Answer:

[tex]\textsf{C)}\quad 3x-45=10[/tex]

Step-by-step explanation:

Given equation:

[tex]\dfrac15x-3=\dfrac23[/tex]

Multiply both sides by 3:

[tex]\implies 3\left(\dfrac15x-3\right)=\dfrac23 \cdot 3[/tex]

[tex]\implies \dfrac{3 \cdot 1}{5}x-3 \cdot 3=\dfrac{2 \cdot 3}{3}[/tex]

[tex]\implies \dfrac35x-9=2[/tex]

Multiply both sides by 5:

[tex]\implies 5\left(\dfrac35x-9\right)=2 \cdot 5[/tex]

[tex]\implies \dfrac{5 \cdot 3}{5}x-5 \cdot 9=10[/tex]

[tex]\implies 3x-45=10[/tex]

Answer:

its A beacuse

Step-by-step explanation:

Simplifying

41n(7x) = 8

Remove parenthesis around (7x)

41n * 7x = 8

Reorder the terms for easier multiplication:

41 * 7n * x = 8

Multiply 41 * 7

287n * x = 8

Multiply n * x

287nx = 8

Solving

287nx = 8

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Divide each side by '287x'.

n = 0.02787456446x-1

Simplifying

n = 0.02787456446x-1

The choice that matches the graph of the function as is defined to Graph A.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

A graph contains data of which input maps to which output.

Analysis of this leads to the relations which were used to make it.

The given function are;

f(x)= 2 ,if 2 < x ≤ 4

f(x)= 4, if 4 < x ≤ 6

f(x)= 6  ,if 6 < x ≤ 8

This means that how we get the staircase pattern as shown in graph A. This is considered a piecewise function since we're graphing pieces of various other functions.

Hence, the choice that matches the graph of the function as is defined to Graph A.

Part A: x = -5/4, 3 || (-5/4, 0) (3, 0)

To find the x-intercepts, we need to know where y is equal to 0. So, we will set the function equal to 0 and solve for x.

4x^2 - 7x - 15 = 0

4 x 15 = 60 || -12 x 5 = 60 || -12 + 5 = -7

4x^2 - 12x + 5x - 15 = 0

4x(x - 3) + 5(x - 3) = 0

(4x + 5)(x - 3) = 0

4x + 5 = 0

x = -5/4

x - 3 = 0

x = 3

Part B: minimum, (7/8, -289/16)

The vertex of the graph will be a minimum. This is because the parabola is positive, meaning that it opens to the top.

To find the coordinates of the parabola, we start with the x-coordinate. The x-coordinate can be found using the equation -b/2a.

b = -7

a = 4

x = -(-7) / 2(4) = 7/8

Now that we know the x-value, we can plug it into the function and solve for the y-value.

y = 4(7/8)^2 - 7(7/8) - 15

y = 4(49/64) - 49/8 - 15

y = 196/64 - 392/64 - 960/64

y = -1156/64 = -289/16 = -18 1/16

Part C:

First, start by graphing the vertex. Then, use the x-intercepts and graph those. At this point we should have three points in a sort of triangle shape. If we did it right, each of the x-values will be an equal distance from the vertex. After we have those points graphed, it is time to draw in the parabola. Knowing that the parabola is positive, we draw in a U shape that passes through each of the three points and opens toward the top of the coordinate grid.

Hope this helps!

Answer:

Give the other guy brainliest

Step-by-step explanation:

Part A: The x-intercepts are (-5/4, 0) and (3, 0)

0=4x^2-7x-15

0=4x^2-12x+5x-15

0=4x(x-3)+5(x-3)

0=(4x+5)(x-3)

Basic math:

x=-5/4

x=3

Part B: The vertex is going to be minimum because if a>0, then the parabola opens up and it is a minimum (a as in ax^2+bx+c).

In order to find the vertex's coordinates, we can use -b/2a. In the equation, b=-7, and a=4. The formula would look like or 7/8. We now know the x coordinate. We can use that to find the y value.

y=4(7/8)^2-7(7/8)-15=y=18  =-18.0625=289/16

Part C: Graph the x-intercepts found in part A, then graph the vertex found in part B. Then graph a U shape that opens up going through all the points to make the parabola. Because it is positive, the U will face up, not down.

Answer:

the mode that repeats the most is 2.2 becuase to find it you need to find the number that repeats the most in the table. To find the median you add all the numbers and divide them to get the answer that is 2.7 for the mean but to find the median you need to order them from least to greatest and the answer you get for the median is 2.6 so hopefully that is the correct answer for all of them.

   4        *       9/4     *     23/4   = 51.75 in^3

Answer: 3: 50.24

Step-by-step explanation: 3: because to find the circumferrence you would do 3.14×8 the radius 25.12×2= 50.24, now with that try the other 2

The height of a cone with a volume and base area of 2,144.7 cubic inches and 201.1 square inches respectively is 32 inches

volume of a cone = 1 / 3 πr²h

where

Therefore,

volume of the cone =  2,144.7 cubic inches

Base area = 201.1 square inches.

πr² = Base area

Therefore,

2144.7  = 1 / 3 × 201.1  × h

6434.1 = 201.1 h

h = 6434.1 / 201.1

h = 31.9945300845

Answer: NO

Step-by-step explanation:

This is because if you think about it, only the people that want to do the survey do it. Those who dont want to do it dont have to. This makes it voluntary. Any time the surveyed person gets to choose if they can do it it is voluntary. Furthermore, If it is voluntary it can usually represent all of the different peoples. But in this case, the shy people dont get a say because they would choose to not survey. So the shy people would not be represented. That is why this isn't random.

Answer:

volume=Length x width x height

so area is Length x width, therefore you would just take 2,025 and divide by 9 to get 225 sq. ft for the area.

Step-by-step explanation:

Answer:

227 square feet

Step-by-step explanation:

The volume of a rectangular prism is given by the formula ...

V = Bh

where B is the area of the base, and h is the height.

Filling in the given information, we have ...

2043 ft³ = B·(9 ft)

Dividing by the coefficient of B gives its value:

B = (2043 ft³)/(9 ft) = 227 ft²

The area of the floor is 227 square feet.
