The number of months required to pay off the loan will be 15.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that a student requests a loan for $1178.80. The monthly payment of the loan is $42.10. So far, the student has paid $547.30.

The number of the months will be calculated as,

N = ( 1178.8 - 547.30) / 42.10

N = 631.5 / 42.10

N = 15

Therefore, the number of months required to pay off the loan will be 15.

Using the given exponential function, it is found that:

a) The number of mosquitoes in the container after 5 days is of: 346.

b) The number of days until the container reaches the maximum capacity is of: 10 days.

The exponential function that models this problem is presented as follows:

P(t) = 24(4)^(0.385t).

Hence, after five days, the number of mosquitoes is of:

P(5) = 24(4)^(0.385 x 5) = 346 mosquitoes.

The number of days that it takes for the container to reach it's maximum capacity of 5000 is obtained solving the exponential function with logarithms as follows:

[tex]5000 = 24(4)^{0.385t}[/tex]

[tex](4)^{0.385t} = \frac{5000}{24}[/tex]

[tex](4)^{0.385t} = 208.3[/tex]

[tex]\log{(4)^{0.385t}} = \log{208.3}[/tex]

Applying the power property of logarithms, we have that:

[tex]0.385t\log{4} = \log{208.3}[/tex]

[tex]t = \frac{\log{208.3}}{0.385\log{4}}[/tex]

t = 10 days.

The simplified power functions are a) f(x) = [tex]\frac{-3}{2} x^-5[/tex] and b)g(x)=5[tex]x^\frac{1}{3}[/tex] .

What is power function ?

A function having a single term that is the sum of a real number, a coefficient, and a variable raised to a fixed real number is called a power function. Consider functions for area or volume as examples (a number that multiplies a variable raised to an exponent is known as a coefficient). A power function is a function where y = x n, where n is any real constant number. In reality, many of our parent functions, including linear and quadratic functions, are power functions.

Here ,

a) f(x) = [tex]\frac{-3}{2x^5}[/tex]

To write in the form of f(x)= [tex]kx^p[/tex]

=> f(x) = [tex]\frac{-3}{2}* \frac{1}{x^5}[/tex]

=> f(x) = [tex]\frac{-3}{2} x^-5[/tex]

b) g(x) = 5[tex]\sqrt[3]{x}[/tex]

Here we know that [tex]\sqrt[n]{a} = a^\frac{1}{n}[/tex] , then

=>g(x)=5[tex]x^\frac{1}{3}[/tex]

Hence the simplified power functions are a) f(x) = [tex]\frac{-3}{2} x^-5[/tex] and b)g(x)=5[tex]x^\frac{1}{3}[/tex] .

The definitions of translations are:

Horizontal translation:

For a general function f(x), a horizontal translation of N units is written as:

g(x) = f(x + N).

If N is positive, the shift is to the left.If N is negative, the shift is to the right.

Vertical translation:

For a general function f(x), a vertical translation of N units is written as:

g(x) = f(x) + N.

If N is positive, the shift is upwards.If N is negative, the shift is downwards.

The surface area of a sphere with radius r is given by4π[tex]r^{2}[/tex]

Given;

S = surface area at time t,  and r = radius at time t

radius of a spherical ball is increasing at a rate of 2 cm/min

radius: 6cm

Area of a sphere is A = 4π[tex]r^{2}[/tex]

Step 1: Differentiate area of a spherical ball

A = 4π[tex]r^{2}[/tex]

[tex]\frac{dA}{dt}[/tex] =[tex]\frac{d}{dt}[/tex](4π[tex]r^{2}[/tex])

b) The ascending order is -4 < -3.4 < -3 < -2 1/2 < π

c) The ascending order is -5/8 < 0 < 250% < 3.4

What is Ascending Order?

When numbers are arranged in ascending order, they are done so from least to largest. We must first compare the numbers before we may arrange them in any order. Compare first, then order. Numbers arranged in ascending order: Determine how many digits each number has.

Given data ,

A)

32 % , π , 2 1/2 , √9

32 % = 32 / 100

        = 0.32

π = 3.14

2 1/2 = 2.5

√9 = 3

So , arranging the numbers in ascending order we get ,

0.32 < 2.5 < 3 < 3.14

Hence , the ascending order is 32 % < 2 1/2 < √9 < π

B)

-3.4 , -4 , -3 , -2 1/2 , π  

Hence , the ascending order is -4 < -3.4 < -3 < -2 1/2 < π

C)    

250 % , 3.4 , -5/8 , 0

250 % = 2.5

-5/8 = -0.625

So , arranging the numbers in ascending order we get

Answer:

Step-by-step explanation:

The differentiation of the given function is 12[tex]x^3[/tex](5[tex]x^2[/tex] +2).

In the given question we have to differentiate the given function with respect to x.

The given function is f(x) = [tex]2x^4(5x^2+3)[/tex]

Before differentiating the function we first simplify the given expression.

To simplify the expression we multiply the 2x^4 to each term under the bracket.

Now the function;

f(x) = [tex]2x^4\cdot5x^2+3\cdot2x^4[/tex]

As we know that if the base is same en power get added.

f(x) = [tex]10x^{4+2}+6x^4[/tex]

f(x) = [tex]10x^{6}+6x^4[/tex]

Now differentiating the function with respect to x.

f'(x) = d/dx([tex]10x^{6}+6x^4[/tex])

f'(x) = 10d/dx([tex]x^6[/tex]) + 6d/dx([tex]x^4[/tex])

As we know that d/dx of x^n =nx^(n-1). So

f'(x) = 10∙6 [tex]x^5[/tex] + 6∙4 [tex]x^3[/tex]

f'(x) = 60[tex]x^5[/tex]+24[tex]x^3[/tex]

Now taking 12x^3 common

The 2.51 × 10⁻⁵ Watts/cm² sound intensity of the sound from the rocket engine has a decibel level of 114 dB

A decibel is a unit to measure the relative loudness of sound or to express the ratio electrical or acoustic power.

The intensity of the sound of the rocket engine = 2.51 × 10⁻⁵ Watts/cm²

Converting the unit of the sound intensity to Watts/m² gives;

1 cm² = 0.0001 m²

10,000 cm² = 1 m²

2.51 × 10⁻⁵ Watts/cm² = 10000 × 2.51 × 10⁻⁵ Watts/m² = 0.251 Watts/m²

The equation for the decibel from the power of sound is presented as follows;

[tex]\beta\ (dB)=10\cdot log_{10}\left(\dfrac{I}{I_0} \right)[/tex]

Where;

I₀ = 10⁻¹² W/m²

Which gives;

Step-by-step explanation:

If the endpoints of the line segment are (7,4) and (-9,-4), that means that the slope will be:

[tex]\frac{-4-4}{-9-7}[/tex] = [tex]\frac{-8}{-16}[/tex]=[tex]\frac{1}{2}[/tex]. For the perpendicular bisector to be perpendicular to the line, it must have a perpendicular slope, which will be the negative reciprocal of [tex]\frac{1}{2}[/tex], which is -[tex]2[/tex]. The perpendicular bisector must also go through the midpoint of the segment, which is (-1, 0) because -1 is the average of 7 and -9 and 0 is the average of 4 and -4.

Now we find the equation!

y=mx+b. Plug in -[tex]2[/tex]     as the "m", or slope:

y=-[tex]2[/tex]x+b

Now, plug in the point (-1, 0):
