The most appropriate choice for velocity and accleration will be given by- Deacceleration of a car of 15 [tex]m/s^2[/tex] is a real world situation for which the rate of change is -15
What is velocity and acceleration?
Velocity
The distance travelled by a body per unit interval of time where the direction of the motion of a body is taken into account is known as velocity.
Velocity is a vector quantity as direction of motion of body is taken into account.
If d is the displacement of body and t is the time,
Velocity = [tex]\frac{d}{t}[/tex]
Acceleration
The rate of change of velocity of a body is called acceleration.
Acceleration is a vector quantity as direction of motion of a body is taken into account.
If [tex]\Delta[/tex]v is the change of velocity and t is the time,
Acceleration = [tex]\frac{\Delta v}{t}[/tex]
If velocity decreases then it is called Deacceleration
Here
Deacceleration of a car is 15 [tex]m/s^2[/tex]
That means rate of change of velocity of a car is -15 [tex]m/s^2[/tex]
This is a real world situation for which the rate of change is -15

Imagine that it is now 2 p.m. What time will it be when the minute hand has rotated through
1260°?
A. 5:30
B. 4:50
C. 6:00
D. 4:10
when the minute hand rotated through 1260° time will became 5:30 PM
Complete angle:-
A complete angle is a type of angle that measures 360°.A complete angle deals with one full rotation measuring 360°.
In an hour or in 60 minute, minute hand covers a 360° angle.
According to question,
initially it is 2:00PM,that is minute hand at 12 and hour hand at 2
it is given that minute hand has rotated through 1260°
1260° = 3 x 360° + 180°
which means minute hand will have three complete rotation and one half rotation.
when minute hand rotated through 360° angle then hour hand will move from 2 to 3.
And again in second rotation, when minute hand rotated through 360° angle then hour hand will move from 3 to 4.
Again in third rotation, when minute hand rotated through 360° angle then hour hand will move from 4 to 5.
As of now, minute hand have taken three complete rotation and so hour hand reached at 5
Now, when minute hand rotated through 180° (one half rotation),minute hand will reach at 6 from 12.
So, right now the position of hour hand is between 5 and 6 and the position of minute hand at 6.
hence, time will be 5:30 PM
Option A is correct

Find a point-slope form for the line with slope 1/5 and passing through the point (-4,-5).
The Point-slop form for X is X = 5Y+15, and the Point-slop form for Y is [tex]\frac{X-5}{5}[/tex], for the line with a slope 1/5 and passing through the point (-4, -5).
Finding the slop form using the formula [tex]m=\frac{Y_{1} - Y_{2} }{X_{1} -x_{2} }[/tex]
The equation for x.
Here m=1/5.
∴ [tex]\frac{1}{5}=\frac{Y-(-4)}{X-(-5)}[/tex]

Find the simple interest and the total amount after three years.Principal = 11,750 rupeesAnnual rate of interest = 7.5%Total interest = (rupees)Total amount=(rupees)
The formula for calculating simple interest is expressed as
I = PRT
where
I represents the interest
P represents the principal or initial amount invested
R represents the interest rate
T represents the time in years
From the information given,
P = 11750

What is an incenter in geometry?The incenter is the point at which all of the attitude bisectors meet in the triangle, like within the video. It is not always the middle of the triangle.
In triangle ABC, V is the incenter of the triangle.
Since, m∠SAV = 26°
And m∠SBV = 2(m ∠SAV)
= 2 × 26°
= 52°
Since Property of the incenter of a triangle;
Therefore, DG = EG = GF = 10
Since, m∠A + m∠B + m∠C = 180°
2(18)° + 34° + 2(m∠SAU) = 180°
2(m∠SAU) = 180° - 132°

Fill in the blank h(-5) • g(-2) = ________g(x) = x2. h(x) = 3x - 2
The first step to solve this question is to find the values of h(-5) and g(-2)
In order to do that, you need to use the value of x=-5 in the function h(x) and x=-2 in the function g(x).
So we have that:
[tex]\begin{gathered} g(x)=x^2 \\ g(-2)=(-2)^2=4 \\ \\ h(x)=3x-2 \\ h(-5)=3\cdot(-5)-2=-15-2=-17 \end{gathered}[/tex]Now we can calculate the product of h(-5) and g(-2):
[tex]h(-5)\cdot g(-2)=(-17)\cdot4=-68[/tex]So the value to fill the blank is -68.

{3, 6, 8} is the domain of the relation R={(3,-1)(6,4)(8,4)}
What is Function?An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.
A function has three important parts, domain, codomain and Range.
The domain of the relation R is the set of arguments i.e. first members of each ordered pair and the codomain is the set of which the values i.e. second members of all the ordered pairs.
In the Given relation
R={(3,-1)(6,4)(8,4)}
All the values in x place are domain values.
The domain equals all of the x values which are r on the left in a ordered pair
x= {3, 6, 8}

Answer:
(-3,6)----> (0,5)

Step-by-step explanation:
The translation T(3,-1) shows that we need to add three units to the x-coordinates and -1 unit to the y-coordinates, as follows in the answer above.
What is the domain of the function f(x) - 50 ? 5 + 720-2 {x: 0 < 20) {0, 1, 2, 3,.20} {a: 2 < 20} {0, 1, 2, 3,....19
The domain of a function f(x) is the set of values of the variable x for which the function is defined (has a defined finite value).
In the case of rational functions like this one, the function becomes undefined when the denominator is 0, so we can write:
[tex]\begin{gathered} 5+\sqrt[]{20-x}=0 \\ \sqrt[]{20-x}=-5\longrightarrow\text{ there is no real value for x that will satisfy this condition} \end{gathered}[/tex]As the square root will only give positive values or zero, there is no value of x that will make the square root be equal to -5. Then, this condition does not give us any discontinuity for f(x).
We have now to consider that the square root of (20-x) will not accept negative arguments in order to be in the realm of real numbers. So then, we have the condition:
[tex]\begin{gathered} 20-x\ge0 \\ 20\ge x \\ x\le20 \end{gathered}[/tex]Then, f(x) will not be defined for x that do not satisfy this condition.
We can conclude that f(x) is defined for all values of x that are equal or less than 20.
Answer: The domain is {x: x<=20}
