On the map at the right, the public swimming pool can be represented by the point (-6, 5) and Tim’s house can be represented by the point (1, 5). If each unit on the graph represents 0.5 miles, how many miles is Tim’s house from the pool
The distance between the swimming pool and Tim's house is 3.5 miles.
How to find the distance?
First, we need to find the distance between the two points, and then we multiply that by 0.5 miles.
The distance between the points (-6, 5) and (1, 5) is:
[tex]d = \sqrt{(-6 - 1)^2 + (5 - 5)^2} = 7[/tex]
Now, changing to miles, we get:
d = 7*0.5mi = 3.5mi
So the distance is 3.5 miles

A spherical balloon is inflated so that its volume is increasing at the rate of 2.5 ft3/min. How rapidly is the diameter of the balloon increasing when the diameter is 1.3 feet?
Answer:
.9417 ft/min
Step-by-step explanation:
Sphere volume = 4/3 pi r^3
dv/dr = 4/3 pi * 3 r ^2 = 4 pi r^2
dv/dr * dr/dt = dv/dt = 4 pi r^2 dr/dt
2.5 = 4 pi (1.3/2)^2 dr/dt (Diameter is 1.3 , radius is 1.3/2)
dr/dt = .4709 ft/min
THIS answer is how fast the RADIUS is changing
the DIAMETER is changeing TWICE this:
2 x .4709 ft/min = .9417 ft / min = diameter/dt

Which explicit function defines this arithmetic sequence?
-351, -343, -335, -327, -319
A.
f(n) = 8n − 351
B.
f(n) = -8n − 351
C.
f(n) = 8n − 359
D.
f(n) = -8n + 359
Answer:
C. f(n) = 8n − 359
Step-by-step explanation:
The given arithmetic sequence has first term -351, and common difference (-343 -(-351)) = 8. The common difference will be the multiplier of n in the explicit function.
__
You can identify the appropriate explicit function by finding the one that correctly describes the sequence. Evaluating each for n=1 is sufficient. (You will note that choices B and D have the wrong sign on the multiplier of n.)
A f(1) = 8 -351 = -343
B f(1) = -8 -351 = -359
C f(1) = 8 -359 = -351 . . . . correctly gives the first term
D f(1) = -8 +359 = 351
The sequence is defined by the explicit function ...
f(n) = 8n -359
Answer:A:f(n)=8n-359

Sam is thinking of retiring from his job after many years of faithful service. during the last 35 years at his job, his annual salary averages to $37,991. every month, his bills total $1,755. how much money would sam need each month to supplement his monthly social security benefit (assuming his annual benefit is 42% of his salary average) and still be able to pay his bills? a. at least $81.23 b. at least $425.32 c. at least $1,410.92 d. at least $3,019.67
Using proportions, the amount of money that Sam would need each month to pay his bills is of:
b. at least $425.32.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, his annual social security benefit is of 42% of $37,991, hence:
A = 0.42 x 37991 = $15,956.22.
Hence the monthly amount is given by:
M = 15956.22/12 = $1,329.68
He needs $1,755 monthly, hence the amount he needs is of at least:
An = 1755 - 1329.68 = $425.32.
Which means that option b is correct.

Using the corresponding angles theorem, the value of x is 150°
Calculating the measures of anglesFrom the question, we are to determine the value of the angle marked x°
From the diagram,
The angle that supplements the angle marked 30° is corresponding to angle x
Since corresponding angles are equal
Then, we can write that
∴ x = 180° - 30°
x = 150°
Hence, the value of x is 150°
