erma4kov [3.2K]
At the Children's Theater, each row can seat 25 people. So, if there are 63 rows, there would be the total of 1,575 people.

At the Bartell Theater, which can seat 2,048 people, there are 64 rows. Each row can seat 32 people.

So, 7 more people are seated in each row at the Bartell Theater than at the Children's Theater.

The​ temperature, T, in degrees​ Fahrenheit, in a​ car's radiator during the first 4 minutes of driving is a function of​ time,
devlian [24]

Answer:

Step-by-step explanation:

T = 5.8t² + 14t + 32 ( 0 ≤ t ≤4 )

a ) when t = 0 ( when car is turned on )

T = 32 ° F .

b ) When t = 2

T = 5.8t² + 14t + 32

= 5.8 x 2² + 14 x 2 + 32

= 23.2 + 28 + 32

= 83.2 ° F

c )

T = 80 ;  to find t = ?

80 = 5.8t² + 14t + 32

5.8t² + 14 t - 48 = 0

t = \frac{-14+/-(14^2-4\times 5.8\times -48)^\frac{1}{2} }{2\times 5.8}

t = 1.9 minutes  . approx .
