Answer:
The water droplet is in the air for two seconds.
Step-by-step explanation:
You can solve this by finding the times at which its height is zero. The lesser of the two values will be upon launch, and the greater upon landing:
y = -16x² + 32x
Let y = 0
-16x² + 32x = 0
factor -16 out:
x² - 2x = 0
complete the square:
x² - 2x + 1 = 1
and solve for x
(x - 1)² = 1
x - 1 = ±1
x = 1 ± 1
x = 0, 2
So the water is at a height of zero at zero seconds and two seconds. It's thus in the air for two seconds.

The measures of angles X and Y are the same, x degrees. The measure of angle Z is twice the measure of angle Y.
Answer:
45, 45 and 90 degrees
Step-by-step explanation:
Complete question
The measures of angles X and Y are the same, x degrees. The measure of angle Z is twice the measure of angle Y. Find the measure of each angle
Let the sum of the angles be 180 degrees
X = x
Y = x
If Z is twice the measure of angle Y, then;
Z = 2x
Taking the sum
<X + <Y + <Z = 180
x+x+2x = 180
4x = 180
x = 180/4
x = 45
since Z = 2z
Z = 2*45
Z = 90
Hence the measure of the angles X, Y and Z are 45, 45 and 90 respectively
Find the value of y when x=2; 4y=5(x-1)
Answer:
y = 1.25 and/or 1 1/4
Step-by-step explanation:
Substitute 2 for x in the equation.
4y = 5(2-1)
4y = 5(1)
4y = 5
Divide 5 by 4 to isolate the variable.
y = 1.25 and/or 1 1/4

Answer:
885.18
Step-by-step explanation:
Base = 18x18=324
triangles = 1/2(18)height
To find the height, you could divide it in half and use the 30-60-90 rule or Pythagorean theorem.
9²+b²=18²
81+b²=324
b²=324-81
b²=243
b=√243
b=15.58
So each triangle is 1/2(18)(15.58845)=140.2961.
Four of them would be 561.1845.
Now add the base.
561.1845+324=885.1844

The third side of the right triangle is 10.72 unit.
What is Pythagoras theorem?Pythagoras' Theorem states that the square of the hypotenuse side in a right-angled triangle is equal to the sum of the squares of the other two sides.
Given, the side of right triangle is;
Let H be hypotenuse = 14
And P be perpendicular = 9
Then to find third side base be B,
we use the Pythagoras theorem;
(H)² = (P)²+(B)²
Rearranging,
(B)² = (H)² - (P)²
(B)² = (14)² - (9)²
(B)² = 196 - 81
(B)² = 115
B = 10.72 unit.
Therefore, the third side is 10.72 unit.

I graphed this line below.
Start with an open dot on 7.
The reason we use an open dot is because x
does not equal 7, it is only greater than 7.
So from your open dot, draw an arrow to the right

For question 1 and 2, you should keep in mind that the sum of all angles in a triangle is 180°. 1. If the measure of one angle of a triangle is 90 degrees, you can assume that the sum of the other two triangles should be 90 degrees. Because
180 - 90 = 90
The sum of the three angles of any triangle is equal to 180 degrees.
Angle 2=127 because 180-53=127.
Angle 3=23 because 180-30-127=53
Angle 1=37 because 90-53=37
Angle 4=90
Angle 1+4=127
The measure of ∠1 is 125° .
Next x+64=110. The reason why you can do this is because ∠R is going to be an opposite interior angle. Subtract 64 from the left and right sides. x=46

Answer:
c must be less than 10 but greater than 4.
Step-by-step explanation:
In order to solve this problem, you have to apply the triangle inequality theorem. This theorem is used to determine whether or not you can form a triangle. According to the theorem, the sum of the two sides must be greater than the longest side of the triangle.
For instance, a triangle has side lengths 4, 5, and 7.
Can you form a triangle with these values?
Well, let's see
Since 4 and 5 are values less than 7, you are going to be adding those numbers. 4 plus 5 is 9. 9 is greater than 7. This means that you can form a triangle with those numbers.
For this question, you are given a triangle that has the side lengths of 3 inches, 7 inches, and c inches. The question wants the range of values. Make c the shortest side and the longest side.
Let's start with longest first.
take 3 and 7
Add them and you will get 10.
10 is greater than c. or c<10.
For the shortest side make 7 the longest
3 plus c is less than 7
subtract 3 from both sides
then you get c is less than 4. or c<4.
So you have c<4 and c>10.
combine them to make a long inequality.
4<c<10.
That is your answer.
