The population of a town is growing exponentially and can be modeled by the
equation f(t) = 42. e(0.015). The population is measured in thousands, and time is
measured in years 1950.
C. According to this model approximately what is the population in 1960?
The population of the town in 1960 is 48.80 thousands
How to determine the population in 1950?The equation of the model is given as:
f(t) = 42e^(0.015t)
1960 is 10 years after 1950.
This means that:
t = 10
Substitute t = 10 in f(t) = 42e^(0.015t)
f(10) = 42e^(0.015 * 10)
Evaluate
f(10) = 48.80
Hence, the population of the town in 1960 is 48.80 thousands

how many 4 digit numbers n have the property that the 3 digit number obtained by removing the leftmost digit is one ninth of n
Answer:
7
Step-by-step explanation:
We want to find the number 4-digit of positive integers n such that removing the thousands digit divides the number by 9.
__
Let the thousands digit be 'd'. Then we want to find the integer solutions to ...
n -1000d = n/9
n -n/9 = 1000d . . . . . . add 1000d -n/9
8n = 9000d . . . . . . . . multiply by 9
n = 1125d . . . . . . . . . divide by 8
The values of d that will give a suitable 4-digit value of n are 1 through 7.
When d=8, n is 9000. Removing the 9 gives 0, not 1000.
When d=9, n is 10125, not a 4-digit number.
There are 7 4-digit numbers such that removing the thousands digit gives 1/9 of the number.

What is the degree measure of ∠COA?
The degree measure of angle COA = 128 degree.
What is Angle Sum Property?It is defined by the property that the sum of the interior angles of a triangle is equal to 180 degrees.
To determine the value of angle COA ,
we have to draw a line connecting CA ,
as OC and OA are the radius of the circle and therefore the sides of the triangle formed will be equal and also the angle made by them ,
angle OAC = angle OCA
Therefore angle DCA = angle DAC
By angle sum property
2x + 52 = 180
2x = 128
x = 64 degree
angle DCO = 90 degree
Therefore angle ACO = 90-64 = 26 degree
Similarly, angle CAO = 26 degree
By angle sum property
26+26+x = 180
52+x = 180
x = 128 degree
The degree measure of angle COA = 128 degree.

Solvex - 5+ 7 = 15.

-13 and x = 3
C. x = -13 and x = -3
OD. x = 13 and x = -13
OB. x =
Answer:
A. X= 13 and X= -3
Step-by-step explanation:
subtract 7 from both sides, simplify, break down the problems into 2 equations, solve equations, and boom once solve both equations you get 2 solutions.
The solutions to the equation are x = 13 and x = -3.
Therefore, the correct option is A.
Given is an expression |x-5| + 7 = 15, we need to solve for x,
To solve the equation |x - 5| + 7 = 15 for x, we'll need to isolate the absolute value expression and then solve for x.
Here's the step-by-step process:
Step 1: Subtract 7 from both sides of the equation:
|x - 5| = 15 - 7
|x - 5| = 8
Step 2: Break the equation into two cases, one with the positive value inside the absolute value and one with the negative value inside the absolute value.
Case 1: x - 5 is positive:
For this case, the equation |x - 5| = 8 becomes:
x - 5 = 8
Now, solve for x:
x = 8 + 5
x = 13
Case 2: x - 5 is negative:
For this case, the equation |x - 5| = 8 becomes:
-(x - 5) = 8
Simplify and solve for x:
-x + 5 = 8
-x = 8 - 5
-x = 3
Multiply both sides by -1 to isolate x:
x = -3
So, the solutions to the equation are x = 13 and x = -3.

The length of the segment HI in the figure is 32.9
How to determine the length HI?To do this, we make use of the following secant-tangent equation:
HI² = KI * JI
From the figure, we have:
KI = 21 + 24 = 45
JI = 24
So, we have:
HI² = 45 * 24
Evaluate the product
HI² = 1080
Take the square root of both sides
HI = 32.9

given that x = 7.4 m and θ = 32°, work out bc rounded to 3 sf.
(not drawn to scale)
Answer:
BC ≈ 11.8 m
Step-by-step explanation:
using the tangent ratio in the right triangle
tanΘ = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{x}{BC}[/tex] , that is
tan32° = [tex]\frac{7.4}{BC}[/tex] ( multiply both sides by BC )
BC × tan32° = 7.4 ( divide both sides by tan32° )
BC = [tex]\frac{7.4}{tan32}[/tex] ≈ 11.8 m ( to 3 sf )
Yan is somewhere between his home and the stadium. To get to the stadium he can walk directly to the stadium, or else he can walk home and then ride his bicycle to the stadium. He rides 7 times as fast as he walks, and both choices require the same amount of time. What is the ratio of Yan's distance from his home to his distance from the stadium
Answer:
3/4
Step-by-step explanation:
The relationship between time, speed, and distance can be used together with the travel time relations to find the desired ratio.
__
setupLet H represent the distance from Yan's location to home. Let S represent the distance to the stadium, and let w represent Yan's walking speed.
The time required for Yan to walk home is ...
time = distance/speed = H/w
The time required for Yan to walk to the stadium is ...
time = S/w
The time required for Yan to ride his bike from home to the stadium is ...
time = (H +S)/(7w) . . . . . his riding speed is 7 times his walking speed.
In order for the travel times to be equal, we must have ...
time to walk home + time to bike to stadium = time to walk to stadium
H/w + (H +S)/(7w) = S/w
__
solutionMultiplying by 7w gives ...
7H +(H +S) = 7S
8H = 6S . . . . . . . . . subtract S
H/S = 6/8 = 3/4 . . . . divide by 8S
The ratio of Yan's distance from home to his distance from the stadium is 3/4.
_____
Additional comment
Another way to think about this is ...
The stadium is farther away than home by a distance that Yan can walk in the same time he can bike the entire distance from home to the stadium. That is, the difference in distances must be 1/7 of the total distance. Now, we have a "sum and difference" problem: S +H = 7, S -H = 1. The solution is S = (7+1)/2 = 4, H = (7-1)/2 = 3. H/S = 3/4.
Marcia needs a packing box with a volume of at least 180 cubic inches.
Part A
Is the box the correct size? Explain.
Question 2
Part B
Shipping costs $0.15 per cubic inch. How much will Marcia pay to ship the box?
Answer:
Part A: Yes
Part B: $30
Step-by-step explanation:
Some information is missing, but I did see a similar problem that shows a box shaped like a rectangular prism with length 5 in., width 4 in., and height 10 in.
Part A.
volume = length × width × height
volume = 5 in. × 4 in. × 10 in.
volume = 200 in.³
Since the volume has to be at least 180 in.³, then a volume of 200 in.³ will be ok since 200 is greater than 180.
Answer: Yes
Part B.
$0.15/in.³ × 200 in.³ = $30
