Recall that with base-ten blocks: 1 long equals=10 units, 1 flat equals=10 longs, and 1block equals=10 flats. What is the fewest number of multibase blocks that can be used to represent the corresponding numeral in the given base?

a. 20 longs in base seven
b. 10 longs in base three

Explain why the function is discontinuous at the given number a. (select all that apply.) f(x) = 1 x + 1 a = −1 f(−1) is undefined. lim x→−1+ f(x) and lim x→−1− f(x) exist, but are not equal. lim x→−1 f(x) does not exist. f(−1) and lim x→−1 f(x) exist, but are not equal. none of the above

Suppose a pendulum is l meters long. the time,t,in seconds that it tales to swing back and forth once is given by t=2.01

Find the zeros of each function. f(x) = 6x^2 - 7x - 20
