Answer:

Period: [tex]2\pi[/tex]

Step-by-step explanation:

The function [tex]f(x)=asin(bx-c)+d[/tex] has a period of [tex]\frac{2\pi}{|b|}[/tex], therefore [tex]f(x)=sinx[/tex] has a period of [tex]2\pi[/tex], where the wave cycle of the function repeats every [tex]2\pi[/tex] units. See the attached graph for a visual.

Answer:

[tex]30\ cm^2[/tex]

Step-by-step explanation:

The formula to find the area of a triangle is the following,

[tex]A=\frac{(b)(h)}{2}[/tex]

Where (A) represents the area, (b) represents the base, and (h) represents the height. Substitute in the given values and solve for the area.

[tex]A=\frac{(b)(h)}{2}\\\\A=\frac{(5)(12)}{2}\\\\A=\frac{60}{2}\\\\A=30[/tex]

We know that, Area of a Triangle is given by :

[tex]\bigstar \ \ \boxed{\sf{A = \dfrac{1}{2} \times Base \times Height}}[/tex]

Given:

- Height = 5 cm

- Base = 12 cm

[tex]\implies \sf{Area = \dfrac{1}{2} \times 12 \times 5}[/tex]

[tex]\implies \sf{Area = 6 \times 5}[/tex]

[tex]\implies \sf{Area \ of \ the \ Triangle = 30 \ cm^2}[/tex]

Answer:

1) Slope = 2; y-intercept = 3

2) Slope = -3.7; y-intercept = 18

Answer:

Step-by-step explanation:

[tex](\frac{f}{g} )(x) = \frac{2x^{2} +4x-16}{4x^{2} -16}[/tex]

2x²+4x -16 =  2(x²+2x-8); factor 2

                  = 2(x+4)(x-2) ;factor the quadratic equation

4x²-16  = 4(x²-4) ; factor 4

            =4(x²- 2²) ; rewrite 4 as 2²

           = 4(x-2)(x+2); now use the difference of two squares a²-b²=(a-b)(a+b)

so now we have:

[tex](\frac{f}{g}) (x) = \frac{2(x+4)(x-2)}{4(x-2)(x+2)}[/tex] ; simplify (x-2) from numerator and denominator

                                  and 2/4 as 1/2

[tex](\frac{f}{g}) (x) = \frac{(x+4)}{2(x+2)}[/tex]

Answer:

Step-by-step explanation:

The z score shows by how many standard deviations the raw score is above or below the mean. The z score is given by:

[tex]z=\frac{x-\mu}{\sigma} \\\\where\ x=raw\ score,\mu=mean, \ \sigma=standard\ deviation[/tex]

Given that mean (μ) = 130 texts, standard deviation (σ) = 20 texts

1) For x < 90:

[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{90-130}{20} =-2[/tex]

From the normal distribution table, P(x < 90) = P(z < -2) = 0.0228 = 2.28%

Option 1 is correct

2) For x > 130:

[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{130-130}{20} =0[/tex]

From the normal distribution table, P(x > 130) = P(z > 0) = 1 - P(z < 0) = 1 - 0.5 = 50%

Option 2 is correct

3) For x > 190:

[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{190-130}{20} =3[/tex]

From the normal distribution table, P(x > 3) = P(z > 3) = 1 - P(z < 3) = 1 - 0.9987 = 0.0013 = 0.13%

Option 3 is incorrect

4)  For x < 130:

[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{130-130}{20} =0[/tex]

For x > 100:

[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{100-130}{20} =-1.5[/tex]

From the normal table, P(100 < x < 130) = P(-1.5 < z < 0) = P(z < 0) - P(z < 1.5) = 0.5 - 0.0668 = 0.9332 = 93.32%

Option 4 is incorrect

5)  For x = 130:

[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{130-130}{20} =0[/tex]

Option 5 is incorrect

6)  For x = 130:

[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{160-130}{20} =1.5[/tex]

Since 1.5 is between 1 and 2, option 6 is correct

Answer:

I think it's AA because the sum of a triangle is 180 and if you subtract the right angle and the other angle from 180 it gives you the same angle in the other triangle.

Step-by-step explanation:

180-(90+70)=20 The other angle in the first triangle

180-(90+20)=70 The other angle in the second triangle

These angles show that they're similar

Answer:

36 inches

Step-by-step explanation:

Given data

Area of triangle =2 1/4 square inches

Area =9/4 square inches

Height of triangle =1/8 inches

We know that the expression for the area of triangle is

Area = 1/2Base *Height

9/4=1/2*Base *1/8

9/4=Base/16

Cross multiply

16*9=Base*4

144=Base*4

Base =144/4

Base=36 inches

Answer:

The largest interior angle of ΔCDF is ∠F

Step-by-step explanation:

The bearings of the vertices of the triangle are given as follows;

The bearing of C from D = 056°

The bearing of F from D = 115°

The bearing of F from C = 184°

By angle addition property, we have;

The bearing of F from D = The bearing of C from D + ∠D

∴ ∠D = The bearing of F from D - The bearing of C from D

By plugging in the values, we have;

∠D = 115° - 056° = 59°

∠D in triangle ΔCDF = 59°

∠D = 59°

By alternate interior angles, we have;

The bearing of C from D = 056° = ∠BCD

Also, we have;

The bearing of F from C = ∠BCF + ∠ACB

∠ACB = 180°

∴ ∠BCF = The bearing of F from C - ∠ACB

∠BCF = 184 - 180° = 4°

∠C in ΔCDF = ∠BCD - ∠BCF

∴ ∠C = 056° - 4° = 52°

∠C = 52°

From angle sum property of ΔCDF, we have; ∠F = 180° - ∠C - ∠D

Therefore; ∠F = 180° - 52° - 59° = 69°

We have; ∠C = 52°, ∠D = 59°, ∠F = 69°, therefore;

∠F in triangle ΔCDF, has the largest interior angle.
