A rectangle has a perimeter of 64 inches. The length is 6 more than the width.

BigorU [14]

Let width be x so
Length is equal to x+6
Perimeter= 2(l+b)
So perimeter=2(x+x+6)
P=2(2x+6)
4x+12=64 (given)
Send 12 to the other side then,
4x=64-12=52
X=52/4=13

Find the second, fourth, and eleventh terms of the

tekilochka [14]

Answer:

The second term is -6 , the fourth term is 0 , the eleventh term is 21

Step-by-step explanation:

* Lets revise the explicit formula

- An explicit formula will create a sequence using n, the number

position of each term.

- If you can find an explicit formula for a sequence, you will be able

to quickly and easily find any term in the sequence by replacing

n with the number of the term you want

- It defines the sequence as a formula in terms of n.

* Now lets solve the problem

- The formula of the sequence is A(n) = -9 + (n - 1)(3)

- A(n) is any term in the sequence

- n is the position of the number

- To find the second term put n = 2

∵ n = 2

∴ A(2) = -9 + (2 - 1)(3) = -9 + (1)(3) = -9 + 3 = -6

* The second term is -6

- To find the fourth term put n = 4

∵ n = 4

∴ A(4) = -9 + (4 - 1)(3) = -9 + (3)(3) = -9 + 9 = 0

* The fourth term is 0

- To find the eleventh term put n = 11

∵ n = 11

∴ A(11) = -9 + (11 - 1)(3) = -9 + (10)(3) = -9 + 30 = 21

* The eleventh term is 21

What are my zeros (x^2 - 8x + 1)?

Pavel [41]

Answer:

x= 7.87298334621 x=.12701665379

Step-by-step explanation:

This is in standard form so we have to factor this into

x^2-8x + 16 + 1 = 16

(x-4)^2 = 15

(x-4) = $\sqrt{15\\}$

x-4= ± 3.87298334621

x-4 = 3.87298334621 x-4= -3.87298334621

x= 7.87298334621 x=.12701665379

Bean seeds from supplier A have 85% germination rate and those from supplier B have 75% germination rate. A seed-packing company

VikaD [51]

Answer:

0.79 = 79% probability that a seed selected at random from the mixed will germinate.

Step-by-step explanation:

Probability of a seed germinating:

85% of 40%(from company A)

75% of 60%(from company B)

Then

$P = 0.85*0.4 + 0.75*0.6 = 0.79$

0.79 = 79% probability that a seed selected at random from the mixed will germinate.
