Eddie has saved up $45 to purchase a new camera from the local store. The sales tax in his county is 7% of the sticker price. Write an equation and solve it to determine the value of the highest priced camera Eddie can purchase with his $45, including the sales tax. Round your answer to the nearest penny.
x − 0.07x = 45; $48.39
0.7x = 45; x = $64.29
7x = 45; x = $6.43
x + 0.07x = 45; x = $42.06
tax gets added to the price of the camera
so the equation is:
x + 0.07x = 45; x = $42.06

What is the remainder when (x^4+36) is divided by (x^2-8)
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.

Kirk bought songs for his MP3 player. He needed 6 more songs to have a total of 100. Write an integer to represent how many more songs Kirk needs. I NEED HELP!!!!!!!
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.

Find the coordinates of P so that P partitions the segment AB in the ratio 1:1 if A(13,1)A(13,1) and B(−5,−3)B(−5,−3)
The coordinates of point P that partitions the segment AB in the ratio 1:1 are (4, -1). The calculation is done using the segment partition formula.
Explanation:To solve this problem, we use the formula for finding the point that divides a line segment into a given ratio. The formula is P(x, y) = ((x1*m2 + x2*m1)/(m1+m2), (y1*m2 + y2*m1)/(m1+m2)). Here, points A and B are (13,1) and (-5,-3) respectively, and the ratio m1:m2 is 1:1.
So applying the formula, we have P(x, y) = ((13*1 + -5*1) / (1+1), (1*1 + -3*1) / (1+1)) = (8/2, -2/2) = (4, -1).
So, the coordinates of point P that partitions the segment AB in the ratio 1:1 are (4, -1).

To find the coordinates of point P that bisects the segment AB in the ratio 1:1, we use the midpoint formula. Substituting the values of points A(13,1) and B(-5,-3) into the formula gives us P(4,-1).
Explanation:The student wants to find the coordinates of point P that would bisect the line segment AB in a 1:1 ratio. Since the ratio is 1:1, point P is the midpoint of the segment. To find the coordinates of the midpoint P, we need to calculate the average of the x-coordinates and the y-coordinates of points A and B.
Using the formula of a midpoint, M(x, y) = [ (x1+x2)/2 , (y1+y2)/2 ], let's substitute the coordinates of points A(13,1) and B(-5,-3).
P(x, y) = [ (13-5)/2 , (1-3)/2 ]
Therefore, the coordinates of point P that partitions the segment AB in the ratio 1:1 is P(4, -1).

Find the rate of change of the function f(x)=-4/5x+8
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.

Given the function g(x)=7-x^2, evaluate g(x+h)-g(x)/h , h=0
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.
April wants to multiply 6 and 42 using the distributive property. Which of the following number sentences shows how she could do it?
6 × 42 = 42 × 6
6 × (40 + 2) = (6 × 40) + 2
(6 × 42) × 1 = 6 × (42 × 1)
6 × (40 + 2) = (6 × 40) + (6 × 2)
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.
Okay, I am stumped on a 4th grade math problem. Help! Taylor's home street address number has five digits. Two digits have values of 60,0000 and 300. The last digit is 9. The value of each of the other digits is ten times the value of the digit on the right. What is Taylor's home street address number?
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.
Explanation: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:
The first digit is 60,000.The second digit is 300.The third digit is 10 times the value of the second digit, so it's 10 * 300 = 3,000.The fourth digit is 10 times the value of the third digit, so it's 10 * 3,000 = 30,000.The last digit is 9.Putting all the digits together, we get the address number: 60,000 + 300 + 3,000 + 30,000 + 9 = 93,309.
what is the value of the digit 5 in the number 75
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.
Explanation: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.

(I NEED THIS ASAP PLEASE)Jermaine knows that QRS and FGH each have two sides that are 9 mm long. What statement best describes the two triangles?
1)The two triangles are congruent because there are two pairs of congruent corresponding sides.
2)The two triangles are congruent because both triangles are isosceles with 9 mm sides.
3)The two triangles may be congruent, but additional measurements are needed.
4)The two triangles may be congruent, but additional information is needed about the orientation of the figures.
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.
