ANSWER

B) (m+p,n+r)

The coordinates are :

A(2m,2n)

B(2p,2r)

To find the x-coordinate of the midpoint of AB, we add the x-coordinates of the two points and divide by 2.

[tex]x = \frac{2m + 2p}{2} [/tex]

Factor

[tex]x = \frac{2(m + p)}{2} [/tex]

Simplify:

[tex]x = m + p[/tex]

Similarly, the y-coordinate is

[tex]y = \frac{2n + 2r}{2} [/tex]

[tex]y = \frac{2(n + r)}{2} [/tex]

[tex]y = (n + r)[/tex]

Hence the midpoint is

Answer:

[tex]b = 17[/tex]

Step-by-step explanation:

For this triangle we have to

[tex]a=18.2\\B=62\°\\C=48\°[/tex]

We want to find the length of b

We know that the sum of the internal angles of a triangle is 180 °

So

[tex]A + 62 +48=180\\\\A=180-62-48\\\\A=70\°[/tex]

Now we use the sine theorem to find the length of b:

[tex]\frac{sin(A)}{a}=\frac{sin(B)}{b}=\frac{sin(C)}{c}[/tex]

Then:

[tex]\frac{sin(A)}{a}=\frac{sin(B)}{b}\\\\b=\frac{sin(B)}{\frac{sin(A)}{a}}\\\\b=a*\frac{sin(B)}{sin(A)}\\\\b=(18.2)\frac{sin(62)}{sin(70)}\\\\b=17[/tex]

Answer:

A =  617 yd², to the nearest yard

That distance is called the "circumference," and its formula is C = 2πr.

We need r to find the area of the park.  So we solve C = 2πr for r:

          C

r   = -------    

        2π

Substituting 88 yd for C, we get r = (88 yd) / (6.28) = 14.01 yd

The formula for the area of this circular park is A = πr².

Here, r = 14.01 yd, so the area of this park is:

A = π(14.01 yd)² = 3.14(196.36 yd²) = 617 yd², to the nearest yard.

The area of the park is [tex]A = 617 yd^2[/tex], to the nearest yard.

That distance is called the circumference and

We have to determine the area of the park

The circumference of the circle is C = 2πr.

We need r to find the area of the park.

So we solve C = 2πr for r:

[tex]r=\frac{C}{2\pi}[/tex]

Substituting 88 yd for C,

We get r = (88 yd) / (6.28)

r= 14.01 yd

The formula for the area of this circular park is

A = πr².

Here, r = 14.01 yd, so the area of this park is,

Answer:

[tex]P (t) = 580e ^ {0.18t}[/tex]   or  [tex]P (t) = 580 (1.18) ^ t[/tex]

Step-by-step explanation:

There are two models of exponential growth that you can use to predict the population of bacteria after t hours.

I) [tex]P (t) = pe ^ {rt}[/tex]

II) [tex]P (t) = p (1 + r) ^ t[/tex]

Where

p is the initial population of bacteria

r is the growth rate

t is the time in hours.

In this case we know that:

[tex]p = 580\\\\r = \frac{18}{100}\\\\r = 0.18[/tex]

Then the equations that can be used to predict the population of bacteria after t hours are:

I) [tex]P (t) = 580e ^ {0.18t}[/tex]

II)[tex]P (t) = 580 (1 + 0.18) ^ t[/tex]

Answer:

(5, - 9)

Step-by-step explanation:

Given

f(x) = (x - 8)(x - 2) ← in factored form

Find the zeros by equating f(x) to zero, that is

(x - 8)(x - 2) = 0

Equate each factor to zero and solve for x

x - 8 = 0 ⇒ x = 8

x - 2 = 0 ⇒ x = 2

The vertex lies on the axis of symmetry which is located at the midpoint of the zeros, hence

[tex]x_{vertex}[/tex] = [tex]\frac{8+2}{2}[/tex] = 5

Substitute x = 5 into f(x) for corresponding y- coordinate

f(5) = (5 - 8)(5 - 2) = (- 3)(3) = - 9

vertex = (5, - 9)

Answer: (5,-9)

Step-by-step explanation:

Make the multiplication indicated:

[tex]f(x) = x^2-2x-8x+16[/tex]

Add the like terms:

[tex]f(x) = x^2-10x+16[/tex]

Now find the x-coordinate of the vertex with this formula:

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

In this case:

[tex]b=-10\\a=1[/tex]

Then:

[tex]x=\frac{-(-10)}{2(1)}=5[/tex]

Rewrite the expression with [tex]f(x)=y[/tex]

[tex]y = x^2-10x+16[/tex]

Now substitute [tex]x=5[/tex] into the function to find the y-coordinate of the vertex:

[tex]y = (5)^2-10(5)+16[/tex]

[tex]y =-9[/tex]

Therefore, the vertex is:

interest earned= 1853.98

the future value of an annuity= 2453.98

Step-by-step explanation:

Given Data:

Interest rate= 9%

time,t = 16 years

Semi-Annual payment, P= 600

n= 2 as Semi-Annual

At the end of 16 years, final investment A= ?

As per the interest formula for compounded interest

A= P(1+r/n)^nt

Putting the values in above equation

= 600(1+0.09/2)^32

= 2453.98

Interest earned = A-P

                          = 2453.98-600

                          = 1853.98 !

Answer:

Options A and D.

Step-by-step explanation:

To check the identities we have to check each option given.

A. tan(x - π) = tanx

We take left hand side (L.H.S.) of the equation.

tan(π - x) = tanx [ since we know tan(π ± x) = tanx ]

So L.H.S. = R.H.S.

It's an identity.

B. sin(x + y) + sin(x - y) = 2cosx siny

We take L.H.S. first

sin(x + y) + sin(x - y)

= sinx coxy + siny cosx + sinx cosy - cosx siny

= 2sinx cosy ≠ R.H.S.

Option B is not an identity.

C. cos(x + y) - cos(x - y) = 2cosx cosy

We take L.H.S. of the equation.

cos(x + y) - cos(x - y) = cosx cosy - sinx siny - (cosx cosy + sinx siny)

= -2sinx siny ≠ R.H.S.

Therefore, option C is not an identity.

D. cos(x + y) + cos(x - y) = 2cosx cosy

We take L.H.S. of the equation.

cos(x + y) + cos(x - y) = cosx cosy - sinx siny + cosx cosy + sinx siny

                                  = 2cosx cosy = R.H.S.

Therefore, option D is an identity.

Options A and D are the identities.

Answer:

Option C is correct.

Step-by-step explanation:

Equation 1 |4x − 3|− 5 = 4

Adding +5 on both sides

|4x − 3|− 5 +5 = 4 +5

|4x − 3| = 9

Apply absolute rule:

IuI = a and a>0 then u = a and u = -a

so, 4x-3 = 9 and 4x-3 = -9

Solving

4x = 9+3   and 4x = -9+3

4x = 12      and 4x = -6

x = 12/4     and x = -6/4

x = 3          and x = -3/2 or -1.5

Equation 2 |2x + 3| + 8 = 3

Adding -8 on both sides

|2x + 3| + 8 -8 = 3 -8

|2x + 3|  = -5

Apply absolute rule:

IuI = a and a>0 then u = a and u = -a

But we cannot apply absolute rule because in our case a < 0 i.e -5

So, Equation 2 has no solutions.

Hence Option C The solutions to equation 1 are x = 3, −1.5, and equation 2 has no solution is correct.

Answer:

The correct answer option is H. 4374.

Step-by-step explanation:

We are given the following geometric sequence and we are to find its 8th term:

[tex]\frac{2}{9}, \frac{2}{3}, 2,...[/tex]

Here [tex]a_1=\frac{2}{9}[/tex] and common ratio [tex](r) = \frac{\frac{2}{3} }{\frac{2}{9} } =3[/tex].

The formula we will use to find the 10th term is:

nth term = [tex]a_1 \times r^{(n-1)}[/tex]

Substituting the values in the formula to get:

10th term = [tex]\frac{2}{9} \times 3^{(10-1)}[/tex]

10th term = 4374

Answer:

Part 1) The center is the point [tex](20,0.05)[/tex]

where

(h,k) is the center of the circle

r is the radius of the circle

In this problem we have

[tex](x-20)^{2}+(y-0.05)^{2}=81[/tex]

Answer:

64 inches  : cross-section, cube, 16 inches

26 inches  : right rectangular prism, 10x 3 x 14 inches

48 inches  : cube with 12-inches edges

34 inches : rectangular prism, 5x12x4 diagonal of 13 inches

Step-by-step explanation:

right rectangular prism, 10x 3 x 14 inches

The cross-section is parallel to the base, so it cuts the height, maintaining the length and width.  So, we have:

P = 10 + 3 + 10 + 3 = 26 inches

cube with 12-inches edges

This time, the cross-section is done perpendicular to the base, but in this case it doesn't matter since it's a cube... so it could be done in any direction and it wouldn't change the result.

P = 12 + 12+ 12 + 12 = 48 inches

rectangular prism, 5x12x4 diagonal of 13 inches

The cut is done perpendicular to the base, but along a diagonal of 13 inches, so the height is preserved, and the diagonal length becomes the new side other than height.

P = 13 + 4 + 13 + 4 = 34 inches

cross-section, cube, 16 inches

Again, the cross-section is done parallel to the base, but in this case it doesn't matter since it's a cube... so it could be done in any direction and it wouldn't change the result.

P = 16 + 16 + 16 + 16 = 64 inches.

Final answer:

The probability that a given event does not occur in any of the trials when an experiment is repeated n times is calculated using the formula (1 - P(A))^n, where P(A) is the probability of the event occurring in a single trial.

Explanation:

The question is about finding the probability that a given event does not occur in any of the trials when an experiment is repeated n times. Let's denote the probability of the event occurring as P(A) and the probability of the event not occurring as P(~A). The probability that an event does not occur in a single trial is 1 - P(A). Therefore, if the experiment is repeated n times independently, the probability that the event does not occur in any of these trials is given by (1 - P(A))^n. This formula arises from the principle that for independent events, the probability of both events A and B occurring is the product of their individual probabilities, P(A) and P(B). Since each trial is independent, and we are looking for the event not happening across all n trials, we multiply the probability of it not happening in one trial by itself n times.

Answer:

The correct answer option is A. positive.

Step-by-step explanation:

When an exponent or a power is an even number and the base is a negative number, the value is always positive.

Suppose we have a negative base [tex] - 3 [/tex] and a power which is even, lets say, [tex] 6 [/tex] so what we get is a positive value.

[tex](-3)^6=729[/tex]

Therefore, a negative base with even power is always a positive value.

Answer: A. positive

Step-by-step explanation:

We know that powers are written in this form:

[tex]b^m[/tex]

Where "b" is the base and "m" is the exponent.

By definition, the exponent indicates how many times to base must be multiplied by itself. Then, if the base is negative and the exponent is an even number, you get:

[tex](-3)^4=(-3)(-3)(-3)(-3)=81\\\\\\(-2)^2=(-2)(-2)=2\\\\\\(-5)^6=(-5)(-5)(-5)(-5)(-5)(-5)=15,625[/tex]

Therefore, when an exponent of a power is an even number and the base is a negative number, the value is always positive.

Step-by-step explanation:

Step 1: List the numbers in order from least to greatest. Take a look at the data and cross out numbers as you place them. There are 16 numbers. The order of these numbers are:

5, 8, 8, 10, 10, 10, 11, 12, 12, 14, 17, 17, 19, 20, 20, 21

Step 2: Cross out numbers from each side to the furthest left and right. By the time you do this, the remaining numbers should be 12 and 12.

Step 3: Find the median. Because there are two numbers left, you do this by adding the two remaining numbers and divinding them by 2. However, because they are the same number, you can safely say that the median is 12.
