Let f be the function that determines the area of a circle (in square cm) that has a radius of r cm. That is, f ( r ) represents the area of a circle (in square cm) that has a radius of r cm.Use function notation to complete the following tasks a. Represent the area (in square cm) of a circle whose radius is 4 cm. b. Represent how much the area (in square cm) of a circle increases by when its radius increases from 10.9 to 10.91 cm. Gould Corporation uses the following activity rates from its activity-based costing to assign overhead costs to products: Activity Cost Pool Activity Rate Setting up batches $ 59.71 per batch Processing customer orders $ 73.05 per customer order Assembling products $ 4.40 per assembly hour Data concerning two products appear below: Product K91B Product F65O Number of batches 92 63 Number of customer orders 42 56 Number of assembly hours 496 903 How much overhead cost would be assigned to Product K91B using the activity-based costing system Prepare summary journal entries to record the following transactions for a company in its first month of operations. 1. Raw materials purchased on account, $86,000. 2. Direct materials used in production, $38,500. Indirect materials used in production, $23,000. 3. Paid cash for factory payroll, $50,000. Of this total, $38,000 is for direct labor and $12,000 is for indirect labor. 4. Paid cash for other actual overhead costs, $7,375. 5. Applied overhead at the rate of 125% of direct labor cost. 6. Transferred cost of jobs completed to finished goods, $62,600. 7. Sold jobs on account for $90,000 g(2). The jobs had a cost of $62,600 g(1).

B) supplementary angles. C) triangle sum. D) congruence. Which major architectural influence is illustrated by the photo above? The use of Corinthian columns and semicircular arches demonstrates the influence of classical architecture. The inclusion of glass windows points towards access to sophisticated glass manufacturing from the Arab world. The presence of geometric patterns represents a uniquely northern European addition to the structure. The use of decorative tile along the covered walkway is a common technique borrowed from Byzantine architecture. 4. The dimensions of a triangular pyramid are shown below.

A certain very nearsighted person cannot focus on anything farther than 36.0 cm from the eye. Consider the simplified model of the eye. In a simplified model of the human eye, the aqueous and vitreous humors and the lens all have a refractive index of 1.40, and all the refraction occurs at the cornea, whose vertex is 2.60 cm from the retina.Required:a. If the radius of curvature of the cornea is 0.65 cm when the eye is focusing on an object 36.0 cm from the cornea vertex and the indexes of refraction are as described before, what is the distance from the cornea vertex to the retina?b. What does this tell you about the shape of the nearsighted eye?1. This distance is greater than for the normal eye.2. This distance is shorter than for the normal eye.
