Answer:
Area of semi circle = 1/2 ×πr²
π = 3.142 and r = if 10cm
Area = 1/2 × 3.142 × 10²
Area = 1/2 × 3.142 × 100
Area = 3.142 × 50
Area = 157.10cm²
Step-by-step explanation:
Answer:
Yes.
Step-by-step explanation:
Though x and y can be achieved in a system of equations. The equation
x (t)=0.0411905(t^2)+(-0.164619)t+28.0114
And
y (t)=-0.024127(t^2)+(-0.591143)t+(-87.4403)
Are not system of equations but rather two different models of equations. Nevertheless
To find t in the first equation, x(t) has to be equal to zero.
When the t is substituted in the second equation, t will completely disappear. Given the value of y(t) and vice versa.
Answer:
Alicia runs 21120 feet per day
Step-by-step explanation:
24 miles/6 days 5280 ft/1 mile
you would then multiply 24 by 5280 to get 126760
and afterwards you would divide 126760 by 6 to get 21120 ft per day
