(100 points;)The area of a right triangle is 39.6 in², and the base of the triangle is 12 inches.
Which of the following values is the height of the triangle?
303 in.
1.65 in.
6.6 in.
6.1 in.

Answer:

she has 12 - D quarters.

She has 24 (12-D) cents in quarters

Step-by-step explanation:

You know that the number of coins, and you know the number of dimes - even if the amount is a variable - you can find the amount of quarters with an equation.

If you knew that Lina had 6 dimes instead of D, you would say 12 - 6 and get the number of quarters. You can do the same thing here.

and If you know Lina has 6 quarters, you could find the amount of money in cents by multiplying 6 by 25. You can do that here too, but with variables and an equation.

Answer:

she has 12 - D quarters.

The value of the expression for x=3 is 51

Step-by-step explanation:

Evaluating expressions

To evaluate a given expression, we simply substitute the value of the variables and complete the operations.

The expression to evaluate is:

P=3(2+5x)

We will evaluate for x=3:

P=3(2+5*3)

The product must be done first:

P=3(2+15)=3*17=51

The value of the expression for x=3 is 51

Answer:

The original price of the toaster is 2000

Step-by-step explanation:

Given: Toaster price = 2240

VAT = 12%

VAT amount = ?(I'll include this one)

Assume the original price be x.

Let the original price be x

Then,  x + 12% of x = 2240

x+12/100x x = 2240
100x+12x/ 100= 2240

112x/100=2240

112x = 2240 x 100 ⇒ 224000

x = 224000/112

x = 2000.

So, the original price of toaster = Rs. 2000.

The VAT amount = 2240 - 2000 ⇒ Rs. 240.

The VAT amount is Rs. 240.

Answer: 225 tiles

Step-by-step explanation:

Side of tile = 20 cm = 0.2 m

Side of bathroom = 3 m

Area of tile = 0.04 m²

Area of bathroom = 9 m²

No. of tiles = Ar (bathroom) / Ar (tile)

= 9 / 0.04

= 9 x 25

= 225 tiles

Step-by-step explanation:

(g - f)(x)

= g(x) - f(x)

= log(x - 3) + 6 - ([tex]\sqrt[3]{12x+1}[/tex] + 4)

= log(x - 3) + 6 - [tex]\sqrt[3]{12x+1}[/tex] - 4 ← collect like terms

= log(x - 3) - [tex]\sqrt[3]{12x+1}[/tex] + 2

Value of the given function[tex](g-f)x = log(x-3)-\sqrt[3]{12x+1} +2[/tex].

" Function is defined as the relation between the given variables is such that every input has exactly one output each."

According to the question,

Given functions are,

[tex]f(x) = \sqrt[3]{12x+1} +4\\\\g(x) = log(x-3) +6[/tex]

Substitute the value in the function (g -f)x we get,

[tex](g-f)x = g(x) -f(x)[/tex]

             [tex]= log(x-3) + 6 -( \sqrt[3]{12x+1} +4)\\\\= log(x-3) + 6 -\sqrt[3]{12x+1} -4\\\\= log(x-3) -\sqrt[3]{12x+1} +2[/tex]

Hence, Option(B) is the correct answer.

======================================================

Explanation:

We can use the discriminant formula to determine how many (and what type of) roots we have. The term "root" is another word for "solution" or "x intercept". It's the x value that makes y = 0.

Any quadratic is of the form ax^2 + bx + c = 0

The discriminant formula is

d = b^2 - 4ac

which is found underneath the square root in the quadratic formula.

Here are the three possible outcomes

With all that in mind, let's find the discriminant of the first equation on the very left.

First we need to get it into standard form ax^2+bx+c = 0

5x^2 + 2 = 4x

5x^2 - 4x + 2 = 0

We see that

Computing the discriminant gets us...

d = b^2 - 4ac

d = (-4)^2 - 4(5)(2)

d = 16 - 40

d = -24

The actual discriminant value itself doesn't matter. All we care about is whether its positive, zero, or negative.

In this case, we get a negative discriminant. So this equation goes to the "no real solutions" column.

-------------------------

Let's move onto the next quadratic

3x^2 + 24x = -48

3x^2 + 24x + 48 = 0

a = 3, b = 24, c = 48

d = b^2 - 4ac

d = 24^2 - 4(3)(48)

d = 0

The discriminant of zero means this equation goes into the "exactly one real solution" category.

-------------------------

For the next equation, we don't need to use the discriminant formula here.

Notice that the right hand side is negative, but the left side is never negative because 3 is positive and (x+5)^2 is never negative. There is no way to have 3(x+5)^2 be negative if we let x be a real number only.

The equation 3(x+5)^2 = -2 goes into "no real solutions" pile.

-------------------------

For the last equation, we have

a = 4, b = -16, c = 0

So,

d = b^2 - 4ac

d = (-16)^2 - 4(4)(0)

d = 256

The result is a positive number, so we have two different solutions.

The discriminant is a perfect square which means we not only have real number solutions, but those solutions are rational numbers. This only works when a,b,c are rational as well.
