Marina CMI [18]2 years ago

Answer:

37,500 meters long

Step-by-step explanation:

The tape plays at 0.048 meters per second. First, let's find the number of seconds in 30 minutes.

  • 30 minutes
  • 60 seconds * 30
  • 1800 seconds

The tape plays at 0.048 meters per second for 1800 seconds

The equation is:

  • 0.048x = 1800
  • x = 1800/ 0.048
  • x = 37,500

The tape is \boxed{\text{37,500 meters long}}

Find the length of "a", to<br> the nearest tenth, using<br> the Pythagorean Theorem.<br> Enter
bearhunter [10]

Answer:

\sqrt{28} \approx 5.3

Step-by-step explanation:

The Pythagorean Theorem says if you have a right triangle, then relationship between the three sides is the sum of the square of each leg is the hypotenuse squared.

So a^2+b^2=c^2

where a and b are legs and c is the hypotenuse.

Plug in your a,b, and c. In this case it is a,6, and 8.

This means we have

a^2+6^2=8^2

Simplify where you can before we begin the solving (the moving around of things to other sides).

a^2+36=64

Now time for the solving. We are first going to get a^2 by itself.

To do this, we just need to subtract 36 on both sides giving us:

a^2=64-36

a^2=28

Now to get rid of the square on a, just square root both sides:

a=\sqrt{28}.

If f(x) = 2х2 +1 and g(x) = х2 -7, find (f-g)(x).
Nookie1986 [14]

Option A

If  f(x) = 2x^2 + 1 and g(x) = x^2 - 7 then (f - g)(x) = x^2 + 8

<em><u>Solution:</u></em>

Given that f(x) = 2x^2 + 1 and g(x) = x^2 - 7

To find: (f - g)(x)

We know that,

(f – g)(x) = f (x) - g(x)

Let us substitute the given values of f(x) and g(x) in above formula,

(f - g)(x) = 2x^2 + 1 - (x^2 - 7)

For solving the brackets in above expression,

There are two simple rules to remember:

When you multiply a negative number by a positive number then the product is always negative.

When you multiply two negative numbers or two positive numbers then the product is always positive.

So the expression becomes,

(f - g)(x) = 2x^2 + 1 -x^2 + 7

Combining the like terms,

(f - g)(x) = 2x^2 - x^2 + 1 + 7\\\\(f - g)(x) = x^2 + 8

Thus option A is correct
