What is the initial value in the equation f(x) = 350(1 - 0.12)^x? *
kvasek [131]

Given:

The function is:

f(x)=350(1-0.12)^x

To find:

The initial value of the function.

Solution:

We have,

f(x)=350(1-0.12)^x

The value of the function at x=0 is called the initial value of the function.

For x=0, we get

f(0)=350(1-0.12)^0

f(0)=350(0.88)^0

Clearly 0.88 is a non zero number and zero to the power of a non zero number is always 1.

f(0)=350(1)

f(0)=350

Therefore, the initial value of the function is 350.

You and your friend each collect rocks and fossils. Your friend collects three times as many rocks and half as many fossils as y
tino4ka555 [31]

Answer:

Number of rocks and fossils collected by you is 1 and  24 respectively

Number of rocks and fossils collected by your friend is 3 and 12 respectively

Step-by-step explanation:

Let  the number of Rocks you collect be x

Let  the number of Fossils you collect be y

Then the total number pf objects you collected will be

x + y = 25

x = 25 - y------------------------------(1)

Your friend collects three times as many rocks and half as many fossils as you.

This can be written as

3x + y(\frac{1}{2}) = 15

3x + (\frac{y}{2}) = 15-------------------(2)

Substituting (1) in (2)

3(25 -y) + (\frac{y}{2}) = 15

75 - 3y + (\frac{y}{2}) = 15

Grouping the like terms we get,

75 - 15 = 3y - (\frac{y}{2})

60= \frac{6y-y}{2})

60 \times 2= 6y-y

120= 5y

y = \frac{120}{5}

y= 24

Substituting  y value in equation(1) we get

x = 25 - 24

x= 1

Friends collects 3 times rock

so collects 3x =3(1) = 3rocks

Also he collects half as many fossils

That is

\frac{y}{2} = \frac{24}{2} =12 fossils

A) Necsito Ayudaa Con Eso<br />ayuden Porfa<br /-3x-7y=8 3x-2y=-44
STALIN [3.7K]
Hi! 

[1] -3x-7y=8
[2] 3x-2y=-44

lets take [1]
-3x-7y=8
-7y=8+3x
-7y-8=3x
3x=-7y-8

No use 3x=-7y-8 and put it in 3x-2y=-44
-7y-8-2y=-44
-9y-8=-44
-9y=-36
9y=36
y=4

then use y in 3x-2y=-44
3x-2(4)=-44
3x-8=-44
3x=-36
x=-12
Therefore, y = 4 and x = -12
