Find the results of the given vector subtractions for u = <-8, 4> and V = <2,7>.
Answers
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 >

In a survey of 100 people, some of them jog for exercise, some of them ride a bike, some do both, and 15 do not jog or ride a bike. If 46 of the people surveyed job and 21 of them both jog and ride a bike, how many of the people surveyed only ride a bike?
Answers
Answer:
Bike alone = 39
Step-by-step explanation:
Given that:
Total number = n(T) = 100
Jog= n(J)
Bike = n(B)
Bike and jog = n(BnJ) = 21
Number who jog = 46
Jog alone = 46 - 21 = 25
Neither jog nor bike = 15
Let bike alone = x
Hence,
Jog alone + bike alone + jog and bike + none of the two = 100
25 + x + 21 + 15 = 100
x = 39

B) The locations of A' and B' are A' (0, 6) and B' (2, 0); lines f and f' intersect at point B. C) The locations of A' and B' are A' (0, 2) and B' (2, 0); lines f and f' are the same line. D) The locations of A' and B' are A' (0, 6) and B' (6, 0); lines f and f' are parallel.
Answers
Answer:
D (0,6) (6,0)
Step-by-step explanation:
when you multiply it you do the x coordinates first then the y.
so (0,2) x 3 = (0,6)
(2,0) x 3 = (6,0)
These coordinates are parralel to each other.
The locations of A' and B' are A' (0, 6) and B' (6, 0); lines f and f' are parallel, the correct option is D.
What is Transformation?Transformation is the process of changing the graph to a new graph by Rotation, Reflection, Translation, and Dilation.
Dilation is a process in which the object or the graph is enlarged or compressed by a scale factor.
The coordinates of A( 0, 2)
The coordinates of B(2,0)
The scale factor is 3
The center of dilation of f is at the origin to create line f'.
The points A and B lie on the line f, when line f is dilated, the coordinates will also get dilated.
The coordinate of A after dilation is 3 * (0,2)
A' = (0,6)
The coordinate of B after dilation is 3 * (2,0 )
B' = (6,0)
The line f' will be parallel to the line f.

The test scores you end up having in geometry class are 81 and 87. What possible scores can you earn on your next test to have a test average between 84 and 89?
Answers
Answer:
88, 89, 90, 91, 92? idrk
Answer:
A score between 84 and 99
Step-by-step explanation:
First, let's solve for what you would need to score on your next test to have an average of 84:
(81 + 87 + x)/3 = 84
(168 + x)/3 = 84
168 + x = 252
x = 84
Next, let's solve for what you would need to score on your next test to have an average of 89:
(81 + 87 + x)/3 = 89
(168 + x)/3 = 89
168 + x = 267
x = 99
That means you would have to earn a score between 84 and 99.
I hope this helped you, and if it did, a brainliest would be appreciated :)
Heather made $299 for 13 hours of work.
At the same rate, how much would she make for 18 hours of work?
Answers
Answer:
$414
Step-by-step explanation:
We know that Heather made $299 for 13 hours of work.
So, to find how much Heather will make for 18 hours of work at the same rate, we can write and solve for the following proportion:
[tex]\frac{299}{13}=\frac{x}{18}[/tex]
Notice that we align the rates vertically and the measurements horizontally (dollars in the numerator and hours in the denominator).
So, to find how much Heather will make for 18 hours, we will solve for x. Cross-multiply:
[tex]13x=5382[/tex]
Divide both sides by 13:
[tex]x=\$414[/tex]
So, Heather will make $414 for 18 hours of work.
And we're done!

Answers
Answer:
4
Step-by-step explanation:
edge
The average rate of the function is 4.
What is average rate of function?The average rate of change of a function f(x) over an interval [a, b] is defined as the ratio of "change in the function values" to the "change in the endpoints of the interval". i.e., the average rate of change can be calculated using [f(b) - f(a)] / (b - a). In other words, the average rate of change (which is denoted by A(x)) is the "ratio of change in outputs to change in inputs". i.e.,
A(x) = (change in outputs) / (change in inputs)
= Δy / Δx
= [f(b) - f(a)] / (b - a)
given function:
f(x) = -x² + 6x + 12
Now,
let a= -3, b = 5
and, f(b)= -(5*5) + 6*5 + 12
=-25+ 30 +12
= 17
f(a) = -(- 3 * (-3))+6(-3) +12
= -9-18+12
= -15
Now,
f(b)- f(a) / (b-a)
=17 -(-15))/5-(-3)
=32/ 8
=4

Wally's grandmother started a college savings account for him with
$3,000. What is the total amount of money in the account after 5 years if
the annual simple interest rate is 3%?
I need this plz help explain the proses thx ASAP
Answers
Answer:
$450
Step-by-step explanation:
You want to calculate the interest on $3000 at 3% interest per year after 5 year(s).
The formula we'll use for this is the simple interest formula, or:
Where:
P is the principal amount, $3000.00.
r is the interest rate, 3% per year, or in decimal form, 3/100=0.03.
t is the time involved, 5....year(s) time periods.
So, t is 5....year time periods.
To find the simple interest, we multiply 3000 × 0.03 × 5 to get that:
The interest is: $450.00
Usually now, the interest is added onto the principal to figure some new amount after 5 year(s),
or 3000.00 + 450.00 = 3450.00.

C. f(x) has an inverse function, because its graph passes the vertical
line test.
D. f(x) does not have an inverse function, because its graph fails the
vertical line test.
Answers
Answer:
f(x) does not have an inverse function, because its graph fails the horizontal line test. ⇒ A
Step-by-step explanation:
The vertical line test is used to show that the graph represents a
function or not
If the vertical line crosses the graph in more than one point, then the graph does not represent a functionIf the vertical line crosses the graph in only one point in different positions, then the graph represents a functionThe horizontal line test is used to show that the function has an
inverse or not
If the horizontal line crosses the graph of a function in more than one point, then the function has no inverseIf the horizontal line crosses the graph of a function in only one point in different positions, then the function has an inverseLet us look at the given graph
→ The graph represents a parabola, which represents the function f(x)
∵ Any horizontal line drawn will cross the graph in more than one point
∴ f(x) has no inverse
∴ f(x) does not have an inverse function, because its graph fails the
horizontal line test.
