Solve the initial value problem: y'(x)=(4y(x)+25)^(1/2) ,y(1)=6. you can't really tell, but the '1/2' is the exponent
goblinko [34]

Answer:

y(x)=x^2+5x

Step-by-step explanation:

Given: y'=\sqrt{4y+25}

Initial value: y(1)=6

Let y'=\dfrac{dy}{dx}

\dfrac{dy}{dx}=\sqrt{4y+25}

Variable separable

\dfrac{dy}{\sqrt{4y+25}}=dx

Integrate both sides

\int \dfrac{dy}{\sqrt{4y+25}}=\int dx

\sqrt{4y+25}=2x+C

Initial condition, y(1)=6

\sqrt{4\cdot 6+25}=2\cdot 1+C

C=5

Put C into equation

Solution:

\sqrt{4y+25}=2x+5

or

4y+25=(2x+5)^2

y(x)=\dfrac{1}{4}(2x+5)^2-\dfrac{25}{4}

y(x)=x^2+5x

Hence, The solution is y(x)=\dfrac{1}{4}(2x+5)^2-\dfrac{25}{4} or y(x)=x^2+5x

Can there be more than one mean or mode in a math problem??
astraxan [27]

Math. When no number occurs more than once in a data set, there is no mode. If each of two numbers occurs twice, we say the set is bimodal.

Simplify the sum.<br> (4u3 + 4u2 + 2) + (6u3 – 2u + 8)
WARRIOR [948]

Answer: 10u3 + 4u2 - 2u + 10

Step-by-step explanation:

( 4u3 + 4u2 + 2) + ( 6u3 - 2u + 8)

opening the bracket

4u3 + 4u2 + 2 + 6u3 - 2u + 8

collecting like terms

4u3 + 6u3 + 4u2 - 2u + 2 + 8

10u3 + 4u2 - 2u + 10
