A new fitness center opens with 120 members. Every month the fitness center increases the number of members by 40 members. How many members will the fitness center have after being open for 3 months?
Answer:
240 members
Step-by-step explanation:
Let y = total and x = no. of months
y = 40x + 120
= 40(3) + 120
= 120 + 120
= 240 members

There is a rope running from the top of a flagpole to a hook in the ground. The flagpole is 8 meters high, and the hook is 2 meters from its base. How long is the rope? If necessary, round to the nearest tenth.
ASAP Please!
Answer: 8.2m
Step-by-step explanation:
Let the hook that is 2m from the base represent a
Let the height of the flagpole represent b
The length of the rope (hypotenuse) is c
[tex]\begin{aligned}&a^{2}+b^{2}=c^{2} \\&2^{2}+8^{2}=c^{2} \\&4+64=c^{2} \\&\sqrt{68}=\sqrt{c}^{2}\end{aligned}\\c= 8.25m[/tex]

f(x) = (2x − 3)(x + 6)(5x + 6) has zeros at x = -6, x = -6/5 and x =3/2.
What is the sign of f on the interval - 6
Answer:
Step-by-step explanation:
f ( - 7 ) = [ 2 ( - 7 ) - 3]( - 7 + 6 )[ 5 ( - 7 ) + 6 ] = ( - 17 )( - 1 )( - 29 ) < 0 , Negative
f ( - 5 ) = [ 2 ( - 5 ) - 3]( - 5 + 6 )[ 5 ( - 5 ) + 6 ] = ( - 13 )( + 1 )( - 19 ) > 0 , Positive
f ( - 1 ) = [ 2 ( - 1 ) - 3]( - 1 + 6 )[ 5 ( - 1 ) + 6 ] = ( - 5 )( + 5 )( + 1 ) < 0 , Negative
The answer is (A) " f " is always POSITIVE

Nate has an account that pays 2. 76% simple interest per year and wants to accumulate $3,090 in interest from it over the next 15 years. How much money should Nate invest in this account to meet this goal? a. $1,279. 26 b. $4,369. 26 c. $4,373. 77 d. $7,463. 77.
We have given that,
interest rate = 2.76%
simple interest = 3,090
term = 15 years
What is the principle of simple interest?[tex]Simple Interest = Principal * interest rate * term[/tex]
[tex]3,090 = Principal * .0276 * 15\\3,090 = Principal * 0.414\\3,090 / 0.414 = Principal\\7,463.77 = Principal[/tex]

Since 12:00 a.m., a cold front has caused the temperature in a particular city to decrease at a constant rate. At 2:00 a.m., the temperature was 54 degrees Fahrenheit, and at 5:00 a.m., the temperature was 45 degrees Fahrenheit. Which of the following statements are correct? Select TWO that apply.
The temperature in a particular city to decrease at a constant rate of 3°F per hour.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
At 2:00 a.m., the temperature was 54 degrees Fahrenheit, and at 5:00 a.m., the temperature was 45 degrees Fahrenheit. Hence:
Rate of change = (45°F - 54°F) / (5 - 2) = -3

Tim made 10 baskets during a basketball game. Each basket was worth either 2 or 3 points. How many different numbers could represent the total points scored by Jordan? What's the answer?
The total point is an illustration of arrangements
There are 6 different numbers that could the total points scored by Tim
How to determine the number of total points?The different number (n) that can represent the total point is calculated as:
n = 2 points + 3 points + 1
Remove the units
n = 2 + 3 + 1
Evaluate the sum
n = 6
Hence, there are 6 different numbers that could the total points scored by Tim

Somebody help me please
Answer:
see explanation
Step-by-step explanation:
given
(2x + 5)(2x - 1) ← expand using FOIL
(a)
= 4x² - 2x + 10x - 5 ← collect like terms
= 4x² + 8x - 5
(b)
using the method of completing the square on
4x² + 8x - 5 ← factor out 4 from the 1st 2 terms
= 4(x² + 2x) - 5
to complete the square
add/ subtract ( half the coefficient of the x- term )² to x² + 2x
= 4(x² + 2(1)x + 1 - 1) - 5
= 4(x + 1)² - 4 - 5
= 4(x + 1)² - 9
Write a function rule for the table.
f(x) = 4 – x
f(x) = –4x
f(x) = x + 4
f(x) = x – 4
Answer:
f(x) = x – 4
checking for all the functions by replacing x as 3
f(x) = 4 – x
f(3) = 4 - 3
f(3) = 1
does not match
f(x) = –4x
f(3) = -4(3)
f(3) = -12
does not match
f(x) = x + 4
f(3) = 3 + 4
f(3) = 7
does not match
f(x) = x – 4
f(3) = 3 - 4
f(3) = -1
matches
Answer:
f(x) = x - 4
Step-by-step explanation:
The options are:
f(x) = 4 – x
f(x) = –4x
f(x) = x + 4
f(x) = x – 4
For f(x) = 4 – x, when x=3, f(x)=1 so it cannot be right.
For f(x) = –4x, when x=3, f(x)=-12 so it cannot be right either.
f(x) = x + 4, when x=3, f(x)=7 so it cannot be right.
The only choice left which is also the right answer is f(x) = x – 4

Find an equation for the perpendicular bisector of the line segment whose endpoints are (5, 5) and ( 7, 1).
Answer:
x -2y = 0
Step-by-step explanation:
A perpendicular bisector is a line perpendicular to a given line or segment that goes through the midpoint between given points. The perpendicular line will have a slope that is the opposite reciprocal of the slope of the segment between the given points.
__
The midpoint between A and B is ...
M = (A +B)/2
M = ((5, 5) +(7, 1))/2 = (12, 6)/2 = (6, 3)
The slope of the line between A and B is ...
m = (y2 -y1)/(x2 -x1)
m = (1 -5)/(7 -5) = -4/2 = -2
__
The opposite reciprocal of the slope of the given segment is ...
m' = -1/-2 = 1/2
The point-slope form of the equation of the perpendicular bisector can be written as ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
y -3 = 1/2(x -6) . . . . line with slope 1/2 through point (6, 3)
Multiplying by 2 gives ...
2y -6 = x -6
Subtracting (2y -6) gives the standard-form equation ...
x -2y = 0
