caffeine takes a certain amount of time to leave your system. if you drink 3 cups of coffee in the morning, the function that represents the amount of caffeine remaining in your body after drinking the coffee is given by g(t)=130(.8246)t where t is time in hours
A. How much caffeine remains in your system after day 1
B. How much caffeine remains in your system after 2 days?

Answers

Given:

The function g(t) represents the amount of caffeine remaining in your body after drinking the coffee.

[tex]g(t)=130(.8246)^t[/tex]

where t is time in hours.

To find:

The caffeine remains in your system after day 1.

The caffeine remains in your system after day 2.

Solution:

We know that,

1 day = 24 hours.

2 day = 48 hours.

The given function is

[tex]g(t)=130(.8246)^t[/tex]

Substitute t=24 in the given function to find the remaining caffeine in the system after day 1.

[tex]g(24)=130(.8246)^{24}[/tex]

[tex]g(24)=130(0.00977)[/tex]

[tex]g(24)=1.2701[/tex]

Therefore, the remains caffeine in your system after day 1 is about 1.2701.

Substitute t=48 in the given function to find the remaining caffeine in the system after day 1.

[tex]g(48)=130(.8246)^{48}[/tex]

[tex]g(48)=130(0.000095)[/tex]

[tex]g(48)=0.01235[/tex]

[tex]g(48)\approx 0.0124[/tex]

Therefore, the remains caffeine in your system after day 1 is about 0.0124.

Answer: for one day, it’s 0.0124

7) Choose the inequality that represents the statement.

The water level will be 10 feet or lower by tomorrow.

Answers

It’s the first one x equals less than or equal to ten

The water level will be 10 feet or lower by tomorrow, the correct inequality for this is x [tex]\leq \\[/tex] 10. Hence, the first option is the correct one.

What is inequality?

A connection in mathematics that compares two numbers or other mathematical expressions in an unequal way is known as an inequality. It is most frequently used to compare the sizes of two numbers on the number line. To indicate various sorts of inequalities, a variety of notations are used:

A less than symbol (a < b) indicates that an is less than b.A bigger value than b is indicated by the notation a > b.

These relationships are referred to be stringent inequalities since an is either strictly less than or strictly greater than b in these cases.

According to the question,

water will be equal to 10 feet or lower than 10 feet it cannot be greater than 10 feet.

Assume water is represented by x.

For water equal to 10 feet: x = 10 feet and,

For water lower than 10 feet: x < 10 feet.

So, we can write both like this: x [tex]\leq[/tex] 10

This concludes that the first option is correct.

What is the surface area of this right prism? Enter your answer in the box. m² Right triangular prism.

Answers

Hey there!

How to calculate Surface area

Step 1: Find the area of the top and the base triangles using the formula, Area of the two base triangles = 2 × (1/2 × base of the triangle × height of the triangle) which simplifies to 'base × height' (bh).

Step 2: Find the product of the length of the prism and the perimeter of the base triangle which will give the lateral surface area = (S1 + S2 + h) × l.

Step 3: Add all the areas together to get the total surface area of a right triangular prism in square units. This means, total surface area of a right triangular prism = (S1 + S2 + h) × l + bh

⇒ SA = (12 + 15 + 9) × 6 + (12)(9)

⇒ SA = (36)(6)+(108)

⇒ SA = 324 square units

Thus, the surface area of the right triangular prism is 324 square units.

Evaluate the function f(x)=5-3x when x=-1 and 3

Answers

Answer:

f(-1)=8

f(3)=-4

Step-by-step explanation:

when x equals -1 you substitute -1 for x in the equation which would look like 5-3(-1) which you would then multiply -3 by -1 and get 3 which 5+3 would equal 8 so f(-1) equals 8

When x equals 3 you substitute 3 for x in the equation which would look like 5-3(3) which you would then multiply -3 by 3 which would give you 5-9 which equals -4 so f(3) equals -4

On Tuesday, the temperature was 14°F. The next day it was 7° warmer. However, the wind chill temperature was 25° colder than the actual temperature. Victor says the windchill temperature is -18°F. Is he correct? Explain your reasoning.

The actual temperature was 14° + 7° =21°.
The windchill temperature was 21° - 25° = -4°.
Victor says the windchill temperature is -18°. This is incorrect because the windchill temperate is, in fact, -4°.

A straight line has 180 degrees. To find angle 1, subtract 43 from 180 which is 137.
Angle 2 is also 43 degrees and angle 3 would be 137 degrees.

Answer:

∠1 = 137

∠2 = 43

∠3 = 137

Step-by-step explanation:

∠2 and 43 are alternate interior angles.

Alternate interior angles are equal.

So,

∠2 = 43.

∠1 and ∠3 are also alternate interior angles,

So,

∠1 = ∠3

∠1 and 42 are linear pair angles.

Sum of linear pair angles is 180,

∠1 + 42 = 180

∠1 = 180 - 43

∠1 = 137

Since,

∠1 = ∠3

So,

∠3 = 137

Hence,

∠1 = 137

∠2 = 43

∠3 = 137

Note : -

Alternate interior angles and linear pair angles are properties of angles.

And are applicable when two lines intersect or more than two lines interest.
