Question

Solve for y where x equals fraction numerator square root of y minus 14.2 end root over denominator 0.05 end fraction

hintHint:

Rearrange the equation and then solve for y.

The correct answer is: not stretchy rightwards double arrow y equals 2.5 cross times 10 to the power of negative 3 end exponent x squared plus 14.2


    Complete step by step solution:
    Here we have the equation x equals fraction numerator square root of y minus 14.2 end root over denominator 0.05 end fraction
    On multiplying both the sides by 0.05, we have 0.05 x equals square root of y minus 14.2 end root
    On squaring both the sides, we have left parenthesis 0.05 x right parenthesis squared equals left parenthesis square root of y minus 14.2 end root right parenthesis squared

    not stretchy rightwards double arrow 2.5 cross times 10 to the power of negative 3 end exponent x squared equals y minus 14.2
    On adding 14.2 on both the sides, we get 2.5 cross times 10 to the power of negative 3 end exponent x squared plus 14.2 equals y
    not stretchy rightwards double arrow y equals 2.5 cross times 10 to the power of negative 3 end exponent x squared plus 14.2

    Tavon has a $50 gift card that loses $2 for each 30 day period it is not used . He has $40 card that loses $1.50 for each 30 day period it is not used .
    Write and solve an equation for the number of 30 day periods until the value of the gift cards will be equal ?

    The quantity of goods in general that will be exchanged for one unit of money is then the value of money. Money's value is defined as its purchasing power, or the amount of goods and services it can buy.
    The time value of money (TVM) is the idea that a sum of money is worth more now than it will be at a later date because of the potential earnings in the interim. A sum of money in hand is more valuable than the same sum to be paid later. The time value of money is another name for the present discounted value.

    The triangle shown is isosceles. Find the length of each side and the perimeter ?

    An isosceles triangle is one with two sides of the same length. An isosceles triangle's two opposite angles are equal in size.
    ¶Triangles are three-sided polygons that are classified into three types based on their sides, such as:
    ¶Triangle of Scalene (All three sides are unequal)
    Triangle of isosceles (Only two sides are equal)
    (All three sides are equal) Equilateral triangle
    ¶Triangle's isosceles perimeter in units of P = 2a + b
    ¶The area of an isosceles triangle
    A = 1/2 x b x h Square units.
