Make k the subject for 3t = 7k/13 - 17 and 7k = 4k/3t - 11t

Mathematics
1 answer:

A)

3t = 7k/13  - 17

3t + 17 = 7k/13

13*(3t + 17) = 7k

7k =  13*(3t + 17)

7k = 39t + 221

k = (39t + 221) / 7

b)

7k = 4k/3t -  11t

11t = 4k/3t - 7k              LCM = 3t

11t =  (4k - 21kt) / 3t

11t*3t = (4k - 21kt)

33t² = k(4 - 21t)

33t² /(4 - 21t)  = k

k =  33t² /(4 - 21t)

I hope this helps.

GarryVolchara [31]

Answer:

114.3cm^3

Step-by-step explanation:

Square Pyramid Formulas derived in terms of side length a and height h: Volume of a square pyramid

V = (1/3)(Base area of a square)(Height of the square pyramid).

V = (1/3)area^{2}hight

Area of the square

A = 7 x 7

A = 49

V = (1/3)49 x 7

V = (1/3)343

V = 114.(a repeating term)3

since we rounded

V = 114.3cm^3

Given an exponential function for compounding interest, A(x) = P(1.02)x, what is the rate of change?
Sedbober [7]
A(x) = P(1.02)^x
A(x) = P(1 + 0.02)^x
A(x) = P(1 + r)^x

Therefore rate of change = 0.02 = 2%
