What is Exponential Function?

The formula for an exponential function is f (x) = axe, where x is a variable and an is a constant that serves as the function's base and must be bigger than 0. The transcendental number e, or roughly 2.71828, is the most often used exponential function basis.

Given equation

64w¹⁸z¹²

so factors of 64 = 2 x2 x 2 x2 x 2 x2

64 = 2⁶

the equation is 2⁶w¹⁸z¹²

Hence the value of equation is 2⁶w¹⁸z¹².

A closed rectangular tank measures 5 meters by 10 meters by 6 meters. What is the surface area of the tank?

Answers

Answer:

280 square units

Step-by-step explanation:

Using the given dimensions {5, 6, 10}, find the area of the front, top and end of the box: 5*6 + 5*10 + 6*10 = 140 square units.

The back of the box is the same size and shape as the front, the bottom the same as the top, and the other end the same as the first end. Thus, multiply 140 square units by 2 to get the total surface area of the tank:

It is 280 square units.

Jeans are on sale for 25% off. The jeans Bailee wants to buy are marked with an original price of $60. What is the total cost, in dollars, for a pair of jeans at the sale price, including a 7% tax?

Answers

25% of 60 is 15$ so the sale price would be 45$
7% tax = 3.15
= $48.15

I hope this helps :)

The total cost for a pair of jeans at the sale price including 7% tax is $96.30.

What is Percentage?

Percentage, denoted by %, is defined as the parts of a number per fraction of 100.

We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.

here, we have,

Given that,

Original price of the jeans = $60

Discount percentage = 25%

Amount of discount = 25% × 60

= 0.25 × 60

= $15

Price of a jean at the sales price = $60 - $15 = $45

Percentage tax = 7%

Tax amount = 7% × 45 = 0.07 × 45 = $3.15

Price of the jean after tax = $45 + $3.15 = $48.15

Total cost for a pair of jeans = 2 × $48.15 = $96.30

Hence the total cost is $96.30.

2/3(x+6)=-8 whats the value of x?

Answers

Answer:

x=-18

Step-by-step explanation:

Answer:

The answer is -18

Step-by-step explanation:

STEP 1:

[tex]3 \times \frac{2}{3} (x + 6) = 3( - 8)[/tex]

2(x+6) = -24

______________________________________

STEP 2:

Divide both sides by 2:

[tex] \frac{2(x + 6)}{2} = \frac{ - 24}{2} [/tex]

________________________________

STEP 3:

Simplify:

[tex]x + 6 = - 12[/tex]

Subtract 6 from both sides:

[tex]x + 6 - 6 = - 12 - 6[/tex]

________________________________

STEP 4:

[tex]x = - 18[/tex]

Therefore, your answer is -18.
