Answer:
b. 14 + (112 ÷ n)
Step-by-step explanation:
En esta pregunta la opcion que deberiamos elegir seria 14 + (112 ÷ n). En esta expresion primero se divide 112 por algun numero que es representado por el variable n. Luego de obtener el cociente de esta division, se le agrega 14 al cociente. Esto nos daria un valor nuevo y representa perfectamente la frase en esta pregunta... catorce más que el cociente de ciento doce y algún número
Answer: The area of the cross section is 2 cm^2.
If I am understanding your problem correctly, we are just looking for the area of the grey rectangle, which is the cross section.
The length and width of this gray rectangle are already given to us. The are 1 and 2. Just multiply them to get the area.
1 x 2 = 2 cm^2
A
The velocity is found by differentiating the given cubic.
x'(t) = 2t^3 - 15t^2 + 24t This is the distance
x'(t) = 6t^2 - 20t + 24 This is the velocity (first derivative)
x"(t) = 12t - 20 This is the acceleration (second derivative)
x'(2) = 6(2)^2 - 20*2 + 24
x'(2) = 24 - 40 + 24
x'(2) = 48 - 40
x'(2) = 8 units per second.
x"(2) = 12(2) - 20
x"(2) = 24 - 20
x"(2) = 4 units per second^2
B
at t = 2 the acceleration is positive. That's a pretty good indication that the velocity is increasing.
C
When x(t) is minus, then the particle is moving left.
At t = 0 the object is not moving (x(t) = 0)
Any value less than 0 and the object is moving left. Try a couple of values.
x(-1) = 2(-1)^3 - 15(-1)^2 +24(-1) Whatever that is is minus.
t < 0 will make the object move left.
You asked your question yesterday so you don't need an answer anymore
Answer:
400
Step-by-step explanation:
angles that are coterminal with the angle 400? => 4000 and 7600 are two positive coterminal angles.
