Answer:
3c2 + 4c − 15
Step-by-step explanation:
I tried my best if this is correct please sub to m YT I am a aspiring small creator
my YT is YoungGodlyFN.
Applying distributive property, the product of the given expression,
(3c-5)(c+3) is 3c² + 4c - 15.
In mathematics, the outcome of multiplying two integers is their product.
The given expression is,
(3c-5)(c+3)
Expanding this expression as,
3c(c+3) - 5(c+3)
Distribute the number inside the bracket we get,
3c² + 3x3c - 5c - 5x3
⇒ 3c² + 9c - 5c - 15
Combine like terms,
3c² + (9 - 5)c - 15
⇒ 3c² + 4c - 15
Thus,
(3c-5)(c+3) = 3c² + 4c - 15
Hence,
The product of the given expression is 3c² + 4c - 15.

A scale model of a building is 8 inches tall. The actual building is 120 feet tall. What is the scale factor of the model? (1ft. = 12 in.)
Answer:
1:180
Step-by-step explanation:
We start by multiplying the 120 feet by 12 inches to get the height of the building in inches, which is 1440.
Then, we have a ratio of 8:1440, which simplifies to 1:180 when we divide 1440 by 8.
The required scale factor of the given model is 1/180.
What is a scale image?Scale image is defined as a ratio that represents the relationship between the shape and size of a figure and the corresponding dimensions of the actual figure or object.
A building scale model is 8 inches tall. The original structure stands 120 feet tall.
Here 1 foot is equal to twelve inches which is given in the question.
As per the given situation, the required solution would be as :
Firstly we have to multiply 120 feet by 12 inches to obtain the building's height in inches, which is 1440.
The result is an 8/1440 ratio, which simplifies to 1/180 when 1440 is divided by 8.
Therefore, the required scale factor of the given model is 1/180.

Adina has a total of $1.65 in nickels and dimes. The number of dimes is 6 more than the number of nickels. How many coins are there of each type?
Choose the correct system of equations needed to solve this problem.
A
0.10d+0.05n=60.10d+0.05n=60.10d+0.05n=6
n+d=1.65n+d=1.65n+d=1.65

What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
0.5% convert to decimal
0.5/100=0.005
We need to calculate what is 0.5 percentage of 2.44.
0.005×2.44=0.0122
The cost increases after one year i.e is twelve months.
0.0122×12=0.1464
Now add 0.1464 with 0.0122
2.44+0.1464
Two point five eight six four.
=2.5864
Hence 2.5864 is the price of gas after one year.

3 of the digits 0-9 are chosen randomly by a computer what is the probability that it will choose 3 sequential digits
Answer:
The probability is 1/15
Step-by-step explanation:
Firstly, we need to get the total

The sine regression model is [tex]y =20.077 \sin(0.500x- 1.959) + 67.577[/tex], and the value of y(30) is 76.8 degrees
What is a regression model?A regression model is used to determine the association and correlation between two variables
Using a graphing calculator, the sine regression model of the dataset is:
[tex]y =20.077 \sin(0.500x- 1.959) + 67.577[/tex]
To calculate y(30), we substitute 30 for x in the equation.
So, we have:
[tex]y =20.077 \sin(0.500 * 30- 1.959) + 67.577[/tex]
Evaluate the product
[tex]y =20.077 \sin(15- 1.959) + 67.577[/tex]
Evaluate the difference
[tex]y =20.077 \sin(13.041) + 67.577[/tex]
Evaluate the sine value
[tex]y =20.077 *0.4570+ 67.577[/tex]
Evaluate the product
[tex]y =9.1752+ 67.577[/tex]
Evaluate the sum
[tex]y =76.7522[/tex]
Approximate
[tex]y \approx 76.8[/tex]
Hence, the sine regression model is [tex]y =20.077 \sin(0.500x- 1.959) + 67.577[/tex], and the value of y(30) is 76.8 degrees
