Answer:
65.992
Step-by-step explanation:
LM/PL = RN/QR
LM / 113 = 73/ 125
LM =(73/125) * 113
Answer:
6.25
Step-by-step explanation:
she is at 25
she needs to be at 75 which means she needs 50 more feet
at 8 per minute she will reach the depth in 50/8 = 6.25 minutes or 6 minutes and 15 seconds
Answer:
For only the rectangle (that I've coloured in with red) I assume it would be 9 inches squared. However, when adding on the triangles on the side, it would be 9+3+3 = 15
Step-by-step explanation:
(-5+i)/2i
multiply by i/i
(-5+i) *i = -5i +i^2 = -5i -1
2i*i = 2i^2 = 2(-1) = -2
(-1-5i)/-2
1/2 +5/2 *i
f(x) =5-3x
g(x)=x²-1
f(g(x)) = f(x²-1)
replacing x by x²-1 in the function f(x) , we get
f(x²-1) = 5-3(x²-1) = 5-3x²+3 =8-3x²
f(g(x)) =8-3x²
now finding g(f(x))
g(5-3x)
replacing x by 5-3x in the function g(x)
g(5-3x) = (5-3x)²-1
g(5-3x) = 5²-30x +9x²-1 = 9x²-30x +24
g(f(x))= 9x²-30x +24
f(g(x)) =8-3x²
in option third the f(g(x)) is -3x³+8 which is incorrect
