Make u the subject of the formula D=ut + kt2

1 answer:

3 0

To make u the subject we proceed as follows:
D=ut+kt²
subtract kt² from both sides
D-kt²=ut+kt²-kt²

This will give us:
D-kt²=ut

next we divide both sides by t
(D-kt²)/t=ut/t

this will give us
u=(D-kt²)/t

simplifying the above we get:
u=D/t-kt

Answer: u=D/t-kt

If nothing is known about the shape of the distribution of a quantitative variable, what percentage of data fall within 2 standa

Nezavi [6.7K]

<span>At least 75% of the data will fall within 2 standard deviations of the mean. This is tricky problem. Usually when you're dealing with standard deviation, you have a bell curve, or something close to a bell curve and for such a data distribution, there will be approximately 95% of the data within 2 standard deviations of the mean. But if you don't know that you have a bell curve, you have to fall back to Chebyshevâ€™s Theorem, which states that at least 75% of the data points will fall within 2 standard deviations of the mean for any set of numbers.</span>

Which identity could be the missing step to verify the identity (cos theta)(csc theta)=cot theta

N76 [4]

(cosx)(cscx) = cotx
cscx = 1/sinx
(cosx)(1/sinx) = (cosx/sinx)
cosx/sinx = cotx

Basically, I noticed that cscx is equivalent to 1 divided by sinx, and then multiplied that fraction by cosx, which got me cosx/sinx. Your quotient identities will tell you that cosx/sinx = cotx

Answer:

a. $3,260.

Step-by-step explanation:

Tyler is planning to buy a new car. He intends to trade in his existing car, a 2002 Chrysler Sebring in good condition. Using the table below, we need to estimate about how much Tyler’s car is worth.

Given table is

Model/Year 2000 2001 2002 2003 2004

Pacifica $2,194 $2,288 $2,605 $2,690 $2,814

Concorde $1,842 $1,998 $2,180 $2,781 $2,925

Sebring $2,920 $3,075 $3,260 $3,551 $3,912

300M $2,770 $2,934 $3,095 $3,188 $3,676

Given choices are:

a. $3,260

b. $2,920

c. $2,605

d. $3,188

"2002 Chrysler Sebring" means look for the column of table which has year 2002. Then look for the row of the table which says "Sebring". Now we see that both rows and columns intersect at value $3,260.

Hence final answer is a. $3,260.
