The teacher asked 4 students to measure 4 different objects. Here are the results
posledela

Answer:

<em>Student 3 had the greatest percentage error.</em>

Step-by-step explanation:

<u>Student 1</u>

Actual length = 50in

Measured length = 49in

Error = 50 - 49 = 1

Error% = 1/50 × 100

= 1 × 2

= 2%

<u>Student</u><u> </u><u>2</u>

Actual length = 100cm

Measured length = 110cm

Error = 100 - 110 = 10

Error% = 10/100 × 100

= 10 × 1

= 10%

<u>Student</u><u> </u><u>3</u>

Actual length = 2cm

Measured length = 2.5cm

Error = 2 - 2.5 = 0.5

Error% = 0.5/2 × 100

= 0.5 × 50

= 25%

<u>Student</u><u> </u><u>4</u>

Actual length = 10ft

Measured length = 9½ft

Error = 10 - 9½ = ½

Error% = ½/10 × 100

= ½ × 10

= 1 × 5

= 5%

Evaluate ModifyingBelow Integral from nothing to nothing With Upper C xy dx plus left parenthesis x plus y right parenthesis dy
Zepler [3.9K]

Parameterize the curve by

\begin{cases}x(t)=t\\y(t)=4t^2\end{cases}

with -3\le t\le1. Then

\displaystyle\int_Cxy\,\mathrm dx+(x+y)\,\mathrm dy

=\displaystyle\int_{-3}^14t^3\,\mathrm dt+(t+4t^2)(8t\,\mathrm dt)

=\displaystyle\int_{-3}^1(8t^2+36t^3)\,\mathrm dt=\boxed{-\frac{1936}3}

Mathieu is finding the x-intercepts of the function f(x) = x2 + 4x + 3. His work is shown below
Alex_Xolod [135]

Answer:

I can't see Mathieu's work but I will show the right steps and maybe you can find where Mathieu went wrong.

f(x)=x^2+4x+3

f(x)=(x+3)(x+1)       Since 3*1=3 and 3+1=4

The x-intercepts can be found by setting y to 0 and solving for x

(in other words replace that f(x) thing with 0 and solve for x)

0=(x+3)(x+1)

Now set both factors equal to 0

x+3=0       or      x+1=0

x   =-3                    x=-1

The x-intercepts are at (-3,0) and (-1,0)
