Use y = mx + c
M = change in y/change in x
From point (2,4) the y distance from the point to the line is 1, the x distance is 2.
1/2 gives the gradient, a half.
C is the y intercept, where the line crosses the y axis at x = 0, it’s 4.
y = 0.5x + 4

Answer:

y=1/2x+4

Step-by-step explanation:

To find the formula of a line with slope intercept form, you need to know the slope of the line and the y intercept (where the line crosses the y axis, or where x is 0). The y intercept is visibly at (0,4). To find the slope of the line, you need to find how much the line "rises" in a certain amount of "run". You can see that the line moves two to the right for every one unit it moves up, meaning that it has a slope of 1/2. Plugging this into the slope intercept form, or y=mx+b, where m is the slope and b is the y intercept, you get:

y=1/2x+4

Hope this helps!

The tortoise versus the hare: The speed of the hare is given by the sinusoidal function H(t) = sin(t) and the speed of the torto
nata0808 [166]

Answer:

b. The difference in the distance traveled by the tortoise and hare during that time.

Step-by-step explanation:

First the intersection points are found out on the graph. Then the area between the curves is found out.

Putting the values

H(t) = sin(t)

H(t) = sin(1) = 0.01745

T(t) = cos(t),

T(t) = cos(1)= 0.9998

As T(t) ≥ H(t)

Area is found out by taking the integral of it.

Area = Integral ( limit 0 to 0.998)  T(t)-H(t) dt

The difference represents how far the turtle is from the hare.

So it represents the difference in the distance traveled by the tortoise and hare during that time.

You roll a six-sided die twice. What is the probability of rolling an even number and then an odd number?
nlexa [21]

Answer:

C) 1/4

Step-by-step explanation:

Because you have six-sided dice there are 3 odd numbers and 3 even numbers. That means you have a 1/2 for getting either a odd or even number. So we would add 1/2 + 1/2 because you are rolling two times and both have a 1/2 of getting either a odd or even number. 1/2+1/2 = 1./4 which would be your answer.

Hope this helped! Have a good day/night and good luck! Stay safe!!
