Answer:

Step-by-step explanation:

Find all solutions to the equation.

7 sin^2(x) - 14 sin x + 2 = -5

7sin^2(x)-14 sin x+7 =0

sin^2(x)-2sin x+1 =0

(sinx-1)(sinx-1)=0

sinx=1

x=π/2+2pi*k, k=integer

Is 1/2 greater than 4/5

Law Incorporation [45]

For this question you should know:
1/2 = 5/10
and
4/5 = 8/10
so you can see 8/10 is greater than 5/10 so the answer is no
4/5 is greater than 1/2 :)))
i hope this is helpful

Jim drove 204 miles in 4 hours. If he can keep the same pace how long will it take him to drive 918 miles

SSSSS [86.1K]

18 hours.

Proportions and stuff.

$\frac{204}{4}$ = $\frac{918}{x}$

Cross multiply,

204x = 918 * 4

204x = 3672
/204 /204
x = 18

18 hours.
