Answer:

Yes, an arrow can be drawn from 10.3 so the relation is a function.

Step-by-step explanation:

Assuming the diagram on the left is the domain(the inputs) and the diagram on the right is the range(the outputs), yes, an arrow can be drawn from 10.3 and the relation will be a function.

The only time something isn't a function is if two different outputs had the same input. However, it's okay for two different inputs to have the same output.

In this problem, 10.3 is an input. If you drew an arrow from 10.3 to one of the values on the right, 10.3 would end up sharing an output with another input. This is allowed, and the relation would be classified as a function.

However, if you drew multiple arrows from 10.3 to different values on the right, then the relation would no longer be a function because 10.3, a single input, would have multiple outputs.

A parking lot charges $3 to park a car for the first hour and $2 per hour after that. If you use more than one parking space, th

Vikki [24]

Given, a parking lot charges $3 for first hour and $2 per hour after that.

So for t hours, the parking lot charges $3 for the first hour and after first hour there is $(t-1)$ hours left.

So for $(t-1)$ hours it will charge $2 per hour.

The charges for $(t-1)$ hours = $ $2(t-1)$ .

Total charges for t hours for one car = $ $(3+2(t-1))$

Now for the second car, it will charge 75% of the first car.

So the charges for second car

=$[ $(3+2(t-1))(75/100)$ ]

=$ $0.75(3+2(t-1))$

There are 3 cars. That parking charges for the third car is also 75% of the first car.

So for third car the parking charges are same as for the second car.

Total parking charges for 3 cars

= $ $(3+2(t-1))+(0.75(3+2(t-1))+(0.75(3+2(t-1))$

= $ $(3+2(t-1))+(0.75)(2(3+2(t-1))$

We have got the required answer here.

The correct option is option C.

A spool of rope contains 65 yards of rope. How many 4-foot pieces of rope can be cut from the spool? How much rope is left ov

Thepotemich [5.8K]

So there is 65 yards and one yard is 3 feet so you multiple 65 by 3 which is 195 . Then you divide by 4 as you have to see how many four foot pieces can be cut which you end up with 48.75 which means that you can have 48 four foot pieces. So since you have 48 four foot pieces you multiply 48 by 4 and you have 192 and if you subtract 195 which is how many feet there is in the 65 yards you get three feet and that is how much of the rope that is left over.

How do i do question 3 a b c

viva [34]

Answer:

a) 240°

b) 30°

c) 225°

Step-by-step explanation:

To solve these equations you have to use the inverse of the given trigonometric functions. The inverse of sin is arcsin, and the inverse of tan is arctan. Instead of giving an angle, what is its sine?, the question is: given a sine, what is the angle?.

sin(θ) = -√3/2

θ = arcsin(-√3/2)

θ = -60°

Given the periodicity of sine function, sin(-60°) is equivalent to sin(240°) (-60+180) and sin(300°) (-60+360).

tan(θ) = 1/√3

θ = arctan(1/√3)

θ = 30°

csc means cosecant, by definition:

csc(θ) = 1/sin(θ)

csc(θ) = -√2

1/sin(θ) = -√2

sin(θ) = -1/√2

θ = arcsin(-1/√2)

θ = -45° or 360-45 = 315° or 180+45 = 225°
