What is logarithm?

When you raise a number with an exponent, there comes a result.

Let's say you get

a^b = c

Then, you can write 'b' in terms of 'a' and 'c' using a logarithm as follows

[tex]b = \log_a(c)[/tex]

'a' is called base of this log function. We say that 'b' is the logarithm of 'c' to base 'a'

Erika is working on solving the exponential equation 50^x = 17;

however, she is not quite sure where to start.

The equation is

[tex]50^x = 17\\[/tex]

By taking the log both sides

[tex]log_a b = x\\\\a_x = b[/tex]

By using the base formula

If you pull a card from a standard deck of 52 and then pull a second card without replacing the first card, you have about a ____ chance(round to nearest percent) of pulling out a face card, followed by on ace.

Answers

The probability that you pull a card from a standard deck of 52 and then pull a second card without replacing the first card is 2%

How to determine the probability?

The given parameters are:

Cards = 52

Face card = 12

Ace = 4

The probability of selecting a face card is:

P(Face card) = 12/52

Now, there are 51 cards.

The probability of selecting an ace is:

P(Ace) = 4/51

The required probability is:

P = 12/52 * 4/51

Evaluate

P = 0.0181

Express as percentage

P = 1.81%

Approximate

P = 2%

Hence, the probability is 2%

Ingrid Nilsen purchased a $4,000 hydroponic system for her garden. The down payment is 20%, and the
installment loan has an APR of 10% for 36 months. Find the a) down payment, b) amount financed, c) monthly
payment, d) total amount repaid, and e) finance charge.

Answers

The purchase of the hydroponic system by Ingrid Nilsen for $4,000 with a 20% down payment at 10% APR for 36 months, and the related calculations, are as follows:

a) down payment = $800.00 ($4,000 x 20%)

b) amount financed = $3,200 ($4,000 - $800)

c) monthly payment = $103.25

d) total amount repaid = $4,517

e) finance charge = $517

How is periodic payment computed?

The amount of the periodic payment, finance charge, and total repayment can be computed using an online finance calculator as follows:

Data and Calculations:

Auto Price = $4,000

Loan Term = 36 months

Interest Rate = 10%

Down Payment = $800 ($4,000 x 20%)

Monthly Payment = $103.25

Total Loan Amount $3,200.00

Upfront Payment = $800.00 ($4,000 x 20%)

Total of 36 Loan Payments = $3,717. ($103.25 x 36)

Total Loan Interest = $517

Total Cost (price, interest, tax, fees) = $4,517

Thus, Ingrid Nilsen repaid a total of $4,517 with $517 in interest (finance charge).

What is the slope of the line represented by the equation y + 3 = -4(x-5)?
OA. 3

O C. -3
OD. -4

Answers

Answer:

-4

Step-by-step explanation:

if you graph it, we can find out two points are 0,17 and 1,13

we can find the slope from rise/run

-4 is the slope of the line represented by the equation y + 3 = -4(x-5)

What is Slope of Line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The equation of the line is y + 3 = -4(x-5)

We have to find slope

Let us simplify the equation to slope intercept form to find slope

y+3=-4x+20

y=-4x+17

Hence, -4 is the slope of the line represented by the equation y + 3 = -4(x-5)

pleeeeeeeeeeeeeeeeas FAST !!!!! i need help if a/b = (-7/9)^8 / (-7/9)^6 find the value of (a/b)^2.

Answers

Answer:

(-7/9)^4 = 2401/6561

Step-by-step explanation:

The rules of exponents apply.

(a^b)/(a^c) = a^(b-c) . . . . . quotient rule

(a^b)^c = a^(bc) . . . . . . . . power rule

value of a/b

The first rule of exponents shown above helps us find the value of a/b.

[tex]\dfrac{a}{b}=\dfrac{\left(\dfrac{-7}{9}\right)^8}{\left(\dfrac{-7}{9}\right)^6}=\left(\dfrac{-7}{9}\right)^{8-6}=\left(\dfrac{-7}{9}\right)^2[/tex]

The second rule of exponents shown above tells us how to find the square.

[tex]\left(\dfrac{a}{b}\right)^2=\left(\left(\dfrac{-7}{9}\right)^2\right)^2=\left(\dfrac{-7}{9}\right)^{2\times2}\\\\\boxed{\left(\dfrac{a}{b}\right)^2=\left(\dfrac{-7}{9}\right)^4=\dfrac{2401}{6561}}[/tex]

a) 266.39
b) 294.76
c) 525.51
d) 304

Answers

Answer:

A) 266.39

Step-by-step explanation:

Answer:

a) 266.39 unit^2.

Step-by-step explanation:

Area of the base = 8^2 = 64 .

There are 4 triangular sides.

To find the area of 1 side we need to know the slant height s of the triangle, This can be found using the Pythagoras Theorem

s^2 = 4^2 + 12^2 = 160

s = √160

So the area of 1 side = 1/2 * base * s

= 1/2 * 8 * √160

and

area of 4 sides

= 4 * 1/2 * 8 * √160

= 202.386

So the Surface area of the pyramid

= 64 + 202.386

= 266.386
