If √7 = 2.646, find without using calculator, the value of √0.0007

Varvara68 [4.7K]

Answer:

√0.0007 = 0.02646

Step-by-step explanation:

We know that:

√7 = 2.646

We want to find the value of:

√0.0007

Also we know the relations:

$\frac{\sqrt{x} }{\sqrt{y} } = \sqrt{\frac{x}{y} }$

Then:

$\sqrt{0.0007} = \sqrt{\frac{7}{10,000} }$

We can rewrite this as:

$\sqrt{\frac{7}{10,000} } = \frac{\sqrt{7} }{\sqrt{10,000} } = \frac{2.646}{100} = 0.02646$

NEED HELP ASAP

algol [13]

Answer:

A) car one is linear because it decreases the same amount every year.

car two decreases by the same ratio so it's exponential.

B) for car one y = -6,000x + 38,000 (y is the value after x years, -6,000 is what it changes by every year, and 38,000 is the amount of year 0)

for car two y = (44,000) (17/20)x-1 (y is the value after x years, 44,000 is the amount on year 0, and 17/20 is the ratio)

C) after 5 years car one will be 8,000

after 5 years car two will be about 16,860
