Answer:

-2

Step-by-step explanation:

You can calculate the rate of the change of the function by calculating the slope which is rise/run. You can do this by starting at (0,1) and going down until the next point lines up on the graph and then going over until you reach the point. You go down two and over to the right one. When going down or left this makes the number negative. In this case -2/1 = -2.

Step-by-step explanation:

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:

Explanation:

The data from the stem-and-leaf plot is:

10,

24,25,26,

30,30,32,33,

40,45,46

Add up those values

10+24+25+26+30+30+32+33+40+45+46 = 341

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

i believe what you need help on is simplifying the equations. so let's start with the first one.

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

(2x+1)(x+5) original problem

(2x)(x)+(2x)(5)+(1)(x)+(1)(5) we can break this down into smaller pieces so we know what we're dealing with in this equation.

2x2+10x+x+5 if we break this down a little more and add some bracket numbers, this is what we get.

2x2+11x+5 this is the most simplified equation.

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

6x−4xy original problem.

unlike the last problem, we can easily just... 6x + (−4xy).

−4xy+6x this is the most simplified equation.

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

ok, the last one. phew!

unfortunately, 16x^2-25 is actually the simplest it can get. so, let's try factoring.

if we factored, we would get...

(4x+5)(4x−5)

wait so like this

\( {189}^{5} \) then the awnser is 241,162,079,949

(189^2)^5

but if it is this

5.81591488E+22

Answer:

5.8159149e+22

should be the answer

see first you would do 189 x 189 or 189² you would get an answer of 35721

Answer:

✔️ 42

Step-by-step explanation:

Area= length x width

first we have to find entire area
12 x 6 = 74

Now find the picture’s area

8 x 4 = 32

Then subtract the area of the whole and the area of the picture to find the are of the frame

74 - 32= 42

Therefore the area of the fame is 42

Step-by-step explanation:

Answer:

60.8π square inches.

Step-by-step explanation:

The label is a rectangle that will be wrapped around a cylinder. So, the area of the label can be found by multiplying the height of the rectangle by the circumference of the cylinder. The circumference of the cylinder can be found by multiplying the diameter by π. Since the two circles in the figure represent the top and bottom faces of the cylinder, the diameter is 2 × 4 = 8 inches. Therefore, the circumference of the cylinder is 8π inches. Thus, the area of the label is:

7.6 × 8π = 60.8π square inches

Therefore, the label is 60.8π square inches.

Answer:

60.8π square inches

Step-by-step explanation:

Chain of thought reasoning: 1. The label is represented by the rectangle in the figure.

2. The area of a rectangle is equal to the width multiplied by the height or A = w x h.

3. The width of the rectangle is equal to the circumference of the circles.

4. The circumference of a circle is equal to 2πr, where r is the radius of the circle.

5. Therefore, the width of the rectangle is equal to 2π x 4 = 8π inches.

6. The height of the rectangle is 7.6 inches.

7. Therefore, the area of the rectangle is equal to 8π x 7.6 = 60.8π square inches.

All of these quadratic equations are in vertex form, which makes it really easy to identify the vertex.

Vertex Form: f(x) = a(x - h)^2 + k

Vertex = (h, k)

As for the quadrants, it is dependent on the positive/negative signs of the x and y coordinates.

---Q1 = (+, +)

---Q2 = (-, +)

---Q3 = (-, -)

---Q4 = (+, -)

y = (x - 3)^2 - 2

Vertex = (3, -2)

Quadrant = Q4

y = (x - 3)^2 + 2

Vertex = (3, 2)

Quadrant = Q1

y = (x + 3)^2 + 2

Vertex = (-3, 2)

Quadrant = Q2

y = (x + 3)^2 - 2

Vertex = (-3, -2)

Quadrant = Q4

Answer:

B)  60%

Step-by-step explanation:

Percentage formula

\(\sf Percentage=\left(\dfrac{Value}{Total\:value}\right) \times 100\)

To find what percent of 200 is 120, substitute the values into the percentage formula:

\(\begin{aligned}\implies \sf Percentage & = \dfrac{120}{200} \times 100\\\\&=\dfrac{120 \times 100}{200}\\\\&=\dfrac{12000}{200}\\\\&=\dfrac{120}{2}\\\\&=60\%\end{aligned}\)

Therefore, 120 is 60% of 200.

An expression is combination of variables, numbers and operators.

We need to find the algebraic expression represents the phrase Six more than the product of 4 and the number of c cups

The phrase Six more than the product of 4 and the number of c cups" can be translated into an algebraic expression as

6 + 4c

more than in the sentence is addition and product is nothing but multiplication.

Therefore, 6 + 4c algebraic expression represents the phrase Six more than the product of 4 and the number of c cups.
