How to round $45.71 to the nearest dollar

2 answers:

8 0

The answer is 46.00 because when rounding if the number is 5 and high then you round up and to the left. Example 23.621 round to the nearest whole number 6 is high than 5 so the 3 turns to a 4 so the answer is 24.000

Since .7 is above 5.

$45.71 would turn to $46.00.

You would round 45... the 5 to 6...

To be $46

The equation 4s = 33.4 models a constant rate situation. Drag and drop the value of 2s in the box. a 16.7

yKpoI14uk [10]

The answer to the equation you posted The equation 4s = 33.4 models a constant rate situation. what is the value of 2s is:
to make the given equation 4s = 33.4 to 2s, divide the whole equation by 2

1/2 ( 4s = 33.4)
4s/2 = 33.4/2
2s = 16.7

Can someone please explain this to me? Thanks!

Answer: Choice D

$\displaystyle F\ '(x) = 2x\sqrt{1+x^6}\\\\$

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

Explanation:

Let g(t) be the antiderivative of $g'(t) = \sqrt{1+t^3}$ . We don't need to find out what g(t) is exactly.

Recall by the fundamental theorem of calculus, we can say the following:

$\displaystyle \int_{a}^{b} g'(t)dt = g(b)-g(a)$

This theorem ties together the concepts of integrals and derivatives to show that they are basically inverse operations (more or less).

So,

$\displaystyle F(x) = \int_{\pi}^{x^2}\sqrt{1+t^3}dt\\\\ \displaystyle F(x) = \int_{\pi}^{x^2}g'(t)dt\\\\ \displaystyle F(x) = g(x^2) - g(\pi)\\\\$

From here, we apply the derivative with respect to x to both sides. Note that the $g(\pi)$ portion is a constant, so $g'(\pi) = 0$

$\displaystyle F(x) = g(x^2) - g(\pi)\\\\ \displaystyle F \ '(x) = \frac{d}{dx}[g(x^2)-g(\pi)]\\\\\displaystyle F\ '(x) = \frac{d}{dx}[g(x^2)] - \frac{d}{dx}[g(\pi)]\\\\ \displaystyle F\ '(x) = \frac{d}{dx}[x^2]*g'(x^2) - g'(\pi) \ \text{ .... chain rule}\\\\$

$\displaystyle F\ '(x) = 2x*g'(x^2) - 0\\\\ \displaystyle F\ '(x) = 2x*g'(x^2)\\\\ \displaystyle F\ '(x) = 2x\sqrt{1+(x^2)^3}\\\\ \displaystyle F\ '(x) = \boldsymbol{2x\sqrt{1+x^6}}\\\\$

What is the length of the diagonal, ddd, of the rectangular prism shown below?

ad-work [718]

Answer:

≈ 9.6 units

Step-by-step explanation:

Refer to attachment

The diagonal d is the hypotenuse of right triangle with sides of 5 and a

The line a is the hypotenuse of the right triangle with the sides of 2 and 8.

So, as per Pythagorean theorem:

d² = 5² + a²
d²= 5² + 2²+ 8² = 25 + 4 + 64 = 93
d² = 93
d = √93
d ≈ 9.6 units (rounded to the nearest tenth)

A Farm raises pigs and chickens. The farmer has a total of 66 animals. One Day he Counts the legs of all his animals and realize

Bogdan [553]

Answer: Pigs = 21

Chicken = 45

Step-by-step explanation:

Let the pigs be represented by p

Let the chicken be represented by c.

From the question,

p + c = 66

4p + 2c = 174

4 × ( p + c = 66)

1 × (4p + 2c = 174)

4p + 4c = 264

- 4p + 2c = 174

2c = 90

c = 90/2 = 45

There are 45 chickens

Simce the farmer has a total of 66 animals, the number of pigs will be:

= 66 - 45

= 21 pigs

Hello!

You read scientific notation by moving the decimal that amount of spaces next the the 10

1.263 * 10^3

You move the decimal over 3 places

1.263 * 10^3 = 1263

The answer is 1.263 * 10^3

Hope this helps!
