Given that: a = 2, b = -4

\sqrt{a^3-7}\text{ + |b| = }\sqrt{2^3-7}\text{ + |-4| = }\sqrt{8-7}\text{ }+\text{ 4 = }\sqrt{1}+\text{ 4 = 1 + 4 = 5}

Answer:

110.4622 = 110 (as followers cannot be in decimals).

Step-by-step explanation:

Given, growth rate is 1% = 0.01.

and it is for every 12 hours.

now, f(x) = f(1 + r)^t. where f= 100 (initial followers)

                            r = 0.01.

                             t =10 (1 for every 12 hours. so, 5 days = 120 hours = 10 times)

⇒ f(x) = 100(1+0.01)¹⁰ = 110.4622 = 110 followers.

irina1246 [14]

Answer:

19.5

Step-by-step explanation:

Here is a key factors in triangles, it must add up to 180 degrees.

You have three angles in a triangle ABC,

A = 127

B = 33.5

C = ?

In this case you would add the two together (160.5) and subtract from 180 giving you the angle C = 19.5

CHECK:

Add 127+33.5+19.5 = 180! Yes!

PLs mark brainliest if you can! :)
