Answer: option d.

Step-by-step explanation:

 To solve this problem you must keep on mind the properties of logarithms:

[tex]log(b)-log(a)=log(\frac{b}{a})\\\\log(b)+log(a)=log(ba)\\\\a*log(b)=log(b)^a[/tex]

Therefore, knowing the properties, you can write the expression gven in the problem as shown below:

[tex]5logx+6log(x+7)=logx^5+log(x+7)^6=logx^5(x+7)^6[/tex]

Then, the answer is the option d.

Answer:

D

Step-by-step explanation:

We can use 2 properties of logs to write this as single logarithm:

1. [tex]Log(A^B)=BLog A[/tex]

2. Log x + Log y = Log (x*y)

We can use property #1 to write this as:

[tex]5Logx+6Log(x+7)\\=Logx^{5}+Log(x+7)^{6}[/tex]

Now we can use property #2 to write this as:

[tex]Logx^{5}+Log(x+7)^{6}\\=Log((x^5)((x+7)^6)\\=Logx^{5}(x+7)^{6}[/tex]

We see that answer choice D is right.

Answer:

• changing an interior angle to a reflex angle

Step-by-step explanation:

In order for the outline of the polygon to have a pair of sides that is concave (pointed inward, rather than outward), the corresponding interior angle must be a reflex angle. (It must measure more than 180°.) Draw one; you'll see.

The slant height of a cone with a radius of 3 inches and a surface area of 16.8π square inches is 2.6 inches.

In order to find the slant height of a cone, we need to understand the formula for calculating the surface area of a cone. The formula is πrs + πr². The given surface area is 16.8π and the radius is 3 in. This area consists of the area of the base (which is a circle of radius 3 in, hence area πr² = π(3)² = 9π) and the area of the side, which is πr times the slant height (s).

So, we subtract the base area from the total area to isolate the side area: 16.8π - 9π = 7.8π. This is equal to πrs, so we can set up the equation: 7.8π = 3πs (we replace 'r' with its given value 3). Solving for 's', we divide both sides of the equation by 3π, getting slant height 's' = 7.8π / 3π, which simplifies to 2.6 inches.

Answer: any number

Step-by-step explanation: 3x+2y=6, 2y=6-3x, we want y by itself, so divide by 2 from both sides, y=3-1.5x, then we plug it into the equation,3x+2(3-1.5)=6, then solve. 3x+6-3x=6, 3x-3x=0,so 6=6, y could be any possible answer

The expression for y in terms of x is y = 3 - (3/2)x the linear equation 3x+2y=6 .

To express y in terms of x using the linear equation 3x + 2y = 6, we need to isolate y on one side of the equation.

Step 1: Move the 3x term to the other side of the equation.

Subtract 3x from both sides:

3x + 2y - 3x = 6 - 3x

2y = 6 - 3x

Step 2: Now, to solve for y, divide both sides by 2:

y = (6 - 3x) / 2

Step 3: We can further simplify the equation:

y = 6/2 - (3x/2)

y = 3 - (3/2)x

So, the expression for y in terms of x is y = 3 - (3/2)x.

Answer:

45, 60, 75

Step-by-step explanation:

The ratio of the angles are 6:8:10

Multiply by x to get the angle measures

6x, 8x,10x

We know the sum of the angles is 180 for a triangle

6x+8x+10x = 180

Combine like terms

24x = 180

Divide each side by 24

24x/24 = 180/24

x =7.5

Each angle is

6x = 6(7.5) =45

8x = 8(7.5) =60

10x = 10*7.5 = 75

The measures of the angles of the given triangle are 54 degrees, 72 degrees, and 90 degrees.

To find the measures of the angles of a triangle whose angles have measures in the ratio 6:8:10, we can use the fact that the sum of the angles in a triangle is always 180 degrees. Since the ratio of the angles is 6:8:10, we can set up the equation 6x + 8x + 10x = 180, where x is a common factor. Solving this equation, we find that x = 9. Therefore, the measures of the angles are 6x = 54 degrees, 8x = 72 degrees, and 10x = 90 degrees.

the weight of 200 quarters is 40 ounces.

The question asks to find the weight in ounces, w, of 200 quarters, given that a roll of 40 quarters weighs 8 ounces. To solve this problem, we can set up a proportion which is a statement that two ratios are equal. Since we know the weight of 40 quarters, we can compare this to the weight of 200 quarters. The proportion can be set up as follows:

40 quarters / 8 ounces = 200 quarters / w ounces

To find w, simply cross-multiply and divide:

Therefore, the weight of 200 quarters is 40 ounces.

The 21 consonants are :

b c d f g h j k l m n p q r s t v w x y z

The 5 vowels are :

a e i o u

Now, to arrange the consonants there are 21! ways.

Now the vowels can be arranged in 22 ways because one vowel can be placed before 'b' and one after 'z' also.

It can be shown like this : (V represents vowels)

V b V c V d V f .......................

Therefor the ways to put vowels will be : [tex]22P5[/tex]

The complete order to place consonants without repeating vowels becomes: [tex]22P5*21![/tex]

There are 22! x 6! x 5! ways to arrange the 26 letters of the alphabet so that no pair of vowels appear consecutively.

In order to arrange the 26 letters of the alphabet so that no pair of vowels appear consecutively, we can consider the vowels as a single block that needs to be placed in between the consonants. Firstly, let's count the number of ways to arrange the consonants C (21 consonants + 1 y) and the block of vowels V (5 vowels) as separate entities. This can be done in 22! x 6! ways. However, we need to consider that within the V block, the vowels can be rearranged in 5! ways. Therefore, the total number of arrangements is 22! x 6! x 5!.

Answer:

y = 1/3 x + 4

Step-by-step explanation:

The slopes of perpendicular lines are negative reciprocals. The given line is

y = -3x + 7

which is already in the slope-intercept form, y = mx + b, where m is the slope.

The slope of the given line is -3.

The slope of the perpendicular is the negative reciprocal of -3 which is 1/3.

The line we are looking for has an equation of the form

y = 1/3x + b

We need to find b. We use the x- and y-coordinates of the given point as x and y in the equation above, and we solve for b.

y = 1/3x + b

5 = (1/3)(3) + b

5 = 1 + b

4 = b

Now that we know that b = 4, we replace b with 4 in the equation

y = 1/3x + b to get the answer.

Answer: y = 1/3 x + 4

The equation of the line that is perpendicular to y=-3x+7 and passes through the point (3,5) is y = 1/3x + 4.

To find an equation of the line that is perpendicular to the line represented by the equation y = -3x + 7 and also passes through the point (3, 5), we must first find the slope of this new line. In mathematics, the perpendicular line's slope is the negative reciprocal of the original line's slope. Here, the slope of the original line is -3, so our new line's slope will be 1/3. Now we can use the point slope form to find the equation of the line:

y - y1 = m(x - x1)

Substituting our values, it becomes y - 5 = 1/3(x - 3), which simplifies to y = 1/3x + 4. So, the equation of the line is y = 1/3x + 4.

Answer: (1,2)

Step-by-step explanation:

You must:

- Multiply the first equation by 3.

- Add both equations.

- Solve for the variable left. In this case will be x.

Then:

[tex]\left \{ {{39x +3y = 45} \atop {-9x - 3y = -15}} \right.\\------\\ 30x=30\\x=1[/tex]

Substitute x=1 into any of the original equtions and solve for y:

[tex]13(1)+y=15\\y=2[/tex]

The solution is: (1,2)

Answer:

The solution of the system of equation is (1 , 2)

Step-by-step explanation:

The system of equation is:

* 13x + y = 15 ⇒ (1)

* -9x - 3y = -15 ⇒ (2)

- By using elimination ⇒ we must make on of the

 two variables in the two equations has the same value

 with different sign

- So we will multiply equation (1) by 3 to eliminate y

∴ 3(13x) + 3(y) = 3(15)

∴ 39x + 3y = 45 ⇒ (3)

- Now add (2) and (3)

∴ 39x + -9x = 45 + -15

∴ 30x = 30 ⇒ ÷ 30 both sides

∴ x = 1

- Substitute the value of x in equation (1) or (2)

- Lets use (1)

∴ 13(1) + y = 15

∴ 13 + y = 15 ⇒ subtract 13 from both sides

∴ y = 15 - 13  

∴ y = 2

∴ The solution of the system of equation is (1 , 2)

Answer:

The frequency = 5/2π

Step-by-step explanation:

* Lets revise some facts about the trigonometry function

- If the function is f(x) = A sin (B x + C) + D  

* A is the amplitude  

- The amplitude is the height from highest to lowest points and  

 divide the answer by 2  

* The period is 2π/B  

- The period is the distance from one peak to the next peak

- Period and Frequency are related where frequency = 1/period

* C is the horizontal shift  

- The horizontal shift is how far the function is shifted to left  

 (C is positive) or to right (C is negative) from the original position.  

* D is the vertical shift  

- The vertical shift is how far the function is shifted vertically up

  (D is positive) or down (D is negative) from the original position.  

* Lets solve the problem

∵ f(x) = 3 cos (5x) + 2

∵ f(x) = A sin (B x + C) + D  

∴ A = 3 , B = 5 , C = 0 , D = 2

∵ The period = 2π/B

∴ The period = 2π/5

∵ The frequency = 1/period

∴ The frequency = 1/(2π/5) ⇒ multiply up and down by 5

∴ The frequency = 5/2π

The frequency of the function f(x) = 3cos(5x) + 2 is 5/2π, represented as 5 cycles per unit interval on the x-axis.

The frequency of the function f(x) = 3cos(5x) + 2 is determined by the coefficient of x inside the cosine function. In this case, the coefficient is 5, which represents 5 cycles per unit interval on the x-axis. The standard form for a cosine function's frequency is given when the function is written as cos(2πft), with f representing the frequency. To match this form, we can rewrite the function as cos(2π(5/2π)x), making it clear that f = 5/2π cycles per unit interval, which is the frequency.

In simplest fraction form, the frequency of the function f(x) is 5/2π.

One solution.  It is (2, 1)

Step-by-step explanation:

Clear out all fractions right away by multiplying all terms by 10.  Then:

0.3x − 0.4y = 0.2

−0.2x + 0.5y = 0.1

becomes

3x - 4y = 2

-(2x + 5y = 1)

Multiply the first row by 2 and the second row by 3, which produces:

  6x - 8y = 4

 -6x +15y =  3

Combining like terms results in:         7y = 7.  Then y = 1.

Now subst. 1 for y in the first equation, to calculate x:

3x - 4(1) = 2

3x          = 2 + 4  = 6.  Then x = 2.

The solution is (2, 1).  There is ONLY ONE SOLUTION.

Answer:

y = 7   x = -11/3

Step-by-step explanation:

3x + 4y = 17

- (3x + 2y = 3)

Distribute the minus sign  and add together

3x + 4y = 17

- 3x - 2y = -3

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

2y    = 14

Divide by 2

2y/2 = 14/2

y = 7

Now find x

3x + 4y = 17

3x +4(7) = 17

3x +28 = 17

Subtract 28 from each side

3x+28 -28 = 17 -28

3x = -11

Divide each side by 3

3x/3 = -11/3

x = -11/3
