Igoryamba2 years ago
7 0

Answer:

iii. (p - 7)(p - 3)

iv.(x - 8)(x + 4)

Step-by-step explanation:

iii. p² - 10p + 21

= p² - (7 + 3)p + 21

= p² -7p -3p + 21

= p(p - 7) - 3(p - 7)

= (p - 7)(p - 3)

iv. x² - 4x - 32

= x² - (8 - 4)x - 32

= x² - 8x + 4x - 32

= x(x - 8) + 4(x - 8)

= (x - 8)(x + 4)

anu borrows 12,500 as 12% per annum for 3 years at simple interest find the simple interest she has to pay at the end of 3 years
marishachu [46]

Answer:

The interest is 4,500

Step-by-step explanation:

We use the simple interest formula,

I = Prt

where

I = interest

P = principal amount = 12,500

r = interest rate = 12% = 0.12

t = time = 3 years

I = Prt

I = 12,500 × 0.12 × 3

I = 4,500

An evergreen nursery usually sells a certain shrub after 7 years of growth and shaping. The growth rate during those 7 years is
Ne4ueva [31]

Answer:

( 0.6 t^2 + 3t + 11 ) cm

Step-by-step explanation:

dh/dt = 1.2t + 3

at t = 0, h = 11 cm

(a)

dh / dt = 1.2 t + 3

dh = (1.2 t + 3) dt

integrate on both sides

h = 0.6 t^2 + 3t + c    .... (1)

where c is the integrating constant

put t = 0

11 = c

Put in equation (1) , we get

h = ( 0.6 t^2 + 3t + 11 ) cm

Thus, teh height of tree after t years is given by

( 0.6 t^2 + 3t + 11 ) cm.
