The average rate of change for an exponential function grows by equal [blank1] per unit interval.

Answers

Answer: The average rate of change for an exponential function grows by equal factor per unit interval.

Step-by-step explanation:

The general exponential equation for growth is given by:-

[tex]y=Ab^x[/tex], where

A= initial value

b= Multiplicative growth rate

x = time period

For each value of x, the value of y increases by an equal value of multiplicative factor ( b).

For example: at x=0 , [tex]y=A[/tex]

at x=1, [tex]y=Ab[/tex]

at x= 2, [tex]y=Ab^2[/tex]

Hence, the average rate of change for an exponential function grows by equal factor per unit interval.

hi :) how to do 10(iii) ?:)

Answers

(i) AB and DC are parallel, so the lines containing these sides have the same slope.

The line containing AB has slope (2 - (-1))/(10 - 4) = 3/6 = 1/2.

Use the point-slope formula to find the equation of the line containing CD:

[tex]y-8=\dfrac12(x-12)\implies y=\dfrac x2+2\implies\boxed{2y=x+4}[/tex]

AP is perpendicular to both AB and CD, and perpendicular lines have slopes that are negative reciprocals of one another. This means the line containing AP has slope -1/(1/2) = -2. Using the point-slope formula again, the equation of the line containing AP is

[tex]y-(-1) = -2(x-4)\implies \boxed{y=-2x+7}[/tex]

(ii) D lies on the x axis, so its y-coordinate is 0. Find the x-coordinate by plugging y = 0 into the equation for the line containing CD:

[tex]2\cdot0=x+4\implies x=-4[/tex]

So D is the point (-4, 0).

P is the intersection of the lines containing CD and AP, so set them equal and solve for x and y :

[tex]y=\dfrac x2+2\text{ and }y=-2x+7[/tex]

[tex]\implies\dfrac x2+2=-2x+7\implies 5x=10\implies x=2[/tex]

[tex]\implies y=-2\cdot2+7\implies y=3[/tex]

So P is the point (2, 3).

(iii) For ASBC to be a parallelogram, we need to find the coordinates of S such that the line containing AS is parallel to the line containing BC, and the line containing SC is parallel to the line containing AB.

BC has slope (8 - 2)/(12 - 10) = 6/2 = 3. Then the line containing AS has equation

[tex]y-(-1)=3(x-4)\implies y=3x-13[/tex]

We already know AB has slope 1/2. Then the line containing SC has equation

[tex]y-8=\dfrac12(x-12)\implies y=\dfrac x2+2[/tex]

S is the intersection of these two lines:

[tex]3x-13=\dfrac x2+2\implies\dfrac{5x}2=15\implies5x=30\implies x=6[/tex]

[tex]\implies y=3\cdot6-13\implies y=5[/tex]

So S is the point (6, 5), and *not* (2, -7) as the answer key suggests. In fact, (2, -7) is located lower than the point A and slightly to the left; if you draw that point and connect it to the other three, there's no way to get a parallelogram.

(iv) Find the lengths of AB, CD, and AP. Then the area is (AB + CD)*AP/2.

[tex]AB=\sqrt{(4-10)^2+(-1-2)^2}=3\sqrt5[/tex]

[tex]CD=\sqrt{(12-(-4))^2+(8-0)^2}=8\sqrt5[/tex]

[tex]AP=\sqrt{(4-2)^2+(-1-3)^2}=2\sqrt5[/tex]

so the area is

[tex]\dfrac{(3\sqrt5+8\sqrt5)2\sqrt5}2=\boxed{55}[/tex]

Identify the domain of the function shown in the graph

Answers

Answer: A

Step-by-step explanation:

The domain of a function is the minimum and maximum value of independent variable (x).

The domain of the function according to the given graph will be the starting point of the line of best fit to the end point of the line.

Trace the starting point and the end point to the x - axis.

If you do so, the starting point is 2 and the end point is 10.

The domain is therefore, 2< = x <= 10. The correct answer is A

we know that [tex]\pi = 360 degrees[/tex][tex]\pi = 360 \ degrees[/tex]

we have to find value of [tex]5\pi /6[/tex]

for that we have to multiply 5/6 to [tex]\pi[/tex] and 360 degrees

So your answer is  d = -1/4 = -0.250

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    6*d-11/2-(2*d-13/2)=0

           13

Simplify   ——

           2

 (6d -  ——) -  (2d -  ——)  = 0

2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  2  as the denominator :

          2d     2d • 2

    2d =  ——  =  ——————

          1        2  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

2d • 2 - (13)     4d - 13

—————————————  =  ———————

      2              2  

        11     (4d - 13)

4.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  2  as the denominator :

          6d     6d • 2

    6d =  ——  =  ——————

5.1       Adding fractions which have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

(12d-11) - ((4d-13))     8d + 2

————————————————————  =  ——————

         2                 2  

6.1     Pull out like factors :

  8d + 2  =   2 • (4d + 1)

 4d + 1  = 0

 4d + 1  = 0

7.1      Solve  :    4d+1 = 0

Subtract  1  from both sides of the equation :

                     4d = -1

Divide both sides of the equation by 4:

                    d = -1/4 = -0.250

Ryan had $80. He spent $32 on a book. what percentage of his money did he spend on the book? What percentage of his money did he have left?

Answers

Answer:

40% spent. 60% left.

Step-by-step explanation:

To find the percentage spent, divide the two values, then multiply by 100.

$32 / $80 = 0.40    0.40 x 100 = 40% spent.

To find the percentage of money left, subtract the two values.

$80 -$32 = $48

Then, divide the two values and multiply by 100.

$48 / $80 = 0.60   0.60 x 100 = 60% left.

Kate and Jean paint a house together in 6 days. If they work alone, Kate takes 5 fewer days than Jean would take to do the same job. Which equation represents the time it takes Kate to paint the house by herself? A. X^2-7x-30=0 B. X^2-5x-6=0 C. 2x-1=0 D. X^2-5x/6=0

Answers

Answer: [tex]x^2-17x+30=0[/tex]

Step-by-step explanation:

Let x = Time taken (in days) by Jean to do the job.

Then, Time taken by Kate to do the job = x-5

Then, together they will take time (t) as

 [tex]\dfrac{1}{t}=\dfrac{1}{x}+\dfrac{1}{x-5}[/tex]

[tex]=\dfrac{x-5+x}{x(x-5)}=\dfrac{2x-5}{x(x-5)}[/tex].

[tex]\Rightarrow\ t=\dfrac{x(x-5)}{2x-5}[/tex]

Since it is given that Kate and Jean paint a house together in 6 days.

i.e.

[tex]6=\dfrac{x(x-5)}{2x-5}\\\\\Rightarrow 6(2x-5)=x^2-5x\\\\\Rightarrow\ 12x-30=x^2-5x\\\\\Rightarrow\ x^2-5x-12x+30=0\\\\\Rightarrow\ x^2-17x+30=0[/tex]

So, the equation represents the time it takes Kate to paint the house by herself is [tex]x^2-17x+30=0[/tex] .

What is expression?

Expression is combination of numbers, fraction, symbols , coefficients, indeterminants or determinants. It shows a relationship between variables. It is mostly not found in equal to form.

How to form algebraic expression?

We have been given p% of m and we have to form an expression of this.

To express this we have to just solve the percentage and because we donot have any number so will only write p/100 in place of p%.

p% of m=p/100*m

=pm/100

Suppose that the U.S. government decides to charge cola producers a tax. Before the tax, 50 billion cases of cola were sold every year at a price of $5 per case. After the tax, 44 billion cases of cola are sold every year; consumers pay $6 per case, and producers receive $2 per case (after paying the tax). The amount of the tax on a case of cola is $ per case. Of this amount, the burden that falls on consumers is $ per case, and the burden that falls on producers is $_________ per case, and the burden that falls on producers is $ _____ per case.The effect of the tax on the quantity sold would have been larger if the tax had been levied on consumers.a.
