Answer:

300

Step-by-step explanation:

→ First substitute the biggest number into it

45% of 300 =

→ Do 45 × 300

13500

→ Divide answer by 100

135

→ Therefore 45% of 300 = 135

1. The position of a particle moving along a coordinate axis is given by: s(t) = t^2 - 5t + 1. a) Find the speed of the particle

zimovet [89]

Answer: $\left | 2t-5\right |,\ 2,\ 2t-5$

Step-by-step explanation:

Given

Position of the particle moving along the coordinate axis is given by

$s(t)=t^2-5t+1$

Speed of the particle is given by

$\Rightarrow v=\dfrac{ds}{dt}\\\\\Rightarrow v=\dfrac{d(t^2-5t+1)}{dt}\\\\\Rightarrow v=\left | 2t-5\right |$

Acceleration of the particle is

$\Rightarrow a=\dfrac{dv}{dt}\\\\\Rightarrow a=2$

velocity can be negative, but speed cannot

$\Rightarrow v=\dfrac{ds}{dt}\\\\\Rightarrow v=\dfrac{d(t^2-5t+1)}{dt}\\\\\Rightarrow v=2t-5$

If one angle of a triangle is 63 and the other two are 7x degrees and 6x degrees what is X worth

Black_prince [1.1K]

Answer:

x = 9

Step-by-step explanation:

Sum of all angles of a triangle = 180

63 + 7x + 6x = 180

63 + 13x =180

13x = 180 - 63

13x = 117

x = 117/13

x = 9
