The greater of two consecutive integers is seven less than one-third the smaller integer. Find the integers
ikadub [295]

Answer:

Step-by-step explanation:consecutive integers are represented by x, x+1 ,  so for this problem the greater one is represented by x + 1.

Now you need to translate the problem.  the greater is  seven less than 1/3 the smaller

--->  x + 1 = (1/3)*x - 7 --->  now solve for x (the smaller) and x+1  (the greater)

***hint:  to get rid of fractions in an equation you can always multiply EVERYTHING by the denominator , 3 in this case

35. Two variables, x and y, appear to be exponentially related. The regression equation for ln y on x is ln y = 1.7 + .45x. What
GrogVix [38]

Answer:

y=7.57

Step-by-step explanation:

Two variables, x and y, appear to be exponentially related. The regression equation for ln y on x is ln y = 1.7 + .45x

we need to predict the value of y when x=0.72

plug in the value of x in the given equation

ln y = 1.7 + .45x

ln y = 1.7 + .45(0.72)

ln y = 1.7 + 0.324

ln y = 2.024

y=e^{2.024}

y=7.57

What is the general equation of a sine function with an amplitude of 6, a period of startfraction pi over 4 endfraction, and a h
natta225 [31]

Answer:

  f(x) = 6·sin(8(x -π/2))

Step-by-step explanation:

A transformed sine function with amplitude A, period P, and horizontal shift S can be written as ...

  f(x) = A·sin(2π/P(x -S))

__

The equation for A=6, P=π/4, and S=π/2 is then ...

  f(x) = 6·sin(8(x -π/2))

_____

<em>Additional comment</em>

The horizontal shift is equal to two full periods, so the shifted function is indistinguishable from the unshifted function.
