Given f(x)=2x²+4, find the value of f(−1)

log(x) - log (3) = 8 => x = 299916251.899, by properties of logarithm.

Now,

log (x) - log (3) = 8

=> log (x) = 8 + log (3) = 8 + 0.477

=> log (x) = 8.477

Since, generally the base of log is 10, raising them to 10.

=> [tex]10^{log_{10}x} = 10^{8.477}[/tex]

=> x = 299916251.899 (as  [tex]a^{log_a(x)} = x[/tex])

Hence, log(x) - log (3) = 8 => x = 299916251.899, by properties of logarithm.

Answer: 7 units right and 1 unit down/ J(-3, 1), F(-2, 3), N(-2, 0)

                              J(-3, 1) = J'(4, 0)

                              F(-2, 3) = F'(5, 2)

                              N(-2, 0) = N'(5, -1)

Step-by-step explanation:

If you want to translate a point 7 units right, you'll need to add 7 to its x-coordinate. If you want to translate a point 1 unit down, you'll need to subtract 1 from its y-coordinate. Do both of these things to perform a translation 7 units right and 1 unit down.

So, we can write,

            7 units right means add the +7

             1 unit down means subtract the -1

Then,

                  J(-3, 1) = J'(-3 + 7, 1 - 1)

                  J(-3, 1) = J'(4, 0)

                  F(-2, 3) = F'(-2 + 7, 3 - 1)

                  F(-2, 3) = F'(5, 2)

                  N(-2, 0) = N'(-2 + 7, 0 - 1)

                  N(-2, 0) = N'(5, -1)

Therefore,

These points to make sure they have shifted 7 units right and 1 unit down.

   7 units right and 1 unit down/ J(-3, 1), F(-2, 3), N(-2, 0)

                              J(-3, 1) = J'(4, 0)

                              F(-2, 3) = F'(5, 2)

                              N(-2, 0) = N'(5, -1)

Answer:

50 meters

Step-by-step explanation:

Width is x

So length will be x + 20

Perimeter = 2 (W + L) = 2 (x + x + 20) = 2 (2x + 20) = 4x + 40

so 4x + 40 = 160

4x = 120

x = 30

so length = x + 20 = 30 + 20 = 50

The values of three consecutive even integers must be if their sum is 6000 will be 1998, 2000, and 2002.

it is defined as a whole number it can be a negative whole number or a positive whole number for example 2, 4, 1, -8, 0, etc. When it comes to integers, even numbers can be divided by two exactly while odd numbers cannot. 2, 6, 10, 20, 50, and other even numbers serve as examples.

Suppose the value of the three consecutive even integers is n, n + 2, and n + 4

The sum of the integers is 6000.

Sum = n + n + 2 + n + 4

Sum = 3n + 6

Sum=6000

3n + 6 = 6000

3n =  5994

n = 5994/3

n = 1998

The three consecutive even integers are,

n=1998

n+2=1998+2=2000

n+4=1998+4=2002

Thus, the values of three consecutive even integers must be if their sum is 6000 will be 1998, 2000, and 2002.

The account balance invested at 6. 5% annual interest compounded annually will take 19.1 years to reach $50,000.

Compound interest refers to the amount of interest added on the principal amount plus interest. The formula for compound interest is:

B = P(1 + r/n)^t

where B is the ending balance, P is the principal amount or original balance, r is the interest rate in decimal form, n = number of times interest is compounded annually, and t is the time in number of year

Using this formula, find t, the time it will take the account to reach $50,000 when

B = $15,000

r = 6.5% = 0.065

n = 1

B = P(1 + r/n)^t

$50,000 = $15,000(1 + 0.065/1)^t

(1 + 0.065)^t = $50,000/$15,000

Option C: Samantha is correct because when using x=2, the resulting values in both expressions are equal.

Consider, 4x + 2

When x = 2,

=> 4x + 2 = 4*2 + 2

=> 10

Now consider, x + 17 + 3x - 15

When x = 2,

=> 2 + 17 + 3*2 - 15

=> 10

Therefore, Samantha is correct as both expressions equal 10 when x=2.

In other words, if we consider, x + 17 + 3x - 15

=> x + 17 + 3x - 15

=> x(1+3) + 17 - 15

=> 4x + 2

This shows that for any value of x, the expression x + 17 + 3x - 15, simplifies to 4x + 2.

Therefore, both the expressions, 4x + 2 and x + 17 + 3x - 15, are equal.

The option B , that is , an antique vase valued at $125,000 can be categorized as collateral asset.

What is a collateral asset ?

An asset that a borrower pledges to a lender as a guarantee that the loan will be repaid is known as collateral asset.

We know that the assets that a lender accepts as security for a loan are referred to as collateral. That meant lenders are protected by the collateral in this way. To put it another way, if the borrower stops making loan payments, the lender may be able to sell the collateral to collect some or all of its losses.

So , let's check which of the given option falls under category of collateral.

A.

This is not collateral asset because for a credit card there is no security money given to bank. We only need to pay a maintenance charge and nothing else.

B.

This is a collateral asset.

For an antique vase whose value is $125000 , if the person has purchased this by taking a loan then he would have paid some security money as deposits. If any case he is not able to pay the loan by time the property or the asset becomes collateral which meant the lender may sell the asset to some or all of his losses.

C.

This is not collateral asset because if the loan is repaid in full there will be no extra charges liable on the asset and it can't be categorized as collateral.
