6.0⋅<span>102</span><span>kg m<span>−3</span></span>
Explanation:
In order to find the density of the bowling ball, <span>ρ
</span>, you must determine the mass one unit of volume of this bowling ball would have.
Notice that the problem provides you with the volume of the bowling ball expressed cubic meters, <span><span>m3</span>
</span>, which means that one unit of volume would be <span><span>1 m3</span>
</span>.
Now, you know that a volume of <span><span>0.0050 m3</span>
</span> has a mass of <span>3.0 kg
</span>. You can use this known proportion as a conversion factor to figure the mass of <span><span>1 m3</span>
</span>
<span><span>1<span>m3</span>⋅<span>3.0 kg<span>0.0050<span>m3</span></span></span>=600 kg</span>
</span>
So, you know that one unit of volume has a mass of <span>600 kg
</span>, which means that the bowling ball's density is equal to
<span><span><span>ρ=6.0⋅<span>102</span><span>kg m<span>−3</span></span></span><span>−−−−−−−−−−−−−−−−−</span></span>

The answer is rounded to two sig figs.
Answer: Domain (-∞,∞) ; range: (0,∞)
Step-by-step explanation:
1. The exponential functions with the form 
has domain of all real numbers, becaure there is no values in the set of real number for which the value of 
is not define. When approches to ∞, the function approches to ∞.
2. When approches to -∞, the function approches to 0 but never touches it. This means that 
is always greater than zero (
). Therefore, the range of the function is (0,∞).
Answer:
a=7
Step-by-step explanation:
Given,
6a-7=3a+14
or,6a-3a=14+7
or,3a=21
or,a=7 [ANSWER]
Answer:
$343
Step-by-step explanation:
To get 30% of 490 we divide 30% by 1
30% ÷ 1 = 147
Now, we subtract 490 by 147
490 - 147 = 343
Answer:
To find a number's square root, determine which two perfect squares the number lies between and estimate a fraction between those two perfect square roots. If it is a perfect square itself the square root can be arrived at precisely. If not, divide the number by one of the two closest square roots and average the result with the root. So there really isn't any answer to accurately do this that i'm aware of hope this helped!
