If m∠A = (3x-6)° and m∠B = (x + 9)°, find the m∠D.
A) 32°
B) 39°
C) 41°
D) 49°
E) None of the above

Answers

Because line BD goes through the center of the circle Angle A is a right angle which equals 90 degrees.

Set the equation for A to equal 90 and solve for x:

3x-6 = 90

Add 6 to each side:

3x = 96

Divide both sides by 3:

x = 32

Now we have a value for x , use that to solve for angle b:

B = x +9 = 32 + 9 = 41 degrees.

Now we know A and B, we can solve for D.

The three inside angles of a triangle need to equal 180.

D = 180 - 90 - 41 = 49 degrees.

The answer is D) 49

A circular spa has a 12 foot diameter and a constant depth of 3.5 feet. What is the water
volume of this spa?​

Answers

volume of a cylinder : v = πr²h

v= 3.14x6x6x3.5 = 395.64

volume of a circular spa : v = πr²h

v= 3.14 x 6 x 6 x 3.5 = 395.64

Measure the circular base to get the diameter.Divide the diameter by 2 to get the radius.Calculate the area with the formula: A = πr^2, where r is the radius.Measure the height of the cylinder.Multiply the area by the height to get the Volume.

The volume of a cylinder is equal to the product of the area of the circular base and the height of the cylinder. The volume of a cylinder is measured in cubic units.

Calculate the area of the circular base

To the formula for finding the area of a circle, A = πr2.[6] Just plug the radius you found into the equation. Here's how to do it:

A = π x 12

A = π x 1

A = π

Since π is normally rounded to 3.14, you can say that the area of the circular base is 3.14 in.2

To find the nth term of a geometric series with first term 2 and common ratio 4, the formula [tex]a * r^(n-1)[/tex] is used.

For the 14th term, apply 2 * [tex]4^(13)[/tex] to get 134,217,728.

The student has asked for the rule to find the nth term of a geometric series and for the 14th term specifically. The first term is given as 2, and the common ratio is 4.

In a geometric series, the nth term is found using the formula[tex]a * r^(n-1)[/tex], where a is the first term and r is the common ratio. To find the 14th term, we would use the formula [tex]2 * 4^(14-1)[/tex].

Let's calculate the 14th term:

Substitute the given values into the formula: 2 * [tex]4^(13)[/tex].Calculate 4 raised to the 13th power, which is 67,108,864.Multiply this result by the first term, which is 2, to get the 14th term: 134,217,728.

what is the 17th term in the arithmetic sequence in which a6 is 101 and a9 is 83

Answers

Answer:

35

Step-by-step explanation:

We know that the general formula for arithmetic sequence is  

a_n=a_0+(n-1)d

Using the general formula, we can make equations for 6th term and 9th term

a_6=a_0+(6-1)d

a_6=a_0+5d

101=a_0+5d Eqn 1

For 9th term

a_9=a_0+(9-1)d

a_9=a_0+8d

83=a_0+5d   Eqn 2

Subtracting equation 2 from equation 1

101-83=a_0+5d-(a_0+8d)

18=a_0+5d-a_0-8d  

18=-3d

d= -6

Putting d=-6 in Eqn 1, we get:

101=a_0+5(-6)

101=a_0-30

a_0=101+30

a_0=131

Now that we have values of a_0, and d we can find the 17th term

a_17=a_0+(17-1)d

=131+(16)(-6)

=131-96

=35

So the 17th term is 35 ..

The map below shows the location of 3 houses where you had to do lawn work today. Your truck gets 8 miles per gallon of gasoline, so you chose the shortest route from your house to the jobs and then back home, as shown below. If gas costs $1.52 per gallon, what was the total cost of the gas that you used today?

Answers

Answer:

$3.80

Step-by-step explanation:

We are given a graph showing the location of 3 houses where you had to do lawn work today, with the distances from your house.

Given that one truck gets 8 miles per gallon of gasoline and gas costs $1.52 per gallon, we are to find the total cost of the gas used.

Total distance = 7 + 3 + 4 + 6 = 20 miles

Gallons of gas used = 20 / 8 = 2.5

Total cost of gas used = 2.5 * 1.52 = $3.80

Which of the following is the correct equation for this function?
A. y= (x+4)(x+2)
B. y=x^2+ 3x – 2
C. y+ 2 = – 2(x+3)^2
D. y+ 2 = 2(x+3)^2

Answers

Answer:

The equation which is correct for the given function is:

           D.   [tex]y+2=2(x+3)^2[/tex]

Step-by-step explanation:

By looking at the graph we observe that the graph of the function passes through the point (-4,0) , (-2,0)  , (-3,-2)

A)

         [tex]y=(x+4)(x+2)[/tex]

when x= -3 we have:

[tex]y=(-3+4)(-3+2)\\\\y=1\times (-1)\\\\y=-1\neq -2[/tex]

Hence, option: A is incorrect.

B)

     [tex]y=x^2+3x-2[/tex]

when x= -2 we have:

[tex]y=(-2)^2+3\times (-2)-2\\\\y=4-6-2\\\\y=-4\neq 0[/tex]

Hence, option: B is incorrect.

C)

    [tex]y+2=-2(x+3)^2[/tex]

when x= -2 we have:

[tex]y+2=-2(-2+3)^2\\\\y+2=-2[/tex]

[tex]y=-4\neq 0[/tex]

Hence, option: C is incorrect.

D)

   [tex]y+2=2(x+3)^2[/tex]

We see that the graph of this equation matches the given graph of the function.

Answer:

[tex]3-\sqrt{11}[/tex]

Step-by-step explanation:

The function [tex]f(x)[/tex] has a grade of 4, becaus it has 4 roots.

Now, if one of its roots is [tex]3+\sqrt{11}[/tex], it means there fourth is [tex]3-\sqrt{11}[/tex], because square roots have two results, one positive and one negative.

According to the Rational Root Theorem, the following are potential roots of f(x) = 6x4 + 5x3 - 33x2 – 12x + 20.
Which is an actual root of f(x)?

a) -5/2
b) -2
c) 1
d) 10/3

Answers

Answer:

a) -5/2.

Step-by-step explanation:

Try substituting (-5/2) into f(x):

6(-5/2)^4 + 5(-5/2)^3 - 33(-5/2)^2 - 12(-5/2) + 20

= 234.375 + -78.125 - 206.25 + 30 + 20

= 0.

So it is -5/2.

Answer:

a) [tex]x= -5/2[/tex]

Step-by-step explanation:

We substitute in the function the values given in the options to confirm whether they are roots or not

a) [tex]x= -5/2[/tex]

the function will be:

[tex]f(-\frac{5}{2} )=6(-\frac{5}{2} )^4 + 5(-\frac{5}{2} )^3-33(-\frac{5}{2} )^2-12(-\frac{5}{2})+20[/tex]

simplifying:

[tex]f(-\frac{5}{2} )=6(\frac{625}{16} )-5(\frac{125}{8} )-33(\frac{25}{4} )+30+20[/tex]

[tex]f(-\frac{5}{2} )=234.375-78.125-206.25+50\\f(-\frac{5}{2} )=0\\\\[/tex]

since the function when [tex]x= -5/2[/tex] is equal to zero, this is an actual root of f(x).

Answers

Answer:

see explanation

Step-by-step explanation:

Given

2x² + 7x = 15 ( subtract 15 from both sides )

2x² + 7x - 15 = 0 ← in standard form

To factorise the left side

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 2 × - 15 = - 30 and sum = + 7

The factors are + 10 and - 3

Use these factors to split the x- term

2x² + 10x - 3x - 15 ( factor the first/second and third/fourth terms )

2x(x + 5) - 3(x + 5) ← factor out (x + 5) from each term

4. [tex]12+ 3y[/tex] cannot be simplified any further.

5. [tex]12-3y+x[/tex] cannot be simplified any further.

6. [tex]5 + 2y + 7x - 4x + 3y - 17 = -12 + 5y + 3x[/tex]
