Answer:

$39.8^{\circ} C$

Step-by-step explanation:

We are given that the temperature each hour in Elma Texas on October 1 is modelled by the equation

$t(h)=10cos(15h-10)^{\circ}+30$

Where h=Hour of the day with 0 meaning midnight

t=Temperature in degree Celsius

We have to find the temperature on October 1.

Substitute h=0

$t(0)=10cos(15(0)-10)+30$

$t(0)=10cos(-10)+30$

$t(0)=39.8^{\circ} C$

Hence, the temperature in Elma on October 1= $39.8^{\circ} C$

I'm not sure if that is supposed to be 7 or -7 If it's -7: 1<2n-5<-7 +5 +5 +5 Add 5 to all parts of the inequality get 2n by itself 6<2n<-2 /2 /2 /2 Divide all parts by 2 to isolate the variable 3

What's the value of x? Enter your answer in the box.<br> x = {}

Pani-rosa [81]

All three angles on a triangle always equal 180°.

Example: 100°+40°+40°=180°

102+39=141°

180-141=39°

x = 39°

Pat shows that 16 1/2= the square root of 16. What is one possible way pat could have shown this correctly?

kifflom [539]

<h3>Answer: Choice C</h3>

The base 16 is the same as 4*4.

From there, the rule $(a*b)^c = a^c*b^c$ is used to get $(4*4)^{1/2} = 4^{1/2}*4^{1/2}$

Afterward, the exponents are added getting 1/2+1/2 = 2/2 = 1. The rule is $a^b*a^c = a^{b+c}$ which only works if the bases are both the same.
