1 answer:

5 0

Let's say that $x+3=2x-1$
First, you want all of the variables on one side and the rest on the other;
$x+3=2x-1\\
3-(-1)=2x - x\\
3+1=x\\
x=4$

The gravitational force exerted by the planet Earth on a unit mass at a distance r from the center of the planet is:

jolli1 [7]

Answer:

Yes, F is a continuous function of r

Step-by-step explanation:

We are given that

When r<R

$F(r)=\frac{GMr}{R^3}$

$r\geq R$

$F(r)=\frac{GM}{r^2}$

Where M=Mass of the earth

R=Radius of earth

G=Gravitational constant

We have to find the function is continuous of r or not.

LHL

$\lim_{r\rightarrow R-}\frac{GMr}{R^3}=\frac{GMR}{R^3}=\frac{GM}{R^2}$

RHL

$\lim_{r\rightarrow R+}\frac{GM}{R^2}=\frac{GM}{R^2}$

$F(R)=\frac{GM}{R^2}$

When a function is continuous at x=a

Then, LHL=RHL=f(a)

RHL==LHL=F(R)

Hence, the function is continuous of r.

In kite PQRS, m∠TQP=63°. Identify m∠QPT.

mario62 [17]

Assuming m<PTQ is a right angle (measuring 90°) and angle TQP is already marked as 63° while knowing there are 180° in a triangle, you would take 180°- 63°- 90°= 27

Ludmilka [50]

The probability that none of the four have been vaccinated is
(1-0.63)^4 = 0.01874161

The probability that at least one has been vaccinated is the complement of this,
≈0.9813
