About what point on parabola y=x^2 is 5 units away from the origin along the curve
konstantin123 [22]

the distance from the origin is 5, so

sqrt(x²+y²)=5

x²+y²=25

substitue y=x²

y+y²=25

y²+y-25=0

solve using calculator or the formula

to get

y =( -1+sqrt(1+4*25))/2

or y = (-1-sqrt(1+4*25))/2

the second solution is rejected because a square cannot be negative

the value of x is the positive or negative (sqrt... or -sqrt...) or y

BIG POINTS
Savatey [412]
Let x be the amount invested at 7% and y the amount invested at 6%


We know that the yearly interest earned = 0.07(x) and 0.06(y)

x+y =4500

0.07x +0.06 y =290

Solving the equations will give , x = $2,000 and y=$2,500

Natsano has at most $55,000 to invest in the common stocks of two companies. He estimates that an investment in Company A will y
Aleks [24]

Answer:

  • A: $37500
  • B: $17500

Step-by-step explanation:

Natsano can satisfy his constraints by investing the first $20,000 in Company A, then splitting the remaining $35,000 evenly between the companies. For best return, he needs to invest as much as possible in Company B, but each such dollar (after the first 20k) must be matched by a dollar invested in Company A. That is, his investments should be ...

  • Company A: $37,500
  • Company B: $17,500

_____

The attached graph shows the feasible region of investments (doubly shaded). The vertex that maximizes the objective function (return on investment) is the one highlighted. (It puts the objective function line as far as possible from the origin.)

_____

Sometimes graphing the constraints is more work than necessary if there is some simple logic that quickly identifies the solution.

What is the product of Three-fourths and Negative StartFraction 6 over 7 EndFraction? -9/14
Brums [2.3K]

Answer:

The product is :  -\frac{9}{14}

Step-by-step explanation:

First term given to us is =  \frac{3}{4}

Second term given to us = -\frac{6}{7}

We have to find product for term 1 and term 2

Which means that we have to find : (\frac{3}{4})\cdot(-\frac{6}{7})

Calculating the product of fraction is pretty simple. To calculate the product of any two fractions. We have to multiple the numerator of 1st term with numerator of 2nd which serves as the the numerator of the product. Similarly we have to multiply denominator with denominator.

(\frac{3}{4})\cdot(-\frac{6}{7}) = \frac{3\cdot(-6)}{4\cdot7} = -\frac{18}{28}

Reduce the fraction

-\frac{18}{28}= -\frac{9}{14}
