Answer:

(A) -7

Step-by-step explanation:

The function is continuous if you can draw its graph without lifting your pencil. In this case, that means each of the piecewise function definitions must have the same value at x=3.

x^2 +2 = 6x +k . . . . . must be true at x=3

3^2 +2 = 6(3) +k . . . . substitute 3 for x

9 +2 -18 = k . . . . . . . . subtract 18

k = -7 . . . . . . . simplify

Answers

9514 1404 393

Answer:

C. 10 units

Step-by-step explanation:

The distance MN can be found using the distance formula.

d = √((x2 -x1)² +(y2 -y1)²)

d = √((2 -(-4))² +(3 -(-5))²) = √(6² +8²) = √100 = 10

The distance from M to N is 10 units.

The yield of strawberry plants depends on the amount of fertilizer fed to the plants. Agricultural research shows that an acre of strawberry plants will yield 770 pounds of strawberries when 70 cubic feet of fertilizer are applied. If 90 cubic of feet of fertilizer are applied, the yield will be 990 pounds of strawberries. Use linear interpolation to estimate the yield if 72 cubic feet of fertilizer are applied.

______________(and select unit of meansure)---> (cubic feet/ pounds per cubic foot/ pounds/cubic feet per pound

Answers

Answer:

[tex]792\ \text{pounds}[/tex]

Step-by-step explanation:

[tex]x_1=70[/tex] cubic feet of fertilizer is used in [tex]y_1=770[/tex] pounds of strawberries

[tex]x_2=90[/tex] cubic feet of fertilizer is used in [tex]y_2=990[/tex] pounds of strawberries

[tex]x=72[/tex] cubic feet of fertilizer is used

Linear interpolation is applied

[tex]y=y_1+\dfrac{(x-x_1)(y_2-y_1)}{x_2-x_1}\\\Rightarrow y=770+\dfrac{(72-70)(990-770)}{90-70}\\\Rightarrow y=792\ \text{pounds}[/tex]

72 cubic feet of fertilizer will yield [tex]792\ \text{pounds}[/tex] of strawberries.
