Explain how to multiply square roots

2 answers:

7 0

When multiplying square roots, we simply multiply the values inside the square roots. So for example, let's look at the problem below.

√a · √a

So the square root of a times the square root of a equals the square root of a time a or √a² and the square root of a² is simply a.

Answer:

To multiply square roots, first multiply the radicands, or the numbers underneath the radical sign. If there are any coefficients in front of the radical sign, multiply them together as well. Finally, if the new radicand can be divided out by a perfect square, factor out this perfect square and simplify it.

A spinner and 4 cards are shown below:

yan [13]

Answer: 1 over 20

Step-by-step explanation: If the spinner has 5 parts to it at purple is one of those parts then the spinner has a 1/5 chance of it landing there.

If there are 4 cards and 1 of them are pink then there is a 1/4 chance of picking pink(if done randomly)

So if we mutiply 1/4 and 1/5, we get 1/20

That is how I arrived at my answer of 1 over 20

A quadratic function is given. f(x) = 1 + x − 7 x2 (a) Use a graphing device to find the maximum or minimum value of the quadrat

Virty [35]

Answer:

a) $P (x,y) \approx (0.1,1.05)$ , b) $P(x,y) = (0.07,1.04)$ .

Step-by-step explanation:

a) The graphic is enclosed to the problem. By visual inspection, an absolute maximum is found.

$P (x,y) \approx (0.1,1.05)$

b) The exact method consists in the application of the First and Second Derivative Tests. First and second derivatives are, respectively:

$f'(x) = 1 - 14\cdot x$

$f''(x) = -14$

The First Derivative Test consists in equalizing the first derivative to zero and solving the expression:

$1 - 14\cdot x = 0$

$x = 0.07$

According to the second derivative, the critical point leads to a maximum. The remaining component is determined by evaluation the polynomial:

$y = 1 +0.07-7\cdot (0.07)^{2}$

$y = 1.04$

The exact solution is $P(x,y) = (0.07,1.04)$ , indicating that graphic solution leads to a good approximation.

What is the volume of a square pyramid with a base length of 6cm and a height of 9cm?

emmainna [20.7K]

Answer:
Volume = 108 cm ³

Explanation:
For a square pyramid, the volume can be calculated as follows:
Volume = $\frac{1}{3}$ * area of base * height
Volume = $\frac{1}{3}$ * side² * height
We have:
side length = 6 cm
height = 9 cm
Therefore:
Volume = $\frac{1}{3}$ * 36 * 9 = 108 cm ³

Hope this helps :)
