Answer:
78 inches
Step-by-step explanation:
perimeter of a kite formula: 2(a+b)
a= 18 inches
b= 21 inches
2(18+21)
2(39)
78 inches
3/8 + 1/16= 7/16
so it's c. 7/16
Answer:1385.44mm sq
Step-by-step explanation: surface area of a circle = pi x radius squared
3.142 x 21 squared
Answer:
y =
x + 6 or y =
x - 0.375
Step-by-step explanation:
For 2 lines to be perpendicular, their slopes must be <u>negative reciprocals</u>. In order to find the perpendicular of y - 4x - 6 = 0:
SLOPE INTERCEPT FORM: y = 4x + 6
SLOPE OF LINE A: m=4
SLOPE OF LINE B (the one you are looking for): m=
Since I don't know if you meant that they intercept on the x or y axis I will do both.
<u>y-axis</u>
y-6=
(x-0)
y =
x+6
<u>x-axis</u>
y-0=
(x-1.5)
y=
x-0.375
