Answer: 26.6
Step-by-step explanation:
r = 12 5(12) = 60 | s = 4 8.35(4) = 33.4 | Now subtract both total number = 33.4 - 60 = 26.6
I liked using fractions for this type of question, I just find it easier, so in this case 20% is 1/5. That means that £45 is 4/5, so you have to divide 45 by 4 to get 1/5 of the original amount. 45 ÷ 4 = 11.25. Then, you just multiply 11.25 by 5 to get £56.25, which should be the answer. Hope this helped!
Answer:
16x^2 - 25
(4x - 5)(4x + 5)
Step-by-step explanation:
f(x) has the smallest minimum. The minimum value of f(x) is -3
The largest sin(x) can get is 1.
This applies to sin(2x-pi) as well. So f(x) is as small as -5*(1)+2 = -5+2 = -3.
You can see this each time the red curve bottoms out at y = -3.
The smallest that g(x) can get is y = -2 as shown at the vertex (3,-2)
The smallest that h(x) can get is y = 3 as shown by the point (1,3)
See the attachment for a visual comparison of the three functions.
