Answer:
<h2>The required time is 8 years.</h2>
Step-by-step explanation:
Let, it will take x years to be of same height for these trees.
We know that 1 ft = 12 inches.
8 ft = . 2 ft = 24 inch.
After x years, the height of type A will be (96 + 6x) inch and the height of type B will be (24 + 15x) inch.
We need find the value of x, for which 96 + 6x = 24 + 15x or, 9x = 72 or, x = 8.
Answer:
B. 230
Step-by-step explanation:
The formula is 2(wl+hl+hw).
Use this formula for every rectangular prism.
Density = mass / volume.
Volume = Final reading - Initial reading = 7 - 2 = 5 cm^3
Hence,
D = 25 / 5 = 5 g/cm^3
<span>Remember, cubic centimeters is a volume unit (the same volume as 1 milliliter)</span>

Solution: x ≥ -5
<h2>Steps</h2>
Domain Definition: The domain of a function is the set of input or argument values for which the function is real and defined
<u>squareroot 2x + 10</u> ⇒ <u>2x + 10 ≥ 0</u>
Solve 2x + 10 ≥ 0:
Subtract 10 from both sides
2x + 10 - 10 ≥ 0 - 10
Simplify
2x ≥ -10
Divide both sides by 2
2x / 2 ≥ -10 / 2
Simplify
2x / 2
Divide the numbers: <u>2 / 2 = 1</u>
= x
Note: x has the same value as 1
Divide the numbers: -10 / 2 = -5
= -5
The function domain is
x ≥ -5
Y=X(K)
9=2(K)
9/2=4.5
K=4.5
Answer is 4.5
