The rate at which an assembly line workers efficiency E (expressed as a percent) changes with respect to time t is given by E'(t
zavuch27 [327]

By the fundamental theorem of calculus,

E(t)=E(1)+\displaystyle\int_1^t E'(u)\,\mathrm du

So we have

E(t)=92+\displaystyle\int_1^t(75-6u)\,\mathrm du

E(t)=92+(75u-3u^2)\bigg|_1^t

E(t)=20 + 75 t - 3 t^2

Can someone please help me I really need help help me thank you
harkovskaia [24]

Answer:

<h2><em><u>A to C = 25 </u></em></h2><h2><em><u>A to B = 13 </u></em></h2><h2><em><u>C to B = 37 </u></em></h2><h2><em><u></u></em></h2>

Step-by-Step Explanation:

<em><u>Perimeter</u></em> = 75

<em><u>Sides:</u></em>

2x + 3

3x + 4

2x - 9

<h2 /><h2><em><u>1. Equal the sides added together to the perimeter</u></em></h2>

75 = 2x + 3 + 3x + 4 + 2x - 9

<h2><em><u>2. Simplify Like terms</u></em></h2>

2x + 3 + 3x + 4 + 2x - 9  = 7x - 2

<h2><em><u>3. Place the equation back together</u></em></h2>

75 = 7x - 2

<h2><em><u>4. Isolate the variables and numbers</u></em></h2>

75 = 7x - 2

+2        +2

77 = 7x

<h2><em><u>5. Simplify the equation</u></em></h2>

77 = 7x

/7     /7

<h2><em><u>11 = x </u></em></h2>

<h2><em><u>6. Substitute the value of x into the side lengths.</u></em></h2>

2x + 3 = 2(11) + 3 = 22 + 3 = <em><u>25</u></em>

3x + 4 = 3(11) + 4 = 33 + 4 = <em><u>37</u></em>

2x - 9 = 2(11) - 9 = 22 - 9 = <em><u>13</u></em>

Kaylis [27]

Answer:

Step-by-step explanation:

The volume of a cube is s*s*s or s^3 where s = the length of a side (2 in this case).

V = s^3

V = 2^3

V = 2*2*2

V = 8 cu in or 8 in^3

Answer: The slope is 2 -Please mark brainliest

1. Find the X and Y values of each point

X1: 1

X2: -1

Y1: 3

Y2: -1

2. Subtract X1 from X2 and Y1 from Y2

Y: -1-3=-4

X: -1-1=-2

3. Divide the X value by the Y value

-4/-2=2

The slope of the line shown on the coordinate plane is 2.

damaskus [11]

oceans, tropical plants, Europe

Step-by-step explanation:

Fossils on continents that are now separated by oceans support the theory of continental drift. Continents closer to the equator have warmer climates, yet fossils of tropical plants have been found on islands near the North Pole. This supports the idea that islands drifted from the equator. Coal fields in Europe match those found in North America, supporting the theory of continental drift.

The theory of continental drift was proposed by Alfred Wegener in the early part of 20th century. He suggested that the continents have once been joined together as a single landmass but have drifted to their current positions today.

  • Fresh water fossils of organisms like Mesosaurus was found in parts of South America and Southern Africa. These organisms could not have swim between the oceans since they are localized to freshwater environments.
  • Tropical plants have also been found in regions of the north pole.
  • Coal fields in north America correlated with those in South America and this provided support to the theory of continental drift by Wegener.
  • He also fitted the the world into a giant puzzle to support his claim.
