Answer:
You would need $23.87 if you wanted to by 7 books
Step-by-step explanation:
divide 6 by 20.46 and you get $3.41 so multiply $3.41 by 7 and you end up with $23.87.
Answer: 287/8
34 4/7 and 34 9/12
Step-by-step explanation:
The other fractions are less than 1/2. 287/8 works out to 35 7/8
Answer:
commutative property
Explanation:
This is known as the commutative property of addition (and multiplication).
An easy way to remember the property is that the two elements commute, or exchange places, or that one element commutes from one side of the operation to the other, like a commuter (passenger) on a commuter train.
a + b = b + a
The period of cos is 2π
so the period of cos(4x + π) is 2π/4 = π/2
cos(4x + π) = -cos4x => <span>-3 cos(4x + π) + 6 = 3cos4x + 6
phase shift may be [-</span>π/4,π/4]
amplitude is [-3,3]
Answer:
x=34
Step-by-step explanation:
1. formula for Pythagorean Theorem for right trangles is <u>a^2+b^2=c^2</u>
2. a=30 and b=16, so (30)^2+(16)^2=c^2
3. (30)^2=900 and (16)^2=256
4. 900+256=1156
5. 1156=c^2
6. ![\sqrt{1156} =\sqrt{c^2}](https://tex.z-dn.net/?f=%5Csqrt%7B1156%7D%20%3D%5Csqrt%7Bc%5E2%7D)
7. the square root of 1156 is 34, so c=34
8. The missing side of the triangle, labeled as "x<em>"</em> is 34
