How do u solve the following equation: |r|=1

vredina [299]

You're almost looking at the solution. Almost.

If it only said " r = 1 ", then that would be the solution right there.

But it says " | r | = 1 ", so there's a little more to it.

'r' can be either +1 or -1 and that equation will be a true statement.

So +1 and -1 are both solutions.

sveticcg [70]

Answer:

$\frac{x}{y}=1.3$

Step-by-step explanation:

<u>Informação recuperada:</u>

(UFRGS) Se 10x = 20y , atribuindo 0,3 para log 2 , então o valor de x/y é

1) Primeiro, passando o 10 para o 2º membro como base do logaritmo:

$10x=20y \Rightarrow x=log_{10}20y$

2) Aplicando a propriedade do produto de logaritmo:

$log(AB)= logA+logB$

$x=log_{10}20y \Rightarrow x=log(2+10)y\Rightarrow x=(0.3+1)y \Rightarrow x=1.3y$

3) Como quero o quociente divido ambos os lados por y

$\frac{x}{y}=\frac{1.3y}{y}\Rightarrow \frac{x}{y}=1.3$

Confused!! consider the polar axes with the points plotted below. Write the coordinates of point A in polar form. Be sure to wri

irinina [24]

Point A is on the 4th circle from the center, each circle has a radius of 1, so the 4th circle has a radius of 4. The point is also on the angle labeled 5PI/6.

The polar coordinate would be (4, 5PI/6)

Point C, you are given (-3,pi/3)

Because the radius is positive find the 3rd circle, which would be r = 3, Then find where PI/3 is on the circle and find the value opposite that which is 4pi/3

6. Trail Bike Rentals charges a $16 fixed fee plus $8 per hour for renting a bike. Matt paid $72

Naddik [55]

Answer:

7 hours

Step-by-step explanation:

The total amount is the flat fee plus the amount per hour times the number of hours

16 + 8h = 72

Subtract 16 from each side

16+8h-16 = 72 -16

8h = 56

Divide by 8

8h/8 = 56/8

h = 7

7 hours
