Answer:
6 - 
3² - 
7 - 
= 
Step-by-step explanation:
1. 6 - 
First, apply the exponent to 2/3. Because it's to the second power, multiply 2/3 by itself.
6 - 
Now, subtract.
6 - =
------------------------------------------
2. 3² - 
First, apply the exponent.
3² = 9
9 -
Now, subtract.
9 - 
------------------------------------------
3. 7 -
First, apply the exponent.
= 
7 -
Now, subtract.
7 - 
hope this helps!
Step-by-step explanation:
It is given that, Katie walks 2 ft forward and 5 ft backwards. We need to find her displacement traveled.
The difference between final position and the initial position is equal to displacement. It is the shorted path covered.
Let forward is +x and backward is -x
Initial position of Katie = +2 ft
Final position of Katie = -5 ft
Displacement = final position - initial position
= -5 - 2
Displacement = -7 ft
So, her displacement is 7 feet in backward direction.
Answer:
One of the errors that I saw was that she multiplied by -5 instead of dividing
Step-by-step explanation
R = 2 / (1 + sin <span>θ)
Using the following relations:
R = sqrt (x^2 + y^2)
sin </span>θ = y/R
<span>
R = 2 / (1 + y/R)
R</span>(1 + y/R<span>) = 2
</span><span>R + y = 2
R = 2 - y
sqrt(x^2 + y^2) = 2 - y
Squaring both sides:
x^2 + y^2 = (2 - y)^2
x^2 + y^2 = 4 - 4y + y^2
x^2 + 4y - 4
</span>
