The following statement is false. rewrite the statement to make it true. the sum of the infinite series 3 + 4 + 5 + 6 + … is infinity ∞ . (this symbol is infinity.)

solution:

true,

we haveben asked to check that wheather the given option is true or false.

3 + 4 + 5 + 6 + … is   ∞

as we can see the series is an atrithmetic series.

and we know that the sum of n terms of an arithemtic   series with first erm

is given by the formula

now if we take the value of n is not defined i.e   ∞ then the sum will be undefined i.e   ∞. hence the statement is true.

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

step-by-step explanation:

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
