Answer:
28.26
Step-by-step explanation:
area of a circle is (pi)(r)^2
radius is half of the diameter
6/2=3
3 feet is the radius
a= 3.14 (3)^2
=3.14 x 9
= 28.26 feet
Hi!

Answer:
D. fourth quadrant at (4,-2)
Step-by-step explanation:
First label the quadrants, as shown in the picture below.
Right top quadrant is 1, left top quadrant is 2, left bottom quadrant is 3 and right bottom quadrant is 4.
Next, find out which quadrant the point is located in.
Forth quadrant (you can now eliminate A and B, as they indicate the 2nd quadrant.)
Now, find out what the x and y values of point are.
4 and -2
Now, since the order of points is (x,y) and the points of you can place the x and y values of the point in the corresponding place.
(x,y)-->(4,-2)
Therefore, your answer is: D. Forth quadrant at (4,-2)

Write an equation for the nth term of each geometric sequence:
1) 2,-6,18,…
2) 5,10,20,…
Answer:
see explanation
Step-by-step explanation:
The nth term of a geometric sequence is
[tex]a_{n}[/tex] = a₁ [tex]r^{n-1}[/tex]
where a₁ is the first term and r the common ratio
(1)
a₁ = 2 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{-6}{2}[/tex] = - 3 , then
[tex]a_{n}[/tex] = 2 [tex]-3)^{n-1}[/tex]

If there are 6 yellow gumballs in a machine, and that is 20% of the
total number of gumballs, how many are in the machine?
Answer:
30
Step-by-step explanation:
20x/100=6
cross multiply
600=20x
Divide both sides by the coefficient of x
600/20=x
x=30
Answer:
30
Step-by-step explanation:
20% is 1/5 of 100.
This means working backwards we can multiply 6 and 5 because 1/5's reciprocal is 5.
This gets 30 gumballs.
A particle moves along the curve y = 5x2 - 1 in such a way that the y value is decreasing at the rate of 2 units per second. At what rate is x changing when x = 1.
Given
y = 5x² - 1
differentiating both sides with respect to time t yields
dy/dt = 10x dx/dt
We're told that y decreases at a rate of 2 units/s, which means dy/dt = -2. At the moment x = 1, we have
-2 = 10•1 dx/dt ⇒ dx/dt = -2/10 = -1/5
which is to say, the x value decreases at a rate of 1/5 units/s.

Answer:
Given below.
Explanation:
Coordinates given: W( -4, -3 ) , X( 1 , -2 ), Y(2, -7 ) , Z( -3, -8)
To find the distance we will use the formula: distance=√((x2-x1)²+(y2-y1)²)
WX = √((1--4)²+(-2--3)²)
= √26
YZ = √((-3-2)²+(-8--7)²)
= √26
XY = √((2-1)²+(-7--2)²)
= √26
WZ = √(-3--4)²+(-8--3)²
= √26
WY = √(2--4)²+(-7--3)²
= 2√13
XZ = √(-3-1)²+(-8--2)²
= 2√13
Answer:
WX = √26
YZ = √26
XY = √26
WZ = √26
WY = 2√13
XZ = 2√13

Answer:
a = [tex]\frac{9}{5}[/tex] or [tex]1\frac{1}{5}[/tex]
Step-by-step explanation:
15a = 27
a = [tex]\frac{27}{15}[/tex]
a = [tex]\frac{9}{5}[/tex]
a = [tex]1\frac{1}{5}[/tex]
Answer:
a = 9/5 or a = 1 4/5
Step-by-step explanation:
15a = 27
Divide both sides of the equation by 15.
a = 27/15
Reduce the fraction by dividing the numerator and denominator by 3.
a = 9/5 = 1 4/5
Given that BD is the median of AABC and that AABC is isosceles, congruence postulate SSS can be used to prove which of the following?
i’ll give brainliest if right
Answer:
B.
Step-by-step explanation:
Because of isosceles triangle, AB = CB.
Because of the median, AD = CD.
Because of congruence of segments being reflexive, BD = BD.
By SSS, the triangles BAD and BCD are congruent.
Answer: B.
Using congruence postulate SSS we can prove that,
ΔBAD is congruent to ΔBCD.
Option B is the correct answer.
What is triangle congruency?There are ways to prove that two triangles are congruent.
- Side-Side-Side (SSS) Congruence.
The three sides of one triangle are equal to the corresponding three sides of another triangle.
- Side-Angle-Side (SAS) Congruence.
The two sides and the included angle of one triangle are equal to the corresponding two sides and included angle of another triangle.
- Angle-Side-Angle (ASA) Congruence.
The two angles and the included side of one triangle are equal to the corresponding two angles and included side of another triangle.
- Angle-Angle-Side (AAS) Congruence.
We have,
BD is the median of ΔABC.
ΔABC is isosceles.
Using congruence postulate SSS.
We have,
ΔABC is isosceles.
This means,
AB = CB
AD = DC [ BD is median ]
BD = BD [ Common sides ]
ΔBAD is congruent to ΔBCD
Thus,
ΔBAD is congruent to ΔBCD

The height of a rocket a given number of seconds after it is released is modeled by h (t) = negative 16 t squared 32 t 10. What does t represent?.
The variable t represents the number of seconds that have passed after the release of the rocket.
FunctionThe function can be defined as an expression that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
The height of a rocket a given number of seconds after it is released is modeled by,
[tex]h(t) = 6t^2 + 32t + 10[/tex]
As given in the above function, h (height) is the dependent variable which depends on the number of seconds t after the rocket is released (independent variable).
Hence we can conclude that the variable t represents the number of seconds after the rocket has been released.

Answer:
39 athletes
Step-by-step explanation:
There is a total of 45 people on the bus. This INCLUDES the athletes (A), 2 coaches and 4 managers.
Therefore, we need to sum A, 2 and 4 and equal it to 45:
2 + 4 + A = 45 so we need to used equation d.
To calculate how many athletes are on the bus, find the value of A:
2 + 4 + A = 45
Subtract 2 from both sides: 4 + A = 43
Subtract 4 from both sides: A = 39
