Answer:
11, -4
Step-by-step explanation:
![x = \frac{ - b + \sqrt{ {(b)}^{2} + - 4(a)(c) } }{2a}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B%20-%20b%20%2B%20%20%5Csqrt%7B%20%7B%28b%29%7D%5E%7B2%7D%20%2B%20-%204%28a%29%28c%29%20%7D%20%7D%7B2a%7D%20)
![x = \frac{ - b - \sqrt{ {(b)}^{2} + - 4(a)(c) } }{2a}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B%20-%20b%20%20-%20%20%20%5Csqrt%7B%20%7B%28b%29%7D%5E%7B2%7D%20%2B%20-%204%28a%29%28c%29%20%7D%20%7D%7B2a%7D%20)
you have to do both of these top equations
a = 1
b = -7
c = -34 - 10 = -44
substitute these numbers into both equations to get x
x = 11 , -4
Answer:
y-1=5(x-3)
Step-by-step explanation:
y-y1=m(x-x1)
m=5
y-1=5(x-3)
Curl is defined as:
![\bigtriangledown \times F=\frac{ \int F.dr}{Area}](https://tex.z-dn.net/?f=%5Cbigtriangledown%20%5Ctimes%20F%3D%5Cfrac%7B%20%5Cint%20F.dr%7D%7BArea%7D)
Which can be rewritten as:
![\frac{ \int F.dr}{Area}=\frac{ \int_{C_1} Fdr}{Area}\widehat{k}+\frac{ \int_{C_2} Fdr}{Area}\widehat{i}+\frac{ \int_{C_3} Fdr}{Area}\widehat{j}](https://tex.z-dn.net/?f=%5Cfrac%7B%20%5Cint%20F.dr%7D%7BArea%7D%3D%5Cfrac%7B%20%5Cint_%7BC_1%7D%20Fdr%7D%7BArea%7D%5Cwidehat%7Bk%7D%2B%5Cfrac%7B%20%5Cint_%7BC_2%7D%20Fdr%7D%7BArea%7D%5Cwidehat%7Bi%7D%2B%5Cfrac%7B%20%5Cint_%7BC_3%7D%20Fdr%7D%7BArea%7D%5Cwidehat%7Bj%7D)
This is because C1 lies on the xy plane and thus it's unit vector will be
.
By similar arguments the rest will follow too.
Now, area of each circle will be: ![\pi \times (0.1)^2=0.01 \pi](https://tex.z-dn.net/?f=%5Cpi%20%5Ctimes%20%280.1%29%5E2%3D0.01%20%5Cpi)
Therefore, Curl, as per our definition will be:
![\frac{\int F.dr}{Area}=\frac{0.01\pi}{0.01\pi}\widehat{k}+\frac{0.4\pi}{0.01\pi}\widehat{i}+\frac{5 \pi}{0.01\pi}\widehat{j}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cint%20F.dr%7D%7BArea%7D%3D%5Cfrac%7B0.01%5Cpi%7D%7B0.01%5Cpi%7D%5Cwidehat%7Bk%7D%2B%5Cfrac%7B0.4%5Cpi%7D%7B0.01%5Cpi%7D%5Cwidehat%7Bi%7D%2B%5Cfrac%7B5%20%5Cpi%7D%7B0.01%5Cpi%7D%5Cwidehat%7Bj%7D)
Thus, Curl=![40\pi \widehat{i}+500\pi \widehat{j} +\widehat{k}](https://tex.z-dn.net/?f=40%5Cpi%20%5Cwidehat%7Bi%7D%2B500%5Cpi%20%5Cwidehat%7Bj%7D%20%2B%5Cwidehat%7Bk%7D)
Which is the required answer.
Hi!
Change 719.711 to 720 and 8.75 is 9.
and 720 dividided by 9 is 80
Change 719.711 to 700 and 8.75 to 9.
700 divided by 9 is 77.77...
those are the only two I can think of that'll work, but I think that 80 would be the best answer.
Answer:
Jay did.
Step-by-step explanation:
Jay ate 2/3 of a pizza, while Darrell ate 2/4
2/3 is greater, like 6/9, but, 2/4 is only half, like 4.5/9
