Answer:

the answer is d

Step-by-step explanation:

he swims 80 feet below so thats gonna be a negative number. he then swims up 40 feet so you would be adding . so -80+ 40 = -120

The new location of the whale in relation to the equation of water's surface is -80 + 40 = -120 which correct option (D)

What is equation?

Equation is the defined as mathematical statements that have a minimum of two terms containing variables or numbers are equal.

Whale swims 80 ft below so it be a negative number.

Whale then swims up 40 ft so would be adding .

When the whale is 120 ft below the water's surface so it be a negative number.​

-80+ 40 = -120

Hence, the new location of the whale in relation to the equation of water's surface is -80 + 40 = -120

Answer:

−8<r≤3

Step-by-step explanation:

The final inequality of 24>−3r≥−9 is -8 <  r ≤ 3.

Given,

24>−3r≥−9

We need to solve this inequality.

We have,

< = less than

> = greater than

≤ = less than and equal

≥ - greater than and equal

If we change the sign we change the inequality.

Example:

2 > -1

Multiply -1 on both sides.

-2 < 1

We have,

24 > -3r ≥ -9

We can cancel the common factor.

3 x 8 > -3r ≥ - 3 x 3

8 > -r ≥ -3

Multiply - on all sides.

-8 < -(-r) ≤ -(-3)

-8 <  r ≤ 3

This means r values are between -8 and 3.

r = ( -8, 3]

Thus the final inequality of 24>−3r≥−9 is -8 <  r ≤ 3.

When we say 'as many as' or 'no more than', we mean 'less than or equal to' which means that a could be less than b or equal to b. But, when we say 'at least', we mean 'greater than or equal to'. Here a could be greater than b or equal to b.

Answer:

isolating the constant 1

Step-by-step explanation:

The first step in solving the equation via completing the square is to  isolate the constant.

The term completing the square method refers to one of the popular methods of solving quadratic equations that involves the addition of half of the square of the b term to both sides of the equation.

Given that an equation, x²-4x+1 = 0, we need to find the first step to solve this be using completing the square method,

So, according to the definition, we will add first isolate the constant,

Therefore,

x²-4x+1 = 0

x²-4x = -1

Now, we will add 4 to both the side,

x²-4x+4 = -1+4

(x+2)² = 3

x+2 = ±√3

x = √3-2 or x = -√3-2

Hence, the first step in solving the equation via completing the square is to isolate the constant.

Answer:

Irrational

Step-by-step explanation:

The number is called an irrational number.

These numbers have some distinct properties. The number of numbers after the decimal point is infinite. What this means is that it does not terminate. It keeps on repeating.

Also, these numbers cannot be represented as a ratio of two integers i.e two whole numbers. This is because they keep on going without termination.

Lastly is that these numbers do not repeat after decimal. What I mean by this is that they do not keep repeating a particular number after the decimal point. For example in cases like 2.33333; these are infinite too, but they can be represented by the ratio of two whole numbers and in such cases, they are not irrational in their own respect

Answer:

x = 109

Step-by-step explanation:

The figure has one pair of parallel sides and is a trapezoid.

The lower base angle is supplementary to the upper base angle on the same side, thus

x + x - 38 = 180 , that is

2x - 38 = 180 ( add 38 to both sides )

2x = 218 ( divide both sides by 2 )

x = 109

Answer:

35 ml of 28% acidic solution and 65ml of 45% acidic solution is to be used

Step-by-step explanation:

Let the number of ml of the 45% solution be x while that of the 28% solution be y

Mathematically;

x + y = 100 ••••••(i)

Furthermore

45% of x + 28% of y = 33.95% of 100

0.45x + 0.28y = 33.95 ••••••(ii)

From i,

x = 100-y

put this into ii

0.45(100-y) + 0.28y = 33.95

45 - 0.45y + 0.28y = 33.95

45 - 33.95 = 0.45y - 0.28y

11.05 = 0.17y

y = 11.05/0.17

y = 65

Recall

x = 100 - y

x = 100 - 65

x = 35 ml

x = 32

Step-by-step explanation:

So we are given the measures of two of the three interior angles. 98° and 50°. We are also given that the value of the third interior angle is equal to x°. Remember, the sum of the interior angles of a triangle is 180°. Knowing this, we can make the equation:

x + 98 + 50 = 180

Now we solve for x. Subtract 50 from both sides.

x + 98 = 130

Subtract 98 from both sides.

x = 32

So the value of x is 32.

Answer:

Your answer is going to be c The graph ofg(x)is the graph of f(x) translated 1 unit down.

Step-by-step explanation:

I just took the k12 4.08 quiz

The graph of​ g(x)​is the graph of f(x)​ ​​​​translated 1 unit down. Therefore, option C is the correct answer.

We need to find the relationship between the graph of f(x) and the graph of g(x)=f(x)−1.

A translation moves a shape up, down or from side to side but it does not change its appearance in any other way.

Translation Rules:

From the translation rule, g(x)=f(x)−1 is f(x) translated 1 unit down.

The graph of​ g(x)​is the graph of f(x)​ ​​​​translated 1 unit down. Therefore, option C is the correct answer.

Answer:

The smallest number is 114921 and the cube root of the result is 339

Step-by-step explanation:

The number 339 can be factored as:

339 = 3 * 113

Both factors are prime, thus to produce a perfect cube, we must multiply by each factor to the power of 2, that is:

3^2*113^2=114921

When we multiply 339 by 114921 we get 38958219, a perfect cube which cube root is 339.

Thus, the smallest number is 114921 and the cube root of the result is 339
