Answer:

(-6, 0) and (3, 0)

Step-by-step explanation:

I think you meant f(x) = (x + 6)(x - 3). This graph intersects the x-axis in two places: (-6, 0) and (3, 0). These are the "x-intercepts."

At Simba Travel Agency, the price of a climbing trip to Mount Kilimanjaro includes an initial fee plus a constant fee per meter.

Alexus [3.1K]

Answer: $110

Step-by-step explanation:

Given: At Simba Travel Agency, the price of a climbing trip to Mount Kilimanjaro includes an initial fee plus a constant fee per meter.

F(d)models the fee (in dollars) for climbing d meters.

$F(d)=110+0.12d$

To find the initial amount, substitute d=0 int the above function, we get

$F(0)=110+0.12(0)=110$

Hence, the initial fee= $110.

A half-acre building lot is five times as long as it is wide. What are its dimensions?

Gnoma [55]

we know that

A half-acre is equal to----------> $2,023.43\ m^{2}$

Let

x---------> the length side of the building lot

y--------> the width side of the building lot

A------> Area of the building lot

x=5y-------> equation 1

$A=2,023.43\ m^{2}$

$A=x*y$

$2,023.43=x*y$ --------> equation 2

substitute equation 1 in equation 2

$2,023.43=[5y]*y$

$5y^{2}= 2,023.43\\y^{2}= 404.686\\y= 20.11\ m$

Find the value of x

$x=5y---> x=5*20.11--> x=100.55 m$

therefore

the answer is

the dimensions of the building lot are 100.55 m* 20.11 m
