Last summer, winky's waterpark kept track of the number of park visitors each day.

Montano1993 [528]

As per the given data 100, 150, 200, 250, 300, 350 the range of the data set is 250.

<h3>What is range?</h3>

It is defined as the difference between the maximum value in the data set to the minimum value in the data set.

We have:

Last summer, Winky's watermark kept track of the number of park visitors each day.

The data given:

100, 150, 200, 250, 300, 350

As we know range is a statistical measure which is the difference between maximum and minimum value.

Range = maximum value in data set—minimum value in data set

Range = 350 - 100 = 250

Thus, as per the given data 100, 150, 200, 250, 300, 350 the range of the data set is 250.

For each function, use the slope formula to calculate the rate of change between the points. In your final answer, include all o

natali 33 [55]

Answer:

m = rate of change of the functions.

1) m = 1/2

2) m = -1

3) m = -2

4) m = 1

5) m = 2

Step-by-step explanation:

Hi there!

For the points (a, f(a)) and (b, f(b)), the rate of change between them, m, is calculated as follows:

m = f(b) - f(a) / (b - a)

Then:

1) f(x) = 1/2 x - 3

f(0) = 1/2 · 0 -3 = -3

f(6) = 1/2 · 6 - 3 = 0

m = f(6) - f(0) /( 6 - 0)

m = 0 - (-3) / 6 = 1/2

2) f(x) = -x

f(-4) = -(-4) = 4

f(2) = -2

m = f(2) - f(-4) /(2 - (-4)

m = -2 - 4 / 2 + 4

m = -6/6

m = -1

3) f(x) = x²

f(-2) = (-2)² = 4

f(0) = 0² = 0

m = f(0) - f(-2) / 0 - (-2)

m = 0 - 4/ 2 = -2

4) f(x) = x³

f(-1) = (-1)³ = -1

f(1) = 1³ = 1

m = f(1) - f(-1) / 1 - (-1)

m = 1 - (-1)/ 2

m = 2/2 = 1

5) f(x) = 2x

f(0) = 2 · 0 = 0

f(4) = 2 · 4 = 8

m = f(4) - f(0) / (4 - 0)

m = 8 - 0 / 4

m = 2

Answers:

k = 13The smallest zero or root is x = -10

===============================

Work Shown:

note: you can write "x^2" to mean "x squared"

f(x) = x^2+3x-10

f(x+5) = (x+5)^2+3(x+5)-10 ... replace every x with x+5

f(x+5) = (x^2+10x+25)+3(x+5)-10

f(x+5) = x^2+10x+25+3x+15-10

f(x+5) = x^2+13x+30

Compare this with x^2+kx+30 and we see that k = 13

Factor and solve the equation below

x^2+13x+30 = 0

(x+10)(x+3) = 0

x+10 = 0 or x+3 = 0

x = -10 or x = -3

The smallest zero is x = -10 as its the left-most value on a number line.

or

m∠EGC=70°

Step-by-step explanation:

we know that

The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite

so

m∠EGC=(1/2)[arc EC+arc DF]

Find the value of x

we have

m∠EGC=(7x+7)°

arc EC=50°

arc DF=10x°

substitute and solve for x

(7x+7)°=(1/2)[50°+10x°]

14x+14=50+10x

14x-10x=50-14

4x=36

x=9

Find the measure of angle EGC

m∠EGC=(7x+7)°

substitute the value of x

m∠EGC=(7(9)+7)°=70°.
