Answer:
Dealership A is cheaper. Hope it helps.
Answer:
By comparing both the payments we can say that Dealer A is cheaper by $4.50.
Step-by-step explanation:
Dealership A: The car costs $30,000, and the loan has an annual interest rate of 4.8% for 5 years.
The EMI formula is :
[tex]\frac{p\times r\times(1+r)^{n} }{(1+r)^{n}-1 }[/tex]
Now, p = 30000
r = [tex]4.8/12/100=0.004[/tex]
n = [tex]5\times12=60[/tex]
Putting values in formula we get;
[tex]\frac{30000\times0.004\times(1+0.004)^{60} }{(1+0.004)^{60}-1 }[/tex]
=> [tex]\frac{30000\times0.004\times(1.004)^{60} }{(1.004)^{60}-1 }[/tex]
EMI is = $563.34
Dealership B: The car costs $29,800, and the loan has an annual interest rate of 5.4% for 5 years.
p = 29800
r = [tex]5.4/12/100=0.0045[/tex]
n = [tex]5\times12=60[/tex]
Putting values in formula we get;
[tex]\frac{29800\times0.0045\times(1+0.0045)^{60} }{(1+0.0045)^{60}-1 }[/tex]
=> [tex]\frac{29800\times0.0045\times(1.0045)^{60} }{(1.0045)^{60}-1 }[/tex]
EMI = $567.84
By comparing both the payments we can say that Dealer A is cheaper by $4.50.

The square of the sum of two consecutive positive even integers is 4048 more than the sum of the squares of these two numbers. Find the two numbers.
Answer:
44, 46
Step-by-step explanation:
The integers are both even, so if the smaller one is x, then the larger one is x+2.
Therefore:
((x) + (x+2))² = 4048 + (x)² + (x+2)²
(2x + 2)² = 4048 + x² + x² + 4x + 4
4x² + 8x + 4 = 2x² + 4x + 4052
2x² + 4x - 4048 = 0
x² + 2x - 2024 = 0
(x + 46) (x - 44) = 0
x = -4+, 44
Since x must be positive, x = 44. And x+2 = 46. So the numbers are 44 and 46.
Let's check:
(44 + 46)² = 8100
4048 + 44² + 46² = 8100
The volume of box A is 2/5 the volume of box b. What is the height of box A if it has a base area 32 square centimeters
The length of the edge of the bases is x = 4 and x=1.79.
What is the volume of the box?The volume of a rectangular box can be calculated if you know its three dimensions: width, length, and height.
The volume of a box with a square base and a height of 2 cm is 32cm for box A and the volume of a box with a square base and a height of 10cm is 32cm.

17. Which of the following is the correct formula for finding power in a DC circuit? A. P = I2R B. P = VR C. P = IR D. P = V2I
Answer:
Choice A. P = I² · R where
P is the power in the DC circuit,I is the current through the circuit, andR is the total resistance of the circuit.Step-by-step explanation:
Electrical power is the rate at which the electrical force does work. So what is electrical work? That's the work [tex]W[/tex] that the electrical force do when it moves charges [tex]Q[/tex] across a potential difference [tex]V[/tex]:
W = [tex]V\cdot Q[/tex].
The power is the rate at which the electrical force do the work:
[tex]\displaystyle P = \frac{W}{t} = V \cdot \frac{Q}{t}[/tex].
On the other hand, current [tex]I[/tex] is the charge through a cross-section of the circuit in unit time. By the definition of current:
[tex]\displaystyle\frac{Q}{t} = I[/tex].
[tex]\displaystyle P =V \cdot \frac{Q}{t} = V\cdot I[/tex].
Consider Ohm's Law:
[tex]V = I \cdot R[/tex].
Therefore
[tex]\displaystyle P = V\cdot I = (I \cdot R) \cdot I = I^{2}\cdot R[/tex].
Choice-A is one of several useful, correct formulas for electrical power. It's true in AC circuits as well as DC ones.

Answer:
Option B.
Step-by-step explanation:
∠1 and ∠3 are supplementary and ∠2 and ∠4 are supplementary.
Because they are exterior sides in opposite rays.
In other words ∠1 + ∠3 = 180° and ∠2 + ∠4 = 180°
and it is given that ∠1 ≅ ∠2
So ∠3 ≅ ∠4
Since Two angles supplementary to equal angles are equal will be the reason.
Option B is the correct option.

Answer:
[tex]A = 301.59\ cm^2[/tex] or [tex]A=96\pi\ cm^2[/tex]
Step-by-step explanation:
The lateral area of a cylinder is calculated by the following formula
[tex]A = 2\pi r * h.[/tex]
Where r is the radius of the right cylinder and h is the height
In this case we know that the diameter d of the cylinder is
[tex]d=2r\\\\r=\frac{d}{2}\\\\r=\frac{12}{2}\\\\r=6\ cm[/tex]
[tex]h=8\ cm[/tex]
Therefore the lateral area is:
[tex]A = 2\pi*6 * 8.[/tex]
[tex]A = 96\pi[/tex]
[tex]A = 301.59\ cm^2[/tex]
Answer:
The lateral area of a right cylinder = 96π cm²
Step-by-step explanation:
Points to remember
The lateral area of a right cylinder = 2πrh
Where r - Radius of cone and
h - Height of cone
To find the lateral surface area
Here diameter d = 12 cm
then radius r = d/2 = 12/2 = 6 cm
And h = 8 cm
Lateral surface area = 2πrh
= 2 * π *6 * 8 = 96π cm²
Therefore the lateral area of a right cylinder = 96π cm²

True or false: When it's argument is restricted to (0,2pi), the polar form of a complex number is *not unique*.
Answer:
The CORRECT answer is False
Step-by-step explanation:
I just took the test and got it correct!!
cos x + i sin x in the range 0 to 2pi will be unique so false.
What do you mean by complex number?Complex numbers exist the numbers that exist expressed in the form of a+ib where, a, and b are real numbers, and 'i' exists an imaginary number named “iota”. The value of i = (√-1).
The abbreviated polar form of a complex number exists z = rcis θ, where r = √(x2 + y2) and θ = tan-1 (y/x).
The range is the difference between the highest and lowest values in a set of numbers. To find it, subtract the lowest number in the distribution from the highest.
The range in statistics for a given data set is the difference between the highest and lowest values. For example, if the given data set is {2,5,8,10,3}, then the range will be 10 – 2 = 8. Thus, the range could also be defined as the difference between the highest observation and lowest observation.
Hence, cos x + i sin x in the range 0 to 2pi will be unique so false.

By applying the sum-product pattern, we have:
9x² + 15x - 12x - 20
By writing the common factor from the two pairs, we have:
(9x² + 15x) + (-12x - 20)
3x(3x + 5) - 4(3x + 5)
(3x + 5)(3x - 4)
Next, we would expand the expression (4x - 3y)²;
(4x - 3y)(4x - 3y)

A 254–foot tall radio tower is located partway between a building and a tree. The angle of elevation from the base of the building to the top of the tower is 36°, and the angle of elevation from the base of the tree to the top of the tower is 62°. What is the distance from the base of the building to the base of the tree (rounded to the nearest foot)?
Answer:
485 ft
Step-by-step explanation:
step 1
Find the distance from the base of the building to the base of the radio tower
Let
x -----> the distance from the base of the building to the base of the radio
we know that
tan(36°)=254/x
x=254/tan(36°)=349.60 ft
step 2
Find the distance from the base of the tree to the base of the radio tower
Let
x -----> the distance from the base of the tree to the base of the radio tower
we know that
tan(62°)=254/x
x=254/tan(62°)=135.05 ft
step 3
Find the distance from the base of the building to the base of the tree
Adds the distances
349.60 ft+135.05 ft=484.65 ft
Round to the nearest foot
484.65 ft=485 ft
The final distance is approximately 485 feet.
Calculating the Distance from the Building to the Tree
To determine the distance from the base of the building to the base of the tree given the angles of elevation to the top of the radio tower, we can use trigonometry.
Let the height of the radio tower be 254 feet. Assume the distance from the base of the building to the base of the tower is x feet, and the distance from the base of the tree to the base of the tower is y feet.
Step-by-Step Solution:
Using the angle of elevation from the building, 36°, we can write:
tan(36°) = 254 ÷ x
Solving for x: x = 254 / tan(36°)
Using the angle of elevation from the tree, 62°, we can write:
tan(62°) = 254 ÷ y
Solving for y: y = 254 / tan(62°)
Calculate the values:
tan(36°) ≈ 0.7265
x = 254 / 0.7265 ≈ 349.6 feet.
tan(62°) ≈ 1.8807
y = 254 ÷ 1.8807 ≈ 135.1 feet.
The total distance from the base of the building to the base of the tree is x + y:
Total distance = 349.6 + 135.1 ≈ 485 feet.
Thus, the distance from the base of the building to the base of the tree is approximately 485 feet.

Step-by-step explanation:
Let's call the width and height of the rectangle w and h.
w / h = 3 / 4
2w + 2h = 28
Solve the system of equations with substitution.
w = 3/4 h
2 (3/4 h) + 2h = 28
3/2 h + 2h = 28
7/2 h = 28
h = 8 cm
So the width is:
w = 3/4 (8)
w = 6 cm
So the area is:

Suppose y varies jointly as x and z. Find y when x = 5 and z = 16, if y = 136 when x = 5 and z = 8. Round your answer to the nearest hundredth, if necessary.
Answer:
The value of y when x = 5 and z = 16 is 272
Step-by-step explanation:
* Lets Talk about the direct variation
- y is varies jointly (directly) as x and z, that means there are direct
relation between y , x and z
- y increases if x increases or z increases
∴ y ∝ x × z
- To change this relation to equation we use a constant k
∴ y = k (x) (z), where k is the constant of variation
- To find the value of k we substitute the values of x , y and z in
the equation above
∵ y = 136 when x = 5 and z = 8
∴ 136 = k × 5 × 8
∴ 136 = 40 k ⇒ divide both sides by 40
∴ k = 3.4
- Substitute this value in the equation
∴ y = 3.4 (x) (z)
∵ x = 5 , z = 16
∴ y = 3.4 (5) (16) = 272
∴ The value of y when x = 5 and z = 16 is 272
Answer:
The correct answer is B.
Step-by-step explanation:
If y varies jointly as x and z, then we can write the join variation equation.
[tex]y=kxz[/tex], where 'k' is the constant of proportionality.
If y = 136 when x = 5 and z = 8,then
[tex]136=k(5)(8)[/tex],
[tex]\implies 136=40k[/tex]
[tex]\implies \frac{136}{40}=k[/tex]
[tex]\implies \frac{17}{5}=k[/tex].
The variation equation now becomes:
[tex]y=\frac{17}{5}xz[/tex]
when x = 5 and z = 16, then
[tex]y=\frac{17}{5}(5)(16)[/tex]
[tex]y=17(16)[/tex]
[tex]y=272[/tex]
The correct answer is B.
