Find the exact value of x .

Mathematics
1 answer:
Kruka [31]4 years ago
5 0

Answer:

<h2>x = 6.72</h2>

Step-by-step explanation:

       From the diagram, \Delta XZY is right angled.

Also XZ=24,YZ=7,XY=25,WZ=x

      Area of a triangle = \frac{1}{2}\times Base\times Height

For \Delta XZY, consider calculating area in two ways taking XZ as the base and XY as the base. Both areas must be same because they are areas of same triangle.

\frac{1}{2}\times XZ\times YZ=\frac{1}{2}\times XY\times WZ\\24\times 7=25\times x\\x=6.72

∴ x=6.72\text{ }units

Does the graph represent a function?
Harrizon [31]

Answer:

The graph does represent a function because it passes the vertical line test!

Step-by-step explanation:

A vertical line test means if you put a vertical line over any area on the graph it shouldn't hit the line more than once :)

If f(x) = -x2 + 4x - 9 and g(x) = x - 8, find g(f(-1))
Paha777 [63]

Answer:

-22

Step-by-step explanation:

f(x) = -x2 + 4x - 9

g(x) = x - 8,

g(f(-1))

First find f(-1)

f(-1) = - (-1)^2 + 4(-1) - 9 = -1 -4-9 = -14

The find g(-14)

g(-14) = -14-8 = -22

Use synthetic division to evaluate (3x2 − 6x + 3) ÷ (x − 1). 3x − 9 3x2 − 3x 3x − 3 3x2 − 6
Viefleur [7K]

Answer:

\frac{\left(3x^2-6x+3\right)}{\left(x-1\right)3x-93x^2-3x^3x-33x^2-6}: -\frac{\left(x-1\right)^2}{x^4+41x^2+x+2}
\frac{3x^2-6x+3}{\left(x-1\right)\cdot \:3x-126x^2-3x^3x-6}
\frac{3\left(x-1\right)^2}{\left(x-1\right)\cdot \:3x-126x^2-3x^3x-6}
\frac{3\left(x-1\right)^2}{-3\left(x^4+41x^2+x+2\right)}
\frac{\left(x-1\right)^2}{-\left(x^4+41x^2+x+2\right)}
-\frac{\left(x-1\right)^2}{x^4+41x^2+x+2}
