The options satisfying expressions that result to zero are,
A. - 52 + 52.
E. - 83 - ( - 83).
What are additive and multiplicative inverses?A number's additive inverse is a number that is added to it until the result is zero.
A number multiplied by another such that the result is 1 is the multiplicative inverse of that number.
A number added to it's additive inverse results to zero.
From the given options the only options that satisfies the result to be zero
are,
- 52 + 52.
- 83 - (- 83).
= - 83 + 83.
As the negative signs distribute to make it a positive number.

On a rectangular hyperbola, if one point is (2, 3) and y varies inversely to x, find y when x is 6.
Answer:
y = 1
Step-by-step explanation:
y is inversely proportion to x means that ,
y ∝ 1/x or ,
[tex]y\ \alpha\ \frac{1}{x}[/tex]
When we remove the proportionality sign we get,
[tex]y=k(\frac{1}{x})\\y=\frac{k}{x} \\[/tex]
now we know the point is (2 , 3) which means it corresponds to (x , y) which furthermore means y=3 when x=2,
so we insert these values and get the value of k.
[tex]y=\frac{k}{x} \\\\3=\frac{k}{2}\\\\6=k\\[/tex]
now the equation becomes,
[tex]y=\frac{6}{x}[/tex]
now we need to find y when x is 6 so just replace x with 6
[tex]y=\frac{6}{x}\\\\y=\frac{6}{6} \\\\y=1[/tex]
so we get the value of y is 1
What is the number of possible permutations of 8 objects taken 4 at a time?
A.
24
B.
70
C.
1,680
D.
40,320
Answer:
1,680
Step-by-step explanation:
n!/(n-r)!
in this case n= 8 and r= 4
so 8!/(8-4)! = 1,680
The possible permutation of 8 objects taken at 4 a time will be 1680.
What is permutation?
The linear arrangement of the set of the orders or the linear arrangements of the numbers is called the permutation.
The number of possible permutations of 8 objects taken 4 at a time will be:-
[tex]^8C_4=\dfrac{8!}{(8-4)!}[/tex]
[tex]^8C_4=\dfrac{8!}{(4)!}[/tex]
[tex]^8C_4=\dfrac{8 \times 7\times 6\times 5\times 4\times 3\times 2}{4\times 3\times 2}=1680[/tex]
Therefore the possible permutation of 8 objects taken at 4 a time will be 1680.

Leyla will roll a number cube 1-4 and flip a coin. The coin can land on heads or tails. If Leyla rolls the number cube once and flips the coin once, which list contains only the outcomes in which the number cube land on a number greater than 3?
Answer:
[tex]Outcome = \{4H,4T\}[/tex]
Step-by-step explanation:
Given
A roll of cube numbered 1 - 4
A flip of coin
Required
Determine the possible outcomes for a number greater than 3
First, we list the sample space of the coin:
[tex]Sample\ Space = \{1,2,3,4\}[/tex]
Next, we list outcomes greater than 3
[tex]S = \{3\}[/tex]
Next, we list out the sample space (C) of a flip of coin:
[tex]C = \{H,T\}[/tex]
Where
[tex]H = Head\\T = Tail[/tex]
So, the possible outcome for a number greater than 3 is:
[tex]Outcome = \{4\} + \{H,T\}[/tex]
[tex]Outcome = \{4H,4T\}[/tex]
Whats the value of x? 3x - 5(x - 5) = -7 + 2x + 12
Answer:
x = 5
Step-by-step explanation:
Given
3x - 5(x - 5) = - 7 + 2x + 12 ← distribute and simplify left side
3x - 5x + 25 = 2x + 5
- 2x + 25 = 2x + 5 ( subtract 2x from both sides )
- 4x + 25 = 5 ( subtract 25 from both sides )
- 4x = - 20 ( divide both sides by - 4 )
x = 5

Which expression in scientific notation is equivalent to (6×10^4)(3×10^5)
A 1.8×10^10
B 1.8×10^20
C 9×10^9
D 9×10^20
Answer: A) 1.8*10^10
Step-by-step explanation:
Multiply the constants together, and multiply the multiples of 10 together.
6*3 = 18
10^4 * 10^5 = 10^9
which gives you 18 * 10^9, but that isn't in scientific notation, because 18 isn't a number between 1 and 10
so you get 18 * 10 ^9
which is equal to 1.8*10^10

A gyroscope of radius 18 centimeters rotates 35 times per minute. Find the linear velocity of a point on the edge of the gyroscope.
In one full rotation/revolution, a point on the edge travels a distance equal to the circumference of the gyroscope, or 2π (18 cm) = 36π cm. Convert the angular speed, 36π cm/rev, to linear speed:
(36π cm/rev) • (35 rev/min) = 1260π cm/min ≈ 3958 cm/min
Mose decides to launch a rocket out of the barn at Schrute farms. The equation below represents the height (in meters), of the rocket getting launched above the ground, t seconds after the rocket is launched. h(t) = -.4 (t - 2)^2 + 5 How high above the ground is the rocket before it is launched?
Height at an instance of time is given by :
h(t) = -4( t - 2 )² + 5 .....1
Differentiating above equation with respect to t .
[tex]\dfrac{dh}{dt}= -4\times ( -2 ) ( t - 2 ) \\\\\dfrac{dh}{dt}= 8(t-2)[/tex]
Now, for maximum , [tex]\dfrac{dh}{dt} = 0[/tex] .
8( t - 2 ) = 0
t = 2
Putting value of t = 2 in given equation, we get :
h( 2 ) = -4( 2 - 2 )² + 5
h( 2 ) = 5 m
Therefore, maximum height rocket can reach is 5 m.
