y=4 is the value y when x = - 3

It looks like y = 4.  Why is the graph black?
You just move to that x value on the x axis then go to your graph (line) and what y - value is it across from?

What is the value of x?<br><br> Please help! Thanks!
leonid [27]

Answer:

x=75

Step-by-step explanation:

We can use proportions to solve this problem.  Put the side of the small triangle over the side of the large triangle.

42           50

------ = ----------

42+63        50+x

42           50

------ = ----------

105          50+x

Using cross products

42(50+x) = 50*(105)

2100+42x = 5250

Subtract 2100 from each side

2100-2100+42x = 5250-2100

42x =3150

Divide by 42

42x/42 = 3150/42

x = 75

Use a paragraph, flow chart, or two-column proof to prove the angle congruency. Given: ∠ CXY ≅ ∠ BXY
Llana [10]

Answer:

See explanation

Step-by-step explanation:

Consider triangles CAX and BAX. In these triangles,

  • \overline{AC}\cong \overline{AB} - given
  • \angle CAX\cong \angle BAX - given
  • \overline{AX}\cong \overline{AX} - reflexive property

By SAS postulate, \triangle CAX\cong \triangle BAX

Congruent triangles have conruent corresponding parts. So,

\overline{CX}\cong \overline{BX}

Consider triangles CXY and BXY. In these triangles,

  • \overline{CX}\cong \overline{BX} - proven
  • \angle CXY\cong \angle BXY - given
  • \overline{XY}\cong \overline{XY} - reflexive property

By SAS postulate, \triangle CXY\cong \triangle BXY

Congruent triangles have conruent corresponding parts. So,

\angle XCY\cong \angle XBY

Intergal of 8sin^4(x)dx
Romashka-Z-Leto [24]
\int\limits8sin^4(x)dx =

Take the constant out \int\limits a*f(x)dx=a* \int\limitsf(x)dx

= 8 \int\limits sin^4(x)dx

\int\limits sin^4(x)dx = - \frac{cos(x)sin^3(x)}{4} = \frac{3}{4}  \int\limits sin^2(x)dx

= 8( -\frac{cos(x)sin^3(x)}{4}+ \frac{3}{4}  \int\limits sin^2(x)dx)&#10;

Use the following identify : sin^2(x) = \frac{1-cos(2x)}{2}

= 8(- \frac{cos(x)sin^3(x)}{4} + \frac{3}{4}  \frac{1}{2}(  \int\limits 1 - cos(2x)dx)

\int\limits 1dx = x

\int\limits cos(2x)dx =  \frac{1}{2} sin(2x)

Apply the sum rule :

=8(- \frac{cos(x)sin^3(x)}{4} + \frac{3}{4}  \frac{1}{2} (x- \frac{1}{2} sin(2x))

Simplify :

8( \frac{3}{8} (x- \frac{1}{2} sin(2x)) -  \frac{1}{4} sin^3(x)cos(x))

Therefore add  a constant  to the solution:

= 8 (  \frac{3}{8} (x- \frac{1}{2} sin(2x)) -  \frac{1}{4} sin^3(x)cos(x))+C

hope this helps!
