the q value moves the graph in q units upward or downward and has ____________ on the _____________ of the parabola​

Answer:

<A = right angle

<B = acute angle

<C = obtuse angle

<D = acute angle

Step-by-step explanation:

Right angle = 90 degrees

Acute angle = less than 90 degrees

Obtuse angle = more than 90 degrees

∠A = 90° is a right angle, ∠B = 60° and ∠D  = 70° are acute angles,

and ∠C = 140° is an obtuse angle.

We have,

The quadrilateral ABCD.

There are four angles:

∠A = 90°
∠B = 60°

∠C = 140°

∠D = 70°

An acute angle is an angle whose measure is less than 90 degrees.

An obtuse angle is an angle whose measure is greater than 90 degrees but less than 180 degrees.

A straight angle is an angle whose measure is 90 degrees.

Using the definition,

∠A = 90°

This is a right angle.
∠B = 60°

This is an acute angle.

∠C = 140°

This is an obtuse angle.

∠D = 70°

This is an acute angle.

Thus,

∠A = 90° is a right angle, ∠B = 60° and ∠D  = 70° are acute angles,

and ∠C = 140° is an obtuse angle.

Answer:

x = 3

y = 2

z = -3

Step-by-step explanation:

L1         x + 2y + z = 4

L2      2x - y + 4z = - 8  

L3    - 3x + y - 2z = - 1

2L1 - L2

2x + 4y + 2z = 8

-2x +   y - 4z =  8

------------------------------

         5y - 2z = 16        L4

3L1 + L3

3x + 6y + 3z = 12

-3x +   y  - 2z = -1

-----------------------------

        7y +  z = 11            L5

L4 + 2L5

 5y - 2z = 16

14y + 2z = 22

--------------------------

19y        = 38

y = 38 / 19

y = 2

7y +  z = 11

7(2) + z = 11

14 + z = 11

z = 11 - 14

z = -3

x + 2y + z = 4

x + 2(2) + (-3) = 4

x + 4 - 3 = 4

x + 1 = 4

x = 4 - 1

x = 3

Answer:

The parallel equation is y=[tex]\frac{5}{2}[/tex]x-5.

The perpendicular equation is y=[tex]\frac{-2}{5}[/tex]x-5.

Step-by-step explanation:

First solve for y.

-5x+2y=8

2y=5x+8

y=[tex]\frac{5}{2}[/tex]x+4

A line is parallel if it has the same slope, but different y-intercepts.

The y-intercept of the given point is -5, so the new slope will be y=[tex]\frac{5}{2}[/tex]x-5

To find a perpendicular line, you find the negative reciprocal of the given slope.

So you find [tex]\frac{-1}{\frac{5}{2} }[/tex], which is equal to [tex]\frac{-2}{5}[/tex].

The perpendicular equation is y=[tex]\frac{-2}{5}[/tex]x-5.

Step-by-step explanation:

4 - 515x + 2 = - 36

or, -515x = -36-2-4

or, 515x = 42 [multiplying with (-1) in both sides]

or, x = 42/515

Answer:

56

Step-by-step explanation:

0.14 gallons/sec * 50 sec = 7 gallons

There are 8 pints per gallon.

7 gallons * 8 pints/gallon = 56 pints

Given that a running tap dispenses 0.14 gallons of water every second. Using unitary method, 56 pints of water is dispensed after 50 seconds.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Water dispensed every second =  0.14 gallons

Water dispensed after 50 seconds = 0.14 * 50 = 7 gallons = 7 * 8 = 56 pints (1 gallon = 8 pints)

Answer:

[tex]x=6\\y=12[/tex]

Step-by-step explanation:

To find the value of x you can use sin rule

[tex]sin(60)=\frac{oppoaite}{hypotenuse}\\\frac{\sqrt{3} }{2} =\frac{x}{4\sqrt{3} } \\[/tex]

Use cross multiplication

[tex]4*\sqrt{3} *\sqrt{3} =2x\\4*3=2x\\12=2x\\\frac{12}{2} =\frac{2x}{2} \\6 =x[/tex]

To find the value of y you have to use sin rule again

[tex]sin(30)=\frac{opposite}{hypotenuse}\\\frac{1}{2} =\frac{x}{y} \\\frac{1}{2} =\frac{6}{y} \\[/tex]

Use cross multiplication

[tex]y=6*2\\y=12[/tex]
