How many five digit numbers can be formed using digits 0-6 if repetitions are not allowed?

1 answer:

ArbitrLikvidat [17]3 years ago

4 0

6 choices for 1st digit
5 choices for 2nd digit (since we used 1 for 1st slot already)
4 for 3rd
3 for 4th
2 for 5th

so the number of numbers is 6*5*4*3*2=720 different numbers

Tell whether this function is quadratic. {(10, 50), (11, 71), (12, 94), (13, 119), (14, 146)} .

When we have consecutive values, f(10), f(11), f(12), f(13), f(14), we can make a difference table to determine the degree of f as a polynomial. A quadratic will have a constant second difference:

x 10 11 12 13 14

f(x) 50 71 94 119 146

1st diff 21 23 25 27

2nd diff 2 2 2

We got a constant second difference, so f is a polynomial of degree two.

Answer: This function is quadratic

Help !!!! Thank you!!!!

castortr0y [4]

Answer:

Option (G)

Step-by-step explanation:

Volume of the real cane = 96 in³

Volume of the model of a can = 12 in³

Volume scale factor = $\frac{\text{Volume of the model}}{\text{Volume of the real can}}$

= $\frac{12}{96}$

$=\frac{1}{8}$

Scale factor of the model = $\sqrt[3]{\text{Volume scale factor}}$

$=\sqrt[3]{\frac{1}{8}}$

$=\frac{1}{2}$

Therefore, scale factor of the model of a can = $\frac{1}{2}$ ≈ 1 : 2

Option (G) will be the correct option.

5x + 4m = 43my + 6 solve for m

pav-90 [236]

9514 1404 393

Answer:

m = (5x -6)/(43y -4)

Step-by-step explanation:

Subtract 4m+6 to separate m-terms from other terms.

5x +4m -(4m +6) = 43my +6 -(4m +6)

5x -6 = 43my -4m

5x -6 = m(43y -4) . . . . factor out m

(5x -6)/(43y -4) = m . . . . divide by the coefficient of m
