Q3. A + B = 0 and AB = - 36.
What is the value of A-B?
Step-by-step explanation:
A + B = 0
A = -B
(-B)B) = -36
-B^2 = -36
B^2 = 36
B = 6, -6
So, A = -6, 6
A - B = -12
or
A - B = 12
Answer:
A - B = ± 12
Step-by-step explanation:
Given
A + B = 0 → (1)
AB = - 36 → (2)
Subtract B from both sides of (1)
A = - B ← substitute into (2)
- B(B) = - 36 ( multiply both sides by 0 1 )
B² = 36 ( take square root of both sides )
B = ± 6
Substitute into (1)
If B = 6 then A =- 6 and A-B = - 6 - 6 = - 12
If B = - 6 then A = 6 and A - B = 6 - (- 6) = 6 + 6 = 12

Step-by-step explanation:
The opening of a tunnel that travels through a mountainside can be modeled by [tex]y = - \frac {2}{15} (x - 15)(x + 15)[/tex], where x and y are measured in feet. The x-axis represents the ground.
a. Find the width of the tunnel at ground level.
b. How tall is the tunnel?
Answer:
(a) 30 feet
(b) 30 feet.
Step-by-step explanation:
Given that the opening of a tunnel that travels through a mountainside can be modeled by
[tex]y=\frac{-2}{15} (x-15)(x+15)[/tex], where x and y are measured in feet.
[tex]\Rightarrow y=\frac{-2}{15}(x^2-15^2}[/tex]
[tex]\Rightarrow y=\frac{-2}{15}{x^2-225}\cdots(i)[/tex]
(a) At the ground level, [tex]y=0[/tex]
So, the width of the tunnel at ground level is distance between the extreme point of the tunnel on the grount.
For, [tex]y=0[/tex], the extreme points of the tunnel.
[tex]0=\frac{-2}{15} (x-15)(x+15)[/tex]
[tex]\Rightarrow (x-15)(x+15) =0[/tex]
[tex]\Rightarrow x= 15, -15[/tex]
So, the extreme points of the tunnel are, [tex]x_1=15[/tex] and [tex]x_2=-15[/tex].
Hence, the width of the tunnel at the ground level
[tex]= | x_1 - x_2 |[/tex]
[tex]=|15-(-15)|[/tex]
[tex]=30[/tex] feet.
(b) The maximum height of the tunnel can be determiment by determining the maxima of the given function.
First determining the value of x for which the slope of the graph is zero.
[tex]\frac{dy}{dx}=0[/tex]
From equation (i),
-2x=0
[tex]\Rightarrow x=0[/tex]
And [tex]\frac{d^2y}{dx^2}= -2[/tex]
which is always negative, so at x=0 the value of y is maximum.
Again, put x=0 in equation (i), we have
[tex]y=\frac{-2}{15}{0^2-225}[/tex]
[tex]\Rightarrow y=30[/tex] feet.
Hence, the tunnel is 30 feet tall.
I need help with Geometry Please help me
Answer:
It would be B.
Please let me know if I'm incorrect!
What should be the first step to solve the equation?
2x + 9(x – 1) = 8(2x + 2) – 5
Combine like terms on each side of the equation.
Use the distributive property on each side of the equation.
Use the subtraction property of equality to subtract 5 from each side of the equation.
Use the addition property of equality to add 2x to each side of the equation.
Answer: B
(Use the distributive property on each side of the equation.)

Delia organised the same event last year . this year conference had a 12% increase in attendance compared to last year. 1071 people attended this year . how many attended last year?
Answer:
1071/112=1%
1%= 9.5625
100%= 9.5625*100 = 956.25
Example:
112 People attendet this year. If the increase Was also 12%, a 112 people equals 112%. So,
112/112=1
1*100= 100
However, I am suprised that 956 and 0.25 People attendet the prevoius year. Are you Sure the Numbers are correct?

Find the probability of getting a doublet in a throw of a pair of dice.
Question:
Find the probability of getting a doublet in a throw of a pair of dice.
Answer:
The probability is 1 out of 6.
Explanation:
There are a total of 6 possibilities that you get a doublet, which is {1, 1}, {2, 2}, {3, 3}, {4, 4}, {5, 5}, and {6, 6}.
The total possibilities of throwing a dice are 6 possibilities for the first dice, and 6 possibilities for the second dice. Which results in a total of 6 × 6 = 36 possibilities available.
Probability = Possibilities of getting doublet ÷ Total possibilities = 6 ÷ 36 = 1 ÷ 6.
Hopefully this answer will help you.

What is 859 divided by 3 with remainder
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
So all you have to do is use long division because a calculator won't help you with this if you are looking for a remainder so basically you just divide then you will get...
[tex]\frac{859}{3}=?\\?=286 R: 1[/tex]
So the answer is 286 and a remainder of 1.
The result of the division problem ; with the quotient and remainder respectively are 286 and 1
Numerator = 859Denominator = 3__ 286 ______quotient
______

The snooze buttonon your alarm clock activates the alarm every 5 minutes. The snooze button on your cell phone activates the alarm every 7 minutes. Both alarms activate at 7:00 A.M. You hit each snooze button as each alarm activates. At what time are both alarms activated again?
Answer: 7:35 a. M
Step-by-step explanation:
Given that:
Snooze on alarm = 5 minutes
Snooze on cellphone = 7 minutes
If both activates at 7:00 a. M
Time at which both will activate again ;
Obtain the Lowest Common Multiple of 5 and 7
_5 __|5 ___|7
_7__ |1 ___|7
