Answer:
c
Step-by-step explanation:
a. 3in, 4in, 5 in
5^2 ? 3^2 + 4^
25 ? 9 + 16
25 = 25
Because the two sides are equal, this is a right triangle.
b. 5in, 6in, 7in
7^2 ? 5^2 + 6^2
49 ? 25 + 36
49 < 61
Because 49 < 61, this is an acute triangle.
c. 8in, 9in, 12in
12^2 ? 8^2 + 9^2
144 ? 64 + 81
144 < 145
Because 144< 145, this is an acute triangle.
Sin(180°) = 0
sec(0°)=1
4(0)+2(1)=2
A=p (1+rt)
A future value ?
p Principle 900
R interest rate 0.06
T time 9/12
A=900×(1+0.06×(9÷12))
A=940.5
Answer:
A = 100
B = 50
C = 30
Step-by-step explanation:
You can make this equation to solve:
2x+x+x-20=180
4x-20=180
+20 +20
4x=200
divide both sides by 4
200/4 = 50
x=50, B = x = 50
2x = 100 = A
x-20 = 30 = C
11x = 2y - 5
11x + 5 = 2y
2y = 11x + 5 (<u>a</u>x + b form)
y = (11x + 5)/2
y = 11x/2 + 5/2
The slope is <u>11/2</u>
