A submarine is 4,000 feet below sea level, and rising a rate of 100 feet pre minute. Write an equation to represent y, the depth of the submarine after x minutes.

Answer:

D: 0 and 1

Step-by-step explanation:

Function is defined by;

f(x) = 3x^(5) - 5x⁴

Now, an inflection point will be a point on the graph where the inflection or concavity changes.

Thus, let's find the derivatives until we get there;

f'(x) = 15x⁴ - 20x³

f''(x) = 60x³ - 60x²

So factorizing gives;

f''(x) = 60x²(x - 1)

At f''(x) = 0, we have; x = 0 or x = 1

Thus, the x coordinates of points of inflection are 0 & 1

Answer:

5.75

Step-by-step explanation:

1.25 +4.5 =5.75(the time =the addition of the both times)

The product of the numbers 2.7 x 6.4 using partial products is 17.28

In order to get the product of the values using partial products, we will use the concept of repeated addition as shown:

2.7 x 6.4

For 2.7 = 2.0 + 0.7

6.4 = 6.0 + 0.4

Substituting the sum into the product, we will have:

2.7 x 6.4 = (2.0 + 0.7)  x (6.0 +0.4)

2.7 x 6.4 = 2.0(6.0) + 2(0.4) + 0.7(6) + 0.7(0.4)

2.7 x 6.4 = 12 + 0.8 + 4.2 + 0.28

2.7 x 6.4  = 17.28

Therefore, the value is 17.28.

The correct option is b). No. The student's construction is not correct because circle D and circle E are not the same size.

An angle bisector is a ray, segment, or line which divides a provided angle into two equal-sized angles. The term bisector or bisection refers to the process of dividing something into two equal parts.

Now, as per the given question;

If line AH is the angle bisector of angle DAE, circle D as well as circle E should be the same size to ensure triangle ΔHDA ≅ Δ HEA, from which ∠ DAH= ∠EAH is deduced. Angle bisector properties

Thus, the student's construction again for angle bisector of DAE is incorrect because circle D or even circle E aren't the same size.

Step-by-step explanation:

Answer:

[tex]r=1.05\ \text{ft}[/tex]

[tex]h=2.12\ \text{ft}[/tex]

[tex]20.91\ \text{ft}^3[/tex]

Step-by-step explanation:

r = Radius

h = Height

Volume of cylinder = [tex]7.35\ \text{ft}^3[/tex]

[tex]V=\pi r^2h\\\Rightarrow h=\dfrac{V}{\pi r^2}\\\Rightarrow h=\dfrac{7.35}{\pi r^2}[/tex]

Surface area is given by

[tex]A=2\pi r^2+2\pi rh\\\Rightarrow A=2\pi r^2+2\pi r\dfrac{7.35}{\pi r^2}\\\Rightarrow A=2\pi r^2+\dfrac{14.7}{r}[/tex]

Differentiating with respect to radius we get

[tex]\dfrac{dA}{dr}=4\pi r-\dfrac{14.7}{r^2}[/tex]

Equating with zero we get

[tex]0=4\pi r-\dfrac{14.7}{r^2}\\\Rightarrow 4\pi r=\dfrac{14.7}{r^2}\\\Rightarrow r^3=\dfrac{14.7}{4\pi}\\\Rightarrow r=(\dfrac{14.7}{4\pi})^{\dfrac{1}{3}}\\\Rightarrow r=1.05[/tex]

[tex]\dfrac{d^2A}{dr^2}=4\pi-2\times \dfrac{14.7}{r^3}\\\Rightarrow \dfrac{d^2A}{dr^2}=4\pi+2\times \dfrac{14.7}{1.05^3}\\\Rightarrow \dfrac{d^2A}{dr^2}=37.96>0[/tex]

So, the value of the function is minimum at [tex]r=1.05[/tex]

[tex]h=\dfrac{7.35}{\pi r^2}=\dfrac{7.35}{\pi 1.05^2}\\\Rightarrow h=2.12[/tex]

So, the radius and height which would minimize the surface area is 1.05 feet and 2.12 feet respectively.

Surface area

[tex]A=2\pi r^2+2\pi rh\\\Rightarrow A=2\pi \times 1.05^2+2\pi 1.05\times 2.12\\\Rightarrow A=20.91\ \text{ft}^3[/tex]

The minimum surface area is [tex]20.91\ \text{ft}^3[/tex].

y - 35 = 2(x - 10)

Step-by-step explanation:

Let

y----->  the height of the plant

x ----> the number of days

Find the slope

we have the points

(10,35)

The slope is equal to

m= (55-35)/(20-10)

m= 2

Find the equation of the line into point slope form

y- y1 = m(x - x1)

we have

m= 2 and point (10,35)

y - 35 = 2(x - 10)

Step-by-step explanation:

3x + 2y = 22 ....... (1)

- x+ 4y = 22 ........ (2)

3 × (2) + (1)

(3x - 3x) + (2y + 12y) = 22 + 66 ( variable "x" is eliminated )

Answer:

After 5 months, both options will have saved 450$

Step-by-step explanation:

The first option can be modeled with the expression

400 + 10x

The second option can be modeled with the expression

300 + 30x

The variable x represents the months so in order to find the month where Tina saves the same amount, we set the expressions equal to each other.

400 + 10x = 300 + 30x

solve for x

20x = 100

x = 5
