Hello,
cos (5π/4)=-cos(π/4)=-√2 / 2
sin (5π/4)=-sin(π/4)=-√2 / 2
X=2
f(x)=5x^3+4x^2+x-5
f(2)=5(2)^3+4(2)^2+(2)-5
f(2)=5(8)+4(4)+(2)-5
f(2)=40+16+2-5
f(2)=53
jawaban: 53
Answer:
496.631579
Step-by-step explanation:
Make a proportion
We know that a 377.44 over a number must equal 76%
377.44/x=76/100
Cross multiply
76x=37,744
Divide by 76 on both sides
x=496.631579
So, 76% of 496.631579 is 377.44
Hope this helps!
I didn't quite understand the conversion rate but I believe the answer would be that Keyna will receive 93.75 pounds.
