Answer:

12.56

Step-by-step explanation:

To get the length of the arc, we are going to use the formula for calculating the circumference of a semicircle.

Circumference of a  semi circle = πd/2

Given

Diameter d = 8

π = 3.14

Substitute;

C = 3.14(8)/2

C = 3.14 * 4

C = 12.56

Hence the the length of the arc is 12.56

Find the zeros of the function y=x^2-36​

Answers

Answer:

x=6,-6

Step-by-step explanation:

Whenever f(x) equals 0, the zeros of a function are indeed the values of x, and the calculation of zeros is as follows:

Finding the zeros in function:

The zeros of a function indicate that when f(x) = 0, x is the function's zero. Whenever the graph crosses over x = a, the function's zero is said to be a.

⇒ y=x²-36

Using formula:

⇒ a²-b²= (a+b)(a-b) ​

Solving equation to find zero:

⇒ y=x²-6²

⇒ y=(x-6)(x+6)

⇒ y=x±6

Therefore, the zeros of the function are "±6".

Grandma's age is 6 years less than 5 times Junior's age, j. If Grandma is 64 years old, which equation
can be used to find Junior's age?

Helppp

Answers

Answer:

junior is 6

Step-by-step explanation:

take 64 and divide by 5 you get 12 then take away the 6 years and you get juniors age which is 6

The equation used to find the age of Junior's age is 64 = 5J - 6 and the age of Junior will be 14 years old.

How to form an equation?

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Let's say Grandma's age is G while junior is J.

As per the given,

Grandma's age is 6 years less than 5 times Junior's age,

G = 5J - 6

64 = 5J - 6

J = 14

Hence "The equation used to find the age of Junior's age is 64 = 5J - 6 and the age of Junior will be 14 years old".
