What is the simplified form of the expression square root of -64
we have
![\sqrt[]{-64}](https://tex.z-dn.net/?f=%5Csqrt%5B%5D%7B-64%7D)
Remember that
64=2^6
and
i^2=-1
substitute
![\sqrt[]{-64}=\sqrt[]{(-1)(2^6)}=\sqrt[]{i^2\cdot2^6}=2^3i=8i](https://tex.z-dn.net/?f=%5Csqrt%5B%5D%7B-64%7D%3D%5Csqrt%5B%5D%7B%28-1%29%282%5E6%29%7D%3D%5Csqrt%5B%5D%7Bi%5E2%5Ccdot2%5E6%7D%3D2%5E3i%3D8i)
<h2>option B</h2>
Answer:
a = 72° b = 88°
Step-by-step explanation:
We know in the cyclic quadrilateral opposite angles are supplementary so
a + 108° = 180° { being opposite angles of cyclic quadrilateral }
a = 180° - 108°
a = 72°
b + 92° = 180° { being opposite angles of cyclic quadrilateral }
b = 180° - 92°
b = 88°
The x values are the first one (and correlate to the domain), so we just have to find the smallest and largest number, which are -62.6 and 84.6 by just looking through the data
Answer:
convert 2/5 to a decimal, which is 0.4
multiplying a value by 10 means you should move the decimal point one unit to the right
so 10 x 2/5 = 4
Step-by-step explanation:
Answer:
Step-by-step explanation:
10%=325
1%=32.5
325-32.5=292.5
3250+3542.5=3542.50£
So 9% increase.
