F(x)=x^2-6x g(x)= √x Evaluate f(g(25)) = ???

damaskus [11]

Answer:

f(g(25)) = -5

Step-by-step explanation:

You have to put 25 in place of x in g, and after, you take the result and put in place of x in f:

g(5) = √25 = 5

f(5) = 5^2 -6•5

f(5) = 25 -30

f(5) = -5

X + 2y = 10 y=x-4 Choices are: (0,4) (2,6) (6,2) (8,0) Work shown

LuckyWell [14K]

Answer:

C) (6,2)

Step-by-step explanation:

Rewrite equations:

y=x−4;x+2y=10

Step: Solve y=x−4for y:

y=x−4

Step: Substitute x − 4 for y in x+2y=10:

x+2y=10

x+2(x−4)=10

3x−8=10(Simplify both sides of the equation)

3x−8+8=10+8(Add 8 to both sides)

3x=18

(Divide both sides by 3)

x=6

Step: Substitute6forxiny=x−4:

y=x−4

y=6−4

y=2(Simplify both sides of the equation)

Hope this helps!

Samuel bought a cement mixer for $54,205. The value of the cement mixer depreciated at a constant rate per year. The table shows

Paul [167]

The value of cement mixer after t year is $f(t) = 54,205(0. 87)^{t}$

Given to us

The value of cement mixer when bought, $P$ = $ 54,205

the value of cement mixer after 1 year, $P_1$ = $ 47,158. 35

the value of cement mixer after 2 year, $P_2$ = $ 41,027. 76

To find out depreciation we can use the formula for depreciation,

$P_n= P(1-r)^n\\where,\\P_n= Value\ of\ asset\ after\ n\ year\\P= Value\ of\ asset\ when\ bought\\r= rate\ of\ depreciation\\n= number\ of\ years$

By putting the value, in the formula we get,

$P_1= P(1-r)^n\\\\47,158.35= 54,205\times (1-r)^1\\\\\dfrac{47,158.35}{54,205} = (1-r)\\\\0.87=1-r\\\\r=0.13$

Therefore, putting the value of $r$ and $P$ in depreciation formula for $t$ years we get,

$P_n= P(1-r)^n$

$f(t) = 54,205(0. 87)^{t}$

Hence, the value of cement mixer after t year is $f(t) = 54,205(0. 87)^{t}$ .
