If all of the side are equal, that would mean that it is an equilateral triangle. Meaning all of the angles are the same measure. A triangle equals 180 deg. So you divide that by 3 to find each individual side of the equilateral triangle. Therefore m3=60 degrees.

In each of Problems 5 through 10, verify that each given function is a solution of the differential equation.

WARRIOR [948]

Answer:

For First Solution: $y_1(t)=e^t$

$y_1(t)=e^t$ is the solution of equation y''-y=0.

For 2nd Solution: $y_2(t)=cosht$

$y_2(t)=cosht$ is the solution of equation y''-y=0.

Step-by-step explanation:

For First Solution: $y_1(t)=e^t$

In order to prove whether it is a solution or not we have to put it into the equation and check. For this we have to take derivatives.

$y_1(t)=e^t$

First order derivative:

$y'_1(t)=e^t$

2nd order Derivative:

$y''_1(t)=e^t$

Put Them in equation y''-y=0

e^t-e^t=0

0=0

Hence $y_1(t)=e^t$ is the solution of equation y''-y=0.

For 2nd Solution:

$y_2(t)=cosht$

In order to prove whether it is a solution or not we have to put it into the equation and check. For this we have to take derivatives.

$y_2(t)=cosht$

First order derivative:

$y'_2(t)=sinht$

2nd order Derivative:

$y''_2(t)=cosht$

Put Them in equation y''-y=0

cosht-cosht=0

0=0

Hence $y_2(t)=cosht$ is the solution of equation y''-y=0.

The ratio of boys to girls in a group is 3 to 1 is there are 28 more boys then girls workout how many people their are it total

worty [1.4K]

Answer:

56 total

Step-by-step explanation:

Let the number of girls = x

Let the number of boys = 3x

x 1

=== = ==========

x + 28 3

Cross multiply

3x = x + 28 Subtract x from both sides

3x - x = 28 Combine

2x = 28 Divide by 2

x = 28/2

x = 14

Girls = 14

Boys = 14 + 28 = 42

Is the ratio 3 to 1?

42/14 = 3/1 Yes it does

Total number

14 + 42 = 56
