The function s(t, r)=70(t−90)(4−r) gives an ice cream shop's daily sales as a function of temperature t (in degrees°f) and rain r (in inches). find sr (80, 6) (include the appropriate units) and explain what it means.

The value of Sr (80, 6) is 1400 units.

The shop's daily sales when temperature is 80°F and rain is 6 inches.

Step-by-step explanation:

Given function that represents the daily sale,

S(T,r)=70(T−90)(4−r),

Where,

T = temperature (in degrees°F),

r = rain ( in inches),

If T = 80°F, r = 6 inches,

S(80, 6) = 70(80−90)(4−6) = 70(-10)(-2) = 1400 units

Hence, S(80, 6) represents the shop's daily sales when temperature is 80°F and rain is 6 inches.

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.

60 for the first and 130 for the second
