Answer:

(4k+5)+ (6k+10) = 115

Exterior angle of a triangle is equal to the sum of two opposite interior angles

10k=15=115

10k= 100

k = 100/10

k = 10

Step-by-step explanation:

Answer:

k = 10

Step-by-step explanation:

The 3rd angle that's not defined in the equation is supplementary to 115, so the angle is 180-115 = 65.

We can solve for the equation 65+(4k+5)+(6k+10)=180 -> 65+4k+5+6k+10=180 -> 10k+80 = 180 -> 10k = 100 -> k = 10.

To double-check(optional), we can plug k back into the equation, so 65 + 4*10 + 5 + 6*10 + 10 = 180 -> 100 + 65 + 5 + 10 = 180 -> 180 = 180, so we can confirm that k = 10.

Answer:

(2,440.1 mi)

Answer:

440,000

Step-by-step explanation:

The given number i.e. 441,902 rounded to the nearest ten thousand should be considered as the 440,000.

Since the given number is 441,902

We have round the above number to the nearest ten thousand

Since the thousand is less than 5,000 so here it should be 440,000

hence, The given number i.e. 441,902 rounded to the nearest ten thousand should be considered as the 440,000.

Answer:

1.

Collinear points mean they are on the same line. That leaves us with answer d. F, E, G

2.

In this case, the intersection of the 2 planes is a line. 2 points both planes contain are B and C, so the intersection can be named as answer b: Line BC

3.

2 points define a line, so therefore the answer to the question is answer b. 1

Answer:

1999

Step-by-step explanation:

The equation which represents the given situation is P=180t+620.

Given that, the population at time t=3 is 1160 and at time t=5 is 1520, where t is the number of years after 1990​.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Now, the standard form of the population is increasing linearly is P = mt + b.

Where m is the slope = (y2-y1)/(x2-x1)=(1520-1160)/(5-3)

=360/2

=180

So, 1160=180 × 3 + b

⇒ 1160=540 × 3 + b

⇒ b=620

Then, the equation is P=180t+620

Therefore, the equation which represents the given situation is P(t)=180t+620.

Answer:

[tex]\displaystyle \frac{2}{n} \sum_{i = 1}^{n} \left(\left(\frac{2i}{n}\right)^3 - \frac{2i}{n}\right)[/tex]

Step-by-step explanation:

We have the sum:

[tex]\displaystyle \left[\left(\frac{2}{n}\right)}^3-\frac{2}{n}\right]\left(\frac{2}{n}\right)+...+\left[ \left(\frac{2n}{n}\right)^3-\frac{2n}{n}\right]\left(\frac{2}{n}\right)[/tex]

And we want to find the sigma notation that represents the sum.

Note that the leftmost term is the first term while the rightmost term is the last term.

n is the number of terms. Therefore, (2 / n) will stay constant. Hence, we can factor it out of the series:

[tex]\displaystyle =\frac{2}{n}\left(\left[\left(\frac{2}{n}\right)^3-\frac{2}{n}\right]+...+\left[\left(\frac{2n}{n}\right)^3-\frac{2n}{n}\right]\right)[/tex]

Notice the differences between the first term and the last term. The first term is given by [tex]\displaystyle \left(\frac{2}{n}\right)^3- \frac{2}{n}[/tex]. The last term is given by  [tex]\displaystyle \left(\frac{2n}{n}\right)^3- \frac{2n}{n}[/tex]. Because at the last term, our initial term i is equal to n, we can replace the extra n with i for our summation.

Therefore, we can write the following summation:

[tex]=\displaystyle \sum_{i=1}^{n} \frac{2}{n}\left(\left[\left(\frac{2i}{n}\right)^3-\frac{2i}{n}\right]\right)[/tex]

And since (2 / n) is constant:

[tex]\displaystyle = \frac{2}{n} \sum_{i = 1}^{n} \left(\left(\frac{2i}{n}\right)^3 - \frac{2i}{n}\right)[/tex]

Answer:

$-748.38

Step-by-step explanation:

Net proceeds = Total cost of selling the stock - Total cost of purchasing the stock

Total cost of purchasing the stock = $7000 + ($7000 x 0.015) = $7105

Total cost of selling the stock = $6,325 + ($6,325 x 0.005) = $6356.63

Net proceeds = $6356.63 - $7105 = $-748.38

Answer:

y=5/8x+4.5

Step-by-step explanation:

You have to do y-y divided by x-x so 7-2 which equals 5 and 4-(-4) which equals 8 so your slope is 5/8. For y-intercept, you have to do plug in one of your points into y and x in y=mx+b, so I used the point (4, 7) and I put 7 in the y spot and 4 in the x spot and I put the slope in the slope spot so now you have 7=5/8(4)+b. Next, you multiply 5/8 and 4 which gives you 5/2 or 2.5, so now you have 7=2.5+b. Then you subtract 7-2.5 which gives you 4.5 and there is your y-intercept and your whole equation is y=5/8x+4.5.
