SMART PPL PLEASE HELP ,Explain how you know the expression represents the area of shaded part of the rectangle.

Answer:

y=1/2x+1

Step-by-step explanation:

Answer:

Step-by-step explanation:

First you want to mark 2 points. I chose (-2,0) and (2,2), it does not mater what points you chose. Once you have the two points, you need to find the slope. To calculate the slope can be seen below.

Slope (m) = ΔY/ΔX = 1/2 = 0.5

Once you have the slope, which is 0.5, you fill in this equation.

y = mx + b, where m is the slope and b is the y-intercept.

Now filling in given variables, you get this equation.

y = 0.5x + 1

Answer: Meaghan is right.

Step-by-step explanation:

For a number like:

123.45

the tens place would be the "2" (second number at the left of the decimal point)

The ones place would be the "3" (first number at the left of the decimal point)

Let's suppose that Lily is correct.

Then the quotient of:

43.61/7

Will be a number with two digits in the left of the decimal point.

The smallest number that meets this condition, is the number 10.

Then let's see:

7*10 = 70

then:

70/7 = 10

and:

43.61 < 70

(70 is larger than 43.61)

then:

43.61/7 < 70/7 = 10

Then:

(43.61/7) < 10

This means that our quotient is smaller than 10, then the first digit of the quotient can not be on the tens place.

Then Meaghan is the correct one.

We also could perform the quotient to find:

43.61/7 = 6.23

So yes, Meaghan is correct.

The x = 3 the quadratic equation D) y = 2x² -3x +7 will have maximum value.

The maximum and minimum values of a function:

The maximum and minimum values are the highest and lowest values that a function can reach over a particular domain.

For example, in a quadratic function, the maximum or minimum value is the highest or lowest point on the graph, respectively.

If a function has a maximum value, it means that the function reaches its highest point at a certain value of x.

On the other hand, if a function has a minimum value, it means that the function reaches its lowest point at a certain value of x.

Here we have

(A) y = x²-6x +19  

At x = 3

y = (3)² - 6(3) + 19  

= 9 - 18 + 19 = 10

(B) y = -4x²+24x -21

At x = 3

y = -4 (3)² + 24(3) - 21

= - 4(9) + 72 - 21

= 15

(C) y= -2x² +20x -49

At x = 3

y = - 2 (3)² + 20(3) - 49

= - 18 + 60 - 49

= - 7

(D) y = 2x² -3x +7    

At x = 3

y = 2(3)³ - 3(3) + 7

= 18 - 9 + 7

= 16

Therefore,

The x = 3 the quadratic equation D) y = 2x² -3x +7 will have maximum value.

Answer:

(8,8)

Step-by-step explanation:

The first equation says y and x are the same, so any x in the second equation can be replaced with a y, so

y = 2x - 8 and y = x, substituting x for y gives

x = 2x -8, subtract x from each side, add 8 to each side, get

8 = x

substitute that value back into the first equation

y = x, x= 8, so y=8

Answer:

4th option OR last option

Step-by-step explanation:

Ok so I think it means hexagon not heptagon since I have never heard of heptagon. Just confirm that with your teacher if it is hexagon or heptagon.

Hexagon = 6 sides

This means that it is not second option. Nor it is the third option since it said that it should be more than 6 sides. Now we are left with 1st and 4th option. It also mentioned that all opposite sides should be parallel. Looking at the first option, not all sides are parallel. Some are big and some are small. This remains with the last option which is the 4th option.

Hope this helps, thank you !!

Answer:

About 0.6548 grams will be remaining.  

Step-by-step explanation:

We can write an exponential function to model the situation. The standard exponential function is:

[tex]f(t)=a(r)^t[/tex]

The original sample contained 510 grams. So, a = 510.

Each half-life, the amount decreases by half. So, r = 1/2.

For t, since one half-life occurs every 38 days, we can substitute t/38 for t, where t is the time in days.

Therefore, our function is:

[tex]\displaystyle f(t)=510\Big(\frac{1}{2}\Big)^{t/38}[/tex]

One year has 365 days.

Therefore, the amount remaining after one year will be:

[tex]\displaystyle f(365)=510\Big(\frac{1}{2}\Big)^{365/38}\approx0.6548[/tex]

About 0.6548 grams will be remaining.  

Alternatively, we can use the standard exponential growth/decay function modeled by:

[tex]f(t)=Ce^{kt}[/tex]

The starting sample is 510. So, C = 510.

After one half-life (38 days), the remaining amount will be 255. Therefore:

[tex]255=510e^{38k}[/tex]

Solving for k:

[tex]\displaystyle \frac{1}{2}=e^{38k}\Rightarrow k=\frac{1}{38}\ln\Big(\frac{1}{2}\Big)[/tex]

Thus, our function is:

[tex]f(t)=510e^{t\ln(.5)/38}[/tex]

Then after one year or 365 days, the amount remaining will be about:

[tex]f(365)=510e^{365\ln(.5)/38}\approx 0.6548[/tex]

Step-by-step explanation:

Answer:

-12.5

Step-by-step explanation:

If you do 2.50*5 (because Ms. Ortiz borrows $2.50 every day for 5 days) it equals 12.5, and since it's how much she owes, you have to make it negative, so it's -12.50 or she owes $12.50 (the first one if you are supposed to have the answer be negative, the second one if you have to have it in money form).

,LCM of 12 and 30 is 60

Answer:

List the first five multiples of 30

The first 5 multiples of 30 are: 0, 30, 60, 90, 120.

What is the lowest common multiple of 12 and 30

for LCM (12,30) we find:

Prime factorization of 12 = 2 × 2 × 3.

Prime factorization of 30 = 2 × 3 × 5.

Using all prime numbers found as often as each occurs most often we take 2 × 2 × 3 × 5 = 60.

Therefore LCM (12,30) = 60
