Answer:

c=a2+b2

Step-by-step explanation:

Find the value of x.

The side opposite the right angle is the side labelled x. ...

x=√100=10.

Maybe you remember that in an equation like this, x could also be –10, since –10 squared is also 100. ...

Find the value of y.

y=√80=√16×5=4√5.

x=√17.45≈4.18 miles.

Answer:

thats the formula

a^2 + b^2 = c^2

Step-by-step explanation:

a =  side of the right angle/adjacent side

b = side of the right triangle/opposite side

c= hypotenuse

Change from rectangular to spherical coordinates: In spherical coordinates, (0, 3, -3) is (3, π/2, 5π/4) and In spherical coordinates, (-6, 6, 6√2) is (√108, π/4, π/2).

In spherical coordinates, a point in three-dimensional space is represented by three coordinates: ρ (rho), θ (theta), and φ (phi).

For part (a), we can use the following formulas to convert from rectangular to spherical coordinates:

ρ = √(x^2 + y^2 + z^2)

θ = arctan(y/x)

φ = arccos(z/ρ)

Plugging in the values (0, 3, -3), we get:

ρ = √(0^2 + 3^2 + (-3)^2) = 3

θ = arctan(3/0) = π/2 (since x = 0 and y > 0)

φ = arccos((-3)/3) = 5π/4 (since z < 0)

Therefore, in spherical coordinates, (0, 3, -3) is (3, π/2, 5π/4).

For part (b), we can use the same formulas to convert from rectangular to spherical coordinates:

ρ = √(x^2 + y^2 + z^2)

θ = arctan(y/x)

φ = arccos(z/ρ)

Plugging in the values (-6, 6, 6√2), we get:

ρ = √((-6)^2 + 6^2 + (6√2)^2) = √108

θ = arctan(6/(-6)) = π/4 (since x < 0 and y > 0)

φ = arccos((6√2)/√108) = π/2

Therefore, in spherical coordinates, (-6, 6, 6√2) is (√108, π/4, π/2).

The soda left in the bottle is 0.4 liters in a 2-liter bottle.

Let’s understand this with the concept of Ratio.

How does ratio work?

When two objects are related using numbers or amounts, the relationship is known as a ratio.

Initially, we are given that the bottle is 2 liters. From that, Sergio poured ⅘ of the soda.

So, the soda left is the initial quantity- the final quantity

= 2(initial quantity) - ⅘*2(final quantity)

Answer:

Neither of them are solutions unless you had a typo in the question.

Step-by-step explanation:

1) plug in the known values into both of the equations

First Coordinate:

y-x\(\leq\)-5
(1)-(0)\(\leq\)-5
1\(\leq\)-5 which is not true.
In this case, we do not need to plug in (0,1) into both of the equations because the coordinate cannot be a solution unless the coordinate works in BOTH of the equations.

Second Coordinate:

1)  y-x\(\leq\)-5
(-6)-(-1)\(\leq\)-5

(-6)+1\(\leq\)-5 -->    It becomes a +1 because two negatives make a positive

-5 \(\leq\)-5 - -> which means this is true because -5 is less than or equal to -5

2) y-2x>-5
(-6)-2(-1)>-5

-6(2)>-5
-12>-5 NOT TRUE

6x^2 + 4x -10

Step-by-step explanation:

Answer:

P(x)= x^3 - 4x^2 + 16x - 64

Step-by-step explanation:

First, let’s find all of the zeroes. If the question is asking for a degree 3 polynomial, than there has to be more than 2 zeroes. The complex conjugates theorem states that if a+bi is a zero, than a-bi has to be a zero as well. So if 4i is a zero, than -4i has to be a zero as well. By looking at the zeroes, you can write them as a linear factorization.

(x-4)(x+4i)(x-4i)

If you foil all of it, you will get x^3 - 4x^2 + 16x - 64.

The total combined area is 419m².

Length = 11m

Breadth = 9m

Height = 8m

Area of the room = Length × Breadth

                             = 11 × 9

                             = 99m

Area of the four walls =  2(l+b)h

                                    = 2(11+9)8

                                    = 16 × 20

                                    = 320m²

Therefore, Combined area = 99 + 320

To achieve her aim of selling 250% more cars than last year and get the incentive, she must sell 162 vehicles.

To find out how many cars the woman must sell to reach her goal, we first need to calculate what 250% of her sales from last year would be:

250% of 108 cars

= (250/100) x 108 cars

= 270 cars

So, to receive the bonus, the woman needs to sell more than 270 cars this year. However, the question asks how many cars she must sell to reach her goal of selling 250% as many cars as last year. Since she already sold 108 cars last year, we can calculate her goal as follows:

250% of 108 cars

= (250/100) x 108 cars

= 270 cars

Her goal is to sell 270 cars this year. Therefore, she needs to sell:

270 cars - 108 cars

= 162 cars

So, she must sell 162 cars to reach her goal of selling 250% as many cars as last year and receive the bonus.

Answer:

9.24

Step-by-step explanation:

Let's consider the statement P: "For all x, y ∈ Z, if xy = 0, then x = 0 or y = 0."

(a) The negation of P is: "There exist x, y ∈ Z such that xy = 0 and x ≠ 0 and y ≠ 0."

(b) The contrapositive of P is: "For all x, y ∈ Z, if x ≠ 0 and y ≠ 0, then xy ≠ 0."

(c) To prove P, consider the original statement. If xy = 0 and either x or y is nonzero, then the product of the nonzero integer with the zero integer must be zero. Since the product of any integer and zero is always zero, the statement P holds true.

(d) The converse of P is: "For all x, y ∈ Z, if x = 0 or y = 0, then xy = 0." To prove the converse, consider the two cases where either x or y is zero. If x = 0, then xy = 0 * y = 0. If y = 0, then xy = x * 0 = 0. In both cases, the product xy is zero, proving the converse to be true.

Answer:

\(f^{-1}(x)=\frac{\sqrt{x}}{4}\)

Step-by-step explanation:

The inverse of the function is the "opposite" of a function, so to speak. One can find it by treating it like a literal equation with 2 variables, one now has to solve for the other variable presnet. In other words, treat the therm (f(x)) like another variable in the equation. Now one has to solve for (x) in terms of (f(x)).

\(f(x)=4x^{2}\\\)

Manipulate the literal equation with inverse operations;

\(f(x)=4x^{2}\\\sqrt{}\\\\\\\sqrt{f(x)}=4x\\/4\\\\\frac{\sqrt{f(x)}}{4}=x\)

Now switch the variables;

\(f^{-1}(x)=\frac{\sqrt{x}}{4}\)

The \(f^{-1}(x)\) signifies that the written function is the inverse of the original function.

A and B have the same elements, the measure of AUB will be equal to the measure of B.

To show that if m*(A) = 0, then m*(AUB) = m*(B), we need to prove the following:
1. If m*(A) = 0, then A is a null set.
2. If A is a null set, then AUB = B.
3. If AUB = B, then m*(AUB) = m*(B).
Let's break down each step:
1. If m*(A) = 0, then A is a null set:
  - By definition, a null set has a measure of 0.
  - Since m*(A) = 0, it implies that A has no elements or its measure is 0.
  - Therefore, A is a null set.
2. If A is a null set, then AUB = B:
  - Since A is a null set, it means that it has no elements or its measure is 0.
  - In set theory, the union of a null set (A) with any set (B) results in B.
  - Therefore, AUB = B.
3. If AUB = B, then m*(AUB) = m*(B):
  - Since AUB = B, it implies that both sets have the same elements.
  - The measure of a set is defined as the sum of the measures of its individual elements.
  - Since A and B have the same elements, the measure of AUB will be equal to the measure of B.
  - Therefore, m*(AUB) = m*(B).
By proving these three steps, we have shown that if m*(A) = 0, then m*(AUB) = m*(B).

Answer: 272/3 OR 90.67

Step-by-step explanation:

First, turn the mixed fraction into an improper fraction. Using the times-addition method, you take the whole number (2) and multiply it by the denomitor (3). You get 6, and then add the numerator (2) to 6, getting 8, so th improper fraction of the first term is 8/3.

Then, you multiply 8/3 by 34. To do this, you do 8 times 34 divided by 3. 34 times 8 is 272, and then you divide it by 3. You don't get a whole number, so the answer could be written as 272/3 or 90.67
