Step-by-step explanation:
So we know that for 12 rock cakes we need 225g flour and 75g sugar to get 42 rock cakes we need to multiply the number of ingredients by 3.5 (42/12 =3.5)
This gets us 787.5 g flour and 262.5 g sugar.
Show work:
Nishat has enough flour and sugar to make 42 rock cakes.
Answer:
a = 4, x = 1
Step-by-step explanation:
The opposite sides of a parallelogram are congruent , then
WX = YZ , that is
a² + 5a = 5a + 16 ( subtract 5a from both sides )
a² = 16 ( take the square root of both sides )
a = ± = ± 4
Since a > 0 , then a = 4
Also
XY = WZ , that is
x² + 6x = 4x + 3 ( subtract 4x + 3 from both sides )
x² + 2x - 3 = 0 ← in standard form
(x + 3)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 1 = 0 ⇒ x = 1
Since x > 0 , then x = 1
<u>Answer-</u>
<em>Equation 1</em><em> is the equation which represents the graph.</em>
<u>Solution-</u>
From the graph it can be noticed that, the function is a hyperbola. It is a rectangular hyperbola.
The general form of rectangular hyperbola is,
Where c is a constant.
Equation 1 represents a function of rectangular hyperbola, with vertical asymptote as x=-2 .
Equation 2 represents an exponential function.
Equation 2 represents an cubic function.
Equation 2 represents logarithmic function.
Therefore, equation 1 is the equation which represents the graph.
