Amount $593.84 will be in the account after five years.

According to the question we have been given that the

 amount invested initially = $500

annual interest rate = 0.035

 Time = 5 years.

The formula for the future value is given as

         [tex]FV = a(1 + r)^{t}[/tex]        (1)

where , FV = future value

              a = amount invested initially

               r = annual interest rate

              t = time

putting the required values in equation (1) we get

       [tex]FV = 500 (1 + 0.035)^{5} \\FV = 500 ( 1.035)^{5}[/tex]

       FV = 500*1.188

       FV = $ 593.84

Thus, $593.84 will be the amount in the account after five years.

If the expression is log₃ 7(2 x-3)², then the expansion of the expression is [[tex]log_{3}[/tex] 7+ [tex]log_{3}[/tex] [tex](2x-3)^{2}[/tex]]

Given that the expression is log₃ 7(2 x-3)².

We are told to find the expansion of the expression.

Logarithmic function is basically the opposite of the exponential function and is denoted by log or ln.

It says that [tex]log_{a} b[/tex]= [tex]log_{x}b /log_{x}a[/tex].

The expression is log₃ 7(2 x-3)².

We know that log mn=log m +log n.

log₃ 7(2 x-3)²=[[tex]log_{3}[/tex] 7+ [tex]log_{3}[/tex] [tex](2x-3)^{2}[/tex]]

We know that log [tex]a^{b}[/tex]=log b/log a but we are not changing here,So,

log₃ 7(2 x-3)²=[[tex]log_{3}[/tex] 7+ [tex]log_{3}[/tex] [tex](2x-3)^{2}[/tex]]

Hence if the expression is log₃ 7(2 x-3)², then the expansion of the expression is [[tex]log_{3}[/tex] 7+ [tex]log_{3}[/tex] [tex](2x-3)^{2}[/tex]]

Answer:

y = -2

Step-by-step explanation:

Given equation:

[tex]3(-4y-5)=8y+25[/tex]

Distribute:

[tex]\implies 3 \cdot -4y - 3 \cdot 5=8y+25[/tex]

[tex]\implies -12y - 15=8y+25[/tex]

Add 15 to both sides:

[tex]\implies -12y - 15+15=8y+25+15[/tex]

[tex]\implies -12y =8y+40[/tex]

Subtract 8y from both sides:

[tex]\implies -12y-8y =8y+40-8y[/tex]

[tex]\implies -20y =40[/tex]

Divide both sides by -20:

[tex]\implies \dfrac{-20y}{-20} =\dfrac{40}{-20}[/tex]

[tex]\implies y =-2[/tex]

Now we have to,

→ solve for the required value of y.

Let's solve the problem,

→ 3(-4y - 5) = 8y + 25

→ -12y - 15 = 8y + 25

→ -12y - 8y = 25 + 15

→ -20y = 40

→ y = -40/20

→ [ y = -2 ]

Hence, the value of y is -2.

The inverse function returns the original value for which the output of a function was given.

The value of  f(x) = 10x - 10 is -110.

The inverse function returns the original value for which the output of a function was given. When it comes to functions, f and g are inverse, with f(g(x)) = g(f(x)) = x. A function that is made up of its inverse returns the original value.

An inverse in mathematics is a function that serves to "undo" another function. That is, if f(x) produces y, then putting y into the inverse of f yields x. Invertible functions are those that have an inverse, which is denoted by f1.

Lett the function be F(x) = 10x - 10

To differentiate with respect to X

F⁻¹(x) = 10

F( f⁻¹(x)) = F(10)

F( f⁻¹(x)) = -10x -10

Substitute the value of X = 10, then we get

F( f⁻¹(x)) = -10(10)-10

simplifying the above equation, we get

F( f⁻¹(x)) = -100-10

F( f⁻¹(x)) = -110

Therefore, the value of (f ⁰ f⁻¹)(d) = -110.

The surface area is the sum of the area of the surfaces. The surface area of the box is 360x^2 - 216x

The formula for calculating the surface area of a box is expressed according to the equation:

Surface area = 2(lw + wh +lh)

Given the following parameters

length = 6x

width = 12x - 9

height = 6x

Substitute

Surface area = 2(6x(12x-9) + (12x-9)(6x) +(6x)(6x))

Expand

Surface area = 2(72x^2-54x) + (72x^2-54x) + 36x^2)

Surface area = 2(180x^2-108x)

Surface area = 360x^2 - 216x

Answer: 8,938 [tex]\frac{8}{9}[/tex] or 8,938.8889 meters per second

Step-by-step explanation:

     To solve this problem, we will use a process called dimensional analysis (that you have probably done many times without realizing it).

     What is dimensional analysis? Let's say you know there are 12 inches in a foot, and you want to know how many inches are in 2 feet. 12 * 2 = 24 inches in a foot, that's dimensional analysis!

     Here is the process you would take to solve your problem:

➜ If we have the units [tex]\frac{hour}{hour}[/tex], they "cancel" out to become one. This way, we make sure we end up with the correct units, [tex]\frac{meters}{second}[/tex].

➜ We take units we know, such as 3,600 seconds in an hour, and multiply them by the original value until we end up with the measurement we want.

[tex]\displaystyle 20,000\; \frac{miles}{hour}*\frac{1 \;hour}{3,600\; seconds} *\frac{1,609\;meters}{1\;mile}=\frac{20,000*1*1,609\;meters}{3,600\;seconds} =\frac{32,180,000\;meters}{3,600\;seconds} = 8,938.89\; \frac{meters}{second}[/tex]

     In other words;

The value of the expression √75 + √125 is 5 (√3 + √5 ).

A number is a fundamental mathematical unit. For counting, measuring, and comparing quantities, we utilize numbers. A set of symbols, or numerals, used to represent numbers is known as a number system.

A square root is a factor of a number that yields the original number when multiplied by itself.

Consider the expression √75 + √125,

Let's assume x = √75 + √125

Now,

75 = 5 × 15 = 5 × 3 × 5

125 = 5 × 25 = 5 × 5 × 5

Therefore,

x = √75 + √125

x = √ [ 5 × 3 × 5] + √ [ 5 × 5 × 5 ]

x = 5√3 + 5√5

x = 5 × [ √3 + √5 ]

x = 5 × [ 1.73 + 2.24 ]

x = 5 × 3.97

x = 19.85

√75 + √125 = 19.85

Hence, the value of √75 + √125 is equal to 19.85.

Answer:

(0, - 9 )

Step-by-step explanation:

x = 2y + 18 → (1)

5x = - 3y - 27 → (2)

substitute x = 2y + 18 into (2)

5(2y + 18) = - 3y - 27

10y + 90 = - 3y - 27 ( add 3y to both sides )

13y + 90 = - 27 ( subtract 90 from both sides )

13y = - 117 ( divide both sides by 13 )

y = - 9

substitute y = - 9 into (1)

x = 2(- 9) + 18 = - 18 + 18 = 0

solution is (0, - 9 )

Step-by-step explanation:

We get the value of h(1) × g(1) as - 14 for the functions g (x) = x - 3 and h (x) = x² + 6.

We are given the two functions as:

g (x) = x - 3 and h (x) = x² + 6

Now, we will first find h (1)

h (1) = (1)² + 6

h(1) = 1 + 6

Add them, we get:

h (1) = 7

Now, we will find g (1):

g (1) = 1 - 3

g (1) = - 2

Now we will find the expression  h(1) × g(1):

h(1) × g(1) = 7 × ( - 2 )

h(1) × g(1) = - 14

Therefore, we get the value of h(1) × g(1) as - 14 for the functions g (x) = x - 3 and h (x) = x² + 6.

4x - 5 = 131 where x is the first number.

Step-by-step explanation:

Let the first number be x.

Seconder number = 2x + 7.

Third number = x - 12.

So, the equation is :-

x + 2x + 7 + x - 12 = 131

4x - 5 = 131

4x = 136

x = 34

First number = 34, second = 2(34) + 7 = 75 and third number = 34-12 = 22.
