Answer:
$5.40
Step-by-step explanation:
The word <em>percent</em> literally means "for each 100," and we can use this vocab fact to help us answer a question like "what is 1.8 <em>percent </em>of $300?" We have 1.8 <em>for each 100</em> in 300, and since there are 3 hundreds in 300, that means we're going to be counting 3 1.8s, which gets us 1.8 × 3 = 5.4. Since our unit is <em>dollars</em> this comes out to $5.40.
Answer:
The number would have to be added is 2
Step-by-step explanation:
To find the form of the completing square of the quadratic function:
- Divide the coefficient of x by 2
- Subtract the numerical term from the square of the quotient
Let us do these steps with our question
∵ x² - 2x - 1 = 0
→ Divide the coefficient of x by 2
∵ The coefficient of x is -2
∴ -2 ÷ 2 = -1
→ Square the -1
∵ (-1)² = 1
→ Subtract the numerical term from 1
∵ The numerical term = -1
∵ 1 - (-1) = 1 + 1 = 2
∴ We must add 2 to -1 to get 1
→ (x² - 2x - 1 + 2) - 2 = 0
→ (x² - 2x + 1) = 2
→ (x - 1)² = 2
The number would have to be added is 2
Answer:
You call an expression with a single term a monimial, an expression with two terms is a binomial and an expression with three terms is a trinomial. An expression with more than three terms is named simply by it's number of terms. For example a polynomial with five terms is called a five-term polynomial.
