Un plop a crescut intre doua blocuri B1 si B2 Inaltimea blocului B1 este de 10m, iar inaltimea blocului B2 este de 15m. varful plopului, O, apartine dreptelor CD si EF. Atunci, inaltimea plopului este egala cu?

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

11

step-by-step explanation:

32.50-7.50=25

225/25=11
