Kevin sells personalized party hats. Each party hat is a cone with a slant length of 9 inches and a radius of 3 inches. How tall is the inside of the party hat? Round your answer to the nearest tenth. *

Answer:

Step-by-step explanation:

because The curve C crosses the x-axis at the origin and at the points A and B =>  the x coordinates of A and B are the solution of the equation:

 x(x + 4)(x - 2) = 0

<=> x = 0

      x = -4

      x = 2

because the x-coordinates of the points A and B aren't 0 and the x-coordinate

of A is a negative value

=>  the x-coordinate of  A is -4

the x-coordinate of B is 2

Algebra I

Step-by-step explanation:

In order for a systems of equations to have a solution set, the 2 graphs must intersect at at least 1 point. Here, we see that graphs 1 and 5 do not intersect each other at all.

Therefore, the rest of the graphs have solutions and #1 and #5 do no have any solutions.

Answer:

The coordinates of mage of L(5, 10) will be: (11, 3)

So, the 4th (last) option is correct.

Step-by-step explanation:

As we know that Translation means how much a point is moved to the left/right and up/down.

As the x-coordinate of the image point K(7, -3) is 7 which is 6 units right to the original point J(1, 4).

Also, the y-coordinate of the image point K(7, -3) is -3 which is 7 units down to the original point J(1, 4)

so it means the translation basically implies that

(x, y) → (x + 6, y - 7)

Hence, the coordinate of the image of L(5, 10) can also be determined by

using the same rule.

(x, y) → (5 + 6, 10 - 7) = (11, 3)

Therefore,  the coordinates of mage of L(5, 10) will be: (11, 3)

So, the 4th (last) option is correct.

Step-by-step explanation:

f(x)+g(x)=(2x^2 + 5x +6) + (3x^2 +4x - 10)

Combine like terms

5x^2 + 9x -4

f(x)-g(x)=(2x^2 + 5x +6) - (3x^2 +4x - 10)

Distribute the negative

(2x^2 + 5x +6) + (-3x^2 -4x + 10)

Combine like terms

-x^2 +x +16

Answer:

Adults =193

children=52

Step-by-step explanation:

Step one:

let the number of tickets adults be x

and the number of tickets children be y

x+y=245--------1

6.5x+3y=1410.5---2

Step two:

solve the system of equation using substitution

x+y=245

x=245-y

put x=245-y in equation 2 we have

6.5(245-y)+3y=1410.5

1592.5-6.5y+3y=1410.5

-6y+3y=1410.5-1592.5

-3.5y=-182

y=182/3.5

y=52

put y=52 in x=245-y

x=245-52

x=193

Step-by-step explanation:

Answer:

x ≥ [tex]\frac{21}{5}[/tex]

Step-by-step explanation:

Given

[tex]\frac{5}{18}[/tex] - [tex]\frac{x-2}{9}[/tex] ≤ [tex]\frac{x-4}{6}[/tex]

Multiply through by 18 ( the LCM of 18, 9 and 6 ) to clear the fractions

5 - 2(x - 2) ≤ 3(x - 4) ← distribute parenthesis and simplify

5 - 2x + 4 ≤ 3x - 12

9 - 2x ≤ 3x - 12 ( add 2x to both sides )

9 ≤ 5x - 12 ( add 12 to both sides )

21 ≤ 5x ( divide both sides by 5 )

[tex]\frac{21}{5}[/tex] ≤ x , that is

x ≥ [tex]\frac{21}{5}[/tex]

Answer:

get from (4,1) to (2,9) go up 8 and over 2 left (-2) - (4 - 2, 1 + 8), do this again (2 - 2, 9+8) and end up at (0,17) which is the y how do you change 7x+3y=3 into slope intercept form.

Answer:

Slope: 0

Y-intercept: 2

Step-by-step explanation:

Answer:

Slope = 0

Y-intercept = 2

Step-by-step explanation:

Hello!

The slope of the graph is how much the graph rises, compared to how much the graph runs.

As you can see here, the graph rises by 0, but runs infinetely, giving a slope of 0.

The y-intercept of the graph is where the graph intersects the y-axis.

The y-intercept here is 2, because it crosses the y-axis at (0,2).

Answer:

y=2x+3

Step-by-step explanation:

1. y+7=2(x+5) (rewrite the problem)

2. y+7=2x+10 (distribute the 2)

3. y=2x+3 (subtract 7 from both sides; 10-7=3)

Answer:

y + 9 = [tex]\frac{1}{5}[/tex](x + 4)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = [tex]\frac{1}{5}[/tex] and (a, b) = (- 4, - 9) , thus

y - (- 9) = [tex]\frac{1}{5}[/tex](x - (- 4) ) , that is

y + 9 = [tex]\frac{1}{5}[/tex](x + 4)

Step-by-step explanation:

Answer:

5 <= y <= 85

Step-by-step explanation:

Since the lowest weight possible is 5lbs (just the barbell and no weights) the lowest point of the range is 5lbs (the y intercept when x = 0)

The highest weight possible is 85lbs since, there is only 8 pairs of weight plates (8 is the input value) and the pairs each weigh 10lbs (the slope of the graph) + 5lbs from the barbell (y-intercept).

Using the function given, if you input 8 as the x value, you get

85 = 10(8) + 5

So the highest value of the range is 85lbs, therefore the range is 5 <= y <= 85.

Solve the compound interest problem. ​$3425 is invested at ​%7.5 compounded monthly for 2 years. a. Find the overall amount. b. Find the compound interest.

Answer:

$3977.425 ; $552.425

Step-by-step explanation:

Given that:

Principal (P) = $3425

Rate (r) = 7.5% = 0.075

Time(t) = 2 years

A = p(1 + r/n)^nt

r = rate

n = number of times compounded per year

t = time in years

A = final amount

A = 3425(1 + 0.075/12)^12*2

A = 3425(1 + 0.00625)^24

A = 3425(1.00625)^24

A = 3425(1.1612920)

A = $3977.4251

Hence, overall amount = $3977.425

Compound interest = $(3977.425 - 3425) = $552.425

Answer: C. 7.25, 7.7, 7 1 7

Step-by-step explanation:

From the question, we are given the weight , in ounces, of three different packages of cookies and we are told to arrange them in ascending order that is, from the least to the greatest.

The least of the numbers is 7.25. After then we have 7.7 and the greatest is 717. Therefore this can be arranged as:

7.25, 7.7, 7 1 7

Therefore, the correct option is C.

===============================

Explanation:

Use the vertical line test. If it is at all possible to draw a single vertical line through more than one point on the relation curve, then the relation is not a function. This is because a function is only possible when any x input leads to exactly one y output.

So that's why graphs 1,2,3 are not functions, while graphs 4,5,6 are functions.
