What is the value of x if g^x-1-2= 25?
SVETLANKA909090 [29]

Answer:

Third option: x=\frac{5}{2}

Step-by-step explanation:

<h3> The correct exercise is attached.</h3>

The equation given is:

9^{x-1}-2=25

 The steps to find the value of "x" are shown below:

1. Add 2 to both sides of the equation:

9^{x-1}-2+2=25+2\\\\9^{x-1}=27

2. Descompose 9 and 27 into their prime factors:

9=3*3=3^2\\27=3*3*3=3^3

3. Substitute them into the equation:

3^{2(x-1)}=3^3

4. Knowing that If a^n=b^m, then n=m, we get:

2(x-1)=3

5. Apply Distributive property:

2x-2=3

6. Add 2 to both sides:

2x-2+2=3+2\\\\2x=5

7. Divide both sides of the equation by 2:

\frac{2x}{2}=\frac{5}{2}\\\\x=\frac{5}{2}

The graph shows the solution to the initial value problem y'(t)=mt, y(t0)= -4
Charra [1.4K]
y'(t)=mt&#10;\\&#10;\\ y=\int {mt} \, dt=m \int{t} \,dt=m \frac{t^2}{2} +C \\ \\y= \frac{mt^2}{2}+C

Now find equation of the graph. It passes through the point (2,3), and intersects y-axis at -2.

y=at^2+b&#10;\\&#10;\\3=a\times 2^2-2&#10;\\&#10;\\3=4a-2&#10;\\&#10;\\5=4a&#10;\\&#10;\\a= \frac{5}{4} &#10;\\&#10;\\y=\frac{5}{4} t^2-2 \\ \\y= \frac{m}{2} t^2+C&#10;\\ \\  \frac{m}{2} = \frac{5}{4} &#10;\\&#10;\\m= \frac{5}{2} &#10;\\&#10;\\C=-2&#10;\\&#10;\\y(t_0)=-4&#10;\\&#10;\\-4= \frac{5}{4} t_0^2-2&#10;\\&#10;\\ -2= \frac{5}{4} t_0^2&#10;\\&#10;\\ t_0^2=- \frac{8}{5} &#10;\\&#10;\\t_0=\pm \sqrt{- \frac{8}{5} }
