Stells [14]

Answer:

Distance traveled by the snowball  = 45feet

Step-by-step explanation:

The distance traveled by the snowball = distance of hypothenus for both Right angle triangle

1st pythagoras =

X² = 20² + 15²

X = (20² + 15²)¹/² = 25 feet

2nd pythagoras =

X² = 16² + 12²

X = (16² + 12²)¹/² = 20 feet

Distance traveled by the snowball = 20 + 25 = 45feet

What is the general form of the equation for the given circle centered at O(0, 0)?
Vesna [10]

 

hello :<span>
<span>an equation of the circle Center at the O(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : a =0 and b = 0 (Center at the origin)
r = AO
r² = (AO)²
r² = (4-0)² +(5-0)² = 16+25=41
an equation of the circle that satisfies the stated conditions.
Center at the origin, passing through B(4, 5) is :  x² +y² = 41</span></span>

x² +y² - 41=0

Consider the expression below. Assume the variable m represents an integer. 6m(3m + 21) Enter an expression in the box that uses
Monica [59]

Answer:

(a)\ 6m(3m + 21) = 9(2m^2 + 14m)

(b) Yes, it is divisible by 9

Step-by-step explanation:

Given

6m(3m + 21)

Solving (a): Complete the blanks

6m(3m + 21) = 9 [\ ]

Expand the bracket

6m(3[m + 7]) = 9 [\ ]

6m*3(m + 7) = 9 [\ ]

Express 6m as 2m * 3

2m*3*3(m + 7) = 9 [\ ]

2m*9(m + 7) = 9 [\ ]

Rewrite as:

9 * 2m(m + 7) = 9 [\ ]

Multiply the bracket by 2m

9 * (2m^2 + 14m) = 9 [\ ]

Divide both sides by 9

2m^2 + 14m = [\ ]

<em>Hence, the bracket will be filled with: </em>2m^2 + 14m<em></em>

<em>So:</em>

6m(3m + 21) = 9(2m^2 + 14m)

Solving (b): Is 6m(3m + 21) divisible by 9?

In (a), we have:

6m(3m + 21) = 9(2m^2 + 14m)

The leading factor "9" implies that the expression is divisible by 9
