asking again, will give brainiest !
When multiplying exponents with the same base (ie 4 to the 3rd times 4 to the 5th) you do what to the exponents?

Answer:

$7.80

Step-by-step explanation:

Multiply 0.4 (that is 40%) by 13

It would be 5.2

So subtract 5.2 from $13.00

7.8

So the CD price would be $7.80 with a 40% discount

Hope this helps you :)

Answer:

$5.20

Step-by-step explanation:

First you needed to multiply 0.40 and 13 so that would give you 5.2 so because you are dealing with money you need to add a two after the 2 in 5.2 to make it $5.20. I hope this helped!

Answer:

The equation is 2x = 5y

Step-by-step explanation:

From the question, we are told that what is asked is 2/5 of the price for which each of the items are bought

y is the asking price, x is the original

Mathematically,

that would be;

y = 2/5 * x

y = 2x/5

Thus;

2x = 5y

Answer:

Step-by-step explanation:

The graph of the piecewise function is attached below.

Function is a type of relation, or rule, that maps one input to specific single output.

The piecewise function is given as:

f(x) =  - 6  for  -6< x < 1

       -2x + 5 for  1< x < 6

The above means that we plot the function on their interval or domain.

i.e. we plot f(x) = - 6  on the interval x < 0 and f(x) = -2x + 5 on the interval x < -6

Next, we plot the graph of the piecewise function.

Thus, The graph of the piecewise function is attached below.

Answer:

C

Step-by-step explanation:

sin C=12/13

cos A=12/13

so sin C=cos A

The trigonometric function gives the ratio of different sides of a right-angle triangle. The correct option is C.

The trigonometric function gives the ratio of different sides of a right-angle triangle.

[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}\\\\\\Cosec \theta=\dfrac{Hypotenuse}{Perpendicular}\\\\\\Sec \theta=\dfrac{Hypotenuse}{Base}\\\\\\Cot \theta=\dfrac{Base}{Perpendicular}\\\\\\[/tex]

where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.

Let's solve the given statement as shown below.

A.)

sin C = tan A

sin C = 12/13

tan A = 5/12

Therefore, the given equation is not true.

B. sin C = cos B

sin C = 12/13

cos B = 5/13

Therefore, the given equation is not true.

C. sin C = cos A

sin C = 12/13

cos A = 12/13

Therefore, the given equation is true.

D. sin C = sin A​

sin C = 12/13

Sin A = 5/13

Therefore, the given equation is not true.

Answer:

x=0

Step-by-step explanation:

"x6"   was replaced by   "x^6".

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :7x-(5y*x^6)=0

7x -  5x6y  = 0

7x - 5x6y  =   -x • (5x5y - 7)

-x • (5x5y - 7)  = 0  Hope this helps and you are not stupid everybody has at least something that they dont understand :)))

Answer:

y= -3x-1

Step-by-step explanation:

hope this helps :)

Answer:

y = - 3x - 1

Step-by-step explanation:

The equation in slope- intercept form is

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

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1, - 4) and (x₂, y₂ ) = (2, - 7) ← 2 ordered pairs from the table

m = [tex]\frac{-7+4}{2-1}[/tex] = [tex]\frac{-3}{1}[/tex] = - 3 , thus

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

To find c substitute any ordered pair into the partial equation

Using (1, - 4 ), then

- 4 = - 3 + c ⇒ c = - 4 + 3 = - 1

y = - 3x - 1 ← equation of linear function

Answer: Trevor's argument will be true if he used 100 minutes.

Let x represent the amount of minutes that Trevor would use for the cost of the phone companies to be the same.

Company A charges $35.25 a month, plus $.11/min for local calls. This means that the total cost of making x minutes of call with Company A's plan is

32.25 + 0.11x

Company B charges $14.25 a month, plus $.32/min for local calls. This means that the total cost of making x minutes of call with Company B's plan is

14.25 + 0.32x

For both costs to be the same, the number of minutes would be

35.25 + 0.11x = 14.25 + 0.32x

0.32x - 0.11x = 35.25 - 14.25

0.21x = 21

x = 21/0.21 = 100

QRS = 66° and Q = 95°

Step-by-step explanation:

Required Answer

[tex]\huge {\boxed{\sf{∠QSR=66⁰}}}[/tex]

[tex]\huge {\boxed{\sf{∠Q=95}}}[/tex]

Correct Question:

To find of :

Explanation:

∠QSR+∠QRT=180⁰

Reason:

linear pair

.°. ∠QSR+114⁰=180⁰

∠QSR=180⁰-114⁰

∠QSR=66⁰

Can also be done as follows:

To find value of ∠QSR first we have to find y

y⁰+(5y)⁰=114

Reason:

exterior opposite angle is equal to sum of interior angles

6y=114

y=114/6

y=19

y⁰+(5y)⁰+∠QSR=180⁰

Reason:

sum of angles of triangle =180⁰

6y+∠QSR=180⁰

6×19+∠QSR=180⁰

114+∠QSR=180⁰

∠QSR=180⁰-114⁰

∠QSR=66⁰

From second part we get the value of y

.°.∠Q=5×19

∠Q=95

Answer:

x=3

Step-by-step explanation:

3x-4=8-x(Group like terms)

3x+x=8+4(Add both sides)

4x=12(After adding you will proceed to divide both sides by 4)

x=3(x is 3 because 4 can divide 12 3 times that's why we have x as equal to 3)
