Answer:

sin -115 = -0.91, cos -115 = -0.42

Step-by-step explanation:

The sine and cosine of -115 degrees sin -115 = 0.91 and   cos -115 degrees = -0.42.

Since sine and cosine are both periodic functions, their values repeat every 360 degrees. Therefore, the sine and cosine of -115 degrees are the same as the sine and cosine of 115 degrees, respectively.

So, sin -115 = 0.91 and cos -115 degrees = -0.42.

Here is a table of the sine and cosine of angles from 0 to 360 degrees:

Angle | Sine | Cosine

------- | -------- | --------

0 degrees | 0 | 1

30 degrees | 0.5 | 0.866

45 degrees | 0.707 | 0.707

60 degrees | 0.866 | 0.5

90 degrees | 1 | 0

120 degrees | 0.866 | -0.5

135 degrees | 0.707 | -0.707

150 degrees | 0.5 | -0.866

180 degrees | 0 | -1

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

Explanation:

See the diagram below. The two given angles B = 105 and C = 20 are used to help find angle A

A+B+C = 180

A+105+20 = 180

A+125 = 180

A = 180-125

A = 55

Then we use the law of sines to find the side length c

sin(A)/a = sin(C)/c

sin(55)/15 = sin(20)/c

c*sin(55) = 15*sin(20) ... cross multiply

c = 15*sin(20)/sin(55)  .... divided both sides by sin(55)

c = 6.26294249724791 .... value is approximate

c = 6.3 ....... rounding to one decimal place

Answer:

The answer is "728 routes"

Step-by-step explanation:

The number of ways to proceed from (0, 0) to (5, 7) is as follows:

[tex]\Rightarrow \frac{(7+5)!} {(7! \times 5!)} \\\\ \Rightarrow \frac{12!}{(7! \times 5! )}\\\\\Rightarrow \frac{12 \times 11 \times 10 \times 9 \times 8 \times 7!}{7! \times 5!}\\\\\Rightarrow \frac{12 \times 11 \times 10 \times 9 \times 8}{5!}\\\\\Rightarrow \frac{12 \times 11 \times 10 \times 9 \times 8}{5\times 4 \times 3 \times 2 \times 1}\\\\\Rightarrow \frac{ 11 \times 9 \times 8}{1}\\\\\Rightarrow 11 \times 9 \times 8\\\\\Rightarrow 11 \times 72\\\\\Rightarrow 792[/tex]

We would like to delete the ways of (0, 0) to (2, 3)  That's the resolution:

[tex]\Rightarrow \frac{(3+2)!}{(3!\times2!)} \\\\ \Rightarrow \frac{5!}{(3!\times2!)} \\\\\Rightarrow \frac{5\times 4\times 3! }{(3!\times2 \times 1)} \\\\\Rightarrow \frac{5\times 4}{(2 \times 1)} \\\\\Rightarrow \frac{5\times 2}{1} \\\\\Rightarrow 10 \ ways[/tex]

[tex]So, \\\\ \Rightarrow 792 -10 \\\\ \Rightarrow 782 \ routes[/tex]

Answer:

The answer should be 210 unit cubes.

Step-by-step explanation:

The volume of a rectangular prism is given by the following expression:

[tex]volume = length*width*height[/tex]

In words, it is the product of its edge lengths. If the prism was packed with 210 unit cubes, then this must be equal to its volume, so by multiplying the edge lengths the result should be equal to 210 unit cubes.

Answer:

8(x-9)(x-3)

Step-by-step explanation:

First expand the expression:

4(2x-6) x 3(x-3) = (8x-24) x (x-9)

Now use distribution method top multiply the 2 brackets:

8x^2 - 72x - 24x + 216

simplify:

8x^2 - 96x +216.

You can factorize this:

8(x-9)(x-3)

Answer:

Step-by-step explanation:

The only valid expression from the given list is the one that uses the arctangent ([tex]tan^{-1}(0.75)[/tex] ) function.

Recall that the tangent of an acute angle in a right angle triangle is defined as:

[tex]tan(B)=\frac{opposite}{adjacent}[/tex]

therefore in our case we have:

[tex]tan(B)=\frac{opposite}{adjacent} \\tan(B) = \frac{12}{16} \\tan(B)=0.75\\B=arctan(0.75)[/tex]

Answer:

61%

Step-by-step explanation:

Area of square:

=a²

=12²

=144

Area of two quarter circles:

=2(¼×π×r²)

=2(¼×π×6²)

=2×28.72

=56.55

Finding the percentage:

=(56. 55÷144)×100

=0.3937×100

=39.27

subtract 100% by 39.27% to find the percentage of how much is shaded

=100-39.27

=60.73

=61 (rounded off to the nearest whole percent)

Answer:

x=11  solution is not extraneous

Step-by-step explanation:

sqrt( x-5) +7 = 11

Subtract 7 from each side

sqrt( x-5) +7-7 = 11-7

sqrt(x-5) = 4

Square each side

(sqrt(x-5))^2 = 4^2

x-5 = 16

Add 5 to each side

x-5+5 = 16+5

x = 21

Check

sqrt( 21-5) +7 = 11

sqrt(16) +7 =11

4+7 =11

11=11

Valid solution

Answer:

B)  x = 21, solution is not extraneous

Step-by-step explanation:

√(x - 5) + 7 = 11

(√(x - 5) + 7) - 7 = 11 - 7

√(x - 5) = 4

(√(x - 5))² = (4)²

x - 5 = 16

(x - 5) + 5 = 16 + 5

x = 21

The solution is not extraneous.  An extraneous solution is a solution that is not included in the domain.  For this equation the domain would be [-5, ∞).  The solution found is included in the domain

Step-by-step explanation:

Answer:

Step-by-step explanation:

Answer:

r = 5

Step-by-step explanation:

The n th term of a geometric sequence is

[tex]a_{n}[/tex] = a₁ [tex]r^{n-1}[/tex]

where a₁ is the first term and r is the common ratio

Here a₁ = 1 and a₅ = 625, thus

1 × [tex]r^{4}[/tex] = 625 , so

r = [tex]\sqrt[4]{625}[/tex] = 5

The common ratio of the geometric sequence is 5 if the geometric sequence for which a1=1 and a5=625 the answer is 5.

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

We have a geometric sequence for which:

The first term a1 = 1

and fifth term:

a5 = 625

As we know, the geometric sequence follows a certain arithmetic rule of multiplication.

The nth term of the geometric sequence is:

a(n) = arⁿ⁻¹

a1 = a = 1

a5 = ar⁵⁻¹ = 625

Take the ratios:

a/ar⁵⁻¹ = 1/625

r is the common ratio.

1/r⁴ = 1/625

r⁴ = 625

r = 5

The common ratio is 5.

Thus, the common ratio of the geometric sequence is 5 if the geometric sequence for which a1=1 and a5=625 the answer is 5.

Answer:

Step-by-step explanation:

The question is not properly structured. Here is the complete question.

For cones with radius 6 units, the equation V=12\pi h relates the height h of the cone, in units, and the volume V of the cone, in cubic units. Sketch a graph of this equation on the axes.

The formula for calculating the volume of a cone is expressed as shown;

[tex]V = \frac{1}{3} \pi r^{2} h[/tex] where r is the radius and h is the height.

Given radius r = 6units, on substituting;

[tex]V = \frac{1}{3}*\pi *6^{2}*h\\ V = \frac{36\pi h}{3}\\V = 12\pi h... (1)[/tex]

It can be seen from the derived volume of the cone that it is linear in nature. The volume of the cone has a linear relationship with its height. As the volume increases, the height also increases and vice versa.

where k is the constant of proportionality. comparing to equation 1, k = 12π.

Find the graph attached

Answer:

The equation is x² + y² = 144.

Step-by-step explanation:

This works the same way as before.

You know that at the origin, it equals (0, 0). So, we have no need to insert values for h and k. Therefore, it will just be x² + y² = r².

R is your radius, and this is given as 12 units. So, r = 12. Therefore, r² = 144.

Your final equation is x² + y² = 144.

Answer:

Step-by-step explanation:

The rule is if 2 chords intersect inside a circle, then the measure of the angle formed is one half the um of the measure of the arcs intercepted by the angle and its vertical angle. In other words, angle TSU = 1/2(arc TU + arc MV):

angle TSU = 1/2(90 + 80) and

angle TSU = 1/2(170) and

angle TSU = 85

Answer: (0,-9)

Step-by-step explanation:

(0,-9) is the y-intercept because it is the point at which the function crosses the y-axis.
