In the early spring, the trout at Big Blue Lake swim at a depth of 30 feet below sea level.
When the lake warms up in the summer, the trout swim 20 feet deeper than that.
At what position relative to sea level do the trout swim in the summer?

Answers

Answer 1

Given :

In the early spring, the trout at Big Blue Lake swim at a depth of 30 feet below sea level.

When the lake warms up in the summer, the trout swim 20 feet deeper than that , d = 20 feet .

To Find :

At what position relative to sea level do the trout swim in the summer.

Solution :

Depth in spring from surface , [tex]D_s=30\ feet[/tex] .

Let , depth in summer is D .

Now , depth in summer relative to sea-level is :

[tex]D=D_s+d\\\\D=30+20\ feet\\\\D=50\ feet[/tex]

Therefore , trout swim 50 feet deep below the sea level in the summer .

Hence , this is the required solution .

Select the correct answer from each drop-down menu.

cos2x-cos4x/sin2x+sin4x = tan x

cos2x+cos4x/sin2x-sin4x  = -cot x

The trigonometric equations have value tan x, -cot x .

What is a Trigonometric Ratios?

Trigonometric Ratios are ratios of the side of a right angled triangle. These are used to find the missing sides and angles of a right angled triangle.

The trigonometric equation is

(cos 2x - cos 4x )/(sin2x +sin4x)

cos A + cos B =  - sin (A+B)/2 sin(A-B)/2

sin A - sin B = sin( A+B)/2 cos (A-B)/2

= (-sin 3x) sin ( -2x)/2)/( cos 3x cosx)

= sin 3x sin x/ (sin 3x) cos x

= tan x

The other equation is

(cos 2x +cos 4x)/(sin 2x- sin4x)

=  cos 3x cosx/ cos3x sin(- x)

= - cot x

NO is an angle bisector. Solve for x.

A. x = -10
B. Not enough information
C. x = 10
D. x = 4

Answers

Answer:
x= -10

Explanation:

When solving for x with 2 equations given, you’d add 3x+10 with 7x-30 like so: 3x+10=7x-30. you ALWAYS work your way from right to left till you’ve got nothing on your right but a number with no variable, so subtract 7x with 3x, giving you 4x, so now your equation would be: 4x+10=-30. Now that there is a single number to the right, you start to rotate, so subtract 10 from -30, giving you -40, so now your equation would be: 4x=-40. This is the last step, so all you have to do is divide 4x to itself and to -40. You DO NOT add the variable x to your answer, so it should be: x=-10 as your final answer.

Answers

An estimation is made by slightly rounding the numbers, then multiplying , adding, subtracting, or dividing.
In this case , to make an estimate, I would round 114 to 100, and 92 to 90... 100 x 90 = 9,000 sq in
You can of course round closer than that, depending on how accurate you want it to be, but the exact answer is 10,488, Wich you can round to 10,000 or 10,500

Step-by-step explanation:

The distance of Becky from the school is 10 blocks.

What is Pythagoras's theorem?

Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

We have been given that Becky leaves school to go home. She walks 6 blocks North and then 8 blocks west.

According to the given situation, we can plot the diagram which has been attached below.

As per the figure, we have a right triangle that has :

AB = 8 blocks, and BC = 6 blocks

The distance of Becky from the school is equal to the length of AC.

By Pythagoras's theorem,

AC² = AB² + BC²

AC² = 8² + 6²

AC² = 64 + 36

AC² = 100

AC = 10 blocks

Therefore, the distance of Becky from the school is 10 blocks.

HELP!!!!Find the measurement of 4(Explain)

Answers

Answer:

26°

Step-by-step explanation:

The angle 5 is equal to angle 154° as these are both corresponding angles and corresponding angles are equal.

Angles on a straight line equal 180°, so if we take 154° from 180° we get angle 4, which is 26°

I hope that helped!

SoluTion-

XY and WZ are parallel.

Angle 1 + 154° = 180° (Linear pair)

→ Angle 1 = 180 - 154

→ Angle 1 = 26°

Now, Angle 4 = Angle 1 (Alternative interior angles)

→ Angle 4 = 26°

Hence, we got the answer.

Answers

Answer:

C. 30

Step-by-step explanation:

Distance formula - [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}[/tex]

The scale factor of 7 is basically saying that the coordinates (3,4) are going to be increased 7 times.

3•7 = 21=x         --> A prime = (21,28)

4•7 = 28=y

[tex]\sqrt{(21-3)^2+(28-4)^2}[/tex]

= [tex]\sqrt{324+676}[/tex]

= [tex]\sqrt{900}[/tex]

Step-by-step explanation:

Use the given endpoint Y and the midpoint M of YZ (there is a line over YZ) to find the coordinates of the other endpoint Z

Answers

The x-coordinate of our midpoint = 3

The x-coordinate of Y = 0

k  = x-coordinate of Z

3 = (0 + k) / 2

Multiply both sides by 2

6 = k + 0

Simplify

6 = k

The y-coordinate of our midpoint = 3

the y-coordinate of Y = 5

w = y-coordinate of Z

3 = (w + 5) / 2

Multiply both sides by 2

6 = w + 5

Subtract 5 from both sides

1 = w

For problem #17, Z(6, 1)

Let's do problem 18 now.

The x-coordinate of our midpoint = 5

The x-coordinate of Y = -1

k = x-coordinate of Z

5 = (k + (-1)) / 2

Multiply both sides by 2

10 = k + (-1)

Simplify the right side

10 = k - 1

Add 1 to both sides

11 = k

The y-coordinate of our midpoint = 9

The y-coordinate of Y = -3

w = y-coordinate of Z

9 = (w + (-3)) / 2

Multiply both sides by 2

18 = w + (-3)

Simplify the right side

18 = w - 3

Add 3 to both sides

21 = w

For problem #18, Z(11, 21)

Answers

Answer:

Step-by-step explanation:

y=3x-14

standard  form : 3x-y=14 ( move variable together on one side )

convert y-6=-1/3 (x-9) to standard form :

first : y-6 = -1/3 x -1/3(-9)

y-6=-1/3 x +9/3

y-6=-1/3x+3

y+1/3x =3+6

y+1/3x=9 ( common denominator)

(3y+x)/3=9 ( cross multiplication)

3y+x=3(9)

3y+x=27

Convert 3x+y=9 (standard form) to slope intercept form (y=mx+b)
