Answer 1

Answer: -3π/2

Step-by-step explanation:

The unit circle is tricky, but here are some things to know:

When measuring angles, you usually move in the counter-clockwise direction. If you are moving clockwise (like shown in your picture), the angle will be negative. The unit circle is typically measured in radians, not degrees

              - To convert from radians to degrees, multiply by 180/π

              - To convert from degrees to radians, multiply by π/180

The whole unit circle measures 2π (360 degrees). This means that the positive x-axis can be referred to as 0 or 2π, the positive y-axis is referred to as π/2, the negative x-axis is referred to as π, and the negative y-axis is referred to as 3π/2.

              -If the angle is negative, switch the signs of the axis above.

The information above is all you need to answer the above question, but if you want/need anything else on the unit circle, just let me know.

– 6 £ 2y < 5

y is an integer.



Write down all the possible values of y.

Answers

Answer:

Step-by-step explanation:

Given the inequality expression – 6 + 2y < 5

We are to find all the possible values of x

-6 + 2 y < 5

Add 6 to both sides

-6 + 2y + 6 < 5 + 6

2y < 11

Divide both sides by 2

2y/2 < 11/2

y < 11/2

y < 5.5

hence the possible values of y are all values less than 5.5

54- 7= 47

Total - 7 = her score

Kenji drives 18.4 miles in 16 minutes. He passes a sign, which gives the speed limit as 60 mph. By how much, in mph, did Kenji's average speed exceed the speed limit?

Answers

The amount of speed by which kendri exceeded the speed limit is; 9 mph

We are given;

Distance; d = 18.4 miles

Time; t = 16 minutes = (16/60) hours

Now, the formula for speed is;

Speed = distance/time

Thus, let's Calculate kenji's speed;

Kenji's speed = 18.4/(16/60)

Kenji's speed = 69 mph

We are told that the speed limit is to be 60 mph, this means that kendri exceeded the speed limit by;

69 - 60 = 9 mph

Answers

Given:

The set of ordered pairs is

{(0.5,2), (1.5,5), (4.0,12), (6.5,15)}

To find:

Which relation has the same domain as the given relation?

Solution:

We know that, domain is the set of input values or x-values.

For the given set {(0.5,2), (1.5,5), (4.0,12), (6.5,15)}, the domain is

Domain={0.5, 1.5, 4.0, 6.5}

Similarly,

For {(1,5),(2,2),(-3,15),(-8,12)},

Domain = {1, 2, -3,-8}

For {(0.5,1),(1.5,4),(4.0,11),(6.5,14)},

Domain={0.5, 1.5, 4.0, 6.5}

For {(2,1,1),(5,2.2),(12,3.3),(15,4.4)},

Domain = {2, 5, 12, 15}

For {(-1,6.5),(-3,1.5),(-6,4.0),(-10,0.5)}​,

Domain = {-1, -3, -6, -10}

So, the relation {(0.5,1),(1.5,4),(4.0,11),(6.5,14)} has the same domain as the given relation.

Therefore, the correct option is B.

3/10 + 4/100 = ???

.

Answers

Answer:

34/100

Step-by-step explanation:

Answer:

17/50

Step-by-step explanation:

Hi!

How you want to go about this is first make the 3/10 into 30/100 to make it match up with 4/100.

You want the denominators to both be 100 so they match.

So you would do this by finding 10 x what gets you to 100.

You could eyeball it and see that 10 x 10 = 100 or go backwards (right to left horizontally) and divide 100 / 10 to get 10.

But now what we have is :

30/100 + 4/100

All you have to do is add the first numbers and simplify if possible.

30 + 4 = 34

So :

34/100

To simplify we can divide both numbers by 2 :

34/2

100/2

17/50

And that is our final answer.

I hope this helped!

Answers

Answer:

A. y = -4x + 2  and  B. 2x + 2y = 6      

Step-by-step explanation:

A. y = -4x + 2        This is correct since the displayed picture shows a negative slope. Therefore, m is negative

B. 2x + 2y = 6       This is converted to     y = -x +3   So, it is also correct

C.  2x - y = 7           This is converted to y = 2x-7      So, it is not correct

D. y = 5                   Y value would have to always be at 5  So, it is not correct
