[tex] \large1) \sf {2}^{8x} = {2}^{5 x+ 15} [/tex]

[tex] \large \: 2)\sf {2}^{ - 4x} = {2}^{2x + 2} [/tex]

Step-by-step explanation:

to understand thisyou need to know about:law of exponentPEMDASlet's solve:[tex] \sf rewrite \: 16 \: as \: {2}^{4} : \\ \sf {2}^{4(2x)} = {32}^{x + 3} [/tex][tex] \sf rewrite \: 32 \: as \: {2}^{5} : \\ {2}^{4(2x)} = {2}^{5(x + 3)} [/tex][tex] \sf distribute : \\ \sf {2}^{8x} = {2}^{5 x+ 15} [/tex]

let's figure out the second one:

[tex] \sf rewrite \: \frac{1}{16} \: as \: {2}^{ - 4} : \\ \sf {2}^{ - 4(x)} = {4}^{x + 1} [/tex][tex] \sf rewrite \: 4 \: as \: {2}^{2} : \\ \sf {2}^{ - 4(x)} = {2}^{2(x + 1)} [/tex][tex] \sf distribute : \\ {2}^{ - 4x} = {2}^{2x + 2} [/tex]

Courtney is ordering nachos at a restaurant, and the server tells her that she can have up to three toppings: pico de gallo, onions, and steak. Since she cannot decide how many of the toppings she wants, she tells the server to surprise her. If the server randomly chooses which toppings to add, what is the probability that Courtney gets just onions and steak

Answers

Answer:

[tex]Probability = \frac{1}{9}[/tex]

Step-by-step explanation:

Given

Toppings: Pico de gallo, Onions and Steak

Required

The probability of getting Onions and Steak

The probability is calculated using:

[tex]Probability = P(Onion)\ and\ P(Steak)[/tex] --- because the events are independent

[tex]P(Onion) = \frac{n(Onion)}{Total}[/tex]

[tex]P(Onion) = \frac{1}{3}[/tex]

[tex]P(Steak) = \frac{n(Steak)}{Total}[/tex]

[tex]P(Steak) = \frac{1}{3}[/tex]

So, we have:

[tex]Probability = P(Onion)\ and\ P(Steak)[/tex]

[tex]Probability = P(Onion)\ *\ P(Steak)[/tex]

[tex]Probability = \frac{1}{3} * \frac{1}{3}[/tex]

[tex]Probability = \frac{1}{9}[/tex]

Answers

Answer:

11.56

Step-by-step explanation:

The area formula is just Length * Height. Since this shape is a square, both the length and height are equivalent to the same thing, 3.4. So, all we have to do is multiply 3.4 * 3.4, or we can do 3.4^2.

A positive integer is 4 less than another. If 3 times the reciprocal of the smaller integer is subtracted from the reciprocal of the larger integer, then the result is −67. Find all pairs of integers that satisfy this condition.

Answers

Answer:

(0.0147, 4.0147) and (-4.04, 0.04)

Step-by-step explanation:

Let the smaller number be x

Let the larger number be y

If a positive integer is 4 less than another, then;

x = y - 4 ...1

If 3 times the reciprocal of the smaller integer is subtracted from the reciprocal of the larger integer and result is -67, then;

1/y - 3(1/x) = -67

1/y   -3/x = -67 ...2

Substitute 1 into 2

1/y - 3/y-4 = -67

y-4-3y/y(y-4) = -67

-4-2y = -67(y^2-4y)

- 4-2y = -67y^2 +268y

-67y^2 +268y+2y + 4  = 0

-67y^2 +270y +  4 =0

67y^2 -270y - 4 = 0

Factorize

-270±√270² - 4(-4)(67)/2(67)

= -270±√72,900+1072/134

= -270±271.97/134

= -270 -271.97/134 and  -270 +271.97/134

= -541.97/134 and 1.97/134

x = 0.0147 and -4.04

y = x+4

y = 0.0147+4

y = 4.0147

If x = -4.04

y = -4.04 + 4

y = 0.04

Hence the pair of values are (0.0147, 4.0147) and (-4.04, 0.04)

Howard buys 5 suits a year when he earns $70,000. When his income increases to $200,000, he buys 15 suits a year. Based on this
information, suits are considered to be
a complementary good.
an inferior good.
a neutral good.
a normal good.
a substitute good.

Answers

Answer:

a complementary good

Step-by-step explanation:

Howard spends $70,000 per year on 5 suits. When his income reaches $200,000, he purchases 15 suits per year. Suits are classified as a normal good based on this information.

What is meant by Normal Good?A normal good is one that sees an increase in demand due to an increase in consumer income. In other words, an increase in wages leads to an increase in demand for ordinary goods, whereas a decrease in wages or layoffs leads to a decrease in demand. In economics, an inferior good is one whose demand falls when consumer income rises (or rises when consumer income falls), as opposed to normal goods, which experience the opposite effect. Normal goods are those whose demand increases as consumer income rises. Normal goods are those for which the relationship between consumer income and quantity demanded is positive. In other words, the income effect is positive while the substitution effect is negative.

Ronald is calculating the density of oranges in a crate. He knows the number of oranges in the crate and the volume of the crate. Which of the following formulas can be used to calculate the density of oranges in the crate? (6 points) Density = volume of crate over number of oranges Density = number of oranges over volume of crate Volume of shelf = density over number of oranges Number of books = density over volume of crate

Answers

Answer:

B. Density = number of oranges over volume of crate

Step-by-step explanation:

The density would be the number of oranges per unit of volume:

Density = number of oranges / volume of crate

Correct choice is B

Density = number of oranges over volume of crate Volume of shelf is right formula
