I think this is correct, Answer is <em><u>21</u></em>

Step-by-step explanation:

Step 1: Write down formula:                               a^2+b^2+c^2                  

Step 2: Plug in b and c value in formula:          a^2+20^2=29^2  

Step 3: Solve the exponents:                            a^2+400=841

Step 4: Subtract 400 from both sides:                   -400  -400

                                                                                     a^2=441

Step 5: Square root both sides:                                \sqrt{a^2}=\sqrt{441}

                                                                                     a=21

Step 6: 29+21:                    50

Step 7: 50-29:                     <u>21</u>

Given sin 0 and angle 0 is in Quadrant II, what is the exact value of cos 0 in
Anna007 [38]

sin = 3/7

1 = sin²0 + cos²0

cos²0 = 1 - 9/49

cos²0 = 40/49

cos0 = √(40) / 7

since its in Quadrant 2 the sin is positive and cos is negative

cos0 = - √(40) / 7

Suppose x represents an objects weight on Earth. Write two expressions: one that you can use to find the objects weight on Mars
tatyana61 [14]
The weight of an object is the product of its mass and the acceleration of gravity.
If g[e] is the acceleration of gravity on earth, and g[M] the same for Mars and g[m] the same for the moon,
then m[M]=m[e]g[M]/g[e] and m[m]=m[e]g[m]/g[e] where m[ ] denotes mass. Note that weight=mg (measured in newtons) while mass is in kilograms.
If g[M]=g[e]/3 and g[m]=g[e]/6 approximately. Then the weight of an object on Mars will be about a third of what it is on earth, while on the moon it would be about a sixth of what it is on earth.
