Answer:

The value of average temperature during that period=\(58^{\circ}\)

Step-by-step explanation:

We are given that

Temperature at time t  is given by

\(T(t)=50+6t-\frac{1}{3}t^2\)

We have to find the average temperature during a certain  24-hour period.

We know that

Average value of function

\(f_{av}=\frac{1}{b-a}\int_{a}^{b}f(x)dx\)

Using the formula

Average temperature during the period

\(=\frac{1}{24-0}\int_{0}^{24}(50+6t-\frac{1}{3}t^2)dt\)

\(=\frac{1}{24}[50t+3t^2-\frac{1}{9}t^3]^{24}_{0}\)

\(=\frac{1}{24}(50\times 24+3(24)^2-\frac{1}{9}(24)^3)\)

\(=58^{\circ}\)

Hence, the value of average temperature during that period=\(58^{\circ}\)

Answer: I don’t understand

Step-by-step explanation:

The solution of the system of linear equation represented by the coordinates of the point of intersection of the two lines

Since we have two lines intersected at the point (-4, 1)

So the solution is (-4, 1)

To solve the above system of equation, let's use substitution method. Here are the steps:

1. Equate second equation to y = .

2. Use this value of "y" and plug it in to the first equation.

Then, solve for x.

It seems like both equations are just equal to each other. With this, the system has infinite number of solutions.

Answer:

We can evaluate this square root by prime factorizing the number first:

1471369 = 19 × 19 × 19 × 19 × 19

Taking the square root of each factor, we get:

√1471369 = √(19 × 19 × 19 × 19 × 19) = √19² × √19² × √19² × √19² × √19²

Simplifying, we get:

√1471369 = 19 × 19 × 19 = 6859

Therefore, the value of √1471369 is 6859.

After the double rotation, the vertices of the quadrilateral MNPQ are transformed to M'', N'', P'', and Q''. The shape of the quadrilateral may have changed, but the order of the vertices remains the same.

When a quadrilateral MNPQ is rotated counterclockwise at 90 degrees about the origin, each vertex undergoes a transformation.

The new positions of the vertices after this rotation can be denoted as M', N', P', and Q'. The order of the vertices remains the same.

Next, when the rotated quadrilateral M'N'P'Q' is further rotated counterclockwise at 270 degrees about the origin, each vertex undergoes another transformation.

The new positions of the vertices after this rotation can be denoted as M'', N'', P'', and Q''. Again, the order of the vertices remains the same.

It's important to note that a 270-degree counterclockwise rotation is equivalent to a 90-degree clockwise rotation.

The result of the double rotation is equivalent to a single clockwise rotation of 90 degrees.

Answer:

dz/dt = -(3x + 9y)/z

Step-by-step explanation:

x² + y² + z² = 9

2x dx/dt + 2y dy/dt + 2z dz/dt = 0

x dx/dt + y dy/dt + z dz/dt = 0

x * 3 + y * 9 + z dz/dt = 0

so

Answer:

The price of the new model will be $49,407.

Step-by-step explanation:

Percentages

The current model of a sports car costs $43,000. The new model is expected to cost 14.9% more than the current model.

The increase is:

14.9% of $43,000

=14.9/100 * $43,000

=$6,407

The cost of the new model is:

$43,000 + $6,407 = $49,407

The price of the new model will be $49,407.

Perimeter of the parallelogram = 210 in.

Area of parallelogram = 2,484 in.²

Perimeter of parallelogram = 2(a + b), where a and b are its sides.

Area of parallelogram = (b)(h), where h is its height and b is the length of one of its bases.

Given:

a = 51 in.

b = 54 in.

h = 46 in.

Perimeter of the parallelogram = 2(54 + 51) = 210 in.

Area of parallelogram = (b)(h) = (54)(46) = 2,484 in.²

Answer:

x = 51°, x = 91°

Step-by-step explanation:

8) To find ∠ C, we subtract 180° - 86°, since they are on the same line.

∠ C = 94°

We also know that all angles in a triangle must add up to 180°, so

∠ C + ∠ D + ∠ E = 180°

94° + 35° + ∠ E = 180°

∠ E = 180° - 94° - 35°

∠ E = 51°

x = 51°

9) We know that all angles in a triangle add up to 180°, so

∠ U + ∠ V + ∠ W = 180°

∠ U  + 62° + 29°= 180°

∠ U = 180° - 62° - 29°

∠ U = 89°

Since the x° angle is on the same line, we know that x° = 180° - 89°

x = 91°

Step-by-step explanation:

a. exponential function is\(y = 397,000*(1+0.03)^t\) b. Rounding to the nearest thousand, the population after 15 years will be 605,000

A mathematical function with the following formula is an exponential function:

\(f(x) = a^x\)

where x: input variable and an is a positive constant known as the base. As x increases or decreases, the value of the function either rises or falls exponentially. In other words, the function always increases or decreases at a rate that is proportionate to its current value.

a. The formula: can be used to create an exponential function that depicts the population after t years.

\(y = y 0 * (1 + r)^t\)

where t: number of years, r: yearly growth rate expressed as a decimal, and y 0 is the initial population.

The initial population in this instance is 397,000, and the yearly growth rate is 3%, or 0.03 in decimal form. The exponential function that depicts the population after t years is as follows:

\(y = 397,000 * (1 + 0.03)^t\)

b. We may change the exponential function we discovered in part a to include t = 15 to determine the population after 15 years:

\(y = 397,000 * (1 + 0.03)^(15)y = 605,464\)

After 15 years, the population will be roughly 605,000, to the nearest thousand.
