Answer:
7π M squared
Step-by-step explanation:
<em>Since a whole circle is 360°, and we need to find 60° of this circle, we are basically wanting to find 
th of the circle.</em>
<em />
Area is given as 42π M squared, so 1/6th of that is 
THus, the area is 7π M squared
Since it is parallel, the slopes are equal.
The equation of required line is:
where, $c$ is some constant we have to determine using additional conditions.
The condition is that the line passes through $(-2,4)$
Put (-2,4) in our equation.
$5(-2)+2(4)=c=(-10)+8=-2$
Hence, $c=-2$
The final equation is: $\boxed{5x+2y=-2}$
Convert this to the form in the options.
Answer is y=-5/2 x-1
The answer is 124 cm

Since x represents the length (in meters), the width, which is 7 meters greater, is x +7. The product of these dimensions is the area (in square meters):
x(x +7) = 170
In standard form, the quadratic is ...
x² +7x -170 = 0
The problem can be represented by the the exponential growth formula which is :
Where: t ⇒ time , A ⇒ initial amount , r ⇒ rate of increase
P(t) ⇒ predicted amount at the end of t.
For the given problem:
initial amount = A = $278,640
<span>predicted increase in value per year = 4% =0.04
</span>
<span>∴ r = 1 + 0.04 = 1.04
</span>
<span>for t = 18 years
</span>
∴
<span />
Rounding to the nearest dollar ⇒ ∴ P(t) = <span>564,474
</span>
So, the predicted value of David's home in 18 years = $564,474
So, The correct option is <span>
$564,474</span>
