The graph below plots a function f(x):

1 answer:

4 0

By definition we have that the average rate of change of the function is given by:
$AVR = \frac{f(x2) - f(x1)}{x2 - x1}
$
Substituting values we have:
$AVR = \frac{100 - 50}{2 - 0}$
Rewriting we have:
$AVR = \frac{50}{2}$
$AVR = 25$
Answer:
If x represents time, the average rate of change of the function f(x) in the first two seconds is 25.

A kite flier wondered how high her kite was flying. She used a protractor to measure an angle of 15∘ from level ground to the ki

Nataly [62]

Answer:

12.9 yd

Step-by-step explanation:

It helps if you draw a triangle. Draw a horizontal segment. That is the ground. Now at the left end start a new segment that goes up to the right at approximately 15 degrees until it its other endpoint directly above the right endpoint of the horizontal segment. Connect these two endpoints. The vertical side on the right shows the height of the kite. The hypotenuse is the string.

For the 15-deg angle, the height of the triangle is the opposite leg, and the string is the hypotenuse. The trig ratio that relates the opposite leg tot he hypotenuse is the sine.

$\sin A = \dfrac{opp}{hyp}$

$\sin 15^\circ = \dfrac{h}{50~yd}$

$(50~yd)\sin 15^\circ = h$

$h = (50~yd)(0.2588)$

$h = 12.9~yd$

identify the coordinates of four points on the line with each given slope and y-intercept. slope=-1 and that y-intercept=8

VladimirAG [237]

Answer:

[-1, 9], [-2, 10], [-3, 11], [1, 7]

Step-by-step explanation:

Starting from the y-intercept of [0, 8], I did rise\run by moving one block north over one block west for the first three coordinates, but retracing back to the y-intercept, I moved one block south over one block east for the last coordinate. It does not matter where you go, as long as you follow the pattern within this rate of change [slope].

I am joyous to assist you anytime.

H(x) = 17 + x/6 h(-18) = ___ x/6 is a fraction please helpp

gayaneshka [121]

Simply plug in the value for x.

If x is equal to -18, then plug in -18 for x.

Example:

f(x) = 15 + x/5.
f(5) = 15 + 5/5.

Then solve the equation.

A function is just something that receives some value and then barfs a value out. This is an IO relationship. (Input/Output).
