Short side length = x

Medium side = x + 7

Long side = 5x

Total 49, so

x + x + 7 + 5x = 49

If you combine like terms:

7x + 7 = 49

Subtract 7 from both sides

7x = 42

Divide both sides by 7

x = 6 inches.

Identify which of the six parent functions are even, which are odd, and which are neither. You may graph the functions or refer

guapka [62]

Even- quadratic, constant, rational (inverse squared), absolute value
odd- linear, cubic, rational (inverse), cube root
neither- greatest integer, exponential, log, radical (square root)

i hope this helps sorry i couldn’t remember all of them

Find the area:......Brainliest........

pav-90 [236]

Answer:

Step-by-step explanation:

The average length of the weird trapezoidal shape on the left is

(2 m + 10 m)/2, or 6 m. The width is 4 m, so the area is 24 m^2.

The area of the semicircle is (1/2)(pi)(2 m)^2, or 2pi m^2.

Thus, the overall area of the green shape is 24 m^2 + 2pi m^2.

A solid object is dropped into a pond with a temperature of 20 degrees Celsius. The function f(t)=Ce(−kt)+20 represents the situ

LenaWriter [7]

Answer:

The initial temperature of the object was 37.6 degrees Celsius

The initial temperature of the object was 37.6 (without units)

Step-by-step explanation:

we have

$f(t)=Ce^{(-kt)} +20$

where

f(t) represent the temperature of the object in degree Celsius

t is the time in minutes

<em>Find the value of the constant C</em>

we have the ordered pair (4,35)

substitute in the equation and solve for C

$35=Ce^{(-0.0399*4)} +20$

$Ce^{(-0.0399*4)}=15$

$C=15/e^{(-0.0399*4)}$

$C=17.6$

Find the initial value of the object

we know that

The initial temperature is the value of f(t) when the value of t is equal to zero

For t=0

$f(0)=(17.6)e^{(-k*0)} +20$

$f(0)=17.6 +20$

$f(0)=37.6\ degrees\ Celsius$

therefore

The initial temperature of the object was 37.6 degrees Celsius

The initial temperature of the object was 37.6 (without units)
