Cafeteria ratio of Swiss cheese to cheddar cheese is 15:17.

Perry’s ratio of Swiss chess to cheddar cheese is 5:7.

Wrong ratio because 5 * 3 = 15 but 7 * 3 does not equal 17.

For this case we have that by definition, it is known as proportion to the relationship of equality that exists between two reasons, that is, between two comparisons. That is: if [tex]\frac {a} {b}[/tex]is a ratio, then the equality [tex]\frac {a} {b} = \frac {c} {d}[/tex] will be a proportion.

Then, 15 cups of Swiss cheese for every 17 cheddar:

1[tex]5:17\\\frac {15} {17}[/tex]

We want to verify the proportion:

[tex]15:17 :: 5: 7\\\frac {15} {17} = \frac {5} {7}\\7 * 15 = 5 * 17[/tex]

Equality is not met!

The answer is logarithmic

Answer:

Logarithmic .

Step-by-step explanation:

When we evaluate the logarithmic expression then we prepared to work

with logarithmic function

If , I want to solve the logarithmic expression then first we should  know about the logarithmic theorem rules .

If ,I don't know about the logarithmic rules then we can't evaluate the logarithmic expression.

So , first we should do practice with logarithmic function and we should know  how to use of logarithmic rules during evaluating the logarithmic expression .

Logarithmic rules :

[tex]Log \frac{m}{n}= log m - log n[/tex]

[tex]log m\times n= log m+ log n[/tex]

[tex]log a^b= bloga[/tex]

For example ; we have [tex]log\frac{3}{4}[/tex]

Therefore, by using logarithmic rule then we get

[tex]log\frac{3}{4} = log 3- log 4[/tex]

Therefore, if i want to evaluate the logarithmic expresssion then  i will be prepared to work with logarithmic function .

I think the rule might be x-9

Answer:

14

Step-by-step explanation:

Distance of the pathway around a park = 4 1/5 miles

Distances between lamppost = 3/20 miles

Numbers of 3/10 intervals

= 4 1/5 ÷ 3/10

= 21/5 x 10/3

= 14

Number of lamp posts = 14

28 because the number of spots in the pathway where the lampposts will be placed is 1/5 divided by 3/10=14. since each spot will have 2 lampposts, there will be 14*2=28 lampposts in all.

hope this helped!!!!!!!!!!!!!!!!!!!!!!!!

Answer:

Final answer is [tex]y=3x-13[/tex].

Step-by-step explanation:

Given that slope of the line is m=3

Plug the given point (4,-1) and the slope m=3 into point sloep formula:

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-(-1)=3\left(x-4\right)[/tex]

[tex]y+1=3\left(x-4\right)[/tex]

[tex]y+1=3x-12[/tex]

[tex]y=3x-12-1[/tex]

[tex]y=3x-13[/tex]

Which looks like slope intercept form of line y=mx+b

Hence final answer is [tex]y=3x-13[/tex].

The answer is:

The equation in slope-intercept form is:

[tex]y=3x-13[/tex]

To solve the problem and find equation in slope-intercept form of the line, we need to use the following formula:

[tex]y=mx+b[/tex]

We are given the slope of the line, so, rewriting we have:

[tex]y=3x+b[/tex]

Then, to find "b" we need to substitute the given point into the equation, so, substituting we have:

[tex]y=mx+b[/tex]

[tex]-1=3*(4)+b[/tex]

[tex]-1=12+b[/tex]

[tex]b=-1-12=-13[/tex]

Therefore, writing the equation of the line, we have:

[tex]y=3x-13[/tex]

Have a nice day!

Answer:

see below

Step-by-step explanation:

The function is only defined for x < 1, and is undefined for x=1 or more. Thus the graph stops at x=1, with an open circle indicating the function is not defined there.

Answer:

The required graph is shown in figure 1.

Step-by-step explanation:

Consider the provided function f(x)=x if x<1

Here the sign of inequality is x<1.

That means the value of x can be anything less then 1.

Note the sign "<" indicates that the value x is strictly less than 1 also it is not equal to 1.

For x=1 the function is not defined.

For the inequity "<" and ">" we use an open dot or open circle which shows that the value is not included.

Now draw the table and substitute some value of x as shown.

Substitute x=0 in the provided equation.

f(x)=0

For x=0 the value of f(x) is also 0.

Substitute x=-1

f(x)=-1

For x=-1 the value of f(x) is also -1.

Substitute x=-2

f(x)=-2

For x=-2 the value of f(x) is also -2.

The required table is shown below:

x   0  -1  -2

f(x) 0  -1  -2

Now plot the above points and join them.

The required graph is shown in figure 1.

Answer:

5; you add the two legs for the hypotenuse

Step-by-step explanation:

The length of the hypotenuse is 5 feet.

The hypotenuse is the opposite side of the right angle in the triangle. It’s also the longest side of the triangle.

The Pythagorean Theorem helps us calculate the hypotenuse of a right triangle if we know the sides of the triangle.

Here, a = 3 feet.

         b = 2 feet.

    Then hypotenuse will be = (√3 + √2) feet

                        = 5 feet.

The answer is 5 feet.

ANSWER

[tex]y = 5 \sin( \frac{6}{5} x - \pi)-4 [/tex]

EXPLANATION

The given function is

[tex]y = 5 \cos( \frac{3}{5} x - \pi) + 4[/tex]

The period of this function can be determined using the formula:

[tex]T= \frac{2\pi}{ |b| } [/tex]

.

The period is

[tex]T= \frac{2\pi}{ \frac{3}{5} } = \frac{10\pi}{3} [/tex]

Half the period of this function is:

[tex] \frac{ \frac{10\pi}{3} }{2} = \frac{5\pi}{3} [/tex]

The function which has this period is

[tex]y = 5 \sin( \frac{6}{5} x - \pi) -4[/tex]

The first choice is correct.

Answer: y=31

Step-by-step explanation

If x=5 and y=6x+1, you plug in 5 for x in the equation y=6x+1.

This would cause it to be y=6(5)+1.

Then you multiply 6*5, which equals 30. thatll turn into y=30+1

30+1=31, so y=31

Answer:

Y = 31

Step-by-step explanation:

Replace x with 5

BC = 144 units

Step-by-step explanation:

It is given a line segment BC.

D is the point on the line segment.

To find the length of BC

BC = 8x

CD = 3x + 8  and BD = 4x + 10

BC = CD + BD

8x = 3x + 8 + 4x + 10

8x = 7x + 18

x = 18

BC = 8x = 8 * 18 = 144 units

Therefore the length of segment BC = 144 units

Segment BC is 144 units

Answer:C 30

Step-by-step explanation: They all divide evenly when divided by 30.

Answer:

x < - 1

Step-by-step explanation:

Given

5x + 8 < 3(x + 2) ← distribute

5x + 8 < 3x + 6 ( subtract 3x from both sides )

2x + 8 < 6 ( subtract 8 from both sides )

2x < - 2 ( divide both sides by 2 )

x < - 1

The inequality 5x + 8 < 3(x + 2) simplifies to x < -1.

To solve the inequality 5x + 8 < 3(x + 2), we must simplify and isolate the variable x. We start by distributing the 3 on the right side:

5x + 8 < 3x + 6

Next, we'll subtract 3x from both sides to get:

2x + 8 < 6

Now subtract 8 from both sides to isolate the term with x:

2x < -2

Finally, we divide both sides by 2:

x < -1

The solution to the inequality is all x-values that are less than -1.

The total cost of 1 pair of pants and 1 shirt is $18 . If s represents the cost of 1 shirt, which equation could you use to find .

For this case we propose a system of equations:

p: Variable representing the cost of a pair of pants

s: Variable representing the cost of a shirt

A pair of pants costs twice as much as a shirt, means:

[tex]p = 2s[/tex]

The total cost of 1 pair of pants and 1 shirt is $ 18:

[tex]p + s = 18[/tex]

We substitute the first equation in the second:

[tex]2s + s = 18\\3s = 18\\s = \frac {18} {3}\\s = 6[/tex]

Step-by-step explanation:

Answer:

the function g(X) is a translation of [tex]f(x) = \sqrt{x}[/tex]

the range is {y|y≥-1}

the function g(x) can be translated 3 units right and 1 unit up to get the function [tex]f(x) = \sqrt{x}[/tex]

Step-by-step explanation:

Given the graph of a function g(x)

g(x) looks like a square root function

So parent function is [tex]f(x) = \sqrt{x}[/tex]

the function g(X) is a translation of [tex]f(x) = \sqrt{x}[/tex]

the domain is {x| x ≥ -3}

the range is {y|y≥-1}

The parent function [tex]f(x) = \sqrt{x}[/tex] starts at (0,0)

so g(x) is translated 3 units left and 1 unit down

the function g(x) can be translated 3 units right and 1 unit up to get the function [tex]f(x) = \sqrt{x}[/tex]

Answer:

The correct options are 1, 3 and 5.

Step-by-step explanation:

The given function is a continuous increasing curve which is increasing at decreasing rate. It means it is the graph of a radical function.

Parent radical function is

[tex]f(x)=\sqrt{x}[/tex]

It means function g(x) is the translation of function [tex]f(x)=\sqrt{x}[/tex]. Option 1 is correct.

Domain is the set of input values.

Function is defined for all x ≥ -3.

Domain = { x |  x ≥ -3 }

Option 2 is incorrect.

Range is the set of output values.

The values of the function are always greater than or equal to -1.

Range = { y |  y ≥ -1 }

Option 3 is correct.

The graph of parent function [tex]f(x)=\sqrt{x}[/tex] shifts 3 units left and 1 unit down to get the graph of g(x). So the function g(x) is defined as

[tex]f(x)=\sqrt{x+3}-1[/tex]

Option 4 is incorrect.

The function g(x) can be translated right 3 units and up 1 unit to create the function [tex]f(x)=\sqrt{x}[/tex].

Option 5 is correct.

Cos(90)= 0.00

It is only zero

The value of cosine  90°. or cos  90° is 0.

Trigonometric ratios are the ratios of the length of sides of a triangle.

In trigonometry, there are six trigonometric ratios, namely, sine, cosine, tangent, secant, cosecant, and cotangent.

We know that,

According to the trigonometric table the value of cos 90° is 0.

i.e.,  cos 90°.

This is because there is no horizontal component of the angle: The horizontal component of the angle is 0, so, the cosine of 90° is 0.

In other words,

the cosine of an angle tells the size of the adjacent side of a right triangle compared to the hypotenuse. Look at the unit circle to see why the adjacent side (the x axis) has a width of 0 when the angle between the initial arm and the terminal arm is a right angle.

Thus, value of cos 90 is 0.

f(x) = x³ – 2x² – x + 2

 0 = x3 – 2x2 – x + 2

 (x-2)(x-1)(x+1)=0

 x1=-1

 x2=1

 x3=2

For this case we must follow the steps below:

We factor the polynomial, starting by factoring the maximum common denominator of each group:

[tex]x ^ 2 (x-2) - (x-2)[/tex]

We factor the maximum common denominator[tex](x-2):[/tex]

[tex](x-2) (x ^ 2-1)[/tex]

Now, by definition of perfect squares we have:

[tex]a ^ 2-b ^ 2 = (a + b) (a-b)[/tex]

Where:

[tex]a = x\\b = 1[/tex]

Now, we can rewrite the polynomial as:

[tex](x-2) (x + 1) (x-1)[/tex]

To find the roots we equate to 0:

[tex](x-2) (x + 1) (x-1) = 0[/tex]

So, the roots are:

[tex]x_ {1} = 2\\x_ {2} = - 1\\x_ {3} = 1[/tex]

Answer:

[tex]x_ {1} = 2\\x_ {2} = - 1\\x_ {3} = 1[/tex]
