HELP PLEASE ILL TRY TO MARK U BRAINLIEST
Anon25 [30]

Step-by-step explanation and answer:

For this you just need to plug in x for y = f(1/5x)

1/5(-4) = -4/5 or -0.8

1/5(-1) = -1/5 or -0.2

1/5(0) = 0

1/5(3) = 3/5 or 0.6

1/5(6) = 6/5 or 1.2 or 1 1/5

This is a Differential Equations problem, I only need help on part 1 from question five. I need steps as well, thank you.
jolli1 [7]

Answer:

a) y(t) =  \sqrt{2t + 1 }

b) 1.5 hours after thickness will be 2 inches.

Step-by-step explanation:

\frac{dy}{dt}  =  \frac{1}{y}   \\   \\ ydy = dt  \\ \\ integrating \: both \: sides \\   \\  \int y \: dy =  \int 1 \: dt \\  \\  \frac{ {y}^{2} }{2}  = t + c \\  \\  {y}^{2}  = 2t + 2c \\  \\ y (t)=  \sqrt{2t + 2c} ...(1) \\  \\ a)  \:  \: \: plug \: t = 0 \: in \: (1) \\  \\  y (0)=  \sqrt{2(0) +2 c} \\  \\ y (0)=  \sqrt{0 +2 c} \\  \\ 1 =  \sqrt{2c}  \:  \: ( \because \: y (0)=1) \\  \\  2c = 1   \:  \implies \: c =  \frac{1}{2} \\  \\ plug \: c = \frac{1}{2} \: in \: (1) \\  \\ y(t) =  \sqrt{2t + 2 \times  \frac{1}{2} } \\  \\  \huge \:  \red {y(t) =  \sqrt{2t + 1 } } \\  \\b) \:  \:  plug \: y(t) = 2 \: in \: above \: equation \\  \\ 2 =  \sqrt{2t + 1}  \\  \\ 4 = 2t + 1 \: \\  (squaring \: both \: sides) \\  \\ 4 - 1 = 2t \\  \\ 2t = 3 \\  \\ t =  \frac{3}{2}  \\  \\ t = 1.5 \: hours \\

sdas [7]

Answer: 7:41 am

Step-by-step explanation:

It takes Ebru 13 minutes to bike to school but if she walks it would take her twice at long.

= 26 minutes

If she leaves the house at 7:15 , she will arrive at:

= 715 + 26

= 7:41 hours

Allisa [31]

Given:

One time payment, <em>p </em>= $300

Payment per month, <em>q = </em>$65

Number of months paid, <em>n</em> = 5

The objectiv is to find the amount she paid in 5 months.

Let <em>x </em>be the amount she paid in 5 months. Then the the formula is,

x=p+nq

Let's substitute the values.

\begin{gathered} x=300+5(65) \\ x=300+325 \\ x=625 \end{gathered}

Hence, total amount paid in 5 months is $625.
