(a) entry fee cost

(b) the number of ride tickets James can buy (after he pays the entry fee)

(c) an equation for total cost y for purchase of x tickets

(a) We know the total cost is the cost of entry fee and ride tickets. For Jennifer, this is ...

... 30.75 = (entry fee) + 15×1.25

... 30.75 -18.75 = (entry fee)

entry fee = 12.00 . . . dollars

(b) If James spends his entire budget on entry fee and x rides, the number of ride tickets he can buy is given by ...

... 22 = 12 + 1.25x

... 10 = 1.25x

... 10/1.25 = x = 8

James can buy 8 ride tickets.

(c) The equation for total cost that we have been using is ...

... total cost = entry fee + (cost per ticket)×(number of tickets)

... y = 12 + 1.25x

(a)

the equation of a quadratic in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

here the vertex = (6, - 2 ) and a = 1

y = (x - 6 )² - 2 ← in vertex form

(b)

to find the zeros let y = 0

(x - 6 )² - 2 = 0 ( add 2 to both sides )

(x - 6 )² = 2 ( take the square root of both sides )

x - 6 = ±√2 ← ( note plus or minus )

add 6 to both sides

x = 6 ±√2 ← zeros

(c)

to obtain standard form expand the vertex form of the equation

y = x² - 12x + 36 - 2

y = x² - 12x + 34 ← in standard form

Answer:

(x-4)² + (y+3)² = 9

Step-by-step explanation:

The equation of a circle of radius r centered at (h, k) is ...

... (x-h)² + (y-k)² = r²

Subsituting your given values gives ...

... (x -4)² +(y -(-3))² = 3²

... (x -4)² +(y +3)² = 9

I'm assuming what you mean is what can you divide 3456 by to get a natural number.

First of all every number is divisible by 1.  

Every even number is divisible by 2, so since 3456 is an even number, it can be divided by 2.  That would equal 1728.

2456 can also be divided by 3, to get 1782.  

You can also divide it by 4, to get 865.

Divided by 6, it's 576.

Divided by 8, it's 432.

And lastly, 3456 divided by 9 is 384.

So, there isn't just one single-digit number you can divide 3456 by to get a natural number.  You can divide it by 1,2,3,4,6,8, and 9.

Hope that helps!

Step-by-step explanation:

for the rest of the question when it asks "which scenario fits the compound inequality?"

diagonal = 9√2 ≈ 12.73

the diagonal splits the square into 2 right triangles with the hypotenuse being the diagonal of the square

using Pythagoras' identity

d = √(9² + 9²) = √162 = 9√2 ≈ 12.73 ( to 2 dec. places )

To find the diagonal of a square with side lengths of 9 inches, use the Pythagorean theorem, yielding a diagonal length approximately equal to 9√2 inches.

To calculate the diagonal of a square, you can use the Pythagorean theorem for a right triangle formed by two adjacent sides of the square and the diagonal. The formula for the diagonal (d) of a square with side length (s) is given by d = s√2. Therefore, the diagonal of the square is:

d = 9√2

d = 9 × 1.414 (approx)

d = 12.726 inches (approx)

Rounded to the nearest whole number or given options, the length of the diagonal is closer to 9√2 inches.

The complete question is:

A square has a side lengths of 9, use the pythagorean theorem to find the length of the diagonal of the square.

Answer:

77.57

If we round.

78

Step-by-step explanation:

To solve this, just plugin 70 where the x is located in the equation:

y = -0,414x + 106.55

y = -0,414(70) + 106.55 = 77.57

The best prediction for the percentage of people would be 78 % in an audience finish watching a documentary that is 70 minutes long.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The regression equation is given by:

y = -0.414x + 106.55

Here y represents the percentage of people in an audience who finish watching a documentary.

and x represents the length of the film in minutes.

We have to determine the value of y when the value of x is: 70

Substitute the value of x = 70 in the equation,

y = -0.414x + 106.55

y = -0.414(70) + 106.55

y = 77.57

Therefore, the best prediction for the percentage of people would be 78 % in an audience finish watching a documentary that is 70 minutes long.

#SPJ2

Answer:

Area of the Scale drawing is [tex]72[/tex] square inches.

Step-by-step explanation:

First we need to convert feet and inches to a common unit. For that lets convert feet into inches.

1 feet = 12 inches

Therefore,

The length of the floor in inches:

[tex]36[/tex] feet = [tex]36*12[/tex] inches

                           =[tex]432[/tex] inches

The width of the floor in inches:

[tex]32[/tex] feet = [tex]32*12[/tex] inches

                           =[tex]384[/tex] inches

Now lets calculate by how many times the length has been scaled down:

432 inches of length has been reduced to 9 inches.

[tex]\frac{432}{9}=48[/tex]

So the length has been scaled down 48 times.

Now lets scale down the width 48 times:

[tex]\frac{384}{48} =8[/tex]

So the width of the Scale drawing is 8 inches.

Area of the Scale drawing = Scaled down length * Scaled down width

                                            =[tex]9*8[/tex]

                                            =[tex]72[/tex] square inches

Answer:

72 square inches.

Step-by-step explanation:

Convert feet and inches.

36 feet = 36*12  inches

                          =432 inches

Width of the floor; Converted from feet to inches:

32 feet = 32*12  inches

                          = 384 inches

Calculate how many times the length (l) has been scaled down.

432 inches of length has been reduced to 9 inches.

[tex]\frac{432}{9}=48[/tex]

Now the length has been scaled down 48 times.

Scale down the width (w) 48 times.

[tex]\frac{384}{48} =8[/tex]

The width of the scale drawing = 8 in

Area of the Scale drawing = Scaled down length * Scaled down width

                                        [tex]=9*8 =72in^{2}[/tex]

When you want a parallel line through a given point (h, k), you can start with the equation you have and do the following:

Here, that looks like

... (y-(-100)) = -2(x-(-100))

... y = -2x -200 -100 . . . . . eliminate parentheses, add -100

... y = -2x -300 . . . . the equation you want.

Answer:

y = - 2x - 100

Step-by-step explanation:

Remark

The line we want is a line parallel to y = - 2x + 3

That means it has the same slope as the given line.  The given line has a slope of  -2

y = -2x + b is what you have so far. Now you have to use the point to get b

y = - 100

x = - 100

Solve for b

-100 = -2(-100) + b

-100 = 200 + b       Notice the sign change. Two minus's make a plus. Subtract 200 from both sides.

- 100 - 200 = b

- 300 = b

Answer

y = - 2x - 100

A

this is a geometric sequence since there exists a common ratio r between the terms

r = [tex]\frac{21}{7}[/tex] = [tex]\frac{63}{21}[/tex] = [tex]\frac{189}{63}[/tex] = 3

B

to obtain the next term in the sequence multiply the previous term by 3

[tex]a_{n+1}[/tex] = 3 [tex]a_{n}[/tex] ← recursive rule

C

the n th term of a geometric sequence is

[tex]a_{n}[/tex] = [tex]a_{1}[/tex] [tex]r^{n-1}[/tex]

where [tex]a_{1}[/tex] is the first term in the sequence

[tex]a_{n}[/tex] = 7 × [tex]3^{n-1}[/tex] ← explicit rule

The most accurate way to estimate 33% of 52 is explained as follows:

To find a percentage, we calculate it as follows:

a% of b [tex]=\frac{a}{100} \times b[/tex]

Now, lets convert 33% into fraction first:

33% [tex]=\frac{33}{100} =0.33[/tex]

Now,

[tex]0.33 \times 52=17.16 \approx 17[/tex]

We have two ways to calculate the same so we will compare the values of them and figure out which gives a value nearer to our actual value:

So, [tex]\frac{1}{3} \times51=17[/tex] and [tex]\frac{1}{3} \times 53=17.66[/tex]

We can see that the first method gives us a value which is far closer to the actual value.

Therefore, [tex]\frac{1}{3} \times 51[/tex] is the most accurate way to estimate 33% of 52.

Answer:

28 minutes.

Step-by-step explanation:

We can see from our graph that 12 minutes after starting the race Lynn left Kael behind and he ran at a greater speed till the race ended after 40 minutes.

To find total number of minutes Lynn ran faster than Kael we will subtract 12 from 40.

[tex]40-12=28[/tex]

Therefore, Lynn ran at a greater speed than Kael for 28 minutes.

Answer:

28 minutes

Step-by-step explanation:

There are two pairs of digits such that one is 8 more than the other: 0, 8 and 1, 9.

Since 0 is not one of the digits of the number in question, that number must be ...

... 91

Answer:

The correct answer is option A.

Step-by-step explanation:

For the given triangles to be similar the segment AD must be an altitude of ΔABC.

We can provide a theorem for the same:

If we draw an altitude from the right angle of any right triangle, then the two triangles formed are similar to the original triangle.

Also all the three triangles are similar to each other.

Like here, in the triangle ABC, we draw an altitude from A to the side BC, thus forming 2 triangles; ΔDBA and ΔDAC. These both will be similar to ΔABC.

So, by the theorem it is proven that  ΔABC is similar to ΔDBA.

Therefore, option A is correct.

You can use the sum of angles identities, then rearrange to put the result in the form of tangents.

[tex]\displaystyle\frac{\sin{(x+y)}}{\sin{(x-y)}}=\frac{\sin{(x)}\cos{(y)}+\cos{(x)}\sin{(y)}}{\sin{(x)}\cos{(y)}-\cos{(x)}\sin{(y)}}\\\\=\frac{\left(\frac{\sin{(x)}\cos{(y)}+\cos{(x)}\sin{(y)}}{\cos{(x)}\cos{(y)}}\right)}{\left(\frac{\sin{(x)}\cos{(y)}-\cos{(x)}\sin{(y)}}{\cos{(x)}\cos{(y)}}\right)}\\\\=\frac{\tan{(x)}+\tan{(y)}}{\tan{(x)}-\tan{(y)}}[/tex]

Find the slope first, use the formula (y₁-y₂)/(x₁-x₂)

[6-(-2)]/(-1-7) = 8/-8 -> -1              Therefore your slope (mx) is -x.

To find the y-intercept, you use one of the points and substitute it in the slope intercept formula: y=mx+b, using the slope you just found.

-2=-1(7)+b

-2=-7+b -> -2+7=b

b=5

In conclusion, your equation will be y=-x+5. I hope this helped ;)

Answer:

3.8 feet

Step-by-step explanation:

Given that the person is standing in a pool.  That means he is keeping his feet at the bottom level of the pool.  His height is 6.2 ft.  

Top of the person head above the surface of water= 2.8 feet.

Hence height of the person= Top of the person head above the surface of water+depth of the pool

6.2 = 2.8+depth of pool

Depth of pool = 6.2-2.8 = 3.4 feet.

the pool is four feet deep

First, I should point out that g(x) should be written as g(x)=(x+2)/3, otherwise the problem is confusing.  

[tex]f(x)=3x-2 \enspace g(x)=\frac{x+2}{3}[/tex]

(A) [tex]f(g(x))=3(\frac{x+2}{3})-2=x\\g(f(x))=\frac{3x-2+2}{3}=x[/tex]

(B) Since [tex]f(g(x))=x[/tex] and [tex]g(f(x))=x[/tex], it holds that

[tex]f(g(x))=g(f(x))[/tex] for all x. This means the composed functions are *identical*

A

f(g(x)) = f([tex]\frac{x+2}{3}[/tex]) = 3([tex]\frac{x+2}{3}[/tex]) - 2 = x + 2 - 2 = x

g(f(x)) = g(3x - 2) = [tex]\frac{3x-2+2}{3}[/tex] = [tex]\frac{3x}{3}[/tex] = x

B

Since both composite functions f(g(x)) and g(f(x)) equal x

This indicates that the functions f(x) and g(x) are inverse functions
