Mathematics

Answer:

Arithmetic sequence

Step-by-step explanation:

-We notice that the difference between the number of favors already given out between any two consecutive number of party guests has an additive increment.

-This increment is called the Common Difference and has a value of 3.

-The number of tickets available is 50.

Hence, the number of tickets already given out can be calculated using the formula:

a_n=-dn+S_n\\\\n= n^{th} \ guest\\d=common \ difference\\S_n=Total \ tickets \ available\\\\\therefore a_n=-3n+50

Hence, this is an Arithmetic Sequence.

A basketball shot is taken from a horizontal distance of 5m from the hoop. The height of the ball can be modelled by the relatio
olasank [31]
This is the concept of application of quadratic expressions. Given that the height of the ball is modeled by the equation;
h=-7.3t^2+8.25t+2.1+5
The time taken for the ball to hit the ground will be given as falls;
-7.3t^2+8.25t+7.1=0
to solve for t we use the quadratic formula;
t=[-b+/-sqrt(b^2-4ac)]/(2a)
a=-7.3, b=8.25, c=2.1
t=[-8.25+/-sqrt[8.25^2+4*7.3*7.1]/(-2*7.3)
t= -0.572
or
t=1.702
since there is not negative time we take the time taken for the ball to hit the ground will be: t=1.702 sec

what is the surface area of a rectangular prism that has a height of 5cm a width of 10cm and a depth of 4cm
Kamila [148]

2(5*10)+2(10*4)+2(5*4)=

2(50)+2(40)+2(20)=100+80+40=

220 cm^2

I found the answer by finding the areas of the 3 different sides, multiplying each area by 2 since each side has another side that is equal on a rectangular prism, then adding all of them together.
