What is 2.5 x 7/10 =? and how did you get the answers?
Ivan

Answer:

1.75 or  \frac{35}{2}

Step-by-step explanation:

2.5 * 7/10 is just like 2.5 * 0.7

so 2.5 * 0.7 = 1.75

You could also convert 2.5 to fraction which is 25/10

so you would have \frac{25}{10} * \frac{7}{10} = \frac{175}{100} reduced would  equal \frac{35}{2}

How this helps you! :)

Could you please mark this answer as brainiest?

It would help me!

Thank you!

Complete the solution of the equation. find the value of y when x equals to 28<br><br> x+3y=28
Leno4ka [110]

Answer:

y=0

Step-by-step explanation:

If x equals 28 then substitute it in the equation, 28+3y=28

Next, subtract 28 from both sides, 3y=0

Now that you have that its simple, y must equal 0

A one-parameter family of solutions of the DE P' = P( 1 - P) is given below. P = c1et/1 + c1et Does any solution curve pass thro
topjm [15]

Answer:

a. The curve P(t) = -\frac{6e^t}{5-6e^t} passes through the point (0, 6)

b. No solution of the curve P(t) passes through the point (0, 1)

Step-by-step explanation:

Consider the family of the solution of DE P' = P(1 - P) is P = \frac{c_1e^t}{1 + c_1e^t}

a. If any solution passes through the point (0, 6), then there is c_1 such that the point (0, 6) satisfies the solution P = \frac{c_1e^t}{1 + c_1e^t}

Substitute t = 0, P = 6 in P = \frac{c_1e^t}{1 + c_1e^t} and then solve the equation to obtain c_1

P(t) = \frac{c_1e^t}{1 + c_1e^t}\\P(0) = \frac{c_1e^0}{1+c_1e^0}\\ 6 = \frac{c_1}{1 + c_1}\\ c_1 =  -\frac{6}{5}

Therefore, the curve P(t) = -\frac{6e^t}{5 - 6e^t} passes through the point (0, 6)

b.  If any solution passes through the point(0, 1), then there is c_1 such that the point (0, 1) satisfies the solution P = \frac{c_1e^t}{1+c_1e^t}

P(t) = \frac{c_1e^t}{1 + c_1e^t}\\ P(0) = \frac{c_1e^0}{1 + c_1e^0}\\ 1 = \frac{c_1}{1+c_1} \\1 + c_1 = c_1

this is not possible

Hence, there is no curve P(t) that exists which passes through the point (0, 1)
