Answer:
the answer of this is 434
V= ~ r2 h
V / h ~ = r2
3769/ 12.(3.1316) = r2
99.97 = r2
10 = r
The radius is 10
Answer:
t=0
Step-by-step explanation:
r=<
+1,
>
by differentiating the r vector component by component
r' = <2at, 1>
Two vector are orthogonal when the dot product between them is zero, so:
r'·r=0
<
+1,
>·<2at, 1>=2
+2at+t=0
common factor
t(
+2a+1)=0
Then, the only real value for t is zero.
-> t=0
Answer:
<h2>6√2</h2>
Step-by-step explanation:

Answer:
Sarah bought 30 pencils
Step-by-step explanation:
1. Let define p, as the number of pencils bought, and m, as the number of markers bought.
2.


3. Substitute p in the first equation to 3m since p=3m as defined.

plug m into equation p=3m to find the number of pencils bought
