We will see that the exponential decay function is:

f(x) = 175*(0.8)^x

The general exponential decay is:

f(x) = A*(1- r)^x

Where:

Here we know that the initial value is 175, and the rate of decay is 20%. To get this in decimal form, we just divide it by 100%.

20%/100%  = 0.2

Replacing that in the exponential function, we get:

f(x) = 175*(1 - 0.2)^x

f(x) = 175*(0.8)^x

ANSWER:

y=2x-3

HOPE IT HELPS

Step-by-step explanation:

Add the system of equations each one by one.

I added them all downwards until i found the 4th one to be correct

y = 2x - 3

y = 2x - 3

--------------

2y = 4x - 6

y = 2x - 3.

To find the value of y in each coordinates given above, substitute their respective x values.

1......y = 2(5) - 3

= 10 - 3

= 7.

2......y = 2(8) - 3

= 16 - 3

= 13.

then write the value you substituted in x on the left side of each bracket & the value you got when you substituted them on the right.

The average rate of change for the quadratic function x²+2x+3 from x=−2 to x = 5 is 5.

A slope is also known as the gradient of a line or the average rate of change of a number that helps to know both the direction and the steepness of the line.

The rate of change of any function is the slope of the function, therefore, the slope of the function is written as,

[tex]m = \dfrac{y_2 - y_1}{x_2-x_1}[/tex]

As the value of the y is the function of the x, while the value of x is given, therefore,

[tex]x_2 = 5\\x_1=-2\\\\[/tex]

Now, the value of y,

[tex]y_2 = f(5) = x^2 +2x+3 = (5)^2+2(5)+3 = 38\\y_1 = f(-2) = x^2 +2x+3 = (-2)^2+2(-2)+3 = 3[/tex]

Substituting the value of x and y in the formula of the slope, we can write the slope as,

[tex]m = \dfrac{y_2-y_1}{x_2-x_1}\\\\m = \dfrac{f(x=5) - f(x=-2)}{5-(-2)}\\\\m = \dfrac{38-3}{7}\\\\m= 5[/tex]

Hence, the average rate of change for the quadratic function x²+2x+3 from x=−2 to x = 5 is 5.

Answer:

Freezer A is a better buy in terms of dollars per cubic​ foot.

Step-by-step explanation:

Freezer A: V = 2*2*4 = 16 ft^3

P/V= 400/16 = 25 $/ft^3

Freezer B: V = 2.5*2.5*3 = 18.75 ft^3

P/V= 500/18.75 = 26.6 $/ft^3

--> 25 < 26.6 that mean Freezer A is cheaper per cubic​ foot.

Answer:

∠ 2 = 160° , ∠ 3 = 10°

Step-by-step explanation:

The opposite angles of a rhombus are congruent , then

∠ 2 = ∠ 1 = 160°

The triangle has 2 congruent sides and is isosceles with base angles being congruent , then

∠ 3 = [tex]\frac{180-160}{2}[/tex] = [tex]\frac{20}{2}[/tex] = 10°

Answer:

m∠3 = 10° || m∠2 = 160°

Step-by-step explanation:

if  m∠1 =  160°

then m∠2 = 160°

The triangle is isosceles.

therefore

m∠3 + m∠3 + 160° = 180°

2 m∠3 = 180° - 160°

2 m∠3 = 20°

m∠3 = 10°

Answer:

  155°

Step-by-step explanation:

The obtuse angle of the large (outside) triangle is the supplement of 60°, so is ...

  180° -60° = 120°

The angle x is the sum of the remote interior angles of that large triangle:

  x = 35° +120° = 155°

__

Check

The other acute angle in the smaller (left) right triangle is 90° -35° = 55°. Then the top acute angle in the larger (bottom, right) right triangle is ...

  180° -55° -60° = 65°

The other acute angle in that triangle is 90° -65° = 25°. It is supplementary to angle x. Hence angle x is 180° -25° = 155°, as above. (Note that x is also the sum of 90° and 65°, the remote interior angles of the nearest right triangle to x.)

Answer:

He walks 10kph.

Steps:

So he walks 1km every 0.1 hour,

1 * 10 = 10

     ^

(which is 1.0 hour)

Answer:

10 km/h

Step-by-step explanation:

Speed = rate at which the man walks

= distance travelled/ time taken to travel the distance.

Speed = distance/time

= 7/0.7

= 70/7

= 10 km/h

Therefore, he walks at a speed of 10 km/h

Answer:21,000

Step-by-step explanation:

350,000 ×6/100 = 350,000×0.00.06 =21,000

The commission earned by the agent is $21,000 which is the 6% of the total selling price.

Percentage is defined as the parts of a number per fraction of 100.  So the percentage actually means a part per 100.

Percentage is usually denoted by the symbol '%'.

We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.

Given that,

Price for which the home is sold = $350,000

Percentage as commission earned by real estate agent = 6%

Amount of commission = 6% of $350,000

                                       = 6% × 350,000

                                       = (6/100) × 350,000

                                       = 0.06 × 350,000

                                       = $21,000

Hence the commission earned by the real estate agent is $21,000.
