A square of side x is cut out of a larger square of side y. What is the area of the remaining
figure?
Answer:
The area of the remaining figure is [tex]y^2-x^2[/tex]
Step-by-step explanation:
Area of the Square Shape
Given a square of side length x, the area is calculated by the formula:
[tex]A_x=x^2[/tex]
It's given a square of side x is cut out of a larger square of side y. Please refer to the image below.
The area of the square of side length y is:
[tex]A_y=y^2[/tex]
The shaded area of the remaining figure is the difference between both areas:
[tex]A=A_y-A_x[/tex]
[tex]A=y^2-x^2[/tex]
The area of the remaining figure is [tex]\mathbf{y^2-x^2}[/tex]
Hi. I need help with these questions.
See image for question.
Step-by-step explanation:
Given
f(x) = 4x³ + 3x² - 2x - 1Divide it by the following:
(a) 2x + 1
4x³ + 3x² - 2x - 1 =(4x³ + 2x²) + (x² + 1/2x) - (5/2x + 5/4) + 1/4 =2x²(2x+1) + 1/2x(2x + 1) - 5/4(2x + 1) + 1/4 =(2x + 1)(2x² + 1/2x - 5/4) + 1/4Quotient = 2x² + 1/2x - 5/4
Remainder = 1/4
(b) 2x - 3
4x³ + 3x² - 2x - 1 = (4x³ - 6x²) + (9x² - 13.5x) + (11.5x - 17.25) + 16.25 = (2x -3)(2x² + 4.5x + 5.75) + 16.25Quotient = 2x² + 4.5x + 5.75
Remainder = 16.25
(c) 4x - 1
4x³ + 3x² - 2x - 1 = (4x³ - x²) + (4x² - x) - (2x - 1/2) - 3/2 =(4x - 1)(x² + x - 1/2) - 3/2Quotient = x² + x - 1/2
Remainder = - 3/2
(d) x + 2
4x³ + 3x² - 2x - 1 = (4x³ + 8x²) - (5x² + 10x) + (8x + 16) - 17 =(x + 2)(4x² - 5x + 8) - 17Quotient = 4x² - 5x + 8
Remainder = - 17
Step-by-step explanation:
Given
f(x) = 4x³ + 3x² - 2x - 1
Divide it by the following:
(a) 2x + 1
4x³ + 3x² - 2x - 1 =
(4x³ + 2x²) + (x² + 1/2x) - (5/2x + 5/4) + 1/4 =
2x²(2x+1) + 1/2x(2x + 1) - 5/4(2x + 1) + 1/4 =
(2x + 1)(2x² + 1/2x - 5/4) + 1/4
Quotient = 2x² + 1/2x - 5/4
Remainder = 1/4
(b) 2x - 3
4x³ + 3x² - 2x - 1 =
(4x³ - 6x²) + (9x² - 13.5x) + (11.5x - 17.25) + 16.25 =
(2x -3)(2x² + 4.5x + 5.75) + 16.25
Quotient = 2x² + 4.5x + 5.75
Remainder = 16.25
(c) 4x - 1
4x³ + 3x² - 2x - 1 =
(4x³ - x²) + (4x² - x) - (2x - 1/2) - 3/2 =
(4x - 1)(x² + x - 1/2) - 3/2
Quotient = x² + x - 1/2
Remainder = - 3/2
(d) x + 2
4x³ + 3x² - 2x - 1 =
(4x³ + 8x²) - (5x² + 10x) + (8x + 16) - 17 =
(x + 2)(4x² - 5x + 8) - 17
Quotient = 4x² - 5x + 8
Remainder = - 17

Answer:
900 black and white copies were printed.
Step-by-step explanation:
From the information provided, you know that they printed 9 black and white copies for every 2 colored copies and you can use a rule of three to find the amount of black and white copies that were printed if they printed 200 color copies:
9 black and white → 2 colored
x ← 200 colored
x=(9*200)/2=900
According to this, the answer is that 900 black and white copies were printed.

Step-by-step explanation:
Which equation represents a line which is perpendicular to the line y = 4/3x -7
A)3x + 4y = 8
B)4x – 3y = 24
C)4x + 3y = -6
D)4y - 3x = 12
Answer:
A)3x + 4y = 8
Step-by-step explanation:
Given expression;
y = [tex]\frac{4}{3} x[/tex] - 7
A line perpendicular to this will have negative inverse slope;
the slope of the given line = [tex]\frac{4}{3}[/tex]
perpendicular line = [tex]-\frac{3}{4}[/tex]
Now;
the equation of the line is;
y = [tex]-\frac{3}{4}[/tex] x - 7
multiply through by 4
4y = -3x - 28
4y + 3x = -28
Nolan says the relationship in the table is not proportional because the point (0, 0) does not appear in the table.
Which is the best way to explain to Nolan why he is incorrect?
A. A graph made from the table will be increasing, so it is proportional.
B. Not all proportional relationships contain (0, 0), so it could be proportional.
C. The points on the graph will have even y-coordinates, so it is proportional.
D. Even though (0, 0) is not in the table, the graph is a line through (0, 0), so it is proportional.
Answer: D. Even though (0, 0) is not in the table, the graph is a line through (0, 0), so it is proportional.
Step-by-step explanation:
The table is not included but this should be the correct answer.
Linear relationships which are proportional will have to pass through the origin which is (0,0). This does not mean that on the table, the points (0,0) have to be there.
Even if it does not explicitly appear in the table, so long as the line passes the origin, it is to be considered a proportional relationship. The (0,0) might not appear on the table because only a few points the line passed through were listed but if when the line is plotted, the line goes through (0,0), it is proportional.

Solve for x.
A) -7
C) 6
B) 9
D) 10
Answer:
A
Step-by-step explanation:
The segment BC joining the midpoints of 2 sides of the triangle is
Half the length of the third side, that is
x + 31 = 2(x + 19)
x + 31 = 2x + 38 ( subtract x from both sides )
31 = x + 38 ( subtract 38 from both sides )
- 7 = x → A
After multiplying, a calculator screen displays the answer shown below. How would you write this number in standard form? Enter your answer in the box. Include commas in your answer. 8.234 E14
Answer:
[tex]8.234 E14=8.234 \times 10^{14}[/tex]
Step-by-step explanation:
The given number is [tex]8.234 E14[/tex]
We need to write this number in standard form.
Any no is given in the standard form is given by :
[tex]N=a\times 10^b[/tex]
Where
a and b is real no and integer
It means,
[tex]8.234 E14=8.234 \times 10^{14}[/tex]
Hence, this is the required solution.

Answer:
C. x⁶y⁴/xy²
Step-by-step explanation:
Rearrange (x²y)(x⁴y³) to get
(x²x⁴)(yy³)
When multiplying numbers with exponents with the same base, you add the exponents.
So the equation above can be simplified even further to:
(x²⁺⁴)(y¹⁺³) --- (those are plus signs in between the exponents)
Simplify to
x⁶y⁴
Now you have the top of the equation simplified
so the answer is c

Answer:
5/6. Is this what u are looking for?
Step-by-step explanation:
Step 1 Simplify:2x(6)-19=-9 to 12x+-19=-9
Step 2 Add 19 to both sides: 12x-19+19=-9+19. You should get 12x=20
Step 3 Divide 12 on both sides: 12x/12=10/12
x=10/12. Simplified= x=5/6

The stopping distance (s) of a truck varies directly as the square of its speed (v). If a truck travelling at 50 mph requires 200 feet to stop, find the stopping distance for a truck travelling at 65 mph.
Answer:
The distance is 338ft
Step-by-step explanation:
Given
Represent distance with s and velocity with v:
When
[tex]s = 200\ ft[/tex]
[tex]v = 50mph[/tex]
Required
Determine the distance when velocity is 65mph
From the question, we understand that:
[tex]s\ \alpha\ v^2[/tex]
Convert to equation
[tex]s\ = kv^2[/tex]
Substitute 200 for s and 50 for v
[tex]200 = k * 50^2[/tex]
[tex]200 = k * 2500[/tex]
Make k the subject:
[tex]k = \frac{200}{2500}[/tex]
[tex]k = \frac{2}{25}[/tex]
To get s when v = 65.
Substitute 65 for v and 2/25 for k in [tex]s\ = kv^2[/tex]
[tex]s = \frac{2}{25} * 65^2[/tex]
[tex]s = \frac{2}{25} * 4225[/tex]
[tex]s = \frac{8450}{25}[/tex]
[tex]s = 338\\[/tex]
Hence, the distance is 338ft
