Investment A 50 increases each year by 8% investment B 60 increases by 3 each year what year will investment A be bigger than be
UkoKoshka [18]

Answer:

After 10 years the investment A will be bigger than investment B.

Step-by-step explanation:

In Investment A, 50 increases each year by 8% and in investment B, 60 increases by 3 each year.

If after x years the investment A will be equal to investment B, then we can write the equation as

50(1 + \frac{8 \times x}{100}) = 60 + 3x

⇒ 50 + 4x = 60 + 3x

⇒ x = 10

Therefore, after 10 years the investment A will be bigger than investment B. (Answer)

p is the point on the line 2x+y-10=0 such that the length of OP, the line segment from the origin o to p is a minimum. find the
REY [17]
Coolio

alright, so the disatnce formula is
D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

solve for y in the equation given on top
2x+y-10=0
y=10-2x
ok
so (x1,y1)=(0,0), the first point
(x2,y2)=(x,10-2x)
so subsitute to get

D=\sqrt{(x-0)^2+(10-2x-0)^2}
D=\sqrt{(x)^2+(10-2x)^2}
D=\sqrt{x^2+4x^2-40x+100}
D=\sqrt{5x^2-40x+100}
find the miniumum
we only need to minimize what is under the square root so
take the derivitive of 5x²-40x+100
that is 10x-40
it is 0 at x=4
when x<4, the derivitive is negative
when x>4, the derivitive is positve
goes from negative to positive
so it is a minimum

at x=4
find y
y=10-2x
y=10-2(4)
y=10-8
y=2

(4,2)
find min distance

D=\sqrt{(x-0)^2+(y-0)^2}
D=\sqrt{(4-0)^2+(2-0)^2}
D=\sqrt{(4)^2+(2)^2}
D=\sqrt{16+4}
D=\sqrt{20}
D=2\sqrt{5}



the point, P, is (4,2) and the minimum distance is 2√5

Eliah bought 1.87 pounds of chicken and 2.46 pounds of turkey at the deli. About how many pounds of meat did he buy?
mart [117]
So,

If this was mental math, I would round 1.87 to the nearest pound and 2.46 to the nearest half pound, making the following addition problem:
2 + 2.5 = 4.5
Because 1.87 is closer to 2 than to 1.5 or 1, and 2.46 is sooo close to 2.5.
So I would say about 4.5 pounds of meat.

But if you're rounding to the nearest pound for both, then you have this equation:
2 + 2 = 4
Because in 1.87, 8 is greater than or equal to 5, and in 2.46, 4 is less than or equal to 5.
So in that case, it would be about 4 pounds of meat.
