PLEASE HELP IM CONFUSED HOW TO FACTORISE THESE
WILL MARK BRAINLIEST
Answer:
These are all quadratics, where the x/y/a/b coefficient has been cancelled out. So it's like factorising a quadratic. What i mean by the x/y/a/b coefficient being cancelled out is for example y^2 - 1, becomes (y - 1)(y + 1). This is equal to y^2 - y + y - 1. You can see that - y + y = 0, to therefore it's not visible in the final equation, but it's there.
c) y^2 - 1 = (y - 1)(y + 1)
d) x^2 - 64 = (x - 8)(x + 8)
g) a^2 - 81 = (a - 9)(a + 9)
h) x^2 - y^2 = (x - y)(x + y)
k) 25 - x^2 = (5 - x)(5 + x)
l) 1 - b^2 = (1 - b)(1 + b)
o) x^2 - 400 = (x - 20)(x + 20)
p) 900 - y^2 = (30 - y)(30 + y)

A motor boat traveling with the current went 30mi in 3 h. Against the current, it took 5 h to travel the same distance. Find the rate of the boat in calm water and the rate of the current
Answer:
Speed of the boat is 9.4mph and the current is 15.4mph
Step-by-step explanation:
Rate= distance/ time
With current; rate= boat+ current= b+c
Against current; rate= boat - current = b- c
30=3(b+c)••••••••••••••eqn(1)
30=5(b-c)•••••••••••••••••eqn(2)
30=3b +3c••••••••••••••eqn(3)
30=5b-5c•••••••••••••••eqn(4)
Solve simultaneously
b=12mph
From eqn(3)
30=3b +3c
Divide both sides by 3, we have
10= b+c
If we make "b" the subject of the formula we have
b= (10-c)••••••••eqn(5)
Divide both side of eqn(4) by 5 we have
6=b-c••••••••eqn(7)
Substitute eqn(5) into 7
6= (10-c)-c
6= 10c-c^2
C^2-10c+6
C= 9.4 or 0.64
Substitute the highest value 9.4 into equation 7
6=b-9.4
b=6+9.4
b= 15.4
Speed of the boat is 9.4mph and the current is 15.4mph

If usual price for flight is $315.00, the airline is offering a 40% discount until the end of the month. then the cost of the flight after the discount is 126.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that an airline is trying to promote its new Boston to Atlanta flight.
the usual price for this flight is $315.00.
The discount offered by airlines is 40%.
We need to find the cost of the flight after the discount.
Convert 40% to decimal by dividing with 100.
40/100=0.4
Now multiply 0.4 with 315
0.4×315
Zero point four times of three hundred and fifteen.
126
Hence, the cost of the flight after the discount is 126.

A scientist has 50 grams of a radioactive element. The amount of radioactive element remaining after t days can be
determined using the equation

After two days the scientist receives a second shipment of 50 grams of the
same element. The equation used to represent the amount of shipment 2 remaining after t days is R8) - 50
50l
. Which
of the following is an equivalent form of the expression for the amount remaining in shipment 2?
The equivalent expression for the amount remaining is an expression that has equal value
The equivalent form of the expression for the amount remaining in shipment 2 is [tex]f(t)=50(\frac12^\frac{1}{5})^{5t- 1}[/tex]
How to determine the equivalent expressionThe initial equation of the function is:
[tex]f(t)=50(\frac12)^{\frac t{10}}[/tex]
The function after the scientist receives the second shipment after two days is:
[tex]f(t)=50(\frac12)^{t - \frac 2{10}}[/tex]
Simplify
[tex]f(t)=50(\frac12)^{t - \frac 1{5}}[/tex]
Take the LCM of the exponent
[tex]f(t)=50(\frac12)^{\frac{5t- 1}{5}}[/tex]
Express the exponent as a product expression
[tex]f(t)=50(\frac12)^{\frac{1}{5} * [5t- 1]}[/tex]
Rewrite as:
[tex]f(t)=50(\frac12^\frac{1}{5})^{5t- 1}[/tex]
Hence, the equivalent form of the expression for the amount remaining in shipment 2 is [tex]f(t)=50(\frac12^\frac{1}{5})^{5t- 1}[/tex]
