Explanation:

Point B is at the location (x, y)

The x coordinates of A and B are 3 and x respectively. Add them up, divide in half, and set the result equal to the x coordinate of M which is 5

(3+x)/2 = 5

3+x = 2*5

3+x = 10

x = 10-3

x = 7 which is the x coordinate of point B

Repeat this same idea for the y coordinates.

(8+y)/2 = 6

8+y = 2*6

8+y = 12

y = 12-8

y = 4

Therefore, point B is located at (x,y) = (7, 4)

Visual verification is shown below. You could also use the midpoint formula on segment AB to find that M = (5,6) is the midpoint.

A  = p +0.2p

We don't know the value of P, so it stays unknown.

The r is the interest rate as a decimal. we know that r = 0.04 because we're told the interest rate is 4%. Note that 4% = 4/100 = 0.04

The time in years is t = 5

So this means...

A = P + P*r*t

A = P + P*0.04*t ... replace r with 0.04

A = P + P*0.04*5 ... replace t with 5

A = P + P*0.2 ... multiply

A = P + 0.2*P ... swap term

A  = p +0.2p

(A) The expression to represent the elevation level of city D, in feet will be :  [tex]D = \frac{1}{4} * [C][/tex]    
(B) The elevation of city D will be -6 feet. The negative here shows that city D is below sea level.

In the question, it is given that city A is 96 feet below sea level, city C is 24 feet below sea level, and the elevation of city D is 1 over 4th of the elevation of C. Since, City A & C are both below sea level their elevation will be negative. So, by these we get elevations:

For City A,  A = -96

      City C,  C = -24

      City D,  [tex]D = \frac{1}{4} *[C][/tex]      ----> Equation (1)

By Equation (1) we get the representation of elevation for City D.

Now, Calculating the elevation of city D, we will put the value of city C in equation (1).

        =>   [tex]D = \frac{1}{4} *[-24][/tex]

        =>   [tex]D = -6\\[/tex]

The negative sign here shows that the elevation is below sea level for city D.

Hence, the expression representing the elevation of city D will be [tex]D = \frac{1}{4} * [C][/tex] and, the elevation of city D will be -6.

According to the statement

We have to find that the measure of the each angle.

So, For this purpose, we know that the

A figure which is formed by two rays or lines that shares a common endpoint is called an angle.

From the given information:

Two angles a form a linear pair. The measure of one angle is 1/3 the measure of the other angle.

Then

Since the two angles form a linear pair, the sum of their angles is equal to 180°. The condition given in the problem is that one angle is one-third of the other angle, or simply speaking, one angle is three times more than the other angle. We find the values of the angles by dividing the sum of the angles by 4 and assigning 3 and 1 times the dividend.

180°/4 = 45°

By obtaining the dividend, we obtain the values of the angles to be 45°

Answer is  f(x)= [tex]\frac{x^{2}+ 2x - 8 }{x - 5}[/tex]

vertical asymptote, the denominator must be contained (x−5)

and for zeros the numerator must be contained (x−2)

then we get,

So far f(x)= f(x)= [tex]\frac{ (x - 2)}{x - 5}[/tex]

​

For slant asymptote, quotient of numerator divided by denominator must be (x+4)

Therefore:

f(x)= [tex]\frac{(x + 4) (x - 2)}{x - 5}[/tex]

after solving this equation we get,

So f(x)= [tex]\frac{x^{2}+ 2x - 8 }{x - 5}[/tex]

​A vertical asymptote is a vertical line that guides the graph of the function but is not part of it. It can never be crossed by the graph because it occurs at the x-value that is not in the domain of the function. A function may have more than one vertical asymptote.

In Mathematics, a slant asymptote, also known as an oblique asymptote, occurs when the degree of the numerator polynomial is greater than the degree of the denominator polynomial. The slant asymptote gives the linear function which is neither parallel to x-axis nor parallel to the y-axis.

1.37037037 or 1 10/27

Step-by-step explanation:

What's there to explain?

27/27 + 10/27 = 1 10/27

Answer's:

27. vertex: (-4, -5) and x-intercept: (√5 - 4, 0) and (-√5 - 4, 0)

28. vertex: (-5, -11) and x-intercept: (√11 - 5, 0) and (-√11 - 5, 0)

29. vertex: (1, 16) and x-intercept: (-3, 0) and (5, 0)

To find vertex, the quadratic function should be in f(x) = a(x - h)² + k form.

where:

27.

g(x) = x² + 8x + 11

completing square:

g(x) = (x² + 8x) + 11

g(x) = (x + 4)² + 11 - (4)²

g(x) = (x + 4)² - 5

g(x) = (x - (-4))² - 5

To find x-intercept: set y = 0

[tex]\sf (x + 4)^2 - 5 = 0[/tex]

[tex]\sf (x + 4)^2 = 5[/tex]

[tex]\sf x + 4 = \pm \sqrt{5}[/tex]

[tex]\sf x= \sqrt{5}-4, \ - \sqrt{5}-4[/tex]

Hence, the vertex is (-4, -5) and x intercepts (√5 - 4, 0) and (-√5 - 4, 0).

28.

f(x) = x² + 10x + 14

completing square:

f(x) = (x² + 10x) + 14

f(x) = (x + 5)² + 14 - (5)²

f(x) = (x + 5)² - 11

Find x intercept, so y = 0:

[tex]\sf (x + 5)^2 - 11 = 0[/tex]

[tex]\sf (x + 5)^2 = 11[/tex]

[tex]\sf x + 5 = \pm\sqrt{11}[/tex]

[tex]\sf x = \sqrt{11} -5, \ -\sqrt{11} -5[/tex]

Hence, the vertex is (-5, -11) and x intercepts (√11 - 5, 0) and (-√11 - 5, 0).

29.

f(x) = -(x² - 2x - 15)

f(x) = -((x² - 2x)) + 15

f(x) = -(x - 1)² + 15 + (-1)²

f(x) = -(x - 1)² + 16

Find the x-intercept's:

[tex]\sf -(x - 1)^2 + 16 = 0[/tex]

[tex]\sf -(x - 1)^2 = -16[/tex]

[tex]\sf (x - 1)^2 = 16[/tex]

[tex]\sf x - 1 = \pm\sqrt{16}[/tex]

[tex]\sf x - 1 = \pm4[/tex]

[tex]\sf x = -3, \ 5[/tex]

Step-by-step explanation:

Vertex form of a quadratic function:

[tex]\boxed{y=a(x-h)^2+k}[/tex]

where:

Given function:

[tex]g(x)=x^2+8x+11[/tex]

Change to vertex form by completing the square.

Add and subtract the square of half the coefficient of x:

[tex]\implies g(x)=x^2+8x+11 +\left(\dfrac{8}{2}\right)^2-\left(\dfrac{8}{2}\right)^2[/tex]

[tex]\implies g(x)=x^2+8x+11 +16-16[/tex]

[tex]\implies g(x)=x^2+8x+16+11-16[/tex]

[tex]\implies g(x)=x^2+8x+16-5[/tex]

Factor the perfect trinomial:

[tex]\implies g(x)=(x+4)^2-5[/tex]

Therefore, the vertex is (-4, -5).

To find the x-intercepts, set the function to zero and solve for x:

[tex]\begin{aligned}g(x) & = 0\\\implies (x+4)^2 -5 & = 0\\(x+4)^2 & = 5\\\sqrt{(x+4)^2} & = \sqrt{5}\\x+4&=\pm\sqrt{5}\\x+4-4&=-4\pm\sqrt{5}\\x&=-4\pm\sqrt{5}\end{aligned}[/tex]

Therefore, the x-intercepts are:

[tex]x = -4+\sqrt{5}, \quad x = -4-\sqrt{5}[/tex]

---------------------------------------------------------------------

Given function:

[tex]f(x)=x^2+10x+14[/tex]

Change to vertex form by completing the square.

Add and subtract the square of half the coefficient of x:

[tex]\implies f(x)=x^2+10x+14+\left(\dfrac{10}{2}\right)^2-\left(\dfrac{10}{2}\right)^2[/tex]

[tex]\implies f(x)=x^2+10x+14+25-25[/tex]

[tex]\implies f(x)=x^2+10x+25+14-25[/tex]

[tex]\implies f(x)=x^2+10x+25-11[/tex]

Factor the perfect trinomial:

[tex]\implies f(x)=(x+5)^2-11[/tex]

Therefore, the vertex is (-5, -11).

To find the x-intercepts, set the function to zero and solve for x:

[tex]\begin{aligned}f(x) & = 0\\\implies (x+5)^2 -11 & = 0\\(x+5)^2 & = 11\\\sqrt{(x+5)^2} & = \sqrt{11}\\x+5&=\pm\sqrt{11}\\x+5-5&=-5\pm\sqrt{11}\\x&=-5\pm\sqrt{11}\end{aligned}[/tex]

Therefore, the x-intercepts are:

[tex]x = -5+\sqrt{11}, \quad x = -5-\sqrt{11}[/tex]

---------------------------------------------------------------------

Given function:

[tex]f(x)=-(x^2-2x-15)[/tex]

Change to vertex form by completing the square.

Add and subtract the square of half the coefficient of x:

[tex]f(x)=-\left(x^2-2x-15+\left(\dfrac{-2}{2}\right)^2-\left(\dfrac{-2}{2}\right)^2\right)[/tex]

[tex]f(x)=-\left(x^2-2x-15+1-1\right)[/tex]

[tex]f(x)=-\left(x^2-2x+1-15-1\right)[/tex]

[tex]f(x)=-\left(x^2-2x+1-16\right)[/tex]

Factor the perfect trinomial:

[tex]f(x)=-\left((x-1)^2-16\right)[/tex]

Simplify:

[tex]f(x)=-(x-1)^2+16[/tex]

Therefore, the vertex is (1, 16).

To find the x-intercepts, set the function to zero and solve for x:

[tex]\begin{aligned}f(x) & = 0\\\implies -(x-1)^2 +16 & = 0\\(x-1)^2 -16 & = 0\\(x-1)^2 & = 16\\\sqrt{(x-1)^2} & = \sqrt{16}\\x-1&=\pm4\\x-1+1&=1\pm4\\x&=5,-3\end{aligned}[/tex]

Therefore, the x-intercepts are:

Given that, a doctor administers a drug to a ​34-kg ​patient, using a dosage formula of ​55mg/kg/day.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the number of tablets should a 34​-kg patient takes every four​ hours to be x.

Now, 55 × 34 = 1870 mg/day

For every four hours:

1870 × 1 /24 × 4 = 311.666

≈312 mg per 4 hours

So, x=312/4 × 1/300 = 78 × 0.0033

Liquid suspension is for every 12 hours:

So, 312/12 × 1/200 = 26 × 0.005 = 0.13 mL

The values of the piecewise function is g(1) = 3, g(2) = 1 / 2, g(3) = 1 / 4.

Piecewise functions are functions consisting in two or more expression constrained by intervals. In this case, we find a piecewise function formed by three equations. In this exercise we need to evaluate the function, whose expression depends on the x-value to be used. There are three values to be evaluated:

x = 1

g(1) = (1 + 1)² - 1

g(1) = 2² - 1

g(1) = 4 - 1

g(1) = 3

g(2) = - (1 / 4) · 2 + 1

g(2) = - (1 / 2) + 1

g(2) = 1 / 2
