Answer:
(5x -6)(5x +6) = 0
Step-by-step explanation:
Subtract 36 to put the equation in standard form. In this form, it looks like the difference of squares, so can be factored as such.
25x^2 -36 = 0
(5x)^2 -6^2 = 0
(5x -6)(5x +6) = 0
Step-by-step explanation:
The air plane is rising so the change in elevation is +1000 feet. The temp dropped and is -20 degrees fahrenheit.
1 degree per 50 ft
For every 1,000 feet that it climbs, the outside temperature drops 20 ... What is the rate of temperature change in degrees Fahrenheit per foot.
Hope I helped
Answer:
A
Step-by-step explanation:
If y = 0.5 x 3^x I will use any 2 points from the table to replace x and y.
Let's use (2 , 4.5) and (3 , 13.5).
0.5 x 3^2 = 0.5 x 9 = 4.5
x = 2 y = 4.5
0.5 x 3^3 = 0.5 x 27 = 13.5
x = 3 y = 13.5
The zeros of the function would be x=4.02 and x=0.98. Found using the quadratic formula.
