Answer:
(3√26, 0)
Step-by-step explanation:
Finish your work by evaluating the sine and cosine. The imaginary part corresponds to the y-coordinate in (x, y) form.
3√26(cos(360°) +i·sin(360°)) = 3√26(1 +0i)
In rectangular form, that is ...
(3√26, 0)
A^7. "A" raised to the power of 7 would be the exponential form. hope this helps.
Answer:
x=27
Step-by-step explanation:
To evaluate the expression: ![[(3^{-5})(3^4)]^3](https://tex.z-dn.net/?f=%5B%283%5E%7B-5%7D%29%283%5E4%29%5D%5E3)
Step 1: Innermost group, apply the product of powers (
Therefore:
We then have:
![=[3^{-1}]^3](https://tex.z-dn.net/?f=%3D%5B3%5E%7B-1%7D%5D%5E3)
Step 2: Apply the power of a power
![[3^{-1}]^3=3^{-1 \times 3} =3 ^{-3}](https://tex.z-dn.net/?f=%5B3%5E%7B-1%7D%5D%5E3%3D3%5E%7B-1%20%5Ctimes%203%7D%20%3D3%20%5E%7B-3%7D)
Step 3: Apply the negative exponent
Step 4: Simplify
Therefore, the value of x in the simplified expression is 27.
Answer:
26.
Step-by-step explanation:
Given, BD is a median. As it divides the AC equally, that's why it will AD=CD. Given, AD= 6x+10 and CD= 2x+12
Now, AD= CD
or, 6x+10=2x+12
or, 6x-2x= 12-10
or, 4x= 2
or, x= 1/2
So the value of x is 1/2. As BD divided AC equally, both AD and CD will be equal and AD+CD= AC.
So, 6x+10+2x+12= AC
or, 8x+22= AC
or, 8 X (1/2) + 22= AC
or, 4+22 = AC
or, AC= 26.=
