Answer:

  D.  2%  

Step-by-step explanation:

The growth rate can be found by looking at the growth factor of the exponential function.

  f(x) = (initial value) × (growth factor)^x

The growth rate is related by ...

  growth factor = growth rate + 1

This means the growth rate of f(x) is 1.04 -1 = 0.04 = 4%.

__

We can write the function g(x) describing the table as ...

  g(x) = (value at x=x1) × ((value at x=x2)/(value at x=x1))^((x-x1)/(x2-x1))

So, this could be ...

  g(x) = 31.21 × (32.47/31.21)^((x-2)/2) = a·b^x

     where b = (32.47/31.21)^(1/2) ≈ 1.02 . . . . growth factor

This means the growth rate for g(x) is 1.02 -1 = 0.02 = 2%.

__

Then the difference between the growth rates of the two functions is ...

  4% - 2% = 2% . . . . . matches choice D

Answer:

(1, 3 )

Step-by-step explanation:

Substitute x = 1 into the equation

y = [tex]\frac{1}{2}[/tex] × [tex]6^{1}[/tex] = [tex]\frac{1}{2}[/tex] × 6 = 3

(1, 3 ) ← with output value y = 3

The required output value for the exponential function at x = 1 is y = 3.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

The function which is in format f(x) =   where, a is constant and x is variable,  the domain of this exponential function lies   (-∞, ∞).  

Here,
[tex]y = 1/2*6^x[/tex]
at x = 1
putting the value of the x in [tex]y = 1/2*6^x[/tex]
[tex]y = 1/2*6^1[/tex]
y = 6/2
y = 3

Thus, the required output value for the exponential function at x = 1 is y = 3.

Answer:

750 units.

Step-by-step explanation:

30 x 30 = 900 units (total space in the classroom)

2 x 3 = 6 units (how much space each desk takes up)

25 x 6 = 150 units (number of desks for each student)

900 - 150 = 750 units

Answer:

-7, 1

Step-by-step explanation:

The roots of an equation are the answers to the equation, where the graph of the equation intersects the x-axis. One can see that the points at which the graph intersect the x-axis are the following,

(-7, 0) and (1, 0), therefore the roots to the equation are the following;

Answer: 6.6 miles

Step-by-step explanation:

Since he finished 22% of his skiing in the morning, that means he still has 78% (100% - 22%) of his skiing left.

The remaining 78% is equivalent to 23.4 miles. We need to know the total miles of the skiing. This will be:

78% of x = 23.4

0.78 × x = 23.4

0.78x = 23.4

x = 23.4 / 0.78

x = 30 miles

Since the total skiing is 30 miles and he has 23.4 miles left, the miles covered in the morning will be:

= 30 - 23.4

= 6.6 miles

Answer:

question 1 , area= 42.02 sq meter, circumference=22.98 meter

question 2, area=481.609sq meter, lenght of BC=263.3472 meter

for convience i converted yards to meter.

Step-by-step explanation:

in first question to find area of circle by multiplying value of pi (3.14) and square of radius of circle and to find circumference just multiply 2 with value of pi(3.14) and radius of circle.

in the second question to find area of sector use formula 1/2 r^2 x72 and to find lenght of arc bc use formula length= radius x 72

Given:

Two triangles congruent by ASA.

To find:

The the measures of x, y, angle QPR and angle QRP.

Solution:

The triangles PQR and PSR are congruent by ASA. So,

[tex]\angle QPR\cong \angle SPR[/tex]

[tex]PR\cong PR[/tex]

[tex]\angle QRP\cong \angle SRP[/tex]

Now,

[tex]m\angle QPR=m\angle SPR[/tex]

[tex]2x+1=x+18[/tex]

[tex]2x-x=18-1[/tex]

[tex]x=17[/tex]

And,

[tex]\angle QRP= \angle SRP[/tex]

[tex]8y-4=4y+28[/tex]

[tex]8y-4y=4+28[/tex]

[tex]4y=32[/tex]

Divide both sides by 4.

[tex]y=8[/tex]

The measure of angle QPR is:

[tex]m\angle QPR=(2x+1)^\circ[/tex]

[tex]m\angle QPR=(2(17)+1)^\circ[/tex]

[tex]m\angle QPR=(35+1)^\circ[/tex]

[tex]m\angle QPR=36^\circ[/tex]

And,

[tex]m\angle QRP=(8y-4)^\circ[/tex]

[tex]m\angle QRP=(8(8)-4)^\circ[/tex]

[tex]m\angle QRP=(64-4)^\circ[/tex]

[tex]m\angle QRP=60^\circ[/tex]

Therefore, the required values are [tex]x=17, y=8, m\angle QPR=36^\circ ,m\angle QRP=60^\circ[/tex].
