Which expression is equivalent to 3(4x + 2/3) -7x + 3/8

Answer:

24 miles

Step-by-step explanation:

so he went 6 miles, then 8 miles, then diagonally home.

which means he ran in a triangle.

Use the Pythagorean theory.

6*6=36

8*8=64

36+64=100

what square root = to 100?

10

so the questions is total moles did clay run.

6+8+10=24 miles

Answer:

$20,400.00

Step-by-step explanation:

so, they're paying 4.25% of $5,000 every month for 8 years.

well, first lets see how many payments were made.

8 x 12 = 96 payments

4.25% of 5,000 is 212.5

so 96 payments of $212.5 is...

$20,400.00

dang, that's a lot of money.

Step-by-step explanation:

Quadratic Equation

Quadratic equation is in the form

ax2+bx+c=0

Where

a, b, & c = real-number constants

a & b = numerical coefficient or simply coefficients

a = coefficient of x2

b = coefficient of x

c = constant term or simply constant

a cannot be equal to zero while either b or c can be zero

Examples of Quadratic Equation

Some quadratic equation may not look like the one above. The general appearance of quadratic equation is a second degree curve so that the degree power of one variable is twice of another variable. Below are examples of equations that can be considered as quadratic.

1. 3x2+2x−8=0

2. x2−9=0

3. 2x2+5x=0

4. sin2θ−2sinθ−1=0

5. x−5x−−√+6=0

6. 10x1/3+x1/6−2=0

7. 2lnx−−−√−5lnx−−−√4−7=0

For us to see that the above examples can be treated as quadratic equation, we take example no. 6 above, 10x1/3 + x1/6 - 2 = 0. Let x1/6 = z, thus, x1/3 = z2. The equation can now be written in the form 10z2 + z - 2 = 0, which shows clearly to be quadratic equation.

Roots of a Quadratic Equation

The equation ax2 + bx + c = 0 can be factored into the form

(x−x1)(x−x2)=0

Where x1 and x2 are the roots of ax2 + bx + c = 0.

Quadratic Formula

For the quadratic equation ax2 + bx + c = 0,

x=−b±b2−4ac−−−−−−−√2a

See the derivation of quadratic formula here.

The quantity b2 - 4ac inside the radical is called discriminat.

• If b2 - 4ac = 0, the roots are real and equal.

• If b2 - 4ac > 0, the roots are real and unequal.

• If b2 - 4ac < 0, the roots are imaginary.

Sum and Product of Roots

If the roots of the quadratic equation ax2 + bx + c

= 0 are x1 and x2, then

Sum of roots

x1+x2=−ba

Product of roots

x1x2=ca

You may see the derivation of formulas for sum and product of roots here.

Answer:

About 6 gallons of paint

Step-by-step explanation:

[tex]\frac{0.5}{84}[/tex]  =  [tex]\frac{x}{932}[/tex]

84x=932(0.5)

84x=466

x  =  5.55

round up to get about 6 gallons of paint

The number of the gallon of paint is need will be 5.547 gallons of paint.

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

Joel used a half gallon of paint to cover 84 square feet of wall.

Then in one gallon of paint he can cover 168 square feet.

He has 932 square feet of walls of paint.

Then the number of the gallon of paint is need will be

⇒ 932 / 168

⇒ 5.547 gallons of paint

Answer:

Step-by-step explanation:

The circumference (C) of a circle is calculated as

C = πd ( d is the diameter )

(4)

Here d = 18, thus

C = 18π in

(5)

Here C = 50π, thus

πd = 50π ( divide both sides by π )

d = 50 in

The radius r is one half of the diameter , thus

r = 50 ÷ 2 = 25 in

Assume that it is a right triangle for now

According to the Pythagorean Theorem...

(38)^2 + (56)^2 = (69)^2

4580 ≠ 4761

Both sides are not equal, and hence the Pythagorean Theorem can't be applied to the triangle. It is not a right triangle.

Answer:

The measure of each angle is :

3x° = 33°

(5x+2)° =57°

Step-by-step explanation:

From the diagram, angle <ABC is a right-angle triangle with a measure of 90°

This means the sum of the two angles <ABE + <CBE =90°

Given from the question :

<ABE = 3x°

<CBE = (5x+2)°

For an equation for sum of the two angles as;

<ABE + <CBE =90°

3x° + (5x+2)° = 90° ------collect like terms after opening the brackets

3x° +5x° + 2° =90°

8x°=90°-2°

8x°=88°

x°=88°/8° = 11°

Measure of the angles will be:

<ABE = 3x° = 3*11° = 33°

<CBE = (5x+2)° = (5*11° +2° ) =55°+2°= 57°

Answers are :

3x° = 33°

(5x+2)° =57°

Answer:

  2) 162°, 72°, 108°

  3) 144°, 54°, 126°

Step-by-step explanation:

1) Multiply the equation by 2sin(θ) to get an equation that looks like ...

   sin(θ) = <some numerical expression>

Use your knowledge of the sines of special angles to find two angles that have this sine value. (The attached table along with the relations discussed below will get you there.)

____

2, 3) You need to review the meaning of "supplement".

It is true that ...

  sin(θ) = sin(θ+360°),

but it is also true that ...

  sin(θ) = sin(180°-θ) . . . . the supplement of the angle

This latter relation is the one applicable to this question.

__

Similarly, it is true that ...

  cos(θ) = -cos(θ+180°),

but it is also true that ...

  cos(θ) = -cos(180°-θ) . . . . the supplement of the angle

As above, it is this latter relation that applies to problems 2 and 3.
