Answer:

8 Units (B)

Step-by-step explanation:

The difference of the Y coordinates (since the X coordinates are the same), which are 10 and 2, is 8.

You can also use the distance formula:

$d=\sqrt{(x2-x1)^2+(y2-y1)^2}$

KINNDAAAA need help. Will give Brainly! Need the full equation pls!

Alexxandr [17]

Hey, I’m pretty sure the answer is y=1/2x + 0.

To explain, we can plug the x value into the equation for all of the x values, and we will get our y value.

So the first one,

y=1/2(1) + 0 —> 1/2

The second one,

y=1/2(2) + 0 —> 1

And so forth, the rest of the equations will be correct. I hope that helps ! :D

An equilateral ∆ has sides of length 16 cm. Find the length of an altitude.

inn [45]

The length of the altitude is $8\sqrt{3}$

Explanation:

Let ABC be an equilateral triangle.

It has sides of length 16 cm

Let AD be the altitude of the triangle.

We need to determine the length of an altitude.

Let AC = 16 cm and CD = 8 cm

Let us consider the right angled triangle ADC

Using the Pythagorean theorem, we have,

$AC^2=AD^2+DC^2$

Substituting the values, we get,

$16^2=AD^2+8^2$

$256=AD^2+64$

$192=AD^2$

$8\sqrt{3}=AD$

The length of the altitude is $8\sqrt{3}$

The value of x varies with y and when x=1/3 y=12 write an equationto represent the variation

Virty [35]

Answer:

y = 36x

Step-by-step explanation:

Given that x and y vary directly then the equation relating the is

y = kx ← k is the constant of variation

To find k use the condition x = $\frac{1}{3}$ , y = 12, then

k = $\frac{y}{x}$ = $\frac{12}{\frac{1}{3} }$ = 12 × 3 = 36

y = 36x ← equation of variation

corinne is taking a train into the city. The train travels at a rate of 45 miles per hour. which quantity depends on the other?

lana66690 [7]

Complete Question:

Corinne is taking a train into the city. The train travels at a rate of 45 miles per hour. Which quantity depends on the other?

A. The distance traveled depends on the number of hours traveled.

B. The number of hours traveled depends on the speed of the train.

C. The speed of the train depends on the distance traveled.

D. The speed of the train depends on the number of hours traveled.

Answer:

Corinne is taking a train into the city. The train travels at a rate of 45 miles per hour. The distance traveled depends on the number of hours traveled

Step-by-step explanation:

As we know the velocity can de defined as the rate of change of position of objects in a particular time. The formula is given by,

$\text {velocity}=\frac{\text {distance}}{\text {time}}$

Here, in the question, rate of speed of train is given as 45 miles per hour. if we keep the velocity as constant one, then distance is directly proportionate to the travelled time

$\text {distance}=\text {velocity} \times \text {time}$

If 'v' is constant,

$\text {distance} \propto \text {time}$

By this we can conclude that, the distance travelled by the train depends on the time taken to travel to it. Hence option A would be the correct one.
