In which set of points is y a function of x?

Answer:

[tex]y=-5x+0[/tex]

Step-by-step explanation:

We know that slope intercept form is:

[tex]y=mx+b[/tex]

And our slope is -5, and the variable we use for slope is m:

[tex]m=-5[/tex]

Our new equation becomes:

[tex]y=-5x+???[/tex]

And our y-intercept is 0, and the letter we use to express our y-intercept is b:

[tex]b=0[/tex]

Our new equation is:

[tex]y=-5x+0[/tex]

Hence, the correct answer is [tex]y=-5x+0[/tex]

The expected number of defective bolts are obtained as 175. The correct option is (C).

Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.

The probability of any event always lie in the close interval of 0 and 1 [0,1].

The zero value of probability indicates that the event will not happen while its value equal to one indicate that it will happen.

The total number of bolts tested are 24.

And, the number of defective bolts are 5.

Then, the probability of defective bolts is given as,

P(defective bolts) = 5/24

Now, the expected number of bolts can be found as,

Expected number = P(defective bolts) × Total number of bolts tested

⇒ 5/24 × 850 = 175

Hence, the expected number of bolts that will be defective is given as 175.

Answer:

48 , 132

Step-by-step explanation:

Let smaller angle = x

Larger angle = 3x - 12

x & (3x - 12) are supplementary

So, x + 3x - 12 = 180°

          4x - 12 = 180

                  4x = 180 +12

                   4x = 192

                     x = 192/4

x = 48°

Larger angle = 3*48 - 12 = 144 - 12 = 132

Answer: The measure of the smaller angle is 48,and the larger angle is 132.

The volume of the hexagonal prism is the amount of space in it.

From the complete question, we have:

Length (l) = 8

Height (h) = 5

The surface area of the hexagonal prism is:

[tex]A=6lh+3l^2\sqrt 3[/tex]

So, we have:

[tex]A=6*8*5+3*5^2\sqrt 3[/tex]

Evaluate

[tex]A = 369.9[/tex]

Hence, the surface area is 369.9 square feet

The volume of the hexagonal prism is:

[tex]V = \frac{3\sqrt 3}{2} * l^2h[/tex]

So, we have:

[tex]V = \frac{3\sqrt 3}{2} * 8^2 * 5[/tex]

Evaluate

[tex]V = 831.4[/tex]

Hence, the volume is 831.4 cubic feet

The measure of angle MBT as shown in the diagram is 28 degrees.

An angle is formed from the intersection of two or more lines. Types of angles are obtuse, acute and right angled.

From the diagram:

∠MBN = ∠MBT

17x - 6 = 5x + 18

x = 2

∠MBT = 5(2) + 18 = 28 degrees

The measure of angle MBT as shown in the diagram is 28 degrees.

Answer:

B. The function f(x) = tan(x) is an odd function because f(-x) = -f(x)

Step-by-step explanation:

The function f(x) = tan(x) is odd as  [tex]f(-x) = -f(x)[/tex]  so we can conclude the statement B. The function f(x) = tan(x) is an odd function because [tex]f(-x) = -f(x)[/tex] is the true option.

The function is a relation used to determine a value f(x) for a given x using an expression in x.

An even function is when f(x) = f(-x). It is symmetric along the y-axis.

An odd function is when f(-x) = -f(x). It is symmetric along the x-axis.

We are dealing with the function f(x) = tan(x).

We calculate f(-x) = tan(-x) = -tan(x) = -f(x).

∴ The function f(x) = tan(x) is an odd function, and odd functions are symmetric about the origin.

∴ The function f(x) = tan(x) is odd as  [tex]f(-x) = -f(x)[/tex]  so we can conclude the statement B. The function f(x) = tan(x) is an odd function because [tex]f(-x) = -f(x)[/tex] is the true option.
