Answer: The value of x = 4

Step-by-step explanation:

Given : The graph shows a function f(x)=2x

When the value of  f(x)=8, then we have

2x=8

Now, we need to divide 4 on both the sides of the above equation , we get

x=4

Hence, when the value of f(x)=8, then the  value of x = 4

Jim and bill each invest $15,000 into savings accounts that earn 3.5% interest. Jims account earns simple interests and bills ac
Svet_ta [14]

Answer:

Bill will earn more interest

He will earn $ 20,448.67 from his investment

Step-by-step explanation:

Firstly let us calculate Jim's earnings based on simple interest

A = P(1 + rt)

Calculation:

First, converting R percent to r

a decimal

r = R/100 = 3.5%/100 = 0.035 per year.

Solving our equation:

A = 15000(1 + (0.035 × 25)) = 28125

A = $28,125.00

The total amount accrued, principal plus interest, from simple interest on a principal of $15,000.00 at a rate of 3.5% per year for 25 years is $28,125.00 for Jim

Now let's us calculate bill's investment based on compound interest

Equation

A = P(1 + r)^t

A=15000(1+0.035)^25

A=15000(1.035)^25

A=15000*2.36324498427

A = $ 35,448.67

We see that Bill will earn

$ 20,448.67 from his investment

What are the restrictions on the domain (u*v)(x)
Zepler [3.9K]

Answer: x≠0 and x can not be any value for which u(x) = 2

Step-by-step explanation:

According to the question,

The domain of the function u = R - {0}

Thus if x is the element of the domain of the function u

Then , x ≠0

(v*u)(x) = v[u(x)]

Since, The domain of the function v = R - {2}

⇒ u(x) ≠ 2

⇒ Second Option is correct.

A navy submarine descended at a rate of 4 feet per second. a. Write the descent rate as an integer. b. Write an expression to fi
Rasek [7]

Answer:

1200

Step-by-step explanation:

Since the value they are asking for is in minutes, we need to convert seconds to minutes. We can do that by multiplying 4 and 60, because there are 60 seconds in a minute, and we need to find the value of one minute.  Also because the value they gave is 4. When we do this, we get 240. To get the final answer, we need to multiply 240 and 5, because 240 is the descending rate per minute, and they are asking for 5 minutes. When we do this, we get 1200.

(I might get this wrong, so like yeah.)
