Solve the triangle. A = 48°, a = 32, b = 27
astraxan [27]

Answer:

C) B = 38.8°, C = 93.2°, c ≈ 43

Step-by-step explanation:

For triangle: a / sin A = b / sin B = c / sinC

32 / sin 48° = 32 / 0.743

32 / 0.743 = 27 / Sin B           sin B = 0.627

<u>B = 38.8°</u>

C = 180 - 48 - 38.8 = 93.2°     sin C = sin 93.2° = 0.998

32 / 0.743 =  c / 0.998 = 42.98     (<u>≈ 43</u>)

In the equation x^2 + mx + n = 0, m and m are integers. The only possible value for x is -3. What is the value of m?
Law Incorporation [45]

If there is only one solution, at x=-3, then the factor of (x+3) must be repeated. The equation must be equivalent to

... (x +3)² = 0

This multiplies out to give

... x² +6x +9 = 0

The value of m is 6.

_____

For finding the square of a binomial, you can either use the special form you have memorized:

... (x +a)² + x² +2ax + a²

or you can use the distributive property.

... (x +a)² = x(x +a) +a(x +a)

... = x² +ax +ax +a² = x² +2ax +a²

A wire is first bent into the shape of a square. Each side of the square is 9cm long. Then the wire is unbent and reshaped into
EastWind [94]

Answer:

5 cm

Step-by-step explanation:

the perimeter of a square with sides of 9 cm is 36 cm so the rectangle must have the same perimeter

if the length of the rectangle is 13cm, its opposite side is also 13cm

add 13 + 13 to get 26

let 'n' = width of rectangle

perimeter = 26 + n + n

36 = 26 + 2n

2n = 10

n = 5

kari74 [83]

Answer:

Senior citizen tickets = 9

Student tickets = 10

Step-by-step explanation:

We begin by converting the question into simultaneous linear equations;

Senior citizen tickets = a

Student tickets = b

4a + 6b = 96

8a + 13b = 202

to find a,

if 4a +6b = 96

a = 96/4 - 6b/4

a = 24 - 1.5b

We now substitute this into the second equation

8(24 - 1.5b) + 13b = 202

192 - 12b + 13b = 202

b = 202 - 192

b = 10

We now put the value of b in either equation

4a + 6b = 96

4a + 6(10) = 96

4a + 60 = 96

4a = 96 - 60

4a = 36

a = 9
