Answer:
can someone teach me that
Step-by-step explanation:
The temperature was -14°F at 8 a.m.
At noon is was 10 degrees warmer - the temperature increase was 10°F
-14°F + 10°F = -4°F
The tempertaure increase between noon and 4 p.m. was twice the previous increase in temperature, which was 10°F.
10°F x 2 = 20°F
We want to know the temperature at 4 p.m. so we just add it up to the previous result.
-4°F + 20°F = 16°F
16°F is the correct answer
Answer:
(-6,-7)
Step-by-step explanation:
Apply the midpoint formula!
Let
A-----> area of a sector of the circle
∅<span> -----> central angle is in radians
</span>r------> the radius of the circle
we know that
the ratio of a sector area A to the circle area is equal to the ratio of the central angle to the measure of a full rotation of the circle. A full rotation of the circle is 2*pi radians
so
A/(pi*r²)------> ∅/(2*pi)
multiply by (pi*r²)
A=[∅/(2*pi)]*(pi*r²)-------> A=(∅/2)*r²
therefore
the answer in the attached figure
