g(x)=x^2-3 and h(x)=2x+5

find h(g(x))

Answers

Answer 1

We know that [tex]g(x) = x^2-3[/tex] and [tex]h(x) = 2x+5[/tex]. So, [tex]h(g(x))[/tex] is equal to [tex]h(x^2-3)[/tex], which is [tex]2(x^2-3)+5[/tex]. This can be simplified to [tex]2x^2-1[/tex].

Calculate the speed of a wave with a frequency of 2 Hz, amplitude of 3m, and a wavelength of 10m

Answers

Speed = wavelength * frequency
10 * 2 = 20
The speed is 20 m/s

The speed of a wave is the product of the wavelength and its frequency.

The speed of the wave is 20m/s

Given

[tex]\lambda = 10m[/tex] --- the wave length

[tex]f =2Hz[/tex] --- the frequency

[tex]A = 3m[/tex] --- the amplitude

The speed of wave (v) is calculated as follows:

[tex]v =f\lambda[/tex]

Substitute values for f and [tex]\ambda[/tex][tex]\lambda[/tex]

[tex]v = 2Hz \times 10m[/tex]

[tex]v = 20ms^{-1}[/tex]

Hence, the speed of the wave is 20m/s

Write the equation of a line in point-slope form that is parallel to the line y=2x-5 and goes through the point (-1,4)

Answers

(y-4) = 2(X+1)

Step-by-step explanation:

Hey there!

The given eqaution is; y = 2x-5.......(i)

Now; As the eqaution is in the form of y= mx+b.

Slope(m1) = 2.

As per the condition of parallel lines, slope of the 1st equation (m1) = slope of 2nd eqaution (m2).

Therefore, m1= m2= 2

Now, use one point formula for finding the eqaution of the line which passes through the point.

(y-y1) = m2(x-x1)

~ Put all values.

(y-4) = 2(X+1)

You can simply write upto here. But it you want to make it simplified form then, (look below)

~ simplify it.

y = 2x +2+4

The eqaution of the line which is parallel to y = 2x -5 and point (-1,4) is y = 2x + 6.

Hope it helps.....

Answer: y - 4 = 2(x + 1)

Step-by-step explanation:

The point slope form formula says that y - b = m(x-a) where m is the slope,b is the y coordinate of a given point , and a is the x coordinate of the same point.

Remember that parallel lines have the same slopes but different y-intercepts, meaning that m will equal to 2 because the slope for the line y=2x-5 is 2.

m will be 2, b will be 4 , and a will be -1.

y - 4 = 2(x - (-1) which reduces to

y - 4 = 2(x + 1)

Jane can paint the office by herself in 7 hours.

with an associate, she can paint the office in 3 hours.

The combined work rate is 3 hours per office

Required

the work rate for the associate

Step two:

let the expression for the wok rate be

1/A+1/B= 1/T

1/7+1/B=1/3

1/B=1/3-1/7

1/B= 8-4/21

1/B= 4/21

B= 21/4

B=5.3 hours

the work rate for the associate is 5.3 hours

Which shows the result of a correct substitution for the system y=2x+3 and 3x+2y=9?

Answers

Answer:

The result of the correct substitution gives:

x = 3/7 and y = 27/7

Step-by-step explanation:

From the given information:

y = 2x + 3 ---- (1)

3x + 2y = 9 ---- (2)

By using substitutional method

Substitute the value of y = 2x +3 into equation (2)

So,

3x + 2(2x + 3) = 9

3x + 4x + 6 = 9

7x = 9 - 6

7x = 3

x = 3/7

From equation (1), let replace the value of x to be 3/7

So,

y = 2x + 3

y = 2(3/7) + 3

y = 6/7 + 3

y = 27/7

The position of a particle moving along the x-axis is given by a twice-differentiable function x(t). If x(2) < 0, x'(2) < 0, and x''(2) <0, which of the following statements must be true about the particle at time t=2?

a. The particle is moving toward the origin at a decreasing speed.
b. The particle is moving toward the origin at an increasing speed.
c. The particle is moving away from the origin at a decreasing speed.
d. The particle is moving away from the origin at an increasing speed.
e. The particle is moving away from the origin at a constant speed.

Answers

Answer:

c. The particle is moving away from the origin at a decreasing speed.

Step-by-step explanation:

Since x(2) which represents the particles position is less than zero, that is, x(2) < 0, it shows that the particle is at the left of the origin at t = 2.

Also, x'(2) which represents the particle's speed at t = 2 is less than zero, that is, x(2) < 0, the particles speed is negative at t = 2.

Finally, since x"(2) which represents the particle's acceleration at t = 2 is less than zero, that is, x"(2) < 0, the particle's acceleration is negative at t = 2 and thus decreasing.

So, combining these three conditions together shows that the particle is moving away from the origin at a decreasing speed at time, t = 2.

Since [tex]x(2)[/tex], which represents the subatomic particle location, is below zero, that is, [tex]x(2) <0[/tex], it indicates that the particles are to the left of the origin at [tex]t = 2.[/tex]

Therefore, [tex]x'(2)[/tex], which represents the particle's speed at [tex]t = 2[/tex], is less than zero, implying that[tex]x(2) <0[/tex], the subatomic particle speed at [tex]t=2[/tex], is negative.Furthermore, because [tex]x"(2)[/tex], which represents that particle's acceleration at [tex]t = 2[/tex], is less than zero, [tex]x"(2)< 0[/tex], the particle's acceleration at [tex]t = 2[/tex] is negative and consequently declining.Considering these three requirements reveals that at the moment [tex]t = 2[/tex], the particle is moving away from the nucleus at a decreasing speed.

Therefore, the answer is "Option C".
