Answers

Answer 1

Answer: $E= (1)/(2) mv^2+mgh\ /\cdot2\n\n2E=mv^2+2mgh\n\n2E=m(v^2+2gh)\ /:(v^2+2gh)\n\nm= (2E)/(v^2+2gh)$

Answer 2

Answer: $E= (1)/(2)mv^2+mgh \ \ / \cdot 2\n \n 2 \cdot (1)/(2)mv^2+ 2\cdotmgh = 2\cdot E\n \n mv^2+2mgh= 2E \n \nm(v ^2+2gh)= 2E \n \n m=(2E)/(v ^2+2gh)$

Answer:

B 2x-31 = -2x-31

Step-by-step explanation:

A is exactly the same on the left side as the right so it has infinite solutions

B 2x-31 = -2x-31

Add 2x on each side

2x+2x-31 = -2x+2x-31

4x -31 = 31

Add 31

4x =62

This has one solution

C 2x+31 = 2x-31

Subtract 2x from each side

31 = -31

This is never true so it has no solutions

D 2x-2 = 2x-31

Subtract 2x from each side

-2 = -31

This is never true so it has no solutions

Answer:

Step-by-step explanation:

2x - 31 = -2x - 31

4x = 0

x = 0

x = 0 is the only solution

A certain bank offers a car loan with a fixed annual interest rate. Justine applied for the loan and used the entire amount to buy a car worth $43,000. He had to pay the bank for five years for a total amount of $51,600. How much would be the yearly interest if Justine borrowed $50,000 instead? *0 points

Answers

Answer: $10000

Step-by-step explanation:

From the question,

Principal = $43000

Time = 5 years

Rate = Unknown

Simple Interest = $51,600 - $43000 = $8600

We need to calculate the rate of interest which will be:

Interest = PRT/100

8600 = (43000 × 5 × Rate) / 100

Cross multiply

8600 × 100 = 215000 × Rate

Rate = 860000 / 215000

Rate = 4%

Assuming Justine borrowed $50,000 instead, the yearly Interest will be:

= (50000 × 5 × 4%)

= 50000 × 5 × 0.04

= $10000

6^2+17+12 help me plz.

Answers

6^2 + 17 + 12

First, let's start with $6^(2)$ . Basically, the '2' above the 6 indicates that the number appears twice in multiplying. $6^(2)$ can be described as 6 × 6 as well. 36 should be your answer for 6 squared.
$6^(2) = 6 * 6 = 36$

Second, our problem should look like: 36 + 17 + 12. One can simply do this on a calculator or count on their fingers. Once you add all of the numbers up, you should get 65.

Answer: $\fbox {65}$

6 squared is 36 because 6x6=36.
Then all you have to do is 36+17+12
which should be: 65

Find the value of t in the equation t+5+3t=1

Answers

$t+5+3t=1\nt+3t+5=1\n4t+5=1\n4t+5-5=1-5\n4t=1-5\n4t =-4\n\n\boxed{\bf{t=-1}}$

First combine like terms. 1t+3t=4t
5+4t=1
Now subtract 5 from both sides.
4t=-4
Now divide both sides by 4.
t=-1
To check, let's plug in -1 for t.
-1+5+3*-1=
3*-1=-3
-1+5+-3=1
t=-1
