What is 17.445 - 6.76 rounded to the nearest tenth

Answer:

[tex]\sec \theta = \frac{\sqrt{22}}{4}[/tex]

Step-by-step explanation:

Given

[tex]\tan^2 \theta = \frac{3}{8}[/tex]

Required

[tex]\sec\ \theta[/tex]

We have:

[tex]\sec^2\theta = 1 + \tan^2 \theta[/tex]

This gives:

[tex]\sec^2\theta = 1 + \frac{3}{8}[/tex]

Take lcm and solve

[tex]\sec^2\theta = \frac{9+3}{8}[/tex]

[tex]\sec^2\theta = \frac{11}{8}[/tex]

Take square roots

[tex]\sec \theta = \frac{\sqrt{11}}{\sqrt 8}[/tex]

[tex]\sec \theta = \frac{\sqrt{11}}{2\sqrt 2}[/tex]

Rationalize

[tex]\sec \theta = \frac{\sqrt{11}}{2\sqrt 2} * \frac{\sqrt 2}{\sqrt 2}[/tex]

[tex]\sec \theta = \frac{\sqrt{22}}{4}[/tex]

Answer:

  C. A horizontal stretch by a factor of 5/4

Step-by-step explanation:

Replacing x in f(x) by kx introduces a horizontal compression by a factor of k, or a stretch by a factor of 1/k. Here, we have k=4/5, so the curve is stretched horizontally by a factor of 5/4.

Answer:

0.26 or C

Step-by-step explanation:

Basically you would do the sophomores that attended the jazz band concert (35) and divide that by the total number of students. (137) - - 35 ➗ 137 = .2554744526 round that to .26 or 0.26

The probability that a randomly chosen person from this group exists a sophomore and attended the jazz band concert is 0.31.

Probability exists about calculating or estimating how possible or 'probable' something exists to occur.

Let A be the event that a person exists a sophomore.

B be the event that a person attended volleyball game.

A∩B denote the event that a person exists a sophomore and attend volleyball game.

P be the probability of an event.

We have to estimate the value of P(A∩B),

Given: A∩B = 42

P(A∩B) = 42/137 = 0.3065 approximately equal to 0.31

P(A∩B) = 0.31.

The probability that a randomly chosen person from this group exists a sophomore and attended the jazz band concert is 0.31.

Therefore, the correct answer is option D. 0.31.

Step-by-step explanation:

17 cubic units.

The volume (V) of a parallelepiped with one vertex at the origin is given by the absolute value of the scalar vector product of the vectors at the adjacent vertices.

V = |(a x b) · c|

In this case,

a = (1,4,0) = i + 4k + 0j

b = (-2,-5,2) = -2i -5j + 2k

c = (-2,2,1) = -2i + 2j + k

First, let's calculate the cross product of vectors a and b. i.e a x b as follows:

(i) Arrange the vectors in a matrix form

a x b = | i        j         k |

          | 1       4        0 |

          | -2    -5        2 |

(ii) Calculate the determinant of the matrix

a x b = i(8 - 0) -j(2-0) + k(-5+8)

a x b = i(8) -j(2) + k(3)

a x b = 8i - 2j + 3k

Secondly, calculate the scalar product of the cross product found above and the vector c as follows;

(a x b) . c = (8i - 2j + 3k) · (-2i + 2j + k)

Multiply like terms

(a x b) . c = (8 * -2)(i.i) + (-2 * 2)(j.j) + (3 * 1)(k.k)             [i.i = j.j = k.k = 1]

(a x b) . c = (-16) + (-4) + (3)

(a x b) . c = -16 - 4 + 3

(a x b) . c = -17

Thirdly, find the absolute value of the result found above. i.e

|(a x b) . c| = |-17|

|(a x b) . c| = 17

Therefore, the volume of the parallelepiped is 17 cubic units.

====================================================

Explanation:

Plug in the lower bound of the domain, which is x = -3

f(x) = 3x+2

f(-3) = 3(-3)+2

f(-3) = -9+2

f(-3) = -7

If x = -3, then the output is y = -7. Since f(x) is an increasing function (due to the positive slope), we know that y = -7 is the lower bound of the range.

If you plugged in x = 5, you should find that f(5) = 17 making this the upper bound of the range.

The range of f(x) is -7 < y < 17

Recall that the domain and range swap places when going from the original function f(x) to the inverse [tex]f^{-1}(x)[/tex]

This swap happens because how x and y change places when determining the inverse itself. In other words, you go from y = 3x+2 to x = 3y+2. Solving for y gets us y = (x-2)/3 which is the inverse.

-----------------------

In short, we found the range of f(x) is -7 < y < 17.

That means the domain of the inverse is -7 < x < 17 since the domain and range swap roles when going from original to inverse.

The domain of the resulting function exists on all real values that is the domain is -∞ < f-1(x) < ∞

The domain of a function are the independent values of the function for Which it exists.

Given the function f(x) = 3x + 2

Find its inverse

y = 3x + 2

Replace x with y

x = 3y + 2

Make y the subject of the formula:

3y = x - 2
y = (x-2)/3

The domain of the resulting function exists on all real values that is the domain is -∞ < f-1(x) < ∞

We keep brackets

(4n^2 + 3n - 5 ) -  (2n^2 + 3n + 6)

We change signs and we group

4n^2 - 2n^2 + 3n - 3n - 5-6

We simplify

2m^2 - 11

Answer: = 2.n^2  - 11

The value of (4n^2 + 3n - 5) - (2n^2 + 3n+ 6) is 2n^2 - 11

The polynomial expression is given as;

(4n^2 + 3n - 5) - (2n^2 + 3n+ 6)

Open the bracket

4n^2 + 3n - 5 - 2n^2 - 3n- 6

Evaluate the like terms

2n^2 - 11

Hence, the value of (4n^2 + 3n - 5) - (2n^2 + 3n+ 6) is 2n^2 - 11
