Find the volume of this irregular figure.

Answer:

1/4

Step-by-step explanation:

To find the slope of a line from two points we use

m = (y2-y1)/(x2-x1)

m = (3-2)/ (3--1)

   = (3-2)/(3+1)

  =1/4

Step-by-step explanation:

A(-1,2) and B(3,3) then AB=(4,1).

Normal vector

n=(-1,4)

Our line contains point A(-1,2) and has normal vector n=(-1,4) is

[tex](d) : - 1(x + 1) + 4(y - 2) = 0[/tex]

[tex](d ): - x - 1 + 4y - 8 = 0[/tex]

[tex](d) : - x + 4y - 9 = 0[/tex]

Substitute all values for x and y into their placement

y<1-6x

(1)<1-6(-1)

1<7

The coordinate pair is (-1,1)

Exact Form: √3/3

Decimal Form: 0.57735026

sorry if i got it wrong, i tried my best on this :)

The value of the expression tan π/6 is √3/3 or approximately 0.5774.

The value of the expression tan π/6 is √3/3 or approximately 0.5774.

To find this value, we can remember that tan θ = sin θ / cos θ. So, tan(π/6) = sin(π/6) / cos(π/6).

Thus, tan(π/6) = (√3/2) / (1/2) = √3/3.

Answer:

(-4, -2)

Step-by-step explanation:

The x-coordinate would stay the same, but the y-coordinate would be halved.  Thus, the corresponding point would be (-4, -2).

Answer:

A)

Step-by-step explanation:

The expression (a + b)(x + y) is not equivalent to (a + x)(b + y). When the terms are distributed, (a + x)(b + y) yields a different result compared to the original expression.

The expression (a + b)(x + y) is equivalent to a(x + y) + b(x + y) and (b + a)( y + x) because the order of addition in each element doesn't change the overall result. However, the expression (a + x)(b + y) is not equivalent to the original expression.

To understand why, let's distribute the terms in each equivalent expression:

(a + b)(x + y) = ax + ay + bx + by

(b + a)( y + x) = ay + ax + by + bx = ax + ay + bx + by

a(x + y) + b(x + y) = ax + ay + bx + by

As you can see, all these three expressions give the same result when distributed. But, if we now distribute the terms in (a + x)(b + y):

(a + x)(b + y) = ab + ay + bx + xy

It's clear that it does not yield the same result. Thus, option A) (a + x)(b + y) is not equivalent to the original expression (a + b)(x + y).

Answer:

h = 6 cm  

l = (32-2(6)) =  20 cm

w = (40-2(6)) = 28 cm

Step-by-step explanation:

Given in the question a piece of cardboard having dimensions 32 by 40

Suppose we cut square of length x

When you cut square corners from a piece of cardboard, two sides are 32-2x, and other two sides are 40-2x lengths

Formula for the volume of box

v = height * length  * width

v = x  (32-2x)  (40-2x)

v = 4x³ - 144x² + 1280x

Find derivative and equal it to 0

dv/dx = 4(3)x² - (2)144x + 1280

      0 = 12x² - 288x + 1280

x1 = 18.110

x2 =5.88

Select x and plug value of x to find dimension

(32-2x) > 0

2x < 32

 x < 16

so domain say that x should be less than 16 which means x = 5.88 ≈ 6 cm

h = 6 cm  

l = (32-2(6)) =  20 cm

w = (40-2(6)) = 28 cm

Answer:

r = 17 units

Step-by-step explanation:

The radius is the distance from the centre (- 7, - 1) to the point on the circle

(8, 7)

Use the distance formula to calculate the radius (r)

r = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 7, - 1) and (x₂, y₂ ) = (8, 7)

r = [tex]\sqrt{(8+7)^2+(7+1)^2}[/tex]

  = [tex]\sqrt{15^2+8^2}[/tex]

  = [tex]\sqrt{225+64}[/tex]

  = [tex]\sqrt{289}[/tex] = 17 units

The simplified expression is 3.5r - 7.

To simplify the expression 6.4r - 7 - 2.9r, first, combine like terms by subtracting the coefficients of 'r'.

This yields (6.4 - 2.9)r. Simplifying the coefficients gives 3.5r. Then, subtract 7. Therefore, the simplified expression is 3.5r - 7.

This means that when you distribute the 'r', you multiply it by 3.5, then subtract 7 from the result.

The simplified expression is 3.5r - 7.

0.24 = 24%

The percentage of females polled supported Wilson is about 44%

Given:

Total frequency of females polls = 0.54

Frequency of polls got by Wilson = 0.24

We have to find the percentage of female polls supported Wilson.

[Percentage Polls) × (Total frequency of females polls)] / 100 = Frequency of polls got by Wilson

⇒ Percentage polls = (0.24 × 100) / 0.54

⇒ Percentage polls = 44.44%

Therefore, the percentage of females polled supported Wilson is about 44%.

No 5/8 is bigger because half of 8 is 4 and 5 is greater than 4

In comparing 1/2 gallon and 5/8 gallon, using equivalent fractions shows that 5/8 gallon is larger than 1/2 gallon.

In the comparison of 1/2 gallon and 5/8 gallon, it's important to remember that fractions provide a way of representing parts of a whole. With fractions, the numerator represents the part while the denominator represents the total parts. So here, the fraction 5/8 represents 5 parts of a total 8 parts, where 1 gallon is considered the 'whole' or 'total' amount.

To determine if 1/2 is greater or less than 5/8, we want to make the denominators the same for comparison. Multiply the numerator and the denominator of the first fraction (1/2) by four to get it to the same denominator as the second one. This results in 4/8 for the first fraction.

Now, comparing 4/8 and 5/8, we find that 5/8 is greater than 4/8. Therefore, 5/8 gallon is indeed more than 1/2 gallon.

Answer:

function defined on different intervals by different domain rules

hope it helps

The terms absolute value, continuous function, step function, and piecewise-defined function are matched with their respective definitions: the absolute value measures distance from zero, a continuous function has a graph without breaks, a step function has a graph with horizontal steps, and a piecewise-defined function has different rules for different intervals.

Matching Vocabulary to Definitions

Let's match each mathematical term to its correct definition:

Absolute value - This is the function whose output equals the input for non-negative numbers, and whose output is the opposite of a negative input. It can be thought of as the distance from zero on the number line, regardless of direction.

Continuous function - A function whose graph has no breaks is known as continuous. It means you can draw the function without lifting your pen off the paper, indicating it has no jumps or holes.

Step function - Such a function has a graph that consists of horizontal line segments. The value of the function changes in 'steps' rather than smoothly.

Piecewise-defined function - When a function is defined on different intervals by different domain rules, it is known as a piecewise-defined function. It's like having multiple functions strung together each applicable to different parts of the domain.

Apply difference of two squares to get:

[tex] ( {x}^{2} + 9)({x} - 1)(x + 1)[/tex]

Answer:

[tex](x^2+9)(x-1)(x+1)[/tex]

Step-by-step explanation:

We would need to let u = x^2 and use middle term factorization first. let's do this:

if u = x^2, then x^4 + 8x^2 – 9 would be

u^2+8u-9

Middle term factorization of this is:

(u+9)(u-1)

now replacing back u = x^2:

(x^2+9)(x^2-1)

Using the formula a^2 - b^2 = (a+b)(a-b), we can write (x^2 - 1) as (x+1)(x-1).

So, the final factored form is:  (x^2+9)(x-1)(x+1)

The angles of a right angled triangle, 30°, 60° and 90° then sides are in the ratio, 1: √3 : 2

To find the value of variables

From the figure we can see 2 right angled triangle with angle 30, 60 and 90

we get, d= 5 then b = 5√3

b = 5√3  the c = 5√3 * √3 = 15

and a = 2 * 5√3 = 10√3

Therefore the correct answer is option C

a = 10√3, b = 5√3, c = 15 and d = 5

Answer:

d.[tex]a=10\sqrt3,b=5\sqrt3,c=15,d=5[/tex]

[tex]\frac{d}{10}=cos 60^{\circ}[/tex]    ([tex]cos\theta=\frac{base}{hypotenuse}[/tex])

[tex]d=\frac{1}{2}\times 10=5[/tex]

[tex]\frac{b}{a}=sin30^{\circ}[/tex]

[tex]\frac{5\sqrt3}{a}=\frac{1}{2}[/tex]

[tex]a=10\sqrt3[/tex]

[tex]\frac{b}{c}}=tan 30^{\circ}[/tex]   ([tex]tan\theta=\frac{p}{b}[/tex])

[tex]\frac{5\sqrt3}{c}=\frac{1}{\sqrt3}[/tex]
