In order to join a dancing club there is a $30 startup fee and a $4 monthly fee. Write an equation in slope intercept form that models this situation.

Answers

Answer:

y = 4x + 30

Step-by-step explanation:

The startup fee is $30 and must be paid before you begin.  This means that 30 in the y-intercept.  You pay $30 at 0 months.  Then you have to pay $4 every month after that.  This means that 4 is the slope.  So, after x months, the total amount you have paid, y, is

A dog is leashed to the corner of a house. How much running area does the dog have? Round your answer to the nearest square foot, if necessary.

Answers

Answer:

300pi square feet

Step-by-step explanation:

the dog can move inside of the 3/4 of a circle

the area of a circle is the radius squared times pi

20*20*pi=400pi

Since the house takes up 1/4 of the circle the dog is left with 3/4

400pi*3/4=300pi

2/4 + 3/9 in Modeling Fractions?

Answers

Answer: 13/12

Step-by-step explanation:

Reduce the fraction 3/9 to the lowest terms by extracting and canceling out 3.

The least common multiple of 4 and 3 is 12. Convert 3/4 and 1/3 to fractions with denominator 12.

Since 9/12 and 4/12 have the same denominator, add them by adding their numerators.

Add 9 and 4 to get 13.

Element X is a radioactive isotope such that every 22 years, its mass decreases by half. Given that the initial mass of a sample of Element X is 1200 grams, how long would it be until the mass of the sample reached 800 grams, to the nearest tenth of a year?

Answers

Step-by-step explanation:

s1 = 1200 g

s2 = 1200×2^(-1/22)

s3 = 1200×2^(-2/22)

...

s23 (22 years later) = 1200×2^-22/22 ≈ 1200×2^-1 = 1200/2

sn = 1200×2^(-(n-1)/22)

what is the n, so that the result is 800 g ?

800 = 1200×2^(-(n-1)/22)

800/1200 = 2^(-(n-1)/22)

2/3 = 2^(-(n-1)/22)

log2(2/3) = -(n-1)/22

22×log2(2/3) = -(n - 1) = -n + 1

n = -22×log2(2/3) + 1 = 13.86917502...

since we stared counting with n=1 for the starting quantity, the number of years is truly 1 less than n (s2 is after 1 year, s3 after 2 years ...).

so, we know for n = 13.86917502..., that in fact

12.86917502... ≈ 12.9 years have passed until the mass of the sample reached 800g.

Slope of (7, -2) and (2, -6)

Answers

Answer:

[tex]\boxed{\sf{m=\frac{4}{5}}}[/tex]

Step-by-step explanation:

In order to solve this problem, we will use the slope.

Slope:

[tex]\sf\dfrac{Y_2-Y_1}{x_2-x_1}=\dfrac{rise}{run}[/tex]

y2=(-6)

y1=(-2)

x2=2

x1=7

Solve the problem by rewriting it down.

[tex]\sf{\dfrac{(-6)-(-2)}{2-7} }=\dfrac{(-6)+2}{2-7}=\boxed{\dfrac{4}{5} }[/tex]

m=4/5

Therefore, the slope is 4/5.

if 8^{y}=18^{y+2} what is the value of y?

Answers

Answer:

-8

Step-by-step explanation:

both 8^-8 and 16^-8+2 equal 5.9605

[tex][Hello,BrainlyUser][/tex]

Answer:

y = -8

Step-by-step explanation:

Create equivalent expressions in the equation that all have equal bases.

[tex]2^3^y=2^4^(^y^+^2^)[/tex]

Since the bases are the same, then two expressions are only equal if the exponents are also equal.

[tex]3y=4(y+2)[/tex]

Simplify

[tex]4(y+2).[/tex]

Apply the distributive property.

[tex]3y=4y+4*2[/tex]

Multiply 4 by 2

[tex]3y=4y+8[/tex]

Subtract 4y from both sides of the equation.

[tex]3y-4y=8[/tex]

Subtract 4y from 3y.

[tex]-y=8[/tex]

Multiply each term in −y=8 by −1

[tex]y=-8[/tex]

Hence, Answer is y = -8

Here is the graph showing this function.

Answer:

[tex]\sf y = 11(3)^x[/tex]

given points: ( 0, 11) , (2,99)

solve for 1st

[tex]\sf y = ab^x[/tex]

[tex]\sf 11 = ab^0[/tex]

since we know [tex]\sf b^0 = 1[/tex]

[tex]\sf 11 =a[/tex]

solve for 2nd

[tex]\sf y = ab^x[/tex]

[tex]\sf 99 = ab^2[/tex]

[tex]\sf \dfrac{99}{b^2} = a[/tex]

solve simultaneously:

[tex]\sf 11 = \sf \dfrac{99}{b^2}[/tex]

[tex]\sf 11 b^2= \sf 99}[/tex]

The area of the tile is 12 square inches.

How to get the area of a rectangle?

For a rectangle of length L and width W, the area is given by:

A = L*W

In this case, we can see that the width is 2 inches and the length is 6 inches, then the area of this rectangle will be:

A = 6in*2in = 12 in^2

So we can conclude that the area of the tile is 12 square inches.

Help solve this math problem thing pleasereeee

Answers

Step-by-step explanation:

We have the equation y = 2x - 5

To complete the table of values substitute each of the x values into the equation

When x = 0

y = 2(0) - 5 which means y =(2 × 0) - 5 = -5

The coordinates you plot are (0,-5)

When x = 1

y = 2(1) - 5 which means y = (2 × 1) - 5 = -3

The coordinates you plot are (1,-3)

When x = 2

y = 2(2) - 5 which means y = (2 × 2) - 5 = -1

The coordinates you plot are (2,-1)

When x = 3

y = 2(3) - 5 which means y = (2 × 3) - 5 = 1

The coordinates you plot are (3,1)

When x = 4

y = 2(4) - 5 which means y = (2 × 4) - 5 = 3

The coordinates you plot are (4,3)

When x = 5

y = 2(5) - 5 which means y = (2 × 5) - 5 = 5

The coordinates you plot are (5,5)
