Let f(x) = x2 + 6 and g(x)= x+8/x . Find ( g o f)( -7)

1 answer:

7 0

(g o f)(x)=g(f(x))
so

(g o f)(-7)=g(f(-7))=
g((-7)^2+6)=
g(49+6)=
g(55)=
55+8/55=
55 ad 8/55

(g o f)(-7)=55 and 8/55
(if you meant g(x)=(x+8)/x, then the result is 63/55 or 1 and 8/55)

A 5-meter ladder is leaning against the side of a house. The foot of the ladder is pulled away from the house at a rate of 0.4 m

Flura [38]

<h2>The top of the ladder is descending at 0.3 m/s.</h2>

Step-by-step explanation:

By Pythagoras theorem we know that

Hypotenuse² = Base² + Perpendicular²

h² = b² + p²

We have for ladder

h = 5 m

b = 3 m

5² = 3² + p²

p = 4 m

$\frac{db}{dt}=0.4m/s\\\\\frac{dh}{dt}=0$

Differentiating h² = b² + p² with respect to time

$2h\times \frac{dh}{dt}=2b\times \frac{db}{dt}+2p\times \frac{dp}{dt}\\\\5\times 0=3\times 0.4+4\times \frac{dp}{dt}\\\\\frac{dp}{dt}=-0.3m/s$

The top of the ladder is descending at 0.3 m/s.

Please please i need help i will mark u brill

zvonat [6]

Answer:

106 - 8h = 34

Whenever a math question says "when <em>h </em>= 9," they mean you substitute this number where <em>h </em>is in the equation.

106 - 8(9) = 34

106 - 72 = 34

34 = 34

This means the fact that h = 9 <u>is a solution for h.</u>

HELP PLEASE! The probability of drawing a penny from a bag of coins is 1/5. What is the probability of drawing a coin that is no

lutik1710 [3]

Okay so since with the penny it's 1/5 that means there's only one penny and 5 other coins and 100% is 5 then 80% will be 4 so your answer is 80% hope this helps
