Answer 1

Answer:

0.69

Step-by-step explanation:

In a right triangle, the cosine of one of the acute angles is the ratio of the adjacent ("next to") side to the hypotenuse.

In this triangle, the side adjacent to angle T has length [tex]\sqrt{38}[/tex].  Now you need the length of the hypotenuse, ST.  Use the Pythagorean Theorem:

[tex]ST^2=(\sqrt{38})^2+(\sqrt{41})^2 \\\\ST^2=38+41\\\\ST=\sqrt{79}[/tex]

Build the ratio (adjacent) / (hypotenuse) and approximate it with a decimal.

[tex]\cos{T}=\frac{\sqrt{38}}{\sqrt{79}} \approx 0.69[/tex]

Answer 2

[tex]{\large{\red{\mapsto{\maltese{\underline{\green{\boxed{\blue{\underbrace{\overbrace{\pink{\pmb{\bf{Answer:}}}}}}}}}}}}}}[/tex]

To find :-

Cos T = ?

Given :-

Perpendicular(P) = RS = √41

Base(B) = RT = √38

Formula to be used :-

We will use here a trignometry formula to find hypotenuse (H) which is ST.

(hypotenuse)² = (perpendicular)² + (base)²

[tex] \cos(A) = \frac{base}{hypotenuse} [/tex]

Solution:-

H² = P² + B²

H² = (√41)² + (√38)²

H² = 41 + 38

H² = 79

H = √79

[tex] \cos(T) = \frac{B}{H} \\ \cos(T) = \frac{ \sqrt{38} }{ \sqrt{79} } \\ \cos(T) = \frac{6.17}{8.89} \\ \cos(T) = 0.69[/tex]

Result :-

The value of cos(T) is 0.69.

The quotient of the provided division in which binomial is divided by a quadratic equation is x+2.

What is the quotient?

Quotient is the resultant number which is obtained by dividing a number with another. Let a number a is divided by number b. Then the quotient of these two number will be,

[tex]q=\dfrac{a}{b}[/tex]

Here, (a, b) are the real numbers.

The given division expression is,

[tex]\dfrac{x^2+3x+2}{x+1}[/tex]

Let the quotient of this division problem is f(x). Thus,

[tex]f(x)=\dfrac{x^2+3x+2}{x+1}[/tex]

Factor the numerator expression as,

[tex]f(x)=\dfrac{x^2+2x+x+2}{x+1}\\f(x)=\dfrac{x(x+2)+1(x+2)}{x+1}\\f(x)=\dfrac{(x+2)(x+1)}{x+1}\\f(x)={x+2}[/tex]

Which equation represents a circle with a center at (–4, 9) and a diameter of 10 units? (x – 9)2 (y 4)2 = 25 (x 4)2 (y – 9)2 = 25 (x – 9)2 (y 4)2 = 100 (x 4)2 (y – 9)2 = 100

Answers

The circle can be illustrated by its equation, and the equation that represents the circle is (x + 4)² + (y - 9)² = 5²

How to determine the circle equation?

The center of the circle is given as:

Center, (a,b) = (-4,9)

The diameter is given as:

d = 10

Calculate the radius (r)

r = 10/2 = 5

The circle equation is then calculated using:

(x - a)² + (y - b)² = r²

So, we have:

(x + 4)² + (y - 9)² = 5²

Hence, the equation that represents the circle is (x + 4)² + (y - 9)² = 5²

Step-by-step explanation:

Let x = number of hours worked

Let y = profit earned

Profit is the amount left after expenses are deducted.

Given:

Terry earns $30 per hour walking dogs

⇒ y = 30x

Given:

Terry pays $150 each month to a grooming service

This is Terry's expenses, so we must deduct this amount from the amount he earns walking the dogs to calculate the final profit:

Tye has a square piece of yellow felt that has an area of 81 square inches. She wants to cut the largest circle possible from the material to create a sun for her art project. What is the area of the felt circle? Use 3.14 for π. Round to the nearest hundredth if necessary.

Answers

Answer:

63.59 in²

Step-by-step explanation:

The formula to find the area of a square: a², where a is the side.

The formula to find the area of a circle: πr², where r is the radius (diameter ÷ 2), and the pi is alterable (3.14 or 3.142 or 22/7).

1) Find the diameter of the circle. The side of a square is the diameter.

a = √81

a = 9

2) Plug the values into the formula of the area of a circle. 9 ÷ 2 = 4.5 (radius).

= 3.14 x 4.5²

= 3.14 x 20.25

= 63.585

3) Round off the result to the nearest hundredth.

= 63.59

The largest circle possible from the square piece of yellow felt material to create a sun for her art project is of area 63.585 square inches.

What is area?

Area is the quantity that expresses the extent of a region on the plane or on a curved surface

According to the question

Square piece of yellow felt that has an area = 81 square inches

Now ,

Area of square of yellow felt =  81 square inches

⇒     [tex]Side^{2} = 81[/tex]

⇒      Side = ± 9      (where -ve 9 cannot be side )

⇒      Side =  9      

 

The largest circle possible from the material is

where, side of square = diameter of circle  ( figure attached )

        ⇒  9   = diameter of circle

       ⇒   9 = 2r

       ⇒   [tex]\frac{9}{2}[/tex] = r or  r = 4.5

Area of circle = [tex]\pi r^{2}[/tex]

                      =  3.14 * 4.5 * 4.5

                     = 63.585 square inches.

Hence, Area of the largest circle cut from the  square piece is of 63.585 square inches.

Sharon is jumping from an 18-foot diving board with an initial upward velocity of 4 ft/s. when sharon jumps, megan throws a beach ball up to sharon with an initial upward velocity of 16 ft/s from a height 5 feet off the ground. to the nearest hundredth of a second, how long after she jumps does the ball reach sharon? 0.65 seconds 0.92 seconds 1.08 seconds 1.15 seconds

Answers

It will take 1.08 seconds for the ball to reach Sharon after she jumps if the upward velocity of the ball is 16 ft/s from a height of 5 feet option third is correct.

What is the equation of motion?

It is defined as the equation by which we can find the motion of a physical particle with respect to time. It is the representation of physical entity movement in a mathematical function.

We have:

The height of the Sharon from the diving board = 18 feet

The initial upward velocity of the Sharon = 4 ft/s

The height of the Megan from the ground = 5 feet

The initial upward velocity of the beach ball = 16 ft/s

We know the equation of motion is given by:

[tex]\rm h(t) = x + ut+\frac{1}{2} gt^2[/tex]

Put x = 18 feet and u = 4 ft/s in the above equation, we get:

[tex]\rm h(t) = 18 + 4t+\frac{1}{2} \times9.8t^2[/tex] ....(1)     [g = 9.8 m/s²]

Put x = 5 feet and u = 16 ft/s in the equation of motion, we get:

[tex]\rm h(t) = 5 + 16t+\frac{1}{2} \times9.8t^2[/tex]  ....(2)

Equate the equation (1) and equation (2), we get

[tex]\rm 18 + 4t+\frac{1}{2} \times9.8t^2= 5 + 16t+\frac{1}{2} \times9.8t^2\\[/tex]

18 + 4t = 5 + 16t

12t = 13

t = 1.08 seconds

Thus, it will take 1.08 seconds for the ball to reach Sharon after she jumps if the upward velocity of the ball is 16 ft/s from a height of 5 feet.

OD. The principal surveys all the students in the math club.​

Answers

Answer:

C. The principal randomly selects homeroom classes and surveys each student in the chosen classes.

Step-by-step explanation:

Middle school is 6-8th. Surveying only the eighth-grade students won't give a representative sample of the whole school only the eighth-graders. Option A is incorrect.

Surveying only the students in detention represents a very small amount of students compared to the school, therefore it is not a representative sample. Option B is incorrect.

Yet again, the students in the math club is a small amount of students compared to the school. It does not represent the entire, or majority of the population. Option D is incorrect.

Picking students from homeroom classes and surveying each will give a wider variation of opinions from each grade and therefore a representative sample. Option C is the correct answer.

To recall trigonometric ratios, there is a special acronym known as sohcahtoa which stands for

sin(x)=opposite/ hypotenusecos(x)=adjacent/hypotenuse tan(x)=opposite /hypotenuse

Finding the angle [tex]\theta[/tex]

We are given that,

[tex] \displaystyle \sin( \theta) = \frac{ \sqrt{3} }{2} [/tex]

To find the angle [tex]\theta[/tex] , take inverse of sin of both sides,

[tex] \displaystyle { \sin}^{ - 1}( \sin( \theta) )= { \sin}^{ - 1} \bigg(\frac{ \sqrt{3} }{2} \bigg )[/tex]

with the help of unit circle,we acquire:

[tex] \displaystyle \boxed{\theta= {60}^{ \circ} }[/tex]

Finding [tex]\tan\theta[/tex]

simply plug in the value of theta:

[tex] \tan( {60}^{ \circ} ) [/tex]

using unit circle,we get:

[tex] \implies \tan( {60}^{ \circ} ) = \boxed{\sqrt{3} }[/tex]

and we're done!

Let's solve

[tex]\\ \rm\Rrightarrow sin\theta=\dfrac{\sqrt{3}}{2}[/tex]

[tex]\\ \rm\Rrightarrow \theta=sin^{-1}\left(\dfrac{\sqrt{3}}{2}\right)[/tex]

[tex]\\ \rm\Rrightarrow \theta=\dfrac{\pi}{3}[/tex]

Now

[tex]\\ \rm\Rrightarrow tan\theta=tan\dfrac{\pi}{3}[/tex]
