Answer:
Step-by-step explanation:
2x²+4x -16 = 2(x²+2x-8); factor 2
= 2(x+4)(x-2) ;factor the quadratic equation
4x²-16 = 4(x²-4) ; factor 4
=4(x²- 2²) ; rewrite 4 as 2²
= 4(x-2)(x+2); now use the difference of two squares a²-b²=(a-b)(a+b)
so now we have:
; simplify (x-2) from numerator and denominator
and 2/4 as 1/2
Answer:
A. 
Step-by-step explanation:
The question seems to be incomplete. However, we'll make the following assumption.
Pythagoras theorem states that:
Substitute values for Hypothenuse, Opposite and Adjacent.
This gives
or
From the list of given options.
A answers the question
Answer:
Below.
Step-by-step explanation:
To find the volume of the silo find the volum of the hemisphere with radius of 15 feet and add the volume of the cylinder with a radius of 15 feet and a height of (100 - 15) = 85 feet.
The total volume = 1/2 * 4/3 π (15)^3 + π (15)^2 * 85
= 67151.5 ft^3.
As you know, 4.78 is less than 5, so
.. yes, x=4.78 is a solution to x < 5
As you know, 6 = 6, but is not less than 6.
.. no, x=6 is not a solution to x < 6.
Answer: 1/3^4 or 1 over 3 fourths beacuse you need to just flip it to get the exponent to be positive. 3^-4 is basically 3^-4 over 1.
