Answer:

[tex]z=\frac{s}{h-4c^4}[/tex]

Step-by-step explanation:

Switch the subject

[tex]s=zh-4zc^4\\zh-4zc^4=s[/tex]

Factor

[tex]zh-4zc^4\\=z\left(h-4c^4\right)\\z\left(h-4c^4\right)=s[/tex]

Divide: remember that h - 4c^4 is not equal to zero

[tex]\frac{z\left(h-4c^4\right)}{h-4c^4}=\frac{s}{h-4c^4}[/tex]

Simplify your solution where z is the redefined subject

[tex]z=\frac{s}{h-4c^4}[/tex]

Step-by-step explanation:

s=zh-4zc^4

we will factorise

s=z(h-4c^4)

we will divide both sides by (h-4c^4)

s/(h-4c^4)=z

z=s/(h-4c^4)

Answer: (262 - 70) ÷ 24

Step-by-step explanation:

The length of the longest altitude of the triangle is 24 √5 cm.

The sides of the triangle that are given are:

35 cm, 54 cm and 61 cm

We need to find the longest altitude of the triangle.

We know that:

s = ( a + b + c ) / 2

s = ( 35 + 54 + 61 ) / 2

s = 150 / 2

s = 75

s - a = 75 - 35

s - a = 40

s - b = 75 - 54

s - b = 21

s - c = 75 - 61

s - c = 14

Area, A = √ s (s − a)(s − b)(s − c)

A = √ 75 (40) (21) (14)

A = 420 √ 5 cm²

Now, area is also equal to:

Area = 1 / 2 × b × h

420 √5 = 1 / 2 × 35 × h

h = 420 √ 5 × 2 ÷ 35

h = 24 √5 cm

Therefore, the length of the longest altitude of the triangle is 24 √5 cm.

Using the law of sines, the length of side x, to 1 decimal place, is: 10.8 cm.

The law of sines states that:

Sin A/a = sin B/b = sin C/c.

Let:

Measure of angle A = 81°

a = x = ?

Measure of angle B = 40°

b = 7 cm

Plug in the values into Sin A/a = sin B/b to find the value of x

Sin 81/x = sin 40/7

Cross multiply

(x)(sin 40) = (sin 81)(7)

Divide both sides by sin 40

(x)(sin 40)/sin 40 = (sin 81 × 7)/sin 40

x = (sin 81 × 7)/sin 40

x = 10.8 cm (to 1 decimal place)

Therefore, using the law of sines, the length of side x, to 1 decimal place, is: 10.8 cm.

Answer:

Find K between M(1, -3) and N(4, 6) such that the

ratio of MK to KN is 1:2.

Step-by-step explanation:

Find K between M(1, -3) and N(4, 6) such that the

ratio of MK to KN is 1:2.

The coordinates of point K are (2, 0).

Given that there are three points M, K and N, such that M = (1, -3) and N = (4, 6) and the ratio of MK to KN is 1:2.

We need to find the coordinates of point K.

To find point K between M(1, -3) and N(4, 6) such that the ratio of MK to KN is 1:2, we can use the concept of section formula.

Let's assume the coordinates of point K are (x, y).

The section formula states that if a point K divides a line segment MN in the ratio m:n, then the coordinates of K are given by:

x = (n·x₁ + m·x₂) / (m + n)

y = (n·y₁ + m·y₂) / (m + n)

where (x₁, y₁) are the coordinates of point M and (x₂, y₂) are the coordinates of point N.

In this case, the ratio of MK to KN is 1:2, so m = 1 and n = 2.

Substituting the coordinates of M(1, -3) and N(4, 6) into the formula:

x = (2·1 + 1·4) / (1 + 2)

= (2 + 4) / 3

= 6 / 3 = 2

y = (2·(-3) + 1·6) / (1 + 2)

= (-6 + 6) / 3

= 0 / 3

= 0

So, the coordinates of point K are (2, 0).

The solution for the radical equation 2√x =√(x+1) is x=1/3

The phrase "algebraic expression" refers to any arrangement of terms that have undergone operations like addition, subtraction, multiplication, division, etc. (or variable expression).. Let's use the equation 5x + 7 as an example. Thus, 5x + 7 is an illustration of an algebraic expression.

Eliminate the radical on the both sides by squaring on both sides-

Both sides must be raised to the second power

(2√x)²=(√x+1)²

After squaring we get 4x=x+1

Solving the equation-

We get rearranged equation as 4x=x+1

3x=1    x=1/3

Check if the  solution is correct by putting it in original equation-putting x=1/3 in the equation 2√x =√(x+1)

2×√1/3=√1/3+1

4/3=4/3

Therefore, the solution for the radical equation 2√x =√(x+1) is x=1/3.

The logarithmic form of 8 = (1/2)⁻³ is given by log₍₁/₂₎(8) = -3.

The logarithm is exponentiation's opposite function in mathematics. This means that the logarithm of a fixed number, base b, represents the exponent to which that fixed number must be raised in order to create a particular number x.. The logarithm counts the number of times the same factor appears during repeated multiplication in the simplest scenario.

The given exponential form of the equation is 8 = (1/2)⁻³

To transform this exponential form into logarithmic form, we are requested.

Consider the given exponential form: 8 = (1/2)⁻³

Taking logarithm on both sides with the base as (1/2), we get,⇒ log₍₁/₂₎(8) = log₍₁/₂₎(1/2)⁻³

Now using the logarithmic rule logₐ(aⁿ) = n × logₐ(a) in the RHS of the above equation, we get

⇒ log₍₁/₂₎(8) = (-3) × log₍₁/₂₎(1/2)

⇒ log₍₁/₂₎(8) = (-3) × 1                  

(Since logₐ(a) = 1, for a &gt; 0)

⇒ log₍₁/₂₎(8) = -3

Therefore, the logarithmic form of 8 = (1/2)⁻³ is given by log₍₁/₂₎(8) = -3.

When choosing a loan, the best scenario is lower APR, shorter loan, and extra principal payments.

A loan is a type of debt that a person or other entity incurs. The lender advances the borrower a certain amount of money, typically on behalf of a business, financial institution, or government. The borrower accepts a specific set of terms in return, which may include any financial costs, interest, a repayment schedule, and other requirements.

APR represents the total yearly cost of a loan to the borrower, including all fees. The APR is stated as a percentage, just like an interest rate. It does, however, contain other costs or fees such as mortgage insurance, the majority of closing costs, discount points, and loan origination fees, unlike an interest rate. It should be noted that the APR simply means the annual percentage rate which is the interest that's generated on the amount borrowed.

Therefore, it should be noted that when choosing a loan, the best scenario is a lower APR, shorter loan, and extra principal payments

This is important in order to reduce the value that the person will pay and make it easier to return the loan.
