Which exponential equation is equivalent to the logarithmic equation below?

julsineya [31]

Answer:

$\implies\boxed{ 10^a = 300 }$

Step-by-step explanation:

We are provided logarithmic equation , which is ,

$\implies log_{10}^{300}= a$

Here we took the base as 10 , since nothing is mentioned about that in Question .

Say if we have a expoteintial equation ,

$\implies a^m = n$

<u>In</u><u> </u><u>logari</u><u>thmic</u><u> </u><u>form</u><u> </u><u>it</u><u> </u><u>is</u><u> </u><u>,</u><u> </u>

$\implies log_a^n = m$

Similarly our required answer will be ,

$\implies\boxed{ 10^a = 300 }$

Lillian is going to invest in an account paying an interest rate of 5.7% compounded continuously. How much would Lillian need to

Tems11 [23]

Answer: $5156

Step-by-step explanation:

Given

The rate of interest is 5.7%

time t=7 years

Amount after 7 years, $A=\$7600$

for compound interest, the Amount is given by

$\Rightarrow A=P(1+\frac{r}{100})^T$

Put values

$\Rightarrow 7600=P(1+0.057)^7\\\\\Rightarrow P=\dfrac{7600}{(1.057)^7}=5,155.71\\\\\Rightarrow P\approx \$5156$

Is y=2/3 x^2-7 linear or nonlinear

borishaifa [10]

Answer:

Nonlinear

Explanation:

y=2/3 x^2-7 is nonlinear because it is not in slope intercept form.

Also, x² automatically means it is nonlinear because this is the formula for a parabola when graphed. Parabolas are nonlinear.

The parabola also doesn't continue in a straight or nearly straight line. That is what linear is.
