Determine the value of k with the specified condition. 1• x²+4x+k=0 the roots are equal

2•kx²-5x_2=0 the roots are equal

3•kx²+4x+6=0 the roots are imaginary

4•x²+5x-k=0 real double roots

5•kx²+3kx+2k+1=0 two equal real roots

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

step-by-step explanation:

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.

24,18t
