7 3/4 subtracted by 2 2/5
show your work
Answer:
5 7/20
Step-by-step explanation:
basically, you are going to want to turn these into improper fractions
7 3/4 = 28/4 + 3/4
= 31/4 (no further simplification)
2 2/5 = 10/5 + 2/5
= 12/5
now get common denominator to subtract
31/4 - 12/5
155/20 - 48/20 = 107/20
if you want this back into mixed fraction then convert
107/20 = 5 7/20
What is Cos^-1( -sq2/2)? Pleaseee help ASAPOL
Answer:
s cos^(-1)(-(q^2 s)/2) + sqrt(4 - q^4 s^2)/q^2 + constant
Step-by-step explanation:
Take the integral:
integral cos^(-1)(-(q^2 s)/2) ds
For the integrand cos^(-1)(-(q^2 s)/2), substitute u = -(q^2 s)/2 and du = -q^2/2 ds:
= -2/q^2 integral cos^(-1)(u) du
For the integrand cos^(-1)(u), integrate by parts, integral f dg = f g - integral g df, where
f = cos^(-1)(u), dg = du, df = -1/sqrt(1 - u^2) du, g = u:
= -(2 u cos^(-1)(u))/q^2 + 2/q^2 integral-u/sqrt(1 - u^2) du
Factor out constants:
= -(2 u cos^(-1)(u))/q^2 - 2/q^2 integral u/sqrt(1 - u^2) du
For the integrand u/sqrt(1 - u^2), substitute p = 1 - u^2 and dp = -2 u du:
= -(2 u cos^(-1)(u))/q^2 + 1/q^2 integral1/sqrt(p) dp
The integral of 1/sqrt(p) is 2 sqrt(p):
= (2 sqrt(p))/q^2 - (2 u cos^(-1)(u))/q^2 + constant
Substitute back for p = 1 - u^2:
= (2 sqrt(1 - u^2))/q^2 - (2 u cos^(-1)(u))/q^2 + constant
Substitute back for u = -(q^2 s)/2:
Answer: = s cos^(-1)(-(q^2 s)/2) + sqrt(4 - q^4 s^2)/q^2 + constant

Find f(x) and g(x) so that the function can be described as y = f(g(x)).
y = Four divided by x squared. + 9
a) f(x) = x + 9, g(x) = Four divided by x squared.
b)f(x) = x, g(x) = Four divided by x. + 9
c)f(x) = One divided by x., g(x) = Four divided by x. + 9
d)f(x) = Four divided by x squared., g(x) = 9
the answer is Y/g
y=fgx
y/g=fx,which mines f(x)=y/g

A nurse wants to simulate the number of male and female births at the hospital where she
works using a random digit table.
Which of the following best simulates this situation?
Answer:
Let the digits 0,1,2,3 and 4 represent the birth of a boy, and let digits 5,6,7,8, and 9 represent the birth of a girl. Use a table of random digits. Choose the first 10 digits in the table and record the number of boy and girl births. Continue to choose batches of 10 digits for a total of 100 times, recording the number of boy and girl births.

16 is the geometric mean of 8 and what other number n
9514 1404 393
Answer:
32
Step-by-step explanation:
The geometric mean relation says ...
16 = √(8n)
256 = 8n . . . . . square both sides
32 = n . . . . . . . . divide by 8
The other number n is 32.

Cody bought two pairs of gloves and four hats for $43. Tori bought two pairs of gloves and two hats for $30. What are the prices for the gloves and hats? Write a system of equations!
Answer:
2g + 4h = 43
2g + 2h = 30
Step-by-step explanation:
Answer:
pairs of gloves = x
hats = y
2x + 4y = 43
2x + 2y = 30
hats = $6.50
gloves = $8.50
Step-by-step explanation:
use the elimination method to solve this system.
subtract the first equation by the second.
2x + 4y = 43
- 2x + 2y = 30
--------------------
2y = 13
y = 6.5
plug in the y value to find x
2x + 4 (6.5) = 43
2x + 26 = 43
2x = 17
x = 8.5
