find the measure of angle A

9514 1404 393

Answer:

  no solution

Step-by-step explanation:

The discriminant is ...

  b^2 -4ac = (-4)^2 -4(2)(16) = 16 -128 = -112

A negative discriminant means there are no real solutions to the equation.

_____

The complex solutions are 1±i√7.

If we assume the equation has a typographical error and is intended to be ...

  2x^2 -4x -16 = 0

The solutions are x = -2 and x = 4.

I'm going to also give you how to get the answer... not just the answer.. you will need to know this for a test :/  so learn it  :P

Step-by-step explanation:

Sin(30)=12

to remember what Sin and Cos at those speacial angles in degrees are.. just use this Sin(degrees)

Sin(0) = 0/2         =0

Sin(30)= [tex]\sqrt{1}[/tex]/2         = 1/2

Sing(45) = [tex]\sqrt{2}[/tex]/2    = [tex]\sqrt{2}[/tex]/2

Sin(60)=[tex]\sqrt{3}[/tex]/2   = [tex]\sqrt{3}[/tex]/2

Sin(90)=[tex]\sqrt{4}[/tex]/2    = 1

Cos is exactly the same but counts backwards from 90°

Cos(90) = 0/2         =0

Cos(60) =  [tex]\sqrt{1}[/tex]/2         = 1/2

Cos(45) = [tex]\sqrt{2}[/tex]/2    = [tex]\sqrt{2}[/tex]/2

Cos(30) = [tex]\sqrt{3}[/tex]/2   = [tex]\sqrt{3}[/tex]/2

Cos(0) =[tex]\sqrt{4}[/tex]/2    = 1

note that the numerators just count from  0,1,2,3,4  , see?  you can remember sin and cos  now  :)   since you can count to 4   :P

Sin(30) =12

1/2 =12  while that statement makes no sense....  obviously 1/2 isn't equal to 12 but.. what's being said is that the angle of 30°  gives you a side that is 12 units long.  

so looking at what I wrote above.. which angle in degrees matches Sin when you look at Cos?  

Sin(30)= 1/2 and Cos(60) also = 1/2  huh

sooo  β = 60 °

got it?  :/

Answer:

11%/ 0.11

Step-by-step explanation:

I=prt

154=700*x*2

154=1400x

divide 1400 by both sides

=0.11

or 11%

Answer:D

Step-by-step explanation:

Answer:

if it increases 8% each year, the next year it's not 8% of the original, but 8% of the 108% and so forth.

The increase after 10 years is (108%)^10 - 100% which is bigger than 80%.

If the value of a stock increases by 8% each year, then, that is not equal to the value of a stock increases 80% each decade.

The degree to which a value increases expressed in percent form is known as percentage increase.

Given that, The value of a stock increases by 8% each year.

a) If it increases 8% each year, the next year it's not 8% of the original, but 8% of the 108% and so forth, the incasement in percentage is an exponential increase not a linear increase, so we can't say that, the value of the stock increases 80% each decade

b) Since,  (108%)¹⁰ > 80%

Hence, the increase after 10 years is (108%)¹⁰, will be bigger than 80%.

Hence, If the value of a stock increases by 8% each year then, that is not equal to the value of a stock increases 80% each decade

Answer:

3x + y = 20 and x - 2y = - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

(a)

Given

3x + y = 17 ( subtract 3x from both sides )

y = - 3x + 17 ← in slope- intercept form

with slope m = - 3

Para;;el lines have equal slopes , then

y = - 3x + c ← is the partial equation

To find c substitute (4, 8) into the partial equation

8 = - 12 + c ⇒ c = 8 + 12 = 20

y = - 3x + 20 ← in slope- intercept form

Add 3x to both sides

3x + y = 20 ← in standard form

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

(b)

Given

y + 2x = 13 ( subtract 2x from both sides )

y = - 2x + 13 ← in slope- intercept form

with slope m = - 2

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-2}[/tex] = [tex]\frac{1}{2}[/tex] , then

y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation

To find c substitute (2, 3) into the partial equation

3 = 1 + c ⇒ c = 3 - 1 = 2

y = [tex]\frac{1}{2}[/tex] x + 2 ← in slope- intercept form

Multiply through by 2 to clear the fraction

2y = x + 4

x - 2y = - 4 ← in standard form

Answer:

what are we supposed to find for this question?

Step-by-step explanation:

Answer:

The product of the first and last digits is 40.

Step-by-step explanation:

Multiple of 4 rule:

The last two digits must form a number that is divisible by 4.

Multiple of 11 rule:

We find the alternate sum of the digits, and it must be divisible by 11.

A SECRET CODE has 5 digits. The middle 3 digits are 926

So the code is

x926y

Divisible by 4:

This means that the 6y must be divisible by 4, which means that the possible values of y are 0, 4, 8.

Value of x when y = 0:

x9260

x - 9 + 2 - 6 + 0 = x - 13

It will be divisible by 11 when x - 13 = 22, that is, x = 9. However, the digit 9 is already used, which means that y = 0 is not a possible option.

Value of x when y = 4:

x9264

x - 9 + 2 - 6 + 4 = x - 9

It will be divisible by 11 when x - 9 = 0, that is, x = 9, which is not possible, as we saw above. Or

x - 9 = 11

x = 2

The digit 2 is also possible, so y cannot be 4.

Value of x when y = 8:

x9268

x - 9 + 2 - 6 + 8 = x - 5

x - 5 = 0 -> x = 5

So, the number is:

59268

What is the product of the first and last digits?

5*8 = 40

The product of the first and last digits is 40.

Answer:

The third graph is correct for the inequality 2x + 3y > -3

Step-by-step explanation:

The slope of the graph is –2/3.

The y-intercept is –1

The area above the dashed be line is shaded.

To verify, choose a coordinate in the shaded area, substitute the values for x and y. Calculate and check.

For example: (1,1)

2(1) + 3(1) > –3

2 + 3 > –3

5 > –3 True.

The graph that represents [tex]2x + 3y > -3[/tex] is (3)

The inequality is given as:

[tex]2x + 3y > -3[/tex]

Subtract 2x from both sides of the inequality

[tex]3y > -3 -2x[/tex]

Divide through by 3

[tex]y > -1 -\frac 23x[/tex]

Rewrite the inequality as follows:

[tex]y > -\frac 23x-1[/tex]

The above inequality means that:

Hence, the graph that represents [tex]2x + 3y > -3[/tex] is (3)
