Explain how the distance formula can prove Pythagoras' Theorem. In your
explanation use the Pythagoras Theorem and how the distance formula can be used
with a right triangle when only given the hypotenuse.

Answers

Answer 1

Answer:

Given a triangle ABC, Pythagoras' Theorem shows that:

[tex]c^2=a^2+b^2[/tex]

Thus,

[tex]c = \sqrt{a^2+b^2}[/tex]

The distance formula, gives an equivalent expression based on two points at the end of the hypotenuse for a triangle.

[tex]d^2 = (x_{2} -x_{1})^2 + (y_{2} -y_{1})^2[/tex]

[tex]d = \sqrt{(x_{2}-x_{1})^2 + (y_{2} -y_{1})^2 }[/tex]

Therefore when given the hypotenuse with endpoints at

[tex](x_{1}, y_{1}) and {(x_{2}, y_{2})[/tex]

We know that the third point of the right triangle will be at

[tex](x_{2}, y_{1})[/tex]

and that the two side lengths will be defined by the absolute values of:

[tex](x_{2} - x_{1}) = a[/tex]

[tex](y_{2} - y_{1}) = b[/tex]

Lucas spends $83.42 in additional interest and charges on monthly payments as the result of a prior bankruptcy. if lucas been able to save this money for the year and then put it into a savings account earning 1.8% simple interest, how much money could he have in savings after 3 more years? a. $1,649.72 b. $1,055.10 c. $1,019.06 d. $1,001.04

Answers

The total amount Lusac have in his savings after 3 more years with 1.8% saving interest is $1055.10.

What is simple interest?

Simple interest is the amount charged on the principal amount with a fixed rate of interest for a time period. Simple interest calculated only on the principal amount.

The formula for the simple interest can be given as,

[tex]I=\dfrac{Prt}{100}[/tex]

Here, (I) is the interest amount earned on the principal amount of (P) with the rate of (r) in the time period of (t).

Lucas spends $83.42 in additional interest and charges on monthly payments as the result of a prior bankruptcy. The amount save in a year (12 months) is,

[tex]P=83.42\times12\\P=1001.04[/tex]

The interest earned on this principal amount with earning 1.8% simple interest, after 3 years is,

[tex]I=\dfrac{1001.04\times1.83}{100}\\I=54.06[/tex]

The total total amount in his bank account after 3 years is,

[tex]A=P+I\\A=1001.04+54.06\\A=1055.10[/tex]

Hence, the total amount Lusac have in his savings after 3 more years with 1.8% saving interest is $1055.10.

the mass of the metal
PLEASE HELP GIVING OUT BRAINLEST

Answers

Answer:

231.1 gm

Step-by-step explanation:

1040 J / .9 j/(gm-C)   / 5C = 231.1 gm

The mass of the metal is 231.111 gram.

What is specific heat?

The specific heat capacity of a substance is the heat capacity of a sample of the substance divided by its mass, also known as massic heat capacity.

The formula for heat is given by the formula,

Q = mC(ΔT)

Given the metal has a specific heat of 0.900 J/g °C requires 1,040 J of heat to raise the temperature (the change in temperature) by 5 °C. Therefore, we can write,

Q = mC(ΔT)

1,040 = m × 0.900 × 5

m = 1040/(0.900×5)

m = 231.111 g

Hence, the mass of the metal is 231.111 gram.

What is Inverse Function?

Inverse Function is a function that swaps domain and range.

What are domain and range?

Domain is the set of all x-values while Range is the set of all y-values, can be defined in coordinate point as (x,y).

Steps

If (x,y) is an original function then (y,x) will be an inverse function of original.

We are given the function g = {(a,1),(b,2),(2,3),(d,4)} - swap the domain and range.

Therefore, the inverse of function g is [tex]\displaystyle \large{g^{-1}}[/tex] = {(1,a),(2,b),(3,2),(4,d)}

A coconut falls from the top of a tree and reaches a velocity of 19.6 m/s when it hits the ground. it takes two seconds to reach the ground. what is the coconuts acceleration?

Answers

Using the velocity formula, it is found that the acceleration is of a = 9.8 m/s².

What is the velocity formula?

It is given by the initial velocity plus acceleration multiplied by time, that is:

v(t) = v0 + at.

In this problem, we have that v(0) = 0, t = 2, v(2) = 19.6, hence:

v(t) = v0 + at.

19.6 = 0 + 2a.

2a = 19.6.

a = 19.6/2.

a = 9.8 m/s².

The acceleration is of a = 9.8 m/s².
