Answer:

x=3

Step-by-step explanation:

In the equation , it take 2 hours for the experienced crew to paint the apartment.

What is equation?

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

Here let us take x as time taken by new crew of painters apartment and y as time taken by experienced crew of painters apartment .

Now a new crew of painters takes two times as long to paint a small apartment as the experienced crew  then,

x = 2y ----> 1

both crews can paint the apartment in 6 hours then,

=> x+y = 6

Now put  equation 1  into x+y=6 then,

=> 2y+y=6

=> 3y = 6

=> y = 6/3 = 2 hours.

Hence it take 2 hours for the experienced crew to paint the apartment.

Answer:

8 hours and 8 minutes

Step-by-step explanation:

there are 24 hours on the clock so if you add 6 to the 24 it would make you be at 0:00 so then you would add 2 hours and since 28 is 8 more than 20 it would be 8 hours and 8 minutes.

Answer:

The value of c is  \(c = 0.613\)

Step-by-step explanation:

From the question we are told that

   The  mean is  \(\mu = 0\)

    The standard deviation is  \(\sigma = 1\)

      \(P( z > c) = 0.27\)

Generally From the z table the critical value corresponding to an area under the normal curve to the right with the value  0.27  is  

       \(c = 0.613\)

Answer:

A.

Step-by-step explanation:

Let's think of this as a clock.  We can see that the 2 lines start in the same place, around 3 o'clock.  Next, one of the line segments shifts down to around 6 o'clock.  Next, it shifts to about 9 o'clock.  Logically, the next step (in a clock) would be 12 o'clock, making A the correct choice.

We can also just use a regular circle, with one of the line segments moving 90 degrees each time.

Hope this helps! :)

Answer:

\(a_{5} = 22\).

Step-by-step explanation:

In this recursive sequence, the value of the first term \(a_{1} = 2\) is stated explicitly. The value of every other term of this sequence is given as an expression of the previous term.

For example, the value of the term \(a_{2}\) (\(n = 2\)) is given in terms of the value of \(a_{1}\):

\(\begin{aligned}a_{2} &= a_{(2 - 1)} + 5 \\ &= a_{1} + 5\end{aligned}\).

Likewise, the value of \(a_{3}\) (\(n = 3\)) would be:

\(\begin{aligned}a_{3} &= a_{(3 - 1)} + 5 \\ &= a_{2} + 5 \\ &= (a_{(2-1)}+5) + 5 \\ &= (a_{1} + 5) + 5 \\ &= a_{1} + 2 \times 5 \\ &= a_{1} + (3 - 1) \times 5\end{aligned}\).

In general, the value of \(a_{n}\) (for integer \(n \ge 1\)) would be:

\(\begin{aligned} a_{n} &= a_{1} + (n - 1) \times 5 \\ &= 2 + (n - 1) \times 5\end{aligned}\).

Therefore, the value of \(a_{5}\) (\(n = 5\)) would be:

\(\begin{aligned}a_{5} &= a_{1} + (5 - 1) \times 5 \\ &= 2 + (5 - 1) \times 5 \\ &= 22\end{aligned}\).

Answer: Option A.

Step-by-step explanation:

For a function f(x) = y, the domain is the set of the possible values of x.

In the image we can see that the graph has two arrows, one pointing to the left and another pointing to the right, this means that the function extends infinitely to both sides.

Then there is no value of x that generates a given problem, then the domain is the set of all real numbers.

The set written in interval notation is:

-∞ < x < ∞

Then the correct option is A.

Answer:

we have

secθ = 2

\( \frac{1}{cos θ} \)=2

Cosθ =\( \frac{1}{2 }\)

\( \frac{b}{h }=\frac{1}{2 }\)

b=1

h=2

p=\( \sqrt{2²-1} = \sqrt{3} \)

again

Cot θ=\( \frac{b}{p }\)

Cot θ=\( \frac{1}{ \sqrt{3}} \)

Cot θ=\( \frac{\sqrt{3}}{3} \)

It lies in Quadrant III cot is positive

Cot θ=\( \frac{\sqrt{3}}{3} \)

Equation of parabola: y =ax² and receiver should be placed 18 feet above vertex.

Explanation:

Considering satellite dish as parabola we can have vertex as origin and concave upward.

So, equation of parabola will be justifying structure of satellite dish i.e

y = ax² -------(1)

Two points other than (0,0) are (-12,2) and (12,2), unit being feet.

This points will satisfy equation of parabola, substituting them in equation 1, we will calculate the value of constant 'a'.

a = \(\frac{2}{12^{2} }\)

\(\frac{2}{2*6*12}\\ =\frac{1}{72}\)

Substituting value of a = 1/72 in equation 1 we get

72y = x²

As receiver need to be located at focus, so it will be places at a distance of 'p' above the vertex

4p = 72

Dividing both sides by 4, we get

p = 18 feet

So, receiver will be placed at a distance of 18 feet above vertex.

The polygon does not belong to the group as it is created by a finite number of line segments and the concept of the radius of curvature is not applicable.

In this problem we have three shapes related to circle-like and ellipse-like arcs (circle, semicircle, ellipse) and a regular polygon.

Circles are closed figures created by a arc whose radius of curvature is the same at every point and ellipses are closed figures created  by a arc whose radius of curvature varies in the following interval: a ≤ r ≤ b, where a, b are the lengths of the semiaxes.

Polygons are closed figures created by a finite number of line segments and therefore the concept of radius of curvature is not applicable.

Therefore, the polygon does not belong to the group as it is created by a finite number of line segments and the concept of the radius of curvature is not applicable.

Answer: 52,416,000 km

Step-by-step explanation:

If a comet travels 273,000 km/hr

1) Multiply 273,000 km by 24 hours to find how far the comet travels in one day

2) multiply the answer from 1 by 8 to determine how far it travels in 8 days

1) \(\frac{273,000 km}{hr}\)*\(\frac{24 hr}{1 day}\) = \(\frac{6,552,000km}{day}\) (hours cancel out)

2)\(\frac{6,552,000km}{day}\)*8 day= 52,416,000 km in 8 days

The comet approximately travelled 52,416,000km from when it began to travel to when it reached Earth. Hope this helped :)

The angles ∠DEF and ∠JKL are congruent , option(D) is correct .

Two or more angles are said to be Congruent , if they are identical to each other , OR in other words ,

the angles that have equal measure are said to be Congruent .

For Example : if ∠ABC = 60° and ∠DEF = 60°  then both the angles are congruent .

In the question ,

it is given that

the measure of ∠ABC = 120°

∠DEF = 45°

∠GHI = 30°

∠JKL = 45°

As we can see that ∠DEF and ∠JKL have equal measure of 45° , hence they are congruent .
