Find the value of x. ​

Answer:

b

Step-by-step explanation:

because of the value of the area

b is the answer

We know, cos A + cos B = 2cos(C+D)/2 × cos(C - D)/2

So,

cos 130 + cos 110 + cos 10

cos 130 + 2cos (110+10)/2 × cos( 110-10)/2

cos 130 + 2cos 60 × cos 50

cos ( 180 - 50 ) + 2cos60 cos 50

We know, cos ( 180 - A ) = -cos A

2cos 60 cos 50 - cos 50

Also, cos 60 = 0.5

2×0.5 cos 50 - cos50

cos 50 - cos 50

0  = RHS.

Hence proved

Answer:

C

Step-by-step explanation:

Since we are given the position function, the average velocity will simply be the average slope of the position function.

We want to find the average velocity for time 0≤t≤3.

So, our endpoints are t = 0 and t = 3.

By substitution, the position of the particle at those times are:

[tex]x(0)=-5(0)^2=0\text{ and } \\\\ x(3)=-5(3)^2=-45[/tex]

So, we have the two points (0, 0) and (3, -45).

Then by the slope formula, we acquire that:

[tex]\displaystyle m=\frac{(-45)-(0)}{(3)-0}=\frac{-45}{3}=-15[/tex]

So, the average velocity of the particle is about -15.

This implies that the particle was mainly moving backwards for time 0≤t≤3.

Hence, our final answer is C.

*If you differentiated first and then did the steps above, then you found the average acceleration of the particle (in this case it stays constant), not the average velocity. Remember that the slope of the position graph is velocity, and the slope of the velocity graph is acceleration!

Answer:

The Jar of peanut butter

Step-by-step explanation:

The easiest way to do this is to calculate price per ounce of each unit.

We'll assign the 12 ounce jar to the variable s and the bulk to the variable b.

First create an equation to find the values of each product per ounce.

Since the 12 ounce jar(s) sells for 3.96 we can say it is 3.96 for every 12 ounces, or s = 3.96/12oz.

Simplify this equation and you get s = 0.33 per ounce.

For b we need to convert pounds to ounces.

There are 16 ounces per pound so the equation we get is:

b = 5.50/16oz

Simplified we get:

b =  about 0.34/oz

The smaller jar has a rate of $0.33/oz

The bulk has a rate of $0.34/oz

This means the answer is b. The jar of peanut butter has a cheaper unit rate.

Answer:

-12

Step-by-step explanation:

5(-10)=-60

-60+15=

-45

Answer:

-12

Step-by-step explanation:

Reorder the terms:

15 + 5x = -45

Solving

15 + 5x = -45

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-15' to each side of the equation.

15 + -15 + 5x = -45 + -15

Combine like terms: 15 + -15 = 0

0 + 5x = -45 + -15

5x = -45 + -15

Combine like terms: -45 + -15 = -60

5x = -60

Divide each side by '5'.

x = -12 :)

Answer:

The expression used to find the nth term of each sequence 9, 17, 25, 33 will be:

Step-by-step explanation:

Given the sequence

9, 17, 25, 33

a₁ = 9

Determining the common difference

d = 17-9 = 8

d = 25-17 = 8

d = 33-25 = 8

As the common difference between the adjacent terms is same and equal to

d = 8

Therefore, the given sequence is an Arithmetic sequence.

An arithmetic sequence has a constant difference 'd' and is defined by  

[tex]a_n=a_1+\left(n-1\right)d[/tex]

substituting a₁ = 9, d = 8 in the equation

[tex]\:a_n=9+8n-8[/tex]

[tex]a_n=8n+1[/tex]

Therefore, the expression used to find the nth term of each sequence 9, 17, 25, 33 will be:

Find the vertex by using the formula:

In this problem, we have:

Using 24 for b and -4 for a, we can substitute these values into the vertex formula:

The h-value for the vertex is 3.

Now let's plug 3 back into the standard form equation to solve for the k-value of the vertex.

The k-value for the vertex is 1.

The vertex of the parabola is (3, 1).

Answer: Your going to have to correct your placing of your numbers.

-12 is value of b for equation 27x²+bx+8=0

A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .

Given,

One of the roots of the equation 27x² + bx + 8 =0 is known to be the square of the other.

We need to find the value of b.

Let one root is a and the other root is a².

(x-a)(x-a²)=0

x²-xa²-ax+a³=0

x²-x(a²+a)+a³=0

Now multiply by 2

x²-2x(a²+a)+2a³=0

x² + bx + 16=0

2a³=16

Divide both sides by 2

a³=8

a=2

27x²-2x(a²+a)+2a³=0

27x²-2x(4+2)+16=0

27x²-2x(6)+16=0

27x²-12x+16=0

b=-12

Hence, -12 is value of b for equation 27x²+bx+8=0
