Answer:
:.x=7 ans
Step-by-step explanation:
5x=x+28
5x-x=28
4x=28
x=28/4=7
Answer:
48∛9 ft²
Step-by-step explanation:
Data
The area of the rectangular region is computed as follows:
area = length * width
area = 4 ∛24 * 6 ∛3
area = 4*6* ∛(24*3)
area = 24 * ∛(2³*3*3)
area = 24 * 2∛9
area = 48∛9 ft²
We are given the equation or function <span> y = sqrt (2x + 1). The derivative of the equation is expressed as
</span><span>1. dy/dt = 0.5 *2 *(2x + 1)^-0.5 dx/dt
</span>when x = 4 and dx/dt =3
dy/dt = 0.5 *2 *3*(2*4 + 1)^-0.5
dy/dt = 1
2. <span>dy/dt = 0.5 *2 *(2x + 1)^-0.5 dx/dt
</span><span> If dy/dt = 5, find dx/dt when x = 12.
</span><span> 5= 0.5 *2 (2*12 + 1)^-0.5 dx/dt
dx/dt = 1 </span>
A. 30d
This is because d is the amount of day so if she earns £30 per day the it’s the amount of days x her daily wage =
d x £30 =
30d
(The number always goes first in equations) I hope this helped.
