<u>Answer </u>

B. f(x) = - (y/x)⁵

<u>Explanation</u>
A negative power means the reciprocal of that number raised to the positive value .
For example, a⁻ⁿ = 1/aⁿ

So, for the question above.
f(x) = -(x/y)⁻⁵
      = - 1/(x/y)⁵
      = - (y/x)⁵

The answer for the problem shown in the figure attached, is the option B, which is:
 B) f(x)=(-y/x)^5
 The explanatio for the exercise is shown below:
 1. You have the following function given in the problem above:
 f(x)=-(x/y)^-5
 2. The negative exponent -5, indicates that the x must be in the denominator and the y must be in the numerator, and the exponent must be positive as following: 
 f(x)=(-y/x)^5

Need help with this math question!!!!!!!!!
exis [7]

ANSWER

The vertex is (1,-3)

EXPLANATION

The given parabola has equation:

{y}^{2}  + 6y + 8x + 1 = 0

We group the variables to obtain:

{y}^{2}  + 6y  =  -  8x -  1

We complete the square to get,

{y}^{2}  + 6y  +  {3}^{2}  =  -  8x -  1 +  {3}^{2}

{(y+ 3)}^{2}  =  -  8x +8

{(y+ 3)}^{2}  =  -  8(x  -1)

The vertex is of the parabola is (1,-3)

Drag a figure into each blank space so that the two figures in the row match the description.
LekaFEV [45]

Answer:

i) not similar but corresponding angles have equal measures.

  the blue object required to be dragged to the box is the fourth object which is a square. A square will not have proportional lengths and is not similar to the given figure but the corresponding angles will have equal measures.

ii) not similar but side lengths are proportional.

the blue object required to be dragged to the box is the first object which is a parallelogram. A parallelogram will have proportional lengths and is not similar to the given figure because the corresponding angles do not have equal measures.

Step-by-step explanation:

i) not similar but corresponding angles have equal measures.

Pleasee help!! “It costs $2.75 to buy 3/4 lb of grapes. How much would it cost to purchase 9.5 lbs of grapes? Explain or show yo
avanturin [10]

Answer:

$34.83

Step-by-step explanation:

First convert 3/4 to decimal form: 3/4 = 0.75

Create a proportion using similar rates:

$2.75 / 0.75 lb  = x / 9.5 lb

where "x" represents the price of the 9.5 lbs of grapes we need to find.

Solve for x by multiplying both sides by 9.5 lb to isolate x completely

2.75 * 9.5 / 0.75 = x

Therefore x = $34.83
