Step-by-step explanation:

the third of 7 consecutive numbers is 12.

so, this looks like

..., ..., 12, ..., ..., ..., ...

that means the numbers have to be

10, 11, 12, 13, 14, 15, 16

the sum is then

16+10 + 15+11 + 14+12 + 13 = 3×26 + 13 = 91

I am Lyosha [343]

15 500 at 11% ordinary interest for 120 days.
=> 120 days = approximately 4 months.
=> 15 500 * .11 = 1705 dollars interest
=> 15 500 + 1750 = 17 205 dollars
=> 17 205 dollars - 3000 dollars after 70 days = 14 205 dollars is the amount due

Match each function with the corresponding function formula when h(x) = 2 – 2x and g(x) = –2 x + 2.

Minchanka [31]

the correct functions are

h(x) = 3x + 2

g(x) = 2^x

proceed to calculate the different values of K (x)

case 1) k(x) = g(x) ∘ h(x)

g(x) ∘ h(x)=g(h(x))

k(x) = [2]^[3x + 2]-----------> is the option 4. k(x) = 2^(3x + 2 )

case 2) k(x) = g(x) + h(x)

k(x) = [2^x]+[3x + 2]=2^x+3x+2--------> is the option 1.) k(x) = 2^x + 3x + 4

case 3)k(x) = g(x) - h(x)

k(x) = [2^x]-[3x + 2]=2^x-3x-2--------> is the option 2.) k(x) = 2^x - 3x - 2

What the answer now to the question

Lostsunrise [7]

Step-by-step explanation:

Hello!!!

Given, VXW is a Right angled triangle where WV =4 and XV =5.

now, by taking reference angle as angle W, and using tangent we get;

p=5

b=4

again, 

tan thita =p/b

tan thita = 5/4

so, tan thita =1.25.

now, to find angle W, we should do tan thita inverse;

or, (tan thita)-1= tan thita-1(1.25)

or, (tan thita) -1 =51.3401°.

Now, by rounding off we get,

tan thita (angle W )= 51°.

Hope it helps....
