Given f(x)=(1)/(x), explain the how the graph of the nee function g(x)=(1)/(x-3)-5 transforms from the graph of f(x).

Answer:

16.5 cm²

Step-by-step explanation:

the measure of an exterior angle (32°) is found by dividing the difference between the measures of the intercepted arcs (54° and arc abject BF) by two.

32 = (BF - 54)/2

64 = BF - 54

arc angle BF = 64 + 54 = 118°

the area of that sector is

pi×r² × 118/360 = pi×4² × 118/360 = pi×16 × 118/360 =

= pi×2 × 118/45 =

= 16.47590814... ≈ 16.5 cm²

Answer:

The expression is a summation, or the sum of a sequence of terms. Each term is equal to 900 * (1.04)^n+1, where n starts at 1 and goes up to infinity.

To calculate this sum, we would need to find the limit of the sequence as n approaches infinity. However, finding the exact value of this sum is not possible and would require the use of mathematical tools like mathematical analysis.

To estimate the value, we can use a calculator or spreadsheet to calculate the sum for a finite number of terms and then see how the sum changes as we increase the number of terms. For example, if we calculate the sum for n = 1 to 100, we would get an estimate of the value. If we then calculate the sum for n = 1 to 200, we would get a closer estimate.

In this case, we can round the expression to the nearest integer, which would be 53.

Step-by-step explanation:

The standard deviation is used more frequently then the variance because  standard deviation is more stable and less sensitive to outliers.

The Standard Deviation and Variance are defined as two closely related measures of the spread or dispersion of a set of data.

The Variance is defined as average of squared differences from mean, while Standard Deviation is square root of variance.

The reason why the standard deviation is used more frequently than  variance is because the standard deviation is expressed in same units as the original data, whereas  the variance is expressed in squared units.

For Example, if we measure  heights of a group of people in inches, the standard deviation will be expressed in inches, whereas variance will be expressed in square inches.

Answer: The equation of a line in the form y = mx + b can be found using the slope-intercept form, where m is the slope of the line and b is the y-intercept. To find the equation of BC, we need to find the slope of the line and one point on the line.

The slope of the line can be found using the two points A and B. The slope of the line can be calculated using the formula:

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

where (x1, y1) and (x2, y2) are the coordinates of points A and B, respectively. Plugging in the values, we get:

m = (4 - (-1)) / (4 - (-3)) = 5 / 7

So the slope of the line BC is 5/7.

One point on the line BC is B = (4, 4), so we can use this point and the slope to find the y-intercept:

b = y - mx

where y and x are the y and x coordinates of point B, respectively. Plugging in the values, we get:

b = 4 - (5/7) * 4 = 4 - 20/7 = -16/7

So the equation of line BC in the slope-intercept form is:

y = (5/7)x - 16/7

To solve the given equations multiply equation 1 with - 2 and the solutions are x = 1 and y = 2.

In mathematics, the Elimination method is about deleting one of the words containing any of the variables to make the calculations easier.
To solve the equations, multiply or divide a number by the equation(s) until all of the variable terms' coefficients are the same.

The term is then eliminated or removed from the result by adding or subtracting from both equations.

Here we have

Equation 1: 2x - 5y = -8

Equation 2: 4x + 5y = 14  

We can multiply given equations as follows

To eliminate 'x' terms multiply the multiply equation 1 with -2

-2 × Equation 1 =>  - 4x + 10y = 16  ---- (Equation 3)  

Now add Equation (2) and Equation (3)

=> 4x + 5y - 4x + 10y = 14 + 16

=> 15y = 30

=> y = 2

Now substitute y = 2 in equation (2)

=> 2x - 5(2) = -8

=> 2x - 10 = -8

=> 2x = 2

=> x = 1  

Therefore,

If the spherical snowball is melting , then the rate at which the radius changing after 6.5 hours is 0.208 ft/h  .

A spherical snowball has volume = 260 ft³ that is melting at a rate of 11 cubic feet per hour, while remaining spherical.

We have to find the rate at which the radius is changing after 6.5 hours.

So , let "V" = volume of snowball, "r" = radius of snowball, and "t" = time.

Volume Of Sphere is  V = (4/3)πr³ and dV/dt = -11 ft³/h ;

So,  dr/dt when t = 6.5 hours. is dV/dt = (dV/dr)×(dr/dt)  ;

derivative of volume formula with respect to "r", we get:

⇒ dV/dr = 4πr²   ;

Substituting the given values in chain rule equation, we get:

⇒ -11 = (4/3)πr² × dr/dt  ;

⇒ dr/dt = -11/((4/3)πr²)

For  rate of change of the radius when t = 6.5 hours, we find the radius at that time.

The initial volume of the snowball = 260 ft³.

After 6.5 hours of melting at a rate of 11 ft³/h, the remaining volume will be:  V = 260 - (11 × 6.5) = 188.5 ft³   ;

So , V = (4/3)πr³

⇒ 188.5 = (4/3)πr³

⇒ r³ = (188.5 × 3 / (4π))   ;

≈ 3.55ft

Now we substitute r = 3.55 feet

⇒ dr/dt = -11/[(4/3)π(3.55)²]  ;

⇒ dr/dt ≈ -0.208 ft/h  ;

Therefore , the rate at which radius is changing after 6.5 hours is approximately 0.208 feet per hour and negative sign represents that radius is decreasing  .

The work required to stretch the spring an additional 3 inches is 10.125 foot-pounds.

We can use Hooke's law to find the force required to stretch the spring 4 inches from its natural length:

[tex]F = kx[/tex]

where F is the force in pounds, x is the displacement in inches, and k is the spring constant in pounds per inch (which we want to find).

Since 18 foot-pounds of work is required to stretch the spring 4 inches, we know that the work done is equal to the potential energy stored in the spring:

[tex]W = (1/2) k x^2[/tex]

Solving for k, we get:

[tex]k = (2W) / x^2[/tex]

Plugging in the values for W and x, we get:

[tex]k = (2 * 18) / (4^2) = 2.25[/tex]

So the spring constant is 2.25 pounds per inch.

Now we can use Hooke's law again to find the force required to stretch the spring an additional 3 inches:

[tex]F = kx[/tex]

= [tex]2.25 * 3[/tex]

= 6.75 pounds

Finally, we can find the work required to stretch the spring an additional 3 inches:

[tex]W = (1/2) k x^2[/tex]

= [tex](1/2) * 2.25 * 3^2[/tex]

= 10.125 foot-pounds

Therefore, the work required to stretch the spring an additional 3 inches is 10.125 foot-pounds.

With an area of 11,224 square feet and the dimensions of the screen if it is 30 feet longer than it is wide, the width of the screen is 91.5 feet, and the length of the screen is 121.5 feet.

Let's call the width of the screen "w". Then, the length of the screen would be "w + 30". The area of the screen is 11,224 square feet, so we can set up an equation:

w * (w + 30) = 11,224

Expanding the right side of the equation, we get:

w^2 + 30w - 11,224 = 0

We can use the quadratic formula to solve for w:

w = (-b ± √(b^2 - 4ac)) / 2a

Where a = 1, b = 30, and c = -11,224.

Plugging in the values, we get:

w = (-30 ± √(30^2 - 4 * 1 * -11,224)) / 2 * 1

= (-30 ± √(900 + 44,896)) / 2

= (-30 ± √(45,796)) / 2

= (-30 ± 213) / 2

Taking the positive solution, we get:

w = (183 / 2) = 91.5 feet

Hexagonal prism A has a surface area of 43 cm2.

A three-dimensional shape's surface area is the total area on its surface. A cuboid's surface area is calculated by adding the areas of each of its six rectangular sides. The cuboid's length, width, and height may all be identified, and the formula SA=2lw+2lh+2hw can be used to determine its surface area (SA).

The surface area of a hexagonal prism is given by the formula:

SA = 2B + PH

where B is the base's surface area, P is its perimeter, and H is the prism's height.

Since prism B is a dilation of prism A with a scale factor of 2, its surface area is four times the surface area of prism A. So we can write:

SA_B = 4×SA_A

where SA_B is the surface area of prism B and SA_A is the surface area of prism A

We are given that SA_B = 172 cm², so we can substitute this value into the equation above to find SA_A:

Lisa would need to score 97 on her 5th test.

Step-by-step explanation:

If Lisa has an average score of 82 on 4 tests, then the total sum of her scores would be 82 multiplied by 4, which is equal to 328.

If she wants an average final score of 85 over 5 tests, then the total sum of her scores needs to be 425 (i.e. 85 multiplied by 5).

To determine what she needs to get on her 5th test we need to subtract 328 from 425.

425 - 328 = 97

well, let's get the info first.

so going forth the Cheetah goes 70mph and going back it modestly does 40mph.

can we say that on average it did 55mph?

well, what's that?  on average means, that in total if we sum all units up and divide them evenly by relevant intervals, that's our average value.

well, let's see both intervals, on is forth and another is back 2 intervals, and the speed values are 70 and 40, so the average will really be (70 + 40) ÷ 2 = 55, that is an average of 55mph, so yes, we can say that.

A)

since an hour is 60 minutes, the Cheetah is really doing 70 miles per 60 minutes, or we can say

[tex]70\cdot \cfrac{miles}{~~\begin{matrix} hour \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~ }\cdot \cfrac{~~\begin{matrix} hour \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~ }{60~minutes}\implies \cfrac{70}{60}\cdot \cfrac{miles}{minutes} \implies 1.1\overline{66}\frac{miles}{minutes}[/tex]
