Answer:
32.63 F
Step-by-step explanation:
The function:

represents sound travels s at feet per second, where t is the temperature at Fahrenheit degrees.
We know that sound traveled at a rate of 1121 ft/sec. To find the temperature we need to replace with s value and isolate t for the above function.






Answer:
14=0.5p+12
Step-by-step explanation:
i just did it lol
Turn F(x) into vertex form:
y=x^2+8x+6
y-6=x^2+8x
y-6+16=x^2+8x+16
y+10=(x+4)^2
Thus the vertex is (-4,-10)
This is a minimum because the parabola is up up, or is positive
Hello :
<span>h(x) = 6x² − 60x + 147= (x² -2(30)x+30²)-30²+147
</span>h(x) = (x-30)²-753 .....(vertex form)
<span>the axis of symmetry is the line of equation : x=30</span>
