Answer:
If the equation is 2
+5x-3
then the factorized form would be (2x-1)(x+3)
Step-by-step explanation:
Volume = (4/3) * PI * radius^3
80 * PI = (4/3) * PI * radius^3
The 'PI's' cancel out leaving
80 = (4/3) * radius^3
radius^3 = 80/(4/3)
radius^3 = 60
radius = cube root (60)
In my opinion, the correct answer among the choices listed above is option B. A sphere made up of many circular cross sections. When you cut through a plane at any angle or side, you will see that the plane made will always be a circle.
Answer: e) 6
Step-by-step explanation:
Let x be mother + children = 18
Father's age = 38
Average age of the family = 14
38 + 18x /( x + 1 )= 14
Opening the bracket
38 + 18x = 14x + 14
Collecting like terms
24 = 4x
x = 6
no of children in the family is 6.
A = P(1+r/12)^12t, where A = amount after two years, P = Initial amount = $1000, r =apr = 4.2% = 0.042, t = period = 2 years
Then,
A = 1000 (1+0.042/12)^12*2 = $1087.47
