What is the maximum height obtained by a 12 g apple slung from a slingshot at an angle of 78° from the
horizontal with an initial velocity of 18 m/s?
Please really important anyone I have 3 min left
Answer:15.78 m
Step-by-step explanation:
Given
mass of apple m=12 g
launch angle [tex]\theta =78^{\circ}[/tex]
initial velocity [tex]u=18\ m/s[/tex]
For the projectile motion, maximum height is given by
[tex]H_{max}=\frac{u^2\sin^2 \theta}{2g}[/tex]
Putting values
[tex]H_{max}=\frac{18^2\cdot \sin^2(78^{\circ})}{2\times9.81}[/tex]
[tex]H_{max}=\frac{324\times0.956}{2\times9.81}=15.78\ m[/tex]

Step-by-step explanation:
This is an isosceles triangle. It has 2 congruent sides and congruent angles. First, It is a given that an angle measure 42. Since that is the vertex angle, it not equal to the other angles. Using the converse of base angles isosceles triangle, we now the two angles at the bottom are congruent since the lines are equal so both of the bottom angles measure (5x+14). Next, Using Triangle Interior Theorem, a triangle 3 degrees adds up to 180 degrees so we set it equal to that.
42+ 5x+14+ 5x+14=180
42+10x+28=180
10x+70=180
10x=110
x=11
You roll a fair four-sided die and a fair five-sided die together. What is the probability of rolling at least one 3. Consider the following table.
Choices:
A. 8/25
B. 4/9
C. 9/20
D. 1/2
E. 2/5
Answer:
A
Step-by-step explanation:
Bc
Probability of rolling at least one 3 is option E. 2/5.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
Given that, a fair four-sided die and a fair five-sided die are rolled together.
Probability of rolling at least one 3 means that 3 is rolled in any one of the die or both dice.
Sample space of rolling 3 are {(3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (1, 3), (2, 3), (4, 3)}
There are 8 chances of getting at least one 3 in any of the die.
Total number of outcomes = 4 × 5 = 20
Probability of getting at least one 3 = 8/20 = 2/5
Hence the required probability is 2/5.

find the value of X leave your answer in the simplest radical form :))
Answer:
A
Step-by-step explanation:
For this, you use the Pythagorean Theorem ([tex]a^2 + b^2 = c ^2[/tex])
You have the value of a (13) and the value of c (15), so you can substitute that into the formula:
[tex]13^2 + b^2 = 15^2[/tex]
[tex]169 + b^2 = 225[/tex]
subtract 169 from both sides
[tex]b^2 = 56[/tex]
[tex]b = \sqrt{56}[/tex]
Putting it into simplest radical form,

Answer :- parallelogram
Step-by-step explanation:
Answer:
Rhombus is a parallelogram which has been found to have diagonals that are NOT congruent and slopes are negative reciprocal.
★Quadrilateral is a Rhombus.★This table shows a proportional relationship between x and y.
Find the constant of proportionality (r). Using the value for r, enter an equation in the form of y = rx.
Answer:
y=2x
Step-by-step explanation:
Lets pick a proportion and plug the values in:
6=r3
Divide both sides by 3 to find r:
r=2
Replace the original equation with r:
y=2x
The equation in the form of y = rx is y = 2x.
What is a proportional relationship?A proportional relationship is a relationship between two expressions and where changes in one expression mean some constant change in another expression as well. Generally, it is represented as x/y = k, where x and y are two expressions and k is constant.
To find the constant of proportionality (r), we can use any two corresponding values of x and y and divide the y-value by the x-value. Let's use the first and second values:
r = y/x = 2/1 = 2
So the constant of proportionality is 2. To write the equation in the form of y = rx, we can substitute 2 for r:
y = 2x
Therefore, the equation in the form of y = rx is y = 2x.

x = 72°

Step-by-step explanation:
Properties of a kite,
1). At least on pair of opposite angles of a kite are equal.
2). Diagonal of a kite intersect each other at 90°.
3). Diagonals are the angle bisectors of opposite angles.
By these properties,
m∠AED = 90°
In ΔAED,
m∠AED + m∠EDA + m∠DAE = 180° [Triangle sum theorem]
90° + 18° + m∠DAE = 180°
m∠DAE = 180° - 108°
= 72°
Since, diagonal AC is an angle bisector of angle DAB,
x = 72°
In ΔABC,
m∠ABC + m∠BCA + m∠CAB = 180°
m∠ABC + 29° + x° = 180°
m∠ABC + 29° + 72° = 180°
m∠ABC = 180° - 101°
m∠ABC = 79°
Since, opposite angles ∠ADC and ∠ABD are equal in measure,
m∠ABC = m∠ADC = 79°
79° = (18 + y)°
y = 79 - 18
y = 61°
Triangle ABC has a perimiter of 22cm AB=8cm BC=5cm by calculation deduce whether triangle ABC is a right-angled triangle
Answer:
ABC is not a right triangle
Step-by-step explanation:
The computation is shown below:
AC is
= Perimeter - (AB + BC)
= 22 - (8+5)
= 22 - 13
= 9
Now
= 9^2 + 13^2
= 81 +169
= 250
And, the perimeter is
= 22^2
= 484
Since the amount are not equivalent therefore ABC is not a right triangle
