24 x 10^4, the 4 comes from with how many jumps it took to land on a whole number from 240,000.

Answer:

4u^2-5u+7.

You just remove the parentheses because it's adding. If it were subtraction, you would need to distribute the minus.

Jan 10, 7:28:48 PM What is the slope of a line parallel to the line whose equation is 3x - 6y = 18. Fully reduce your answer.

marissa [1.9K]

Answer:

$1/2$

Step-by-step explanation:

We are given the line:

$3x-6y=18$

And we want to find the slope of the line parallel to this given line.

Remember that parallel lines have the same slope. So, if we can determine the slope of the given line, we have the slope of its parallel line.

To determine the slope of the given line, we simply have to isolate the y. So, we can first divide everything by 3. This yields:

$x-2y=6$

Adding 2y to both sides yields:

$x=6+2y$

And subtracting 6 from both sides yields:

$x-6=2y$

Finally, dividing everything by 2 gives us:

$\displaystyle y=\frac{1}{2}x-3$

Hence, the slope of our line is 1/2.

So, the slope of the line parallel to this line must also be 1/2.

Find the missing side of the angle. Need help,==== thank you!!

Pavel [41]

Answer: square root(265)

Step-by-step explanation:

Again, you can solve this via the Pythagorean theorem(a^2+b^2=c^2)

a= a side

b= another side

c= hypotenuse

Now, Substitute

12^2+11^2=x^2

144+121= 265

Now, square root and you get

square root(265)

Beginning drivers soon learn that bringing an automobile to a stop requires greater distances for higher speeds. A formula that

BaLLatris [955]

The formula for the stopping distance in feet is

$d=1.1v+0.055v^2$

where $v$ = Speed of the car in miles per hour.

The stopping distance for the car traveling at 15 mph is

$d=1.1\times 15+0.055\times 15^2\\\Rightarrow d=28.875\approx 29\ \text{feet}$

The stopping distance for the auto traveling at 15 mph is $29\ \text{feet}$ .

The stopping distance for the car traveling at 30 mph is

$d=1.1\times 30+0.055\times 30^2\\\Rightarrow d=82.5\approx 83\ \text{feet}$

The stopping distance for the auto traveling at 30 mph is $83\ \text{feet}$ .
