Solve the quadratic equation. 1) 4x2 - 36 = 0

Answers

Answer 1

Step-by-step explanation:

welll i think tha answer is = 6-36 =0

= -30

Answer 2

Answer:

4x^2 - 36 = 0   ( Original equation )

4x^2 = 36        ( Add 36 to both sides )

x^2 = 9            ( Divide by 4 on both sides )

x = 3 , -3          ( Take the square root of 9 )

Solution set: { +3 , -3 } answer is x = +3 , x = -3

A right triangle has legs with lengths of 6in and 8in. What is the length of the hypotenuse

Answers

You require the Pythagorean Theorem: in a right triangle the sum of the squares of the legs equals the square of the hypotenuse.
In this case 6^2 + 8^2 = 36 + 64 = 100 = 10^2, i.e. the hypotenuse is 10.
Please note that a so-called 3-4-5 right triangle is the smallest right triangle which has integer sides...and of course, a 6-8-10 triangle like this one is simply a magnification of the smaller, i.e. a so-called similar triangle.

Answer: 10

Step-by-step explanation:

the formula is √a^2+b^2=c^2

so your equation should look like this √6^2+8^2=c^2

6·6=36

8·8=64

√36+64

√100=10

the hypotenuse or c^2 is 10

d. a number multiplied by seven then added to two

Answers

Answer:

D should be the correct answer:) hope this helps:))

The phrase represents the expression 7x + 2 is the number multiplied by seven then added to two, So Option D is correct

What are expressions?

An expression is a sentence with at least two numbers or variables having mathematical operation. Math operations can be addition, subtraction, multiplication, division.

For example, 2x+3

Given that,

An expression,7x + 2

here, 7 is coefficient

x is variable

And then in 7x, constant number 2 is added

So it can be state that a number multiplied by seven then added to two

So, the statement is 7  multiplied in number then 2 is added

MODELING REAL LIFE The table shows the profit y for recycling x pounds of aluminum. Find the profit for recycling 75 pounds of aluminum. Aluminum (lb), x 10 20 30 40 Profit, y $4.50 $9.00 $13.50 $18.00​

Answers

Answer: 33.75

Step-by-step explanation:

It’s right

There is a profit of $33.75 for recycling 75 pounds of aluminum.

What is Function?

A function is a relation from a set to another set such that element in the first set only maps to one element in the other set.

A function f from a set A to a set B can be represented as f : A → B

We have,

Profit for recycling 10 lb Aluminum = 10/10 × 4.5 = 4.50

Profit for recycling 20 lb Aluminum = 20/10 × 4.5 = 9.00

and so on

Therefore, we can write this as a function.

f(x) = [tex]\frac{x}{10}[/tex] × 4.5

We have to find the profit for recycling 75 pounds of aluminum.

f(75) =  [tex]\frac{75}{10}[/tex] × 4.5

       = 7.5 × 4.5

       = 33.75

Hence the profit for recycling 75 pounds of aluminum is $33.75.

Jenny selects a box of cereal for her family at the supermarket. Across town, Chase also happens to pick out a box of cereal for his own family. Are these two events dependent or independent?

Answers

Answer:

Independent

Step-by-step explanation:

In clear and simple terms, Events A and B are sid to be independent if the occurrence of event A and event B can occur simultaneously, that is the occurrence of A does not affect or stop the occurrence of B at the time.

The events being compared can happen concurrently with Jenny and chase both making selection for their respective families. However, events which cannot occur together are called mutually exclusive events such as obtaining a head and tail from a single coin toss, this events cannot happen together and are thus not independent.

Noah wrote that 6 + 6 = 12. Then he wrote that 6 + 6 - n = 12-n. Select the phrases that make the statement true

Answers

Answer:

6 +6 =12

Step-by-step explanation:

it is telling you that the statement is true because the next equation says 6 +6 -n and the first equation helps you know the answer is true because you know that n is being taken away from the answer which is 12.

hope that helps and makes sense

The equations are balanced because Noah subtracted the same number on each side of the origin.

What is Algebra?

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

Equation property: If a number is subtracted, added, multiplied, or divide into both sides of the equation, then the equation remains balanced.

Noah wrote that 6 + 6 = 12.

Then Noah subtracted n from both sides of the equation. Then the equation will be

Then he wrote that 6 + 6 - n = 12-n.
