The correct answer would be option C.
Step-by-step explanation:
Since he gives the dog 3 liters of water and 500 grams of food a day we know that on the fifth day the dog will have gotten 15 liters of water and 2,500 grams of food.
The required coordinate will be (15, 2,500)
Given that the coordinates of the point at (3,500) represent the first day on a coordinate grid if Julie uses a pattern to plot 6 more points, the pattern used can be geometric in nature.We can scale the coordinate point up by five units since we need to get the significance of the fifth point Julie plots.Hence the required coordinate will be (15, 2,500) which is interpreted as the fifth day, Julie gave Banjo 15 liters of water and 2,500 grams of food.

The length of a rectangle is 7 m less than three times the width, and the area of a rectangle is 66 m^2. find the dimensions of the rectangle.
Answer:
length =11m
width =6m
Step-by-step explanation:
let the w = x
L = 3x-7
area =L*w
66 = (3x-7)*x
66 = [tex]3x^{2} -7x[/tex]
[tex]3x^{2} -7x-66=0[/tex]
[tex]3x^{2} -18x+11x-66=0[/tex]
3x(x-6)+11(x-6)=0
(3x+11)(x-6)=0
x-6=0
x=6
recall,
L = 3x-7 =3*6-7=11
Which of the following are equivalent ratios?
A: 12 : 16
B: 3 : 5
C: 2 : 3
D: 6 : 8
The equivalent ratios are A and D.
Here's an explanation:
When you look at D, you see that 12 is a multiple of 6, and 16 is a multiple of 8. So you know that it looks like they're equivalent. Then you test it out, 12/2=6. 16/2=8. so 12:16 = 6:8. Eyeballing it first can save time sometimes.
Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros. -1, 2, 3
Answer:
f(x) = x³ - 4x² + x + 6
Step-by-step explanation:
The polynomial function f has zeros at -1, 2, and 3.
So, the least degree of the polynomial will be 3{As it has three roots}.
Then, if the function is of x variable then (x + 1), (x - 2) and (x - 3) will be the factors of the polynomial.
Therefore, we can write
f(x) = (x + 1)(x - 2)(x - 3)
⇒ f(x) = (x + 1)(x² - 5x + 6)
⇒ f(x) = x³ - 5x² + 6x + x² - 5x + 6
⇒ f(x) = x³ - 4x² + x + 6
Hence, this is the polynomial with least degree having rational coefficients and with leading coefficient of 1 and the zeroes -1, 2, 3. (Answer)
20 millimeters long with an area of (20x-200) square millimeters. Write an expression that represents the perimeter (in millimeters) of the octopus pupil.
Answer:
Perimeter = (20 + 2x) mm.
Step-by-step explanation:
The octopus pupil has length 20 mm and the expression for its area is given by (20x - 200) square mm.
If the width of the octopus pupil is w, then 20w = 20x - 200
⇒ w = (x - 10) mm.
Therefore, the expression for its perimeter is 2(Length + Width) = 2 ( 20 + x - 10) = 2( 10 + x) = (20 + 2x) mm. (Answer)
The expression that represents the perimeter of the octopus pupil is 20 millimeters.
Explanation:To find the expression that represents the perimeter of the octopus pupil, you need to know the length and area of the pupil. The length is given as 20 millimeters, and the area is represented by the expression (20x-200) square millimeters. The perimeter of a shape is the sum of all its side lengths.
So, for the octopus pupil, the perimeter can be found by adding up the lengths of all its sides. Since the shape is not specified, we'll assume it's a regular shape with all sides equal in length.
To find the expression for the perimeter, we need to know the number of sides. If we assume it has n sides, then each side has a length of 20/n millimeters. Therefore, the perimeter expression would be 20/n multiplied by n, which simplifies to 20 millimeters.

OPTION A and OPTION C
Step-by-step explanation:
OPTION A:
[tex]$ \frac{1}{5}x - 10 $[/tex] and [tex]$ \frac{1}{5}(x - 50) $[/tex]
Consider [tex]$ \frac{1}{5}(x - 50) = \frac{x}{5} - \frac{50}{5} $[/tex]
This is equal to [tex]$ \frac{1}{5}x - 10 $[/tex].
This is exactly the first expression. So, we say both expressions are equivalent.
OPTION B:
[tex]$ \frac{1}{3} x - 6 $[/tex] and [tex]$ - \frac{1}{3}(3x + 18) $[/tex]
Distributing [tex]$ -\frac{1}{3} $[/tex] to [tex]$ (3x + 18) $[/tex] we get:
[tex]$ \frac{-x}{3} + \frac{-18}{3} $[/tex]
⇒ [tex]$ -x - 6[/tex]
This is not equivalent to the first expression.
OPTION C:
[tex]$ \frac{1}{2}x + 8 $[/tex] and [tex]$ \frac{1}{2}(x + 16) $[/tex]
[tex]$ \frac{1}{2}(x + 16) = \frac{x}{2} + \frac{16}{2} $[/tex]
[tex]$ \implies \frac{1}{2}x + 8 $[/tex]
This is exactly the first expression. So, we say the expressions are equal.
We apply similar techniques to OPTION D and OPTION E. Note that the expressions are not equal in both the options.

Max adds 7 to a number the. Múltiples the sum by -4 the result is 3 times the same number write and since an equation to find the number n what is the number
Answer:
The number is -4.
Step-by-step explanation:
Let the number be n.
Given:
Max adds 7 to a number.
hence it is given as n+7
Multiply's the sum by -4 the result is 3 times the same number.
Hence the equation can be written as;
[tex]-4(n+7)=3n[/tex]
Now Solving the above equation to find value of n we get;
[tex]-4(n+7)=3n\\-4n-28=3n\\-4n-3n=28\\-7n=28\\n=\frac{28}{7}=-4[/tex]
The value of n is -4.
Now when we add 7 to number -4 we get answer as 3.
And when the sum is multiplied by -4 we get answer -12.
Also 3 times of number is equal to 3 multiplied by -4 we get answer as -12.
Hence when the sum is multiplied by -4 it is equal to 3 times of same number.
Hence from above we can say that the number is -4.
Final answer:
The number that satisfies Max's operation of adding 7 to a number and then multiplying by -4 to get 3 times the same number is -4.
Explanation:
Max adds 7 to a number n, then multiplies the sum by -4, and the result is 3 times the same number n. To find the number n, we first write down the equation that represents this situation:
-4(n + 7) = 3n
Next, we solve for n:
Distribute -4 inside the parenthesis: -4n - 28 = 3n
Move all n terms to one side: -4n - 3n = 28
Combine like terms: -7n = 28
Divide both sides by -7 to isolate n: n = -4
The number n that satisfies this equation is -4.

Sin(cosx) = 1 solve for x
Answer:
There is no solution for x.
Step-by-step explanation:
We are given that [tex]\sin (\cos x) = 1[/tex] and we have to solve for x.
Let us assume that [tex]\cos x = \theta[/tex] then [tex]\sin \theta = 1[/tex] ........ (1)
Now, we know that for any value of x the value of cos x lies between 1 to - 1.
Hence, [tex]1 \geq \cos x \geq - 1[/tex] for all x.
⇒ [tex]1 \geq \theta \geq - 1[/tex]
Now, for [tex]1 \geq \theta \geq - 1[/tex], the value of [tex]\sin \theta[/tex] can never be equal to 1.
Hence, there is no solution for x. (Answer)

which graph represents a function?
Answer:
Graph C) represents a function.
Step-by-step explanation:
Graph C) is the only graph that passes the vertical line test, a way to determine if a graph is a function. All other graphs do not pass the vertical line test. The vertical line test states that if a vertical line drawn intersects the graph of the relation more than once, then the relation is a NOT a function.
The function is indeed a relationship that has only one outcome for each input value (x-value) and output value (y-value). As a result, all functions could be regarded as relationships. However, not all relations are functions because not all of them satisfy the criterion, so each unique input generates just one output.
The third option seems to be the only graph in the present situation that satisfies the vertical line test and determines if a graph is a function. The vertical line test fails on all other graphs. According to the diagonal line test, if a vertical line drawn over the graph of a relation meets it again, the relation is not a function.Therefore, the final answer is "Option C".
