Any function that has a -b value divided by 2a that equals -2
use ax²+bx+c to figure it out
the axis of symmetry formula is -b/2a=x
We see that city A gets 105 cm of snow while city B gets 2.8 m. The first thing we do is make both measurements equal to each other. This can be done by either converting city A's 105 centimeters to meters or city B's meters to centimeters. But the question specifically calls for both, so we get both measurements.
City A: 105 centimeters OR 1.05 meters
City B: 280 centimeters OR 2.8 meters
Now that we know the measurements, let's look at the first problem. (A) asks for the difference in one year in meters. The difference of course means subtraction. Now it's here where I personally am confused on what it asking for in terms of which city is it asking for us to subtract from, but using an educated guess, I'll say we're subtracting from city B because if we were to subtract from city A, we'd have a negative, and you can't have a negative amount of snow, only 0 snow.
So once again, for question (A), we subtract 1.05 from 2.8 (2.80 - 1.05) and we get 1.75 meters of snow.
Question (B) asks for the difference during two years in centimeters, so we multiply both measurements by 2 and use the centimeter measurements. (105 x 2 = 210) (280 x 2 = 560) Subtract 560 from 210 (560 - 210) and we get 350 centimeters.
So your answers are: (A) 1.75 meters (B) 350 centimeters
I hope this helps!
Answer: k ≥ -1
Step-by-step explanation:
7k - 2 ≥ -9
add two to both sides
7k ≥ -7
k ≥ -1
If you are ordering packaging for a product you would be more concerned with volume as the volume would tell you how much space something takes up so how much packaging you need to order for it.
Answer:
x = 24°
Step-by-step explanation:
To find 'x', the Alternate Exterior angle postulate will need to be used.
'4x + 9' and '2x + 27' are alternate exterior angles. Therefore, they must sum up to 180.
180 = 4x + 9 + 2x + 27
Combine like terms:
180 = 6x + 36
144 = 6x
x = 24°
