Subtract 11a2+42a-6 from 14a2-24a+7
The values of subtraction of 11a²+42a-6 from 14a²-24a+7 is
3a² - 66a + 1.
What is Expression?
Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows: Expression: (Math Operator, Number/Variable, Math Operator)
We have to Subtract 11a²+42a-6 from 14a²-24a+7.
So, the subtraction is as follows
= 14a²-24a+7 - ( 11a²+42a-6)
= 14a²-24a+7 - 11a² - 42a + 6
= 14a²- 11a² -24a - 42a + 7- 6
= 3a² - 66a + 1

For the following geometric sequence, find the recursive formula.
{-80, 20, -5, ...}
Answer:
[tex]x_{n+1}=-\frac{x_{n}}{4}[/tex]
Step-by-step explanation:
We can get geometric sequence dividing each term by -4
So we will have:
[tex]x_{n+1}=\frac{x_{n}}{-4}=-\frac{x_{n}}{4}[/tex]
We can prove it putting the first value in this recursive equation:
x₁=-80
n = 1
[tex]x_{2}=-\frac{x_{1}}{4}=-\frac{-80}{4}=20[/tex]
If x₂ = 20, the next value will be:

In a programming team of 20 persons, 1/4 are women and 3/4 are men. to obtain a team with 40% women, how many women should be hired?
To obtain a team with 40% women in a programming team of 20 people, we need to find out how many women should be hired. Currently, there are 5 women in the team (1/4 of 20). By setting up an equation and solving for x, we find that 5 women should be hired.
Explanation:To obtain a team with 40% women in a programming team of 20 people, we need to find out how many women should be hired. We know that currently 1/4 of the team are women, which means there are 5 women in the team (20 * 1/4 = 5). To find out how many women should be hired, we subtract the number of women in the team from the target number of women in the team:
Number of women to be hired = Target number of women - Current number of women
Number of women to be hired = 0.4 * (20 + x) - 5
Where x is the number of women to be hired. Now we can solve for x:
0.4 * (20 + x) - 5 = x
Distribute and simplify:
8 + 0.4x - 5 = x
Combine like terms:
0.4x - x = 5 - 8
0.6x = 3
Divide both sides by 0.6:
x = 3 / 0.6
x = 5
So, 5 women should be hired to obtain a team with 40% women.

Assume that y varies inversely with x. If y=12 when x=5, find y when x=3
When y varies inversely with x, they follow the rule y = k/x. If y=12 when x=5, the constant 'k' is found to be 60. Using this constant, when x=3, y is found to be 20.
Explanation:In mathematics, when we say that y varies inversely with x, it means that as x increases, y decreases proportionally, and vice-versa. Y and x follow the rule y = k/x, where k is a constant number.
Given that y = 12 when x = 5, we can find the constant by multiplying x and y together, so: k = x * y = 12 * 5 = 60.
Now that we have our constant, we can find y when x = 3 by rearranging the formula to y = k / x which gives us: y = 60 / 3 = 20. So, when x is 3, y is 20.

What is a trapezoid?
The Trapezoid is a 4 sided polygon. Two sides of the shape are parallel to each other and they are termed as the bases of the trapezoid. The non-parallel sides are known as the legs or lateral sides of a trapezoid.
There are three types of trapezoids , and those are given below:
a) Isosceles Trapezoid
b) Scalene Trapezoid
c) Right Trapezoid
The area of the Trapezoid is given by
Area of Trapezoid = ( ( a + b ) h ) / 2
where , a = shorter base of trapezium
b = longer base of trapezium
h = height of trapezium
Given data ,
For a scalene trapezoid ,
The four sides are of unequal length
The angles of the scalene trapezoid are not equal
The shortest distance between two parallel sides is known as the altitude
The sides of the scalene trapezoid does not bisect each other
