A tumor is injected with 0.3 grams of Iodine-125, which has a decay rate of 1.15% per day. To the nearest day, how long will it take for half of the Iodine-125 to decay?

Answers

Answer:

The time required is 60.3 days.

Step-by-step explanation:

initial amount, No = 0.3 g

rate, r = 1.15 % per day = 0.0115 per day

final amount, N = 0.15 g

Let the time is t.

[tex]N = No e^{-rt}\\\\0.15 = 0.3 e^{-0.0115 t}\\\\0.5 =e^{-0.0115 t}\\\\- 0.6931 = - 0.0115 t \\\\t = 60.3 days[/tex]

Answer:

∠B= 102°, ∠Y= 32°

Step-by-step explanation:

The sum of the angles in a triangle is 180°.

∠A +∠B +∠C= 180° (∠ sum of triangle)

50° +∠B +28°= 180°

∠B +78°= 180°

∠B= 180° -78°

∠B= 102°

∠X= 180° -100° (adj. ∠s on a str. line)

∠X= 80°

∠X +∠Z +∠Y= 180° (∠ sum of traingle)

80° +68° +∠Y= 180°

∠Y +148°= 180°

∠Y= 180° -148°

∠Y= 32°

Alternatively,

∠Z +∠Y= ∠W (ext. ∠ of triangle)

68° +∠Y= 100°

∠Y= 100° -68°

∠Y= 32°

What is the percentage?

The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %.

Given that:-

Zelina scored 10% higher on her second quiz than on her first quiz. On her third quiz, Zelina scored 20% higher than on her second quiz.

From the given data we will see that:-

1 ) Zelina scored 10% higher on her second quiz than on her first quiz.

SQ = 1.10 FQ

2 ) On her third quiz, Zelina scored 20% higher than on her second quiz

TQ = 1.20SQ

From the above to expression solve for the first quiz:-

TQ = 1.20 x  1.10 FQ

TQ = 1.32FQ

Therefore Zelina scored 32% higher on the third quiz than on her first quiz.

Which expression is equivalent to (3x^2+4x-7)(x-2)

Answers

Answer:

Option C.

(3x² + 4x– 7)(x) + (3x² + 4x– 7)(–2)

Step-by-step explanation:

From the question given above, we obtained:

3x² + 4x– 7

x – 2

To know which option is correct, we shall obtained the product of the expression. The product of the expression can be obtained as follow:

(3x² + 4x– 7) (x – 2)

NOTE: (3x² + 4x– 7) will be multiplied by x and –2 as illustrated below:

x(3x² + 4x– 7) – 2(3x² + 4x– 7)

Rearrange

(3x² + 4x– 7)(x) + (3x² + 4x– 7)(–2)

Thus, Option C gives the correct answer to the question.

Don and Frank started from the same point and drove in opposite directions. Don's rate of travel was 50 miles per hour. Frank's rate of travel was 40 miles per hour. How many miles apart were they at the end of 2 hours?

Answers

9514 1404 393

Answer:

  180 miles

Step-by-step explanation:

Don drove (50 mi/h)×(2 h) = 100 mi.

Frank drove (40 mi/h)×(2 h) = 80 mi.

Since they drove in opposite directions, the total distance between them is

  100 mi +80 mi = 180 mi.

When a closed curve is parameterized by {x[t], y[t]}, then as you advance along the curve in the direction of the parameterization, which way do the tangent vectors {x'[t], y'[t]} at {x[t], y[t]} point; in the direction you are going, or in the direction opposite to the direction you are going?

Answers

Answer:

In the direction you are going,

Explanation:

We know that the tangent to  {x[t], y[t]} are  {x'[t], y'[t]}. Since  {x'[t], y'[t]} are tangents at  {x[t], y[t]}, we know that the tangent at a point is always parallel to the direction of the function at that point and in the direction of the function. So, the tangent vectors {x'[t], y'[t]} at {x[t], y[t]} point in my direction of motion as I move along the curve.

So, the tangent vectors {x'[t], y'[t]} at {x[t], y[t]} point in the direction you are going.

As a Mixed number: 7 1/4
As a fraction: 29/4
As a whole number: 7.25

You can pick either or

They just wanted you to add them all up 3 + 4 = 7 and then you have your 1/4 being 7 1/4

If you want it as a fraction you multiply and then add going clockwise. So we would multiply 4 by 7 = 28 plus 1 = 29 giving us 29/4.
Another example is 3 2/5. Multiply 5 by 3 which is 15 plus 2 will give us 17/5

To find the whole number you just divide 1 by 4 to get .25 so it would then be 7.25.
If it was 7 2/4 you would divide 2 by 4 and get 0.5 so it would be 7.5

A gambler is trying to determine whether or not to make a bet. If he bets and wins, he will profit $2000. If he bets and loses, he has to pay $300. The probability that he wins the bet is 15%. Find the gambler's expected value if he makes the bet.

Answers

Answer:

The gambler's expected value if he makes the bet is $45.

Step-by-step explanation:

Expected value:

15% probability of a profit of $2000.

100 - 15 = 85% probability of having to pay $300, that is, a loss of $300.

The expected value is each outcome multiplied by it's probability, so:

[tex]E = 0.15*2000 - 0.85*300 = 45[/tex]

The gambler's expected value if he makes the bet is $45.
