The number of hours until the city is locked down is given as follows:

229 hours.

The function for this problem is defined as follows:

p(t) = 0.004t³ + 0.001t + 1.

For which the variables are given as follows:

The rate of change of the infection in 72 hours = 3 days is given by:

p'(3).

The derivative of the function is given as follows:

p'(t) = 0.012t² + 0.001.

After the instantaneous rate after 3 days is given as follows:

p'(3) = 0.012(3)² + 0.001

p'(3) = 0.109.

The city will lock down when p'(t) = 10 x p'(3) = 1.09 that is:

0.012t² + 0.001 = 1.09.

0.012t² + 0.001 - 1.09 = 0.

Hence the time in days is obtained as follows:

0.012t² = 1.089

t² = 1.089/0.012

t² = 90.75

[tex]t = \sqrt{90.75}[/tex]

t = 9.53 days.

Each day is composed by 24 hours, hence the time in hours is obtained as follows:

9.53 x 24 = 229 hours. (rounding to the nearest whole integer).

Answer:

Yes, the sides 7cm, 24cm and 25cm form a right angle triangle.

This is because the sides of a right angle triangle must follow the Pythagorean theorem, which states that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In this case, 7cm and 24cm are the two legs and 25cm is the hypotenuse.

Step-by-step explanation:

Yes, the coefficient of thermal expansion goes to zero at T approaches zero.The coefficient of thermal expansion is defined as the fractional change in volume per unit change in temperature.

The coefficient of thermal expansion is defined as the fractional change in volume per unit change in temperature. It is calculated by taking the derivative of volume with respect to temperature. Mathematically, it is expressed as β = (1/V) (dV/dT). As the temperature approaches zero, the change in volume (dV) will also approach zero, and thus the coefficient of thermal expansion (β) will approach zero as well.

The complete question : thermal expansion goes to zero at T approaches zero. By definition, the volume coefficient of thermal expansion is: beta = (1/V) (dV/dT). So, as T approaches zero, (dV/dT) approaches zero, and thus beta approaches zero.

The ratio A:D = 1:64

A ratio is the comparison of two amounts of the same unit which shows the amount of one present in the other.

Given that A:B = B:C = C:D if C:D is 1:4, we need to find A:D.

So, we proceed as follws

A:B = B:C = C:D

⇒ A/B = B/C = C/D = 1/4

So, we have that the equation

A/B = 1/4

This implies that

A = B/4

Also, we have that the equation
B/C = 1/4

This implies that

B = C/4

Finally, we have that

C/D = 1/4

This implies that

C = D/4

Since A = B/4, B = C/4 and C = D/4,

Substituting C into B, we have that

B = C/4

= (D/4)/4

B = D/16

Since A = B/4, substituting this B into A, we have that

A = B/4

= (D/16)/4

A = D/64

So, A/D = 1/64

⇒ A:D = 1:64

Step-by-step explanation: The correct answer is The probability that at least one of the alarm clocks will wake her up is 0.9604. Heather has a very important test to take in the morning. So she wants to be sure that she will wake up in time, so she sets two alarm clocks.

The probability the spinner landing on 5 is 0.125. The result is obtained by dividing the number of favorable outcomes by the number of events.

Probability is a numerical description of how possible an event to happen. Tha value of probability is between 0 to 1. Zero probability means something is impossible to happen. Probability 1 shows certainty.

Probability of an event can be expressed as

P(A) = n(A) / n(S)

Where

A spinner is divided into 8 equal sections numbered 1 to 8. Find the probability that the spinner lands on number 5!

From the information, we have:

P(A) = n(A) / n(S)

Step-by-step explanation:

The expression for pressure is P = k/V and pressure is 50 pounds per square inch.

Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other. Two categories can be used to categorize ratios. Part to whole ratio is one, and part to part ratio is the other. The part-to-part ratio shows the relationship between two separate entities or groupings.

Given pressure and volume are inversely proportional to each other

P ∝ 1/V

P = k/V

given when pressure p = 25 pounds per square inch

then volume V = 400 cubic inches

25 = k/400

k = 10,000

and when  V = 200 cubic inches

then P = k/V

P = 10000/200

P = 50 pounds per square inch

Hence pressure is 50 pounds per square inch.

You buy 3 tickets. You spent $225 to buy the tickets.

What is an equation?

A mathematical statement made up of two expressions joined by an equal sign is known as an equation. 3x - 5 = 16 is an example of an equation. We get the value of the variable x as x = 7 after solving this equation.

Given that there are two planes to buy tickets.

First plane offers $75 per ticket.

The other plan offers $180 plus $15 per ticket.

Assume that you buy x number of tickets.

According to the first plane, the total cost of x number of tickets is y = $75x.

According to the second plane, the total cost of x number of tickets is y = $180 + 15x

The system of equations is

y = $75x .....(i)

y = $180 + 15x  ....(ii)

Using the substitution method solve the equations.

The solution of the equations represents the total cost for the two options is the same.

Putting y = 75x in equation (ii)

75x = 180 + 15x

Subtract 15x from both sides:

75x - 15x = 180

60x = 180

Divide both sides by 60:

x = 3

Putting x = 3 in equation (i)

Answer: In order to solve this problem, you should use the Pythagorean theorem. Since FG is perpendicular to OP, and OP and OQ are radii of the same circle, then triangle OFG is a right triangle. Similarly, triangle ORS is also a right triangle. By using the Pythagorean theorem, you can find that:

OF = sqrt(OP^2 + FG^2) = sqrt(19^2 + 40^2) = sqrt(361 + 1600) = sqrt(1961)

A triangle with two sides that have the same length is said to be isosceles. It can be stated as having exactly two equal-length sides or at least two equal-length sides, with the latter definition containing the equilateral triangle as an exception.

A right triangle, also known as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or previously rectangled triangle, is a triangle with one right angle, or two perpendicular sides. The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.

A right triangle's three sides are related in Euclidean geometry by the Pythagorean theorem, also known as Pythagoras' theorem. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

The hypotenuse is 8 so the equal sides are x lets say.

The area of a triangle with the base 4.8 cm and height 3.6 cm is 8.64 cm².

Therefore the answer is 8.64 cm².

The area of a triangle can be calculated using the formula:

Area = (1/2) x base x height

In this case, the base of the triangle is 4.8 cm and the height is 3.6 cm. Plugging these values into the formula, we get:

Area = (1/2) x 4.8 x 3.6

Area = (1/2) x 17.28

Area = 8.64 cm²

So the area of the triangle is 8.64 square centimeterS.
