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  

y = 4x + 30

Answer:

39 ft^2

Step-by-step explanation:

To find surface area you add up the all the areas of the shapes.

Triangle:

5x3=15

15/2= 7.5

Since there are 4 triangles its 7.5x4 which is 30.

Square:

3x3=9

7.5+7.5+7.5+7.5+9 or 30+9= 39

39 ft squared.

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

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.

Answer:

5

Step-by-step explanation:

Container volume = 2 1/2 liters

Bottle volume = 1/2 liters

No. of bottles = Container vol. / Bottle vol.

= 2 1/2 / 1/2

= 5/2 / 1/2

= 5

2.5 divided by 1/2=5

5 lemonade bottles

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)

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

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.

I hope this helps! Feel free to correct me if I am wrong.

Answer:

The major axis of the ellipse has length = the larger of 2a or 2b and the minor axis has length = the smaller. By the way: if a=b , then the "ellipse" is a circle.

The quotient of the start fraction 7 superscript 7 negative 6 over 7 squared end fractions is,

[tex]\dfrac{1}{7^8}[/tex]

Quotient is the resultant number which is obtained by dividing a number with another. Let a number a is divided by number b. Then the quotient of these two number will be,

[tex]q=\dfrac{a}{b}[/tex]

Here, (a, b) are the real numbers.

The number given in the problem is,

[tex]\dfrac{7^{-6}}{7^2}[/tex]

Let the quotient of these number is n. Therefore,

[tex]n=\dfrac{7^{-6}}{7^2}\\[/tex]

Now if the power of numerator is negative, then it can be written in denominator with positive power of the same number. Therefore, the above equation written as,

[tex]n=\dfrac{1}{7^2\times7^{6}}\\n=\dfrac{1}{7^{2+6}}\\n=\dfrac{1}{7^8}[/tex]

Hence, the quotient of the start fraction 7 superscript 7 negative 6 over 7 squared end fractions is,

[tex]\dfrac{1}{7^8}[/tex]

Answer:

[tex]y=11*3^x[/tex]

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]

[tex]\sf b^2= 9[/tex]

[tex]\sf b = 3[/tex]

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

ANSWER:

2.1

EXPLANATION:

angle = 38

opposite side = 1.3

hypotenuse = X

Based on this we must use sine (opposite / hypotenuse)

sin (38⁰) = 1.3 / x

x = 1.3 / sin (38⁰) [use calculator]

x = 2.1

The area of the tile is 12 square inches.

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.

                                                                         ×--×-×-----×-----×

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.
