Answer:
Using the Quadratic Formula
x=-b ± √b²-4ac/[2a]
x= -(-5) ± √5² - 4(1)(5)/(2)
x= 5 ± √25-20 /(2)
x= 5 ± √5 /(2)
x= 5 + √5/(2) and 5 - √5/(2)
Answer
B and C
Y = 8/cos60 = 16
x = sqr(16^2 + 8^2) = 8sqr(3) = 13.86 approx
Answer:
increasing straight line not passing through origin
Answer:
1 1/30 gallon
Step-by-step explanation:
Can A = 1/3 gallon
Can B = 1/5 gallon
Can C = 1/2 gallon
Total paint Neil has = Can A + Can B + Can C
= 1/3 + 1/5 + 1/2
The lowest common multiple of 3, 5 and 2 is 30
= (10+6+15) / 30
= 31/30
= 1 1/30 gallon of paint
Neil has a total of 1 1/30 gallon of paint
Answer:
31.5
Step-by-step explanation:
You have to break the shape up into a triangle and a rectangle
Area of a Triangle:
A=1/2(b)(h)
=1/2(7)(3)
=1/2(21)
=10.5
Area of Rectangle:
A= (b)(h)
=(7)(3)
=21
Area of Total Shape:
10.5 + 21
=31.5
