What does x equal to in this problem<br>​
IgorC [24]

Using the triangle, we can find the angle lengths and using those and trig ratios, find the side lengths. Lets say the top side length is "y".

Using the Law of triangles, we can find the missing angle from 180-90-70=20 deg.

Then we can use the Law of sines,

sin(70)/13=sin(20)/y

y=sin(20)*13/sin(70)

y=15.34

Finally, we use the Pythagorean Theorem, (13)^2+(15.34)^2=x^2

x = 20.1

Write an equation for the function
Mila [183]

Answer:

  m(u) = -0.25(u +2)² +1    or    -0.25u² -u

Step-by-step explanation:

The equation is fairly easily written in vertex form, as the vertex point is on a grid line intersection at (-2, 1). The parabola opens downward, so the scale factor is negative.

The vertical change from the vertex is only a fraction of a unit when u differs from the vertex by 1. It is 1 unit when u differs from the vertex by 2, so the magnitude of the vertical scale factor is 1/2² = 1/4.

Our equation will be of the form ...

  m(u) = (vertical scale factor)(u - (horizontal vertex location))² + (vertical vertex location)

For this graph, the equation is ...

  m(u) = -0.25(u +2)² +1

or, simplifying, we get ...

  m(u) = -0.25u² -u

Mark charges 100.00 for an encoding work. In addition, he charges 5.00 per page of printed output.​
o-na [289]

The total amount charged for each work can be expressed by the equation : 100 + 5x

Fixed charged per work = 100.00

Charge per page printed = 5.00

<u>Let the number pages printed be represented as x :</u>

Total amount charged for n pages can be related thus :

Fixed charge per work + (cost per page × number of pages)

100 + 5x

Therefore, the total amount charged can be expressed with the equation 100 + 5x
