write any two quadratic equations​.

Answers

Answer 1

To find:

Any two quadratic equations​.

Solution:

The general form of a quadratic equation is:

[tex]ax^2+bx+c=0[/tex]

Where, a,b and c are real number and a is non zero.

We know that a,b,c can take any values but a cannot be 0.

For a=1, b=1,c=1, we get

[tex]1x^2+1x+1=0[/tex]

[tex]x^2+x+1=0[/tex]

One quadratic equation is [tex]x^2+x+1=0[/tex].

For a=3,b=-1,c=5, we get

[tex]3x^2+(-1)x+5=0[/tex]

[tex]3x^2-x+5=0[/tex]

Therefore, the two quadratic equations are [tex]x^2+x+1=0[/tex] and [tex]3x^2-x+5=0[/tex].

Calculate the size of the missing sides and angles.

Answers

Answer:

large triangle:

base = 6.64 cm

hypotenuse = 8.31 cm

small triangle:

base = 4 cm

Step-by-step explanation:

large triangle:

tan 37 = 5/base

0.7536 = 5/base

base = 6.64 cm

using the Pythagorean theorem:

hypotenuse² = 5² + 6.64²

hypotenuse² = 25 = 44.02 = 69.02

hypotenuse = 8.31 cm

small triangle:

using the Pythagorean theorem:

base² = 5² - 3²

base² = 25 - 9 = 16

base = 4 cm

What interval consists of all $u$ such that neither $2u$ nor $-20u$ is in the interval $(-\infty,-1)$ ?

Answers

Answer:

[-1/2,1/20]

Step-by-step explanation:

Answer:

[-1/2,1/20]

Step-by-step explanation:

In terms of inequalities, we are asked to find all $u$ such that $2u\ge -1$ and $-20u\ge -1$.

The solution to the first inequality, obtained by dividing both sides by $2$, is $u\ge -\frac{1}{2}$.

We can solve the second inequality by dividing both sides by $-20$, but because we are dividing by a negative number, we must reverse the direction of the inequality: $u\le \frac{1}{20}$.

The set of $u$ which satisfy both inequalities simultaneously is thus $\boxed{\left[-\frac{1}{2},\frac{1}{20}\right]}$.

Adam can buy pencils in packages of 12 for $2.19, 40 for $3.99, 50 for $4.75, or 100 for $10. How many pencils are in the package with the lowest unit cost

Answers

Answer:

50 pencils

Step-by-step explanation:

2.19/12 = .18

3.99/40 = .09975

4.75/50 = .095

10/100 = .10

Although with mark-up to the hundredths place, there wouldn't be a logical difference is stores...

Answer:

50 for $4.75

Step-by-step explanation:

First step is to determine the unit cost of each pencil:

price of pack / number of units = cost per pencil

1. $2.19 / 12 = $0.1825

2. $3.99 / 40 = $0.09975

3. $4.75/ 50 = $0.095

4. $10 / 100 = $0.10

The correct answer is $4.75 for 50 pencils because it is the lowest per unit cost.
