How do you write 1.5 × 104 in standard form?
rewona [7]
I'm assuming you meant 1.5 × 10⁴. Remember, when we write in standard form, you need to use ^ to denote it's 'to the power of'. So it would be 1.5 × 10^4. 

I'm also assuming you meant in decimal form, because that's already in standard form.

However, the answer is 15,000. This is because you lose one zero when multiplying a decimal with one number after it. For each number after the decimal, you take off a zero. Therefore, the end number is 15,000.

<h3>Exact Answer: (160/3)pi</h3><h3>Approximate Answer: 167.47</h3>

The approximate answer results when you use pi = 3.14, and this approximate answer is rounded to two decimal places

note that (160/3)pi is the same as 160pi/3

========================================================

Work Shown:

r = radius = 4

h = height = 10

V = volume of cone

V = (1/3)pi*r^2*h

V = (1/3)pi*4^2*10

V = (160/3)pi exact answer

V = (160/3)*3.14

V = 167.46666....

V = 167.47 approximate answer rounded to two decimal places

Find the values of x and y in the following equation.<br><br> (X+Yi)+(4+9i)=9-4i
guajiro [1.7K]
<span>(X+Yi)+(4+9i)=9-4i

The first step is removing the parenthesis:

X + Yi +4 + 9i = 9-4i 
</span><span>
No lets separate the like terms on both sides:

x +4 = 9
Yi +9i = -4i

We can now solve for X:  
x +4 = 9
Subtract 4 from each side:
x = 9-4
x = 5

Yi+9i = -4i

Subtract 9i from each side:
Yi = -4i-9i
Yi = -13i
Y = -13

X = 5, Y = -13.
