Answer:
28° (Answer A)
Step-by-step explanation:
Note that tan t = 8/15 = 0.533
Applying the inverse tangent function, we get
t = arctan 0.533 = 0.4900 radian
Mult. this by the radian-degree conversion factor results in: 28.072°
and when rounded off to the nearest degree, the measure of angle T is 28° (Answer A)
Answer:
Step-by-step explanation:
A = L * W
A = 22
L = 2x + 1
W = 3x + 1
now we sub
22 = (2x + 1)(3x + 1)
22 = 6x^2 + 2x + 3x + 1
22 = 6x^2 + 5x + 1
6x^2 + 5x + 1 - 22 = 0
6x^2 + 5x - 21 = 0 <======part A
(3x + 7)(2x - 3) = 0
3x + 7 = 0 2x - 3 = 0
3x = -7 2x = 3
x = -7/3 x = 3/2
I believe that x = -7/3 is an extraneous solution because when u plug it into ur length and width u get a negative number....and I dont think the sides of ur rectangle have negative values, however, it does work in ur equation and it equals 22 when multiplied...so I am not 100% sure
length = 2x + 1.......2(3/2) + 1........3 + 1 = 4
width = 3x + 1......3(3/2) + 1......9/2 + 1......9/2 + 2/2 = 11/2 (or 5.5) meters <===
Answer:
1st q answer is f(x) is one- to -one function and 2nd q answer is 2
Answer:
3/2
Step-by-step explanation:
slope=rise/run=30/20=3/2
proportional because 1*5/3*5=5/15
