strojnjashka [21]

Answer: Voila

Step-by-step explanation:

26. equal opposite sides

27. Alla angles must equal 360 so 101+101=202 360-202=158/2=79

28. Intersecting equal sides

29. Opposite sides p=5 and since q-3=6 then q=9

30. Opposite equal angles 2m=70 so m=35 and n=110 because 360-140=220/2= 110

31. intersecting sides k+4=11 so k=7 and m=8

Find ( f o g) (x) when f (x) = x^2+6x+5 and g(x)=1/x+1

olchik [2.2K]

Answer:

$(f\circ g)(x)=\frac{1}{x^{2}}+\frac{8}{x}+12$

Step-by-step explanation:

Given that $f (x) = x^{2}+6x+5$ and $g(x)=\frac{1}{x}+1$ are the functions.

To find $(f\circ g)(x)$ with the given two functions. ie., to find the composite function of f(x) and g(x) which is denoted by $(f\circ g)(x)$

$(f\circ g)(x)=f(g(x))$

$=f(\frac{1}{x}+1)$

$=({\frac{1}{x}+1})^{2}+6\times ({\frac{1}{x}+1})+5$

$=\frac{1}{x^{2}}+\frac{2}{x}+1+\frac{6}{x}+6+5$

$=\frac{1}{x^{2}}+\frac{8}{x}+12$

Therefore $(f\circ g)(x)=\frac{1}{x^{2}}+\frac{8}{x}+12$

Therefore the composite function of f(x) and g(x) is $(f\circ g)(x)=\frac{1}{x^{2}}+\frac{8}{x}+12$

levacccp [35]

Answer:

B. 4/21

Step-by-step explanation:

⇒This question is on probability

⇒Number of boys=3

⇒Number of girls=4

⇒P(S)= 4+3=7

Probability for a girl to win is= 4/7

We have 3 awards a free movie ticket, a collectible poster, or a free popcorn

P(S)= 3

Probability of being awarded a free popcorn = 1/3

The probability that a girl will win free popcorn =

4/7 * 1/3 = 4/21

hope i helped and have a wonderful day

A high rise building has a sink on the fourth floor located 2-feet above the floor. Each floor is 10-feet above the other. Calcu

kap26 [50]

The pressure at a certain height is the pressure at sea level plus the hydrostatic pressure.

P = 80 psi + ΔP
where
ΔP = ρgh
ρ is the density of water equal to 62.4 lbm/ft³
ΔP = (62.4 lbm/ft³)(1 lbf/lbm)(4*10 + 2 ft)(1 ft/12 in)² = 18.2 psi

Thus,
P = 80 + 18.2
P = 98.2 psi
