Answer:
c) 2.0 m/s^2.
Step-by-step explanation:
Acceleration = change of velocity / time
= (12.5 - 3.5)/4.5
= 9/4.5
= 2.0 m/s^2.
What is the average of the integers from 25 to 41?
27
33
36
66
Answer:
B. 33
Step-by-step explanation:
The average of the terms of a contiguous subsequence of any arithmetic progression is the average of the first and last terms.
To see this, notice that if you remove 25 and 41 from your sequence, then the average of the remaining terms is still given by the average of the extreme terms
Jamie practices singing for 45 minutes every day. Which equation represents the relationship between the total number of minutes (t ) and the number of days (d ) Jamie has practiced?
Answer:
t = 45d
Step-by-step explanation:
Number of days = d
Number of minutes = t
Number of minutes per day = 45 minutes
Total number of minutes of practice after d number of days will be :
t = number of minutes per days * Number of days
t = 45 * d
t = 45d
Liam has 60 seeds and 12 plastic cups, and will plant the same number of seeds in each cup. Whicl equation shows the number of seeds in each cup? es 4 60 - 5 도 A 1260 5-12
Answer:
Number of seeds in each cup = 5 seeds in each cup
Step-by-step explanation:
Given:
Total number of seeds Liam has = 60 seed
Total number of plastics cup = 12 cups
Find:
Number of seeds in each cup
Computation:
Number of seeds in each cup = Total number of seeds Liam has / Total number of plastics cup
Number of seeds in each cup = 60 / 12
Number of seeds in each cup = 5 seeds in each cup

C. the author’s use of details to support his argument for paper bags
D. the author’s use of description to provide personal experience on the topic
Answer:
B.
Step-by-step explanation:
Our landfills will not actually become towering mountains of trash, that's just a hyperbole used by the author to show the destructive impact that trash in large quantities can have.
Write the equation in standard form of the circle whose diameter has endpoints of (-2, 4) and (8,-6).
Answer:
(x - 3)^2 + (y + 1)^2 = 50.
Step-by-step explanation:
The center of the circle is the midpoint of the diameter
= (-2+8)/2 , (4 - 6)/2
= (3, -1).
The radius^2 can be calculated from one point on the circle ( -2, 4) and the center (3, -1).
The radius^2 = (-2-3)^2 + (4- -1)^2
= 25 + 25 = 50.
So the equation of the circle
is (x - a)^2 + (y - b)^ = r^2 where (a, b) is center and radius = r.
= (x - 3)^2 + (y + 1)^2 = 50

Inverse of -1 would be +1
Hope this helps!
Answer:
-6
Step-by-step explanation:
if f(x)=-1
then you plug -1 into the equation then you get 5(-1)-1
then multiply 5 and -1 and get -5
so now youre left with -5-1
-5-1= -6

Please help me with this:
A teacher decorated her classroom with 3 times as many balloons as paper fans. She used 12 fewer streamers than twice the number of paper fans. If the teacher had a total of 120 balloons, paper fans, and streamers, how many of each kind of decoration did she use?
Answer:
She used 22 paper fans, 66 balloons, and 32 streamers.
Step-by-step explanation:
In order to solve this problem, we need to find out the value of the paper fans. Because we need to find out the balloon amount, which is 3 times as much. The amount of streamers is 12 fewer than two times. We can't find it out just yet since we don't know the value of the paper fans. To find it out:
First, let's call the amount of paper fan as "x".
Then, we need to find out the amount of balloons. It is 3 times x. Which is the same as 3x.
The equation is now x + 3x + (?) = 120
We need to find out the amount of the (?).
So, to do that, it says the value is 12 fewer than 2 times the value of x. (x, because it is the amount of paper fans.)
It should be 2x-12.
Now, the equation is x+3x+2x-12=120.
Once we solve it, we know "x" is 22.
Now, we can multiply 3 by 22. Which is 66.
Then we can multiply 22 by 2, which is 44, and subtract 12, which is 32.
To double check, 22 + 44 + 32 = 120.
That's your answer!
Answer:
Step-by-step explanation:
its 22, and 66, and 32
An hour before show time, only 266 people are seated for a movie. . According to ticket sales, 93% of the people have yet to arrive. How many tickets were sold for the movie
Answer:
3800 tickets
Step-by-step explanation:
we are given that,
total people seated:266
yet to come:93%
so the percentage of people who have arrived is 100%-93%=7%
and one ticket for each people
therefore,
[tex] \displaystyle \begin{array}{ccc} \displaystyle \rm7\% \quad \text{People} \implies266 \: \text{tickets} \\ \displaystyle100 \%\: \quad \imath \imath \implies \frac{266}{7\%} \: \: \: \: \imath \imath \\ \\ \qquad \displaystyle \qquad\rm as \: \% = \frac{1}{100} \longleftarrow \frac{266}{ \dfrac{7}{100} } \\ \\ \displaystyle \rm \: by \: simplifying \: complex \: fraction\longleftarrow 266 \times \frac{100}{7} \\ \rm reduce \: fraction \longleftarrow 38 \times 100 \\ \rm simplify \:multiplication \longleftarrow3800\end{array}[/tex]
hence,
3800 tickets were sold for the movie
Answer:
Solutions given:
[100%-97%]=266people
7% =266people
Each people is 1 ticket.
266 people =266tickets
so
7% of people=266ticket
100% of people =266/7×100=3800tickets
3800tickets were sold for the movie
How many complex roots does the polynomial equation below have?
X^7-3x^5+4^2-1=0
Answer:
4
Step-by-step explanation: 5 22 8 18 e
Graph the function and look for sign changes in the slope (easiest)
of the 7 roots 3 are real and 4 are complex
or the perferred way is to apply Descartes rule of signs
x^7-3x^5+4x^2-1=0 a typo in your function attached photos shows 4x²
(x^7) - (3x^5) +(4x^2) - (1) sign changes I see 3
then to find a bound on the number of negative roots
(-x^7) - (-3x^5) +(4x^2) - (1) = -x^7 + 3x^5 + 4x^2 - 1 I see 2 sign changes ??
there is at least 1 real root (due the odd highest power)
and either 0, 2, 4 or 6 complex roots
so 5 and 7 are out
still confused I used a polynomials root calculator
it said ther are three real roots (confirmed by the graph of the function)
and four comple roots (which I can't figure out from the graph)

What voltage is required to force 4.5 amperes of current through an electric iron having a resistance of 25.5 ohms
Answer:
V = 114.75 Volts
Step-by-step explanation:
Ohm's Law V = IR
I = 4.5 A
R = 25.5 Ω
V = (4.5)(25.5)
V = [4×25.5] + [0.5×25.5]
V = 102 + 12.75
V = 114.75 Volts
In APQR, T, U and S are points of tangency. PR = 12 units. Find TR.
Answer:
TR = 3 units
Step-by-step explanation:
PR = 12 units
PS = 9 units
PU = PS = 9 units (tangents drawn from an external point are congruent)
RU = PR - PU
RU = 12 - 9
RU = 3 units
TR = RU = 3 units (tangents drawn form an external point of a circle)
TR = 3 units

Katy put $3000 into his bank account. If the account pays 6% interest compounded continuously, when will it be worth $6000? Round to 3 decimal places.
Answer:
11.55 years
Step-by-step explanation:
Given data
Principal= $3000
Rate= 6%
Final Amount= $6000
expression for the time is given as
t = ln(A/P) / r
Substitute
t= ln(6000/3000)/0.06
t= ln(2)/0.06
t= 0.693/0.06
t= 11.55 years
Hence the time is 11.55 years
If the graph of y = - x ^ 2 translated horizontally 7 units to the right and translated vertically 6 units upwards, what’s the new equation?
9514 1404 393
Answer:
y = -(x -7)² +6
Step-by-step explanation:
Replacing x with (x-h) translates the graph h units to the right. You want h=7.
Replacing f(x) with f(x)+k translates the graph k units upward. You want k=6.
These transformations make the new equation be ...
y = -(x -7)² +6
