What is (f⋅g)(x)? f(x)=x2−2x+3 g(x)=x3−4

Mathematics
1 answer:
Papessa [141]3 years ago
7 0

Answer:

Step-by-step explanation:

(f.g)(x) = (x² - 2x + 3) (x³ - 4)

= x²* (x³ - 4) - 2x* (x³ - 4) + 3 * (x³ - 4)

= x²*x³ - x²*4 - 2x*x³ - 2x*(-4) + 3*x³ - 3 * 4

= x⁵ - 4x²  - 2x⁴ + 8x + 3x³ - 12

= x⁵ - 2x⁴ + 3x³ - 4x² + 8x - 12

HELP ME PLEASE What is the slope of a line that passes through the points shown in this table?
tatuchka [14]

Answer:

The slope of the line is 3 ---> m = 3

Step-by-step explanation:

To find the slope of the line, you can choose any two given points from the table. Let's do (1, 3) and (2, 6)

Slope formula:  

m = (y2 - y1) / (x2 - x1)

m = (6 - 3) / (2 - 1)

m = 3 / 1

m = 3

sukhopar [10]
From a reliable source, the maximum capacity of a standard bus used as school bus is 72 students. Because the bus that Mr. Tuttle drives is already 3/4 full, only 1/4 of the capacity is unoccupied. With this, the number of the empty seats is calculated by multiplying 72 by 1/4 as shown below.
        empty seats  = (1/4)(72) = 18

Therefore, the bus could have accommodated 18 more students.
