Answer:
∠ W = 51°
Step-by-step explanation:
Since WX is the diameter , then
∠ WYX = 90° ( angle in a semicircle )
The sum of the 3 angles in a triangle = 180° , then
x + x + 12 + 90 = 180
2x + 102 = 180 ( subtract 102 from both sides )
2x = 78 ( divide both sides by 2 )
x = 39
Then
∠ W = x + 12 = 39 + 12 = 51°

a toy rocket is fired into the air from the top of a barn its height H above the ground in yards after T seconds is given by the function h of T is equal to -5 t^2 + 10t + 20
1.what is the maximum height of the rocket
2. how long was the rocket in the air before hitting the ground
3.at what time(s) will the rocket be at a height of 22 yards
Answers
Answer:
45
Step-by-step explanation:
x = -30/2(-5)
x = -30/(-10)
x = 3 sec
.
Plug above into equation to find height:
h=-5t^2 + 30t
h=-5*3^2 + 30(3)
h=-5*9 + 30(3)
h=-45 + 90
h=45
Check if (1,6) is the solution to the system shown below
Answers
Answer:
no
Step-by-step explanation:
To determine if (1, 6) is a solution, substitute x = 1, y = 6 into the left side of both equations and if the value obtained equals the right side then it is a solution.
10(1) - 6 = 10 - 6 = 4 ≠ - 6
- 10(1) + 5(6) = - 10 + 30 = 20 ≠ 30
Then (1, 6 ) is not a solution to the system

Answers
Answer:
NO
Step-by-step explanation:
From the graph attached,
Equation of the line parallel to x-axis is y = 3.
Since, the line is dotted line, equation will be an inequality (having sign of < or >)
Now shaded region is below the line so equation of the inequality will be,
y < 3
Any point below the dotted line will be the solution of the given inequality.
Therefore, blue dot on the dotted line represented by y = 3 will not be the solution of the inequality.
Answer is NO.

B. 1296 m^3
Step-by-step explanation:
To find the volume of a square pyramid, multiply the base by itself twice, then divide the height by 3. After getting both answers, multiply the answers.
In this case, the base is 18.
The height is 12.
First, we must multiply the base by itself twice.
18⋅18 = 324.
Next, divide the height by 3.
12/3 = 4.
Now that we have both answers, we multiply them.
324 ⋅ 4 = 1,296.
Therefore, 1,296 cm^3 is the volume of the square pyramid.

Answer:

Step-by-step explanation:
1) we are going to do the mean :)
you add all the number together and divide by the same number
you should get 354/22 which is 16.0909....... since its round to tenth place, we place it at 16.1.
2) median, for this one, you have to lay out the numbers and see which one is in the middle, in 14,15,16,17,19, 16 is the median.
3) the number that appear the most is the mode, so right now we have
three 17s and six 16s, don't worry about the others because its not in the answer choice, so its 16.
