Answer:
$324.35
Step-by-step explanation:
249.50 x 1.30 = $324.35
Answer:
= 0
Step-by-step explanation:
-3 = x^2 + 4x + 1
0 = x^2 + 4x + 4
a = 1
b = 4
c = 4
plug the numbers into the equation to find the discriminant value...
4^2 - 4(1)(4)
16 - 16 = 0
therefore your answer is 0

Step-by-step explanation:
sin2x - sinx = 0
2sinxcosx - sinx = 0
(Double Angle Formula)
sinx(2cosx - 1) = 0
Either sinx = 0 or cosx = 1/2.
When sinx = 0,
x = 0 or x = π.
When cosx = 1/2,
x = π/3 or x = 5π/3.
Hence the solutions are
x = 0, x = π/3, x = π or x = 5π/3.
Approximately divide the region into 10 vertical strips, each with width of about 1. Next, estimate the y-coordinates of the top and bottom of each strip of this region. For example, the 1st strip stretches from approx. 2 1/4 at the bottom to approx. 2 1/4 at the top, so the total length of this strip is about 4 1/2. Since the area is (width)(height), and the width is approx. 1, the area is (4 1/2)(1) = 4 1/2.
2. Approximate the area of each of the remaining 9 strips.
3. Sum up your 10 approx. areas.
Answer:x=60
Step-by-step explanation:
110x+2400=100x+3000
-100x. -2400
10x= 600
X=60
