The integers from -102 to 102 would all cancel, leaving you with
(-102) + (-101) + ... + 0 + 1 + 2 + ... + 101 + 102 + 103 + 104
= 103 + 104
= 207

Find an equation in standard form that has the following roots (-5,0) (6,0)
Answer:
x²-x-30=0
Step-by-step explanation:
so the roots are -5 and 6
we can find the exquation by knowing that
(x-root1)(x-root2)=the equation
(x+5)(x-6) distribute
x²-6x+5x-30 combine like terms
x²-x-30

A certain model of remote-control Stanley garage door opener has nine binary (off/on) switches. The homeowner can set any code sequence. (a) How many separate codes can be programmed
Answer:
[tex]Codes= 512[/tex]
Step-by-step explanation:
Given
[tex]Switches = 9[/tex]
[tex]Controls = 2[/tex] ------- on or off
Required
Determine the number of codes to be programmed
Since each switch has any of the on or off controls (i.e on or off), then:
The first switch can be coded in any of the 2 controls
The second switch can be coded in any of the 2 controls
The third switch can be coded in any of the 2 controls
Up till the ninth switch
So, we have that:
[tex]Codes= 2 * 2 *2*2*2* 2 *2*2*2[/tex]
[tex]Codes = 2^9[/tex]
[tex]Codes= 512[/tex]
Hence, there are 512 possible codes
Priya ran 1 1/2 miles today, and Tyler ran 3 3/4 miles. How many times the length of Priya’s run was Tyler’s run?
Answer:
2.5
Step-by-step explanation:
The length of Priya’s run was 2.5 times Tyler’s run.
Given
Priya ran 1 1/2 miles today, and Tyler ran 3 3/4 miles.
To determine how many times the length of Priya’s run was Tyler’s run following all the steps given below.
Let, the distance covered by Priya be x and Tyler be y.
Priya ran 1 1/2 miles today.
Then,
[tex]\rm = 1 \dfrac{1}{2}\times x\\\\= \dfrac{2\times 1+1}{2}\times x\\\\= \dfrac{2+1}{2}\times x\\\\=\dfrac{3x}{2}[/tex]
Tyler ran 3 3/4 miles.
[tex]\rm = 3 \dfrac{3}{4}\times y\\\\= \dfrac{4\times 3+3}{4} \times y\\\\= \dfrac{12+3}{4} \times y\\\\= \dfrac{15y}{4}[/tex]
On comparing both the distance
[tex]\rm \dfrac{3}{2} \times x= \dfrac{15}{4}\times y\\\\x = \dfrac{5y}{2} \\\\x = 2.5y[/tex]
Hence, the length of Priya’s run was 2.5 times Tyler’s run.

Joanne designs and sells t shirts through an online forum. she paid 80 dollars for general supplies. It costs her 2 dollars to make each t shirt. She charges 6 dollars per shirt. Determine how many t shirts Joanne needs to sell in order to break even.
Answer:
20 shirts
Step-by-step explanation:
We are told she paid 80 dollars for general supplies. It costs her 2 dollars to make each t shirt.
Total cost of production is;
80 + 2t
Where t is number of t-shirts.
We are told that She charges 6 dollars per shirt.
This means that total revenue from sales is; 6t
Now,in economics or business, break even point is the point where revenue and total cost are equal.
Thus, break even point will be at;
80 + 2t = 6t
6t - 2t = 80
4t = 80
t = 80/4
t = 20 shirts
4r + 6r - 13 = 7r + 5

Write a recursive formula and an explicit formula for the following arithmetic sequence: -1,6,13,20,27
Answer:
Recursive formula is: [tex]a_1=-1 ; \ \ a_n=a_{n-1}+7[/tex]
Explicit formula is: [tex]a_n=7n-8[/tex]
Step-by-step explanation:
We need to find recursive formula and explicit formula for arithmetic sequence -1,6,13,20,27
In the given sequence First term a₁= -1
Common difference d = 7
Finding Recursive Formula
The recursive formula is of type:[tex]a_1= First \ term[/tex] and [tex]a_n=a_{n-1}+d[/tex]
Since the First term a₁ is -1 and common difference d is 7 so, the recursive formula for given arithmetic sequence will be:
[tex]a_1=-1 ; \ \ a_n=a_{n-1}+7[/tex]
Finding Explicit Formula
The explicit formula is of type: [tex]a_n=a_1+(n-1)d[/tex]
We have
First term a₁= -1
Common difference d = 7
So, explicit formula will be:
[tex]a_n=-1+(n-1)7\\a_n=-1+7n-7\\a_n=7n-8[/tex]
So, explicit formula is: [tex]a_n=7n-8[/tex]

If 8 g of a radioactive substance are present initially and 2 yr later only 4 g remain, how much of the substance will be present after 5 yrs?
Answer:
none
Step-by-step explanation:
8-4=4
if every 2 years, 4 gallons disappear
then every 1 year, 2 gallons disappear
meaning that by 5 years there will be no substance left.

Im not explaining for each cause that would take too long, just know you plug in the y and x into the formula y1-y2/x1-x2. So for the first one, you would have -1--1 / 4--2 but when there are two subtractions signs it turns into a plus so -1+1 / 4+2
If a vector that is 1cm long represents a velocity of 10 km / h, what velocity does a vector 2 m long drawn to the same scale represent?
Answer:
V = 2000 km/h
Step-by-step explanation:
Recall that you need to follow proportionality here, and the ratio involved is: 10 km / 1 cm
then if the vector is 2 m long, then it is 200 cm long (converting it from meters to the same units as our scale which is in cm)
then we have to solve the following proportion to obtain the velocity "V":
10 km/h / 1 cm = V / 200 cm
multiply both sides by 200 to solve for V:
V = 2000 km/h
