Answer:

The copper percentage = 64%

Step-by-step explanation:

Given

Nickle quantity = 9 grams of nickel

Copper quantity = 16 grams of nickel

Total quantity = 25 grams

The percentage of copper metal can be determined using the formula

Copper percentage = [Copper quantity / Total quantity] × 100

= [16 / 25] × 100

= 0.64 × 100

= 64%

Therefore, the copper percentage = 64%

Need help with geometric sequences 30 points

NeTakaya

Answer:

$a_{n}$ = 6 $(5)^{n-1}$

Step-by-step explanation:

The n th term of a geometric sequence is

$a_{n}$ = a $(r)^{n-1}$

where a is the first term and r the common ratio

Here a = 6 and r = 30 ÷ 6 = 5, thus

$a_{n}$ = 6 $(5)^{n-1}$

What is the y-intercept of the function f(x) = -3x Ο Ο on who wire on Ο Ο

morpeh [17]

Answer:

see the explanation

Step-by-step explanation:

we know that

The y-intercept is the value of the function when the value of x is equal to zero. Also is called the initial value of the function

I will analyze two cases

Part 1) we have

$f(x)=-3x$

For x=0

substitute

$f(0)=-3(0)=0$

therefore

The y-intercept is the point (0,0)

Part 2) we have

$f(x)=-3^x$

For x=0

substitute

$f(0)=-3^0=-1$

therefore

The y-intercept is the point (0,-1)
