Alberto measures the length of a piece of wire to be 105 cm. The actual length of the wire was 120 cm. What was the percent erro

natali 33 [55]

Answer:

12.5%

Step-by-step explanation:

105 over 120 is the fraction that he got so you subtract 105 from 120 to get how much he missed. 120-105=15

He miscalculated by 15 cm out of the total of 120, 15/ 120

15/120=5/40=2.5/20 multiply the top and bottom by 5 to get the percentage out of 100. 2.5 times 5 =12.5, so he miscalculated by 12.5%

If parallelogram PQRS is dilated by a scale factor of 4 with a center of dilation at the origin, what is the area of parallelogr

victus00 [196]

The scale factor needs to be squared first before multiplying it to the area of parallelogram PQRS to find the area of dilation P'Q'R'S'. So in other words,

Area of P'Q'R'S' = 4² x Area of PQRS = 16 x Area of PQRS

Suppose the position of an object moving in a straight line is given by s (t )equals 4 t2+ 5 t+ 5. Find the instantaneous veloci

VLD [36.1K]

Answer:

$v(t) = 8t +5$

And that represent the instantaneous velocity at a given time t.

And then we just need to replace t =2 in order to find the instantaneous velocity and we got:

$v(t=2) = 8*2 + 5 = 16+5 = 21$

Step-by-step explanation:

For this case we have the position function s(t) given by:

$s(t) = 4t^2 + 5t+5$

And we can calculate the instanteneous velocity with the first derivate respect to the time, like this:

$v(t) = s'(t)= \frac{ds}{dt}$

And if we take the derivate we got:

$v(t) = 8t +5$

And that represent the instantaneous velocity at a given time t.

And then we just need to replace t =2 in order to find the instantaneous velocity and we got:

$v(t=2) = 8*2 + 5 = 16+5 = 21$
