The height of a triangle is 9, the length is 5, what is the third side?

Mathematics
1 answer:
pentagon [3]3 years ago
5 0

Use the Pythagorean Theorem to solve for the third side. The third side must be the hypotenuse since the height (vertical leg) is 9, and the length (horizontal leg) is 5.

a² + b² = c², where a and b are the legs and c is the hypotenuse. Plug in 5 and 9 for a and b; solve for c.

5² + 9² = c² ⇒ 25 + 81 = c²

106 = c²

Square root both sides.

c = 10.3

Third side: 10.3

Convert r1,200 billion to million please help me out
Anika [276]
This is just converting billion to million, vice-versa.
1 million = 0.001 billion

1,200 billion = 1,200,000,000,000 
So once it is converted, the answer will be, 
1.2 x 10^15 million.

X^2+y^2=169, 3x+2y=39 please answer using substitution and each step
Oksanka [162]

Answer:

x=13,y=0

Step-by-step explanation:

We are given a system of equations

{x}^{2}  +  {y}^{2}  = 169 -  - eqn \: 1 \\ 3x + 2y = 39 -  - eqn \: 2

For equation 1,square all terms to reduce it

√x²+√y²=169

x+y=13

Make x the subject as required by the question to use substitution method

x=13-y

Plug x=13-y into eqn 2

3(13-y)+2y=39

39-3y+2y=39

39-y=39

y=39-39=0

Plug y=0 into equation 1

x+0=13

x=0

Which table represents a linear function?
bearhunter [10]

Answer:

  • Table 2

Step-by-step explanation:

<h3>Table 1</h3>
  • x- values change 1 to 4
  • y- values change inconsistently and repeat at -2

This is <u>not</u> a linear function

<h3>Table 2</h3>
  • x- values change 1 to 4
  • y- values change consistently, with common difference of -2

<u>This is a linear function</u>

<h3>Table 3</h3>
  • x- values change 1 to 4
  • y- values change inconsistently, the difference is not common

This is <u>not</u> a linear function

<h3>Table 4</h3>
  • x- values change 1 to 4
  • y- values change inconsistently, the difference is not common

This is <u>not</u> a linear function
