Answer:

x <= 0 or 1 = < x <= 5.

Step-by-step explanation:

First we find the critical points:

x(x - 1)(x - 5) = 0

gives x = 0, x = 1 and x = 5.

Construct a Table of values:

x < 0 x = 0 0< x < 1 1 =< x <= 5 x = 5

x <0 0 >0 <0 0

x - 1 <0 -1 >0 <0 0

x - 5 < 0 0 > 0 <0 0

x(x-1)(x-5) < 0 0 >0 <0 0

So the answers are x =< 0 or 1 =< x <= 5.

A forensic detective is called to the scene of a murder at 2 am. When she checks the temperature of the body, she sees that it i

Newton's Law of cooling is
$T(t)=T_{a}+(T_{0}-T_{a})e^{-0.1947t}$
where
T(t) = temperature of the body after t hours, 80 °F
$T_{a}$ = ambient temperature, 65 °F
$T_{0}$ = normal body temperature, assumed to be 98.6 °F

The elapsed time since death is obtained from
$65+(98.6-65)e^{-0.1947t|} = 80$
$33.6e^{-0.1957t}=15$
$-0.1947t=ln \frac{15}{33.6}$
$t= \frac{ln(15/33.6)}{-0.1947} =4.142$

4.142 hours before 2 am is 9:52 pm (the previous day) approximately.

Answer: 9:52 pm the previous day.

HELP PLSSS! IM IN A HURRY A savings account has a 3% interest rate.

zalisa [80]

Answer:

(a) Deposit ($) 100 400 50 300

Interest ($) 3 12 1.50 ___

(b) If you deposited 200, the interest would be $6, while if you deposited $150, the interest would be $4.50. So, you would have $1.50 more interest if you deposited $200 than if you deposited $150, or 33.33% more.

Step-by-step explanation:

(a)

100 × 0.03 = 3

0.03 × 100 is 0.03 moved 2 place values to the left, which would move the 3 to the ones place. This would make 3% of 100 equal to 3.

x × 0.03 = 12

3% of what is 12

Divide 12 by 3 to get 1% of the number, which is 4.

Now we can multiply this by 100 to get 400, which is the amount of money that was deposited.

50 × 0.03 = 1.50

3% of 100 is 3

100 ÷ 2 = 50

(3% of 100) ÷ 2 = 3% of 50

So, 3 ÷ 2 = 1.50

300 × 0.03 = 9

3% of 100 is 3

100 × 3 = 300

(3% of 100) × 3 = 3% of 300

So, 3 × 3 = 9

(b)

100 × 1.5 = 150

(3% of 100) × 1.5 = 3% of 150

So, 3 × 1.5 = 4.50

100 × 2 = 200

(3% of 100) × 2 = 3% of 200

So, 3 × 2 = 6

Now, to find how much more interest you would have if you deposited $200 than if you deposited $150, then you subtract 6 by 4.50 to get 1.50.

If you're looking for a percentage, you do 4.50 divided by 1.50 to get 3, which means that 1.50 is 1/3 of 4.50. So, the percentage of that is 33.33% with a line over the two 3's past the decimal point to indicate that the decimal repeats.

Sedaia [141]

2x + 6 >-6

subtract 6 from both sides

2x > -12

divide both sides by 2

x > -6
