Answer:
Step-by-step explanation:
Which is true about the solution to the system of inequalities shown?
y 3x + 1
y 3x - 3
Only values that satisfy y 3x + 1 are solutions
Only values that satisfy y 3x3 are solutions
Values that satisfy either y a 3x + 1 orys 3x - 3 are solutions
So firstly, you're gonna replace the T variable with 2.2, which is the time given to us. And so the equation is gonna look like this:
and we will be solving for L.
The next thing you wanna do multiply 2 and 3.14 together, so your equation should look like this:
After that, you're gonna want to square all the terms in this equation (2.2, 6.28, and
) to remove the square root. Your equation will look like this
Next up is you're gonna multiply 32, the reciprocal of 1/32, on each side so that the equation looks like this
After, you're gonna divide 39.4384 on each side, and your equation should end up at
. And assuming from your options, they are gonna want you to round to the nearest whole number, so the best option is 4 feet.
Observe that
|√3 + i| = √((√3)² + 1²) = √4 = 2
and
arg(√3 + i) = arctan(1/√3) = π/6
so that
√3 + i = 2 exp(i π/6)
By de Moivre's theorem, we get
(√3 + i)⁶⁰ = 2⁶⁰ exp(i π/6 • 60) = 2⁶⁰ exp(i 10π) = 2⁶⁰
Commutative property is "a + b = b + a"
Therefore your answer is 1. 5 + 6 = 6 + 5
