Find the zeros of the function. f(x) = 9×3 – 72×2 + 135x (5 points)

Honorlock is required to take quizzes in BIO 101 CRN 20220.

A rectangular beam with cross section b = 14 in., h = 22 in., and d = 19.5 in. supports a total factored uniform load of 2.20 kips/ft, including its own dead load. The beam is simply supported with a 23-ft span. It is reinforced with five No. 7 Grade 60 bars, three of which are cutoff between midspan and the support and two of which extend 10 in. past the centers of the supports. The concrete strength is 3,300 psi (normal weight). The beam has Grade 60 No. 3 stirrups satisfying ACI 318-14 Sections 9.7.6.2.2 and 9.6.3.3. The strength of the five bars is φMn = 232.3 kip-ft, and the strength of the remaining two bars is φMn = 100.3 kip-ft. Determine the distance from the support to the theoretical cutoff point (i.e. disregard ACI 318-14 Section 9.7.3.3).

Find the domain of the given function. (5 points)  f(x) =

When large amounts of steel are to be used, they can be bundled together. This decreases the required development length of each bar.

Compression-development lengths are considerably longer than tension-development lengths, because some force is transferred to the concrete by the bearing at the end of the bar.

A smooth bar embedded in concrete develops bond by _______ between the concrete and the bar and by a small amount of _______.

Determine the casting-position modification factor, ψt, for a rectangular beam with b = 16 in. and d = 24 in., three epoxy-coated No. 7 Grade 60 tension-reinforcement bars placed in the top of the beam, and No. 4 Grade 60 stirrups located every 10 in. along the span. Assume 6,000-psi lightweight concrete and a clear cover of 1.75 in.
