Answer:
Step-by-step explanation:
A = 8 cm
B = 5 cm
C = 22 - 8 - 5 = 9 cm
Use the Pythagreom Theroem (a^2 + b^2 = c^2) if the two sides are equal to one another than it is a right triangle.
8^2 + 5^2 = 9^2
64 + 25 = 81
89 = 81
89 does not equal 81, so this is not a right triangle.
1 3/7 7 goes into 10 one time, 10-7=3
<span>These are the answers of the following items:
(1)
One weaver sells 4 blankets and 6 sweaters for $150.
4B + 6S = 150
2B + 3S = 75
The other weaver sells 8 blankets and 12 sweaters for $400.
8B + 12S = 400
2B + 3S = 100
Do the weavers charge the same amount for blankets and sweaters? NO
Write and solve a system of equations to support your answer.
</span>2B + 3S = 75
2B + 3S = 100
<span>NO SOLUTION
2.) Re-write the system to make it easier to solve, then solve to find a solution.
y = 0.005
0.006x + 0.00812y = 0.00087
y = 5
6x + 8.12y = 0.87
6x + 8.12*5 = 0.87
6x = -39.73
x = -6.62</span>
Answer:150
Step-by-step explanation:
25*1.2*5=150
The given function is
The general form of the cosine function is
a is the amplitude
2pi/b is the period
c is the phase shift
d is the vertical shift
By comparing the two functions
a = 4
b = pi
c = 0
d = 1
Then its period is
The equation of the midline is
Since the maximum is at the greatest value of cos, which is 1, then
Since the minimum is at the smallest value of cos, which is -1, then
Then substitute them in the equation of the midline
The answers are:
Period = 2
Equation of the midline is y = 1
Maximum = 5
Minimum = -3
