Answer: 1. 210 meters per second .

2. 756 kilometers per hour.

Step-by-step explanation:

Given : The formula $S(d)=\sqrt{9.8d}$ to calculate the estimated speed, in meters per second of a tsunami.

1. If the disturbance occurred at an ocean depth of 4,500 meters.

Then put d= 4500 in the above formula , we get

$S(d)=\sqrt{9.8\times4500}$

$S(d)=\sqrt{44100}=\sqrt{21\times21\times10\times10}\\\\=\sqrt{210^2}=210$

Hence, if the disturbance occurred at an ocean depth of 4,500 meters , the estimated speed would be 210 meters per second .

Also, A meter per second is equal to 3.6 kilometers per hour.

i.e. 1 meter per second = 3.6 kilometers per hour

Then by unitary method ,

210 meters per second = $3.6\times210$ kilometers per hour

=756 kilometers per hour.

Factor completely -2x^3 + 6x^2

Bumek [7]

We can factor a -2 and an x^2 out of this using GCF.

<h3>-2x^2(x - 3) is what we're left with, and is the fully factored form.</h3>

Answer:

The correct option is A.

Step-by-step explanation:

The given number is

$\frac{5}{11}$

Where 5 is dividend and 11 is divisor.

Since dividend is less than divisor we add a decimal place and the first zero. Notice the decimal point which has appeared on the answer line and by the dividend. It does not appear anywhere else.

Now the dividend is 50. Divide the number by divisor.

$11\times 4=44$

Subtract 44 from 50.

$50-44=6$

Therefore remainder is 6. Place a zero after 6.

Now the new dividend is 60. Divide the number by divisor.

$11\times 5=55$

Subtract 55 from 60.

$60-55=5$

Therefore remainder is 5.

$\frac{5}{11}=0.454545$

$\frac{5}{11}\approx 0.45$

Therefore option A is correct.

Need help on number 1, 5 and 7

zimovet [89]

Answer:

1) y = (x + 8)² + 7; 5) y = (x - 6)² + 10; 7) y = (x - 3)² - 4

Step-by-step explanation:

Complete the square in order to figure these out. To complete the square, use the formula [½B]². Each time you do this, you get a perfect trinomial in the form of a product of two monomials [h], then you have to figure out how much more to deduct from or add on to your C they gave you in each exercise [k].
