Answer:
9
Step-by-step explanation:
If you want the number to be divisible by three make sure the sum of all the numbers are divisible by three. Add all the numbers you have to see what they make.
3+4+2+8+4=21
So we just need to find the greatest number we can add to that to have it remain divisible by three. A number divisible by three is 30, and we can add 9 to 21 to make 30. Of course, there are other numbers we could add, but nine is the largest one-digit number that would work. Other smaller numbers include 3 and 6.
3+4+2+8+4+9=30
Now we check to see if our number is divisible by three
342984÷3 = 114328
114328 is a whole number so we know it's divisible.

What is the equation of a circle with center (-3,2) and radius 4?
(x - 3)² + (y + 2)² = 16
(x - 3)² + (y + 2)² = 2
(x - 2)² + (y - 3)² = 4
(x + 3)² + (y + 2)² = 2
(x + 3)² + (y - 2)² = 16
(x - 3)² + (y - 2)² = 4
Answer:
(x+3)² + (y-2)² = 16
Step-by-step explanation:
the equation of a circle is
(x-a)² + (y-b)² = r²
with (a,b) being the center, and r the radius.

Convert r=53sinθ−cosθ to rectangular form.
Enter your answer in slope-intercept form by filling in the boxes. Enter values so that fractions are simplified.
Answer:
[tex]y = \frac{1}{3} x + \frac{5}{3}[/tex]
Step-by-step explanation:
r = 5/(3sinθ-cosθ)
multiply both sides by (3sinθ-cosθ):
r(3sinθ-cosθ) = 5
expand:
3rsinθ-rcosθ = 5
replace rsinθ with y and rcosθ with x:
3y-x = 5
add x to both sides:
3y = x + 5
divide both sides by 3:
y = 1/3x + 5/3

Answer:
x = 18
Step-by-step explanation:
(whole secant) x (external part) = (whole secant) x (external part)
(6+x)6 = (8+10)* 8
6*(6+x) = 8(18)
Divide each side by 6
6+x = 8(18)/6
6+x = 8*3
6+x = 24
Subtract 6 from each side
6+x-6 =24-6
x = 18

Mariano is standing at the top of a hill when he kicks a soccer ball up into the air. The height of the hill is h feet, and the ball is kicked with an initial velocity of v feet per second. The height of the ball above the bottom of the hill after t seconds is given by the polynomial –16t2 + vt + h. Find the height of the ball after 2 seconds if it was kicked from the top of a 60 foot tall hill at 84 feet per second.
The height of the ball after 2 seconds is 100 feet.
What is the height function?
A height function exists as a function that quantifies the intricacy of mathematical objects. The height of an object, h(t), exists defined by the formula [tex]-16 t^{2}[/tex] + vt + h.
Given: Let, the polynomial equation be [tex]-16 t^{2}[/tex] + vt + h
h = 20 ft and v = 72 ft/s
y = [tex]-16 t^{2}[/tex] + 72t + 20
To estimate the height of the ball after 2 seconds
substitute the value of t = 2, then
y = -16 [tex]\times[/tex] 4 + 72 [tex]\times[/tex] 2 + 20
= -64 + 144 + 20
= 100 feet
The height of the ball after 2 seconds is 100 feet.

[tex]x=4; \ y=\frac{8}{\sqrt{3}}.[/tex]
Step-by-step explanation:
1) in the triangle with the angles 45; 90 and 45°: x=4√2/√2=4;
2) in the triangle with the angles 60; 90 and 30°: y=x/sin60°= 4/(√3/2)=8/√3
Answer:
x = 32 y=[tex]\frac{8}{\sqrt{3} }[/tex]
Step-by-step explanation:
solving for x
take 45 degree as reference angle
using sin rule
sin 45 = opposite / hypotenuse
[tex]\frac{1}{\sqrt{2} } = \frac{x}{4\sqrt{2} }[/tex]
do cross multiplication
[tex]4\sqrt{2} * 1 = x * \sqrt{2}[/tex]
[tex]\frac{4\sqrt{2} }{\sqrt{2} } = x[/tex]
root 2 and root 2 gets cancel.Then ,
x = 4
solving for y
take 60 degree as reference angle
using sin rule
sin 60 = opposite / hypotenuse
[tex]\frac{\sqrt{3} }{2} = \frac{x}{y}[/tex]
just now we found the value of x i.e 4 now substitute the value of x here.
[tex]\frac{\sqrt{3} }{2} = \frac{4}{y}[/tex]
do cross multiplication
[tex]2*4 = y * \sqrt{3}[/tex]
[tex]\frac{8}{\sqrt{3} } = y[/tex]

What is the slope of the graph of 3x - 7y = 10 *
3/7
O-37
O 3
O -7
Answer:
Step-by-step explanation:
Solve this for y to determine the slope. Solving for y gets our line into the slope-intercept form, y = mx + b, where the number value of m will be the slope.
-7y = -3x + 10 and
[tex]y=\frac{-3}{-7}x+\frac{10}{-7}[/tex] which simplifies down to
[tex]y=\frac{3}{7}x-\frac{10}{7}[/tex]
The value for m is 3/7 so that is the slope, the first choice given.

Answer:
9.2
Step-by-step explanation:
Using the pythagoras therorem
hyp^2 = opp^2 + adj^2
10^2 = 4^2 _+ x^2
100 = 16 + x^2
x^2 = 100 - 16

A scuba diver used the expression below to describe his position in relation to sea level.2 + (negative 20) + 8Which statement could describe the diver's movements?
Answer:
Starting on a platform 2 feet above sea level, dive down to a location that is 18 feet below sea level, and then rise 8 feet.
Step-by-step explanation:
Using the 2 + (-20) + 8 to describe movement relative to sea level ;
2 can be taken as the starting point, positive values represents elevation above sea level ;
2 can be taken as 2 feet platform above sea level ;
- 20 represents distance dived from platform, negative signifies elevation below sea level ; the distance dived relative to sea level is (-20 + platform height)
(-20 + 2) = - 18
8 feets means a final elevation of 8 above sea level (positive value).

what is x in the equation 3x+4=2x+6?
Answer:
x= 2
Step-by-step explanation:
Answer:
3x + 4 = 2x + 6
3x +4 - 2x - 6 =0
x - 2 = 0
x = 2
3(2) +4 = 2(2) + 6
6 + 4 = 4 + 6
10 = 10
3x+2=2x+6
subtracting 2 from both sides
3x+2-2=2x+6-2
3x=2x+4
subtracting 2x from both sides
3x-2x=2x-2x+4
x=4
