Answer:

It will take 14.29 years for your bank balance to double from $1,000 to $2,000.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E are the earnings, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

T = E + P.

If the interest rate is 7%, how many years will it take for your bank balance to double from $1,000 to $2,000?

We have that P = 1000, I = 0.07

We want to find t when E = 1000, so T = P + E = 2000.

E = P*I*t

1000 = 1000*0.07*t

t = \frac{1}{0.07}

t = 14.29

It will take 14.29 years for your bank balance to double from $1,000 to $2,000.

The roots of a quadratic equation ax2+bx+c=0 are 3+sqrt2 and 3−sqrt2. Find the values of b and c assuming that a=1.
slamgirl [31]

Answer:

b=-6\\c=7

Step-by-step explanation:

we know that

The general equation of a quadratic function in factored form is equal to

y=a(x-x_1)(x-x_2)

where

a is a coefficient of the leading term

x_1 and x_2 are the roots

we have

a=1\\x_1=3+\sqrt{2}\\x_2=3-\sqrt{2}

substitute

y=(1)(x-(3+\sqrt{2}))(x-(3-\sqrt{2}))

Applying the distributive property convert to expanded form

y=x^2-x(3-\sqrt{2})-x(3+\sqrt{2})+(3+\sqrt{2})(3-\sqrt{2})

y=x^2-(3x-x\sqrt{2})-(3x+x\sqrt{2})+(9-2)

y=x^2-3x+x\sqrt{2}-3x-x\sqrt{2}+7

y=x^2-6x+7

therefore

b=-6\\c=7

neonofarm [45]

Correct answer is B. Begin it with the words "Antarctica is".

<h3>what is Antarctica? </h3>

Antarctica The least inhabited and most southern continent on Earth is. It encompasses the geographical South Pole and is almost fully south of the Antarctic Circle, bordered by the Southern Ocean. With a surface area of 14,200,000 km2, Antarctica is the fifth-largest continent, being nearly twice the size of Australia and larger than Europe (5,500,000 sq mi). Ice blankets the majority of Antarctica, with an average thickness of 1.9 km (1.2 mi).

The continent with the greatest average elevation is Antarctica, which also tends to be the coldest, driest, and windiest overall. With around 200 mm (8 in) of yearly precipitation at the shore and much less inland, it is primarily a polar desert.

mars1129 [50]

Answer:

Option A 95\ ft

Step-by-step explanation:

we know that

1\ ft=12\ in

The height of the player is 6\ ft\ +4\ in

6\ ft\ +4\ in=6*12+4=76\ in  

so

by proportion

\frac{4}{5} \frac{in}{ft}=\frac{76}{x}\frac{in}{ft}\\ \\x=5*76/4\\ \\x=95\ ft
