Pythagoras theorem Please answer will mark BRAINELIST :)

Mathematics
1 answer:
Mumz [18]3 years ago
6 0

Answer:

Step-by-step explanation:

Since we are to show by Pythagoras that  the square will fit inside the circle without touching the edge of the circle , this means that we must find the value of the length of the diagonal of the square using Pythagoras.

For the square to fit in without touching the edge of the circle , this means that the diagonal of the square must be less than the diameter of the circle.

Length of the square is 5cm.

Recall Pythagoras theorem: it states that

the square on the hypotenuse of a right-angled triangle is equal in area to the sum of the squares on the other two sides

=  +

= 25 + 25

= 50

Take the square root of both sides , that is

D =

D =  X  , since 50 = 25 x 2

D = 5

D ≈ 7.07

which function has an inverse that is also a function? a. g(x) = 2x-3 b. k(x) = -9x2 c. f(x) |x+2| d. w(x) = -20
motikmotik

Answer:

A

Step-by-step explanation:

A function have the inverse only if it passes the horizontal line test ,

For the given options we need to look for the function which passes the horizontal line test

Option A is g(x)= 2x-3 which is a straight line with slope not equal to 0 so it passes the horizontal line test and hence it will have an inverse which is also a function.

Option B: we need to restrict the domain to get the inverse so the option B is not correct .

Option C : It also fails the horizontal line test .

Option D : Horizontal line so it also fails the horizontal line test .

Lesley works as a cars salesperson. She makes a monthly base salary of $1500. She also earns a 4% commission on all sales beyond
Troyanec [42]

Answer:

$1,740

Step-by-step explanation:

Setting up an equation to solve for Lesley's total salary would be the sum of her monthly base salary ($1,500) and the amount of her commission for any sales over $20,000:

Salary = $1,500 + (sales - $20,000)(0.04)

Since Lesley sold $26,000 in sales this month, we can calculate her total salary and commission:

Salary = $1500 + ($26,000-$20,000)(0.04) or $1500 + ($6000)(0.04)

Salary = $1500 + $240 = $1,740.00
