Answer:

point A

Step-by-step explanation:

The first number of the pairs always goes on the x axis and the second pair goes on the y axis. The x axis is the horizontal line and the y axis is the vertical line. -3 would go on the negative x-axis and 3 would go on the positive y axis.

A train leaves at 1314 and arrives at 1508. It travelled at an average speed of 105 km/h.

Paraphin [41]

Answer: The train traveled 199.5 km

Step-by-step explanation:

We know the relationship:

Distance = Time*Speed

We know that the speed of the train was 105km/h

And we know that it leaves at 13:14, and arrives at 15:08.

Then the total amount of time that the train was traveling is:

T = (15 hours and 8 mins) - (13 hours and 14 mins)

= (15 - 13) hours and (8 - 14) mins

= 2 hours and (-6) mins.

We know that one hour has 60 minutes, then this is equal to:

T = 1 hour and 54 minutes.

But because the speed is kilometers per hour, we need to rewrite the 54 minutes in hours.

This can be done as follows:

1 hour = 60 minutes.

Then: 54 minutes = (54/60) hours = 0.9 hours.

Then:

1 hour and 54 minutes = 1.9 hours.

Now we know the speed and the time, then the distance can be calculated as:

Distance = speed*time = 105km/h*(1.9 h) = 199.5 km

The train traveled 199.5 km

PLEASE HELP Find the product. (a²b³)⁴

cluponka [151]

Answer:

$a^8b^{12}$

Step-by-step explanation:

when you raise an exponent to a power you multiply

Also since the terms inside the parenthesis are multiplied and not added, you don't have to worry about expanding it

$(a^2b^3)^4 = a^{2*4}b^{3*4}=a^8b^{12}$

If y is directly proportional to x squared and y = 3 when x = 2, what is y when x = 8?

Anestetic [448]

Answer:

y = 63

Step-by-step explanation:

y is directly proportional to x²

As given,

when y = 3 => x = 2

So, 3 = 4 - 1

Which means the relation can be written as :-

y = x² - 1

Substituting x = 8

y = (8)² - 1

y = 64 - 1

y = 63

What is the answer a factory adds three red drops an two blue drops of coloring to white paint to make each pint of purple paint

Elan Coil [88]

Answer:

Red = 30 drops

Blue = 20 drops

Step-by-step explanation:

The ratio red to blue is 3 : 2

Sum of ratios = 3 + 2 = 5

Required purple paint = 50 gallons

So,

$Multiplier = \frac{50}{5} = 10$

Now, Red drops = 3×10 = 30

Blue drops = 2×10 = 20

These are expression written as a function of sine, cosine and tangent. The value of x from the given function is 4.29

Trigonometry expression

These are expression written as a function of sine, cosine and tangent.

Given

tanx² - 1/3 = 0

Add 1/3 to both sides

tanx² - 1/3 + 1/3 = 0 + 1/3

tanx² = 1/3

x² = arctan(1/3)

x² = 18.44

x =4.29

Hence the value of x from the given function is 4.29
