Answer:

200

Step-by-step explanation:

So say the dominoes' short side is x. Then the long side is 2x, so altogether there is 6x. So 6x=60, so x=10. So the area is 10*(10*2), which is 10*20 which is 200.

The parametric vector equations for the parabola y=x² from the origin to the point (3,9) is x = t and y = t² for the parameter range 0 <= t <= 3.

The required parametric vector equation for the parabola y=x² from the origin to the point (3,9) is given by the equations x = t and y = t². Here, t is the parameter. At t=3, these equations give us the coordinates x=3 and y=9, which corresponds to the point (3,9). Thus, these equations accurately represent the parabola y=x² from the origin to the point (3,9) for the parameter range 0 <= t <= 3.

In the parametric form, the path of a point on the parabola y=x² from the origin to point (3,9) is represented by a vector (t, t²) with t ranging from 0 to 3.

To find a vector parametric equation for the parabola y=x² from the origin to the point (3,9), we first need to understand that the parabola y = x² is not a vector in itself.

But, we can describe its trajectory through a parametric form using t as a parameter. For a given t, the parabola is represented by a vector (x(t), y(t)), where x(t) and y(t) are functions of t. For the specific parabola y = x², we can define the functions as x(t) = t and y(t) = t².

This means the vector at time t is given by (t, t²). From the origin (0,0) to the point (3,9), we now have a parameter t ranging from 0 to 3.

To calculate when the height of the projectile will be 1538 feet, use the kinematic equation and solve the quadratic equation for time.

To calculate when the height of the projectile will be 1538 feet, we can use the kinematic equation for free-falling objects. The equation is: h = [tex]h0 + v0*t - 16*t^2,[/tex] where h is the height above ground, h0 is the initial height (0 in this case), v0 is the initial velocity (320 ft/sec in this case), and t is the time.

Substituting the given values into the equation, we have: 1538 = 0 + 320*t - 16*t^2. Rearranging this equation, we get: [tex]16*t^2[/tex]- 320*t + 1538 = 0.

Now we can solve this quadratic equation for t by using the quadratic formula: t = (-b ± sqrt([tex]b^2[/tex] - 4ac)) / (2a), where a = 16, b = -320, and c = 1538. Plugging in these values, we can calculate the values of t.

Answer:

66,000 units

Step-by-step explanation:

Break-Even Sales (units) = Fixed Costs ÷ Unit Contribution Margin = $561,000 ÷ ($8 + $0.50) = 66,000 units

The break-even point in units after the decrease in variable costs is 66,000 units.

Given that the fixed costs are $561,000 and the original unit contribution margin is $8.00, we first calculate the original break-even point:

[tex]\[ \text{Original Break-even point in units} = \frac{561,000}{8} \][/tex]

[tex]\[ \text{Original Break-even point in units} = 70,125 \text{ units} \][/tex]

Now, since variable costs are decreased by $0.50 a unit, the new unit contribution margin becomes:

[tex]\[ \text{New Unit Contribution Margin} = 8 + 0.50 \][/tex]

[tex]\[ \text{New Unit Contribution Margin} = 8.50 \][/tex]

Using the new unit contribution margin, we calculate the new break-even point:

[tex]\[ \text{New Break-even point in units} = \frac{561,000}{8.50} \][/tex]

[tex]\[ \text{New Break-even point in units} = 66,000 \text{ units} \][/tex]

Therefore, the new break-even point in units, after the decrease in variable costs, is 66,000 units.

Let p(x) be a polynomial, and suppose that a is any real number. Prove that

lim x→a p(x) = p(a) .

Solution. Notice that

2(−1)4 − 3(−1)3 − 4(−1)2 − (−1) − 1 = 1 .

So x − (−1) must divide 2x^4 − 3x^3 − 4x^2 − x − 2. Do polynomial long division to get 2x^4 − 3x^3 − 4x^2 – x – 2 / (x − (−1)) = 2x^3 − 5x^2 + x – 2.

Let ε > 0. Set δ = min{ ε/40 , 1}. Let x be a real number such that 0 < |x−(−1)| < δ. Then |x + 1| < ε/40 . Also, |x + 1| < 1, so −2 < x < 0. In particular |x| < 2. So

|2x^3 − 5x^2 + x − 2| ≤ |2x^3 | + | − 5x^2 | + |x| + | − 2|

= 2|x|^3 + 5|x|^2 + |x| + 2

< 2(2)^3 + 5(2)^2 + (2) + 2

= 40

Thus, |2x^4 − 3x^3 − 4x^2 − x − 2| = |x + 1| · |2x^3 − 5x^2 + x − 2| < ε/40 · 40 = ε.

After solving the equations, it is found that there are 32 pennies in the jar.

To solve the problem of determining the number of pennies in the jar, first we establish two variables: let's denote P for the number of pennies and N for the number of nickels.

According to the problem, there are 56 coins in total, which gives us the equation P + N = 56. Also, we know that the total value of the coins is $1.52, and because each penny is worth 1 cent and each nickel is worth 5 cents, we have another equation, which is P + 5N = 152 (since there are 100 cents in a dollar).

Now we have a system of two equations to work with:

P + N = 56

P + 5N = 152

To find P, we can subtract the first equation from the second equation to eliminate P and solve for N:
0P + 4N = 96

N = 96 / 4

N = 24

Now that we know there are 24 nickels, we can find the number of pennies by substituting N back into the first equation:

P + 24 = 56

P = 56 - 24

P = 32

Therefore, there are 32 pennies in the jar.

Cory's percent error for his trip time prediction was 13.5% after rounding to the nearest tenth of a percent.

To calculate Cory's percent error for predicting his travel time to Baltimore from Washington D.C., we can use the formula for percent error:

Percent Error =[tex]|(Actual Value - Predicted Value) / Actual Value| \times 100%[/tex]

In this case, Cory's predicted time (Predicted Value) is 64 minutes, and the actual time taken (Actual Value) is 74 minutes. We can plug these values into the formula:

Percent Error = [tex]|(74 - 64) / 74| \times 100%[/tex]
Percent Error = [tex]|10 / 74| \times 100%[/tex]
Percent Error =[tex]0.1351 \times 100%[/tex]

Calculating further:

Percent Error = 13.51%

When rounded to the nearest tenth, Cory's percent error is 13.5%.

All of the expressions are equivalent except (b) -4 + y.

All the expressions involve adding -4 and - y in various orders, resulting in equivalent expressions due to the commutative property of addition.

However, the expression -4 + y  is different because it combines the positive y term with the negative 4, resulting in - 4 + y.

The other expressions either have y added to -4 ( -4 - y) or have -4 added to y (-y - 4, -y + (-4)).

While addition is commutative, changing the order of the terms can affect the overall expression when dealing with negative terms.

So, while mathematically equivalent, the form of -4 + y stands out due to its structure.

Final answer:

The tree in Carlos' backyard is 5 meters high, which is equivalent to 500 centimeters because there are 100 centimeters in a meter. Multiplying 5 meters by 100 gives us the height in centimeters.

Explanation:

To convert the height of the tree in Carlos' backyard from meters to centimeters, we need to know the conversion factor between these two units of measurement. There are 100 centimeters in a meter. Therefore, if the tree is 5 meters high, to find its height in centimeters, we multiply 5 meters by 100.

5 meters × 100 centimeters/meter = 500 centimeters

So, the tree is 500 centimeters tall when converted from meters. This is similar to the example given where Corey measures a distance of 8 meters between two trees and wants to convert that measurement to centimeters. In this concept, we are provided insight into converting with metric units of measurements which is crucial for accurately understanding dimensions in different units.

Final answer:

After calculations, it is determined that Manuel drove approximately 269 miles.

Explanation:

Manuel rented a truck which had a base fee of $14.95 and an additional charge of 87 cents per mile. To find the number of miles driven, we need to subtract the base fee from the total amount paid and then divide by the cost per mile.

First, subtract the base fee from the total cost:

Total amount paid = $248.98

Base fee = $14.95

Amount paid for miles = $248.98 - $14.95 = $234.03

Next, divide the amount paid for miles by the cost per mile:

Cost per mile = 87 cents = $0.87

Number of miles driven = $234.03 / $0.87 = 269 miles (approximately)

Therefore, Manuel drove approximately 269 miles with the rented truck.
