Answer:
x=√65 and x=-√65
Step-by-step explanation:
Givn the expression 2x^2 - 9 = 121
Add 9 to both sides
2x^2 - 9 + 9 = 121 + 9
2x^2 = 130
Divide both sides b 2
2x^2/2 = 130/2
x^2 = 65
x = ±√65
x=√65 and x=-√65
This question is solved using range and domain concepts. Doing this, it is found that:
- The domain is: {-15, -4, 3, 25, 32}
- The range is: {-29, -10, 17, 21, 23}
--------------------------------------
- Domain: In a data-set, the domain is composed by the input values.
- Range: In a data-set, the range is composed by the output values.
--------------------------------------
- In a set of ordered pairs, the first term in a pair represents the input and the second represents the output.
- In this set, the inputs are: -4, 25, -15, 32, 3
- The outputs are: 23, 17, -29, 21, -10
Thus:
- The domain is: {-15, -4, 3, 25, 32}
- The range is: {-29, -10, 17, 21, 23}

That's a convoluted way to ask a simple question. 14.
I thought you said these problems were all different. They look exactly the same to me.
<span>Figure the volume of one of the small blocks, and use that to divide into the whole volume. </span>
<span>3 1/4 = 13/4 so the box has a volume of 13/4 * 3 * 1 = 39/4 ft^3 </span>
<span>each small block has a volume of (1/4)^3 = 1/64 ft^3 </span>
<span>(39/4) / (1/64) = 624
Hope this helps love.
