in right triangles ABC, angle A and B are complementary angles. the value of cos a is 5/13 is the value of sin B
blagie [28]
We know that
<span>In a right triangle
if A and B are complementary angles
cos A=sin B
therefore
if cos A=5/13
then sin B=5/13

the answer is
sin B=5/13</span>

Let $x$ be the positive number such that $2x^2 = 4x + 9.$
loris [4]

Solve for x. I'll do it by completing the square:

2x² = 4x + 9

2x² - 4x = 9

x² - 2x = 9/2

x² - 2x + 1 = 11/2

(x - 1)² = 11/2

x - 1 = ± √(11/2)

x = 1 ± √(11/2)

x = 1 ± √22/2

x = (2 ± √22)/2

Take the solution with the positive square root. Then it follows that a = c = 2 and b = 22. So a + b + c = 26.

The number of pumps in use at both a six-pump station and a four-pump station will be determined. Give the possible values for e
notsponge [240]

Answer:

a. T = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

b. X = { -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6}

c. U = {0, 1, 2, 3, 4, 5, 6}

d. Z = {0, 1, 2}

Step-by-step explanation:

n1 = 6 pumps

n2 = 4 pumps

a. The total number of pumps in use:

The number of pumps in use can range from 0 (no pumps used in both stations) to 10 (all pumps used in both stations), assuming all integers in between. Thus, the set T is:

T = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

b. The difference between the numbers in use at stations 1 and 2 can range from -4 (no pumps in station 1 and all pumps in station 2 being used) to 6 (all pumps in station 1 and no pumps in station 2 being used), assuming all integers in between. Thus, the set X is:

X = { -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6}

c. The maximum number of pumps in use at either station is given by the possible numbers of pumps at use in station 1 (From 0 to 6). The set U is:

U = {0, 1, 2, 3, 4, 5, 6}

d. The number of stations having exactly two pumps in use can be neither, one or both. The set Z is:

Z = {0, 1, 2}
