Formula for area of a rectangle is: A = l x w
A: Area
l: length
w: width

length of football field is 100 yards and width is 53.3 yards.
To find the area we need to multiply the length by width.

Area of football field = 100 x 53.3 = 5330 square yards (yards^2)

A father's age now is three times the age that his son was four years ago. In 12 years, the father will be twice as old as his s

irina1246 [14]

Answer:

Now, the father is 60, and the son is 24.

Step-by-step explanation:

Now:

Father's age = f

Son's age = s

4 years ago:

Father's age = f - 4

Son's age = s - 4

In 12 years:

Father's age = f + 12

Son's age = s + 12

Now:

f = 3(s - 4)

In 12 years:

f + 12 = 2(s + 12)

We have 2 equations that we can solve in a system of equations.

f = 3(s - 4)

f + 12 = 2(s + 12)

f = 3s - 12

f + 12 = 2s + 24

f = 3s - 12

f = 2s + 12

Since above both equations are in terms of f, set the right sides equal and solve for s.

3s - 12 = 2s + 12

s = 24

f = 3(s - 4)

f = 3(24 - 4)

f = 3(20)

f = 60

Now, the father is 60, and the son is 24.

Which equation is represented by the graph below?

DIA [1.3K]

<h2>Hello!</h2>

The answer is:

The equation that is represented by the shown graph is the equation from the option D.

$y=e^{x}-4$

Since we are given two types of functions, exponential and logarithmic, we need to remember that there is just an option that matches with the graph.

So, from the graph we can see that we are looking for an exponential function which intercepts are located at the point (0,-3) and a point which y-coordinate is equal to 0 and its x-coordinate is located at the x-axis between the number 1 and 2.

From the given options we can see that the only exponential function that intercepts the function at y equal to -3 is the fourth option, so, let's prove that:

Option D,

$y=e^{x}-4$

Finding the y-intercept, we need to make "x" equal to 0, so:

$y=e^{x}-4$

$y=e^{0}-4$

$y=1-4=-3$

So, we know that the y-intercept point is located at (0,-3)

Finding the x-intercept, we need to make "y" equal to 0, so:

$0=e^{x}-4$

$e^{x}=4$

$ln(e^{x})=ln(4)\\x=ln(4)=1.386$

So, we know that the x-intercept point is located at (1.386,0)

Hence, we have that the axis interception points are (0,-3) and (1.386,0), so, the function that matches with the shown graph is the function from the option D.

$y=e^{x}-4$

Have a nice day!

F(x)=x+7 and , g(x)=1/x-13 what is the domain of (f*g) (x) P L E A S E H E L P A S A P !

Kaylis [27]

The inner function g(x) has x-13 in the denominator. Set it equal to 0 and solve for x

x-13 = 0
x-13+13 = 0+13
x = 13

If x = 13 then the denominator of g(x) will be zero. This is a problem since you cannot divide by zero

So x = 13 is not allowed as an input in the g(x) function. The same applies for the composite function as well.

So that's why the domain is the set of all real numbers x but x cannot equal 13

This translates to what choice D is saying, so that is the answer
