What is the size of the matix resulting from [4 -1 0] x [2 1 0 -3 -7 2 1 -5 2]

Answer:

  (d) ∛27 and 3³

Step-by-step explanation:

If f(x) and g(x) are inverse functions, then f(g(x)) = g(f(x)) = x. Here, it looks like we're to assume that the functions are of the form f(x) = root(x) or f(x) = x^power.

  a) these expressions evaluate to 25 and -25, so are additive inverses. We don't believe that is the intention of the question.

  b) f(x) = √x; g(x) = x². f(g(121)) = √(121²) ≠ √121

  c) f(x) = -∛(x); g(x) = (-x)³. f(g(64)) = -∛((-64)³) ≠ -∛64

  d) f(x) = ∛x; g(x) = x³. f(g(3)) = ∛(3³) = ∛27 . . . . . . these are inverse operations

Answer:

the area!!!

Step-by-step explanation:

2(a+b)h

to find b you have to know the base of the triangle. you may use pythagoras' theorem for that. you will then get 5ft as the base.

5ft + 48ft = 53ft.

put in the formula, the area is then

2(48+53)*13

am not with a calculator.... so sort it out....

I think you can get the rest with this...

Answer:

We will use the circumference formula to find the radius. Then the radius is 12. Now we will calculate the area of the the circle. Then the area of the circle is A= 144pi = 452.39 square units.

please mark brainliest

Step-by-step explanation:

Set the equation

[tex](x - 4) {}^{2} [/tex]

swap y and x

[tex](y - 4) {}^{2} = x[/tex]

[tex]y - 4 = {x}^{2} [/tex]

[tex]y = {x}^{2} + 4[/tex]

So the inverse is

[tex] {x}^{2} + 4[/tex]

The domain is [4, infinity)

The range is [0,infinity)

The domain of the inverse is [0, infinity)

The range is [4, infinity)

25% = 25% : 100% = 0,25 ← the end

60% = 60% : 100% = 0,6 ← the end

72,1% = 72,1% : 100% = 0,721 ← the end

7% = 7% : 100% = 0,07 ← the end

9,5% = 9,5% : 100% = 0,095 ← the end

66% = 66% : 100% = 0,66

Answer:

Step-by-step explanation:

Answer: 3880 miles

Step-by-step explanation:

Distance between Bill's house and his Aunt house = 485 miles

Distance traveled in one round trip = two times the distance between the Bill's house and his Aunt house

Distance traveled in one round trip = 2 x 485 = 970 miles

So, the distance traveled in 4 round trip = 4 x 970 = 3880 miles.

Thus, the distance traveled by the bill in 4 round trips is 3880 miles.

Answer:

210 is the answer to this question.

Step-by-step explanation:

linear equation formula

y = mx +b

where

b = y-intercept

m = slope

so 15 should be y=

[tex]y = \frac{7}{3} x - 3[/tex]

16 should be

[tex] \frac{2}{5} x - 5[/tex]

17 should be

[tex]y = - x + 3[/tex]

18 should be

[tex]y = 2x + 1[/tex]

Answer:

Will visit

explanation.

a verb is an action word. Visiting someone is doing an action, so will visit is the verb phrase.

The verb phrase in the given sentence is "will visit". Therefore, option D is correct.

A verb is a part of speech that typically describes an action or occurrence. It indicates a state of being. In a sentence, a verb is used to express the action or condition of the subject.

Verbs can take various forms, including present tense (e.g. "run"), past tense (e.g. "ran"), and future tense (e.g. "will run"). Verbs can also be regular, meaning that they follow a predictable pattern in their past tense form (e.g. "walk" becomes "walked"), or irregular, meaning that they do not follow a predictable pattern (e.g. "go" becomes "went").

Verbs can also be transitive or intransitive. The verb phrase in the given sentence is "will visit". Therefore, option D is correct.

Step-by-step explanation:

The pendulum swings over an angle of 2×(2°30') or 5° so we need to convert this to radian measure first:

Answer:

You can add 6 zeros to the end of the number 40 to get the product of 40 x 10^5.

Step-by-step explanation:

You can add 6 zeros to the end of the number 40 to get the product of 40×10⁵.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

Operators which let do a basic mathematical calculation

+ Addition operation: Adds values on either side of the operator.

For example 12 + 2 = 14

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 12 -2 = 10

* Multiplication operation: Multiplies values on either side of the operator

For example 12*2 = 24

We have powers of ten that are used to determine the product of 40×10⁵.

So, the product 40×10⁵ can be obtained by appending 6 zeros to the end of the integer 40.

Hence, You can add 6 zeros to the end of the number 40 to get the product of 40×10⁵.
