Answer:
5 rulers/ group
Step-by-step explanation:
Solve for either x or y
since they give you a y equation, you should find the x equation.
x - 1/3y = -3
move the -1/3y to the right and it'll be a positive
×= 1/3y-3
now plug in the x to the y equation or vise versa
I'm going to plug in the x into the y to make things faster and less complicated.
y= (x3-9)
y= (1/3^3 -9)
y= 1/27 -9
y= 9.03703
now plug in the y to the x equation.
x= 1/3y-3
x=1/3 (9.037) - 3
x= .01234
I'll round it to the hundredths place
(0.012, 9.04)
Answer:
<h3>60°</h3>
Step-by-step explanation:
Given that:
- Circumference (C) = 6 units
- Arc length (A) = 1 unit
<u>Find the central angle (</u><u>θ</u><u>)</u>
Arc is some part of circumference; thus,
the equation of arc length =
A = θ/360 × C
θ/360 = A/C
θ = (360×A)/C
θ = (360×1)/6
θ = 360 ÷ 6
<h3>θ = 60° ✅</h3>
Central angle = 60°

Answer:
Step-by-step explanation:
We are given the equation:
First, we can divide everything by 2:
Notice that we have an equation in quadratic form. Namely, if we make a substitution where u = sin(x), we acquire:
Solve for u. Factor:
Zero Product Property:
Solving for both cases:
And by substitution:
For the first case, recall that sin(x) is -1/2 for every 7π/6 and every 11π/6. Hence, for the first case, our solutions are:
Where n is an integer.
For the second case, sin(x) is -1 for every 3π/2. Thus:
All together, our solutions are:
