Phantasy [73]

x + y  = 24       where x and y are the 2 parts of diagonal Other diagonal wil be smaller that 24. 
x^2 + z^2 = 13^2
y^2 + z^2  = 20^2            where z  = 0.5 * length of smaller diagonal)

form last 2 equations

y^2 - x^2  = 20^2 - 13^2  =  231
 now y = 24-x so we have

(24 - x)^2    - x^2 = 231

576 - 48x = 231

48x = 345

x =  7.1875

z^2  =  13^2 - 7.1875^2 =  117.34
z =  1.83

so smaller diagonal = 21.66 cm


looks like its the third choice.

The leg of an isosceles triangle has a length 2x+4 and the base has length 3x. The
ikadub [295]

Answer:

Base = 57

Step-by-step explanation:

Given

Length = 2x + 4

Base = 3x

Perimeter = 141

Required

Determine the length of the base

The perimeter of an isosceles triangle is:

Perimeter = 2*Length + Base

141 = 2 (2x + 4) + 3x

141 = 4x + 8 + 3x

Collect Like Terms

4x + 3x = 141 - 8

7x = 133

Divide both sides by 7

x = 19

To get the base, we substitute 19 for x in Base = 3x

Base = 3 * 19

Base = 57

I need to draw an open shape made up of one or more curves
GalinKa [24]
An open shape is made up of line segments. In this type of shape there is at least one line segment that is not connected to anything at one of its endpoints, so the shape is not a closed figure. So, I am going to provide four graphs for this problem.

1. Parable

This is given by the curve:

y=x^{2}

See figure 1.

2. Cubic function.

This function is given by:

y=x^{3}

see figure 2

3. Quartic function

This curve is given by:

y=x^{4}

see figure 3

4. Cosine function

This function is given by this equation:

y=cos(x)

See figure 4.

All these curves are open shapes. So, we can find a new open shape as the sum of all these curves as follows:

y=x^{2}+x^{3}+x^{4}+cos(x)

See figure 5.

The sum of a number and two times a smaller number is 98. The bigger number is 22 less than three times the smaller number.
IgorC [24]
B>a 

<span>b=3a-22, b+2a=98, using b from the left in the right: </span>

<span>3a-22+2a=98 </span>

<span>5a-22=98 </span>

<span>5a=120 </span>

<span>a=24, and since b=3a-22, </span>

<span>b=50 </span>

<span>So the smaller number is 24 and the larger number is 50.</span>
