The set of ordered pairs a where
t is the time in seconds after
someone jumps out of a plane at
4000 meters to go skydiving, and d
is the displacement above the
ground
I need to find the domain and Range.
Answer: Domain is [tex][0,\infty)[/tex] and range is [0,4000].
Step-by-step explanation:
It is given that, the set of ordered pairs (t,d), where
t = the time in seconds after someone jumps out of a plane at 4000 meters to go skydiving
d = is the displacement above the ground.
It means t is independent variable and it is represented on the x-axis.
d is dependent variable and it is represented on the y-axis.
We need to find the domain and Range.
Domain is the set of input values.
Here, input is time and time can not be negative.
Domain [tex]=0\leq t=[0,\infty)[/tex]
Range is the set of output values.
Here, output is displacement above the ground which can not be negative or more than 4000 meters.
Range [tex]=0\leq d\leq 4000=[0,4000][/tex]
Therefore, domain is [tex][0,\infty)[/tex] and range is [0,4000].

7 + x - (3 + 32 = 8) = 3
Answer:X=3
Step-by-step explanation:We simplify the equation to the form, which is simple to understand
7+x-(3+32/8)=3
Simplifying:
7+x-(3+4)=3
Simplifying terms in parentheses
7+x-(+7)=3
Remove unnecessary parentheses
7+x-7=3
We move all terms containing x to the left and all other terms to the right.
+1x=+3-7+7
We simplify left and right side of the equation.
+1x=+3
We divide both sides of the equation by 1 to get x.
x=3
Which value is equivalent to 0.5?
Answer:
1. 5/10
Step-by-step explanation:
Since the options are in fractions, you have to mave 0.5 into a fraction. It is 5 tenths so 5/10 which is 1/2.
The first one is 5/10
1 x 5 = 5

There are liquids of different densities together in a container. What will happen to the liquid with the lowest density? It will move to the bottom. It will move to the top. It will bubble out as a gas. It will form a solid.
Answer:
It will move to the top.
Step-by-step explanation:
The liquid with the lowest density will move to the top. Therefore, option B is the correct answer.
Given that, there are liquids of different densities together in a container.
We need to determine what will happen to the liquid with the lowest density.
What is density?The density, of a substance, is its mass per unit volume.
The density of a liquid determines whether it will float on or sink in another liquid. A liquid will float if it is less dense than the liquid it is placed in. A liquid will sink if it is denser than the liquid it is placed in.
Now, the liquid with the lowest density will move to the top.
Therefore, option B is the correct answer.

The Division Property of Equality says that for every real nurnber a, b, and c. if a =b and c #0, then Why does the property state that c+0?
Answer:
a/c = a/c
Step-by-step explanation:
That is, if a, b, and c are real numbers such that a = b and c ≠0, then
a/c = a/c
The property state that c≠0 because division by zero does not exist.
The Division Property of Equality says that for every real number a, b, and c, if a = b and c ≠ 0, then a/c = b/c.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
When "a" and "b" are divided, the outcome of the division is the amount of "a" that each of the "b" items will receive.
Therefore, if there are 20 pens and 5 students, the amount of mangoes that each student would receive is 20 ÷ 5 or 4, or 4 pens.
When a number is divided, it can be thought of as being divided equally into a total of x parts, where x is the number of parts into which the given number is divided.
The Division Property of Equality says that for every real number a, b, and c
if a = b and c ≠ 0, then a/c = b/c.
The property state that c ≠ 0 because division by zero does not exist.

A total of $12,000 is invested in two corporate bonds that pay 7.5% and 9% simple interest. The invest wants an annual interest income of $990 from investments. What amount should be invested in the 7.5% bond?
Answer:
$13,200
Step-by-step explanation:
You need to use the simple interest formula
I = P * r * t
I = Interest accrued
P = Principal amount invested
r = Interest rate you need to divide by 100 to get it in decimal form
t = time, in years if you are given a partial year, divide the months by 12
P = $12,000
r = 7.5% = .075
t = 1
But, because we want I to equal $990 then I is
I = $990
So we ignore our P and instead solve for the P that will give us the desired result.
I = P * r * t
$990 = P * .075 * 1
$990 = P.075 Divide each side by .075
$990/.075 = P.075/.075
$990/.075 = P
$13,200 = P
So, to earn an annual interest income of $990, $13,200 will have to be invested in the 7.5% bond.
The $13,200 amount should be invested in the 7.5% bond.
It is required to what amount should be invested in the 7.5% bond.
What is simple interest ?
Simple Interest (S.I.) is the method of calculating the interest amount for a particular principal amount of money at some rate of interest.
Given that:
A total of $12,000 is invested in two corporate bonds that pay 7.5% and 9% simple interest.
We know that,
I = P * r * t
P = $12,000
r = 7.5% = .075
t = 1
I = $990
So to ignore our P and instead solve for the P that will give us the desired result.
I = P * r * t
$990 = P * .075 * 1
$990 = P.075
Divide each side by .075
$990/.075 = P.075/.075
$990/.075 = P
$13,200 = P
Therefore, $13,200 amount should be invested in the 7.5% bond.

Step-by-step explanation:
1. In the first one, we can divide both sides by -2 and then square root it, getting x^2 = -98 so x = 7i \sqrt(2).
2. We can use the quadratic formula to find out the second one.
3. We can factor 4x^2 - 21x - 18 = 0 and get (x + 6)(4x - 3).
4. In the last one, we can complete the square, getting (x + 9)^2 + 16.
What is 7x+5=5x+17
Answer:
x=6
Step-by-step explanation:
When you have 7x+5=5x+17, you try to get the variables on one side and the constants on the other. Subtract 5x from the right and from the left: 2x+5=17. Next, subtract 5 from the left and from the right: 2x=12. The last step is to get rid of the coefficient of x and to do that divide it by the coefficient(in this case divide both sides by 2). After dividing 2x and 12 by 2 you get x=6.

20x + 7 - 4x = 87
How do you do this
Answer:
x= 5
Step-by-step explanation:
20x + 7 - 4x = 87
you start by combining like terms = 20x - 4x = 16x
16x + 7 = 87
next you want to isolate the variable so you would subtract 7 from both sides .
16x + 7 = 87
-7 . -7
16x = 80
then you divide by 16 on each side
x = 5
Answer:
x=5
Step-by-step explanation:
Subtract 4x from 20x.
16x + 7 = 87
Move all terms not containing x to the right side of the equation.
Subtract
7
from both sides of the equation.
16x = 87 − 7
Subtract 7 from 87.
16x = 80
Divide each term by 16 and simplify.
