Which measurements are necessary for determining both the speed and
velocity of a moving object?
A. Distance, time, and direction
B. Direction, displacement, and distance
C. Distance, direction, and acceleration
D. Direction, time, acceleration
Answer:
b i am pretty sure
Step-by-step explanation:
Direction, displacement, and distance are the measurements are necessary for determining both the speed and velocity of a moving object
What is Speed?Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement.
The measurements which are necessary for determining both the speed and velocity of a moving object.
Speed=Distance/Time
To calculate speed we need to know the distance and time.
Velocity is the directional speed of an object in motion as an indication of its rate of change in position as observed from a particular frame of reference
Velocity=Displacement / Time
Hence Direction, displacement, and distance are the measurements are necessary for determining both the speed and velocity of a moving object

which numbers in the list are less than -0.94?
Answer:
The answer is B
The numbers -2.23 [tex]-2\frac{2}{5}[/tex], and -0.95 are numbers that are less than -0.94 option (B) is correct.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
We have a number list:
-15/16, 0.24, -2.23, 97%, [tex]-2\frac{2}{5}[/tex], -0.95
We can write these numbers such as:
-0.9375, 0.24, -2.23, 0.97, -2.4, -0.95
Now comparing the each number with -0.94
-0.9375 > -0.94
0.24 > -0.94
-2.23 < -0.94
0.97 > -0.94
[tex]-2\frac{2}{5}[/tex] or -2.4 < -0.94
-0.95 < -0.94
Thus, the numbers -2.23 [tex]-2\frac{2}{5}[/tex], and -0.95 are numbers that are less than -0.94 option (B) is correct.

1. Carly buys a pair of jeans. The store marks them down 25%. They were originally $59.80 and she has to pay a tax of 8%. What is the price of the jeans after the discount and then tax is applied?
Hey there!
The answer is $48.44
We can solve this by first finding how much the discount is.
0.25 x 59.80
14.95
The amount of the discount is 14.95, so we then take the discount off.
59.80 - 14.95
44.85
Then, we find the amount of tax.
.08 x 44.85
3.588 (round to nearest cent = 3.59)
Then, add the price of the tax onto the price of the jeans.
3.59 + 44.85
48.44

A stone is thrown straight down from a tall building. The relation h = 150 - 5t - 5t^2
approximates its path, with h in metres and t in seconds.
a) How tall is the building?
b) Factor the right side of the equation fully.
c) When does the stone hit the ground?
Answer:
a) The building is 150 m tall
b) h(t)=-5(t+6)(t-5)
c) The stone hits the ground at 5 seconds.
Step-by-step explanation:
Function Models
The path of a stone thrown down from a tall building is modeled by the function:
[tex]h(t)=150-5t-5t^2[/tex]
Where h is the height in meters and t is the time in seconds after the stone is thrown.
a) To find the height of the building, we set t=0 because it's the moment when the stone is thrown and has the same height as the building:
[tex]h(0)=150-5*0-5*0^2[/tex]
[tex]h(0)=150[/tex]
The building is 150 m tall
b) The function is
[tex]h(t)=150-5t-5t^2[/tex]
Factoring out -5:
[tex]h(t)=-5(-30+t+t^2)[/tex]
Rearranging:
[tex]h(t)=-5(t^2+t-30)[/tex]
To factor the polynomial in parentheses, we must find two numbers whose product is -30 and sum is 1. We can also use the quadratic formula to find the roots and factor later.
These numbers are 6 and -5, thus the function is:
[tex]h(t)=-5(t+6)(t-5)[/tex]
c) The stone hits the ground when h=0:
[tex]-5(t+6)(t-5)=0[/tex]
The equation has two solutions:
t = -6
t = 5
The only feasible solution is t = 5, thus the stone hits the ground at 5 seconds.
5. Solve this system of equations. 3x + 4y = 36 y = -x +8.
please help meee3333............
Answer:
x = -4 and y = 12
Step-by-step explanation:
Since you have y = -x + 8 you can substitute this into the first equation where y was so you have 3x + 4(-x + 8) = 36.
That way, there is only one variable and it is easier to solve.
3x + 4(-x + 8) = 36
3x -4x + 32 = 36
-x +32 = 36
-x = 4
x = -4
Plugging this into the equation y = -x +8,
y = -(-4) + 8
y = 4 + 8
y = 12
Footlocker has sale ln any three shirts for $55.50 meanwhile nike is having their own sale ln any five sale shirts for $79.99 which store offers the best deal what is your saving per shirt
Answer:
$55.50 for three shirts
Step-by-step explanation:
The computation is shown below:
For this question we calculate the average for both the options
For the first option, the average is
= $55.50 ÷ 3 shirts
= $18.50 per shirt
For the second option, the average is
= $79.99 ÷ 5 shirts
= $15.998 per shirt
As per the above calculation, the first option is to be best deal as the amount per shirt is high so the same is to be selected

The number of employees for a certain company has been decreasing each year by 5%. If the company currently has 900 employees and this rate continues find the number of employees in 17 years
Answer:
2062 employees
Step-by-step explanation:
Basically, you have an exponential function going on here. If you start with 900 employees and add 5 percent to the amount of employees (multiply by 1.005) seventeen times, you will get the equation [tex]E=900*1.05^{17}[/tex]. If we round down (because there can not be a fraction of an employee), there will be 2062 employees after 17 years.
