Answer:
x=r/6
Step-by-step explanation:
Answer: 14,899
<u>Step-by-step explanation:</u>
P = 2500 e°⁰³⁵ˣ
t = 2039 - 1988
= 51
P = 2500 e°⁰³⁵⁽⁵¹⁾
= 2500 e¹°⁷⁸⁵
= 2500 (5.9596)
= 14,898.94
rounded to the nearest whole number: P = 14,899
Answer:
2 works
-3 is extraneous
Step-by-step explanation:
sqrt(x + 7) - 1 = x Add 1 to both sides
sqrt(x + 7) = x + 1 Square both sides
(x + 7) = (x + 1 )^2
x + 7 = x^2 + 2x + 1 Subtract x from both sides
0 = x^2 + x + 1 -7
0 = x^2 + x - 6 This will factor
(x + 3)(x - 2) = 0 Find the values for x
x + 3 = 0
x = - 3
x - 2 = 0
x = 2
Now you must check this to see if both values work
sqrt(-3 + 7) - 1 = -3
sqrt(4) - 1 = -3
2 - 1 =? - 3
1 does not equal - 3. Therefore - 3 is extraneous. Try x = 2
sqrt(2 + 7) - 1 = 2
sqrt(9) - 1 = 2
3 - 1 = 2
2 = 2
ANSWER
The irrational numbers are
and
EXPLANATION
The irrational numbers are the square root of the non perfect squares.
In oder words, the irrational numbers are the ones, whose square root are not exact.
So we must first simplify the radicals and choose the ones whose values are not exact.
This is an exact value, so it is rational.
This is irrational because the radicand, 2, is a non perfect square.
is also irrational because 10 is a non perfect square.
is also irrational because 15 is a non perfect square.
is rational because 36 is a perfect square.
The surface area of a shape is the amount of space on the shape
When the dimensions are quadrupled, the new surface area would be 16 times the initial surface area
<h3>How to determine the surface area</h3>
The surface area of a rectangular prism is:
When quadrupled, we have:
Factor out 16
Substitute
The above means that:
The new surface area would be 16 times the initial surface area
