Answers

Answer:

  KE = 100 J

Step-by-step explanation:

The question is asking you to use the formula with the values ...

  m = 8 kg . . . . . this 'm' stands for mass

  v = 5 m/s . . . .  this 'm' stands for meters

Putting these values into the formula, we have ...

  KE = 1/2(8 kg)(5 m/s)² = 100 kg·m²/s²

The units are equivalent to the derived SI unit "joules", abbreviated J.

The kinetic energy of the 8 kg mass is 100 J.

B)
Vertex = (5,4), y-intercept = (0,-21), x-intercepts = (-7,0) and (-3,0), axis of

D)
Vertex = (-5,-4), y-intercept = (21,0), x-intercepts = (3,0) and (7,0), axis of

Answers

The features of the quadratic function f(x) = x^2 + 10x + 21  are Vertex = (-5,-4), y-intercept = (0,21), x-intercepts = (-7,0) and (-3,0), axis of symmetry is x = -5 so option (A) will be correct.

What is a quadratic equation?

An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, and a must not be zero.

For example 3x² + 6x + 8 = 0 here x has highest term as 2 and coefficient of x² is not zero.

The standard form of a quadratic equation is ax² + bx + c

The x vertex is given -b/2a

So,

x-vertex = -10/2 = -5

So y = (-5)² + 10(-5) + 21 = -4

So vertex is (-5, -4)

The Y-intercept is given as (0,y)

So,

y = 21

Therefore

y-intercept = (0,21)

the x-intercept is given as (x,0)

So,

x = -7 , -3

Therefore

x-intercepts = (-7,0) and (-3,0)

The Axis of symmetry is given by -b/2a

So,

⇒ -10/2 = -5

Hence "Vertex = (-5,-4), y-intercept = (0,21), x-intercepts = (-7,0) and (-3,0), axis of symmetry is x = -5".

Plz I need help

Answers

Answer:

x= 116/17

Step-by-step explanation:

5x+192−321+13=−12x

Step 1: Simplify both sides of the equation.

5x+192−321+13=−12x

5x+192+−321+13=−12x

(5x)+(192+−321+13)=−12x(Combine Like Terms)

5x+−116=−12x

5x−116=−12x

Step 2: Add 12x to both sides.

5x−116+12x=−12x+12x

17x−116=0

Step 3: Add 116 to both sides.

17x−116+116=0+116

17x=116

Step 4: Divide both sides by 17.

17x/17=116/17

x = 116/17

Find u + v if u = (-4,7, 2) and v = (4,1, -3)

Answers

Answer:   (0, 8, -1)

To get this answer, you add up the corresponding coordinates.

The x coordinates add to -4+4 = 0

The y coordinates add to 7+1 = 8

The z coordinates add to 2+(-3) = -1

Another way to express this is to consider

u = (a,b,c)

v = (d,e,f)

which add to u+v = (a+d,b+e,c+f)

1. Maya's ice cream machine makes 10 cups of ice cream from 0.5 cup of sugar. How many cups of ice cream can be made with 5 cups of sugar?​

Answers

Answer:

100

Step-by-step explanation:

Since ten cups of ice cream is made from .5 cups of sugar, lets first find out how many cups of ice cream can be made form one cup of sugar

.5*2=1

10*2=20

Since the ratio of sugar to ice scream is .5/10 if you do anything to the top you need to do it to the bottom

so now you have 1/20

for every one cup of sugar there are 20 cups of icecream

now you need to multiply both top and bottom by five

1*5=5

20*5=100

5/100

You can make 100 cups of ice cream

*don't forget to label your answer with cups of ice cream*

100 cups of ice cream can be made with 5 cups of sugar.

What are comparing quantities?

Comparing quantities is the qualitative relation between two quantities which reflects the relative size of both the quantities.

It is given that,

10 cups of ice cream requires = 0.5 cup of sugar

⇒ 1 cup of sugar = 10/0.5 cups of ice cream

⇒ 1 cup of sugar = 20 cups of ice cream

Hence we see that Maya's ice cream machine makes 20 cups of ice cream from 1 cup of sugar.

Similarly, 5 cups of sugar = 5 x 20 cups of ice cream

⇒ 5 cups of sugar = 100 cups of ice cream

Therefore,100 cups of ice cream can be made with 5 cups of sugar.
