Answer:
- (√30 - 1, 0)
- (-√30 - 1, 0)
Step-by-step explanation:
Making the equation of the parabola :
⇒ y = a(x - h)² + k
⇒ y = (x + 1)² - 17 - 13
⇒ y = (x + 1)² - 30
x-intercepts have y = 0 :
- 0 = (x + 1)² - 30
- (x + 1)² = 30
Taking the square root on each side :
- √(x + 1)² = √30
- x + 1 = ±√30
- x = ±√30 - 1
The x-intercepts are :
- (√30 - 1, 0)
- (-√30 - 1, 0)

Answer:
The percentage error of measurement is 5.63 %
Step-by-step explanation:
Given as :
The measure length of the fence = 150 feet
The actual length of the fence = 142 feet
Let the percentage error in measurement = x
So, x =
×100
Or, x =
×100
or, x =
×100
or, x = 5.63 %
Hence The percentage error of measurement is 5.63 % Answer
Step 1
Find the common denominator.
5/8 and 1/6---------> would be 2³*3----> 24
step 2
multiply (5/8) by (3/3) and (1/6) by (4/4)
5/8-----> 15/24
1/6-----> 4/24
step 3
find the numbers
4/24+15/24------> 19/24
4/24-15/24-------> -11/24
the answer isthe two numbers are19/24 and -11/24see the attached figure
