What is the area of a regular hexagon with an apothem 8.7 yards and a side 10 yards long

Answers

Hello,
Forget the apothem (it is false)

The hexagon is composed of 6 isocele triangles having like base 10 and as height=√(10²-5²)=√75=5√3
The area of one triangle is 10*5√3/2=25√3
6 triangles:150*√3=212,13203... (yd²)

The function H(t) = −16t2 + 60t + 95 shows the height H(t), in feet, of a projectile after t seconds. A second object moves in the air along a path represented by g(t) = 20 + 38.7t, where g(t) is the height, in feet, of the object from the ground at time t seconds.Part A: Create a table using integers 1 through 4 for the 2 functions. Between what 2 seconds is the solution to H(t) = g(t) located? How do you know? (6 points)

Part B: Explain what the solution from Part A means in the context of the problem. (4 points)

Answers

h(t) = -16t² + 60t + 95
g(t) = 20 + 38.7t

h(1) = -16(1²) + 60(1) + 95 = -16 + 60 + 95 = -16 + 155 = 139
h(2) = -16(2²) + 60(2) + 95 = -16(4) + 120 + 95 = -64 + 215 = 151
h(3) = -16(3²) + 60(3) + 95 = -16(9) + 180 + 95 = -144 + 275 = 131
h(4) = -16(4²) + 60(4) + 95 = -16(16) + 240 + 95 = -256 + 335 = 79

g(1) = 20 + 38.7(1) = 20 + 38.7 = 58.7
g(2) = 20 + 38.7(2) = 20 + 77.4 = 97.4
g(3) = 20 + 38.7(3) = 20 + 116.1 = 136.1
g(4) = 20 + 38.7(4) = 20 + 154.8 = 174.8

Between 2 and 3 seconds. 
The range of the 1st object is 151 to 131.
The range of the 2nd object is 97.4 to 136.1

h(t) = g(t) ⇒ 131 = 131

It means that the point where the 2 objects are equal is the point where the 1st object is falling down while the 2nd object is still going up. 

The factorization of 8x3 – 125 is (2x – 5)(jx2 + kx + 25). What are the values of j and k?

Answers

If you would like to find the values of j and k, you can do this using the following steps:

8x^3 - 125 = (2x - 5) * (jx^2 + kx + 25)
8x^3 - 125 = 2jx^3 + 2kx^2 + 50x - 5jx^2 - 5kx - 125

8x^3 = 2jx^3
4x^3 = jx^3
j = 4

2kx^2 + 50x - 5jx^2 - 5kx = 0
2kx^2 + 50x - 20x^2 - 5kx = 0
2kx^2 - 20x^2 + 50x - 5kx = 0
2kx - 20x + 50 - 5k = 0
2x(k - 10) = 5k - 50
2x(k - 10) = 5(k - 10)
k = 10

The correct result would be: j = 4 and k = 10.

j=4 k=10 on edg ;)

Jamie receive a piggy bank for her birthday every five days she earned $4.00 allowance for completing her chores at this rate how many days did it take for Jamie to save $60.00 in her piggy bank

Answers

Answer:

75 days

Step-by-step explanation:

So the total we need is $60.00, and if she Jamie gets $4 every 5 days, first I would divide 60 by 4. I get 15, so I need to do 15*5 to get 75, because the 15 stands for 15 sets of 5 days. The answer is 75. Hope this helps, and my  explanation wasn't too confusing!

Answer:

15 days

thomas and his mom take a taxi to the airport it costs a flat fee of $10 plus $4.75 a mile his mom adds a 10% tip to the total and pays the diver $58 what is the distance to the airport

Answers


This is one of those problems that you have to work backwards ...
start with the total, and work  back to the parts that make it up.

-- The total is  $58 .

-- The tip was 10% of the total fare.   
   So 
                                          1.10 (total fare)  =  58

Divide each side by 1.1 :        Total fare    = 58/1.1 =  $52.73

Out of the total fare, $10 was the flat fee before they drove
anywhere.    So the amount for mileage was  $42.73 .

Mileage was charged at the rate of  $4.75 per mile.
So the distance was
                                       42.73 / 4.75  =  9.00 miles (rounded)
                                                          
1.1(10 + 4.75x) = 58
10 + 4.75x = 580/11
4.75x = 470/11
4 3/4 x = 470/11
19/4x = 470/11
x = 470/11 * 4/19
= around 9 miles

If this helped, please consider making it the brainliest answer! :)

If it was more details, it would be easier to solve. But I can suggest a logical way. ZB + BA = ZA. If B is the midpoint it devides line on two equal lines.
