Answer: [tex]A(t) = 2,675(1.003)^{120}[/tex]

[tex]A(t) = 4,170(1.04)[/tex]

[tex]A(t) = 5,750(1.0024)^{20}[/tex]

Step-by-step explanation:

The exponential growth equation is given by :-

[tex]y=Ab^x[/tex] , where A = initial value , x= time period , b= growth factor.

The growth factor should be greater than 1.

From all the given options , the equations that are exponential :

[tex]A(t) = 2,675(1.003)^{120}[/tex]  , here b= 1.003

[tex]A(t) = 4,170(1.04)[/tex] , here b= 1.04

[tex]A(t) = 3,500(0.997)^{4t}[/tex]  , here b=  0.997

[tex]A(t) = 5,750(1.0024)^{20}[/tex]  , here b= 1.0024

[tex]A(t) = 1,500(0.998)^{127}[/tex]  , here b= 0.998

[tex]A(t) = 2,950(0.999)[/tex] , here b= 0.999

From the above exponential equations , only first  , second and fourth equation has b>1.

So , the models that could represent a compound interest account that is growing exponentially. are :

[tex]A(t) = 2,675(1.003)^{120}[/tex]

[tex]A(t) = 4,170(1.04)[/tex]

[tex]A(t) = 5,750(1.0024)^{20}[/tex]

Step-by-step explanation:

Im not entirely sure on this answer.

Your goal is to isolate x. So first subtract 3y on both sides resulting in 2xp=10-3y. Then u divide each side by 2p to get x by itself to get x=5p-3/2py.

Kyra will make 9 cans from the sheet of metal.

Solution:

Height of the can (h) = 5 in

Radius of the can (r) = 6 in

The can is in the shape of a cylinder.

Surface area of the cylinder = [tex]2 \pi r^{2}+2 \pi r h[/tex]

Surface area of the can = [tex]2 \times3.14 \times 6^{2}+2 \times 3.14 \times 6\times 5[/tex]

                                       [tex]$=226.08+ 188.57[/tex]

                                       [tex]=414.65[/tex]

Surface area of the can = 414. 65 in²

Area of sheet of metal = 3750 in²

To find how many cans able to make:

[tex]$\text { Number of cans} =\frac{\text { Area of sheet metal }}{\text { Surface area of the can }}[/tex]

                         [tex]$=\frac{3750}{414.65}[/tex]

                         = 9.04

Number of cans = 9

Hence Kyra will make 9 cans from the sheet of metal.

(f-g)(x) = [tex]x^{2}[/tex] + 2x + 8

Step-by-step explanation:

Step 1:

Formula for (f-g) (x) = f(x) - g(x)

Step 2:

Substitute values of f(x) and g(x) in the formula and solve

(f-g)(x) = (2x + 1) - ([tex]x^{2} -7[/tex])

(f-g)(x) = 2x + 1 - [tex]x^{2}[/tex] + 7

          = 2x + 8 [tex]- x^{2}[/tex]

          = [tex]x^{2}[/tex] + 2x + 8

The given algebraic expression 9a1/2b14c3/2 appears to be a kind of factorization where a, b, c are variables raised to different powers. Unless values for these variables are provided, this expression can't be simplified further.

The expression 9a1/2b14c3/2 is considered as a form of factorization in mathematics where a, b, c denote variables, and the numbers 1/2, 14, 3/2 are their respective exponents. In other words, it's a product of the variables 'a', 'b', and 'c' raised to their respective powers. For instance, 'a' is under a square root (as signified by the power of 1/2), 'b' is raised to the power of 14, and 'c' is also under a square root but cubed (a power of 3/2).

Consequently, this expression doesn't seem to have a simpler or equivalent expression because the terms 'a', 'b', and 'c' are likely representing different entities, hence they can't be combined or simplified further. However, should there be values for 'a', 'b', and 'c', it's simply substituted into the expression and calculated accordingly.

Answer:

[tex]\frac{120}{100}\times x=78[/tex] or [tex]12x=780[/tex]

Step-by-step explanation:

Given:

120% of x is equal to 78

We need to write an equation that shows the relationship of 120%, x, and 78

Solution:

We can write the 120% of x as:

⇒ 120% of x

Substitute [tex]\frac{120}{100}[/tex] in the place of 120%.

⇒ [tex]\frac{120}{100}\times x[/tex]

So, we write the equation as:

[tex]\frac{120}{100}\times x=78[/tex]

120 and 100 divided by 10.

[tex]\frac{12}{10}x=78[/tex]

Applying cross multiplication rule.

[tex]12x=780[/tex]

Therefore, equation shows the relationship of 120%, x, and 78.

[tex]\frac{120}{100}\times x=78[/tex] or [tex]12x=780[/tex]

Answer:

x = 40

Step-by-step explanation:

Since FG and HI are parallel and BC is a transversal, then

∠ GBE and ∠ GBE are same side interior angles and are supplementary, thus

3x + 20 + x = 180, that is

4x + 20 = 180 ( subtract 20 from both sides )

4x = 160 ( divide both sides by 4 )

x = 40

Answer:

(y = -8x - 6  and  y = 8x - 6) will have exactly one solution.

Step-by-step explanation:

1) Check number of solutions for A (using substitution)

y = -8x -6

y = -8x + 6

-8x - 6 = -8x + 6

+8x         +8x

0 - 6 = 0 + 6

-6 = 6 (since this is false, it would be no solution)

2) Check number of sultions for B (using substition)

y = -8x - 6

1/2y = -4x -3

y = -8x - 6 (Multiply both sides of second equation by 2 to cancel out fraction on left side)

-8x - 6 = -8x - 6

Since this is the same equation on both sides- when you cancel everything out it will be 0=0, meaning infinite solution

3) Check number of solutions for C (using substition)

y = -8x - 6

y = 8x - 6

-8x - 6 = 8x - 6

+8x   +6 = +8x +6

0 = 16x

x=0

The X value for the solution is 0, when we plug in this X value into one of the equations and solve for Y we will be able to get the Y coordinate

y = -8(0) - 6

y = -6

The solution for C will by (0,-6) which is one solution.

4) Check number of solutions for D (using substition)

y = -8x - 6

-y = 8x +6 --> y = -8x -6

muiltiply both sides of second equation by -1 to make the y positive

-8x - 6 = -8x - 6

Since this is the same equation on both sides- when you cancel everything out it will be 0=0, meaning infinite solution

Answer:

Step-by-step explanation:

The best way to rewrite the sentence is option D: "While he was driving on the highway, Paul saw a billboard advertising a music festival."

The original sentence is a bit awkward in its structure. Let's evaluate the options:

  This option is incorrect because it suggests that Paul was the one advertising the music festival while driving, which is not the intended meaning.

  This option is incorrect because it implies that the billboard itself was driving on the highway, which is illogical.

  This option maintains the original structure of the sentence, which is awkward and does not convey the intended meaning clearly.

  This option correctly places the modifier "advertising a music festival" next to "billboard," clarifying that it was the billboard, not Paul, advertising the music festival.

The probability of a customer choosing a medium size popcorn with butter is 1/6, or about 16.67%.

To find the probability that a customer chooses a medium size popcorn with butter from the Village Theater, we need to consider the total number of possible outcomes and the number of favorable outcomes. Given there are small, medium, and large sizes, and each can be buttered or plain, there are 3 sizes  imes 2 types (buttered or plain), which results in 6 total possible outcomes. The event of choosing a medium size with butter is just one of these possible configurations.

Probability of choosing a medium size with butter = Number of favorable outcomes / Total number of possible outcomes = 1 / 6

The chance is 16.67%, which is the decimal 1/6 expressed as a percentage.
