Find the geometric mean of 2 and 3

1 answer:

7 0

The first step in solving this problem is taking 2 and 3 and multiplying them (2 * 3 = 6) .
Now, for the second step, we will cube it. Since there are 2 numbers, we are going to use the 2nd root (2sqrt(6)) This will give us: 4.89897948557 or 5 if you would round it. This would be the Geometric Mean.

I need to know the answer I’m working on rational numubers

lesya [120]

Answer:

Fraction Form: $\frac{11}{24}$

Decimal Form: 0.4583

Step-by-step explanation:

Apply the fraction rule: $\frac{-a}{b} = - \frac{a}{b}$

$\frac{-5}{12} = - \frac{5}{12}$

$- \frac{5}{12} + \frac{7}{8}$

Least Common Multiple (LCM) of 12 and 8: 24

$- \frac{5}{12} x \frac{2}{2} = - \frac{10}{24} \\\\\frac{7}{8} x \frac{3}{3} = \frac{21}{24} \\\\- \frac{10}{24} + \frac{21}{24}$

Apply the fraction rule:

$\frac{a}{c} + \frac{b}{c}= \frac{a + b}{c}\\\\\frac{-10 + 21}{24} \\\\-10 + 21 = 11\\\\\frac{11}{24}$

Which angle is an x-intercept for the function y = cos(1)<br> A.0<br> B.2<br> C. £<br> D. 2£

noname [10]

Answer: C. $\pi$

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

Explanation:

The x intercept always occurs when y = 0.

Use the unit circle to determine that $\cos(\theta) = 0$ when $\theta = \frac{\pi}{2} \text{ and } \theta = \frac{3\pi}{2}$

So if $x = \pi$ , then we have

$y = \cos\left(\frac{1}{2}x\right)\\\\y = \cos\left(\frac{x}{2}\right)\\\\y = \cos\left(\frac{\pi}{2}\right)\\\\y = 0\\\\$

which shows us that $(\pi, 0)$ is the location of one of the infinitely many x intercepts for this function.

Find the value for f(x) = 22

Varvara68 [4.7K]

Answer:

Step-by-step explanation:

Another way to solve would be to distribute first:

22 = 2(x + 6)

22 = 2x + 12

Subtract 12:

22 - 12 = 2x - 12

10 = 2x

Divide by 2:

10 / 2 = 2x / 2

5 = x

Jaden deposited $9000 in a savings account with a simple interest .Two years later the account held up $10,440 what is the inter

Ber [7]

Answer:

Step-by-step explanation:

The simple interest formula is

I = Prt, where I is the interest earned, P is the initial investment, r is the interest rate in decimal form, and t is the time in years. We have that after 2 years, 9000 has turned into 10440. That means that the total interest earned was 10440 - 9000 = 1440

I = 1440

P = 9000

r = ?

t = 2

Filling in we have

1440 = 9000(r)(2) and

1440 = 18000r so

r = .08

As an interest rate, we multiply this by 100 to get 8%
