Firstly, we will select three corner points

A=(2,3)

B=(6,8)

C=(7,4)

we are given

the transformation with the rule (x, y)→(x, −y)

y--->-y

so, it is reflected about x-axis

so, we will multiply y-value by -1

we get new points as

A=(2,-3)

B=(6,-8)

C=(7,-4)

now, we can locate these points and draw graph

we get

Answer:

Option C is the correct choice that is $y$

Step-by-step explanation:

As this is a multiple choice question we will reduce the options and work on it with the given points $(0,-2),(-2,-3)$

Note:We know that $\leq ,\geq$ where there is $=$ sign associated with it have a straight line graph there is no breaking in the line.

And when there is simply we have a dashed line when we plot it on a graph.

So option B and D are discarded.

Now one-by one we will put the values $(x,y)\ (-2,3)$ to know which equation it satisfies.

If we put $y=3$ then $x=-2$ .

So working with option A.

$y$

Plugging the values.

$3$

And we know that $x$ must be equal to $-2$ so this is not the right answer.

We are left with only one choice that is C .

So option C is the correct option of the above inequality.

Student council expects $150 students for a dance and spends $10 on food for each student. The council expects the number of stu

Natalija [7]

Answer:

$A) S(t)=150(1.08)^{t-1}$ $B) A(t)=10(0.96)^{t-1}$

$C) If\:t = 1\\E(t)=150\times10\\ \\If\:t >1\\E(t)=150(1.08)^{t-1}\times10(0.96)^{t-1}$

Step-by-step explanation:

Considering that The Student Council expects to 150 students for a dance, and spends $10 per student.

If the expectancy is that the number of students increases by 8%

Then since the growth is 8%

we can write the the Predicted Number of Students as a Geometric Sequence,

$a_{1}=150\\a_{2}=150\times 1.08 =162\\a_{3}=162\times 1.08= 174.96\approx 175\\a_{4}=175\times1.08=189\\a_{5}=189\times 1.08=204.12\approx 204\\$

Therefore,

$S(t)=150(1.08)^{t-1}$

B) If we spend $10 per student on the 1st year, but the Council wants to reduce the expenditure 4% yearly. Since we want to reduce 4% we must multiply by 96%.

$b_{1}=10\\b_{2}=10*(0.96)=9.6\\b_{3}=9.6*(0.96)=9.22\\b_{4}=9.22*(0.96)=8.85\\b_{5}=8.85*(0.96)=8.50$

Therefore we can write:

$A(t)=10(0.96)^{t-1}$

The total expenditure for food must be reduced, by 4%. As long as the public goes increasing by 8% yearly this

So,

$If\:t = 1\\E(t)=150\times10\\ \\If\:t >1\\E(t)=150(1.08)^{t-1}\times10(0.96)^{t-1}$

Which of the following graphs could be the graph of the function f(x) = x3 + 8?

Gelneren [198K]

It seems you missed to upload graphs given with the question. So i will draw the graph myself then explain the answer.

f(x)=x^3+8 is the given function which is created from parent function f(x)=x^3

Graph of x^3 is like graph of any odd degree function which starts from bottom and goes to top because of positive leading coefficient.

then there is +8 which means parent function is shifted 8 units upward.

You may directly plug some numbers to find points on f(x)=x^3+8 then join those points to get the graph easily.

like we can use numbers x=-2,-1,0,1,2,...

I will show you calculation for x=-2

f(-2)=(-2)^3+8=(-2)(-2)(-2)+8=-8+8=0

Hence first point is (-2,0)

Similarly you can find more points then use them to find the final graph as shown in attached picture.
