Find the results of the given vector subtractions for u = <-8, 4> and V = <2,7>.
Answer:
see explanation
Step-by-step explanation:
- u - v
= - < - 8, 4 > - < 2, 7 > ← multiply each component of u by - 1
= < 8, - 4 > - < 2, 7 > ← subtract corresponding elements
= < 8 - 2, - 4 - 7 >
= < 6, - 11 >
----------------------------------------------------------
u - v
= < - 8, 4 > - < 2, 7 > ← subtract corresponding elements
= < - 8 - 2, 4 - 7 >
= < 6, - 3 >
-----------------------------------------------------------
v- u
= < 2, 7 > - < - 8, 4 > ← subtract corresponding elements
= < 2 - (- 8), 7 - 4 >
= < 2 + 8, 7 - 4 >
= < 10, 3 >
For the past three months, Grace used her cell phone for 43 minutes, 62 minutes, and 57 minutes. How many minutes would she have to use her cell phone this month for the average usage over the four months to be 55 minutes? Be sure to include units in your answer
Answer:
Step-by-step explanation:
If they want the average for four months to be 55 minutes, this means that the total of the four months = 55 x 4
Total of four months = 220 minutes
They already told us that the three previous months she used her cellphone for 43 minutes, 62 minutes and 57 minutes.
All you have to do now is subtract everything from the total of the four months.
4th month = 220 - 43 - 62 - 57
= ? Minutes

Here are three different recipes for Orangey-Pineapple Juice. Two of these mixtures taste the same and one tastes different.
Recipe 1: Mix 4 cups of orange juice with 6 cups of pineapple juice.
Recipe 2: Mix 6 cups of orange juice with 9 cups of pineapple juice.
Recipe 3: Mix 9 cups of orange juice with 12 cups of pineapple juice.
Which two recipes will taste the same, and which one will taste different?
Answer:
Recipe 1 and 2 will taste the same .
Step-by-step explanation:
they will taste same because they have equal ratios
1.4:6=2:3
2.6:9=2:3
3.9:12=3:4
2:3 =2:3
recipe 1 and 2 are same.
Martina opens a savings account with an initial deposit and makes no other deposits or withdrawals. She earns interest on her initial deposit. The total amount of money in her savings account at the end of each year is represented by the sequence shown.
100, 105, 110.25, ...
Which recursive formula can be used to determine the total amount of money earned in any year based on the amount earned in the previous year?
A. f(n + 1) = f(n) + 5
B. f(n + 1) = 5f(n)
C. f(n + 1) = 1.05f(n)
D. f(n + 1) = 0.05f(n)
1.05 should be it
Step-by-step explanation:
In a recursive formula, each term of the sequence is found by using the previous term. In this case, the sequence is geometric because we are multiplying each term by the same constant, called a common ratio.
To find this common ratio, we find the percent of change between terms. We do this by using the formula
% change = (amount of change)/(original amount)
The amount of change between the first two terms is 105-100 = 5. This makes the percent change
5/100 = 0.05
The amount of change between the second two terms is 110.25-105 = 5.25. This makes the percent change
5.25/105 = 0.05
However, the common ratio in the sequence is not 0.05. This is because multiplying by this decimal would make the terms decrease instead of increasing. In this case, we are taking 100% of the number and adding an extra 5% (0.05 = 5%); this makes our common ratio 105% = 1.05.
This gives us the recursive formula

Karen is driving across the country. The longer she drives after filling her gas
tank, the more gas she will have to put in next time she fills up.
A. The amount of time that Karen has driven since she last put gas in
her car is a function of how much gas her car needs.
B. The amount of gas Karen has to put in her tank is a function of
how large her gas tank is.
C. The amount of gas Karen has to put in her tank is a function of
how long she has driven since she last put gas in.

Is 1.888... an irrational number? (i have a 1 in math :C)
Answer: No, 1.888 is a rational number. In mathematics, the irrational numbers are all the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers. When the ratio of lengths of two line segments is an irrational number, the line segments are also described as being incommensurable, meaning that they share no "measure" in common, that is, there is no length ("the measure"), no matter how short, that could be used to express the lengths of both of the two given segments as integer multiples of itself.

£432.75 to 2 significant figure, is 4.3275*10²
What is a significant figure?The term significant figures refers to the number of important single digits (0 through 9 inclusive) in the coefficient of an expression in scientific notation.
Given a term £432.75
Rounding £432.75 to 2 significant figure, we get,
432.75 = 4.3275*10²
Hence, 432.75 to 2 significant figure, is 4.3275*10²

Which ones are correct please help me.
Answer:
I think it's the third choice because line segments are congruent and not equal. Line segments also have little lines on top of the letters.
Step-by-step explanation:
======================================================
Explanation:
AB = BC refers to the fact that expressions 2x+7 and 4x-3 are equivalent. They represent numbers when we replace x with some number. So after doing that replacement, we have something in the form number = number.
So this is why choice A is one of the answers.
[tex]\overline{AB} \cong \overline{BC}[/tex] says "segment AB is congruent to segment BC". The horizontal lines over the lettering indicates we have a segment. The equal sign with a squiggle over top is the congruence symbol. In geometry, we say two items are congruent if they are the same. You can think of making a clone of the object and then sliding it over. In this case, we've cloned segment AB to form segment BC.
This is why choice C is the other answer.
--------------
Choices B and D are close, but not quite correct. Choice B is missing the segment markers. Choice D is missing the congruence symbol. Congruence and equality are very similar ideas, so often they get mixed up.
