WILL GIVE BRAINLIEST find vertex of parabola y=x^2-x

Answer:

It's 50,000 times bigger.

Step-by-step explanation:

3×10¹⁵ ÷ 6×10¹⁰ = (3 ÷ 6)×(10¹⁵÷10¹⁰) = 0.5×10¹⁵⁻¹⁰ = (5×10⁻¹)×10⁵ = 5×10⁻¹⁺⁵ = 5×10⁴ It is 5×10⁴ (= 50,000) times bigger.

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.

how many brownies are there

Answer/Step-by-step explanation:

From the first attachment or we can also say:

https://brainly.com/question/27391854

Base on first attachment:

There are 12 people ⇒ Emily, Delvenal, 10 other friends that was suppose to come

Either :

cut the pan of brownies into the 12 pieces

cut the pan of brownies into 24 pieces

But from this second attachment we know that:

Out of the 10 friend that war suppose to come only 7 came.

Thus if they cut the pan of brownies into 12 pieces then

Emily and delvenal + 7 friend = 10 people

12 - 10 = 2

Hence, 2 pieces of brownies are left.

Thus, if they cut the pan of brownies into 24 pieces then

Emily and delvenal + 7 friend = 10 people

24 - 10 = 14

Hence, 14 pieces of brownies are left.

Answer:

  not a right triangle

Step-by-step explanation:

The side lengths do not meet the requirements of the Triangle Inequality. The given figure is not even a triangle.

_____

Additional comment

The triangle inequality requires the sum of the two short sides exceed the long side:

  3 + 9 > 12 . . . . not true

__

The converse of the Pythagorean theorem tells you that the triangle is a right triangle if the sum of the squares of the short sides is equal to the square of the long side: 3² +9² = 12² (not true). Here, that criterion is not met, so the triangle is not a right triangle.

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]

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.

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

h = 32 inches
