Answer:

D. -5 <= x < 1

Step-by-step explanation:

the values under the square-root radical must not be negative, AND

the value of the denominator must not be 0 or negative

x+5 >=0 or x >= -5

and 1-x > 0 or x < 1

So the answer is -5 <= x < 1

Nina [5.8K]

Answer: 4 years after the original investment, it is approximately $1,093.

Step-by-step explanation:

Hi, to answer this question we have to apply the simple interest formula:

I = p x r x t

Where:

I = interest

P = Principal Amount

r = Interest Rate (decimal form)

t= years

Replacing with the values given

I = 1000x (2.25/100) x t

It will triple in approximately 3 years. FALSE

I = 1000x (2.25/100) x 3 =67.5

1000+67.5 = 1067.5

It will no longer grow after several years: False, it will grow because it has a growth rate.

4 years after the original investment, it is approximately $1,093. TRUE

I = 1000x (2.25/100) x 4 =90

1000+90 = $1090

It will double in approximately 10 years.

I = 1000x (2.25/100) x 10 =225

1000+90 = $1225

How tall is the tower?

Karo-lina-s [1.5K]

Answer:

93.6 ft

Step-by-step explanation:

$\bf \cfrac{AB}{BC} = \tan(60)$

$\bf \cfrac{x}{50} = \sqrt{50}$
$\bf x = 50 \sqrt{3}$

Length of tower:-

$\bf x + 7$
$\bf 50 \sqrt{3} + 7$
$\bf 93.6025$
$\bf = 93.6$

Therefore, the tower is 93.6ft tall.
