The ladder will be safe at this height .

There are six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec). In geometry, trigonometry is a branch of mathematics that deals with the sides and angles of a right-angled triangle. Therefore, trig ratios are evaluated with respect to sides and angles.

According to question

Sandy has a ladder whose length = 16.5 feet

He wants to lean the ladder against a vertical wall  15.9 feet above the ground.

And he wants the angle the ladder makes with the

ground to be < 76°.

As Perpendicular = 15.9 feet

and Hypotenuse = 16.5

Sin Ф = [tex]\frac{Perpendicular }{Hypotenuse}[/tex]

Sin Ф = [tex]\frac{15.9}{16.5}[/tex]  

Sin Ф = 0.9636

Therefore,  Ф  ≈ 74.49 (approx.)

That means it is safe .

Hence, The ladder will be safe at this height as it is not greater than 76° .

Step-by-step explanation:

1) Add all of the origanal visitors (376)

2) Find the ratio (28/376) = 0.0744

3) Either 28/376 * 600 OR 0.0744 * 600 (I would recomend the fraction for more accurate answers, but because it says to round to the nearest whole number either will work, but you should still use fraction)

4) 44.6908

5) Round to 45 people

The approximate value of the speed of the car in feet per second is A. 5.32 ft/s.

An equation is an expression that shows the relationship between two or more numbers and variables. In this case, tan(θ) = s² / 49

sinθ = 1/2

θ = sin⁻¹ (0.5) = 30⁰

tan(30) = s² / 49

s = 5.32 ft/s

Therefore, the approximate value of the speed of the car in feet per second is 5.32 ft/s.

Answer:

Option A

Step-by-step explanation:

Area of shaded region

Square:

   Side = 12 m

Area of square = Side *side

                        = 12 *12

                         = 144 square m

Circle:

  diameter = side of the square

                  = 12 m

             r    = 12/2

                r = 6 m

  Area of circle = πr²

                         = 3.14 *6 * 6

                         = 113.04 m²

Area of the shaded part = area of square - area of circle

                                        = 144 - 113.04

                                        = 30.96 m²

Answer:

I beleive the fist one is.

Step-by-step explanation:

The first one is a possibility, the second has a correlaition, and the third, I believe is a correlation.

Quadrilateral KLMN has vertices K(-2,-2), L(1,1), M(0,4), and N(-3,5)

It is first translated by (x + 2,y - 1)

then

K(-2,-2) ---> K'(-2 + 2,-2 - 1) = (0,-3)

L(1,1), ---> L'(1 + 2,1 - 1) = (3,0)

M(0,4), ---> M' (0 + 2,4 - 1) = (2,3)

and

N(-3,5) ---> N' (-3 + 2,5 - 1) = (-1,4)

and then translated by (x - 3,y + 4)

K'(0,-3) ---> K''(0 - 3,-3 + 4) = (-3,1)

L'(3,0) ---> L''(3 - 3,0 + 4)= (0,4)

M'(2,3)  ---> M'' (2 - 3, 3 + 4)= (-1,7)

and

N'(-1,4) ---> N'' (-1 - 3,4 + 4) = (-4,8)

the coordinates of K" L" M" N" after both translations are

K''= (-3,1)

L''= (0,4)

M''= (-1,7)

and

N'' = (-4,8)

To represent the linear function in order for the data the value of a=18.

In calculus and related areas, a linear function is a function whose graph is a straight line, that is, a polynomial function of degree zero or one.

It is given that for a linear function the value is changing at the rate of 5 so we can see in the table as the function independent value is changing then the value of the dependent linear function increases by 5.

So the value of a will be equal to 18.To represent the linear function in order for the data the value of a=18.

[tex]circumference = 2 \times \pi \times r[/tex]

[tex]circumference = 2 \times \pi \times 7[/tex]

[tex]circumference = 14\pi[/tex]

Answer:

14π

Step-by-step explanation:

Given:

To determine the circumference of the circle, we need to use the formula 2πr, where "r" represents the radius of the circle.

Substitute the radius in the formula:

[tex]\implies 2\pi (r) = \text{Circumference}[/tex]

[tex]\implies 2\pi (7) = \text{Circumference}[/tex]

Simplify the circumference:

[tex]\implies 2\pi (7) = \text{Circumference}[/tex]

[tex]\implies 14\pi = \text{Circumference}[/tex]

Thus, the circumference is 14π.
