Find the dimension of a rectangle whose with is 6 miles less than its length and whose area is 72 square tiles

Answers

Answer:

Length = 12

Width = 6

Step-by-step explanation:

Width = 6 miles less than length;

L = L

W = L - 6

Area = 72 ft²

Area = Length * width

Area = (L * L-6)

Area = L² - 6L

-

L² - 6L = 72

L² - 6L - 72 = 0

L² - 12L + 6L - 72 = 0

L(L - 12) +6(L - 12) = 0

L = 12 or L = - 6

L cannot be negative

Width = L - 6

Width = 12 - 6 = 6

Hence,

Dimension of rectangle :

Length = 12

Width = 6

Your mom sends you to the store to buy some meat for
your birthday party.
She gives you $65 and wants you to spend it all on
exactly 15 pounds of meat.
Chicken is $3 a pound.
Steak is $5 a pound.
Is her request possible? If so, how much of each meat
would satisfy your mom's request?

Answers

Step-by-step explanation:

10 pounds of steak for 5 dollars each = $50

$65 - $50 = $15

5 pounds of chicken for 3 dollars each = $15

$15 - $15 = 0 10 pounds + 5 pounds = 15 pounds

Answer:Yes

Step-by-step explanation:

If you want to buy 13 pounds of steak then you spend all of your money

Evaluate f(x)=7x+7 when x=-9

Answers

Answer:

-56

Step-by-step explanation:

f(x) = 7x + 7

x = -9

We meed to plug in x = -9 into the first equation:

f(-9) = 7(-9) + 7

We can open up the parentheses:

f(-9) = -63 + 7

And then simplify:

f(-9) = -56

True of flase a point (0,2) can be reflected across the x-axis PLEASE HELP 50 POINTS​

Answers

Answer:

The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same. For example, when point P with coordinates (5,4) is reflecting across the X axis and mapped onto point P', the coordinates of P' are (5,-4).

So what do you think the answer is true or false

Answer:

True

Step-by-step explanation:

That is possible since the x is on 0. It can flip and then it lands on (0,-2) I think.

A parabola has a vertex at (0,0). The focus of the parabola is located at (4,0). What is the equation of the directrix? x=−4 y=−4 x=4 y=4

Answers

The equation of directrix of the parabola will be x = -4.

What is directrix ?

Directrix is a straight line distance to which from any point of a conic section is in fixed ratio to the distance from the same point to a focus. The directrix is perpendicular to the axis of symmetry and does not touch the parabola.

We have,

Vertex of parabola = (0, 0),

Focus of the parabola = (4, 0),

Now,

The Equation of directrix is given by y = -a

Where,

The equation of the parabola, [tex]y^2 = 4ax[/tex],

And,

Focus at (a, 0),

i.e. a = 4    (As the given focus is (4, 0))

And,

The axis of the parabola is the positive x − axis.

So,

The equation of the directrix of this parabola,

x + a = 0,

i.e.

x + 4 = 0

⇒

x = -4

Hence, we can say that the equation of directrix of the parabola will be x = -4.

A new savings account is opened with 400 and gains 3% every year.what is the exponential function?

Answers

Answer:

Exponential function is:

y = 100 (1.03)ˣ

Step-by-step explanation:

We know that the exponential growth function is of the form

y = a (1 + r)ˣ

Here:

a = initial value

r = growth rate

x = number of time intervals that have passed

Given that A new savings account is opened with 400. Thus,

a = 400

Given that a new saving account gains 3% every year.

r = 3% = 0.03

now substituting a = 400 and r = 0.03 in the function

y = a (1 + r)ˣ

y = 100 (1 + 0.03)ˣ

y = 100 (1.03)ˣ

Therefore, exponential function is:

y = 100 (1.03)ˣ

Please note that the growth factor i.e. 1.03 is greater than 1, so the exponential function represents exponential growth.

The graph shown below represents a ladder leaning against wall the bottom of the latter is 4 feet from the wall in the top of the ladder reach is 20 feet above the ground what is the slope of graph (I’m so sorry I don’t have a picture)

Answers

Hi I’m trying but yeeeeah

Answer:

C.) -5

Step-by-step explanation:

The slope formula is rise/run, in other words, rise divided by run or the y variable divided by the corresponding x variable.

In this question, we are told that the y-value is "20 feet above" meaning this is the rise and the run is "4 feet from"

To find the slope all we have to do is divide 20 by 4 giving us 5. Since the ladder is going down we know that we have to place a negative sign before the slope giving us our final answer of -5
