Ten to the power is 600 because to the power means 10*10*10*10*10*10=600
Answer:
5
Step-by-step explanation:
The midpoint of segment AB is (1, 1).
Substituting these coordinates into the equation of the line,
![2(1)+3(1)-k=0 \\ \\ 5-k=0 \\ \\ k=5](https://tex.z-dn.net/?f=2%281%29%2B3%281%29-k%3D0%20%5C%5C%20%5C%5C%205-k%3D0%20%5C%5C%20%5C%5C%20k%3D5)
Answer:
![\large{x=7.4438\ cm\approx7.4\ cm}](https://tex.z-dn.net/?f=%5Clarge%7Bx%3D7.4438%5C%20cm%5Capprox7.4%5C%20cm%7D)
Step-by-step explanation:
Use tangent:
![tangent=\dfrac{opposite}{adjacent}](https://tex.z-dn.net/?f=tangent%3D%5Cdfrac%7Bopposite%7D%7Badjacent%7D)
We have:
![\alpha=28^o,\ opposite=x,\ adjacent=14\ cm](https://tex.z-dn.net/?f=%5Calpha%3D28%5Eo%2C%5C%20opposite%3Dx%2C%5C%20adjacent%3D14%5C%20cm)
![\tan28^o\approx0.5317](https://tex.z-dn.net/?f=%5Ctan28%5Eo%5Capprox0.5317)
Substitute:
<em>multiply both sides by 14</em>
![x=7.4438\ cm](https://tex.z-dn.net/?f=x%3D7.4438%5C%20cm)
54 * 100 / 78 = 69.23% of costumers order the new pizza.
52 costumers * 69.23% = 35.9996 costumers.
Now just round up and about 36 costumers will order breakfast pizza.
Hope this helps :)
Answer:
(a+6)²
by identity (a+b)²=a²+2ab+b²
(a+6)²= a²+ 2×a×6 + 6²
= a²+ 12a + 36
(2a)²+5a = 4a²+5a
