Delilah deposits 8,255 in an account that pays 4.2% simple interest. How much money will be in her account after 8 years
lara31 [8.8K]

Answer:

11235.35

Step-by-step explanation:

Given data

P=8225

R=4.2%=0.042

T=8years

The simple interest formula is

A=P(1+rt)

Substitute

A=8225(1+0.042*8)

A=8225(1+0.336)

A=8225*1.366

A=11235.35

Hence the balance will be 11235.35

TRIANGLE ABC IS DILATED BY A SCALE FACTOR OF 0.5 WITH THE ORIGIN AS THE CENTER OF DILATION, RESULTING IN THE IMAGE TRIANGLE A'B'
const2013 [10]

Answer: The length of the line B'C" is 1 unit.

Step-by-step explanation:

Given: Triangle ABC is dilated by a scale factor of 0.5 with the origin as the center of dilation , resulting in the image Triangle A'B'C'.

If A (2,2), B= (4,3) and C=(6,3).

Distance between (a,b) and (c,d): D=\sqrt{(d-b)^2+(c-b)^2}

Then, BC =\sqrt{(3-3)^2+(6-4)^2}

\\\\=\sqrt{0+2^2}\\\\=\sqrt{4}\\\\=2\text{ units}

Length of image = scale factor x length in original figure

B'C' = 0.5 × BC

= 0.5 × 2

= 1 unit

Hence, the length of the line B'C" is 1 unit.
