Answer:
$3400 after one year
$17400 after the 36 months
Step-by-step explanation:
3000+400*1=3400
3000+400*36=17400
After a year, $7,800 will have been spent on the car. The final cost of the car will be $16,800.
Explanation:i) To find out how much money will have been spent after a year, we need to substitute the value of M with 12 (since there are 12 months in a year) in the formula S = 3000 + 400M. Therefore, S = 3000 + 400 × 12 = $7,800.
ii) The final cost of the car can be found by substituting the value of M with 36 (since there are 36 months of payments) in the same formula. Therefore, S = 3000 + 400 ×36 = $16,800.

The temperature in Miami, Florida is 22 degrees warmer than three times the temperature in Bangor, Maine. The temperature in Miami is 82 degrees. Write an equation to determine the temperature in Bangor. 3x + 82 = 22 3x + 22 = 82 3x − 22 = 82 3x − 82 = 22
The equation to determine the temperature in Bangor is 3x + 22 = 82. Solving the equation gives the temperature in Bangor as 20 degrees.
Explanation:To write an equation to determine the temperature in Bangor, let's assume the temperature in Bangor is represented by the variable 'x'. The temperature in Miami is 22 degrees warmer than three times the temperature in Bangor. So, we can write the equation as follows:
3x + 22 = 82
Now, to find the temperature in Bangor, we need to solve for 'x'. We can do this by subtracting 22 from both sides:
3x = 82 - 22
3x = 60
Finally, divide both sides of the equation by 3 to solve for 'x':
x = 60 ÷ 3
x = 20
Therefore, the temperature in Bangor is 20 degrees.
Final answer:
The correct equation to find the temperature in Bangor, Maine, given the temperature in Miami, Florida, is 3x + 22 = 82. After solving, the temperature in Bangor is found to be 20 degrees Fahrenheit.
Explanation:
The temperature in Miami, Florida is given as 82 degrees Fahrenheit. According to the problem statement, this temperature is 22 degrees warmer than three times the temperature in Bangor, Maine. Thus, we can express this relationship algebraically as:
Miami temperature = 3 × Bangor temperature + 22
Substituting the known Miami temperature into the equation, we have:
82 = 3 × Bangor temperature + 22
To solve for the temperature in Bangor, we need to subtract 22 from both sides of the equation:
82 - 22 = 3 × Bangor temperature
60 = 3 × Bangor temperature
Finally, divide both sides by 3 to get the temperature in Bangor:
Bangor temperature = 60 / 3
Bangor temperature = 20 degrees Fahrenheit
Therefore, the correct equation to determine the temperature in Bangor is:
3x + 22 = 82
A circuit is supplied with 24 volts and its load offers a total resistance of 400 ohm. What’s the total circuit power?
Answer:
P = 1.44 Watts
Step-by-step explanation:
We know that the relation between voltage and current in a simple circuit with a resistor is
V = I.R
Where
V = the voltage of the source
I = current of the circuit
R = resistance
The power is defined as
P = V.I
Which is the same as
P = V.(V/R)
P = (24 v)^2 / (400 ohm)
P = 1.44 Watts
Write your answer without using negative exponents.
(w^5)^-7
Your answer would be [tex]\frac{1}{w^{35} }[/tex]
This is because (w^5)^-7 expands to give w^-35 because you multiply the exponents. When you have a negative exponent, this can also be written as a reciprocal, i.e. x^-2 = 1/x². This means that we can write w^-35 as 1/(w^35), which doesn't include any negative exponents.

The numerator and denominator of a fraction are in the ratio of 3 to 5. If the numerator and denominator are both increased by 2, the fraction is now equal to 2/3.
If n = the numerator and d = the denominator, which of the following systems of equations could be used to solve the problem?
5n = 3d and 3n + 6 = 2d + 4
5n = 3d and 4n + 4 = 3d + 6
3n = 5d and 3n + 6 = 2d + 4
Answer:
3n=5d and 3n = 5d and 3n + 6 = 2d + 4
Step-by-step explanation:
Answer: The correct option is
(A) [tex]5n=3d~~~\textup{and}~~~3n+6=2d+4.[/tex]
Step-by-step explanation: Given that the numerator and denominator of a fraction are in the ratio of 3 to 5. When the numerator and denominator are both increased by 2, the fraction is equal to \dfrac{2}{3}.

The factored form of polynomial P(x) shows only two of its roots. Assuming all of the
coefficients in the expanded form of P(x) are real, select each number that could be a
missing root of p(x)
Answer:
C and E
Step-by-step explanation:
Recall that according to the complex conjugate theorem, if P(x) is a polynomial function with real coefficients, and a+bi is an imaginary root of P(x), then its conjugate (i.e a-bi) must also be a root.
Here we see that 2 of the given roots are imaginary : i and 2+i
by the theorem given above, the conjugates of these must also be roots

Which polynomial has factors of 4x – 7 and x + 4?
answer: 4x² + 9x - 28.
multiply the factors together:
4x times x = 4x²
4x times 4 = 16x
-7 times x = -7x
-7 times 4 = 28
therefore, (4x-7) times (x+4) = 4x² + 16x -7x = 28
next, you must condense and simplify your answer:
16x -7x equals 9x
your final answer should be 4x² + 9x - 28.

use the distributive property to write an expression that is equivalent to 5(2x - 1)
Final answer:
To use the distributive property for the expression 5(2x - 1), multiply each term inside the parentheses by 5, resulting in the equivalent expression 10x - 5.
Explanation:
To use the distributive property to write an expression equivalent to 5(2x - 1), you simply multiply each term inside the parentheses by the factor outside, which is 5 in this case. So, you will multiply 5 by 2x and then 5 by -1.
Multiply 5 by 2x: 5 × 2x = 10x.
Multiply 5 by -1: 5 × -1 = -5.
Combine the two results to get the equivalent expression: 10x - 5.
Therefore, using the distributive property, the expression equivalent to 5(2x - 1) is 10x - 5.
Which relationship in the triangle must be true ?
Answer:
Choice B. sin(B)=cos(90-B)
Step-by-step explanation:
That cofunction identity is the one you looking for...choice B.
If you aren't convinced or don't know that identity, then maybe this will help:
90-B is actually the same thing as saying A for this right triangle since A+B=90.
So choice B basically says sin(B)=cos(A)
Well let's find both sin(B) and cos(A)
sin(B)=b/c
cos(A)=b/c
Those are the same ratios!
So they are equal!
Answer:
option B
Step-by-step explanation:
from the given options
a) sin (B) = sin (A)
b) sin (B ) = cos (90° - B)
cos (90° - B ) = Sin B
c) cos (B ) = sin(180° - B)
sin(180° - B) = sin (B)
d) cos (B) = cos(A)
so, we can clearly see from the above solution that option B is correct.
As 90° - B is in first quadrant and in first quadrant sign of cos dose not change and 90 is multiple of odd so 'cos' changes to 'sin'

The solution is:: the area cross sectional area of triangle form in the cone is 80ft²
What is area ?Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.
Given in the question,
radius of cone's base = 8ft
cone's base = base of triangle
height of cone = 10 ft
height of cone = height of triangle
Area of triangle
Area = 1/2(h)(b)
here h = height of triangle
b = base of triangle
A = 1/2(8)(10)
A = 40ft²
Since the section is 2 similar triangles back to back around the vertical center
so the area cross sectional area of triangle form in the cone is 2(40)ft² = 80ft²

then, the result is a real number, if and only if n is an odd number.
We analyze the options and find out that,the first option is where n is odd, because we have n=7.
Hence the only option that is equivalent to a real number is
[tex] { (- 6745)}^{ \frac{1}{7} } [/tex]
The correct choice is A.
Real numbers encompass all positive and negative integers, fractions, and decimals excluding imaginary numbers. In the given options, options B depicting a set of positive integers and C depicting a decimal number are examples of real numbers.
Explanation:In mathematics, a real number includes all positive and negative integers, fractions, and decimals without imaginary components. From the provided options, options B and C directly depict real numbers. Option B declares the values of x as a set of positive integers from 1 to 14.
While C represents a real number as a decimal 0.9417. To further understand, real numbers are embedded in our daily calculations, for instance, if you own 1 apple, spend $14, or measure a distance of 0.9417 km, these are all instances of real numbers.
