythagorean theorem to find the hypotenuse of a right triangle.
a2 + b2 = c2
The square root of 15 = 3.8729.... (a bunch of other numbers)
4^2 + 3.8729^2 = c2
16 + 15 = 31
Now that you have this, you need to find the square root
The square root of 31 = 5.56775436
Rounding this to the tenth it would be: 5.57
Final answer: C = 5.57
hope this helps! :)
Answer: A. 5,000 meters
Step-by-step explanation:
Starting with the smallest unit which is option C. There are 10 millimeters in one centimetre. Option c in centimeters is:
= 30,000 / 10
= 3,000 meters.
Option c is smaller than B and so is incorrect.
A meter is 100 centimeters. Option b in meters is;
= 6,000 / 100
= 60 meters
This is less than option A so is incorrect.
A kilometer is 1,000 meters so option A in meters is:
= 5,000 / 1,000
= 5 kilometers
This is higher than option d so option A is correct.
