Answer:

The width of the room would be 40 meters

Step-by-step explanation:

To find this, start with the area formula.

A = LW

Now input the known length and area.

2400 = 60W

Now divide both sides by 60

40 = W

Joe barrowed $2,000 from the bank at a rate of 7% simple interest per year. How much will be in your account in 5 years?
timofeeve [1]
For the answer to the question above,
The simple interest formula is I = P * r * t

P is the principal (2,000)
r is the interest rate (7% or 0.07)
t is the time (5)

2000 * 0.07 * 5 = 700

$700.00 is the interest

Joe has to pay $700.00 in interest.

Our x is equal to =x= \frac{486*15}{135} =54min
Its our result

Consider the function f ( x ) = 1 − 4 x 2 on the interval [ − 1 , 3 ] . Find the average or mean slope of the function on this i
Blababa [14]

Answer:

The average slope is 8.

Step-by-step explanation:

Let <em>f</em> be defined on the closed interval [a, b]. The average slope of <em>f </em>between a and b is the quotient

                                       average slope = \frac{f(b)-f(a)}{b-a}

To find the average slope of the function f(x)=1-4x^2 on the interval [-1, 3] you have to evaluate your function in the interval and then divide by the interval.

So,

f(-1)=1-4(-1)^2=-3\\\\f(3)=1-4(3)^2=-35

The average slope is  \frac{f(3)-f(-1)}{3+1}= \frac{-3+35}{3+1}=\frac{32}{4}=8
