Answers

18 jars

12 divided by 2 is 6.

We know each day Brad jars 6.

6 x 3 = 18

Answer:

18 liters

Step-by-step explanation:

We can use ratios to solve

12 liters      x liters

----------- = -----------

2 days       3 days

Using cross products

12 *3 = 2x

To hard sorry try Socratic it’s a app that helps with math problems

solve 2x−3y=−1 , 3x+4y=24

Answers

Let’s start with 2x-3y=-1–>y=2/3x+1/3 then substitute that in for y in the second equation: 3x+4(2/3x+1/3) then solve for x; once x has been found substitute the value of x into either of the equations and evaluate it to find y
Use the elimination method for systems of equations.

Your answer should be x = 3

Plug the x value into one of the equations and you should get y = 7/3

The solution is (3, 7/3)

A. 42°F
B. 90°F
C. 58°F
D. 122°F

Answers

Answer:

D, 122°F

°F = 9/5°C + 32

°F = 9/5(50) +32

°F = 90 + 32

°F = 122

a projectile is thrown upwards from an initial height of 1584 feet so that it's distance above the ground after t seconds is modeled by the given function.
h(t)=-16t^2+480t+1584.

what is the maximum height it will reach?​

Answers

Answer:

5184 ft

Step-by-step explanation:

Given

A quadratic function

h(t)= -16t^2+480t+1584.

Its maximum is its vertex

Vertex formula for ax^2 + bx + c is

x = -b/2a

Applying this to our function

t = -480/2(-16) = 15

Maximum height is reached after 15 seconds and is

h(15) = -16*15^2 + 480*15 + 1584 = 5184 ft

Three friends entered a race around a track. Edward takes 6 minutes to run one lap. Bernie takes 3 minutes to run one lap and it takes Freddie 5 minutes to run one lap. If all three friends begin the race at the same time, how many minutes will it take for all three friends to be at the starting point again?

Answers

Answer:

It will take 30 minutes

Step-by-step explanation:

Here, we want to calculate the time it will take for the three friends to be at the starting point again

What we do here is to note the time it will take for each of the three friends to run a lap

That will be 6 , 3 and 5

What we now need to know the time is to find the lowest common multiple of the three amount of time

The lowest common multiple of 6,3 and 5 is 30

So the amount of time it will take the friends to be at the starting point again is 30 minutes

Answer:k=−a3−a2b−36a−36b+217/a2+ab

         

Step-by-step explanation:Step 1: Flip the equation.

a3+a2b+a2k+abk+36a+36b=217

Step 2: Add -a^3 to both sides.

a3+a2b+a2k+abk+36a+36b+−a3=217+−a3

a2b+a2k+abk+36a+36b=−a3+217

Step 3: Add -a^2b to both sides.

a2b+a2k+abk+36a+36b+−a2b=−a3+217+−a2b

a2k+abk+36a+36b=−a3−a2b+217

Step 4: Add -36a to both sides.

a2k+abk+36a+36b+−36a=−a3−a2b+217+−36a

a2k+abk+36b=−a3−a2b−36a+217

Step 5: Add -36b to both sides.

a2k+abk+36b+−36b=−a3−a2b−36a+217+−36b

a2k+abk=−a3−a2b−36a−36b+217

Step 6: Factor out variable k.

k(a2+ab)=−a3−a2b−36a−36b+217

Step 7: Divide both sides by a^2+ab.

k(a2+ab)

a2+ab

=

−a3−a2b−36a−36b+217

k=

Which transformation is shown by the coordinates below? L (-1, 9) M (-8, 8) N (-3, 5) L '(- 9, -1) M' (- 8, -8) N '(- 5, -3) A. Reflection over the x-axis / B. Translation 8 units left and 8 units down / C. Rotation 90 degrees clockwise / D. Rotation 270 degrees clockwise

Answers

Answer:

D. Rotation 270 degrees clockwise.

Step-by-step explanation:

The transformation used in the coordinates below was a rotation 270 degrees clockwise, whose definition is:

[tex](x', y') = (r\cdot \cos (\theta - 270^{\circ}), r\cdot \sin (\theta -270^{\circ}))[/tex]

Please note that clockwise rotation is represented by the minus sign.

Where [tex]r[/tex] is the norm of original point, defined as:

[tex]r =\sqrt{x^{2}+y^{2}}[/tex], [tex]\forall \,x,y\in \mathbb{R}[/tex]

And [tex]\theta[/tex] is the direction of the point centered at origin and with respect to +x semiaxis, measured in sexagesimal degrees:

[tex]\theta = \tan^{-1} \frac{y}{x}[/tex]

Now we proceed to prove the statement:

[tex]L (x, y) = (-1, 9) \longrightarrow L'(x,y)[/tex]

Norm

[tex]r = \sqrt{(-1)^{2}+9^{2}}[/tex]

[tex]r = \sqrt{82}[/tex]

Direction

The point is located on 2nd quadrant, which means that [tex]90^{\circ} \leq \theta \leq 180^{\circ}[/tex]. Then:

[tex]\theta = \tan^{-1}\left(\frac{9}{-1} \right)[/tex]

[tex]\theta = 96.340^{\circ}[/tex]

Rotation

[tex]L'(x,y) = (\sqrt{82}\cdot \cos (96.340^{\circ}-270^{\circ}),\sqrt{82}\cdot \sin (96.340^{\circ}-270^{\circ}))[/tex]

[tex]L'(x,y) = (-9, -1)[/tex]

[tex]M(x,y) = (-8,8) \longrightarrow M'(x,y)[/tex]

Norm

[tex]r = \sqrt{(-8)^{2}+8^{2}}[/tex]

[tex]r = \sqrt{128}[/tex]

Direction

The point is located on 2nd quadrant, which means that [tex]90^{\circ} \leq \theta \leq 180^{\circ}[/tex]. Then:

[tex]\theta = \tan^{-1}\left(\frac{8}{-8} \right)[/tex]

[tex]\theta = 135^{\circ}[/tex]

Rotation

[tex]M'(x,y) = (\sqrt{128}\cdot \cos (135^{\circ}-270^{\circ}),\sqrt{128}\cdot \sin (135^{\circ}-270^{\circ}))[/tex]

[tex]M'(x,y) = (-8, -8)[/tex]

[tex]N(x,y) = (-3,5)\longrightarrow N'(x,y)[/tex]

Norm

[tex]r = \sqrt{(-3)^{2}+5^{2}}[/tex]

[tex]r =\sqrt{34}[/tex]

Direction

The point is located on 2nd quadrant, which means that [tex]90^{\circ} \leq \theta \leq 180^{\circ}[/tex]. Then:

[tex]\theta = \tan^{-1}\left(\frac{5}{-3} \right)[/tex]

[tex]\theta = 120.964^{\circ}[/tex]

Rotation

[tex]N'(x,y) = (\sqrt{34}\cdot \cos (120.964^{\circ}-270^{\circ}), \sqrt{34}\cdot \cos (120.964^{\circ}-270^{\circ}))[/tex]

[tex]N'(x,y) = (-5, -3)[/tex]

Hence, the correct answer is D.

Step-by-step explanation:

Functions can be represented by tables and equations

The function represented by the table is f(x) = x + 1

From the table, we have the following ordered pairs

(x,y) = (-1,0) (0,1) (1,2) and (2,3)

Notice that the difference between the x and y values is 1.

So, we have:

y - x = 1

Add 1 to both sides

y = x + 1

Express as a function

f(x) = x + 1

Hence, the function represented by the table is f(x) = x + 1

What is a mathematical function, equation and expression?function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.equation modelling : Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis and results of the given problem

Given is that the value of a house is $655,000 in cash, but when selling it on installments, you are charged 25.5% of its price.

 

Assume the price when selling on installments be $x. Then, we can write new price as -

[x] = 655000 + {25.5% of 655000}

[x] = 655000 + {25.5/100 x 655000}

[x] = 655000 + {25.5 x 6550}
[x] = 655000 + 167025

[x] = $822025

Therefore, the price when selling on installments be $822025.
