The point (-3,-2) is rotated 180 degrees about the origin. what are the coordinates of its image?

den301095 [7]

Answer:

The coordinates of the image are (3,2)

Step-by-step explanation:

we know that

The coordinates of the pre-image are (-3,-2)

This point is located on III Quadrant

If the point is rotated 180 degrees about the origin

then

The image will be located on I Quadrant

The rule of the rotation is equal to

(x,y) ------> (-x,-y)

(-3,-2) -------> (3,2)

Given that P(E) = 0.38, P(F) = 0.38, and P(E ∩ F) = 0.12. Find P(E ∪ F, how do I work this out?

natulia [17]

Answer: The value of P(E∪F) = 0.64.

Step-by-step explanation:

Since we have given that

P(E) = 0.38

P(F) = 0.38

P(E∩F) = 0.12

So, we need to find the P(E∪F).

As we know the formula for the sets.

$P(E\cup F)=P(E)+P(F)-P(E\cap F)\\\\P(E\cup F)=0.38+0.38-0.12=0.64\\\\P(E\cup F)=0.64$

Hence,the value of P(E∪F) = 0.64.

Shawnee is putting $3,500 into an account earning 4.85% interest compounded quarterly. She estimates that it will take just over

Murljashka [212]

A=3,500×(1+0.0485÷4)^(4×11)
A=5,947.99

6000=3500(1+0.0485/4)^4t
Solve for t to know the time needed to reach 6000
Time=11.2
So the time needed is 11 years and 2 months
