Answer:
(x,y)=(2,12).
Step-by-step explanation:
Let's find the answer using the given equations:
y1=5x+2
y2=-3x+18
Using the intersection method:
y1=y2 so:
5x+2=-3x+18
5x+3x=18-2
x=16/8=2
Using x=2 in the first equation we have:
y1=5*(2)+2=12
So, the answer is (x,y)=(2,12).
Let's check our answer:
y1=5x+2
12=5*(2)+2
12=12
y2=-3x+18
12=-3*(2)+18
12=12
Answer:
= 30.144 km²
Step-by-step explanation:
Area of a sector is given by the formula;
θ/360 × πr², where θ is the angle subtended by the arc to the center of the circle, and r is the radius.
Area = 54/360 × 3.14 × 8 × 8
= 30.144 km²
If giraffes can run 46.93 seconds, it is equivalent to 46.93(1). So, multiply 46.93 by 1.8
You get 46.93(1.8) = <span>84.474 feet per second.</span>
