Answer:

your perimeter will be 40cm

The 4 sides of a square are the same length. Find the length of a side by taking the square root of the area.

Side = sqrt(100) = 10 cm

Perimeter = side length x 4

Perimeter = 10 x 4 = 40 cm

The distance of the boat from the base of the cliff is 114 feet.

There are three commonly used trigonometric identities.

Sin x = 1/ cosec x

Cos x = 1/ sec x

Tan x = 1/ cot x or sin x / cos x

Cot x = cos x / sin x

We have,

Cliff ________________

       \  ) 35°                       |

          \                              |

              \                          |  ( 80 feet )

                                     \  Boat

     ← ______x________→

(distance of the boat from the base of the cliff)

Now,

tan 35 = 80/x

0.7 = 80/x

x = 80/0.7

x = 114 feet

Thus,

The distance of the boat from the base of the cliff is 114 feet.

Answer:

D. 5 for x less than or equal to 4, equals 2x for x between 4 and 6 including 6, and equals 4 for x greater than 6 Domain: All real numbers.

Step-by-step explanation:

Find the complete diagram attached

First we need to get the derivative of the functions

For the function f(x) = 5x - 6

Using the formula

If f(x) = axⁿ

f'(x) = naxⁿ⁻¹

For the function f(x) = 5x - 6

f'(x) = 1(5)x¹⁻¹

f'(x) = 5x⁰

f'(x) = 5

For the function f(x) =x²-2

f'(x) = 2x²⁻¹

f'(x) = 2x

For the function f(x) = 4x+10

f'(x) = 1(4)x¹⁻¹

f'(x) = 4x⁰

f'(x) = 4

Get the domain

The domain is the value of the input variable x for which the functions exists. For the functions given, the domain will be on all real numbers i.e the functions will exists for any value of x on the number line.

[tex]\dfrac{96}{40}[/tex] and [tex]\dfrac{120}{50}[/tex]

Step-by-step explanation:

24 kernels in 10 minutes

In 1 minute she can eat [tex]\dfrac{24}{10}=\dfrac{12}{5}\ \text{kernels}[/tex]

let [tex]x[/tex] be the number of popcorn and minutes so the rate of eating popcorn is of the form

[tex]\dfrac{x12}{x5}[/tex]

So, when [tex]x = 6[/tex] we get

[tex]\dfrac{6\times12}{6\times 5}=\dfrac{72\ \text{kernels}}{30\ \text{minutes}}[/tex]

[tex]x[/tex] can be any real number

[tex]\dfrac{10\times 12}{10\times 5}=\dfrac{120\ \text{kernels}}{50\ \text{minutes}}[/tex]

[tex]\dfrac{8\times 12}{8\times 5}=\dfrac{96\ \text{kernels}}{40\ \text{minutes}}[/tex]

Other two ratios can be [tex]\dfrac{96}{40}[/tex] and [tex]\dfrac{120}{50}[/tex].

Answer:

0.033 pounds/min

Step-by-step explanation:

For Meagen:

Time taken to cook golden turkey = 56 minutes

Weight of golden turkey = 12 pounds

For her competitor:

Time taken to cook golden turkey = 1 hour 16 minutes = 77 minutes

Weight of golden turkey = 304 ounces

16 ounces = 1 pound

Therefore, 304 ounces = [tex]\frac{304}{16}[/tex] = 19 pounds

Now, let us find the number of pounds cooked per minute by each chef.

Pounds cooked per minute by Meagen = [tex]\frac{12}{56} = 0.214\ pounds/min[/tex]

Pounds cooked per minute by the competitor = [tex]\frac{19}{77} = 0.247\ pounds/min[/tex]

Difference = 0.247 - 0.214 = 0.033 pounds/min

Answer:

y  = 3

Step-by-step explanation:

P ( 1 , 3)    and  Q ( 3 , 3 )

The straight line is parallel to the x-axis since the two points have the same y.

The intercept with the y-axis is 3.

The slope-point equation for a line is:

y  = m*x + b             (1)

m is the slope and  b is the intercept with the y-axis

To calculate the slope

m =  (  y₂ -  y₁ ) /  ( x₂  -  x₁ )

m =  3 - 3 / 3 - 1          m   = 0 / 2      m  = 0

therefore, equatio (1) becomes

y  =  0*x + 3

y  = 3

Step-by-step explanation:

The greatest possible whole-number length of the unknown side among the option is 9 inches.

Obtuse triangle is a triangle that has one of it internal angle greater than 90 degrees.

The sum of the lengths of any two sides of a triangle is greater than the length of the third side.

If the sides of the triangles are x, y and z. Therefore,

x + y > z

x + z > y

y + z > x

Therefore, the greatest possible length among the option is 9.

Proof

12 + 14 > 9

12 + 9 > 14

14 + 9 > 12

Answer:

y = -3x + 7

Step-by-step explanation:

Again, pick a random point. I chose point (0,7). Then, we see how many units it takes to reach the next point. Let's try it. First, we move down 3 units, rise = -3, then move right 1 unit, run 1. So slope is rise over run, so -3/1 = -3. Then, for the y intercept, just see the y value when x = 0.

Answer:

y = - 3x + 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 7) and (x₂, y₂ ) = (2, 1) ← 2 points on the line

m = [tex]\frac{1-7}{2-0}[/tex] = [tex]\frac{-6}{2}[/tex] = - 3

The line crosses the y- axis at (0, 7 ) ⇒ c = 7

y = - 3x + 7 ← equation of line

Answer:

The answer is C: (-9,1) and (5,1). took the test. Good luck!

Step-by-step explanation:

The coordinates of the vertices that lie on the major axis of the conic section can be written as (5,1) and (-9,1), so option C is correct.

A formula known as an equation uses the equals sign to denote the equality of two expressions.

Given equation:

(x + 2)² / 49 + (y - 1)² / 25 = 1

The above equation can be simplified as,

(x + 2)² / 7² + (y - 1)² / 5² = 1

The left side has to be equal to 1, the (x + 2)² / 7² the term has to be equivalent to 1, and the term (y - 1)² / 5² to be equivalent to zero

(y - 1)² / 5² = 0, y - 1 = 0, y = 1

(x + 2)² / 7² = 1

(x + 2)² = 49

(x + 2) = ±7

x = +7 - 2 = 5

x = -7 - 2 = -9

Therefore, the coordinates of the vertices that lie on the major axis of the conic section can be written as (5,1) and (-9,1).
