The quadratic equation cannonball’s path if it was launched with the same velocity, but from the ground instead would be given by:
<h3>What is the quadratic equation for the height of a projectile?</h3>
Considering the gravity, it is modeled by:
In which:
is the initial velocity.
is the initial height.
For this problem, we want:
- The same initial velocity, hence
.
- Launched from the ground, hence
.
Then, the equation is:

Answer:
Step-by-step explanation:
Let x represent the total number of red and blue beads
Angie has some red and blue beads. 40% of her beads were red. This means that the total number of red beads is
40/100 × x = 0.4x
The number of blue beads would be
x - 0.4x = 0.6x
When she lost 50 blue beads, the number of blue beads was reduced by 1/3 its original number of beads. This means that
0.6x - 50 = 0.6x - 0.6x/3
0.6x - 50 = 0.6x - 0.2x = 0.4x
0.6x - 0.4x = 50
0.2x = 50
x = 50/0.2 = 250
The number of blue beads that Angie had initially is
0.6 × 250 = 150
The number of blue beads that Angie has left is
150 - 50 = 100 beads
The number of beads that Angie has in the end is
250 - 50 = 200 beads
It's important to study and study. I recommend studying the homework or study sheet the day before the test. Most likely the teacher has added a similar problem on to the test. Add a friend to help you study.
To make it fun, buy candy and quiz yourself or friends!
If you get a problem right, them give yourself candy.
Answer:
Step-by-step explanation:
x + (x+30) + (2x) = 180
4x = 150
x = 37.5°
x+30 = 67.5°
2x = 75°
