A scientist was in a submarine below sea level studying ocean life over the next 10 minutes she went down 58 ft how many feet had she been below sea level if she was 141.5 ft below sea level after she went down

Answer:

The correct answers are:

[tex]\sqrt{0}=0\\\sqrt{1.44} = \pm 1.2\\\sqrt{2.25} = \pm 1.5\\\sqrt{3.24} = \pm 1.8\\\sqrt{4.41} = \pm 2.1\\\sqrt{5.29} =\pm 2.3[/tex]

Step-by-step explanation:

Given the function:

[tex]y=p(x)=\sqrt{x}[/tex]

That means, the value that we give as input i.e. the value of x is square rooted and given as output.

Input is x and output is [tex]\sqrt x[/tex].

Now, calculating the outputs for different values of x:

1. x = 0, the square root of 0 is always 0.

so, y = p (0) = 0

2. x = 1.44

[tex]y = p(1.44)=\sqrt{1.44} \\\Rightarrow \sqrt{\dfrac{144} {100}}\\\Rightarrow \pm \dfrac{12} {10} = \pm 1.2[/tex]

Similarly other square roots can be calculated:

3.  x = 2.25

[tex]y = p(2.25)=\sqrt{2.25} \\\Rightarrow \sqrt{\dfrac{225} {100}}\\\Rightarrow \pm \dfrac{15} {10} = \pm 1.5[/tex]

4.  x = 3.24

[tex]y = p(3.24)=\sqrt{3.24} \\\Rightarrow \sqrt{\dfrac{324} {100}}\\\Rightarrow \pm \dfrac{18} {10} = \pm 1.8[/tex]

5.  x = 4.41

[tex]y = p(4.41)=\sqrt{4.41} \\\Rightarrow \sqrt{\dfrac{441} {100}}\\\Rightarrow \pm \dfrac{21} {10} = \pm 2.1[/tex]

6.  x = 5.29

[tex]y = p(5.29)=\sqrt{5.29} \\\Rightarrow \sqrt{\dfrac{529} {100}}\\\Rightarrow \pm \dfrac{23} {10} = \pm 2.3[/tex]

Hence, The correct answers are:

[tex]\sqrt{0}=0\\\sqrt{1.44} = \pm 1.2\\\sqrt{2.25} = \pm 1.5\\\sqrt{3.24} = \pm 1.8\\\sqrt{4.41} = \pm 2.1\\\sqrt{5.29} =\pm 2.3[/tex]

Answer:

x = 10.7775

Step-by-step explanation:

We can see that we need to use sin∅ to help solve for x:

sin56° = x/13

13sin56° = x

x = 10.7775

Answer:

10.77

Step-by-step explanation:

Pretty easy stuff, basically you use the sin ratio to solve this.

so it would be sin(56) = x/13

then you multiply 13 to sin(56)

and get 10.77.

I'm guessing the supports in the water are equally distanced. Therefore, I'd divide 168 by four to get a singular distance between two supports. I got 42 yards.

Explanation:

The expression -2x means -2 times x. To undo this, we divide all parts of the inequality by -2. Dividing by a negative number will flip the inequality sign. We go from "less than" to "greater than"

-4 < -2x < 10

-4/(-2) > x > 10/(-2) .... inequality signs flip

2 > x > -5

-5 < x < 2

This unknown number x is between -5 and 2. It cannot equal -5. It cannot equal 2.

Answer:

El tiempo le llevara a Mariano es 2 horas y el tiempo que le llevara a Alberto es de una hora

Step-by-step explanation:

Para calcular el tiempo que le llevará a cada uno si juntos pueden hacer el trabajo en 3h, tenemos que primero segun los datos considerar lo siguiente:

Segun los datos tenemos que Mariano puede despachar periódicos 2 veces el tiempo que le toma a Alberto, por lo tanto:

2X=Mariano puede despachar periódicos 2 veces el tiempo que le toma a Alberto

X=El tiempo que le toma a Alberto.

Por lo tanto calculando la siguiente ecuacion, podremos hallar el valor de X:

2X+X=3 horas

3X=3 horas

X=1 hora

Entonces, tenemos que el tiempo le llevara a Mariano es 2 horas y el tiempo que le llevara a Alberto es de una hora

Answer:

3/10

Step-by-step explanation:

This is mutually exclusive, meaning they cannot happen at the same time, you cannot pickup a marble and it cant be both black and white. So all we do now is just add the probabilities of getting a black marble and white marble

P(picking a black marble) = 2/10

P(picking a white marble) = 1/10

Add them

2/10 + 1/10 = 3/10

Answer:

Option (C). 4.6 cm

Step-by-step explanation:

In the figure attached,

A right triangle has been given with hypotenuse = 6 cm, leg 1 = x cm, leg 2 = y cm and one angle = 50°

By applying Sine rule in this triangle,

Sin(50)° = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}=\frac{\text{Leg 1}}{\text{Hypotenuse}}[/tex]

Sin(50)° = [tex]\frac{x}{6}[/tex]

x = 6(Sin50°)

x = 4.59

x ≈ 4.6 cm

Therefore, Option (C) will be the answer.

The width for maximum area will be 40 metres.

Given,Simon has 160 metres of fencing to build a rectangular garden.

The garden's area (in square meters) as a function of the garden's width x(in meters) is modeled by,

[tex]A(x)=-x(x-80)[/tex].

We know that perimeter of rectangle will be,

[tex]P=2(L+B)\\[/tex]

Here p is 160,

So,[tex]160=2(L+B)[/tex]

[tex]\L+B= 80[/tex]

Now we have the sum of length and width off the rectangular garden is 80.

Since,

[tex]A(x)=-x(x-80)\\[/tex]

So, [tex]A(x)=x(80-x)[/tex]

We know that the area of rectangle will be the product of length and , here in question width is [tex]x[/tex] so the length will be[tex](80-x)[/tex].

Now we have to calculate the width for which the area will be maximum.

The area will be maximum when the first derivative of area function will becomes zero.

So,

[tex]\frac{\mathrm{d} }{\mathrm{d} x} A(x)=\frac{\mathrm{d} }{\mathrm{d} x}(-x)(x-80)[/tex]

[tex]\frac{\mathrm{d} }{\mathrm{d} x}A(x)=\frac{\mathrm{d} }{\mathrm{d} x}(-x^{2} +80x)[/tex]

[tex]\frac{\mathrm{d} }{\mathrm{d} x}A(x)=-2x+80\\[/tex]

For maximum area ,

[tex]\frac{\mathrm{d} }{\mathrm{d} x}A(x)=0[/tex]

Hence,

[tex]-2x+80=0\\x=40[/tex]

Hence the width for maximum area will be 40 metres.

https://brainly.com/question/16545343

The maximum area is 1600 sq meters.

The garden's area is modeled by a quadratic function, whose graph is a parabola.

The maximum area is reached at the vertex.

So in order to find the maximum area, we need to find the vertex's y-coordinate.

We will start by finding the vertex's x-coordinate, and then plug that into A(x).

The vertex's x-coordinate is the average of the two zeros, so let's find those first.

A(x)=0    -x(x-80)=0

  ↓                  ↓

-x=0 or x-80=0

x=0 or x=80

Now let's take the zeros' average:

[tex]\frac{(0)+(80)}{2}=\frac{80}{2}=40[/tex]

The vertex's x-coordinate is 40. Now lets find A(40):

A(40)= -(40)(40-80)

        = -(40)(-40)

        = 1600

in conclusion, the maximum area is 1600 square meters.

Answer:

b = sqrt(45)

Step-by-step explanation:

This is a right triangle, so we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and be are the legs and c is the hypotenuse

2^2 + b^2 = 7^2

4 + b^2 = 49

Subtract 4 from each side

b^2 = 49-4

b^2 = 45

Take the square root of each side

sqrt(b^2) = sqrt(45)

b = sqrt(45)

Answer:

Option (3)

Step-by-step explanation:

We have to divide polynomial given as (x³ - 21x² + 147x - 343) by (x - 7) by synthetic division.

7 | 1     -21     147      -343

  ↓       7     -98        343

    1     -14      49          0

Therefore, quotient is (x² - 14x + 49) and the remainder will be 0.

Option (3) will be the answer.

40% of the student in a class are female. if there are 10 females in the class, how many males are there in the class

Answer:

15 males

The total no. of males in a class is 15.

To find the no. of males.

science that deals with the addition, subtraction, multiplication, and division of numbers and properties and manipulation of numbers.

Given that:

If females are 40% , % of males =100-40=60%.

Let the total no. of students be x.

No. of girls = 40% of x

10= (40/100) * x

x=(10*100)/40

x= 25

total no. of students =25

Total no. of males = 60% of x

=(60/100)* 25

=15

So, total no. of males in a class is 15.

Multiply 1/2 by 2 to get 1 and multiply 14 by 2 so the ratio is equal

1/2 x 2 = 1

14 x 2 = 28

so 1 = 28

Multiply everything 28

3/14 x 28 = 84/14 = 6/1 = 6

1/14 x 28 = 28/14 or 2

5/7 x 28 140/7 = 20

3/7 x 28 = 84/7 = 12

2/7 x 28 = 56/7 = 8

1/7 x 28 = 28/7 = 4

3/4 x 28 = 84/4 = 21

1/4 x 28 = 28/4 = 7

Answer:

[tex]T_{10} - T_7 = 112[/tex]

Step-by-step explanation:

Given

[tex]T_9 = 63[/tex]

Required

Find [tex]T_{10} - T_7[/tex]

From the question, we have that:

Each sequence = 2 * Previous sequence + 1;

i.e.

[tex]T_n = 2 * T_{n - 1} + 1[/tex]

Considering the 9th sequence;

[tex]T_9 = 2 * T_8 + 1[/tex] ------ Equation 1

Considering the 8th sequence;

[tex]T_8 = 2 * T_7 + 1[/tex]

Substitute [tex]2 * T_7 + 1[/tex] for [tex]T_8[/tex] in equation 1

[tex]T_9 = 2 * T_8 + 1[/tex] becomes

[tex]T_9 = 2 * (2 * T_7 + 1) + 1[/tex]

Open bracket

[tex]T_9 = 2 * 2 * T_7 + 2*1 + 1[/tex]

[tex]T_9 = 4T_7 + 2 + 1[/tex]

[tex]T_9 = 4T_7 + 3[/tex]

Substitute 63 for [tex]T_9[/tex]

[tex]63 = 4T_7 + 3[/tex]

Subtract 3 from both sides

[tex]63 - 3 = 4T_3 + 3 - 3[/tex]

[tex]60 = 4T_3[/tex]

Divide both sides by 4

[tex]\frac{60}{4} = \frac{4T_3}{4}[/tex]

[tex]15 = T_7[/tex]

[tex]T_7 = 15[/tex]

Considering [tex]T_{10}[/tex]

[tex]T_1_0 = 2 * T_9 + 1[/tex]

Substitute 63 for [tex]T_9[/tex]

[tex]T_1_0 = 2 * 63 + 1[/tex]

[tex]T_1_0 = 126 + 1[/tex]

[tex]T_1_0 = 127[/tex]

Calculating [tex]T_{10} - T_7[/tex]

[tex]T_{10} - T_7 = 127 - 15[/tex]

[tex]T_{10} - T_7 = 112[/tex]

Hence, the 10th - 7th number is 112
