Answer:

108 ft

Step-by-step explanation:

The total length in inches of the perimeter of the model is ...

7 in + 3 in + 3 in + 5 in = 18 in

The total length of the walkway will have the same ratio to this perimeter that the corresponding sides have:

EF/AB = 42 ft/(7 in) = (walkway length)/(18 in)

Multiplying by 18 in, we get ...

walkway length = (42 ft)(18 in)/(7 in)

walkway length = 108 ft

A farmer is tilling a rectangular field that is 65 meters long and 72 meters wide. What is the distance between opposite corners

ss7ja [257]

Answer:

97m

Step-by-step explanation:

From the image below we solve using pythagoras's theorem

x^2 = 72^2 + 65^2

x^2 = 5184 + 4225

x^2 = 9408

x = 97 m.

Further explanation is shown 8n the image.

The growth factor of the exponential function represented by the table is 5.

The correct option is c.

<h3>What is the growth factor of the exponential function?</h3>

The growth factor of the exponential function is the ratio of the two consecutive terms (y-values).

The growth factor of the exponential function is given by;

$\rm Growth\ factor=\dfrac{y(x_2)}{y(x_1)}\\\\$

As per given, we have a table;

x y

-2 0.004

-1 0.02

0 0.1

1 0.5

The value $\rm x_2$ is -2 and $\rm x_1$ is -1.

Therefore,

the growth factor of the exponential function represented by the table would be :

$\rm Growth\ factor=\dfrac{y(x_2)}{y(x_1)}\\\ \rm Growth\ factor=\dfrac{y(-1)}{y(-2)}\\\\\rm Growth\ factor=\dfrac{0.02}{0.004}\\\\ \rm Growth\ factor=5$

Hence, the growth factor of the exponential function represented by the table is 5.

You are saving money to buy a used car. You deposit $2,500 in an account that earns interest compounded annually. The expression

seraphim [82]

Answer:

$r= [(\frac{A}{2500}) ^\frac{1}{2} -1]$

Step-by-step explanation:

Given data

Principal = $2500

time t= 2 years

Required

the rate r

Given the expression for the balance 2500(1+r)^2

Hence

$A= 2500(1+r)^2$

we can make r subject of formula

$r= [(\frac{A}{P}) ^\frac{1}{t} -1]$

$r= [(\frac{A}{2500}) ^\frac{1}{2} -1]$

Hence, for any value of A, we can find the rate using the expression above
