Suppose you invest $7500 at an annual interest rate of 4.2% compounded continuously. How much will you have in the account after

tatyana61 [14]

<span>Interest=principle x rate x time (in years)
so putting values so
Interest=7500 (.042)(2)
so
Interest=630 7500+630=8130
Interest=500 (.071)(4)
Interest=142 500+142=64

7,,,,,,,,,,,,,,,,,,,,please help

Goryan [66]

Answer:

Step-by-step explanation:

The given expression is

$\frac{2^{\frac{11}{2} }\times 2^{-7}\times 2^{-5}}{2^3\times 2^{\frac{1}{2} }\times 2^{-10}}$

Recall and use

$a^m\times a^n=a^{m+n}$

$\frac{2^{\frac{11}{2} -7-5}}{ 2^{3+\frac{1}{2} -10}}$

$\frac{2^{-\frac{13}{2}}}{ 2^{-\frac{13}{2}}}$

Same bases are dividing, so we write one base and subtract the exponent.

$2^{-\frac{13}{2}+\frac{13}{2}}$

$2^0=1$

Write the expression below as a single logarithm in simplest form.<br> logo 7 – log, 7

Svet_ta [14]

Given:

The given expression is:

$\log_b7-\log_b7$

To find:

The single logarithm expression for the given expression.

Solution:

Quotient property of logarithm:

$\log_bm-\log_bn=\log_b\left(\dfrac{m}{n}\right)$

We have,

$\log_b7-\log_b7$

Using quotient property of logarithm, we get

$\log_b7-\log_b7=\log_b\left(\dfrac{7}{7}\right)$

$\log_b7-\log_b7=\log_b\left(1\right)$

Therefore, the required expression is $\log_b\left(1\right)$ .
