We can translate the given problem into a table containing the data expressed as
x c(x) ($)2 274 10510 675
to find the total cost of producing 5 cases, we plot first the data and find the equation. The equation is c(x) = 7x2 - 3x + 5. when x is equal to 5, then c(x) is equal to $165
To create a line that is perpendicular to the one given, completely invert the slope.
y = -3/2x + 9
That is adjacent and huptonuse
soh cah toah
so that is cos
cos(x)=15/21
so tehrfor
cos⁻¹(15/21)=x
where cos⁻¹ means inverse not 1/cos
use your calculator to evaluate cos⁻¹(15/21) in degrees
it is about 44.4153 degres, rounded to 44 degrees
Answer:
Step-by-step explanation:
sin A= 21/29
cos A=20/29
tan A=21/20
sin B =20/29
Answer: x= 5 and y= -2 or (5,-2)
