Answer:
Water temperature in an ocean varies inversely to the water’s depth. Between the depths of 250 feet and 500 feet, the formula
T
=
14
,
000
d
gives us the temperature in degrees Fahrenheit at a depth in feet below Earth’s surface. Consider the Atlantic Ocean, which covers 22% of Earth’s surface. At a certain location, at the depth of 500 feet, the temperature may be 28°F.
The longest side in the triangle is opposite to the largest angle of this triangle. If triangle is acute, then all angles are acute. Acute angle has cosine that is positive.
Use cosine theorem to determine the cosine of the largest angle:
where
is the largest angle.
Then

Since
then

Divide this inequality by 5:

Note that
then the smallest possible whole-number value of x is 7.
Answer: correct choice is B
Answer:
A and C
Step-by-step explanation:
Since it is isosceles two sides should be equal and we already know the perimeter is 21in.
<em>5</em>+<em>5</em>+11=21in
5+<em>8</em>+<em>8</em>=21in
Answer:
Enlargement
k =
=
Step-by-step explanation:
k =
If k > 1 then its an enlargement.
If k < 1 then its a reduction
