SCORPION-xisa [38]3 years ago
6 0

Answer:

y= -2x-4

Step-by-step explanation:

(-2,0) = (x_1,y_1) \\ m =  - 2

Substitute values into point slope form

y - y_1 = m(x - x_1) \\ y - 0 =  - 2(x - ( - 2)) \\ y - 0 =  - 2(x + 2) \\ y - 0 =  - 2x - 4

y =  - 2x - 4 + 0 \\ y=  - 2x - 4

Help, I really need help and I've been stuck on this one ^^^
Lostsunrise [7]

Hey there! :)

Let's put all of our facts down first. We know that slope-intercept form is y=mx+b , where m=slope & b is the y-intercept.

So, if we're given the slope and y-intercept, then we can very simply plug those values into slope-intercept form!

Our slope is 4 and our points are (0, -1).

y = mx + by = (4)x + (-1)

Get rid of our parenthesis.y = 4x - 1

So, our equation of the line that passes through (0, -1) and has a slope of 4 is y = 4x - 1

~Hope I helped!~

Under certain conditions, the number of bacteria present in a colony is approximated by f(t) = Age 0.023t, where t is in minutes
AleksandrR [38]

Answer:

  • 5 min: 3,029,058
  • 10 min: 3,398,220
  • 60 min: 10,732,234

Step-by-step explanation:

The given function is evaluated by substituting the given values of t. This requires using the exponential function of your calculator with a base of 'e'. Many calculators have that value built in, or have an e^x function (often associated with the Ln function).

__

<h3>5 minutes</h3>

The number of bacteria present after 5 minutes is about ...

  f(5) = 2.7×10^6×e^(0.023×5) ≈ 3,029,058

<h3>10 minutes</h3>

The number of bacteria present after 10 minutes is about ...

  f(10) = 2.7×10^6×e^(0.023×10) ≈ 3,398,220

<h3>60 minutes</h3>

The number of bacteria present after 60 minutes is about ...

  f(60) = 2.7×10^6×e^(0.023×60) ≈ 10,732,234

Which The following radical functions is graphed below
maks197457 [2]

Answer:

Option A

Step-by-step explanation:

From the graph attached,

Vertical asymptote of the given function → x = -4

Horizontal asymptote → y = 0

Oblique asymptote → None

Therefore, graph that has been given in the picture is,

F(x) = \frac{1}{(x+4)^2}

Option (A) will be the answer.
