The relationship between men’s whole-number shoe sizes and foot lengths is an arithmetic sequence, where an is the foot length i
Nitella [24]

Answer:

Explicit formula for the sequence will be f(x) = 7.16 + 0.35n

Step-by-step explanation:

Step-by-step explanation:

As we know explicit formula of an arithmetic mean is given by

f(x) = a + (n-1)d

where a = first term of the sequence

n = number of term

d = common difference

Now it has been given that a men's size 9 fits a foot 10.31 inches long, means in an arithmetic sequence 9th term is 10.31. So by explicit formula

f(9) = a + (9-1)d = 10.31

⇒ a + 8d = 10.31-----(1)

Now from second statement

f(13) = a + (13-1)d = 11.71

⇒a + 12d = 11.71---------(2)

Now we subtract equation 1 from 2.

(a + 12d) - (a + 8d) = 11.71 - 10.31 = 0.40

4d = 1.40

d = 1.40/4 = 0.35

By putting the value of d in equation 1

a = 10.31 - 2.8 = 7.51

Finally we get the explicit formula of arithmetic formula as

f(x) = 7.51 + (n-1)(.35) = 7.51 + 0.35n - 0.35 = 7.16 + 0.35n

f(x) = 7.16 + 0.35n

Can anyone help me with this ​
Elden [556K]

Answer:

DE = 80.

Step-by-step explanation:

Since the 2 lines are congruent:

5x = 3x + 32

2x = 32

x = 16

So DE = 3(16) + 32

= 48 + 32

= 80.

What is the answer?
mezya [45]

Answer:

18.1 cm

Step-by-step explanation:

AD segment breakup: 11=4+7

Pythagorean Theorem:

7^2+b^2=16^2

49+b^2=256

x^2=207

b=sqrt(207)

b=3sqrt(23)

Pythagorean Theorem:

11^2+3sqrt(23)^2=c^2

121+207=c^2

328=c^2

18.11=c

So the length of AC is around 18.1 cm
