What are the coordinates of J'?

Mathematics
1 answer:
attashe74 [19]3 years ago
6 0

Answer:

F'(-\frac{10}{3},-\frac{8}{3})

or

F'(-3.33,-2.67)

Step-by-step explanation:

we know that

The coordinates of point F are (-5,-4) (see the figure)

In this problem

A dilation with a scale factor 2/3 about the origin is described using the following notation:

(x,y) ----> (\frac{2}{3}x,\frac{2}{3}y)

so

Applying the rule of the dilation to point F

F(-5,-4) ----> F'(\frac{2}{3}(-5),\frac{2}{3}(-4))

F(-5,-4) ----> F'(-\frac{10}{3},-\frac{8}{3})

F(-5,-4) ----> F'(-3.33,-2.67)

Answer:

<h2>Make the points more Appealing</h2>

Step-by-step explanation:

B. The expression has 4 factors and 0 constants.

The factors separately are:

4

a

b

(c+3)

Factors are numbers or expressions that produce a givens product.

Looking at the expression we can rewrite it as:

4 x a x b x (c+3)

The overall value with be the product of all the factors.

Literally answer any of the questions above and it’ll be the biggest help
Tcecarenko [31]

The cosine of an angle is the x-coordinate of the point where its terminal ray intersects the unit circle. So, we can draw a line at x=-1/2 and see where it intersects the unit circle. That will tell us possible values of θ/2.

We find that vertical line intersects the unit circle at points where the rays make an angle of ±120° with the positive x-axis. If you consider only positive angles, these angles are 120° = 2π/3 radians, or 240° = 4π/3 radians. Since these are values of θ/2, the corresponding values of θ are double these values.

a) The cosine values repeat every 2π, so the general form of the smallest angle will be

... θ = 2(2π/3 + 2kπ) = 4π/3 + 4kπ

b) Similarly, the values repeat for the larger angle every 2π, so the general form of that is

... θ = 2(4π/3 + 2kπ) = 8π/3 + 4kπ

c) Using these expressions with k=0, 1, 2, we get

... θ = {4π/3, 8π/3, 16π/3, 20π/3, 28π/3, 32π/3}

Algebra:please answer #1 and show work
Novay_Z [31]
So 12 mins to 600 feet
35 mins=1900 feet
find the slope which is change in top over change in bottom (aka slope) so to find do
(y1-y2)/(x1-x2)
we want, per minute, so put the time as x1 and x2
x1=12
y1=600
x2=35
y2=1900
subsitutte
(600-1900)/(12-35)=-1300/-23=56.5 per minute
the answe ris 56.5 feet per minute or the last answer
