Find the measurements of

Answers

Answer 1

Answer:

For x -

180 = 4x + 6 + 11x - 6

180 = 15x

$(180)/(15)$ = x

x = 12

For m∠ABD -

4(12) + 6

48 + 6

m∠ABD = 54

For m∠DBC -

11(12) - 6

132 - 6

m∠DBC = 126

Answer 2

Answer:

Answer:

x = 12° ;m∠ABD= 54° ; m∠DBC=126°

Step-by-step explanation:

∠ABD + ∠DBC = ∠ABC

Here ,

∠ABC is a straight line .

We know,

A straight angle is 180 degrees.

So,

∠ABD + ∠DBC = 180°

⇒(4x+6)° + (11x-6)° =180° [given]

⇒15x =180°

⇒x = (180/15)° [divide both sides by 15]

∴ x = 12°

Now,

∠ABD = (4x+6)° [given]

={(4 . 12) + 6 }°

=(48+6)°

=54°

And,

∠DBC = (11x-6)° [given]

={(11 .12)-6}°

=(132 - 6)°

=126°

bactena population doubles n sze every 5 hours. After 5 hours, the sample contains 2,000 bacteria Which equation best models y. the population size after x hours?

Answers

Answer:

$Y=1000*2^(x)$

Step-by-step explanation:

It is given that A bacteria population doubles in size every 5 hours. After 5 hours, the sample contains 2,000 bacteria.

and also Y=populations size and x=number of hours.

so at x=0 , Y=1000 and after 5 hours x=5 ,Y=2000. and after 5 more hours

at x=10, Y=4000

so we see that it is doubling every 5 hours i.e. the Equation will be like this

$Y=1000*2^(x)$

where x= multiple of 5 years.

If a sequence is defined recursively by f(0) = 2 andf(n +1) = -2f(n) + 3 for n ≥ 0, then f(2) is equal to

Answers

If you would like to know how much is f(2), you can calculate this using the following steps:

f(0) = 2
f(n+1) = - 2 * f(n) + 3
f(1) = - 2 * f(0) + 3 = - 2 * 2 + 3 = - 4 + 3 = - 1
f(2) = - 2 * f(1) + 3 = - 2 * (-1) + 3 = 2 + 3 = 5

The correct result would be f(2) = 5.
