Find the sum of 10(E)(i=3) 2i-9
The sum represented by the notation [tex]\sum\limits^{10}_{i=3} {2i - 9[/tex] is 32
How to determine the sum represented by the notation
From the question, we have the following parameters that can be used in our computation:
[tex]\sum\limits^{10}_{i=3} {2i - 9[/tex]
This means that we determine the value of the expression from i = 3 to i = 9 and then add them up
So, we have
2(3) - 9 = -3
2(4) - 9 = -1
2(5) - 9 = 1
2(6) - 9 = 3
2(7) - 9 = 5
2(8) - 9 = 7
2(9) - 9 = 9
2(10) - 9 = 11
Evaluate the sum
Sum = -3 - 1 + 1 + 3 + 5 + 7 + 9 + 11
Sum = 32
Hence, the sum represented by the notation is 32

Cheddar cheese cost 4.25 per pound. Which equation best represents y, the cost of x pound of cheddar cheese
Answer:
y = 4.25x
Step-by-step explanation:
Answer:
y = 4.25x
Step-by-step explanation:
Cheddar cheese cost 4.25 per pound . This means the cost of cheddar cheese is 4.25 for every pound in weight. Assuming we put a currency to the value we can say 1 pound of cheddar cheese is equals to 4.25 dollars($4.25). Mathematically, it can be represented as
4.25 is the cost for 1 pound of Cheddar cheese
Let the cost of the equation be y as required from the question.
y = cost of the cheddar cheese
x is the weight value in pounds of the Cheddar cheese.
The equation can be best represented as
y = 4.25x
In the equation above if the amount in pounds is 3 pound . the value will be inputted for x and the cost will be gotten which is y.

point A lies in plane B how many planes can be drawn perpendicular to plane B through point A
1) one
2)two
3) zero
4) infinite
Answer:
4
Step-by-step explanation:
Only one plane can be drawn perpendicular to plane B through point A in three-dimensional space. The correct answer is option 1) that is One.
The question at hand involves geometric concepts, specifically the relationship between planes and lines in three-dimensional space. If point A lies in plane B, then there can be one and only one plane drawn perpendicular to plane B through point A; this is because in three-dimensional space, a point defines a line and only one perpendicular plane can contain that line.
This principle is similar to how any three points not on a single straight line determine a plane and how two lines intersect at a single point or not at all. The perpendicular plane would form a 90-degree angle along every line in plane B that passes through point A.
The correct answer is option 1) that is One
what is the y intercept of the line y-14=6(x-2.5)
Answer:
The y intercept is -1
Step-by-step explanation:
y-14=6(x-2.5)
We need to get the equation in the form y = mx+b where b is the y intercept
Distribut the 6
y-14 = 6x -15
Add 14 to each side
y-14+14 = 6x-15+14
y = 6x-1
The y - intercept is -1
Answer:
(0, -1)
Step-by-step explanation:
y-14=6(x-2.5)
Distributive property:
y-14 = 6 * x - 6*2.5
y-14= 6x-15
Add 14 on each side:
y-14+14=6x-15+14
Simplify:
y=6x-1
In the form y=mx+b (slope-intercept form, as shown above), the y-intercept is (0, b). b is -1.

The diagram shows two parallel lines cut by two transversals. Which statement is NOT true?
A. Angle c is congruent to angle e.
B. The measures of angles a, d, and e sum to 180°.
C. Angles a, b, and c are the interior angles of a triangle.
D. Angle b is congruent to angle e.
Answer:
D
Step-by-step explanation:
A) True. Alternate interior angles are congruent so
[tex]\angle c\cong \angle e[/tex]
B) True. Considering the sum of these three angles is equal to a straight angle. Since ∠a+∠d supplementary to ∠e
[tex]\angle a+\angle e+\angle d=180[/tex]
C) True. Since the line segments form a triangle having a (black) line as triangle base.
D) False. ∠b is congruent to its corresponding angle, and ∠e is not its corresponding angle. The corresponding angle of ∠b is the angle vertex opposed to ∠d (not identified).
which is greater 23/44 or 33/64
Answer:
23/44 < 33/64
Step-by-step explanation:
if you don't want to get common denominators multiply the denominator of the second fraction by the numerator of the first (1,427) and the denominator of the first one to the numerator of the second (1,452) the bigger number is greater. 1,427 < 1,452
By converting both fractions into decimals (23/44 becomes 0.5227; 33/64 becomes 0.5156), it is clear that 23/44 is greater than 33/64.
Explanation:To compare which fraction, 23/44 or 33/64, is greater, you need to find a common denominator and then compare the numerators. The calculation can be simplified by converting these fractions into decimals. To do so, divide the numerator by the denominator. Therefore, 23/44 becomes 0.5227 and 33/64 becomes 0.5156. Therefore, 23/44 is greater than 33/64.

There are s s milligrams ( mg ) (mg) of vitamin C per milliliter of spinach, b mg bmg per milliliter of berries, and d mg dmg per milliliter of dressing. Which expressions can we use to describe how many milligrams of vitamin C are in the salad?
Answer:
X= (300 s + 200 b + 42 d )mg
Step-by-step explanation:
Amount of spinach=300 ml
Amount of berries =200 ml
amount of dressing = 42 ml
Vitamin C in one ml of spinach = s mg
Vitamin C in 300 ml of spinach = 300 s mg
Vitamin C in one ml of berries=b mg
Vitamin C in 200 ml of berries = 200 b mg
Vitamin C in one ml of dressing = d mg
Vitamin C in 42 ml of dressing = 42 d mg
Let total vitamin C be = x
Then
X= (300 s + 200 b + 42 d )mg

Point Q is the opposite of point P. Determind the location of point Q on the number line
Answer:
With a number line with two points opposite from each other on a number line, the middle of it is always going to be 0. Therefore, both points are the same distance away from 0 just in opposite directions. That means point Q is always going to equal the negative of point P. An example of this is if point p equals 5, point p equals -5.
This method only works when it is specifically stated that the two points are opposite from each other.

The location of Point Q on the number line is the opposite of the location of Point P. If Point P is at +a, then Point Q is at -a, and vice versa.
Explanation:In order to determine the location of Point Q, we first need to know the location of Point P on the number line. If we assume that point P is positive and located at +a, then Point Q, being the opposite of Point P, would be located at -a on the number line. Conversely, if Point P was negative and located at -a, the opposite, Point Q, would be on the +a location on the number line. The important thing to remember here is that opposite points on a number line are simply reflection of each other with respect to the origin (0).

Uhh it should be increasing linear but the (3,8) kinda threw it off
The rule for the first set of ordered pairs is y = 6x, representing a linear, increasing function.
The relationship between the number of college courses and time spent on homework is increasing and non-linear.
Explanation:The ordered pairs (1, 6), (2, 12), (3, 18), (4, 24), and (5, 30) show that for each value of x, y is always six times as much.
Thus, the rule that represents this function is y = 6x.
When you plot these points on a graph, the line will be straight, showing it's a linear function, and because y increases as x increases, it is an increasing function.
Looking at the other set of ordered pairs for the number of college courses versus the time spent on homework, we can see that as the number of courses increases, the time spent also increases, showing that the relationship is increasing.
However, the increase in time is not consistent (3, 6, 8, 12), which suggests the relationship is non-linear.
what is the midpoint of mn?
First off, the length of MN is 2√10, not 8. This is because using Pythagorean Theorem, you get that MN=√4+36=2√10, which is (3).
The midpoint of MN can be found by finding the average of the coordinates of M and N. Therefore, our first part to solving this question is to find the coordinates of M and N. M is (2,5) and N is (4,-1). Finding the average of the x-coordinates gives us 3. Finding the average of the y-coordinates gives us 2, Therefore, the midpoint of MN is (3,2), or answer choice (3).

-7/10 divided by 2/5 in it's simplest form
To divide fractions, multiply the first fraction (-7/10) by the reciprocal of the second one (5/2). This gives -35/20 which simplifies to -7/4 or -1 3/4.
Explanation:When dividing fractions, the conventional method is to multiply the first fraction, which is the dividend, by the reciprocal of the second fraction, which is the divisor. In this case, let's take the content loaded -7/10 divided by 2/5.
The reciprocal of 2/5 is 5/2. So, to divide -7/10 by 2/5, we instead multiply -7/10 by the reciprocal of 2/5.
-7/10 * 5/2 = -35/20.
Finally, we simplify this to its simplest form, by reducing to the lowest terms. We find that, -35/20= -7/4 or -1 3/4 if expressed as a mixed number.
