Answer:

[tex]cos(tan^{-1}(0))=1[/tex]

Step-by-step explanation:

Evaluate cos(tan^-1 0)

[tex]cos(tan^{-1}(0))[/tex]

We know that tan(0)=0

tan (0 degree)=0

[tex]tan^{-1}(0)=0[/tex]

Replace it in our problem

[tex]cos(tan^{-1}(0))[/tex]

[tex]cos(0)[/tex]

At 0 degree the cos value is 1

So co(0)=1

[tex]cos(tan^{-1}(0))=1[/tex]

Answer:

the correct answer is 1

The value of the digit 5 in the number 75 is 5. This is because in the number 75, 5 is in the ones place and thus represents 5.

The value of the digit 5 in the number 75 is actually 5 itself. In any two-digit number like 75, the place values are tens and ones. The first digit represents the tens place and the second represents the ones place. Therefore, in 75, the digit 7 represents 70 (as it is in the tens place) and the digit 5 represents 5 (as it is in the ones place). Hence, the value of the digit 5 in the number 75 is 5.

The rate of change of the function f(x)=(-4/5)x+8 is -4/5, as this is the slope of the linear function which is constant.

To find the rate of change of the function f(x)=-4/5x+8, we can identify the coefficient of the x term, which in this case is -4/5. This coefficient represents the slope of the line, which is the rate of change of the function.

Hence, the rate of change of the function f(x) is -4/5. No additional calculations are needed because the function is linear, and its rate of change is constant.

In terms of calculus, for linear functions, the rate of change is equal to the derivative, which for f(x)=-4/5x+8 is -4/5.

To find Taylor's home street address number, we can determine the value of each digit based on the given information and then calculate the sum.

In this problem, we are given that Taylor's home street address number has five digits.

We also know that two of the digits have values of 60,000 and 300, and the last digit is 9.

The value of each of the other digits is ten times the value of the digit on the right.

Let's break down the information we have:

Putting all the digits together, we get the address number: 60,000 + 300 + 3,000 + 30,000 + 9 = 93,309.

To find out how much carpet Maria needs for her square-shaped bedroom with each side measuring 12 feet, we can calculate the area of the room by using the exponential expression 12².

To find out how much carpet Maria needs for her square-shaped bedroom, we need to calculate the area of the room. Since each side of the square is 12 feet, we can use an exponential expression to find the area. The exponential expression is 12², which simplifies to 144 square feet.

The result is g'(x) = -2x.

Given g(x) =[tex]7 - x^2.[/tex]

Evaluate g(x+h)
=[tex]7 - (x+h)^2[/tex]
= [tex]7 - x^2 - 2xh - h^2.[/tex]

Compute g(x+h) - g(x)
=[tex][7 - x^2 - 2xh - h^2] - [7 - x^2][/tex]
= [tex]-2xh - h^2.[/tex]

Divide by h:
(g(x+h) - g(x)) / h
= [tex](-2xh - h^2) / h[/tex]
= -2x - h.

Take the Limit as h Approaches 0: As h approaches 0, the expression -2x - h approaches -2x.
Therefore, g'(x) = -2x.

So, the derivative of g(x) when h = 0 is -2x.

Final answer:

To multiply 6 and 42 using the distributive property, you break down 42 into 40 and 2, then multiply each part by 6 and add them together to get 252.

Explanation:

The distributive property in mathematics allows us to multiply a sum by multiplying each addend separately and then adding the products. April wants to multiply 6 by 42 using the distributive property. The correct way to do this using the distributive property is to break down 42 into 40 and 2, then multiply each by 6 and add the results. Therefore, the correct number sentence using the distributive property is:

6 × (40 + 2) = (6 × 40) + (6 × 2)

This simplifies to:

(6 × 40) + (6 × 2) = 240 + 12 = 252

So, 6 × 42 equals 252 when applied through distributive property.

Answer:

The remainder is 100.

Step-by-step explanation:

The divisor is [tex]x^2-8[/tex].

Dividend is [tex]x^4+36[/tex].

We have to find the remainder of

[tex]\frac{x^4+36}{x^2-8}[/tex]

It can be written as

[tex]\frac{x^4+36}{x^2-8}=\frac{x^4-64+64+36}{x^2-8}[/tex]

[tex]\frac{x^4+36}{x^2-8}=\frac{(x^4-64)+100}{x^2-8}[/tex]

[tex]\frac{x^4+36}{x^2-8}=\frac{(x^4-64)}{x^2-8}+\frac{100}{x^2-8}[/tex]

[tex]\frac{x^4+36}{x^2-8}=\frac{(x^2-8)(x^2+8)}{x^2-8}+\frac{100}{x^2-8}[/tex]       [tex][\because a^2-b^2=(a-b)(a+b)][/tex]

[tex]\frac{x^4+36}{x^2-8}=x^2+8+\frac{100}{x^2-8}[/tex]

Therefore the remainder is 100.

Answer:

(C)The two triangles may be congruent, but additional measurements are needed.

Step-by-step explanation:

It is given that QRS and FGH each have two sides that are 9 mm long that is QR=QS=9mm and FG=FH=9mm.

Thus, both the triangles that are QRS and FGH becomes the isosceles triangles.

Now, in order to prove that ΔQRS≅ΔFGH, we require more measurements as congruency can be proved only by SAS, SSS, ASA or AAA that is by using all the three sides of triangle or by using two sides one angle or by using two angles and one side or by using all the three angles.

Therefore, we need remaining side or angle in order to prove that ΔQRS is congruent to ΔFGH.

Hence,  option (C) is correct.

110/5 = 22, that is the middle number

now use the 2 numbers below that and the 2 numbers above that

so you have 20 + 21 + 22+ 23+24 = 110

Kirk needs 6 more songs to reach a total of 100, so the integer representing the number of songs he needs is +6.

Kirk needs 6 more songs to have a total of 100 songs for his MP3 player.

The integer to represent how many more songs Kirk needs is +6.

This is because an integer is a whole number (not a fraction or decimal) and can be positive, negative, or zero. In this case, since Kirk is adding songs to reach a total, we use a positive integer.

The +6 indicates that 6 more units (songs, in this context) are needed to reach the goal of 100.
