Answer:
4/5
Step-by-step explanation:
The equation for the given sequence representing the diameter of the circle is
f(n) = f(n-1) + 0.6, where f(1) = 2.5
Given, a sequence of diameters of a circle used to create an art project
2.5 , 3.1 , 3.7 , 4.3
We have to find a sequence that represents the diameter of the given circle,
Let f(n) be representing the diameter of the circle,
Now, for n = 1
f(n) = 2.5
for n = 2
f(n) = 3.1
for n = 3
f(n) = 3.7
for n = 4
f(n) = 4.3
As, f(2) = f(1) + 0.6 and so,
So, f(n) = f(n-1) + 0.6
Hence, the equation for the given sequence representing the diameter of the circle is
f(n) = f(n-1) + 0.6, where f(1) = 2.5

Hey there! I'm happy to help!
We want to figure out what x is. Let's use a trigonometric ratio of our 35 degree angle to find it.
We see that x is opposite of the 35 degree angle. We also see that our hypotenuse 4.1 m. The hypotenuse is always across from the right angle.
The trigonometric ratio that deals with opposite and hypotenuse is the sine, which is the opposite divided by the hypotenuse. This gives us the following equation.
We want to solve for x, so we simply multiply both sides 4.1
If we evaluate this on our calculators, we get 2.351663389......
We round this to the nearest tenth, giving us 2.4 m.
Have a wonderful day! :D
Let x represent the length of the shortest side. Then the perimeter is
.. x +2x +(x +13) = 149
.. 4x = 136
.. x = 34
2x = 68
x+13 = 47
The lengths of the sides are 34, 47, and 68 ft.
Answer:
a. 5 hours
b. 40 kph
Step-by-step explanation:
300 km ÷ 60 km = 5 hours
200 km ÷ 5 hours = 40 kilometers per hour
