Sean bought 1.8 pounds of gummy bears and 0.6 pounds of jelly beans and paid $10.26. He went back to the store the following wee

Ymorist [56]

Answer:

Gummy bears $3.20/lbs

Jelly beans $7.50/lbs

Step-by-step explanation:

For this we will substitute gummy bear price for "x" and jelly bean price for "y" which creates this system (also assuming there is no sales tax involved):

1.8x + 0.6y = 10.26

1.2x + 1.5y = 15.09

Then once solved, answers come out to be (x,y) = (16/5,15/2) which is (3.2,7.5)

Determine whether the improper integral converges or diverges, and find the value of each that converges.

Brrunno [24]

Answer:

Converges at -1

Step-by-step explanation:

The integral converges if the limit exists, if the limit does not exist or if the limit is infinity it diverges.

We will make use of integral by parts to determine:

let:

$u=x$ $dv=e^(2x)\cdot{dx}$

$du=dx$ $v=2\cdot{e^(2x)}$

$\int\limits^a_b {u} \, dv = uv -\int\limits^a_b {v} \, du$

$\int\limits^a_b {x\cdot{e^2^x} \, dx =2xe^2^x- \int\limits^a_b {2e^2^x} \, dx$

$\int\limits^a_b {xe^2^x} \, dx = 2xe^2^x-2e^2^x-C$

We can therefore determine that if x tends to 0 the limit is -1

$\lim_{x \to \0} 2xe^2^x-2e^2^x=0-1=-1$

Find length of each side

IgorLugansk [536]

Option b: 10 in, 18.5 in, 31.5 in.

Explanation:

The three sides of a triangle are $2y+1, 3y+5$ and $7y$

The perimeter of the triangle is $60 in$ .

Since, Perimeter = all sides of the triangle

Let us add all the three sides to determine the length of each side.

$Perimeter=2y+1+3y+5+7y$

Substituting the value of Perimeter and simplifying, we get,

$60=12y+6\\54=12y\\4.5=y$

Substituting $y=4.5$ in the three sides of the triangle $2y+1, 3y+5$ and $7y$ , we get,

$2y+1=2(4.5)+1=10 in$

$3y+5=3(4.5)+5=18.5 in$

$7y=7(4.5)=31.5 in$

Thus, the lengths of each side are 10 in, 18.5 in, 31.5 in.

hodyreva [135]

Answer:

Well I recently tore my meniscus a little bit, but you said yours popped/locked, I don't think mine did that. But it could be a bigger meniscus tear then mine, don't take my word for it tho, I'm no orthopedic or doctor. And for the second time in 7-9 months?? I'd definitely go get that checked out if you can.
