Answer:

A = (5s^2t - 9st) (3t + 1)

Step-by-step explanation:

(5s^2 - 9s) (3t^2 + t)

= 15s2t^2 + 5s^2t - 27st^2 - 9st

= 5s2t (3t + 1) - 9st (3t + 1)

= ( 5s^2t - 9st) (3t+1)

If 0.65 AU equal 1 inch how much would 0.05 AU equal and explain.

mart [117]

Answer:

0.05 AU corresponds to the 0.0769 Inches(This calculation is not possible in real time world)

Step-by-step explanation:

Given:

0.65 corresponds to 1 inch

To Find:

0.05 AU corresponds to how many inches.

Solution:

The AU is astronomical unit which is preferred as the mean distance between earth and sun.

AU is too big unit and used in space distance calculation.

But here for mathematical calculation,

0.65 AU corresponds to 1 inch

then 0.05 AU corresponds to x inch(es)

Now cross multiplying the quantities we get ,

0.65x=0.05*1

x=0.05/0.65

x=0.0769 inches corresponds to 0.05 AU

(Preferred for this example only)

(Remember that this calculation is hypothetical and practically incorrect to use it).

Write a linear function to describe the sequence. Explain your function. The first 5 terms of an arithmetic sequence are shown.

zimovet [89]

Answer:

The linear function is;

Tn-1 = Tn + 3

What this mean is that to get the term before the present term, we add 3 to the present term

Step-by-step explanation:

Here, we want to write a liner function to describe the function

As we can see from the numbers listed,

the next term is simply obtained by deducting 3 from the previous term

We can write this as:

Tn-1 = Tn + 3

Where Tn is the next term and Tn-1 is the previous term

What the function is saying is that to get the term before the present term, we add 3 to the present term

Jason states that Triangle A B C is congruent to triangle R S T. Kelley states that Triangle A B C is congruent to triangle T S

Brilliant_brown [7]

Answer:

The correct option is;

Jason's statement is correct. RST is the same orientation, shape, and size as ABC

Step-by-step explanation:

Here we have

ABC = (2, 1), (3, 3), (4, 1)

RST = (-4, -2), (-3, 0), (-2, -2)

Therefore the length of the sides are as follows

AB = $\sqrt{(2-3)^2+(1-3)^2} = \sqrt{5}$

AC = $\sqrt{(2-4)^2+(1-1)^2} =2$

BC = $\sqrt{(3-4)^2+(3-1)^2} = \sqrt{5}$

For triangle SRT we have

RS = $\sqrt{(-4-(-3))^2+(-2-0)^2} = \sqrt{5}$

RT = $\sqrt{(-4-(-2))^2+(-2-(-2))^2} = 2$

ST = $\sqrt{(-3-(-2))^2+(0-(-2))^2} = \sqrt{5}$

Therefore their dimensions are equal

However the side with length 2 occurs between (2, 1) and (4, 1) in triangle ABC and between (-4, -2) and (-2, -2) in triangle RST

That is Jason's statement is correct. RST is the same orientation, shape, and size as ABC.
