cheryl bought 3.4 pounds of coffee thay cost $6.95 per pound. How much did she spend on coffee?

Answer:

f(1) = 1

Step-by-step explanation:

A function can have only one value of y for a given value of x.

Thus, if f(1) = 5, we cannot have f(1) = 1.

We can have f(2) =1 and f(5) = 5, because these are values of y for different values of x,

The first diagram below is the graph of a function, because there is only value of y that corresponds to a given value of x.

The second diagram is not the graph of a function, because there are two values of y that correspond to a given value of x.

However, the top semicircle and the bottom semicircle separately are graphs of functions, because they each have only value of y that corresponds to a given value of x.

Final answer:

The statement that could not be true for a function f(x) where f(1) = 5 is any claim that f(x) takes a different value than 5 for any x within the domain [0, 20], where f(x) is described as a horizontal line. Therefore, if f(1) = 5, it must be true that f(x) = 5 for all x in [0, 20].

Explanation:

If f(x) is a function and f(1) = 5, then it indicates that when we input 1 into the function f, we get the output of 5. The question asks which statements could not be true based on this piece of information and additional details regarding the nature of function f. The provided information suggests that the graph of f(x) is horizontal for 0 ≤ x ≤ 20, which means the output value of f(x) is the same for any input value x within that domain.

Likewise, we can determine some possible characteristics of f(x) based on the nature of continuous functions. Adding a constant to f does not affect the derivative, so despite the value of f at x = 1 being 5, we cannot deduce the exact form of f but can infer its behavior around that point. It is essential to note that when a function is defined as a continuous horizontal line within a certain domain, its value is constant across that domain. As a result, if f(1) = 5 for the function f(x) = a horizontal line on the interval [0, 20], it implies that f(x) must be 5 for all x in that interval.

Therefore, any statement that implies the function has a different value than 5 for any x in [0, 20] cannot be true. For instance, if there were a claim that f(2) ≠ 5 or that f(x) is not defined for some x within the interval where it is supposed to be a horizontal line, such a statement would be false given the function's described behavior.

The sum of the interior triangles in a triangle is 180, so if we add all the angle measures together, we should get 180. Therefore, we can make an equation like this,

[tex]110-2x+x+50+5x-40=180[/tex]

Simplify this.

[tex]4x+120=180[/tex]

[tex]4x=60[/tex]

[tex]x=15[/tex]

Now we can find each angle measure.

[tex]110-2x[/tex]

[tex]110-2(15)[/tex]

[tex]110-30[/tex]

[tex]80[/tex]

[tex]x+50[/tex]

[tex]15+50[/tex]

[tex]65[/tex]

[tex]5x-40[/tex]

[tex]5(15)-40[/tex]

[tex]75-40[/tex]

[tex]35[/tex]

So the angle labeled [tex]110-2x[/tex] is the largest angle in the triangle.

Answer:

x=15

biggest angle is 110-2x

Step-by-step explanation:

If the functions f(x) = 7 + 4x and g(x) =1/2x then the value of  (f/g)(5) is 270, option D is correct.

A relation is a function if it has only One y-value for each x-value.

The given functions are f(x) = 7 + 4x and g(x) =1/2x

We have to find the value of (f/g)(5)

We know that from properties of functions

(f/g)(a)=f(a)/g(a)

So let us find f(5) and g(5)

f(5)=27

g(5)=1/10

(f/g)(5)=27/(1/10)

=27×10

=270

Hence, if the functions f(x) = 7 + 4x and g(x) =1/2x then the value of  (f/g)(5) is 270, option D is correct.

2. $ 34.21

Step-by-step explanation:

Let the price of XYZ inc's share to be = $ x

On Monday, the price drops by $ 0.02 = $ x- $ 0.02 = $ (x-0.02)

New price of shares on Monday is = $ (x- 0.02)

Answer:

x=6

Step-by-step explanation:

2x+4=16

-4       -4

2x+4-4=16-4

2x=12

/2   /2

2x/2=12/2

x=6

Answer:

x=6

Step-by-step explanation:

2x+4 = 16

Subtract 4 on each side

2x+4-4 = 16-4

2x = 12

Divide each side by 2

2x/2 = 12/2

x = 6

Answer:

0.500.

Step-by-step explanation:

f(x) = 1/16 ^ 1/4

Now 16 ^1/4 = ⁴√16

= 2

so f(x) = 1/2

= 0.500.

First you must bring 6 to the other side of the equation so it equals zero. To do this subtract 6 to both sides

20p^2+33p+16 - 6=6​ - 6

20p^2+33p+10=0

Use the quadratic equation to solve this (image of the quadratic equation is below)

Remember that quadratic functions are set up like so:

[tex]ax^{2} +bx +c = 0[/tex]

That means that in this equation...

a = 20

b = 33

c = 10

^^^Plug these numbers into the quadratic equation and solve...

Answer:

36° and 54°

Step-by-step explanation:

We are given that one of the small angles of a right angled triangle is 18 less than twice the measure of the other small angle.

We are to find the measure of both angles.

Assuming [tex]x[/tex] to be the other small angle, 8 less than twice the measure of the other small angle = [tex]2x-18[/tex].

Summing all three angles up ti get:

[tex]x+(2x-18)+90=180[/tex]

[tex]3x=180-90+18[/tex]

[tex]3x=108[/tex]

[tex]x=\frac{108}{3}[/tex]

x = 36°

So other angle will be [tex]2(36)-18=[/tex] 54°.

Answer:

36° and 54°

Step-by-step explanation:

let x be one of the smaller angles, then the other smaller angle is 2x - 18 ( 18 less than twice the other )

Since it is a right triangle then the sum of the 2 smaller angles equals 90, so

x + 2x - 18 = 90

3x - 18 = 90 ( add 18 to both sides )

3x = 108 ( divide both sides by 3 )

x = 36

One angle = 36°

the other angle = (2 × 36) - 18 = 72 = 18 = 54°

ANSWER

[tex]w = 50.5[/tex]

[tex]l = 88.5[/tex]

EXPLANATION

The basketball court has a rectangular shape.

The perimeter of this court is calculated using the formula

[tex]P=2(l + w)[/tex]

It is given that,the court has a perimeter of 278ft. Let the width of the court be 'w' units, then the length is "w+38"

The perimeter then becomes:

[tex]2(w + 38+ w) = 278[/tex]

[tex]2w + 38= 139[/tex]

[tex]2w = 139 - 38[/tex]

[tex]2w = 101[/tex]

[tex]w = 50.5[/tex]

[tex]l = 50.5 + 38 = 88.5[/tex]

Check

[tex]P = 2(88.5 + 50.5)[/tex]

[tex]P = 2(139) = 278[/tex]

x+3y=6

To graph, you need to create a table for values of x with corresponding values of y that satisfy the equation

Sample points that solve the equation could be;

(-3,3),(3,1) and (-9,5)

From the graph attached, the three points are;

well, the only difference from a parallelogram that is a square or a rectangle and one that isn't, is that the interior angles are 90° in the square and rectangle, however for other ones, like the one in the picture below, they are not 90°.

however, getting to any vertex, is just a matter of moving horizontally and vertically the same distances, as you see those arrows on the picture, since both pair of sides are parallel, one moves the same distance horizontall and vertically to get to the next vertex, so on that, is the same as for a square or rectangle as well.

is only different in that you're not moving alongside the segment, in a rectangle or a square, the lines are only vertical or horizontal, so you simply move straight to get the next vertex, on other parallelograms like the one below, you do move the same but is not alongside the segments.

A) No B) The relation f(8) C) x = 3

Step-by-step explanation:

A) In mathematics, a function is a relation between sets that associates to every element of a first set exactly one element of the second set. Typical examples are functions from integers to integers or from the real numbers to real numbers.

B) Lets name the upper table outputs "g(x)", so

[tex]g(8) = 8 \: \: and \: \: f(8) = 8 \times 8 - 5 = 64 - 5 = 59[/tex]

[tex]\: 59 > 8 \: \: therefore \: \: f(8) > g(8)[/tex]

C)

[tex]f(x) = 19 \: \: and \: \: f(x) = 8x - 5 \\ 8x - 5 = 19 \\ 8x = 19 + 5 \\ 8x = 24 \\ x = 24 \div 8 \\ x = 3[/tex]

D Subtraction Property of Equality

Step-by-step explanation:

Whenever we subtract the same number of expression from both sides of the equation, the equality remains the same.

Reason A.  - Consecutive Interior Angles

Reason B.  - Substitution Property of Equality

Reason C.  - Subtraction Property of Equality

The Property of equality that accurately completes Reason B in the figure and flowchart proof is the Addition Property of Equality (A).

The property of equality that accurately completes Reason B in the figure and flowchart proof is the Addition Property of Equality (A).

The Addition Property of Equality states that if you add the same number to both sides of an equation, the equality is still preserved. In other words, if A + B = B + A, you can add the same number to both sides to obtain A + B + C = B + A + C, where C is any number.

In the given figure and flowchart proof, the equation A + B = B + A represents the Addition Property of Equality, and by applying this property, we can conclude that Reason B should be completed with the Addition Property of Equality (A).
