Answer:
The velocity is 17 m/s
Step-by-step explanation:
To find the velocity, we find the first differential of the displacement
That will be
S’(t) = 16t + 1/t
We simply proceed to replace t with 1
That will give;
16(1) + 1/1
= 16 + 1 = 17 m/s
Answer: 20, 300.011s significant digit is 8 SF
Step-by-step explanation:
13 = 13
45= 3* 3* 5
GCF (13, 45)= 1.
Because GCF (13, 45)= 1, 13 and 45 are relatively prime. Therefore, 13/45 in its simplest form is still 13/45~
Answer:
y =
The focus of the solar oven's reflector is (0,a)
Step-by-step explanation:
The missing figure( i.e diagram) from the question is attached below:
Now ; given that :
The focus of the sun's rays is at a point L = 5 inches away from the vertex of the reflector. Also the distance of the parabolic curve be a= L = 5
So the equation for a cross section of the oven's reflector with its focus on the
positive y axis and its vertex at the origin is expressed as:
x² = 4 L y
x² = 4 (5) y
x² = 20 y
y =
The focus of the solar oven's reflector is (0,a)
The incorrect one is 35 × 10⁵
it can be written as :
