Answer:
See below.
Step-by-step explanation:
We need to prove that tanx + secx = secx(1 + tanx / secx) (because their quotient = 1).
Taking the right side of the identity:
secx(1 + tanx / secx) Distributing the sec x we get:
secx + tanx = the left side.
Answer: 8 friends
Step-by-step explanation:
35(at first)-3(left)=32
32(given away) divided by 4(to each friend)= 8 friends
Answer:
Answer is 5
Step-by-step explanation:
Okay hun so let me tell u what's up here
They give us this equation and ask for the 'roots'
(x+5)^3(x-9)(x+1)
Now lemme tell you the roots of this one
-5, 9, -1
you get this from making each of them 0
The answer to this would be "3" because there are 3 roots, buT wait theRe'S mOre
(x+5) goes 3 times
So thy must recount it
-5, -5, -5, 9, -1 <-- These are the roots
that's 5 roots in total
....also I did this on edgen, got it right with 5
Answer:
perimeter = 44.05 yd
area = 164.25 yd^2
Step-by-step explanation:
The figure is shaped like a trapezoid with a semicircle.
Perimeter:
We add the lengths of the three sides of the trapezoid and the circumference of the semicircle.
perimeter = 15 + 11.2 + 10 + 0.5 * 3.14 * 5
perimeter = 44.05 yd
Area:
We find the area of the trapezoid and add to it the area of the half circle.
area = 0.5(10)(10 + 15) + 0.5(3.14)(5^2)
area = 164.25 yd^2
