The amount he should pay for 5 pounds of mushrooms is $3.6
<u>Step-by-step explanation:</u>
Given data is that,
Bowser bought 6 pounds of mushrooms at a rate of $4.32
At the same rate, determining that how much he should pay for 5 pounds of mushrooms is given by the rate formula.
Rate = total cost / total number of mushrooms
Now, Rate = 4.32 / 6
Let us assume, the cost for 5 pounds as 'x' dollars.
Therefore, Rate = x / 5
<u>To find the value of x, compare both the rates :</u>
⇒ 4.32 / 6 = x / 5
bringing 5 to the left side of the equation,
⇒ (4.32×5) / 6 = x
⇒ x = 21.6 / 6
⇒ x = 3.6 dollars
The amount he should pay for 5 pounds of mushrooms is $3.6
That's going to depend a lot on what you want to "do" to it.
I'm going to assume that you want to find a number for 'x' that makes
the whole equation a true statement. Here's how I would do it:
<u> 5 ln(x) = 35</u>
Divide each side by 5: ln(x) = 35/5
ln(x) = 7
Raise 'e' to the power of each side: e^[ ln(x) ] = e⁷
But e^[ ln(x) ] is just 'x'. So x = e⁷ = <em>1,096.633...</em> (rounded)
That's the only number you can write in place of 'x'
and make the original equation true.
Answer:
A. 2 distinct roots.
Step-by-step explanation:
2x^2 + 8x + 3 = 0
Finding the discriminant:
b^2 - 4ac = 8^2 - 4 * 2 * 3
= 64 - 24
= 40
The discriminant is positive but not a perfect square
So there are 2 distinct ,real, irrational roots.
