Step-by-step explanation:

its because for the graph there is 90 and it has a point and when i used a calc i put the points and the a=18 so 90 eould be 18 again this what i think i am not really AMAZING at it but i get some of it for ex the chart equals it only equals a=5

Step-by-step explanation:

The variance of the set  { 2 , 6 , 8 , 3 , 7 , 9 , 1 , 4 } is 7.5

What is Variance?

Variance is the expectation of the squared deviation of a random variable from its population mean or sample mean. Variance is a measure of dispersion, meaning it is a measure of how far a set of numbers is spread out from their average value

Given data ,

The set S = { 2 , 6 , 8 , 3 , 7 , 9 , 1 , 4 }

Step 1 :

To calculate the mean ,

Mean = Sum of Observations / Number of Observations

         = ( 2 + 6 + 8 + 3 + 7 + 9 + 1 + 4 ) / 8

         = 40 / 8

         = 5

Step 2 :

Take each difference from mean and square it

( 2 - 5 )² = 9

( 6 - 5 )² = 1

( 8 - 5 )² = 9

( 3 - 5 )² = 4

( 7 - 5)² = 4

( 9 - 5 )² = 16

( 1 - 5 )² = 16

( 4 - 5 )² = 1

And Sum of 9 + 1 + 9 + 4 + 4 + 16 + 16 + 1 = 60

Step 3 :

Variance = The mean of squared difference

               = 60 / 8

               = 7.5

Hence , the variance is 7.5

Step-by-step explanation:

Derivative of cos(x)=-sin(x)

Derivative of e^x=e^x

Derivative of cos(x)-e^x= - sin(x)-e^x

plug in 0 to the spots of x and you will get 1 because sin(0) is 0 e^0 is 1

Step-by-step explanation:

Second rectangle and third rectangle are resulting rectangles scale drawings of one another

The area of Rectangle is length times of width.

Given,

Gayla draws a rectangle.

Second rectangle:

Jared then draws a different rectangle by increasing both the length and the width by 5%.

Third rectangle:

Lyda draws a third rectangle by increasing both the length and the width of Gayla’s by 5 inches.

Let us assume 1 inches as 1 percentage.

So second rectangle and third rectangle are resulting rectangles scale drawings of one another

Hence,  second rectangle and third rectangle are resulting rectangles scale drawings of one another

Answer:

SI is used in most places around the world, so our use of it allows scientists from disparate regions to use a single standard in communicating scientific data without vocabulary confusion.

Answer:

(1,3)

Step-by-step explanation:

Answer:

The values of a,b,c and d are as follows:

a = 3, b = -12, c = -5, d = 10

Step-by-step explanation:

Given functions are:

[tex]f(x) = 4x^3-12x^2+10\\g(x) = x^3-2x^2+5x[/tex]

We have to find the value of f(x) - g(x). This means we have to subtract function g(x) from function f(x)

So,

[tex]f(x) - g(x) = (4x^3-12x^2+10)-(x^3-2x^2+5x)\\= 4x^3-12x^2+10-x^3+2x^2-5x[/tex]

Combining alike terms

[tex]= 4x^3-x^3-12x^2+2x^2-5x+10\\= 3x^3-10x^2-5x+10[/tex]

Now it was given that:

f(x)- g(x)= ax^3+bx^2+ cx+d

By comparing both we get

a = 3, b = -12, c = -5, d = 10

Hence,

The values of a,b,c and d are as follows:

a = 3, b = -12, c = -5, d = 10

Step-by-step explanation:

cos18=29/x --> reciprocate for simplicity : 1/cos18=x/29 --> solve for x

Answer: d. 2 hrs

Step-by-step explanation:

Let x = Time taken(in hours) to fly 470 mi to New Orleans. (Shorter leg)

Then Time taken to fly 705 mi to Atlanta= x+1 (longer leg)

Since  the plane flew at the same rate for the entire trip.

i.e. Speed 705 mi to Atlanta = Speed to fly to New orleans

[tex]\Rightarrow\ \dfrac{705}{x+1}=\dfrac{470}{x}\ \ \ \ \ \ \ [\text{Speed}=\dfrac{\text{Distance}}{\text{Time}}]\\\\\Rightarrow\ 705x=470(x+1)\\\\\Rightarrow\ 705x=470x+470\\\\\Rightarrow\ 705x-470x=470 \\\\\Rightarrow\ 235x=470\\\\\Rightarrow\ x=\dfrac{470}{235} \\\\\Rightarrow\ x=2[/tex]

hence, the flying time for the shorter leg = 2 hours

So (d) is the correct option.

Answer:

1/4

Step-by-step explanation:

7 divided by 24 = 4 so it gets reduced to 1 and then 1/4

The solution is: 1/4  is the simplified form of the fraction 7/28.

Here, we have,

given that,

the fraction is: 7/28

now, we divide each fraction numerator and denominator by a common divisor of them,

here, we know that,

7 * 1 = 7

7*4 = 28

so, the gcf of 7 and 28 = 7

we divide each fraction numerator and denominator by a common divisor 7,

we will get:

7/28 = 1/4

7 divided by 28 = 4 so it gets reduced to 1 and then 1/4.

Hence, The solution is: 1/4  is the simplified form of the fraction 7/28.

Their bills will never be the same because the toppings cost the same.

Question must probably wants to know the number of toppings it would take for their bills to be equal.

Assume the number of toppings is x, Dennis's bill will be:

= Cost of Pizza + Cost of toppings x number of toppings

= 16.50 + 2x

Sheng's bill will be:

= 13.25 + 2x

Equate their bills to find the number of toppings that would equate their costs:

16.50 + 2x = 13.25 + 2x

16.50 - 13.25 ≠ 2x - 2x

3.25 ≠ 0

In conclusion, their bill will never be the same because the toppings are the same price.

Answer: [tex]\frac{6}{2}[/tex]

Step-by-step explanation:

1. Use this [tex]\frac{f(b)-f(a)}{b-a}[/tex] to find the average rate of change

2. Average rate of change = [tex]\frac{f(8)-f(6)}{8-6}[/tex]

3. [tex]f(8) = - 4[/tex] and [tex]f(6) = -10[/tex] (To find these you will need to look at the points on the graph. So the points (8,-4) and (6,-10))

4. Replace -4 to f(8) and -10 to f(6)

5. So it will look like[tex]\frac{-4-(-10)}{8-6}[/tex]
