Answer:

#1: -2 ≤ y ≤ ∞

#2: -2 ≤ x ≤ 2

#3: -4 ≤ y ≤ 3

#4: -5 ≤ y ≤ ∞

#5: 0 ≤ x ≤ ∞

Step-by-step explanation:

To do these, you must understand what range and domain are:

Range: all the values that y can be

Domain: all the values that x can be

#1: It's asking for range, so look at the posible y values. The smallest y value is -2, and the largest is actually infinity. So, the range is: -2 ≤ y ≤ ∞.

#2: It's asking for domain, so look at the possible x values. The smallest is -2 and the largest is 2, so: -2 ≤ x ≤ 2.

#3: Again, it's asking for range, so look at the possible y values. The smallest is -4, and the largest is 3, so: -4 ≤ y ≤ 3.

#4: It's asking for range. The smallest value is -5, and the largest goes to infinity (from the arrows), so: -5 ≤ y ≤ ∞.

#5: It's asking for domain. The smallest x value is 0, and it goes to infinity. So: 0 ≤ x ≤ ∞.

Oranges cost $3.42 for 9 pounds at that rate how much would 12 pounds cost
o-na [289]

ANSWER

$12.56

EXPLANATION

Orange costs $3.42 for 9 pounds.

We want to know how much it would cost to get 12 pounds of oranges.

To do this, we will simply compare and make our unkown x:

$3.42 = 9 pounds

x = 12 pounds

Now, we cross multiply:

=> x * 9 = 3.42 * 12

\begin{gathered} x\text{ = }\frac{3.42\cdot\text{ 12}}{9} \\ x\text{ = \$4.56} \end{gathered}

At this rate, 12 pounds will cost $4.56.

Find all solutions to 2sin(θ)=√3 on the interval 0≤θ<2π
makkiz [27]

Answer:

2sin(3θ) - √3 = 0

Step-by-step explanation:

 sin(3θ) = √3/2

 

3θ = π/3 + 2kπ or 2π/3 + 2kπ, k = 0, ±1, ±2, ±3,...

 

θ = π/9 + 2kπ/3, 2π/9 + 2kπ/3

 

If k = 0, we get θ = π/9, 2π/9

If k = 1, we get θ = 7π/9, 8π/9

If k = 2, we get θ = 13π/9, 14π/9

 

Other values of k give values of θ lying outside of the interval [0, 2π).
