Is (x + 7) a factor of f(x) = x3 − 3x2 + 2x − 8

Mathematics
1 answer:
NNADVOKAT [17]3 years ago
8 0

Answer:

no

Step-by-step explanation:

If (x + h) is a factor of f(x) then f(- h) = 0

Thus if (x + 7) is a factor of f(x) then f(- 7) = 0

f(- 7) = (- 7)³ - 3(- 7)² + 2(- 7) - 8

        = - 343 - 147 - 14 - 8 = - 512 ≠ 0

Since f(- 7) ≠ 0 then (x + 7) is not a factor of f(x)

Aleks [24]

Complete Question

Two geometrically similar jugs have volumes of 1000 cm³and 512 cm³.They have circular bases. The diameter of the base of the larger jug is 9 cm.

Calculate the diameter of the smaller jug.

Answer:

7.2 cm

Step-by-step explanation:

To solve the above question,we have the proportion

Smaller volume/ Larger volume = (Smaller diameter/ Larger diameter)³

We are to find the smaller diameter

Hence our formula is give as

Cube root(Smaller volume/ Larger volume)= Smaller diameter/ Larger diameter

=cube root( 512/1000) = x/9

= 8/10 = x/9

Cross Multiply

10x = 8 × 9

10x = 72

x = 72/10

x = 7.2cm

Therefore, the diameter of the second jug is 7.2 cm
