A bucket holds 10 white golf balls, 3 pink golf balls, and 5 yellow golf balls. Jason selects 1 golf ball from the bucket at random.

What is the probability that the golf ball he selects is white or pink?

5/54

5/13

13/18

13/5

Answers

Answer:

I would have to say 5/13 and if I'm wrong I'm sorry just trying to help you out

Add them together first. You get in total 18. So that’s your base number. Then add the white balls that is 10 and the pink balls that is 3. The reason why I don’t add the 5 yellow balls is because they are not mentioned in the third sentence. When you added those you will end up with 13/18.

What is the measure of the smallest angle in the diagram?

15°
29°
32°
45°

Answers

Answer:

b. 29°

Step-by-step explanation:

In the given diagram, the smallest angle in the diagram is ∠FLG = 29°.

What is an angle?

When to lines are meeting at a point, then the geometrical figure is formed called an angle.

Given, four lines extend from point L.

They are lines LF, LG, LH, and LI.

∠FLI = 106°, ∠FLG = (2x - 1)°, ∠GLH = (x + 17)°, ∠HLI = (4x - 15)°

Here, ∠FLI = ∠FLG + ∠GLH + ∠HLI

106°  = (2x - 1)° + (x + 17)° + (4x - 15)°

⇒ (2x - 1)° + (x + 17)° + (4x - 15)° = 106°

⇒ (7x + 1)° = 106°

⇒ 7x = 105

⇒ x = 15

Now, ∠FLG = (2x - 1)° = (2 × 15 - 1)° = 29°

GLH = (x + 17)° = (15 + 17)° = 32°

∠HLI = (4x - 15)° = (4 × 15 - 15)° = 45°

Therefore, the smallest angle in the diagram is ∠FLG = 29°.

Which is the graph of f(x) = RootIndex 3 StartRoot x EndRoot – 4?

Answers

Answer:

Graph shown below

Step-by-step explanation:

Cubic Root Graph

The graph of the function

[tex]f(x)=\sqrt[3]{x}-4[/tex]

Is shown in the attached image. Some points are calculated below:

We'll take x={-8,-1,0,1,8}:

[tex]f(-8)=\sqrt[3]{-8}-4=-2-4=-6[/tex]

Point (-8,-6)

[tex]f(-1)=\sqrt[3]{-1}-1=-1-4=-5[/tex]

Point (-1,-5)

[tex]f(0)=\sqrt[3]{0}-4=0-4=-4[/tex]

Point (0,-4)

[tex]f(1)=\sqrt[3]{1}-1=1-4=-3[/tex]

Point (1,-3)

[tex]f(8)=\sqrt[3]{8}-1=2-4=-2[/tex]

Point (8,-2)

The graph of [tex]\rm f(x) = \sqrt[3]{x} - 4[/tex] is attached below and this can be sketched by substituting the values of x in the function f(x) and then plotting the points on the graph.

Given :

[tex]\rm f(x) = \sqrt[3]{x} - 4[/tex]

The following steps can be used in order to determine the graph of the given function f(x):

Step 1 - Determine the value of f(x) at the values of x = {-8,-4,0,4,8}.

Step 2 - At (x = -8) the value of f(x) is given by:

[tex]\rm f(x) = \sqrt[3]{-8} - 4[/tex]

[tex]\rm f(x) = -2 - 4 = -6[/tex]

Step 3 - At (x = -4) the value of f(x) is given by:

[tex]\rm f(x) = \sqrt[3]{-4} - 4[/tex]

f(x) = -5.6

Step 4 - At (x = 0) the value of f(x) is given by:

[tex]\rm f(x) = \sqrt[3]{0} - 4[/tex]

f(x) = -4

Step 5 - At (x = 4) the value of f(x) is given by:

[tex]\rm f(x) = \sqrt[3]{4} - 4[/tex]

f(x) = -2.4

Step 6 - At (x = 8) the value of f(x) is given by:

[tex]\rm f(x) = \sqrt[3]{8} - 4[/tex]

f(x) = -2

Step 7 - Now, plot the points obtained in the above steps on the graph in order to draw the graph of the given function [tex]\rm f(x) = \sqrt[3]{x} - 4[/tex]

The of the function [tex]\rm f(x) = \sqrt[3]{x} - 4[/tex] is attached below.

Find (f•g)(x).

Answers

Step-by-step explanation:

(f o g)(x)

= f(3x² - 5)

= (3x² - 5) + 2

= 3x² - 3.

(f.g)(x) = 3x^2 - 3

f(x) = x + 2
g(x) = 3x^2 - 5

What is equation?

equation is the relationship between variable and represented as     is example of polynomial equation.

f(x) = x + 2
g(x) = 3x^2 - 5

now putting the x = g(x)
in f(x) = x + 2
Thus,
f(g(x)) = 3x^2 - 5 + 2
f(g(x)) = 3x^2 - 3

Thus, (f.g)(x) = 3x^2 - 3

A student thinks that the regular pentagon in the diagram
has 10 lines of symmetry. Explain the student's error.

Answers

Answer:

A

Step-by-step explanation:

The student must have thought that every single arrowhead is a line of symmetry, so since there are 10 arrowheads, there must be 10 lines of symmetry. This is incorrect because if you look closely at the diagram, each line has 2 arrowheads, so the student is overcounting by a factor of 2. They should have just counted the number of lines, not arrowheads. Therefore, there must be 10/2 = 5 lines of symmetry, not 10. Hope this helps!

Building A is 400 feet tall and Building B is 300 feet tall. Johnny is standing in between the two building. The angle of elevation from the point on the ground where Johnny is standing is 70 degrees to the top of Building A and 52 degrees to the top of Building B. How far apart are the two buildings

Answers

Answer:

389 feets apart

Step-by-step explanation:

Given that:

Building A

Height = 400feets

Angle of elevation = 70°

Building B:

Height = 300 feets

Angle of elevation = 52°

Distance from the foot of building A to where Jonny is standing = x (see attached picture)

Using trigonometry :

Tanθ = opposite / Adjacent

Tan 70 = 400/ x

2.7474774x = 400

x = 145.58809 feets

Distance from the foot of building B to where Jonny is standing = y (see attached picture)

Using trigonometry :

Tanθ = opposite / Adjacent

Tan 52 = 300/ y

1.2799416y = 300

y = 145.59

y = 234.38568 feets

x + y = distance between the two buildings

(145.58809 + 234.38568) feets

= 379.97377

= 380 feets apart
