Answer:

  12 units

Step-by-step explanation:

Point B is the midpoint of AC, and it is 6 units from C. Therefore A must be 12 units from C.

  AC = 12 units

Kisachek [45]
For this case we have the following function:

 <span>f(w) = 1.1w

 </span>The first thing we must do for this case is to define the variables.
 <span />We have then:
 <span />w: represents watts
<span> 
 We observe that the function varies directly, therefore, we have a linear function and the constant of variation is positive.
 That is, the slope of the line is positive.
 Therefore, the linear function grows.

 Answer:
 B) light intensity increases linearly</span>

Circle D is shown. Line segments D E, D F, D G, and D H are radii. Angle E D F is 55 degrees, angle F D G is 70 degrees, and ang
aalyn [17]

Answer:

see the explanation

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the measure of arc EH

Remember that the measure of the complete circle is equal to 360 degrees

so

arc\ EH+arc\ EF+arc\ FG+arc\ GH=360^o

Remember that

arc\ EF=m\angle EDF ----> by central angle

arc\ FG=m\angle FDG ----> by central angle

arc\ GH=m\angle GDH ---> by central angle

substitute the given values

arc\ EH+55^o+70^o+110^o=360^o

arc\ EH=360^o-235^o=125^o

step 2

Which arc is congruent to Arc E H?

we know that

arc\ EFG=arc\ EF+arc\ FG=55^o+70^o=125^o

therefore

arc EH is congruent with arc EFG

or

arc EH is congruent with minor arc GE

A coin will be flipped repeatedly until the sequence TTH (tail/tail/head) comes up. Successive flips are independent, and the co
padilas [110]

Answer:

P = \frac{1}{3}

Step-by-step explanation:

The calculation of the value of p minimizes is shown below:-

We will assume the probability of coming heads be p

p(H) = p

p(T) = 1 - P

Now, H and T are only outcomes of flipping a coin

So,

P(TTH) = (1 - P) = (1 - P) (1 - P) P

= (1 + P^2 - 2 P) P

= P^3 - 2P^2 + P

In order to less N,TTH

we need to increase P(TTH)

The equation will be

\frac{d P(TTH)}{dP} = 0

3P^2 - 4P + 1 = 0

(3P - 1) (P - 1) = 0

P = 1 and 1 ÷ 3

For P(TTH) to be maximum

\frac{d^2 P(TTH)}{dP} < 0 for\ P\ critical\\\\\frac{d (3P^2 - 4P - 1)}{dP}

= 6P - 4

and

(6P - 4) is negative which is for

P = \frac{1}{3}

Adam can earn money recycling aluminium cans .each can weighs 15g and he can get paid 50p per kg . If Adam earns £15 , how many
kvasek [131]

there is 0.015 kilos in 15 grams. if each can weighs 0.015 and he gets paid 50p per KG. 0.015 X 66 will get you 1 kilogram! so you have 66 cans to get 1 kg worth of cans.  so there is 15 dollars and each kg is worth 50p- so 66 cans is = 50p

and there is 2 KG per dollar so 15 X 2 is 30! and then 66 X 30 is 1980!

66 for each KG and 30 represents how many 50p's are needed for 1 dollar!

so that is 1980 cans to get 15 dollars!
