PLEASE HELP solve x^2 - 64 = 0

Mathematics
1 answer:
scoray [572]3 years ago
3 0

Answer:

x = -8 and x = 8

Step-by-step explanation:

x^2 - 64 = 0                     Our first step is to factor

(x + 8)(x - 8) = 0          Now use zero product property to help solve for x

x + 8 = 0            x - 8 = 0

x = -8                 x = 8

Hope this helps!

20 POINTS!!! I GIVE BRAINLIEST PLEASE HELP!!!!A circle with a circumference of approximately 15.71 inches drawn inside a square,
Oksi-84 [34.3K]

answer:

5.002 inches

step-by-step explanation:

  • find the diameter of the circle
  • the diameter is the side length of the square since the sides of it are touching the circle

c = 2πr

  • c stands for circumference
  • π stands for pi (or 3.14)
  • r stands for radius

- plug in the values given to find the diameter

c = 2πr

15.71 = 2(3.14)r

15.71 = 6.28r

r = 2.501 (rounded or estimated)

  • now that we have the radius, we can find the diameter by multiplying by 2, since diameter is two times bigger than the radius

diameter = 5.002 (estimated)

  • now, that will be the side length because the diameter = the side length

Find a power series representation of e^x sin(x)
liberstina [14]
The Taylor series is defined by:
f(x) = \sum \frac{f^n (a)}{n!} (x-a)^n

Let a = 0.
Then its just a matter of finding derivatives and determining how many terms is needed for the series.

Derivatives can be found using product rule:
f^n (x) = e^x g^{n-1} (x) + e^x g^n (x)  \\ g^0 (x) = sin x

Do this successively to n = 6.
f^1 (x) = e^x (sinx +cos x) \\ f^2 (x) = e^x (2cos x)  \\ f^3 (x) = e^x(2cos x - 2sin x)  \\ f^4 (x) = e^x (-4 sin x)  \\ f^5 (x) = e^x(-4sinx -4cos x) \\ f^6(x) = e^x(-8cos x)

Plug in x=0 and sub into taylor series:
e^x  sin x = x+x^2 +\frac{x^3}{3} -\frac{x^5}{30}-\frac{x^6}{90}...

If more terms are needed simply continue the recursive derivative formula and add to taylor series.
