Answer:

  68

Step-by-step explanation:

The number of chips tested is the integral of the rate over the specified time interval: t = 2 to 6.

  \displaysyle n=\int_2^6{-3t^2+16t+5}\,dt=\left.-3\dfrac{t^3}{3}+16\dfrac{t^2}{2}+5t\right|_2^6\\\\=-(6^3-2^3) +8(6^2-2^2)+5(6-2)=-(216-8)+8(32) +5(4)\\\\=-208+256+20=\boxed{68}

The technician can test 68 chips in that time period.

A. -11÷4

B. 11 ÷ (-4)

D. -11/4

E. 11/-4

What is the value of X?
svet-max [94.6K]

Answer: 71 degrees.

Step-by-step explanation:

Due to the triangle being isosceles (Two sides are equal), we can assume that the angles will also be equal.

You can take 180 (The total of a triangle) and subtract by the known degree

180 - 38 = 142

Now we divide 142 by two, ONLY because this is case; both angles will be the same degree.

142 / 2 = 71

Therefore; x = 71

I could use some help , i really cant do geometry :(
Gelneren [198K]

Answer:

I am not sure but for

CAE it is 65˚

CBD it is 65˚

Step-by-step explanation:

x+40=3x-10

Move the 3x to the other side by subtracting by 3x on both sides

x-3x+40=3x-3x-10

The equation now looks like this:

-2x+40=-10

Move 40 to the other side by subtracting 40 both sides:

-2x+40-40=-10-40

-2x=-50

Divide by -2 on both sides:

-2x/-2=-50/-2

x=25

Since we found out what x is we can replace x in both CAE and CBD:

For CBD: 25+40 is 65

For CAE: 3(25)-10 is 65
