Answer:
9 more shots
Step-by-step explanation:
If the first golfer had a score of +6 and the second golfer had a score of -3, in order to know how many more shots the first golfer take, we will take the difference between both goals as shown;
= 6-(-3)
= 6+3
= 9
Hence the first golfer took 9 more shots than the second.
Completing the Square
2. Solve the equation by completing the square. Show your work.
x^2 – 30x = –125
Step 1: Add to both sides of the equation. (2 points)
Add 225 both sides of the equation
x^2 – 30x + 225 = –125
+ 225
x^2 - 30x + 225 = 100
Step 2: Factor the left side of the equation. Show your work. (2 points)
Hint: It is a perfect square trinomial.
x^2 - 30x + 225 = 100
Factor the left side of the equation:
(x - 15)^2 = 100
Step 3: Take the square root of both sides of the equation from Step 2. (1 point)
√(x - 15)^2 = √100
Step 4: Simplify the radical and solve for x. Show your work. (1 point)
x - 15 = + - 10
x - 15 = 10
x = 25
x - 15 = -10
x = 5
Solutions x = 25, 5
Answer:
Square root of 100.
Step-by-step explanation:
Step-by-step explanation:
We can write 10 as a fraction 10/1, therefore,
100 is a rational number.
Part A : A rational no. between 5.2 and 5.5 is 5.3.
It is rational because it can be expressed in the form
p/q where p and q are integers and q is not equal to 0, which is 53/10
Part B: A rational no. between 5.2 and 5.5 is 5.29150262213
An irrational number between 5.2 and 5.5 is 5.29150262213. It is irrational because there is no pattern that repeats and it cant be written as a fraction of two whole numbers.
As it has been given that
,
.
We need to find the value of the following:
(i)
, substituting the value of 'x' and 'y' in the expression, we get:


So, 
(ii)
, substituting the value of 'x' and 'y' in the expression, we get:


So, 
(iii)
, we need to substitute the value of 'x' and 'y' in the expression, for this, we can use distributive property of multiplication that says,

Using the distributive property of multiplication:


Now, we know that 
We get, 

Therefore,
=
.
(iv) We have,
, we need to substitute the value of 'x' and 'y' in the expression, we get:

Again, we can use distributive property of multiplication that says,

So,



since, 
we get,


Therefore,
