Answer:
It is important to use mixed numbers in real life, because it can help you find the measurements for when you are buying ingredients or baking something.
Hope this helps ;)

Answer:
sin(-pi/2) = -1
Step-by-step explanation:
sin (pi/12) cos((7pi)/12) -cos (pi/12) sin((7pi)/12) = -1
cos(-pi/2) = 0
sin(-pi/2) = -1
cos((2pi)/3) = -1/2
sin((2pi)/3) = (√3)/2
(5,465)(7,625)
slope(m) = (625 - 465) / (7 - 5) = 160/2 = 80
y = mx + b
slope(m) = 80
use either of ur points (5,465)...x = 5 and y = 465
now we sub and find b, the y int
465 = 80(5) + b
465 = 400 + b
465 - 400 = b
65 = b
equation is : y = 80x + 65...but we need it in standard form
y = 80x + 65
-80x + y = 65...multiply by -1 to make x positive
80x - y = -65 <== standard form
========================
function notation.....f(x) is the same as y
so y = 80x + 65 in function notation becomes f(x) = 80x + 65
=======================
x axis will be days rented
y axis will be total cost
to graph :
y = 80x + 65.....the slope here is 80...the y int is (0,65)
to find the x int, sub in 0 for y and solve for x
0 = 80x + 65
-80x = 65
x = - 65/80 = - 13/16....so ur x int is (-13/16,0)
and if u need to find more points on ur line....
80x - y = -65....sub in any number for x, and solve for y
Answer:
The answer is the first one ⇒ AAS
Step-by-step explanation:
∵ DB ⊥ AC
∴ m∠DBA = m∠DBC = 90° ⇒ (1)
∵ m∠A = m∠C ⇒ (2) given (from figure)
∵ DB is a common side in the two Δ ⇒ (3)
From (1) , (2) and (3)
∴ Δ ABD is congruent to Δ CBD ⇒ AAS
56,000 would be the answer. If you divide the 42,000 by 3 then add your quotient to the original number you get his salary before tax.
