Answer:
choice A
Step-by-step explanation:
Sin A=12/40
sin A=.3
angle A=17.4576 degrees
Tan 17.4576=0.3145
Tan A=0.3145
Choice a, 3x(sr root of 91)/91=0.3145
Answer:
B.
linear function
linear term: -2x
constant term: –2
Step-by-step explanation:
Find the degree of the equation to determine if linear.
Linear
Find the constant of variation.
y
doesn't vary directly with
x
Hello,
Multiplying (x-1) by (4x+2) the term in x² is x*4x=4x².
If we substract 4x² the term of y in x² will be 0.
The function is not quadratic.
Since 4x*(-1)+2*x=-2x (product of terms in x) : the function is thus linear.
Constant term is -1*2=-2
f(x) = (3x+2)(-6x-3) Use the FOIL method to multiply out the factors: f(x) = -18x2 - 9x - 12x -6 Combine like terms: f(x) = -18x2 -21x - 6
The function is quadratic ax^2+bx+c. ax^2=quadratic.
bx=linear.
c=constant.
3 large beads cost 2.50 * 3 = 7.50
30-7.50 = 22.50
20-7.50 = 12.50
so they can spend between 12.50 and 22.50 on small beads
12.50 / 1.25 = 10
22.50/1.25 = 18
can buy between 10 and 18 small beads
1.25x >=12.50 and 1.25x<=22.50
Answer: 127 deg
Step-by-step explanation:
53+53 = 106
360-106=254
254/2 = 127
x = 127 deg
