What is the percent change in his water intake?
What is the original amount of water in this problem?
What is the change in David's water intake in this problem?
What is the percent change?
Is it increasing or decreasing?
The original amount of water is 15 cups.
The change in David's water intake is 3 cups.
The percent change is 20 %. This is a percent decrease.
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100.
Given that, David is tracking the amount of water he drinks each day.
On Thursday, he drinks 15 cups of water.
On Friday, he drinks 12 cups of water.
The percent change in his water intake = (12 - 15) / 15 × 100 = -20%
Where minus sign is showing a decrease in the water intake,
The original amount of water is 15 cups.
The change in David's water intake is (15-12) = 13 cups.
Hence, the answers are;
The original amount of water is 15 cups.
The change in David's water intake is 3 cups.
The percent change is 20 %. This is a percent decrease.

Step-by-step explanation:
A quadrilateral with vertices P (1,-1), Q(3,-7), R(-9,-11) and S (-11,-5) is a parallelogram. Select the correct statement to justify the diagonals of a parallelogram bisecct each other
The distances from the midpoint M to the vertices are all the same and equivalent to 5·√2, therefore, the diagonals of the quadrilateral bisect each other.
What is a diagonal of a quadrilateral?A diagonal is a line that joins the opposite corners of the quadrilateral.
The question is without the possible options for the response.
The vertices of the quadrilateral are;
P(1, -1), Q(3, -7), R(-9, -11), and S(-11, -5)
The midpoint of the side PR = ((-9 + 1)/2, (-11 + (-1))/2) = (-4, -6)
Midpoint of the diagonal SQ = ((3 + (-11))/2, (-7 - 5)/2) = (-4, -6)
Let M represent the point of intersection of the diagonals, we get;
PM = √((1 - (-4))² + (-1 - (-6))² = 5·√2
MR = √((-9 - (-4))² + (-11 - (-6))² = 5·√2
The length of PM = The length of MR, therefore, the diagonal SQ bisects PM
Similarly, we get;
SM = √((-9 - (-4))² + (-11 - (-6))²) = 5·√2
MQ = √((3 - (-4))² + (-7 - (-6))²) = 5·√2
The length PM = MR and the lengths SM = MQ, therefore, the diagonals bisect each other.

6. Emma's cake recipe requires three large eggs to make two dozen slices of cake. how many large eggs are needed to make 144 slices of cake? (A) 16 (B) 8 (C) 9 (D) 12(E) Other
(E) Other
To make 144 slices of cake, Emma will need 18 large eggs.
To solve this problem, we need to know how much 2 dozen is.
1 dozen = 122 dozen = 24So, for every 24 slices of cake, 3 eggs are needed.
To figure out how many slices of cake 1 egg can make, we can divide 24 by 3.
24 ÷ 3 = 83 ÷ 3 = 1Now, for every 8 slices of cake, 1 egg is needed.
Now, taking 144, we can divide that by 8 to get the number of eggs needed.
144 ÷ 8 = 18Therefore, 18 eggs will be needed to make 144 slices of cake.
The graph above is a graph of what function?
Answer:
The graph of the function is a parabolic function graph
Step-by-step explanation:
Formula for a parabolic function: ( x - h )² = 4p ( y - k )
where ( h , k ) is the vertex and ( h , k + p ) is the focus
y is the directrix and y = k – p
The equation of the parabola is also given by the equation
y = ax² + bx + c
where a , b , and c are the three coefficients and the parabola is uniquely identified
Given data ,
Let the graph be represented as A
Now , a parabola is a U-shaped curve that is drawn for a quadratic function, f(x) = ax² + bx + c.
The value of the graph increases and decreases in a format according to the quadratic equation.
So , the graph of the function goes downward when value of a < 0 and the graph of the function goes upward when the value of a > 0
The graph of the parabola is downward (or opens down), when the value of a is less than 0, a < 0. The graph of parabola is upward (or opens up) when the value of a is more than 0, a > 0
Therefore , the graph is a parabolic graph
Hence , The graph of the function is a parabolic function graph
A population of 60 foxe in a wildlife preerve triple in ize every 14 year. The function y = 60 • 3*. Where x i the number of 14-year period, model the population growth. How many foxe will there be after 42 year?
The population of foxes in the preserve after 42 years will be:
1620 foxes.
The function "y = 60 • 3^t" models the population growth of foxes in a wildlife preserve.
"y" represents the population size, "60" is the initial population size, "3" is the factor by which the population triples, and "t" is the number of 14-year periods that have passed.
In this case, we are told that 42 years have passed, so we can calculate the number of 14-year periods as "t = 42/14 = 3".
Substituting this value of "t" into the function, we get: So, t = 42/14 = 3
Substituting that into the function:
y = 60 • 3^ty = 60 • 3^3y = 60 • 27y = 1620So, after 42 years, the population of foxes in the preserve will have grown to 1620 foxes.
Complete Question:
"A population of 60 foxes in a wildlife preserve triples in size every 14 years. The function y = 60 • 3^x models the population growth, where x is the number of 14-year periods. How many foxes will there be after 42 years?"

Let a1 =,a2= and b=. For what value (s) of h is b in the plane spanned by a1 and a2?
When h=-17 is b in the plane spanned by a1 and a2.
For the plane spanned by a1 and a2, y is a linear combination of a1 and a2 if it is in the plane,
y = a a1 + b a2
where a and b are constants,
[4,1,h] = a[1,4,-2] + b[-2,-3,7]
[4,1,h] = [a - 2b,4a -3b,-2a+ 7b]
by the rules of vector addition and multiplication.
Vectors are equal if their components are equal:
4 = a - 2b
1 = 4a - 3b
h = -2a + 7b
solve for a and b from the first two equations so that we can find h,
b = -3
h = -17
We see that -2[1,4,-2] - 3[-2,-3,7] = [4,1,-17].
so ,the value of h=-17 is b in the plane spanned by a1 and a2.

two of the interior angles of a triangle are 45.5 degrees and 14.6 degrees. what is the third interior angle of the triangle?
The third interior angle of the triangle is 119.9 degrees
Triangle is a closed polygon consist of three sides, three angle or three segment.
Triangle has three angle which if we sum all of those three angle it will be 180 degrees.
Triangle can be divided into several type :
1. Equilateral triangle which all of the angle is equal ( 180 degrees / 3 = 60 degrees each )
2. Isosceles triangle which have two equal angle, and the third angle is different
3. Scalene triangle which all of the angle is different
From the question, we have data :
1. First Angle is 45.5 degrees
2. Second Angle is 14.6 degrees
For the Third angle, we just simply subtract 180 degrees with the first and second angle. So it will be :
Third Angle = 180 degrees - ( 45.5 degrees + 14.6 degrees )
= 180 degrees - 60.1 degrees
= 119.9 degrees

find the solution to the differential equation dydt=y2(4 t), y=8 when t=1.
The solution to the differential equation is ln |y| = 4t - 4.
The given differential equation can be written as ∆y/∆t = y2(4t). This is a first-order separable differential equation, which can be solved using the separation of variables method. To do this, we first isolate the dy/dt term on one side of the equation. We can then separate the two variables (t and y) by moving all terms with t to one side and all terms with y to the other side. This gives us ∆y/y2 = 4∆t. We can then integrate both sides to find the solution.
Integrating both sides with respect to y gives us the following:
ln |y| = 4t + C,
where C is an integration constant. We can use the boundary condition to solve for C. The boundary condition states that y=8 when t=1, so substituting this into the equation above gives us ln |8| = 4 + C. Solving for C gives us C=-4.
Therefore, the solution to the differential equation is ln |y| = 4t - 4. Rearranging this equation gives us y = e4t-4, which is the solution to the differential equation.

what two types of feet are prominent in these lines
In poetry, the two main types of feet are iambic and trochaic.
Iambic foot: An iambic foot consists of two syllables, with the first syllable being unstressed and the second syllable being stressed. This creates a rhythmic pattern of "da-DUM" that gives iambic meter its characteristic "rising" sound. Iambic meter is one of the most common types of meter in English poetry, and is often associated with a natural, conversational rhythm.
Trochaic foot: A trochaic foot consists of two syllables, with the first syllable being stressed and the second syllable being unstressed. This creates a rhythmic pattern of "DA-dum" that gives trochaic meter its characteristic "falling" sound. Trochaic meter is less common than iambic meter in English poetry, but is still used in a variety of forms and styles. It can create a sense of tension or urgency, and is often used in poetry that is meant to be dramatic or suspenseful.
It's important to note that these two types of feet are just two of many possible metrical patterns that can be found in poetry. However, they are two of the most basic and widely recognized, and a good starting point for understanding the rhythms and structures of poetic meter.

suppose that c→=a→−b→. under what circumstances is the length of c→ equal to the sum of the lengths a→ and b→ ?
The length of c→ is equal to the sum of the lengths of a→ and b→ when c→ is a perpendicular vector to both a→ and b→, meaning that c→ is at a right angle to both a→ and b→.
This is due to the fact that the length of a vector is equal to the length of the hypotenuse of a right triangle, which is the sum of the lengths of the other two sides (a→ and b→). When c→ is perpendicular to both a→ and b→, the right triangle formed by a→, b→, and c→ is a special type of right triangle called a Pythagorean triangle, in which the length of the hypotenuse (c→) is equal to the sum of the lengths of the other two sides (a→ and b→). Thus, the length of c→ is equal to the sum of the lengths of a→ and b→ when c→ is perpendicular to both a→ and b→.

What is the equation of a line that passes through (4,-1) and is parallel to
y = 1/4x +7?
PLEASE ANSWER ASAP THIS IS FOR MY FINAL
Answer:
The equation of a line in slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept. Since the line given in the question is parallel to y = 1/4x + 7, we know that the line has a slope of m = 1/4.
To find the equation of the line that passes through (4,-1), we can use the point-slope form of a linear equation, which is y - y1 = m(x - x1).
Therefore, the equation of the line passing through (4,-1) and parallel to y = 1/4x + 7 is:
y - (-1) = 1/4(x - 4)
y + 1 = 1/4x + 1
This is the equation of a line passing through (4,-1) and parallel to y = 1/4x + 7.

For (a), the value of x must be the 98th percentile of T22, which is the value of x such that 98% of the data points of T22 are less than or equal to x. For (b), the value of x must be the 85th percentile of T13, which is the value of x such that 85% of the data points of T13 are less than or equal to x. For (c), the value of x must be the 26th percentile of T26, which is the value of x such that 26% of the data points of T26 are less than or equal to x. For (d), the value of x must be the 97.5th percentile of T2, which is the value of x such that 97.5% of the data points of T2 are less than or equal to x. In order to find these values of x, one must first calculate the percentiles of the given variables. This can be done by sorting the data points in ascending order and then calculating the percentile of each data point. After the corresponding percentile of each data point has been calculated, the desired values of x can be determined by finding the data point whose percentile matches the desired value.
