Answer:

1.22474487139

Step-by-step explanation:

x = 3

so if 2x^2 - 1 = 2

add 1 to both equations

2x^2 = 3

next, divide 2 from both sides

x^2 = 3/2

x^2 = 1.5

now find the square root of 1.5

the answer is:

1.22474487139

the slide at the playground has a height of 6 feet.The base of the slide measured on the ground is 8 feet.what is the length of

NemiM [27]

The formula for finding the length is
${a}^{2} + {b}^{2} = {c}^{2}$
All we have to do is plug in the numbers.

${6}^{2} + {8}^{2} = {c}^{2}$
36 + 64 = 100

Since 100 =
${c}^{2}$
we have to find the square root.

$\sqrt{100} = 10$

The length of the slide is 10 feet.

What are the relative minimum and relative maximum values over the interval [−4,4] for the function shown in the graph?

kobusy [5.1K]

Answer:

Relative minimum : -36

Relative maximum : 64

The rate of change is 336 greater

Step-by-step explanation:

Relative minimum are the minimum values in the interval

Looking at the graph, we find the lowest point in the interval

Relative minimum : (-3, -36) and (3,-36) y value -36

Looking at the graph, we find the highest point in the interval

Relative maximum : (0,64) y value 64

Average rate of change = f(x2) - f(x1)

---------------

x2 - x1

f(7) - f(5) 1469 - 549 920

------------- = --------------- = ------- = 460

7-5 7-5 2

f(4) - f(2) 287 - 39 248

------------- = --------------- = ------- = 124

4-2 4-2 2

We need to subtract

460-124

336
