3x4^2=144 determin if true

With Cos s=-2/5 and sin t=4/5, s and t are in quadrant 4,  cos(s+t) and cos(s-t) is mathematically given as

cos(s+t)= 0.493

cos(s-t)= 0.97321

Question Parameter(s):

Cos s=-2/5 and sin t=4/5, s and t are in quadrant 4

Generally, the equation for the s and t as functions of the 4 qudrants is mathematically given as

cos(s+t) = cos(s)*cos(t) - sin(s)*sin(t)

Therefore

cos(s+t)= -4/5 * [tex](-\sqrt{21}[/tex]/5) - (-3/5)*(-2/5)

cos(s+t)= 4*[tex]\sqrt{21}/[/tex]25 - 6/25

cos(s+t)= 0.493

In conclusion,

cos(s-t) = cos(s)*cos(t) + sin(s)*sin(t)

cos(s-t)= -4/5 * (-[tex]\sqrt{21}/[/tex]5) + (-3/5)*(-2/5)

cos(s-t)= 4[tex]*\sqrt{21}[/tex]/25 + 6/25

cos(s-t)= 0.97321

Answer:

$459

Step-by-step explanation:

Given the following question:

32% of 675

To find the answer to this question we need to use the formula to calculate 32% of 675. Then we subtract that answer from our original price which will then give us our answer.

[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{32\times 675}{100}[/tex]
[tex]32\times675=21600[/tex]
[tex]21600\div100=216[/tex]
[tex]=216[/tex]

Subtract from the original price:
[tex]675[/tex]
[tex]675-216=459[/tex]
[tex]=459[/tex]

The television after a 32% discount will cost "$459."

Hope this helps.

Answer:

  x -4y = -24

Step-by-step explanation:

Given the equation of a line in standard form, you can write the equation of the perpendicular line by swapping the coefficients and negating one of them. The constant needs to be adjusted to make the equation true at the point you want the line to pass through.

  4x +y = 7 . . . . given line

  x -4y = constant . . . . equation with coefficients swapped, one negated

  x -4y = (-4) -4(5) = -24 . . . . equation with appropriate constant

An equation for the desired line is ...

  x -4y = -24

__

Additional comment

The standard form equation has a positive leading coefficient, so the choice of which coefficient to negate will take that into account.

The slope of the standard form line ...

  ax +by = c

is m = -a/b.

The slope of the perpendicular line is the opposite reciprocal of this:

  m' = -1/m = b/a

You can see that this swaps the coefficients and negates one of them.

The triangle ABC is a right triangle

The length of AC is 12.00 cm

From the figure, we have the following parameters:

Length AB = 13 cm

Angle A = 22.6 degrees

Represent the length AC with b.

So, we have the following cosine ratio

[tex]\cos(A) = \frac{b}{AB}[/tex]

Substitute known values

[tex]\cos(22.6) = \frac{b}{13}[/tex]

Make b the subject

[tex]b = 13 * \cos(22.6)[/tex]

Evaluate the product

[tex]b = 12.00[/tex]

Hence, the length of AC is 12.00 cm

The equation to describe this situation is that Bobby's cat and dog were 6 miles apart after 30 minutes is 0.5x = 6

Since Bobby's cat runs at x mph, its speed is x mph.

Also, Bobby's dog runs twice as fast as his cat. So, his dog's speed is v = 2x.

Since they both move a distance in t = 30 min = 30 min × 1 h/60 min = 0.5 h.

Bobby' cat's distance in 30 mins is d = x × 0.5 h

= 0.5x miles

Also, Bobby's dog covers a distance in 30 min, D = v × 0.5 h

= 2x × 0.5 h

= x miles

Since Bobbys cat and dog were 6 miles apart after 30 min, we have that

D - d = 6

x - 0.5x = 6

0.5x = 6

So, the equation to describe this situation  that Bobby's cat and dog were 6 miles apart after 30 minutes is 0.5x = 6

Answer:

m∠C = 98°

Step 1: Derive an Equation

To solve this problem, we will use what is called the Exterior Angle Theorem. This states that in a triangle, the measure of an exterior angle is equal to the sum of the measures of its 2 corresponding remote interior angles.

In this case, the exterior angle is ∠T (the obtuse one) and the remote interior angles are ∠C and ∠Y. Therefore, m∠T = m∠C + m∠Y.

Substituting the given measures into the equation, we get:

[tex]3x+2+x=130[/tex]

Step 2: Solve the Equation

[tex]3x+2+x=130[/tex]

[tex]4x+2=130[/tex] (Combine like terms)

[tex]4x=128[/tex] (Subtract 2 from both sides to isolate [tex]x[/tex])

[tex]x=32[/tex] (Divide both sides by 4 to get rid of [tex]x[/tex]'s coefficient)

Step 3: Answer the Question

We now know what [tex]x[/tex] is. Therefore, m∠C = [tex]3*32+2=\bf 98 \textdegree[/tex].
