Function c is defined by the equation c(n) = 50 + 4n. It gives the monthly cost, in dollars, of visiting a gym as a function of the number of visits, n.

Answers

Answer:

78 dollars

Step-by-step explanation:

Function c is defined by the equation c(n) = 50 + 4n. It gives the monthly cost, in dollars, of visiting a gym as a function of the number of visits, n. Find the value of c(7).

Given:

c(n) = 50 + 4n

Where,

c = monthly cost of visiting a gym

n = number of visits

Find the value of c(7)

That is, when n = 7

c(n) = 50 + 4n

c(7) = 50 + 4(7)

= 50 + 28

= 78

c(7) = 78 dollars

(x+4),(x+12),(x-1) and (x+5) are in proportion .find the value of x

Answers

Answer:

x = 16

Step-by-step explanation:

(x +4) : (x +12) :: (x-1)(x +5)

As they are in proportion,

Product of means = Product of extremes

(x + 4)* (x +5) = (x + 12)(x - 1) {Use FOIL method}

x*x +x*5 +4*x + 4*5 = x *x + x*(-1) +12*x + 12*(-1)

x² + 5x + 4x + 20 = x² - x +12x - 12 {Now combine like terms}

x² + 9x + 20 = x² + 11x -12

x² + 9x +20 - x² - 11x = -12

x² - x² + 9x - 11x = -12 - 20

0 - 2x = - 32

-2x = -32 {Divide both sides by -2}

x = -32/-2

x = 16

An election was held between two persons to select a representative to a certain
institution. All the voters who were registered cast their votes. The winner
received 7/12 of the votes and
won by a majority of 120 votes.

(i) What fraction of the total votes did the person who lost receive?
(ii) How many registered voters were there?
(iii) Find the number of votes the winner received.

Answers

9514 1404 393

Answer:

(i) 5/12

(ii) 720

(iii) 420

Step-by-step explanation:

(i) The fraction representing all votes is 12/12. If 7/12 were received by the winner, then the loser received 12/12 -7/12 = 5/12 of the total votes.

The person who lost received 5/12 of the total votes.

(ii) The winner won by 7/12 -5/12 = 2/12 = 1/6 of all votes. So, the total number of votes is ...

120 votes = 1/6(total votes)

total votes = 6×120 votes = 720 votes

There were 720 registered voters.

(iii) The winner received ...

(7/12)(720 votes) = 420 votes . . . received by the winner

What would x equal( rounded to the nearest tenth)

Answers

You are given the opposite: 16 km
You need to find x (adjacent)
The angle measure: 28 degrees
With opposite and adjacent, use tangent
Tan(28) = 0.5317094317
Tan(28) = 16/x
x = 16/0.5317094317
x = 30.0916
Round to nearest tenth
Solution: x = 30.1 km

.After making his first deposit, Paul has $758 in his checking account. The next month,
the balance is $836. The balance after the third month is $914.

Using liner sequences & function

Answers

78 is the answer
If you substract 914-836 that equals 78
And if you substract 836-758=78 too

Answer:

Step-by-step explanation:

This is the way I understand the question. I hope it makes sense.

∑ (P + 78n) P = the initial depost which is 758

n = 0

so when n = 0 the sum equals P or 758 because 78(0) = 0

so when n = 1 the sum equals P+78(1) = 758 + 78 = 836

so when n = 2 the sum equals P+78(2) = 758 + 156 = 914

Can someone help me with this. Will Mark brainliest.

Answers

Answer:

The lines are perpendicular.

Step-by-step explanation:

If the lines are parallel, then the slopes are equal

If the lines are perpendicular, then the slopes are negative reciprocals

If neither of the above occur, then the lines are neither parallel or perpendicular.

y = 2x + 3 is in slope-intercept form, so the slope = 2

2y + x = 6

Solve for y: 2y = -x + 6

y = -1/2(x) + 3 so the slope = -1/2

2 and -1/2 are negative reciprocals, so the lines are perpendicular.

Note: Negative reciprocals have a product of -1. 2(-1/2) = -1

Christopher is solving a system of equations that has one solution and can be seen in Option C.

What is a system of equations?

A system of equations is two or more equations that can be solved together to get a unique solution. In this situation, the power of the equation must be in one degree.

A quadratic equation is the second-order degree algebraic expression in a variable.

s(x) = 2x42 -5 and t(x) = -x +31+2

However, if their power is not in one degree, the quadratic equation produces two solutions.

From the given options, we can see that only option c is not a quadratic equation, Hence, it is the right answer.

Answers

Answer:

tanx°=p/b

tanx°=45/30

x°=tan-¹(45/30)=56.30=56

Answer:

0.03

Step-by-step explanation:

In given triangle,

perpendicular(p)=45

base(b)=30

x=?

We know,

tanx = p/b

or, tanx = 45/30

or, tanx = 3/2

or, x = tan-1(9/7)

or, x = 56.3099324740202 i.e. 56 approximately

WILL GIVE BRAINLIEST FOR ANSWER Find the area of the shaded polygons.

Answers

Answer:

7.74 cm2

Step-by-step explanation:

We need to find the area of both the square and the circle and then subtract the two. Inscribed means draw within a figure so as to touch in as many places as possible. So the circle is drawn inside the square. The opposite is circumscribed, meaning drawn outside.

Asquare = s2 = 36 cm2 so the side is 6 cm

6 cm is also the diameter of the circle and thus the radius is 3 cm

A circle = πr2 = 3.14 * 32 = 28.28 cm2

The resulting difference is 7.74 cm2
