Answer:

  C.  f(x) > g(x) for x > 2

Step-by-step explanation:

Using a graph is probably the easiest way to compare an exponential function with a polynomial function. There are no algebraic methods for finding points of intersection. ("Trial and error," or "table of values" will work.)

A graph of these two functions shows f(x) > g(x) except on the interval [1, 2]. That is, f(x) > g(x) for x > 2.

The analysis shows there is a correlation between income and phone usage. There may or may not be causation. Further studies would have to be done to determine this.

Correlation is a statistical measure used to measure the relationship that exists between two variables. It is used to measure the direction of change in one variable when there is a change in another variable.

Causation is when a change in one variable leads to another change in the other variable.

Answer: 70%

Step-by-step explanation:

Not sure if this is correct but according to the red numbers there is a total of 20 classes. Looking at how many of these classes have 21 or more students we can see that the last three bars contain classes of 21 or more students. The last three bars contain a total of 14 of the 20 classes.

14/20 = 0.7 = 70%

meaning 70% of the classes contain at least 21 students.

Answer:

coplete the table by filling in the estimated and actual elapsed time.

Answer:

base(b)=10 and height(h)=6

Step-by-step explanation:

From the question,

base(b)=x feet

height(h)=(x-4) feet

Area(A)=30 square feet

Now,

We know,

Area of triangle(A)=1/2*b*h

or, 30=1/2*x*(x - 4)

or, 30=1/2*x^2 -4x

or, 30*2=x^2 -4x

or, 60=x^2 -4x

or, 0 = x^2 -4x -60

or, 0 = x^2 +6x - 10x -60

or, 0 = x(x + 6) -10(x + 6)

or, 0 = (x+6) (x-10)

Either,

x+6=0. or, x-10=0

or,x= -6. or, x= 10

Since, the base of the triangle can not be negative number then, x≠ -6feet but x=10feet

Lastly,

Height(h)=X - 4

=10 - 4

=6 feet

Answer: [tex]\frac{23}{7}[/tex]

Step-by-step explanation:

    An improper fraction is a fraction with the wholes / ones in the numerator.

3 [tex]\frac{2}{7}[/tex]

3 * 7 = 21

21 + 2 = 23

[tex]\frac{23}{7}[/tex]

Answer:

23/7

Step-by-step explanation:

You multiply 7 times 3 which equals 21 then add 2 and get 23 you leave yor denominator the same.

So you multiply your denominator by your wole number then add the whole number (21) by your numerator (2) and leave your denominator (7) as it is.

Answer:

The answer is 94.25 sq.in

Step-by-step explanation:

Given rectangle- 7 1/4 in by 13

to fin area for one of the triangles

For triangle, base = 13 in, height = 7 1/4 in, = 29/4 in

Area- 1/3 x base x height = 1/2 x 13 x 29/4 in. 2

= 37/4 in. 2

= 94.25 sq. in

Answer:

y = $38.97

y = 6.495(5) + 6.495

Step-by-step explanation:

So for this problem, since it states the cost and length of the subscription are related, you can use the two subscription costs as data (or coordinate) points.

1 year = 12.99, 3 year = 25.98; so (1,12.99), (3, 25.98) use these points to calculate the average rate of change (or the slope (m)).

(y - y1)/(x - x1) = m so, (25.98-12.99)/(3 - 1) = 6.495, this is the slope, m

y = 6.495(x) + b now just pick one of the points and put in the x and y values to solve for b

12.99 = 6.495(1) + b solve for b and you discover it also = 6.495 = b

so y = 6.495(x) + 6.495 is the equation of the line, to answer their question, just pop in x=5 for the 5 years subscription cost

y = 6.495(5) + 6.495

y = $38.97

- 2/3 is the correct answer

Step-by-step explanation:

The rate of change of function K is -2/3. Therefore, option B is the correct answer.

The rate of change, or the slope, is calculated as Δy/Δx , or (y2−y1)/(x2−x1). The slope-intercept equation of a line is y=mx+b , where m is the slope and b is the initial value.

Given that, linear function K passes through points (-3,7) and (3,3).

Now, the rate of change

= (3-7)/(3+3)

= -4/6

= -2/3

Therefore, option B is the correct answer.

Answer:

  a) 160 meters short

  b) d = 200x +80y

  c) (run, walk) = (2, 15), (4, 10), (6, 5)

  d) see attached

Step-by-step explanation:

You're being asked to write an equation describing the gym class requirement, and to find several values of the variables that satisfy the equation.

It is convenient to write the equation first (part b).

__

At 200 meters per minute, in x minutes, Eric will run 200x meters. At 80 meters per minute, Eric will walk 80y meters in y minutes. His total distance covered will be ...

  d = 200x +80y

__

In the given times, Eric's distance covered is ...

  d = 200(4) +80(8) = 800 +640 = 1440 . . . meters

Eric is 160 meters short of the 1600-meter goal.

__

It is convenient to simplify the equation to one that lets us find one value in terms of the other.

  200x +80y = 1600

  5x +2y = 40 . . . . . . . . divide by 40

This will have integer solutions for even values of x in the range 0 to 8.

  y = (40 -5x)/2

For x={2, 4, 6}, we have ...

  y = (40 -5{2, 4, 6})/2 = {30, 20, 10}/2 = {15, 10, 5}

Eric can cover 1600 meters in (run, walk) times of ...

  (run, walk) = (2, 15), (4, 10), (6, 5)

__

Step-by-step explanation:

The time taken by projectile to hit the ground is 20 second.

The polynomial equations of degree 2 for a single variable of type f(x) = ax2 + bx + c = 0, where a, b, c, ∈ R, and a ≠ zero, are known as quadratic equations. The leading coefficient is referred to as "a," and the absolute term of the quadratic equation is referred to as "c." The roots of the quadratic equation (α, β). are the values of x that satisfy the equation.

Given initial velocity of a projectile = 98 m/s

equation h = -4.9t² + 98t

where t = time and h = height of projectile,

time taken by projectile to hit the ground,

where h = 0

equation will be

-4.9t² + 98t = 0

4.9t² = 98t

4.9t = 98

t = 98/4.9

t = 20 second

Hence time taken is 20 second.
