The label on the car's antifreeze container claims to protect the car between −40°C and 125°C. To convert Celsius temperature t
noname [10]
The key word is "between."  Example: a number x is between 5 and 17.  Translation:  5 < x < 17.

You want the Celsius temperature to be between -40 and 125.

-40\ \textless \ \frac{5}{9}(F-32)\ \textless \ 125

The second answer choice is correct.
The first answer choice is in the wrong order; it would mean that -40 > 125. Nope!
The third answer choice is "one-sided"; it says the Celsius temperature is larger than -40 but fails to mention the upper limit of 125.
The fourth answer choice is "one-sided," too. It says the Celsius temperature is less than 125 but doesn't mention the lower limit of -40.

I hope this helps a lot!

In right triangle JFK sin(52)= cos(5x-2). What is the measure of the smallest angle in the triangle?
jeyben [28]

Answer:

48°

Step-by-step explanation:

Given the trigonometry equation

sin(52)= cos(5x-2)...1

According to the quadrant:

Sin(θ) = cos(90-θ)

Sin52 = cos(90-52)

Sin52 = cos48... 2

Substituting 2 into 1:

Cos48 = cos(5x-2)

48 = 5x-2

5x = 48+2

5x = 50

x = 10°

The smallest of the angle will be angle 5x-2 = 5(10)-2

= 50-2

= 48°

HELP NEEDED!
Ilia_Sergeevich [38]

Answer:

x = 12.6

Step-by-step explanation:

Sum of measure of all the arcs of a circle = 360°

m(arc CD) + m(arc CED) = 360°

Since, m(arc CED) = (20x)°

And m(arc CD) = (8x + 6)°

By substituting these measures in teh expression,

(20x)° + (8x + 6)° = 360°

(20x + 8x) + 6 = 360

28x = 360 - 6

28x = 354

x = \frac{354}{28}

x = 12.64

x = 12.6
