Use the discriminant to find all values of b for which the question has one real solution.

Arada [10]

Use the formula 0 = b^2-4ac

0 = -b^2-4(2)(-9)

0 = -b^2+72

b^2 = 72

b = square root of 72

b = 2 real numbers

40 kg of tomatoes cost $200 how many kilograms of tomato’s can you get with $45

Roman55 [17]

Answer:

9 kg of tomatoes

Step-by-step explanation:

Cost of 40 kg of tomatoes = $200

Cost of 1 kg of tomatoes = 200/40 = $5

For $45, we get x kg of tomatoes,

kg $

1 5

x 45

=> 45*1/5 = x kg (by cross multiplication)

=> 45/5 = x kg

We get 9 kg of tomatoes for $45.

Hope you understood!

Explain how you can find the side length of a rectangular prism if you are given the volume and the 2 other measurements. Does t

Andreyy89

Answer:

The volume of a rectangular prism can be calculated by the formula:

Volume of a rectangular prism = length * width * height

If the exercise give us the volume and the two other measurements (width and height), we must simplify the length from the formula showed (remember when a value is multiplying in a side to the equal sign, go to the other side to divide):

(Volume of a rectangular prism) / (width * height) = length

Or, in other form:

$length=\frac{volume}{width*height}$

At last, the proccess change only a little if one is a fraction, in that case, you should just multiply or divide with that fraction.

Step-by-step explanation:

We're gonna take measurements for the volume, width and height to solve a hypothetical exercise:

Volume = 240 $in^{3}$
Width = 4 in
Height = 12 in

We use the formula in the answer:

$length=\frac{volume}{width*height}$

Replacing the data we obtain:

$length=\frac{240in^{3} }{4 in *12in }$
$length=\frac{240in^{3} }{48in^{2} }$
$length=$ 5 inches

Now, we're gonna make the a hypothetical exercise where a measurement is a fraction, we can select anyone, in this case will be the width:

Volume = 48 $in^{3}$
Width = 8/3 in
Height = 6 in

We use the same formula and replace again:

$length=\frac{volume}{width*height}$

$length=\frac{48in^{3} }{\frac{8}{3}in *6 in}$
$length=\frac{48in^{3} }{16in^{2} }$
$length=$ 3 inches

As you can see, the process does't change much using fractions, you must only know the correct form to operate these.
