aleksley [76]

Answer:

15 inches

Step-by-step explanation:

Suppose length of original square is L inches.

Now, to form a new square the length increases by 2.5 inches

So, new length=L+2.5 inches

Given that, perimeter of new square =70 inches.

Formula:-

        Perimeter=4*length of square

Therefore 70=4*(L+2.5)

                   70 =4 L+10

                   4 L=60

                  L=15 inches

The relationship between a bacteria population p, in thousands, and time d, in days, since it was measured to be 1,000 can be re
Assoli18 [71]

d = log₂p represents a logarithmic function, The expression log₂(10) tells us when the population reaches 10,000 and the equation 7 = log₂(128) tells us that the population reaches 128,000 in 7 days.

<h3>What is an exponential function?</h3>

An exponential function is in the form:

y = abˣ

Where a is the initial value of y and b is the multiplication factor.

Let p represent the bacteria population in thousand after d days.

Since each day, the bacteria population grows by a factor of 2, hence:

p=2^d

Hence, d = log₂p represents a logarithmic function

The expression log₂(10) tells us when the population reaches 10,000 and the equation 7 = log₂(128) tells us that the population reaches 128,000 in 7 days.

What is the y-intercept of the line 3x – 7y = 42?
Allisa [31]

Answer:

(0, -6)

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

<em>m</em> - slope

<em>b</em> - y-intercept

Step 1: Write standard form

3x - 7y = 42

Step 2: Rewrite in slope-intercept form

  1. Subtract 3x on both sides: -7y = 42 - 3x
  2. Divide both sides by -7: y = -6 + 3/7x
  3. Rewrite: y = 3/7x - 6

Step 3: Find y-intercept

<em>b</em> = -6

Let F (x; y) = xy2i + x2y j. Evaluate ∫F.ds (from c to [infinity]) where C is the upper half of the circle of radius 1 centered
77julia77 [94]

Answer:

The integral \int F \bullets ds is 0.

Step-by-step explanation:

A parameterization of curve C can be:

X (t) = cost 0 <= t <= pi

Y (t) = sint 0 <= t <= pi

r (t) = costi + sintj

r '(t) = -sinti + costj

Fds = [-costsin^3t + sintcos^3t] dt

The integral \int F \bullets ds is given by:

\int _0^{\pi }\left[-costsin^3t + sintcos^3t dt\right]dt

= \int _0^{\pi }-sin ^3tcostdt + \int _0^{\pi }sintcos^3tdt = 0
