Answer:

y=3x-2

Step-by-step explanation:

For this problem, you can use the point-slope formula: y-y1=m(x-x1), with x1 and y1 being from the given coordinate, and m being the slope (which is 3 that can be seen in the equation). Since we're finding a line that is parallel to this line, the slopes of both equations are the same.

y-(1)=3(x-1)

y-1=3x-3

y=3x-2

Check:

(1)=3(1)-2

1=3-2

1=1

\(y=3x-2\)  is an equation of a line that is parallel to \(y = 3x - 9\) and passes through the point \((1, 1).\)

What is equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

What is Parallel lines?

In geometry, parallel lines are coplanar straight lines that do not intersect at any point. Parallel planes are planes in the same three-dimensional space that never meet.

According to question, we have to write an equation of a line that is parallel to \(y = 3x - 9\)  and passes through the point \((1, 1)\)

Since, the line passes through \((1,1)\) and have slope\(=3\)

So, \(y-(1)=3(x-1)\)

⇒      \(y-1=3x-3\)

⇒            \(y=3x-2\)

Hence, we can conclude that \(y=3x-2\)  is an equation of a line that is parallel to \(y = 3x - 9\) and passes through the point \((1, 1).\)

Answer:

Options (B), (D), and (E) are correct.

Step-by-step explanation:

The given best fit curve for the collected data is

\(y=73.6 - 67.8x\cdots(i)\)

Where x is the number of hours spent driving and y is the distance of distributer, in miles, from the retailer.

As the driver starts recording the time when he starts from the retailer, so at the starting time, x=0, the driver is at the retailer.

So, putting x=0 in the given equation (i) to get the distance between the distributor and retailer, we have

\(y =73.6 - 67.8\times 0\)

\(\Rightarrow y= 73.6\) miles.

So, the distributor is 73.6 miles away from the retailer.

From equation (i), as x (time) increases the value of y (distance) decreases.

So, The distance from the retailer decreases with time.

Now, obtaining the rate of change the distance,y, from quation  (i), with respect to time,x, to get the speed of the truck, we have

\(\frac {dy}{dx}=-67.8\) mile/hour

Negative sign shows that the distance is decreasing, taking the magnitude of the rate of change of distance with respect to time to get the speed,

speed \(= | dy/dx |= | -67.8 | = 67.8\) miles/hour

So, the speed of the truck is 67.8 miles per hour.

Hence, options (B), (D), and (E) are correct.

Using linear function concepts, it is found that the correct options are:

B. The distance from the retailer decreases with time.

D. The distributor is 73.6 miles away from the retailer.

E. The truck is traveling at a rate of 67,8 miles per hour

A linear function is modeled by:

\(y = mx + b\)

In which:

In this problem, the distance, in miles, after x hours driving is modeled by:

\(y = 73.6 - 67.8x\)

m∠V = 60°, m∠U = 90°, m∠W = 30°

Step-by-step explanation:

hope this helps y'all out

The angle measures of triangle VUW are m∠V = 90°, m∠U = 60°, m∠W = 30°

From the given diagram;

According to the rule:

sin <V = opp/hyp

sin <V = 3√3/6

sin <V = √3/2

<V = 60 degrees

Since the triangle is right-angled, the measure of m<U is 90 degrees

Also, the sum of interior angle of a triangle is 180 degrees, hence;

60 + 90 + <W = 180

<W = 180 - 150

<W =  30 degrees

Hence the angle measures of triangle VUW are m∠V = 90°, m∠U = 60°, m∠W = 30°

Answer:

g(x) = \(12.(\frac{3}{4})^x\)

Step-by-step explanation:

Exponential function g has been represented by the table attached,

Equation of the exponential function is,

g(x) = \(a.(b)^x\)

Now we substitute the values of x and g(x) from the table,

For a point (0, 12),

12 = \(a(b)^0\)

a = 12

For another point (1, 9),

9 = \(a.(b)^1\)

9 = a × b

9 = 12 × b

b = \(\frac{9}{12}\)

b = \(\frac{3}{4}\)

Therefore, equation of the exponential function will be,

g(x) = \(12.(\frac{3}{4})^x\)

Step-by-step explanation:

If the estimate of the population standard deviation is 8, the sample size is 62

In this question, you want to estimate the population mean with 95% confidence with a margin of error of 2.

if the estimate of the population standard deviation is 8, we need to find the sample size.

here, α = (1 - 0.95)/2

         α = 0.025

Now, we have to find z in the Ztable as such z has a pvalue of 1 - α

so, z = 1.96

Now, to find the margin of error M we have formula

M = z * σ/√n

2 = 1.96 * 8/√n

√n = 1.96 * 4

√n = 7.84

n = 61.47

n ≈ 62

Therefore,  if the estimate of the population standard deviation is 8, the sample size is 62

The least common denominator for the rational expression is (x + 8) (x + 2) (x - 1)

What is LCD in Rational Expression ?

The denominators' smallest common multiple is called the LCD. We factor the expressions and multiply each unique factor to obtain the LCD of two rational expressions.

The given expression is,

(x + 2) / (x² + 7x - 8) , (x - 6) / (x² +10x + 16)

Let,

(x + 2) / (x² + 7x - 8)     --------eq(i)

(x - 6) / (x² +10x + 16)   ----------- eq(ii)

First take the denominator of eq(i)

The denominator is = x² + 7x - 8

We know, this is quadratic equation so just solve this equation

⇒ x² + 8x - x - 8

⇒ x(x + 8) - 1(x + 8)

⇒ (x - 1) (x + 8)

Next, take the denominator of eq(ii)

The denominator is = x² + 10x + 16

And, this is also a quadratic equation so the factors are,

⇒ x² + 8x + 2x + 16

⇒ x(x + 8) + 2(x + 8)

⇒ (x + 2) (x + 8)

So, after solving both the denominators we get the factors ,

(x - 1) (x + 8) and (x + 2) (x + 8)

As, we see (x + 8) is common just write it once and else terms write as it is,

LCD = (x + 8) (x - 1) (x + 2)

Therefore, the least common denominator for the rational expression is (x + 8) (x + 2) (x - 1)
