What was the approximate number of mobile cellular subscriptions per 100 people in Zimbabwe in 2003?
The display gives the result of performing an exponential regression on a data set where the inputs are years since 2000 and the outputs are the corresponding mobile cellular subscriptions per 100 on Zimbabwe.
ExpReg
y=a*b^x
a=1.067905095
b=1.501755837
r^2=.9525580427
r= .9759908005
A. 2
B. 4
C. 6
D. 8
Answer:
B. 4
Step-by-step explanation:
Given exponential model that shows the number of mobile cellular subscriptions per 100 people in Zimbabwe since 2000,
[tex]y=a b^x[/tex]
Where,
a=1.067905095
b=1.501755837,
[tex]\implies y=1.067905095(1.501755837)^x[/tex]
Since, the number of years from 2000 to 2003 = 3,
Thus, for finding the number of subscriptions in 2003,
x = 3,
Hence, the number of mobile cellular subscriptions per 100 people in Zimbabwe in 2003 is
[tex]y=1.067905095(1.501755837)^3=3.61685122094\approx 4[/tex]
Option 'B' is correct.

Write a compound inequality that represents the situation.
all real numbers at least –6 and at most 3
Answer:
[tex]\[-6 \leqslant x \leqslant 3\][/tex]
Step-by-step explanation:
The requirement is to represent a compound inequality with all real numbers at least –6 and at most 3.
This can be broken into two parts:
a) All real numbers at least -6
[tex]\[x\geqslant -6\][/tex]
b) All real numbers at most 3
[tex]\[x \leqslant 3\][/tex]
Combining the two inequalities to generate the compound inequality:
[tex]\[-6 \leqslant x \leqslant 3\][/tex]

What is the point slope form of the line with slope −1/4 that passes through the point (−2, 9) ?
y+9=−14(x−2)
y−2=−14(x+9)
y+2=−14(x−9)
y−9=−14(x+2)
Answer:
Step-by-step explanation:
Point slope form of the equation with point (a,b) and slope m is given by this equation
y-b=m(x-a)
Here we are given that the slope is -1/4 so m= -1/4
and the point is (-2,9) so a =-2 and b =9
Hence plugging the values in the equation we get
y-9 = -1/4 (x-(-2))
y -9 =-1/4 (x+2)
A diver descends to a location of −5014 meters relative to the surface of the water. He then descends another 1012 meters.
What is the diver’s final location relative to the surface of the water?
Enter your answer as a simplified mixed number in the box.
Answer: Using operations with fractions, the diver's final location is:
- 60 3/4 meters relative to the surface of the water (60 3/4 meters below the surface of the water).
Solution:
Initial location: -50 1/4 meters
He descends another 10 1/2 meters: -10 1/2 meters
Final location = Initial location - 10 1/2 meters
Final location = - 50 1/4 meters - 10 1/2 meters
Final location = - (50+10) (1/4+1/2) meters
Final location = - 60 [(1)(1)+2(1)]/4 meters
Final location = - 60 (1+2)/4 meters
Final location = - 60 3/4 meters

If f(x) = 5x, what is f–1(x)?
A. f–1(x) = –5x
B. f-1(x)=-1/5x
C. f-1(x)=1/5x
D. f–1(x) = 5x
Interchange to get:
x=5y-7
Solve for y to get:
y=(1/5)x+(7/5)
so I think it might be c
Answer:
The answer is C.
Step-by-step explanation:
Step 1: Replace f(x) with y.
f(x)=5x >>>>> y=5x
Step 2: Switch x and y.
y=5x >>>>> x=5y
Step 3: Solve for y
x=5y >>>> y= x/5
Then you have to do the inverse of dividing by 5. Which is multipilying by 1/5. This leaves you with,
y= 1/5x
Step 4: Write in standard inverse notation (Replace y with f^-1(x))
f^-1(x)=1/5x
Note: These steps work with ANY problem where you have to find the inverse function. I hope this helps :)
What is the area of a rectangle with vertices at (−6, 3) , (−3, 6) , (1, 2) , and (−2, −1) ? Enter your answer in the box. Do not round any side lengths.
The area of the rectangle is 18 square units if the vertices at (−6, 3) , (−3, 6) , (1, 2) , and (−2, −1).
What is the area of the rectangle?It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
It is defined as the two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.
It is given that:
A rectangle with vertices at a (−6, 3) , b (−3, 6) , c(1, 2) , and d(−2, −1)"
As we know,
The distance formula can be given as:
[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
ab = √(x₁-x₂)²+(y₁-y₂)²
=√(-6+3)²+(3-6)²
= √18
cd =√(1+2)²+(2+1)²
= √18
Area= lxw
A=√18x√18
a=18
Thus, the area of the rectangle is 18 square units if the vertices at (−6, 3) , (−3, 6) , (1, 2) , and (−2, −1).

What is the surface area of a sphere with a diameter of 16 cm?
A. 1,024n cm²
B. 32n cm²
C. 256n cm²
D. 128n cm²
Answer:
The correct option is C. The surface area of a sphere is 256π cm².
Step-by-step explanation:
Given information: The diameter of the circle is 16 cm.
[tex]r=\frac{d}{2}=\frac{16}{2}=8[/tex]
Radius of the circle is 8 cm.
Surface area of a sphere is
[tex]A=4\pi r^2[/tex]
Where, r is radius.
[tex]A=4\pi (8)^2[/tex]
[tex]A=4\pi (64)[/tex]
[tex]A=256\pi[/tex]
The surface area of a sphere is 256π cm². Therefore the correct option is C.

A) x + 9 < 5
B) x - 5 < 9
C) x + 5 < 9
D) x - 9 < 5
Answer:
there is an open dot on 4.....an open dot means there is no equal sign in the problem....and it is shaded to the left...means it is less then. So ur looking for an inequality with the answer being x < 4.
x + 5 < 9 <== its gonna be this one
