Se va a colocar una escalera que mide 5 metros (m) de longitud sobre una pared. El fabricante de la escalera recomienda que, por seguridad, el ángulo que forme la escalera con el piso sea de 78°, ¿Cuál será la distancia sobre el piso del pie de la escalera a la pared?

Answers

Answer 1

Answer:

4.9 m

Step-by-step explanation:

Resolvemos la pregunta anterior usando la función trigonométrica de seno

sin θ = Opuesto / Hipotenusa

θ = 78 °

Hipotenusa = Longitud de la escalera = 5 m

Opuesto = Distancia sobre el suelo = x

sin 78 = x / 5m

Multiplicar cruzada

x = sin 78 × 5 m

x = 4.8907380037m

Aproximadamente

= 4.9 m

What type of conic section is represented by the parametric equations below? X=3cos(t)-1 y=3sin(t)+4

Answers

Answer:

Circle

Step-by-step explanation:

Examples of conic sections are the circle, the ellipse, the parabola and the hyperbola. Parametric equations are used to express the x and y variables in terms of a less complicated manner using a third variable (t or θ).

The parametric equation for a circle with an equation [tex](x-h)^2+(y-k)^2=r^2[/tex] is given by:

[tex]x=rcos(t)+h, y=rsin(t)+k[/tex]

where r is the radius of the circle and (h, k) is the center of the circle.

A conic section with a parametric equations X=3cos(t)-1, y=3sin(t)+4 is a circle with center at (-1, 4) and radius of 3. The equation of the circle is:

(x + 1)² + (y - 4)² = 3²

why is probability limited to numbers between 0 and 1​

Answers

Answer:

Probability by definition is the extent to which an event is likely to occur, measured by the ratio of the favourable cases to the whole number of cases possible.

Since number of elements in the set of favourable cases is less than or equal to the number of elements in the set of whole number of cases, their ratio would always end up being 1 or less than one.

Probability equals one when favourable number of cases are same as that of the whole number of cases and probability equals zero when there is no favourable case

a. What is the common multiplier?
b. What is the zeroth term?
c. What is the value of the 25th term t(25)?

Answers

Answer: See explanation

Step-by-step explanation:

a. What is the common multiplier?

This will be gotten by dividing the second term by the first term. This will be:

= 49/70 = 0.7

Common multiplier = 7/10 or 0.7

b. What is the zeroth term?.

a = 70

The zeroth term is 70

c. What is the value of the 25th term t(25)?

nth term = ar^n-1

25th term = ar^25-1

= ar^24

= 70 × 0.7^24

= 70 × 0.0001916

= 0.013412

What is the equation of a circle with a center located at (4, -1) and a radius of 9?

Answers

Answer:

(x-4)^2 + (y+1)^2 = 81

Step-by-step explanation:

you clearly have internet access and could have very quickly searched for the equation of a circle.

(x-h)^2 + (y-k)^2 = r^2

with (h,k) being the center.

=> (x-4)^2 + (y+1)^2 = 81

Jenny bought 3 CDs that were each the same price. Including sales tax, she paid a total of $45.30 Of that total, $1.50 was tax. What was the price of each CD before tax?
I need the right answer give brainliest

Answers

Answer:

$13.6

Step-by-step explanation:

Jane bought 3 CDs that were each the same price. So let the price of each CD be ‘x’.

It is given that including sales tax, she paid a total of $45.30.

Also each CD had a tax of $1.50. We need to find out what the price of each CD was before tax.

Since the tax for all 3 CDs was same, the total amount of tax that she paid was:

3 * 1.50 = 4.50

Therefore the total tax on 3 CDs is $4.50

Since we already know the total price she paid for the CDs including taxes, we can find the price of each CD by the following way:

3x + 4.50 = 45.30

3x = 45.30 - 4.50

3x = 40.8

x = 13.6

Therefore the price of each CD before tax is $13.6.

A rectangle has a length of 14 yards less than 9 times its width. If the area of the rectangle is 6183 square yards, find the length of the rectangle.

Answers

Answer:

 [tex]l=238\ yards[/tex]

Step-by-step explanation:

From the question we are told that:

Area of Rectangle A=6183

Equation of Length

 [tex]l=9w-14[/tex]

Where

[tex]w=width\ of\ triangle[/tex]

Generally the equation for Area of Rectangle is mathematically given by

 [tex]A=(9w-14)w[/tex]

 [tex]A=9w^2-14w[/tex]

 [tex]6183=9w^2-14w[/tex]

 [tex]9w^2-14w-6183=0[/tex]

 [tex]w=28[/tex]

Therefore

 [tex]l=9(28)-14[/tex]

 [tex]l=238\ yards[/tex]

Answer:

116

Step-by-step explanation:

a line is 180 degrees so subtract 64 and you get 116, that is your angle

Given: these two lines are parrallel cut by a transversal, 4 is 64 degrees

because 4 is given we know 6 is also 64 becasue they are alternative interior angles

all straight lines measure to 180 degrees so 3 and 5 become 116 because 180-64=116 (we also know these lines are parallel becasue 4 and 5 are supplementary, they add up to 180 as well.)

becasue 5 is 116 8 needs to be 64 and becasue 8 is 64 to equal 180 7 needs to be 116 (again, they need to add up to 180 becasue they are a straight line)

Out of the total students in a class, if the number of boys is 5 and the number of girls being 3, then find the ratio between girls and boys.​

Answers

Answer:

3:5

Step-by-step explanation:

The ratio between girls and boys is 3:5  ...   there are 3 girls for each set of 5 boys.

The ratio between girls and boys is 3 : 5 in the class.

What is the ratio?

The ratio is defined as a relationship between two quantities, it is expressed one divided by the other.

What are Arithmetic operations?

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

Given data as :

The number of boys in the class = 5 and

The number of girls in the class = 3,

So, total the total students in a class = 5 + 3 = 8

The ratio between girls and boys as : number of girls  / number of boys

The ratio between girls and boys = 3 / 5

Hence, the ratio between girls and boys is 3 : 5 in the class.

HELPPPPPP PLEASE Jerrod's mountain bike has a tire diameter of 26 inches, How far will the
bike travel in 100 rotations of its tires?

Answers

Answer:

Step-by-step explanation:

The process here is to find out how far the tire travels in one rotation, then multiply that by 100. That means we need to find the circumference of the tire since the circumference tells us how far around the outside of the tire it is in inches.

C = πd where d is the diameter of the tire.

C = 3.1415(26) so

C = 81.679 inches. Multiply that by 100 to get

8167.9 inches, which in miles is a little over 1.5 miles

Answer:

16/3

Step-by-step explanation:

When dividing by a fraction, you can multiply by its reciprocal.

This can be remembered easily using the mnemonic "keep, change, flip" where you keep the first fraction (in this case, 3/1), change the sign of the operator (from division to multiplication) and flip the second fraction (in this case 1/4 into 4/1). Thus 3 / 1/4 = 3/1 x 4/1 = 12/1 = 12

Answer:

See explanation below

Step-by-step explanation:

3 divided by 1/4 equals 12

Flip 1/4 to get 4, then multiply that by 3 to get 12.

4 divided by 3/4 = 16/3

Flip 3/4 to get 4/3, then multiply that by 4 to get 16/3
