Tanzania [10]

Answer: y = 1 +/- $\sqrt{x+5}$

<u>Step-by-step explanation:</u>

y² - 2y + 1 = x + 5

(y - 1)² = x + 5

$\sqrt{(y-1)^{2}} = \sqrt{x+5}$

y - 1 = +/- $\sqrt{x+5}$

y = 1 +/- $\sqrt{x+5}$

leonid [27]

Answer:

$1.80

Step-by-step explanation:

Use formula

$I=P\cdot i\cdot t,$

where I is interest, P is total principal, i is rate of interest per year (as decimal) and t is total time in years.

In your case,

I=$36.45, t=312, i=0.065, then

$36.45=P\cdot 0.065\cdot 312,\\ \\P\approx \$1.80$

nydimaria [60]

Answer:

A. 112 m^2

Step-by-step explanation:

If the scale factor is 4, the area of the larger figure is 4^2 times that of the smaller one.

... (7 m^2)·4^2 = 112 m^2

_____

The scale factor for area is the square of the scale factor for linear dimensions. When we talk about a scale factor without qualification, we mean the scale factor for linear dimensions.
