Emma invested $41,000 in an account paying an interest rate of 2.6% compounded monthly. Assuming no deposits or withdrawals are

kvasek [131]

Answer: it will take 7 years for the value of the account to reach $49,300

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 = $41000

A = $49300

r = 2.6% = 2.6/100 = 0.026

n = 12 because it was compounded 12 times in a year.

Therefore,

49300 = 41000(1 + 0.026/12)^12 × t

49300/41000 = (1 + 0.0022)^12t

1.2024 = (1.0022)^12t

Taking log of both sides of the equation, it becomes

Log 1.2024 = 12t × log 1.0022

0.08 = 12 × 0.00095 = 0.0114t

t = 0.08/0.0114

t = 7 years

WILL GIVE THE BRAINLIEST. PLEASE HELP.

stiks02 [169]

Answer:

300 miles.

Step-by-step explanation:

Distance = Rate * Time

We know the rate, 80 miles per hour.

We know the time, 3.75 hours.

As these use the same time unit, hours, we don't need to change any values.

We can just put these values into the formula:

$d=r*t$

$d=80*3.75=300$

Answer: 300 miles.

I really need help with this question. Can I get a explanation too?

aniked [119]

Answer:

C

Step-by-step explanation:

Find the surface area:

Bottom base: 57 × 27 = 1,539

Top base: 21 × 27 = 567

Rectangular face: 23 × 27 = 621

Rectangular face: 23 × 27 = 621

Trapezoidal face: (21 + 57) ÷ 2 × 15 = 585

Trapezoidal face: (21 + 57) ÷ 2 × 15 = 585

1,539 + 567 + 621 + 621 + 585 + 585 = 4,518

The surface area is 4,518 square inches

What is the area in square feet of a triangle with a height of 4.5 and base of 6.6

Andrew [12]

Answer:

14.85

Step-by-step explanation:

The area of a triangle is given by

A = 1/2 bh where b is the base and h is the height

A =1/2 ( 6.6)(4.5)

A = 14.85

If f(x) =3^x+10 and g(x) =4x -2 find (f+g)(x)

Valentin [98]

Answer:

$(f+g)(x)=3^x+4x+8$

if $f(x)=3^x+10$ and $g(x)=4x-2$ .

Step-by-step explanation:

We are given $f(x)=3^x+10$ and $g(x)=4x-2$ .

We are asked to find $(f+g)(x)$ .

$(f+g)(x)$ means $f(x)+g(x)$

$(f+g)(x)=(3^x+10)+(4x-2)$

You only have one pair of like terms, that is the constants.

$(f+g)(x)=3^x+4x+10-2$

$(f+g)(x)=3^x+4x+8$
