What numbers must be added to complete the perfect square?

Evgen [1.6K]

Answer:

256

Step-by-step explanation:

Let the number be k

Thus, the equation can be written as:

x² – 32x + k

From the above,

a = 1

b = –32

c = k

The value of k can be obtained as follow:

b² = 4ac

(–32)² = 4 × 1 × k

1024 = 4k

Divide both side by 4

k = 1024 / 4

k = 256

Thus, 256 should be added to x² – 32x to make it a perfect square i.e

x² – 32x + 256

****Check****

x² – 32x + k

k = 256

x² – 32x + 256

x² – 16x – 16x + 256

x(x – 16) – 16(x – 16)

(x – 16)(x – 16)

(x – 16)² QED

Calvin deposits $400 in a savings account that accrues 5% interest compounded monthly. after c years, calvin has $658.80. makayl

Answer:

The approximate difference in time is 2 years.

Step-by-step explanation:

The equation for Calvin's account is

$658.80=400(1+\frac{0.05}{12})^{12c}$

To solve for c, we first divide both sides by 400. This gives us:

$1.647=(1+\frac{0.05}{12})^{12c}$

Using logarithms to solve this, we have

$\log_{1+\frac{0.05}{12}}1.647=12c\\\\119.9986131=12c$

Dividing both sides by 12, we get c = 9.9998 or around 10 years.

The equation for Makayla's account is

$613.04=300(1+\frac{0.06}{4})^{4m}$

Dividing both sides by 300, we get

$2.043466667=(1+\frac{0.06}{4})^{4m}$

Using logarithms to solve this, we have

$\log_{1+\frac{0.06}{4}}2.043466667=4m\\\\4m=47.9961799$

Dividing both sides by 4, we get

m = 11.9999 or about 12.

This means Makayla had her money in the account 12-10 = 2 years longer than Calvin.
