What is the range of F(x)=72x-x^2

Mathematics
1 answer:
Marianna [84]2 years ago
3 0

Answer:

Range of F(x) = (-∞ ,72).

Step-by-step explanation:

Range of the function F(x) means the set of values which are taken by the function along its domain.

F(x) = 72 - x^{2}

Since coefficient of x^{2} is negative on the right side ,

Maximum value of F(x) will come at x = 0.

Which is, F(0) = 72.

Now, as x increases , F(x) decreases , when x will reach infinity ,

F(x) will be reaching negative of infinity .

Thus, F(x) is ranging from -∞ to 72 .

Range of F(x) = (-∞ ,72).

Step-by-step explanation:

FULL QUESTION:

The highest scorer of the​ women's basketball championship was Jessica Bradley. She scored 149 more points than Tina​ Harner, her teammate.​ Together, Bradley and Harner scored 1563 points. How many points did each player score during the​ championship?

Let T = points scored by Tina Harner

     J = points scored by Tina Harner

She scored 149 more points than Tina​ Harner, her teammate.​ This means;

J = T + 149...........(i)

Together, Bradley and Harner scored 1563 points. This means;

J + T = 1563 .........(ii)

How many points did each player score during the​ championship?

We have to find T and J.

Substitute value of J from eqn (i) into eqn (ii)

T + 149 + T = 1563

2T = 1563 - 149 = 1414

T = 1414 / 2 = 707

J = 707 + 149 = 856

Jessica Bradley - 856 Points

Tina​ Harner - 707 Points

1 what is sum of the interior angles of ABCD what is the sum of the exterior angles of CHFE 3 which sides are parallel to CE 4 w
expeople1 [14]

Given that ABCD is a parallelogram, the sum of its interior angles is:
360°

<h3>What is a parallelogram?</h3>

A parallelogram is a rectilinear two-dimensional figure with four sides whose opposite sides are parallel. See the image attached.

<h3>What is the sum of the exterior angles of CHFE?</h3>

The sum of the exterior angles of any Triangle or any polygon is 360°. Hence, the sum of the exterior angles of CHFE (a polygon) is 360°.

<h3>Which sides are parallel to CE?</h3>

The sides that are parallel to CE are:

FH

AD and

<h3>IJ.

Which side is perpendicular to CE?</h3>

The side that are perpendicular to CE is side side HH, hence we can state that:

CE ⊥ EH, because both lines intersect each other at right angles.

<h3>What is the sum of ∠C and ∠H?</h3>

Because the sum of angles in a triangle is 180° and we already have ∠CEH to be equal to ∠90° hence,

∠C + ∠H? = 180° - 90°

= 90°

<h3>What is the measure of the exterior angles of a Regular Pentagon?</h3>

The measure of the exterior angles of a regular pentagon is 72°

Dima called her friend to tell her that she saved 30% on her new skirt at a discount store. Her friend told her that she could h
Olenka [21]
Since the rate of the other store is not given, let us just get the sales price of the skirt Dima bought from the discount store.

Original price : $54
Discount rate : 30%

$54 x 30% = $16.20 value of the discount
$54 - 16.20 = $37.80 discounted price.

Since Dima's friend told her she could have had a better deal at a different store, this means that the discount rate is higher than 30%. Let us assume that the discount is 35%

$54 x 35%  = $18.90 value of the discount
$54 - 18.90 = $35.10 discounted price.

Discount store: $37.80
Different store: $35.10

Different store sales price is cheaper by $2.70

wlad13 [49]

Answer:

f(n) = 16(0.5)ⁿ⁻¹

Step-by-step explanation:

Find f(1) for each option.

a) f(1) = 16(0.5)¹⁻¹ = 16

b) f(1) = 32(0.5)¹⁻¹ = 32

c) f(1) = 16(0.5)¹ = 8

d) f(1) = 32(0.5)¹⁺¹ = 8

Only the first option matches the table.
