The answer id 12 meters.divide -2x^2+20x+48 by 2 to get x alone and then umbrella
C = the square root of a^2 + b^2
AC = the sqrt of AB^2 + BC^2
AC = sqrt of 6^2 + 10^2
AC = 11.66
Volume of a cone is equal to pi*r^2*(h/3)
3.14*5^2*2/3 = 52.36 cubic cm.
Density = mass/volume
6 grams/ 52.36 cm^3= 0.1146
Round to 2 decimal places to get D.0.11 g/cm^3
Answer:
x = -5
Step-by-step explanation:
x - 15 = -20
+ 15 + 15
x = -5
Answer:
A
Step-by-step explanation:
Let x = Tan
dx = sec²d
sqrt(1 + 
) = sec
So I = Tan(theta) * sec(theta)
but Tan(theta) = sin(theta) / cos(theta) = sin(theta)*sec(theta)
So I = integral sin(theta)*sec^2(theta) d theta
Answer A
