Answer:
d) 33.1 miles per gallon
Step-by-step explanation:
Mean = sum/ number
Mean= (48+25+35+34+33+37+32+34+23+30)/10 = 33.1
Answer: X=1.5
Step-by-step explanation:
Triangles ABC And DEF are not similar triangles.
Equations don't really have x intercepts, functions or curves do. They're also known as the zeros of the function. When we set a function equal to zero we get an equation to solve, and the zeros of the function become the solutions or roots of the equation.
If a quadratic equation only has one root, that's a repeated root corresponding to a discriminant of zero.
In this example our equation is something like
, or expanded

The discriminant
here is

H(t)=-16t²+500
0=-16t²+500
16t²=500
t²=31.25
t=5.9 seconds before the object hits the ground
