Find the standard form of the equation of the parabola with a focus at (0, -8) and a directrix at y = 8. (5 points)

A beam has dimensions of b = 14 in., h = 30 in., d’ = 2.5 in., and d = 27.5 in. It is reinforced with 2 No. 5 bars on the compression side and 4 No. 8 bars on the tension side. The concrete strength is 2,500 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the neutral axis is c = 6.268 in., determine the strain in the compression reinforcement, ε’s.

Your next patient is a 35-year-old male.  You observe that he is struggling with a mental health issue. Which of the following would NOT increase your suspicion of a leading diagnosis of schizophrenia?

Medications to treat generalized anxiety disorder (GAD) can include a selective serotonin reuptake inhibitor (SSRI), and/or serotonin and norepinephrine reuptake inhibitor (SNRI).These medications are advantageous due to the following affects:

Most concrete design codes specify a maximum usable compressive strain at which the nominal moment strength of the section is to be calculated. For ACI 318, this maximum usable strain value is 0.003.

Eliminate the parameter. x = t – 3, y = t2 + 5 (5 points)

Two forces with magnitudes of 90 and 50 pounds act on an object at angles of 30° and 160°, respectively. Find the direction and magnitude of the resultant force. Round to two decimal places in all intermediate steps and in your final answer. (5 points)

You are considering a beam design that has dimensions of b = 16 in., h = 28 in., and d = 25.5 in. The beam is singly reinforced with all of the reinforcement in a single row. The concrete strength is 8,800 psi, and the yield strength of the reinforcement is 60,000 psi. What cross-sectional area of reinforcement is needed to achieve a strain in the reinforcement of 0.0075?

A beam has dimensions of b = 16 in., h = 28 in., and d = 25.5 in. and is reinforced with 3 No. 8 bars. The concrete strength is 6,400 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the strength Mn for this beam.

Your next patient is a 36-year-old female coming into the clinic today to see you in your primary care clinic for an exacerbation of her psoriasis. Her psoriasis was diagnosed in middle school. It seems that her lesions are getting thicker, and scalier as she gets older. She has been using different topical treatments for years and she is wondering if there is any “new treatment”.  She does not have any other health issues. She is excited about spending more time outside during the spring. She loves to run and do other outdoor activities.  Which of the following statements is true about psoriasis?
