Answer:
x=1+√5 or x=1−√5
Step-by-step explanation:
F•h(7)=(-7+1)-1=-7 when you have a function that looks like foh, you basically plug the equation of h in for the x value in the equation of f
(7/15)/(3/5)
easy
(a/b)/(c/d)=(a/b)(d/c)
invert and multiply (what it does is it cancels the bottom and makes it one)
(7/15)/(3/5)=(7/15)(5/3)=35/45=7/9
answer is C
7)X=20
8)X=14
9)X=45.83 repeating
10)X=-19
11)X=100
12)X=-25
= 23, 561. 945 cm
Step-by-step explanation:
If the fan does 300 rev per min;
300 rev : 60 sec
x rev : 15 sec
x = 300 * 15 / 60
x = 75 rev
One revolution of the point on the blade is equal to the circumference of the circle with a radius of 10 cm. Therefore;
2πr
2* 3.14 * 10
= 62.83 cm
75 revolution will be;
75 * 62.83 cm
= 4712.39 cm
