just add you the numbers and you will get the answer
6 adults - 6*39.50= 237
11 kids. - 11*31= 341
341 + 237 = 578
Answer:
His acceleration is 1.8m/s²
Step-by-step explanation:
acceleration, a = velocity, v / time, t
Velocity = 18m/s, unit is in m/s
time = 10 seconds, unit is in s
Therefore, a = 18m/s/10s = 1.8m/s²
If the point ( x, √3/ 3) is on the unit circle, then the value of x will be √2/ 3. The correct option is D.
<h3>What is the equation of the circle with radius r units, centered at (x,y)?</h3>
If a circle O has a radius of r units length and it has got its center positioned at (h, k) point of the coordinate plane,
then, its equation is given as:
The equation of unit circle is
Thus, x = √2/ 3
If the point ( x, √3/ 3) is on the unit circle, then the value of x will be √2/ 3.
