Answer:

Step-by-step explanation:

Given the expression [tex](4z^8)^{-3}[/tex], to evaluate this, we will use one of the law of indices as shown;

[tex](a^m)^n = a^{mn}[/tex]

[tex]4^{-3} * z^{8*-3}[/tex]

[tex]= \frac{1}{4^3} * z^{-24}\\ \\= \frac{1}{64} * \frac{1}{z^{24}}\\ \\= \frac{1}{64z^{24}}[/tex]

Mario's error was that she did not raise the value of 4 to the power of -3. She only raised z^8 to the power of -3 when it is supposed to affect both 4 and z^8

Answer:

The value of x = 12

Step-by-step explanation:

Here, we are to find the value of x

If the two angles are supplementary, it means that they add up to be 90 degrees

Thus;

∠GHJ + ∠MHJ = 90

6x + 18 = 90

6x = 90-18

6x = 72

x = 72/6

x = 12

Answer: b & d

Step-by-step explanation:

These are complex roots because they do not have x-intercepts.

Answer:

9⁻⁶

Step-by-step explanation:

When you're dividing, you subtract the exponents. So, 3-9=-6.

The expression 9³ / 9⁹ can be written as 9⁻⁶.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

The given expression is 9³ / 9⁹. The expression can be solved as below:-

E = 9³ / 9⁹

E =  9³ x 9⁻⁹

E = 9³⁻⁹

E = 9⁻⁶

Therefore, the expression 9³ / 9⁹ can be written as 9⁻⁶.

[tex]y=-2+6x[/tex]

Answer:

Step-by-step explanation:

given data

let the total charge be y

and let the number of pound be n

also let the charge per pound be p

we know that the expression for the total charges is given as

y=2+np

given that

y=$38

n=9

the expression the charges is now

38=2+9p

solving for p we have

38-2=9p

36=9p

p=36/9

p=4

therefore she is charged $4 per pound

Answer:

V₂ = 450 cm³

Step-by-step explanation:

The volume of a gas V held at a constant temperature in a closed container varies inversely with its pressure P.

[tex]V\propto \dfrac{1}{P}[/tex]

If V₁ = 600 cm³, P₁ = 300 mm hg, P₂ = 400 mm hg

We need to find a new volume. Using the above concept,

[tex]V_1P_1=V_2P_2\\\\V_2=\dfrac{V_1P_1}{P_2}\\\\V_2=\dfrac{600\times 300}{400}\\\\V_2=450\ cm^3[/tex]

So, when the pressure is 400 mm hg, its volume is 450 cubic centimeters

Ommited Answer Choices:

A. 4 inches, 4 inches, 4 inches

B. 3 inches, 3 inches, 3 inches

C. 3 inches, 3 inches, 2 inches

D. 2 inches, 2 inches, 3 inches

Answer:

C. 3 inches, 3 inches, 2 inches

Step-by-step explanation:

The ratio of the corresponding lengths of two similar polygons will always be equal.

Thus, the ratio of the smaller sides of both similar isosceles ∆ should equal the ratio of the other sides.

Thus, from the options given, the side measurements that could be that of the smaller triangle are: 3 inches, 3 inches, 2 inches.

This is because: ratio of one of the equal side of the larger triangle to one of the equal side of the smaller triangle equal ratio of the shortest side of the bigger triangle to the shortest side of the smaller triangle.

Thus: 6/3 = 4/2 = 2.

Answer:

The change is increased by 80%.

Step-by-step explanation:

Divide 36 by 45. This gives you 0.8. Divide 36 by 0.8 and multiply 45 by 0.8 to check your answer. So, it is increased by 80%. To find out how percents change, divide the first number by the second number. Then, take the decimal and move the decimal point over to the right two spaces, or multiply the entire number by 100.

Answer:

k = p(K+t)

Step-by-step explanation:

p = k/K+t // × (K+t)

p(K+t) = k

Answer:

k = K p - K t

Step-by-step explanation:

Solve for k:

p = k/K + t

p = k/K + t is equivalent to k/K + t = p:

k/K + t = p

Subtract t from both sides:

k/K = -t + p

Multiply both sides by K:

Answer: k = K p - K t

Answer:

Neither Dom or Riley is correct

Step-by-step explanation:

The change in temperature between 12PM and 6AM can be obtained by subtracting the 12PM temperature from the 6AM temperature because temperature increases as the hours of the day go by.

To carry out this subtraction on the number line, the following steps should be taken;

(i) Mark the numbers corresponding to 6AM and 12PM temperatures on same number line.

(ii) From the number corresponding to the 12 PM temperature, find out how many steps that are needed to reach the position of the number corresponding to the 6AM temperature.

This number of steps represents the temperature change between the 12PM temperature and the 6 AM temperature.
