Answer:

Step-by-step explanation:

the given equation

cos(x+y)+cos(x-y)=2cos(x)*cos(y)

[cos(x)cos(y)-sin(x)sin(y)]+cos(x-y)=2cos(x)*cos(y) ..

[cos(x)cos(y)-sin(x)sin(y)]+[cos(x)cos(y)+sin(x)sin(y)]=2cos(x)*cos(y)

[cos(x)cos(y)+cos(x)cos(y)]]+[sin(x)sin(y)-sin(x)sin(y)]=2cos(x)*cos(y) ..

2cos(x)*cos(y)=2cos(x)*cos(y)

Answer:

My answer is = 9 cannot equal 12. There are no variables present in this equation, so what are you solving for?

Step-by-step explanation:

On the right you would use distributive property and on the left you would just simply add and subtract.

However, you cannot equal it to zero either because there are no variables nor exponents.

Answer:

The origin

Step-by-step explanation:

The inequality is origin .(0,0)

Answer:

Angle 6, Angle 8, Angle 2, and Angle 4 are supplementary to Angle 7.

I hope this helped you! If it did, please consider rating, pressing thanks, and marking as Brainliest. Have a great day!

Supplementary angles are the angle whose sum is 180° thus the angles which are supplementary to angle 7 are 8 and 6.

The angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.

The supplementary angle is two angles whose sum is 180°.

It is known that the sum of two angles on a straight line is 180°.

The angles 7 and 8 are on a straight line thus 7 + 8 = 180°.

So, they will be supplementary angles.

Angles 7 and 6 are in a straight line.

Thus, 7 + 6 = 180°.

Hence "Supplementary angles are the angle whose sum is 180° thus the angles which are supplementary to angle 7 are 8 and 6".

Given :

A contestant on a game show must guess the price of a new car. The contestant will  win if his guess is within $1000 of the price of the car.

To Find :

If the price of the car is  $24,995 and the contestant's guess is represented by g, what absolute value  inequality represents this situation.

Solution :

Let, range in which participant guess would be considered correct is r.

So, r should be in range $( 24,995 ± 1000 ).

( 24,995 - 1000 ) ≤ r ≤ ( 24,995 + 1000 )

23,995 ≤ r ≤ 25,995

Therefore, the correct inequality is 23,995 ≤ r ≤ 25,995 .

Hence, this is the required solution.

Step-by-step explanation:

Answer:

slope- 1

y-int- y=2x+-2

Step-by-step explanation:

In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named the "slope-intercept form".

Answer:

x - (-9,0)

y - (0,-18)

Step-by-step explanation:

Answer:

x-intercept = (-9,0)

y-intercept = (0,-18)

Step-by-step explanation:

To find the x-intercept, substitute in  0  for  y  and solve for  x . To find the y intercept, substitute in  0  for  x  and solve for  y .

More than means to add.

Quotient means to divide.

4 + (12/x)

The required expression is 4 + (12/x).

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now the given statement is,

4 more than the quotient 12 and a number x

Now, converting the statement into numerical form.

Since more than is addition.

Thus, 4 more than = 4 +

and, quotient 12 and a number x = 12/x

Thus, 4 more than the quotient 12 and a number x  = 4 +  12/x

this is the required expression.

Thus, the required expression is 4 + (12/x).

Answer:

(2h,0)

Step-by-step explanation:

Answer: Your answer my friend is D, The car stops a distance away from the starting point because the portion shows a constant function away from the starting point.

Step-by-step explanation:

The graph you have explained shows that at J it is a linear or horizonltal line. Whisch means the car is stopped for that period but it is not at the very beginning. Yw

Based on the information given regarding the graph, the correct option is D. The car stops at a distance away from the starting point because the portion shows a constant function away from the starting point.

From the information given, it was stated that the graph shows a journey in a car and that the x-axis is labeled Time in seconds, and the y-axis is labeled distance in miles.

Therefore, the statement that most likely describes the journey at the portion of the graph labeled J is that the car stops at a distance away from the starting point because the portion shows a constant function away from the starting point.

Answer:

The answer is B.

Step-by-step explanation:

Solve for x.

-5x + 5 [tex]\geq[/tex] 160 - 10x

Add 10x to both sides, and subtract 5 from both sides.

5x [tex]\geq[/tex] 155

Now, divide by 5.

x [tex]\geq[/tex] 31          is the answer

The inequality represents all the solutions x ≥ 31. Then the correct option is C.

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

The inequality is given as,

−5x + 5 ≥ 160 − 10x

Simplify the equation, we have

10x – 5x ≥ 160 – 5

         5x ≥ 155

           x ≥ 31

Answer: 0.107

Step-by-step explanation:

En una caja tenemos 8 canicas.

5 son rojas

3 son verdes.

Se retira una canica, y no se remplaza.

Quiero calcular la probabilidad de sacar dos canicas verdes.

La probabilidad de sacar una canica verde en el primer intento, es igual al cociente entre el numero de canicas verdes y el numero total de canicas.

p1 = 3/8  

Ahora, en el segundo intento, en la caja voy a tener 2 canicas verdes (por que ya saque una) y 7 canicas en total. Entonces la probabilidad va a ser:

p2 = 2/7.

Y la probabilidad conjunta (es decir, la probabilidad de sacar las dos canicas de color verde) va a ser igual al producto de las probabilidades individuales.

P = p1*p2 = (3/8)*(2/7) = 0.107

Step-by-step explanation:

Answer:

2, 7, 15, 19, 34

Step-by-step explanation:

First, we have to know what a multiple is. A multiple is a number (n) that can be evenly divided by a certain base number (b). An evenly divided number is one that has no decimal points (ex: 1, 100, 24). For example, the multiples of 8 (b) would be 16, 24, 32, etc (n). Another example would be that 32 is a multiple of 2, 8, 16, etc. since it can be evenly divided by those numbers.

In this case, n = each of the numbers in that list, while b = 4. So now we just have to look at what numbers in our list can be evenly divided by 4.

Since we're asked to find the numbers that are not multiples of 4, our answer to the question would be:

2, 7, 15, 19, 34

Answer:

The required equation is:

[tex]y = -\frac{4}{3}t^2 -\frac{8}{3}t + 4[/tex]

Explanation:

Let us assume that the hole is at y = 0m, with x as the time.

From the question we have (-1s, 8m) as the vertex (here x being the time variable is supposed to be in seconds and y being the distance variable is supposed to be in meters)

At x = 1s, the ball gets to the hole, therefore we have point (1s, 0m)

We know that the vertex of the parabola y = ax² + bx + c is at

[tex]x =\frac{-b}{2a}[/tex]

therefore we have:

[tex]-1 = \frac{-b}{2a}[/tex]

We then have the following equations:

[tex]8 = a\times -1^2 + b\times -1 + c[/tex]

[tex]0 = a\times -1^2 + b\times 1 + c[/tex]

[tex]-1 = \frac{-b}{2a}[/tex]

From the 3rd equation we have

1 X 2a = b.

Therefore we have:

[tex]8 = a\times -1^2 - 1\times 2a\times1 + c[/tex]

[tex]0 = a\times 1^2 + 1 \times2a\times 1 + c[/tex]

We can simplify both equations and get:

[tex]8 = a\times( -1^2 - 2s^2) + c = -a\times 3^2 + c[/tex]

[tex]0 = a\times(1^2 + 2^2) + c = a\times 3^2 + c[/tex]

The first equation now becomes:

[tex]8 = -a\times 3 - a\times 3 = -a\times 6[/tex]

[tex]a = frac{8}{-6} = -\frac{4}{3}[/tex]

With a, we can find the values of c and b.

[tex]c = -a\times3 = -(-\frac{4}{3})*3 = 4 [/tex]

[tex]b = 1\times 2a = 1\times 2(-\frac{4}{3})= -\frac{8}{3}[/tex]

Then the equation is:

[tex]y = -\frac{4}{3}t^2 -\frac{8}{3}t + 4[/tex]
