Use the intermediate value theorem to prove that there is a positive number c such that c2 = 2.

schepotkina [342]

So lets try to prove it,

So let's consider the function f(x) = x^2.

Since f(x) is a polynomial, then it is continuous on the interval (- infinity, + infinity).

Using the Intermediate Value Theorem,

it would be enough to show that at some point a f(x) is less than 2 and at some point b f(x) is greater than 2. For example, let a = 0 and b = 3.

Therefore, f(0) = 0, which is less than 2, and f(3) = 9, which is greater than 2. Applying IVT to f(x) = x^2 on the interval [0,3}.

What is the solution set to, "Katie wants to collect over 100 seashells. She already has 34 seashells in her collection. Each da

Anastaziya [24]

Answer:

Katie will collect more than 100 seashells in 5 and a half days.

Step-by-step explanation:

Katie already has 34 seashells in her collection.

Each day, she finds 12 more seashells on the beach.

Let x be the number of days Katie is collecting seashells.

In x days, she will collect 12x seashells.

In total, she will collect $34+12x$ seashells.

Katie wants to collect over 100 seashells, so

$34+12x> 100$

Solve this inequality. Subtract 34:

$34+12x-34>100-34\\ \\12x>66\\ \\2x>11\\ \\x>5 \dfrac{1}{2}$

Katie will collect more than 100 seashells in 5 and a half days.

Cos(-170°) = _____<br><br> -cos10°<br> cos10°<br> cos(-10°)

Lera25 [3.4K]

Answer:

Step-by-step explanation:

cos is positive at first and fourth quadrant

so, cos (-x) = cos (x)

also, cos(180-x) = -cos x

cos (180+x) = -cos x

cos (-170°) = cos (170°)

cos(170°) = cos (180° - 10°)

= - cos 10°
