hodyreva [135]

Answer:

5/7, 2/3, and 16/21

Step-by-step explanation:

If you put them all under the same denominator you will get 2/3=14/21, 5/7= 10/21, and 16/21. And if you put them in order it is 10/21, 14/21, and 16/21. Hope this helps, let me know if correct!!

10=a/2+7 will give Brainly
Finger [1]
10=a/2 + 7

First subtract 7 from both sides

3=a/2

Next multiple 2 on both sides, so that a is by itself

3(2)=a

A=6

Find the multiplicative inverse of 3 − 2i. Verify that your solution is corect by confirming that the product of
leonid [27]

Answer:

\frac{3}{13} + \frac{2i}{13}

Step-by-step explanation:

The multiplicative inverse of a complex number y  is the complex number z such that (y)(z) = 1

So for this problem we need to find a number z such that

(3 - 2i) ( z ) = 1

If we take z = \frac{1}{3-2i}

We have that

(3- 2i)\frac{1}{3-2i} = 1 would be the multiplicative inverse of 3 - 2i

But remember that 2i = √-2 so we can rationalize the denominator of this complex number

\frac{1}{3-2i } (\frac{3+2i}{3+2i } )=\frac{3+2i}{9-(4i^{2} )} =\frac{3+2i}{9-4(-1)} =\frac{3+2i}{13}

Thus, the multiplicative inverse would be \frac{3}{13} + \frac{2i}{13}

The problem asks us to verify this by multiplying both numbers to see that the answer is 1:

Let's multiplicate this number by 3 - 2i to confirm:

(3-2i)(\frac{3+2i}{13}) = \frac{9-4i^{2} }{13}  =\frac{9-4(-1)}{13}= \frac{9+4}{13} = \frac{13}{13}= 1

Thus, the number we found is indeed the multiplicative inverse of  3 - 2i

Find the surface area of the square pyramid below.
sleet_krkn [62]

Answer:

\displaystyle 762,96\:m.^2 ≈ S.A.

Step-by-step explanation:

\displaystyle a^2 + 2a\sqrt{\frac{a^2}{4} + h^2} = S.A. \\ \\  14^2 + 2[14]\sqrt{\frac{14^2}{4} + 19^2} = S.A. \\ \\ 196 + 28\sqrt{\frac{196}{4} + 361} ≈ 762,9567885 ≈ 762,96

I am joyous to assist you anytime.
