Hello! answer: 252
Step-by-step explanation:
To find parelogram area you do base × height so... 21 × 12 = 252 therefore 252 is the area Hope that helps!
Answer:
x=9.768
y=6.972
Step-by-step explanation:
For this problem we have to use the trig relationships of cos and sin to figure out the lengths. Cos is equal to adjacent/hypotenuse so we can set it as x/r=.814 and since r is equal to 12 we can do 12 times .814 to get x.
We do a similar process for sin but sin is equal to opposite/hypotenuse so we can set up the equation y/r=.581 and we simply multiply both sides by 12 to get 12*.581 to get y.
Also for future reference adjacent and hypotenuse are based on the angle at use, since ∅ is on the bottom left x is the adjacent side and y is the opposite side.
Ok so the dependent variable would be $1.45 for each addition hour. The cost depends on every hour so u can't really calculate it unless u have the hours.
$3 is independent since it's only charged on the first hour. It doesn't rely on any other information.
a) 4k^2 + k – 5) + (7k^2 + 2k + 6)
11k^2 +3k +1
Choice A
