the 3rd term of an arithmetic sequence is -1 and the 7th term is -13. find the explicit formula for this sequence. what is a22?

Consider circle h with a 3 centimeter radius. if the length of minor arc what is the measure of zrst?

Long division setup showing an incomplete calculation. 12 is in the divisor, 6839 is in the dividend, and 5 hundreds and 6 tens is written in the quotient. 6000 is subtracted from 6839 to give 839. an unknown value represented by a box is being subtracted from 839. what number should be placed in the box to complete the division calculation?

Iknow the answer but the calculator doesn't seem to give the right one
