Step-by-step explanation:

For [tex]f(x)=3x-\frac{1}{2}[/tex], comparing it with slope-intercept form yields that the slope is [tex]3[/tex] and the [tex]y[/tex]-intercept is [tex]-1/2[/tex].

For the graphed function, the slope is [tex]\frac{-4-0}{-2-6}=\frac{1}{2}[/tex] and the [tex]y[/tex]-intercept is about [tex]-3[/tex].

Since the absolute value of the slope of the graphed function is less than that of [tex]f(x)[/tex], option B is correct.

We know that Lauren has 7/8 gallons of paint in total using simple mathematical operations.

A mathematical "operation" is the process of calculating a value utilizing operands and a math operator.

There are predefined rules associated with the math operator's symbol that must be applied to the supplied operands or numbers.

The five basic operations in mathematics are addition, subtraction, multiplication, division, and modular forms.

So, we know that:
Lauren has 3/4 gallons of paint.

She later added 1/8 gallon of more paint.

The total paint she has is:

3/4 + 1/8

2(3) + 1/8

6+1/8

7/8

Therefore, we know that Lauren has 7/8 gallons of paint in total using simple mathematical operations.

Answer:

40° and 110°

Step-by-step explanation:

the sum of the 4 angles in a quadrilateral = 360°

the ratio of 2 angles = 4 : 11 = 4x : 11x ( x is a multiplier )

sum the 4 angles, equate to 360 and solve for x

140 + 70 + 4x + 11x = 360

210 + 15x = 360 ( subtract 210 from both sides )

15x = 150 ( divide both sides by 15 )

x = 10

Then

4x = 4 × 10 = 40°

11x = 11 × 10 = 110°

the measure of the 2 angles is 40° and 110°

Answer: $336.77

Step-by-step explanation:

So, the fencing is technically the perimeter, so we have to find the perimeter of the semicircle.

Perimeter of a semicircle = 2(pi)(r)/2

So, divide 26 by 2 to get the radius, which is 13.

(We will use 3.14 for pi)

Then fill in the variables 2 x (3.14) x (13) / 2

So, when you multiply all the numbers you will get 81.64/2.

81.64/2 = 40.82 ft.

Now that you have found how much feet the fencing will be, multiply it by the cost.

40.82 x 8.25 = 336.765.

Round your final answer by the nearest hundredth which is 336.77.

Step-by-step explanation:

The area of the image is, 7396 square pixels.

what is area?

The measurement that expresses the size of a region on a plane or curved surface is called area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a shape or planar lamina.

Let x represent the length and the width of the image.

The area of the image and the border is represented by the expression

(x + 4)^2.  

Total area - area of image = Area of border

(x + 4)^2   -          x^2          =     704

⇒ x^2 + 8x + 16 - x^2 - 704 = 0

                             8x - 688 = 0

                                       8x = 688

                                         x = 86

The image will be 86 pixels by 86 pixels.

The area becomes  86*86 = 7396 square pixels.

Hence, the area of the image is, 7396 square pixels.

Step-by-step explanation:

Hence, the total gallons of water made use of in the park after the new ride is installed is 9.51*10⁵ gallons

The form of the container the water is contained in affects how much water is contained inside. You must know the length, breadth, and depth of a square or rectangular vessel in order to calculate its volume using the volume equation V=L*W*D, where L stands for length, W for width, and D for depth. The volume equation in this case reads: V= (r²)Dπ, where r stands for the radius, D for depth, and, or pi, is a constant value that is typically rounded to 3.14. To perform the same volume calculation for a circular vessel, you must know the vessel's depth and diameter or radius.

Given, the water park has water which is 8.6*10⁵ gallons.

We know that 10⁵ = 100000

Thus, 8.6*10⁵ = 860000

The new ride would use an additional 9.1*10⁴ gallons.

Again, 10⁴ = 10000

Thus, 9.1*10⁴ = 91000

Total water that would be required now is equal to the sum of the original water volume and the volume required by the new ride

= (860000+91000) gallons

= 951000 gallons

= 9.51*10⁵ gallons

Hence, the total gallons of water made use of in the park after the new ride is installed is 9.51*10⁵ gallons

The ratio of false positives to true positives is 3/49.

So, option B is correct.

A percentage is an expression that converts two ratios into an equal value. For instance, you may write the ratio as 1: 3 if there is 1 man and 3 women, meaning that 40% of the population is female and 14% is male. For any two numbers, the ratio formula is stated as a: b a/b. The percentage formula, on the other hand, is represented as a:b::c:da:b::c:da:b=cd. In mathematics, a ratio shows how many times one number is represented by another. For instance, if there are eight oranges and six lemons in a dish of fruit, the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3).

The percentage of false positives=3%

The percentage of true positives=49%

Ratio=3/49

Therefore, the ratio of false positives to true positives is 3/49.

Particular solution of the differential equation that satisfies the initial condition f'(s) = 10s - 4s³ , f(3) = 5 is f(s) =  5s² - s⁴ + 41.

We determine the particular solution to the differential equation. We do this by integrating the given differential equation and then applying the given initial condition. The power rule should be used for the given expression.

[tex]\int\ {x^{a} } \, dx[/tex] = [tex]\frac{x^{a+1} }{a+1} }[/tex]

we have given that,

f'(s) = 10s - 4s³

f(s) = ∫ f'(s)ds

     = ∫(10s - 4s³)ds

    = [tex]\frac{10s^{2} }{2} - \frac{4s^{2} }{4}+ C[/tex]

f(s) = 5s² - s⁴ + C

Now we will apply the initial condition,

f(3) = 5

⇒5(3)² - (3)⁴ + C =5

             -36 + C = 5

Answer:

A y = -3x + 1

Step-by-step explanation:

y = mx + b  When need to know the m (slope) and the b (y-intercept

The b is where the line crosses the y axis.  It crosses the y axis at 1.  The slope tells us the steepness of the line.  

If you start at the point (0,1) and move three units down and I unit to the right, you will be back on the line.  The slope is -3/1 which simplifies to -3

The break even point is x = 4  for cost C = 24x + 80 and Revenue R = 44x.

Cost is the amount of money spent by a business to produce or provide goods or services. It excludes the profit margin markup. Cost is the sum of money spent on making a thing or product, as seen from the seller's perspective.

Cost is defined as the total of real input costs and imputed costs associated with owner-supplied inputs.

The entire money derived from the sale of products or services pertaining to a business's core operations is referred to as revenue. Because it appears at the top of the income statement, revenue, which is also known as gross sales, is sometimes referred to as the "top line." A company's overall profits or profit are referred to as income, or net income.

The break-even threshold is reached when overall costs and total revenues are equal, leaving your small firm with no net benefit or loss. In other words, you've achieved the point in manufacturing when the income from a product matches the cost of manufacture.

At break even point cost equals revenue,

Therefore,

Cost = Revenue

⇒ 24x +80 = 44x

⇒ 20x = 80

⇒ x = 4.

The break even point is x = 4 .

The following expression represents a 2-scale factor vertical stretch, a transformation of 4 units left, and a transformation of 1 unit down:

g(x) = 2f(x + 4) - 1

A vertical stretch of scale factor K is expressed as follows for the general function f(x):

g(x) = Kf(x).

Horizontal translation:

A horizontal translation of N units for a general function f(x) is written as:

g(x) = f(x + N).

The shift is to the left if N is positive and the shift is to the right if N is negative.

Vertical translation:

A vertical translation of N units for a generic function f(x) is expressed as follows:

g(x) = f(x) + N.

When N is positive, there is an upward movement and N shifts downward if it is negative.

So, if we start with a function f(x) and we stretch it vertically with a scale factor of 2, we get:

g(x) = 2f(x)

Then we translate it into 4 units left:

g(x) = 2f(x + 4)

Then we translate 1 unit down:

g(x) = 2f(x + 4) - 1

This is the equation for the transformation.
