A cricket ball is hit from a point A with velocity of (pi + qj)ms-1 at an angle theta above the
horizontal, i and j are the unit vectors horizontally and vertically upwards respectively. The point
A is 0.8 m vertically above the point 0, which is on horizontal ground.
The ball takes 4 seconds to travel from A to B, where B is on the ground and OB = 64 m, as
shown in the diagram. By modelling the motion of the ball as that of a particle moving freely under gravity,
a) find the value of p and the value of q
b) find the initial speed of the ball
c) find the exact value of tan theta
d )find the length of time for which the cricket ball is at least 5 m above the ground.
e )State an additional physical factor which may be taken into account in a refinement of the above model to make it more realistic.

Answers
Answer: -25
Step-by-step explanation:
Since you're adding two negatives, you will be able to add them just like if you were adding positive answers. So... 10+15=25 and all you got to do is to pop the negative in front of it.
So the final answer is -25.

Answer: 105
Step-by-step explanation: Skate World offers birthday parties for a fee of $180 plus $2 per person. If you can spend no more than $210 on
your party, what is the maximum number of people who (can) attend?
The keyword "can" is telling us to basically tell us to find how much people (can) attend. Not how much will attend.

A homeowner wishes to put a fence around a space in her yard to create a dog pen. The space that she wants to fence in is shown below where each unit on the
graph represents one foot,

How many feet of fencing will the homeowner need to build the dog pen?
38 + 4V2
54
52
38 + 1072
Answers
Answer: the answer is C 52
Step-by-step explanation:
The length of the fencing needed is given by the lengths of the lines
that goes around the space she wants to fence shown in the graph.
Correct response:
The amount of fencing the homeowner needs is; 38 + 10·√2Methods used to find the length of fencing neededThe coordinates of the vertices of the fenced area are presented as
follows;
A(-7, 7), B(4, 7), C(6, -7), and D(-7, -7)
Therefore, by finding the distance between the given points, we have;
Length of AB = 4 - (-7) = 11
Length of AD = 7 - (-7) = 14
Length of CD = 6 - (-7) = 13
Length of BC = √((6 - 4)² + (-7 - 7)²) = [tex]\sqrt{200}[/tex] = 10·√2
Length of fencing needed, L = AB + AD + CD + BC
Which gives;
L = 11 + 14 + 13 + 10·√2 = 38 + 10·√2
The length of fencing needed, L = 38 + 10·√2Learn more about the distance between points given the coordinates here:

What degree measure is equivalent to 5π?
900°
450°
36°
90°
Answers
Answer:
900
Step-by-step explanation:
The equivalent degree measure of 5π ard is 900°.
What are the measure of reference angles according to quadrats?We have I, II, III, IV quadrants.
In quadrant I the referece angle Ф is Ф.
In quadrant II the referece angle Ф is (π - Ф).
In quadrant III the referece angle Ф is (π + Ф).
In quadrant IV the referece angle Ф is (2π - Ф).
We know π is equal to 180°.
The conversion of radian to degrees is we multiply the radian value by 180°/π.
Given, The radian measure is 5π.
Therefore, the equivalent degree measure is,
= (5π)×(180/π).
= (5×180)°.
= 900°.

Answer:
(a+2) (a-18)
Step-by-step explanation:
Factoring a2-16a-36
The first term is, a2 its coefficient is 1 .
The middle term is, -16a its coefficient is -16 .
The last term, "the constant", is -36
Step-1 : Multiply the coefficient of the first term by the constant 1 • -36 = -36
Step-2 : Find two factors of -36 whose sum equals the coefficient of the middle term, which is -16 .
-36 + 1 = -35
-18 + 2 = -16 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -18 and 2
a2 - 18a + 2a - 36
Step-4 : Add up the first 2 terms, pulling out like factors :
a • (a-18)
Add up the last 2 terms, pulling out common factors :
2 • (a-18)
Step-5 : Add up the four terms of step 4 :
(a+2) • (a-18)
Which is the desired factorization

Step-by-step explanation: add 8 to both sides .( 8+10 < b - 8+8) now you get 18 < b .But variable must go first so you put b and then flip the inequality sign to > and put 18.So now you have b >18 as your inequality.
