Which statement describes the solution to the equation a+5(2a−1)+3=11a−2 ?A.The equation has no solution.

b. The equation has exactly one solution, a=2 11 .

C. The equation has exactly one solution, a=−4 .

D. The equation has infinitely many solutions.

Answers

Answer 1
Answer: a+5(2a-1)+3=11a-2
First thing to do is distribute
5*2a=10a
5*-1=-5
a+10a-5=11a-2
Add the similar numbers together
11a-5=11a-2
Then subtract 
11a-11a
-5=-2
This equation has no solutions
If it had infinity solutions then both numbers on each side would equal the same, ex: -5=-5 
Answer 2
Answer: 1st distribute

a + 10a - 5 + 3 = 11a -2

Then combine like terms

11a-2 = 11a-2

0=0

Infinite solutions

Start at 12 create a pattern that multiplies each number by 4

Answers

So,

Basically, you're asking us to start a pattern with 12 and multiply it for every subsequent term.
12, 12 * 4, 12 * 4^2, 12 * 4^3, ...
12, 48, 192, 384, ...

So the geometric sequence will look like this:

12 * 4^(n-1)

A geometric sequence is a sequence where the next terms are found by performing multiplication or division.  In this case, we are multiplying by 4.  This is opposed to an arithmetic sequence, where we are adding or subtracting.

To show that this geometric sequence works, let's try to find a few terms.  To find the nth term, you just have to plug in the number of the term into the expression for n.

For instance, find the first term.  This is the resulting expression:
12*4^(1-1)=12*4^0=12*1=12

Let's try a few more terms.  The 2nd term:
12 * 4^(2-1) = 12*4^1=12*4=48

The 3rd term:
12 * 4^(3-1) = 12*4^2=12*16=192

And that's how the geometric sequence works.

two unidentified flying discs are detected by a receiver, the angle of elevation from the receiver to each disc is 38.48 degrees. The discs are hovering at a direct distance of 826metres and 1.296km from the receiver. Find the difference in height between the two flying discs.

Answers

Answer:

292.45 m

Step-by-step explanation:

Both disk are at an angle of 38.48°

From the image below we calculate as,

For disk B, direct distance is 1.296 km from receiver = 1296 m

Vertical height from ground will be = 1296 x sin38.48 = 806.42 m

For disk A, direct distance is 826 m from receiver

Verival height above ground = 826 x sin38.48 = 513.97 m

Difference in height between disks is 806.42 - 513.97 = 292.45 m

What is the algebraic expression for -7 times the quantity w minus 6

Answers

The expression is -7(w-6)

It's stating that the value of w minus 6 (w-6), is multiplied by -7.
To solve, you distribute the -7 to the variable w and the value -6 and you get

-7w+42

Jen motorboat travels at a speed of 13mph in still water. Booth River flows at a speed of 3mph. How long will it take Jen to travel 11 mi upstream? 11mi downstream

Answers

Answer:

Upstream 1.1 hours and down stream 0.6875 hours.

Step-by-step explanation:

Jen motorboat travels at a speed of 13 mph in still water.

Now, the speed of river flows is 3 mph.

Therefore, the upstream speed of the boat is (13 - 3) = 10 mph and the downstream speed of the boat will be (13 + 3) = 16 mph.

Therefore, to travel 11 miles upstream Jen will take (11)/(10) = 1.1 hours.

And to travel 11 miles down stream Jen will take (11)/(16) = 0.6875 hours. (Answer)
