Answer:

x=1 y=-4

Step-by-step explanation:

Answer:

(1, - 4 )

Step-by-step explanation:

Given the 2 equations

y = - 5x + 1 → (1)

y = - x - 3 → (2)

Since both are expressed in terms of y, equate the right sides, that is

- x - 3 = - 5x + 1 ( add 5x to both sides )

4x - 3 = 1 ( add 3 to both sides )

4x = 4 ( divide both sides by 4 )

x = 1

Substitute x = 1 into either of the 2 equations and evaluate for y

Substituting into (2)

y = - 1 - 3 = - 4

Solution is (1, - 4 )

The volume of the pyramid is approximately 574,533.33 cubic meters.

To find the volume of a pyramid, you use the formula: V = (1/3) × base area × height, where B is the area of the base and h is the height of the pyramid.

Given that the side length of the square base is 140 m and the height is 91 m.

Since the base of the pyramid is a square with a side length of 140 m, we can find its area by multiplying the side lengths: B = 140m x 140m = 19,600 square meters.
By calculating this expression, you'll find the volume of the pyramid.

Now we can plug in the values for B and h into the formula: V = (1/3)(19,600 square meters)(91 meters) = 574,533.33 cubic meters.

The total number of different choices for the representative is 114

The number of choices for the representative to the university committee is the sum of the number of CS faculty members and the number of CS majors who are not faculty members.

Since no one can be both a faculty member and a student.

The number of choices for a faculty member is simply the number of members of the CS faculty, which is 9.

The number of choices for a CS major who is not a faculty member can be calculated by subtracting the number of CS faculty members from the total number of CS majors: 114 - 9 = 105.

Therefore, the total number of different choices for the representative is:

9 + 105 = 114

Step-by-step explanation:

1.  Use x to designate the number of hours worked.

Plumber 1 = 35(x) + 25

Plumber 2 = 40(x)

Now you need to find when these two equations are equal to each other.

35(x) + 25 = 40(x)

Solve for x.

25 = 40x - 35x

25 = 5x

5 = x

So when the service call equals 5 hours, both plumbers will charge the same amount of money.

2.  Use x to designate the number of months.

Center 1 = 30x

Center 2 = 22x + 80 initiation fee

Now you need to make the two equations equal to each other and solve for x.

30x = 22x + 80

30x - 22x = 80    or 8x = 80

x = 10 months

3.  Use x to designate the pounds of the package

Shipper 1 = 14 + 2x

Shipper 2 = 20 + 1.5x

Make the two equations equal to each other.

14 + 2x = 20 + 1.5x

2x - 1.5x = 20 - 14

0.5x = 6

x = 12 pounds

4. Deanna $15 using $0.75 per game.  This means she can play a total of 20 games before having $0.

Lise $13 using $0.50 per game.  This means she can play a total of 26 games before having $0.

So since both end up with $0, you can see that Deanna would play 20 games and Lise would play 26 games.

5.  Use x to designate the call time length.

Hotel 1 = 1 + 0.80x

Hotel 2 = 2 + 0.75x

Make both equations equal to each other.

1 + 0.8x = 2 + 0.75x

0.8x - 0.75x = 2 - 1

0.05x = 1

x = 20

6.  Use x to designate semesters.

Duke = 22 + 6x

Kila = 4 + 12x

22 + 6x = 4 + 12x

22 - 4 = 12x - 6x

The volume of the Solid -

V = ∫[-2,2] 4x^2(2x^2 - 1)(12x^2 - 1) dx

What is volume?

Volume is a measure of the amount of three-dimensional space occupied by an object or a region. It quantifies the extent or size of a solid object or a container. In simpler terms, volume is a measure of how much space an object takes up.

What is integral?

In mathematics, an integral is a fundamental concept in calculus that allows us to compute the total accumulation of a quantity over a given interval. It is used to find the area under a curve, the length of a curve, the volume of a solid, and many other applications.

To find the volume of the solid enclosed by the paraboloid z = 3x^2(y - 2)^2 and the planes z = 1, x = -2, x = 2, y = 0, and y = 2, we need to set up a triple integral over the given region.

The limits of integration for x, y, and z are as follows:

x: -2 to 2

y: 0 to 2

z: 1 to 3x^2(y - 2)^2

The volume V can be calculated as follows:

V = ∫∫∫R dz dy dx

where R represents the region defined by the given planes.

V = ∫∫∫R 3x^2(y - 2)^2 dz dy dx

To evaluate this triple integral, we integrate with respect to z first, then y, and finally x, using the given limits of integration:

V = ∫[-2,2] ∫[0,2] ∫[1,3x^2(y-2)^2] 3x^2(y - 2)^2 dz dy dx

Performing the integration:

V = ∫[-2,2] ∫[0,2] [3x^2(y - 2)^2z]∣[1,3x^2(y-2)^2] dy dx

V = ∫[-2,2] ∫[0,2] 3x^2(y - 2)^2[3x^2(y-2)^2 - 1] dy dx

V = ∫[-2,2] [x^2(y - 2)^2(3x^2(y-2)^2 - 1)]∣[0,2] dx

V = ∫[-2,2] 4x^2(2x^2 - 1)(12x^2 - 1) dx

Evaluate this integral using appropriate techniques or numerical methods, such as numerical integration or computer software, to find the volume of the solid enclosed by the paraboloid and the given planes.

∫3e^x dx = 3∫e^x dx = 3e^x + C₁

∫4x^5 dx = 4∫x^5 dx = 4 * (1/6)x^6 + C₂ = (2/3)x^6 + C₂

∫-x^3/4 dx = (-1/4)∫x^3 dx = (-1/4) * (1/4)x^4 + C₃ = (-1/16)x^4 + C₃

∫1 dx = x + C₄

∫(3e^x + 4x^5 - x^3/4 + 1)dx = 3e^x + (2/3)x^6 - (1/16)x^4 + x + C

Therefore, the indefinite integral of (3e^x + 4x^5 - x^3/4 + 1)dx is:

∫(3e^x + 4x^5 - x^3/4 + 1)dx = 3e^x + (2/3)x^6 - (1/16)x^4 + x + C

In this scenario, Kathy and Stan engage in a race, with Kathy starting 1.00 second after Stan. Stan maintains a constant acceleration of 3.8 m/s^2, while Kathy accelerates at a rate of 4.49 m/s^2. We need to determine the time at which Kathy overtakes Stan, the distance she travels before catching him, and the speeds of both cars at the moment Kathy overtakes Stan.

A) Kathy will overtake Stan when her displacement equals Stan's displacement. To calculate the time at which this occurs, we can use the equation:

s = ut + (1/2)at^2,

where s represents the displacement, u represents the initial velocity, a represents the acceleration, and t represents time. Rearranging the equation to solve for t:

t = √((2s)/a),

we find that Kathy overtakes Stan after approximately 7.26 seconds.

B) To determine the distance Kathy travels before catching Stan, we can use the equation:

s = ut + (1/2)at^2.

Substituting the values for Kathy's acceleration and the time calculated in part A, we find that Kathy covers a distance of approximately 98.24 meters.

C) At the instant Kathy overtakes Stan, their speeds will be equal. We can calculate their speeds using the equation:

v = u + at,

where v represents the final velocity, u represents the initial velocity, a represents the acceleration, and t represents time. Substituting the values for Kathy's acceleration and the time calculated in part A, we find that Kathy's speed at the moment she overtakes Stan is approximately 32.49 m/s. Since Kathy started 1.00 second after Stan, Stan's speed at that instant would be his initial speed plus the product of his acceleration and the time difference, resulting in approximately 25.8 m/s.

To find the capuchin monkey's weight with the same standardized weight as the lowland gorilla, we need to first calculate the z-score of the gorilla's weight.

The z-score represents how many standard deviations a data point is away from the mean.

For the gorilla with a weight of 345 pounds, the z-score can be calculated as follows: Z-score = (Weight - Mean) / Standard Deviation
Z-score = (345 - 275) / 40 = 70 / 40 = 1.75.

So a gorilla weighing 345 pounds has a standardized weight of 1.75 standard deviations above the mean. Now we need to find out how much a capuchin monkey would have to weigh to have the same standardized weight.

We can use the same formula and solve for x: z = (x - mean) / standard deviation .

1.75 = (x - 6) / 1.1
1.925 = x - 6
x = 7.925

So a capuchin monkey would have to weigh approximately 7.925 pounds to have the same standardized weight as a gorilla weighing 345 pounds. It's important to note that standardized weights are not the same as actual weights.

They are simply a way to compare values from different distributions on a common scale.

Now that we have the z-score, we can use it to find the capuchin monkey's weight with the same standardized weight: Weight = Mean + (Z-score × Standard Deviation), Weight = 6 + (1.75 × 1.1) = 6 + 1.925 = 7.925.

Therefore, a capuchin monkey would have to weigh approximately 7.93 pounds to have the same standardized weight as the lowland gorilla.
