Step-by-step explanation:

Answer: Step-by-step explanation: We are given an exponential equation.We need to convert it into it's equivalent equation.Let us factor 4.4 = 2 × 2Therefore, 2 × 2 could be written as .Now, let us factor 64 in terms of 2's.64 = 2 × 2× 2× 2× 2× 2 = .Replacing 4 by and 64 by in original equation, we get Distributing 2 over (x+3), we get

(a) What is wrong with the following equation? x2 + x − 42 x − 6 = x + 7 (x − 6)(x + 7) ≠ x2 + x − 42 The left-hand side is not

Answer:

Attached please find answer

Step-by-step explanation:

= (x² + x - 42) / (x - 6)

= [x² + (7x - 6x) - 42] / (x - 6)

= [x² + 7x - 6x - 42] / (x - 6)

= [(x² + 7x) - (6x + 42)] / (x - 6)

= [x(x + 7) - 6(x + 7)] / (x - 6)

= [(x + 7)(x - 6)] / (x - 6)

= x + 7 → when x approches 6

= 6 + 7

= 13

Other method:

Lim (x² + x - 42) / (x - 6)

x→ 6

When x → 6, there is an indeterminate expression because: 6 - 6 = 0

Do you know the l'Hôpital's rule, when x → a:

Lim [ f(x) / g(x) ] = Lim [ f'(x) / g'(x) ]

f(x) = x² + x - 42

f'(x) = 2x + 1

g(x) = x - 6

g'(x) = 1

= f'(x) / g'(x)

= (2x + 1)/1

= 2x + 1 → when x approches 6

= 12 + 1

= 13

PLEASE HELPPPPPPPPPPPPPPPP AREA AND CIRCUMFERENCE OF A CIRCLE

AnnyKZ [126]

Answer:

Area: 200.96 cm

Circumference: 50.24 cm

Explanation: I recently just learned this. The area of a circle is Pi times radius squared which makes. 3.14 x 8^2 = 3.14 x 64 = 200.96. SInce none of the original measurements are squared it will be 200.96 cm

The circumference of a circle is diameter times pi which makes 3.14 x (8 x 2) = 3.14 x 16 = 50.24. Since none of the original measurements are squared it will be 50.24 cm

I hope this helps! pls mark brainliest if it helps!

DIA [1.3K]

Answer:

The sub rose 121 feet.

Step-by-step explanation:

The sub was less deep at 12 pm than at 10 am, so rose in the water. The amount it rose was ...

410 -289 = 121 . . . . feet

If you like, you can think of the sub's elevation relative to the surface as changing from -410 feet to -289 feet. The difference is then an increase in elevation (rise) of ...

-289 -(-410) = -289 +410 = 121 . . . feet

_____

12 am is midnight, 14 hours after 10 am. The time 2 hours after 10 am is 12 pm, noon.
