If Bisector BD bisects ∠ABC. and  ∠ABD= 67°, m∠CBD= 67°then m∠ABC= 134

As given, bisector BD bisects the angle ABC so this means, the angle ABC is divided into two halves. We need to find ∠ABC

So,

angle ABD= angle CBD.

and ∠ABD= (8x + 35)° (i)

∠CBD= (11x + 23)° (ii)

So,

(8x + 35)° = (11x + 23)°

On solving the above equation, we have

3x= 12

x= 4.

Putting x=4 in (i) we have,

∠ABD= 8(4) + 35

∠ABD= 67°

As ∠ABD = ∠CBD, we have

∠CBD= 67°

Now,

∠ABC= ∠ABD + ∠CBD

∠ABC= 67° + 67°

∠ABC= 134°.

Hence, If Bisector BD bisects ∠ABC. and  ∠ABD= 67°, m∠CBD= 67° then m∠ABC= 134

The erosion occurs at a rate of 2/1000 m/years. Over 1,000,000 years, the erosion will be 2,000 meters.

Rate is a ratio between one quantity to another quantity. Rate is also a measure of how fast a quantity changes when another quantity changes. For instance, velocity is a rate to measure the change of distance per amount of travelled time.

Suppose we have two quantities: x and y, with rate of change in y per change in x is denoted by dy/dx, then

y = dy/dx · x

In the given problem:

y = length of erosion

t = time

dy/dt = 2 meters / 1000year = 2/1000 meters/year

Then,

y = dy/dt · t

  = 2/1000 · 1,000,000 = 2,000 meters

Hence, over  1,000,000 years, the regional erosion = 2,000 meters

Step-by-step explanation:

As per given relation about the height of the buildings , the height of building A is 655 feet and height of building B is 855 feet.

As given in the question,

Let us consider height of building A is equal to x feet.

According to given condition height of building A is 200 feet shorter than building B.

Height of building B is equal to ( x + 200 ) feet.

Total height of building A and building B is equal to 1510 feet

Required equation is :

x + x + 200 = 1510

⇒ 2x + 200 = 1510

⇒ 2x = 1510- 200

⇒ 2x = 1310

⇒ x = 655 feet

Height of building B is :

x+ 200 = 655 + 200

            = 855 feet

Therefore, for the given relation about the height of the buildings , the height of building A is 655 feet and height of building B is 855 feet.

Yes, there is enough weight of plastic pellets in a full barrel for the machine to make trash bags for 5 minutes.

It is given that the factory makes trash bags using plastic pellets. The plastic pellets are placed in barrels. The barrels containing the plastic pellets are then poured into a machine. When the machine is operating, the change from a barrel of pellets to the trash bags is 3 kg per minute. Each full barrel contains 18 kg of plastic pellets.

We need to check if there are enough pellets in a full barrel for the machine to make trash bags for 5 minutes. Let the time for which the machine can make the bags from a single barrel of plastic pellets be denoted by the variable "t". The time taken by the machine to fully convert a barrel full of plastic pellets into trash bags is the ratio of the total weight of plastic pellets in the barrel to the rate of conversion of the plastic pellets into trash bags.

t = 18/3

t = 6

Hence, the machine can convert a barrel of plastic pellets into trash bags in a time duration of 6 minutes. So, there are enough pellets in a full barrel for the machine to make bags for 5 minutes.

The value o f c based on The Mean Value Theorem is 1

From the question, we get:

f(a) = f(0)

f(b) = f(2)

Then we need to find the value of both f(0) and f(2):

f(0) = 1 + (0) + (0)²

f(0) = 1 ... (iv)

f(2) = 1 + (2) + (2)²

f(2) = 7 ... (v)

We also need to find the equation for f'(c) based on equation (iii):

f'(x) = 1 + 2x

f'(c) = 1 + 2c ... (vi)

We will input equations (iv) and (v) into equation (i) to find another equation of f'(c):

The remainder when the polynomial  P(x)=x3-x2-2x+8 is divided by (x+2) is 0

Remainder Theorem

From the definition of remainder theorem which stated that , if a polynomial f(x) is divided by a binomial (x−a), then the remainder is f(a)

Using the remainder theorem, P(x)=x3-x2-2x+8 is divided by (x+2).

binominal (x-a)

Step 1: We divide  p(x) by (x + 2)            

P(x)=x3-x2-2x+8  and X = -2

therefore, Remainder = p(-2)

Step 2: Substitute the value of the remainder into p(x)

P(-2) =[tex](-2)^{3}[/tex] -( [tex]-2^{2}[/tex] ) - 2([tex]-2[/tex]) + 8

P(-2) = -8 - 4  + 4 + 8

P(-2) = -12+12

Answer:

Equation is [tex]a_n = 2.50n + 2.50[/tex]

This is discrete

=======================================================

Explanation:

There are n = 12 months in a year.

[tex]a_1[/tex] = first term = x

d = common difference = 2.50, which is the amount the allowance is increasing month to month.

[tex]S_n = \text{Sum of the first n terms of an arithmetic sequence}\\\\S_n = (n/2)*(2a_1 + d(n-1))\\\\S_{12} = (12/2)*(2\text{x} + 2.50(12-1))\\\\S_{12} = 6(2\text{x} + 27.5)\\\\S_{12} = 12\text{x} + 165\\\\[/tex]

The sum of the first n = 12 terms of the arithmetic sequence is 12x+165, where x is the first term (i.e. the allowance on January 1st).

We're told that this total is $225. We'll set the value of [tex]S_{12}[/tex] equal to 225 and solve for x.

[tex]S_{12} = 225\\\\12\text{x} + 165 = 225\\\\12\text{x} = 225 - 165\\\\12\text{x} = 60\\\\\text{x} = 60/12\\\\\text{x} = 5[/tex]

Therefore, you got $5 on January 1st. Then 5+2.50 = 7.50 dollars on February 1st. Then 7.50+2.50 = 10 dollars on March 1st. And so on, until reaching December. All of those dollar amounts then should add to $225 to help confirm the answer.

This equation is discrete because the terms are finite from n = 1 to n = 12. We can't have a midpoint of say between months 3 and 4. It doesn't make sense to have month 3.5 for instance. There's only a set amount of payments.

--------

Now that we know [tex]a_1 = 5[/tex] is the first term, we can then determine the value of any allowance value for any given value of n.

[tex]a_n = \text{nth term of arithmetic sequence}\\\\a_n = a_1 + d(n-1)\\\\a_n = 5 + 2.50(n-1)\\\\a_n = 5 + 2.50n-2.50\\\\a_n = 2.50n + 2.50\\\\[/tex]

Let's see what the allowance would be for month n = 2

[tex]a_n = 2.50n + 2.50\\\\a_{2} = 2.50(2) + 2.50\\\\a_{2} = 5 + 2.50\\\\a_{2} = 7.50\\\\[/tex]

The allowance for month n = 2  (aka February) is $7.50, which was mentioned earlier in the previous section. I'll let you confirm the other values of n.

Keep in mind that n is a positive whole number in the set {1,2,3,...,10,11,12}. It might help to make a table of values.
