The exponential function is given by y = 0.9(1.082)ˣ

An exponential function is in the form:

y = abˣ

where y, x are variables, a is the initial value of y and b is the multiplier.

Let y represent the fish weights at x inches.

Using point (4, 1.24):

1.24 = ab⁴   (1)

Using point (10, 1.99):

1.99 = ab¹⁰  (2)

From equation 1 and 2:

b = 1.082, a = 0.9

The exponential function is given by y = 0.9(1.082)ˣ

Answer:

c.14

Step-by-step explanation:

Answer:

14

Step-by-step explanation:

To get the Greates Common Factor (GCF) of 238 and 462 we need to factor each value first and then we choose all the copies of factors and multiply them:

238:    2   7

462:    2 3 7

GCF:    2   7    

The Greates Common Factor (GCF) is:   2 x 7 = 14

1. Observe the problem

2. Make a system of linear equations

x is pens

y is pencil

As stated in the text, x=2y

x=2y

7x+12y=6.50

Using substitution,

7(2y)+12y=6.50

14y+12y=6.50

26y=6.50

y=0.25

Substituting it back into the first equation:

x=2(0.25)

Answer:

112%

Step-by-step explanation:

percentage change value formula

c2 =  X2  -  X 1       X   100

             X1                   1

WHERE,

C2 = RELATIVE VALUE

X2  = FINAL VALUE  ( TODAY'S VALUE)  = 32,860

X1 = INITIAL VALUE  (1992 VALUE) = 15,500

PERCENTAGE CHANGE = 100

C2 =   32860  -   15500   X   100

                 15500                    1

=    17, 360       X 100

     15,500                 = 1.12 X 100 = 112%.

Answer: C. y= 75x + 200

Step-by-step explanation:

Since they charge $75 an hour x represents the house and they charge an initial fee of $200 so you add that to the $75 an hour

Answer:

C

Step-by-step explanation:

The equation y  = mx + b helps use to solve this type of problem

We know the initial amount to rent the gym is $200, that will be our b for this case since it is the y-intercept. This is the y-intercept since that is the initial amount.

The slope for this equation will be 200 represented by m. The key term that represents this is out slope is per. "$75 per hour." Since the function is in hours we don't need to convert hours into another unit.

Now if we plug in the variables, we get the equation y = 75x + 200 which is what C is.

Answer: Yes

Step-by-step explanation:

Yes, since the square root of an integer (which is a real number), is a real number.

Answer:

y=x+2

y=x+4

slope intercept form is y=mx+b

Answer:34

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

Here [ a, b ] = [ 1, 6 ], thus

f(b) = f(6) = 6³ - 9(6) = 216 - 54 = 162

f(a) = f(1) = 1³ - 9(1) = 1 - 9 = - 8

average rate of change =  =  = 34

Answer:

Rs. 612,480

Step-by-step explanation:

Hi there,

Here the question asks us to find the cost of leveling a badminton court at the rate of Rs.80 per sq..

So by the word leveling we know that we have to find the area of the court in order to proceed further.

(I am assuming the court to be rectangular in shape).

Area of a rectangle = Length * Breadth

*Length = 132 meters

*Breadth = 58 meters

==> 132*58= 7656 m^2

So now that we got the area of the badminton court lets find the cost of leveling it ==>

Cost of leveling per meter^2 = Rs. 80

Area = 7656 m^2

==> 7656 * 80 = 612,480

So the cost would be Rs. 612,480

Answer:

D) 53°

Step-by-step explanation:

Angles AEB and BEC are supplementary.

Step 1: Subtract 127 from both sides.

Therefore, the answer is 53°.[tex]x+127-127=180-127[/tex]

Answer:

  U = 126°

Step-by-step explanation:

Assuming the figure is a parallelogram, opposite angles are congruent, and adjacent angles are supplementary.

  V = T

  10x -6 = 8x +6 . . . . substitute for V and T

  2x = 12 . . . . . . . . . add 6-8x

  x = 6 . . . . . . . . . divide by 2

Then V = 10(6)-6 = 54, and U is ...

  U = 180° -54°

  U = 126°
