My name is Ann [436]

Switch sides

4/5 (x+3)=y+6

Multiply both sides by 5

5*4/5 (x+3) = 5y+5*6

Simplify

4(x+3) = 57+30

Divide both sides by 4

4(x+3)/4 = 5y/4+ 30/4

Simplify

x+3 = 5y+30/4

Subtract 3 from both sides

x+3 - 3 = 5y+30/4 - 3

Simplify

x=5y+30/4 - 3

Sarah invested $1000 in an account paying 5.5% interest compounded semi-annually. How long will it take for the account balance

NISA [10]

Answer: it will take 43.25 years

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1+r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

P = $1000

A = $10450

r = 5.5% = 5.5/100 = 0.055

n = 2 because it was compounded 2 times in a year.

Therefore,.

10450 = 1000(1 + 0.055/2)^2 × t

10450/1000 = (1 + 0.0275)^2t

10.45 = (1.0275)^2t

Taking log of both sides, it becomes

Log 10.45 = 2t log 1.0275

1.019 = 2t × 0.01178 = 0.02356t

t = 1.019/0.02356

t = 43.25 years

HELP! Write the logarithmic equation in exponential form!

Schach [20]

Answer:

We conclude the exponential form will be:

$729\:=\:\:9^3\:$

Step-by-step explanation:

Given the logarithmic equation

$3=\log _9\left(729\right)$

Writing the logarithmic equation in exponential form.

We know that

$\:\log _a\left(b\right)=x\:$ → $\:\:a^x=b$

Let us write the logarithmic equation in exponential form using the expression above

a = 9

b = 729

x = 3

Thus, we conclude the exponential form will be:

$729\:=\:\:9^3\:$
