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.

-x≥ -2

 multiply both sides by -1 ( to make x positive) and reverse the sign

x≤2

Solve for x. 5(x 1) = 4(x 8)
tresset_1 [31]
Asssuming blanks are plus

5(x+1)=4(x+8)

distribute
a(b+c)=ab+ac

5(x+1)=5x+5

4(x+8)=4x+32

5x+5=4x+32
minus 4x from both sides
x+5=32
minus 5 from both sides
x=27

Triangle ABC is similar to triangle QRS by the AA Similarity Postulate. Also, m∠A = 72° and m∠S = 56°. What is m∠B?
White raven [17]

∠B = 52°

Since the triangles are similar then

∠C = ∠S = 56°

∠B = 180° - (72 + 56)° = 52°

While I was jogging I was able to run 5 miles in 30 minutes from this information we can determine my?
Vikentia [17]
You can determine your speed that is Speed = (distance/Time). Mind you in this cast time should be in hour, so 30 min - 1/2 hour or 0.5 Hour

Your speed is 5/0.5 = 10 mi/hour
