find the square simplify your answer:
(2g-9h)²
Answer:
4g² - 36gh + 81h²
Step-by-step explanation:
Apply the perfect square formula: (a - b)² = a² - 2ab + b²
(2g - 9h)² = (2g)² - 2(2g)(9h) + (9h)²
Simplify:
2g² = 4g²
-2 · 2g = -4g · 9h = -36gh
9h² = 81h²
= 4g² - 36gh + 81h²

Answer:
<B = 70°
Step-by-step explanation:
First we need to find x, lets plugin these two equations.
2x - 30 = x + 20
Then find like terms
2x = x + 50 =
x = 50
Then we plugin 50 for x
2(50) - 30 =
100 - 30 = 70
<B = 70°
Hi!
The Triangle Angle Sum Theorem states that the sum of the interior angles in all triangles will always be 180 degrees.
We can set up an equation with the given information:
40 + (2x - 30) + (x + 20) = 180
Remove parentheses:
40 + 2x - 30 + x + 20 = 180
Combine like terms:
30 + 3x = 180
Subtract 30 from both sides:
3x = 150
Divide both sides by 3:
x = 50
Now, the problem wants us to solve for angle B.
Angle B is (2x - 30) degrees. We know the value of x, so we just have to substitute:
(2x - 30)
(2(50) - 30)
100 - 30
70
Therefore, angle B is 70 degrees.

Two gears are connected by a chain. The larger gear has a linear velocity of 17π/6 inches per second. The angular velocity of the smaller gear is 34π/3 radians per minute.
What is the radius of the smaller gear?

So
[tex]\\ \rm\Rrightarrow v=r\omega[/tex]
v is linear velocityomega is angular velocity[tex]\\ \rm\Rrightarrow r=\dfrac{v}{\omega}[/tex]
[tex]\\ \rm\Rrightarrow r=\dfrac{17\pi}{6}\div\dfrac{34\pi}{3}=\dfrac{17\pi}{6}\times \dfrac{3}{34\pi}[/tex]
[tex]\\ \rm\Rrightarrow r=\dfrac{1}{4}[/tex]
[tex]\\ \rm\Rrightarrow r=0.25ft[/tex]
Convert to ft
0.25(3)=0.75ft1 min=60s
Hence
34π/3×60=34π×20=680πSo
[tex]\\ \rm\Rrightarrow r=\dfrac{17\pi}{6}\times \dfrac{1}{680\pi}[[/tex]
[tex]\\ \rm\Rrightarrow r=\dfrac{1}{40}[/tex]
[tex]\\ \rm\Rrightarrow r=0.025in[/tex]
Convert to ft
0.025(12)0.3ftNone of the above
The radius of the smaller gear is 15 feet, Option C is correct.
What is Velocity?Velocity is defined as the rate of change of distance of a body with respect to time
We can use the relationship between linear velocity and angular velocity for gears to solve this problem:
v = rω
where v is the linear velocity, r is the radius of the gear, and ω is the angular velocity.
We are given the linear velocity of the larger gear, which is 17π/6 inches per second.
v = 17π/6 inches per second
ω = (34π/3) / 60 radians per second
the radius of the smaller gear is:
r = v / ω
= (17π/6) / ((34π/3) / 60)
= 17π/6×60/(34π/3)
=17π/6×60×3/34π
= 1/6 ×60× 3/2
= 180/12
=15 feet
Hence, the radius of the smaller gear is 15 feet.

Use ≈ 3.14 and round your answer to the nearest hundredth.
To solve this problem where we need to find the radius:
⇒ find the relationship between height, volume, and radius
⇒ only equation that involves all these quantities is
⇒ Volume's equation = [tex]V = \pi r^2*h[/tex]
V: volume ⇒ 3014.4 cubic inchesr: length of radius h: length of height ⇒ 15 inches[tex]\pi[/tex] ≈ 3.14Let's set up our volume equation with known quantities
[tex]V=\pi r^2*h\\3014.4=\pi r^2*15\\3014.4 = 3.14*r^2*15\\960=15r^2\\r^2=64\\r=8[/tex]
*r cannot be negative thus r equals a positive 8
Thus the radius is 8.00 inches (rounded to the nearest hundredth)
Hope that helps!
Answer:
8.00 inches
Step-by-step explanation:
Given:
height = 15 inchesvolume = 3,014.4 cubic inchesTo find:
radiusCylinder’s Volume:
[tex]\displaystyle \large{V=\pi r^2 h}[/tex]Substitute given information in:
[tex]\displaystyle \large{3,014.4 = 3.14 \cdot r^2 \cdot 15}\\\displaystyle \large{3,014.4=47.1r^2}[/tex]
Solve for r by dividing both sides by 47.1:
[tex]\displaystyle \large{\dfrac{3,014.4}{47.1} = \dfrac{47.1r^2}{47.1}}\\\displaystyle \large{64 = r^2}\\\displaystyle \large{r = 8,-8}[/tex]
However, radius is a scalar value so it cannot be negative - the radius is 8 inches
Since you want in nearest hundredth then the radius is 8.00 inches

Given f(x) = (x + 1)(x-2)(x + 3), what are the zeros and end behavior of the function? O 1.-2. 3. continues downward to the left and upward to the night 0-1.2.-3. continues downward to the left and upward to the right O-1.2.-3. continues upward to the left and downward to the night O 1.-2.3. continues upward to the left and downward to the night
Answer:
zeros are at x = -1, x = 2 and x = -3
continues downward to the left and upward to the right
Step-by-step explanation:
Given function:
f(x) = (x + 1)(x - 2)(x + 3)
The zeros are when f(x) = 0
⇒ (x + 1)(x - 2)(x + 3) = 0
⇒ (x + 1) = 0 ⇒ x = -1
⇒ (x - 2) = 0 ⇒ x = 2
⇒ (x + 3) = 0 ⇒ x = -3
Therefore, the zeros are at x = -1, x = 2 and x = -3
If we expand the brackets of the function we get:
f(x) = (x + 1)(x - 2)(x + 3)
= (x + 1)(x² + x - 6)
= x³ + 2x² - 5x - 6
As the leading coefficient (the coefficient of x³) is positive, the end behavior of the function is:
[tex]f(x) \rightarrow + \infty, \textsf{as } x \rightarrow + \infty[/tex]
[tex]f(x) \rightarrow - \infty, \textsf{as } x \rightarrow - \infty[/tex]
So the correct option is:
"continues downward to the left and upward to the right"

A group of four numbers has an average of 14. The first three numbers are 11, 12 and 17. What's the missing number?
Answer:
16
Step-by-step explanation:
So if 4 numbers have an average of 14, that means to find the sum of all 4 numbers, you work backwards & multiply 4x14 to get 56.
Then 56-the sum of the 3 numbers you already have (11+12+17=40)
56-40=16
To double check, to find the average of 4 numbers that total 56, you divide 56 by 4 & get 14

Construct a line segment or an angle—it's your choice! Then, bisect the segment or angle you constructed.
Think about the steps you took to construct and bisect the line segment or angle.
If you chose a line segment, how are the construction steps you completed similar to the steps you would have taken to construct and bisect an angle? How are they different?
If you chose an angle, how are the construction steps you completed similar to the steps you would have taken to construct and bisect a line segment? How are they different?
There are different ways to construct an angle. The steps used in constructing a line segment are;
First, you have to put the compass at a one specific end of line segment.
Then you shift the compass slowly a little bit so it will be longer in length to half the length of line segment.
Then you have to draw arcs up and down the line.
while using the same compass width, you then draw arcs from one specific end of line.
and thereafter you put your ruler in the point where the arcs cross, and you then draw the line segment.
The differences is that to bisect an angle, one has to divide the shape or angle into two congruent parts while in construction of a line segment, there is differences in length.

The steps to construct an angle and its bisector are described above.
The angle can be defined as the one line inclined over another line.
Here,
Step 1,
Draw a random size horizontal line,
Step 2,
Take the rounder, mark the rounder 1/3 of the line drawn, put on one of the ends, and draw a horizontal semi-circle,
Step 3,
One more time, keep the rounder 1 / 3 measure of the semi-circle and cut 2 consecutive arcs, one from the initial end of the semi-circle and the other from the previous arc cut on the semi-circle.
Step - 4
Now draw a line from the center of the semi-circle through the cut arc, an angle will be formed
Step - 5,
Now cut 2 arcs from the previously cut arc intersecting each other.
Step - 6
