Answer:

588cm3

Step-by-step explanation:

Since the base is 7cm, and it is a cereal box, that means the depth is also 7cm.

Hence,

7x12x7=588

Part 1

[tex]x = g(y), \ c \le y \le d\\\\\\x = 3+4y^2, \ 1 \le y \le 2\\\\\\\frac{dx}{dy} = 8y, \ 1 \le y \le 2\\\\\\\displaystyle A = 2\pi \int_{c}^{d}y\sqrt{1+[g'(y)]^2}dy\\\\\\\displaystyle A = 2\pi \int_{c}^{d}y\sqrt{1+\left[\frac{dx}{dy}\right]^2}dy\\\\\\\displaystyle A = 2\pi \int_{1}^{2}y\sqrt{1+(8y)^2}dy\\\\\\\displaystyle A = 2\pi \int_{1}^{2}y\sqrt{1+64y^2}dy\\\\\\\displaystyle A = 2\pi \int_{1}^{2}\sqrt{1+64y^2}*ydy\\\\\\\displaystyle A = 2\pi \int_{65}^{257}\sqrt{u}*\frac{du}{128}\\\\\\[/tex]

In the last two steps I let u = 1+64y^2, so du/dy = 128y which leads to ydy = du/128.

Note the change in the limits of integration. If y = 1, then u = 1+64y^2 = 65. If y = 2, then 1+64y^2 = 257

----------------------------

Part 2

[tex]\displaystyle A = 2\pi \int_{65}^{257}\sqrt{u}*\frac{du}{128}\\\\\\\displaystyle A = 2\pi*\frac{1}{128}\int_{65}^{257}u^{1/2}*du\\\\\\\displaystyle A = \frac{\pi}{64}\int_{65}^{257}u^{1/2}*du\\\\\\\displaystyle A = \frac{\pi}{64}\left(\frac{2}{3}u^{3/2}+C\right)\Bigg]_{65}^{257}\\\\\\\displaystyle A = \frac{\pi}{64}\left(\left(\frac{2}{3}(257)^{3/2}+C\right)-\left(\frac{2}{3}(65)^{3/2}+C\right)\right)\\\\\\\displaystyle A = \frac{\pi}{64}*\frac{2}{3}\left((257)^{3/2}-(65)^{3/2}\right)\\\\\\[/tex]

----------------------------

Part 3

[tex]\displaystyle A = \frac{\pi}{96}\left(\sqrt{257^3}-\sqrt{65^3}\right)\\\\\\\displaystyle A = \frac{\pi}{96}\left(\sqrt{257^2*257}-\sqrt{65^2*65}\right)\\\\\\\displaystyle A = \frac{\pi}{96}\left(\sqrt{257^2}*\sqrt{257}-\sqrt{65^2}*\sqrt{65}\right)\\\\\\\displaystyle A = \frac{\pi}{96}\left(257\sqrt{257}-65\sqrt{65}\right)\\\\\\[/tex]

[tex]\displaystyle A = \frac{\pi}{96}*257\sqrt{257}-\frac{\pi}{96}*65\sqrt{65}\\\\\\\displaystyle A = \frac{257\pi\sqrt{257}}{96}-\frac{65\pi\sqrt{65}}{96}\\\\\\\displaystyle A = \frac{-65\sqrt{65}\pi}{96}+\frac{257\sqrt{257}\pi}{96}\\\\\\[/tex]

Answer:

$31.50

Step-by-step explanation:

To solve this problem, create the equation

y = 0.10x + 25

Where x is equal to the number of international minutes and y is equaled to the total price paid. Since we are give the number of international minutes (the x), plug this into the equation and solve for y.

y = 0.10(65) + 25

y = 6.5 + 25

y = 31.5 or $31.50

Answer:

x = 2

Step-by-step explanation:

Vertical angles are equal to each other. It means that,

∠A = ∠B

So,

20x+10 = 30x−10

Taking like terms together, we get :

20x-30x=-10-10

-10x=-20

x=2

So, the value of x is 2.

You multiply 3 times x and you get 3x, then multiply 3 times negative 13 and you get -39.

3x-39

Answer:

✔️Segment EF is twice as long as segment AB

✔️The length of segment EH is 16 units.

Step-by-step explanation:

Since quadrilateral ABCD is scaled to form quadrilateral EFGH, both are similar polygon.

Therefore: scale factor = ratio of any of their corresponding side

Scale factor = GH/CD = 12/6 = 2

This means quadrilateral EFGH is twice the size of quadrilateral ABCD.

The shape of the original polygon remains the same while the size increases.

This implies that, all segments of quadrilateral ABCD increases proportionally times 2 to give us corresponding lengths of the segments of quadrilateral EFGH.

Since shape remains the same, their corresponding angles are congruent and the same in measure.

Therefore, the following statements are true and correct:

✔️Segment EF is twice as long as segment AB

(EF = AB*scale factor = 3*2 = 6)

✔️The length of segment EH is 16 units.

(EH = AD*scale factor = 8*2 = 16)

Answer:

he total time is 4 seconds. The elevator descends 10 feet each second so the total is:

4seconds x -10 feet/sec = -40 feet

The total change in elevation is -40 feet. You need the negative sign because the elevator is moving downward. Hope this helps!

Answer:

ab - a - b + 1 = (a - 1)(b - 1)

Step-by-step explanation:

Let us explain factorization by grouping

In the expression of 4 terms ax + by + bx + ay

Take every two terms have a common factor in a bracket

Take the common factor out of the brackets

Take the bracket as a common factor

Let us do these steps with our question

∵ ab - a - b + 1 is an expression of 4 terms

→ Take ab and a in a bracket, -b and 1 in another bracket

∴ ab - a - b + 1 = (ab - a) + (-b + 1)

→ Take a as a common factor from the 1st bracket and -1 from

   the 2nd bracket

∴ (ab - a) + (-b + 1) = a(b -1) + -1(b - 1)

→ Take the bracket (b - 1) as a common factor

∴ a(b -1) + -1(b - 1) = (b - 1)(a + -1)

∵ (+)(-) = (-)

∴ (b - 1)(a + -1) = (b - 1)(a -1)

→ Change the order of the bracket

∴ (b - 1)(a -1) = (a - 1)(b - 1)

∴ ab - a - b + 1 = (a - 1)(b - 1)
