Answer: (C)2x + 8Y = 16

$\underline{X || 2x + 8Y = 16 || Y}$
$\underline{0\:||\:2*0 + 8Y = 16\to\:8Y = 16\to\:Y = \frac{16}{8}\:||\:Y = 2}$ (0,2)
$\underline{8\:||\:2*8 + 8Y = 16\to\:8Y = 16-16\to\:Y = \frac{0}{8}\:||\:Y = 0}$ (8,0)

H=10 cm r= 7cm calculate the volume of the cylinder

Stels [109]

Answer:

V = 1538.6 cm^3

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2h where r is the radius and h is the height

V = pi (7)^2 10

V = 3.14 (49)10

V = 1538.6 cm^3

Brittany went grocery shopping , she spent 4/7 of her money on fresh foods. she spent 2/3 of the remainder of her money on froze

pychu [463]

Answer:

$44

Step-by-step explanation:

Let the total amount of money be represented by Y

Amount spent on fresh food =

$\frac{4}{7} \times y$

Remainder =

$y - \frac{4}{7}y = \frac{3}{7} y$

Amount spent on frozen foods = two-thirds of remainder = $22

$= \frac{2}{3} \times \frac{3}{7} y = \frac{2}{7} y$

$\frac{2}{7} y = 22 \\ y = 22 \times \frac{7}{2} \\ y = 77$

The total amount for grocery shopping is $77

Therefore, Brittany spent $44 on fresh foods

$= \frac{4}{7} \times 77 \\ = 4 \times 11 \\ = 44$

By [n][n] we denote the set {1,…,n}. A function f:[m]→[n] is called monotone if f(i) \leq f(j)f(i)≤f(j)whenever i < ji

Dafna11 [192]

Answer:

There are a total of ${ 6 \choose 3} = 20$ functions.

Step-by-step explanation:

In order to define an injective monotone function from [3] to [6] we need to select 3 different values fromm {1,2,3,4,5,6} and assign the smallest one of them to 1, asign the intermediate value to 2 and the largest value to 3. That way the function is monotone and it satisfies what the problem asks.

The total way of selecting injective monotone functions is, therefore, the total amount of ways to pick 3 elements from a set of 6. That number is the combinatorial number of 6 with 3, in other words

${6 \choose 3} = \frac{6!}{3!(6-3)!} = \frac{720}{6*6} = \frac{720}{36} = 20$
