Answer:

The required integer is -15.

Step-by-step explanation:

Given,

The temperature dropped 3°c every hour,

So, the change in temperature every hour = -3°C

Total number of hours for which the temperature were changed = 5,

Thus, the total change in temperature = change for an hour × total number of hours,

= -3° × 5

= -15°

Hence, the integer that represents the change in temperature is -15.

Answer:

$cos(33^{\circ})$

Step-by-step explanation:

Given

$sin(57^{\circ})$

Required

Determine an equivalent expression

In trigonometry:

$sin(\theta)= cos(90^{\circ} - \theta)$

In $sin(57^{\circ})$

$\theta=57^{\circ}$

Substitute $57^{\circ}$ for $\theta$

in $sin(\theta)= cos(90^{\circ} - \theta)$

$sin(57^{\circ})= cos(90^{\circ} - 57^{\circ})$

$sin(57^{\circ})= cos(33^{\circ})$

Hence, the equivalent expression is: $cos(33^{\circ})$
