Softa [21]
The answer is
<span>a) 1000=-16t^2+1700, implies t² = -700 /-16, and t= 6.61s
b) </span><span>970= -16t^2+1700, </span><span>implies t² = -730 /-16, and t=6.75s

c)
reasonable domain of h
h is polynomial function, so its domain is R, (all real number)
its range
the inverse of h is h^-1 = sqrt (1700- t / 16), and its domain is </span>
<span><span><span>1700- t / 16>=0, so t <1700,

An aerosol can contains gases under a pressure
slavikrds [6]

Answer:

temperature on the beach = T2 = 34.56 °C

Step-by-step explanation:

We are given;

P1 = 4.5 atm

T1 = 24 °C = 24 + 273 = 297 K

P2 = 4.66 atm

Thus, P1/T1 = P2 /T2

So, T2 = P2•T1/P1

Thus, T2 = (4.66x 297)/4.5

T2 = 307.56 K

Let's convert to °C to obtain ;

T2 = 307.56 - 273

T2 = 34.56 °C

2. Help ASAP!!!!!!!!!!!!!!!!
ch4aika [34]

ANSWER

2 \times 2

EXPLANATION

The dimensions of a matrix is of the form:

Row \times  Column

The dimensions of the first matrix is

2 \times 3

The dimensions of the second matrix is

3 \times 2

Since the inner products are the same,the outer products give the dimensions of the product of the two matrices.

(2 \times 3)(3 \times 2) = 2 \times 2

Therefore the dimensions of the product is a 2×2 matrix.
