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
Answer:

Step-by-step explanation:
Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)
Answer:
2x10^3
Step-by-step explanation:
(5x10^-3) is .005
(4x10^5) is 400,000
Multiply together and you get 2000
move the decimal to the right 3 times and you get 2x10^3
The formula for area of a trapezoid is 1/2 h (base1+base2) so, if you input the information, it becomes 1/2 14(19+23) simplified once: 7(42) final answer: 294cm².
