An equivalent expression without negative exponents of 9^-2 is 1/9²

In this question, we have been given an expression 9^-2

We need to write equivalent expression without negative exponents of 9^-2.

We know that for any number x, the multiplicative inverse of x is represented as x^-1 which is equal to 1/x

We can write 9^-2 as,

9^-2

= 9^(2 × -1)

= (9²)^-1

= 1/9²

Therefore, an equivalent expression without negative exponents of 9^-2 is 1/9²

Using proportions, it is found that the height of the object is of 12 m, hence you can use a ladder that reaches height of up to 13 m to climb the object.

A proportion is a fraction of a total amount, and the measures can be related using a rule of three, which derives from proportional relationships.

Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures, involving operations such as division and multiplication, as they involve unit rates.

For similar triangles, equivalent side lengths are proportional, hence, in this problem, we have that:

h/1.5 = 8.8/1.1

h/1.5 = 8

h = 8 x 1.5

h = 12m.

The height of the object is of 12 m, hence you can use a ladder that reaches height of up to 13 m to climb the object.

Answer:

13 gallons

If the car is able to travel 30 miles per gallon and has a 16-gallon fuel tank, its total fuel efficiency is found by evaluating the product of the two factors.

Therefore, we can multiply 30 by 16 and find the total mileage that the car is equipped to travel:

[tex]30\times16=480[/tex]

Now, assuming that the car has a full tank of gas, it travels 90 miles on the highway. We can find out the remaining fuel efficiency by subtracting 90 miles from the maximum fuel efficiency:

[tex]480-90=390[/tex]

Then, since the car can travel 30 miles per gallon, divide this fuel efficiency by 30 miles to find the remaining gallons in the tank:

[tex]\displaystyle \frac{390}{30} = 13[/tex]

[tex]\boxed{\bold{13 \ gallons}}[/tex]

here's your answer check if it's right or not

Answer:

p = 6

Step-by-step explanation:

Define the variable

Let p be the number of people who go to the amusement park.

Given information:

Therefore, the equation that represents the given information and the defined variable is:

[tex]39.25p + 12 \leq 247.50[/tex]

(We have used the inequality sign since the question states the maximum amount of money the group of friends have to spend).

To solve, subtract 12 from both sides:

[tex]\implies 39.25p + 12 - 12 \leq 247.50 - 12[/tex]

[tex]\implies 39.25p \leq 235.50[/tex]

Divide both sides by 39.25:

[tex]\implies \dfrac{39.25p}{39.25} \leq \dfrac{235.50}{39.25}[/tex]

[tex]\implies p\leq 6[/tex]

Therefore, the maximum number of people that can go to the amusement park is 6.

Function (D) f(x) = |x| is even.

To find which functions are even:

We are aware that a function is even when f(x) = f(-x).

(A)

[tex]$$\begin{aligned}&\text f(x)=x^{4-x^2} \\&f(-x)=(-x)^{4-x^2} \\&f(x) \neq f(-x)\end{aligned}$$[/tex]

So, the function is not even.

(B)

[tex]$$\begin{aligned}& f(x)=x^2-3 x+2 \\&f(-x)=x^2+3 x+2 \\&f(x) \neq f(-x)\end{aligned}$$[/tex]

So, the function is not even.

(C)

[tex]$$\begin{aligned}&\text f(x)=\sqrt{x-2} \\&f(-x)=\sqrt{-x-2} \\&f(x) \neq f(-x)\end{aligned}$$[/tex]

So, the function is not even.

(D)

[tex]f(x)=|x|\\f(-x)=|-x|=|x|=f(x)[/tex]

So, the function is even.

A mother will need 2 jars of meat and 1 jar of vegetable for 5g of protein and 3 jars of meat and 1 jar of vegetable for approx 120 calories.

Given that, a mother is choosing which baby foods to serve her infant. A jar of meat has 2g of protein and 34 calories. A jar of vegetables has 1g of protein and 17 calories. Now , we have to calculate how much she will be needed if she wants to serve 5g of protein and 120 ​calories respectively.

So, let's proceed to solve this question.

For 5g of protein she will be needed 2 jars of meat having 2g protein and 1 jar of vegetables which has 1g protein, then total protein will be equals to 5g.

5g of protein = 2 x A jar of meat + 1 x A jar of vegetables

For 120 calories, she will be needed 3 jars of meat and 1 jar of vegetable then it comes out to be 119 calories approximately equals to 120 calories.

So, 2 jars of meat and 1 jar of vegetable for 5g of protein and 3 jars of meat and 1 jar of vegetable for approx 120 calories.

Therefore, 2 jars of meat and 1 jar of vegetable for 5g of protein and 3 jars of meat and 1 jar of vegetable for approx 120 calories is the required answer.

The total charge for the rooms will be $197.55.

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 unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given,

The charge for one room = $21.95

Total number of rooms = 3+2+4=9 rooms

Total charges for the room= Charge for one room × total number of room

Substitute the values:-

The total charge for the room = 21.95 × 9 = 197.55

The value of the given number is -10.

Here, we are given that Thirty-five more than 0.8 times a number is the same as 43 less than the product of -7 and the number.

Let the number be x

0.8 times x = 0.8

35 more than 0.8x = 35 + 0.8x

Thus, our left hand side of the equation is 35 + 0.8x

Now, the product of -7 and x = -7x

43 less than -7x = -7x - 43

Thus, we get the following equation-

35 + 0.8x = -7x - 43

we can solve this equation to find the value of x-

0.8x + 7x = -43 - 35

7.8x = -78

x = -78/ 7.8

x = -1/ 0.1

x = -10

Thus, the value of the given number is -10.
