4) Engineers Rob and Kyla have designed rectangular culverts to carry water
under a new highway. They estimate that the distance under the highway is
45 m. Determine the volume of concrete they need to make the required
number of culvert pieces. Give your answer to the next highest tenth of a
cubic metre

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
