Answer:

Option A is correct.

-2 is the rate of change for the interval between –6 and –3 on the x-axis

Step-by-step explanation:

Average rate of change(A(x)) of function f(x) over the interval [a, b] is given by:

A(x) = \frac{f(b)-f(a)}{b-a}          .....[1]

As per the statement:

To find the rate of change for the interval between –6 and –3 on the x-axis.

At x = -6

From the graph:

f(-6) = 6

At x = -3

then;

f(-3) = 0

Substitute these in [1] we have;

A(x) = \frac{f(-3)-f(-6)}{-3+6} = \frac{0-6}{3} = \frac{-6}{3} = -2

Therefore, the  rate of change for the interval between –6 and –3 on the x-axis is, -2

Easy
just find the slope between those 2 points
f(-6)=6
f(-3)=0

slope=rise/run=-6/3=-2
slope is -2
A is answer

Answer:

  y = 3x

Step-by-step explanation:

A proportional relation has the equation ...

  y = kx

To write the desired equation, you need to know the value of k. That can be found from the given information:

  for x = 2, y = 6

  6 = k·2

  3 = k . . . . divide by 2

Now, we know the equation can be written ...

  y = 3x

a jogger ran 3 miles due east of his house. then he ran 5 miles at a heading of 30 east of north. how far is he from his house a
Jobisdone [24]
Let's say her speed was x miles/hour during the first 3 miles runThen, time = distance/speedt1 = 3/x       eq1 In the next 4 miles run, her speed = x-1 miles/hourTime taken:t2 = 4/(x-1)      eq2 Now, total time:t1 + t2 = 1 3/5 hourssubstitute t1 and t2 from eqs. 1 and 2 3/x + 4/(x-1) = 1 3/5=> 3/x + 4/(x-1) = 8/5
=> 3(x-1) + 4x = 8x(x-1)/5=> 35x - 15 = 8x2 - 8x=> 8x2 - 43x + 15 = 0=> (8x-3)*(x-5) = 0=> x = 3/8 or 5 miles/hourx can not be 3/8 miles/hour because in that case, the speed during 4 miles run would be 3/8-1 = negative numberi.e. speed during 3 miles segment = 5 miles/hourand speed during 4 miles segment = 5-1 = 4 miles/hour

A moving trailer with a speed of 70km/h slows down its speed by 15% within 30 seconds. calculate the declaration of the trailer.
antoniya [11.8K]

Answer:

declaration = - 0.55 m/s²

Step-by-step explanation:

The declaration is a negative accelaration.

Therefore:

a = \frac{v-u}{t}

a      = ?

v      = 70 of 15% = 10.5 km/h to m/s = 2.9 m/s

u = 70 km/h to m/s = 19.4 m/s

t = 30 seconds

a = \frac{2.9-19.4}{30}\\

a = - 0.55 m/s²

Someone please help :(
riadik2000 [5.3K]

Answer:

y = -0.2x + 8

Step-by-step explanation:

To write a linear function, calculate the rate of change of the gallon of water leaving the tank and the starting level.

The function will describe the number of gallons over time or (time, gallons).

This means the function has data points (1, 7.8) and (9, 6.2).

Use the rate of change or slope formula to calculate it.

m = \frac{7.8 - 6.2}{1 - 9} =\frac{1.6}{-8} = -0.2

This means that for the formula y = mx+b then m = -0.2.

This also means that after losing 0.2 gallons the first hour it was at 7.8. So the starting value is 8 gallons.

The equation is y = -0.2 x + 8.
