real: 4 1/12

For the values running between (0, 0.177) ∩ (2.057, ∝) the speed of the particle moving with velocity v(t)=-t³+2t²+2^(-t) will be increasing.

Here we are given an equation of the velocity of the particle to be

v(t)=-t³+2t²+2^(-t)

Now taking the first derivative of v(t) and equating it to 0 we get

v'(t) = -3t² + 4t - 2^(-t)log2 = 0

Using Shreedharachara's method of solving quadratic equations we get the values of t to be

1.25635 and 0.17634

Now these 2 values are the points of inflexion, hence we will now take values a little lesser and greater than these 2 values to determine the increasing points of the function

Let's consider 0.16, 0.18, and 1.3

v'(0.16) = -0.0572

v'(0.18) = 0.0109

v'(1.3) = -0.152

Hence here we see that the values of the first derivative will be negative

The volume of fuel in the tank after 6 hours is 97.5 gallons.

To find the volume of fuel in the tank after 6 hours, we need to integrate the rate of change of the volume, given by V′(t)=4t/√(t^2+33), with respect to time from the initial time of t=√7 hours to t=6 hours.

The integral of V′(t) with respect to t is V(t)= 2/3 (t^3 + 33t) + C

We know that when t = √7 hours, the volume of fuel in the tank is 9.3 gallons. So we can use that information to find the value of the constant C.

9.3 = 2/3 (√7^3 + 33√7) + C

C = 9.3 - 2/3 (7^3/2 + 337^1/2)

C = 9.3 - 2/3 (343/2 + 337^1/2)

C = 9.3 - 2/3 (343/2 + 231)

C = 9.3 - 2/3 (574)

C = 9.3 - 382 = 5.5

Now we can substitute t = 6 into the equation for V(t) to find the volume of fuel in the tank after 6 hours.

V(6) = 2/3 (6^3 + 33*6) + 5.5

V(6) = 2/3 (216 + 198) + 5.5

V(6) = 2/3 (414) + 5.5

V(6) = 276/3 + 5.5

V(6) = 92 + 5.5 = 97.5

Answer:

Step-by-step explanation:

the answer if 7 yards because 21 feet divided by 3feet per yard you would get 7 yards

The percent decrease from June 2022 to August 2022 was 15%.

The percentage is defined as a ratio expressed as a fraction of 100.

During the month of June 2022, the average price per gallon of gas was $4.42.

During August of 2022, the average price per gallon of gas dropped to $3.75.

As per the question, the required solution would be as:

100 × (4.42 - 3.75) / 4.42

= 15.1583

Rounding to the nearest percent, we get

= 15%

Associative property of addition is applied in adding the polynomials to give

5x² + 5x + 9

According to the associative property of addition, altering how the addends are grouped has no effect on the sum.

This is applied in the addition of the given polynomial (3x + 4) + ((5x² - 1) + (2x + 6))

Addition of the polynomial

= (3x + 4) + ((5x² - 1) + (2x + 6))

= (3x + 4) + (5x² + 2x + 5)

= 5x² + 2x + 3x + 5 + 4

= 5x² + 5x + 9

altering the addends

= (5x² - 1) + ((3x + 4) + (2x + 6))

= (5x² - 1) + (3x + 4 + 2x + 6)

= 5x² - 1 + 5x + 10

The measure of angle x is  30°

Trigonometry is the branch of mathematics that deals with the relationships between the sides and angles of triangles, particularly right triangles. It is concerned with the measurement of angles and the calculation of sines, cosines, and tangents of those angles.

These ratios are known as trigonometric functions and they are used to relate the ratios of the sides of a right triangle to the angles opposite or adjacent to the right angle.

cos(x) = (√3)/2

x = cos⁻¹((√3)/2) = 30°

Answer:

a = 6 , b = 17

Step-by-step explanation:

using Pythagoras' identity.

the square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

using right triangle ABD , then

a² + 8² = 10²

a² + 64 = 100  ( subtract 64 from both sides )

a² = 36 ( take square root of both sides )

a = [tex]\sqrt{36}[/tex] = 6

using right triangle ABC

note that BC = a + 9 = 6 + 9 = 15

b² = 8² + 15² = 64 + 225 = 289 ( take square root of both sides )

b = [tex]\sqrt{289}[/tex] = 17

a) The y-intercept of the line is 25.66, which represents the predicted number of wins when yards allowed is 0.

b) The Seattle Sea hawks, the observed number of wins (10) is 4.12 less than the predicted number of wins based on the least-squares regression line.

c) It will increase the R-Sq and R-Sq(adj) and decrease the S.

The equation of the least-squares regression line is given by:

Number of wins = 25.66 - 0.003131 * (Yards_allowed)

This equation shows the relationship between the number of wins for a team (the dependent variable) and the number of yards allowed by the team (the independent variable).

The slope of the line is -0.003131, which means that for every 1 yard increase in yards allowed, the number of wins decreases by 0.003131. The y-intercept of the line is 25.66, which represents the predicted number of wins when yards allowed is 0.

b) To calculate the residual for the Seattle Seahawks, we can use the equation of the least-squares regression line and the data for the team:

Residual = Observed value - Predicted value

Residual = 10 - (25.66 - 0.003131 * 4668)

Residual = 10 - (25.66 - 14.12)

Residual = -4.12

This means that for the Seattle Seahawks, the observed number of wins (10) is 4.12 less than the predicted number of wins based on the least-squares regression line.

c) The point representing the Carolina Panthers (5167 yards allowed, 15 wins) has a positive effect on the equation of the least-squares regression line because it is above the line.

This means that the team performed better than expected based on the number of yards allowed. Since this point is an outlier, it will increase the R-Sq and R-Sq(adj) and decrease the S.

Answer: Murr's annual social security deduction is the amount of money he pays in social security taxes. Social security tax is 6.2% of Murr's annual salary. To find the annual social security deduction, we can multiply Murr's annual salary by the social security tax rate:

57,285.50 x 6.2% = 3,541.829

Murr's annual social security deduction is 3,541.829

Note that Medicare tax is 1.45% and it's calculated separately, if you want to calculate it you can use the same formula:

57,285.50 x 1.45% = 829.4078

So the total Social security and Medicare tax is 3,541.829 + 829.4078 = 4,371.2368

It's important to note that these are the federal Social Security and Medicare taxes, there might be additional state taxes or deductions that are not included.

Step-by-step explanation:

Multiples of 5 are numbers that are obtained by multiplying 5 by any whole number. So, to find the classmates numbered with multiples of 5, we can start by multiplying 5 by 1, then by 2, 3, and so on. The first few multiples of 5 are 5, 10, 15, 20, 25 and so on. Since the students are numbered from 1 to 24, only students whose numbers are less than or equal to 24 can be chosen.

So the possible classmates numbered with multiples of 5 that Jake can choose are 5,10,15,20.

In this case, the GCF is 5xa, as it can divide into both 5x²a and 5xa².

We can check this by dividing both terms with 5xa:

5x²a + 5xa² = (5xa)(x) + (5xa)(a) = 5xa (x + a)
