A rectangular garden is fenced on all sides with 258 feet of fencing. The garden is 7 feet

Bumek [7]

Answer:

L = w + 8

P = 2L + 2w

256 = 2 (ancho + 8) + 2w

256 = 2 vías + 16 + 2 vías

256 = 4 semanas + 16

240 = 4w

w = 60

La longitud es 60 + 8 = 68

el ancho es 60

find h and k such that the equation 3x^2 -hx +4k =0, so that the sum of the solutions is -12 and the product of the solutions is

Radda [10]

Let the solutions be a and b.
a = -2; b = -10
a + b = -2 + (-10) = -12
ab = (-2)(-10) = 20

(x - a)(x - b) = 0

(x - (-2))(x - (-10)) = 0

(x + 2)(x + 10) = 0

x^2 + 10x + 2x + 20 = 0

x^2 + 12x + 20 = 0

-h = 12

h = -12

4k = 20

k = 5

<h3>What is compound interest?</h3>

Compound interest is the interest levied on the interest. The formula for the calculation of compound interest is given as:-

$A=P[1+\dfrac{r}{n}]^{nt}$

a) The amount in the bank after 6 years if interest is compounded annually.

$A=P[1+\dfrac{r}{1}]^{t}\\\\\\A=6000[1+\dfrac{0.01}{1}]^{ 6}$

A= $6369

b) The amount in the bank after 6 years if interest is compounded quarterly.

$A=P[1+\dfrac{r}{4}]^{4t}\\\\\\A=6000[1+\dfrac{0.01}{4}]^{4\times 6}$

A= $6090

c ) The amount in the bank after 6 years if interest is compounded monthly.

$A=P[1+\dfrac{r}{12}]^{4t}\\\\\\A=6000[1+\dfrac{0.01}{12}]^{12\times 6}$

A=$6030

Hence the amount for the investment of $6000 will be a.$6369 b. $6090 and c.$6030.
