Step-by-step explanation:
I hope I'm correct. I've never learnt differentiation for log and exponents before
Answer:
Step-by-step explanation:
2. 24^2+7^2 = 625
V 625 = 25
3. 6^2 + 5^2 = 25 +36 = 61
V 61 =7.81024967 =7.8
4. 4^2 +9^2 = 97
V 97= 9.84885780 = 9.8
5. 2^2 +3^2 = 13
V 13 =3.60555127 =3.6
and done!
(x) = 95x + 25 is correct, since the $25 cost is fixed, but the $95 cost increases as x increases.
Answer:
<h2>1. t=2m</h2>
Rewrite the equation as 2m=t.
2m=t
Divide each term by 2 and simplify.
m=t/2
<h2>2. y=2x+1</h2>
Isolate the variable by dividing each side by factors that don't contain the variable.
x=y/2−1/2

Answer:
<u>13 - 2x </u>
Step-by-step explanation:
(x +2)² + (x - 3)² - 2x²
<em>Expand.</em>
(x + 2)(x + 2) + (x - 3)(x - 3) - 2x²
x² + 2x + 2x + 4 + x² - 3x - 3x + 9 - 2x²
<em>Bring all the like terms together then simply.</em>
x² + x² - 2x² + 2x + 2x - 3x - 3x + 4 + 9
2x² - 2x² + 4x - 6x + 13
= <u>13 - 2x</u> (or <u>-2x + 13</u> )
