17. The variable "a" represents the age of the child
18. The variable "A" represents the adult dosage
19. The prescribed dosage of the medicine for the 6-year-old child is 60 milligrams.
Work: C=6/(6+12)·180
C=6/(18)·180
C=60
Expanded form: 700,000 + 2,000 + 1
The answer is 2990.8 yd
Formula for SA of cylinder: 2*pi*r*h+2*pi*r^2
Formula for radius: diameter/2
Plug the radius, 17, height, 11, and pi, 3.14, into the formula above.
= 2990.8 yd
Answer:
£5 : £25
Step-by-step explanation:
Sum the parts of the ratio, 1 + 5 = 6 parts
Divide the quantity by 6 to find the value of one part of the ratio
£30 ÷ 6 = £5 ← value of 1 part of the ratio, thus
5 parts = 5 × £5 = £25
Thus 1 : 5 = £5 : £25
Answer:
The standard equation is y=ax^2+bx+k and the vertex way is y=a(x-h)(x-h)+x
so the coordinate for x is -b/2a, for your problem a=-4 b=-16 so the coordinate for x is -(-16)/(2*(-4))=-2. Now you have to replace x=-2 in your equation y=-4(-2)^2-16(-2)-11= 5.
The vertex is (-2, 5)
