While testing a new vaccine, a lab technician noticed that the number of bacteria reduced by half every minute. How long does it

ANTONII [103]

As we know that
x=x0*[1/2]n
putting the values
375=3000*[1/2]n
375/3000=[1/2]n
1/8=[1/2]n
simplify
[1/2]3=[1/2]n
by cancelling them
so n=3
so it will take 3 minutes
hope it helps

PLEASE HELP... VERY URGENT... WILL GIVE BRAINLIEST!!!

lakkis [162]

Answer:

Step-by-step explanation:

a) Pythagorean theorem,

altitude² + base² = hypotenuse²

h² + (w² - 1)² = (w² + 1)²

h² = (w² + 1)² - (w² - 1)²

{Compare with (a + b)² - (a -b)² = 4ab where a =w² & b = 1}

h² = 4*w²*1

h² = 4w²

$h=\sqrt{4w^{2}} = \sqrt{2*2*w*w} \\\\\\h = 2w$

b) Area of triangle = $\frac{1}{2}b*h$

$=\dfrac{1}{2}*(w^{2}-1) *2w\\\\= (w^{2}-1)*w = w^{2}*w - 1*w\\\\=w^{3}-w$

c) w =2

Area of triangle = 3w = 3*2 = 6
