multiply 1.8 by 4.5 then subtract from the starting temperature
1.8 *4.5 = 8.1 degree change
4.6 - 8.1 = -3.5
it was negative 3.5 degrees
Answer is B
When two terms are directly next two each other, they are being multiplied.
The answer is 5n
Let
Eqn 1 be <span>8x = 2y + 5
</span><span>
And,
</span><span>3x = y + 7
</span>therefore
Eqn 2 is <span> x= 1/3(y+7)
</span>
Sub 2 into 1 gives:
8(1/3(y+7)) = 2y + 5
8/3(y) + 56/3 = 2y + 5
2/3(y) = –41/3
2y=–41
y= –41/2
X= –9/2.
Therefore, <span>{(-9/2, -41/2)} is your solution set. As the notation is equal to (x,y)</span>
Develop <span> cos(</span>π<span>/3 + h) =
= 1/2 -h.</span>√3/2 - h²/4√3 +h³/4√3 + h⁴/48 - h⁵/80√3 - h⁶/1440 +....
