Answer:

B

Step-by-step explanation:

To find the answer you can just input a number for x and then you should come up with a y-value.

The graph mentioned in option B is correct.

We have the the following function -

f(x) = -3 |x|

We have to select the correct graph from the given ones.

For a function f(x) = x, which is real in nature -

f(x) = |x| =  [tex]\left \{ {{-x\;\;\;for\;x < 0} \atop {x\;\;\;for\;x > 0}} \right.[/tex]

We will use this modulus property to solve the graph. We can further expand the function y = -3|x| as -

f(x) = -3|x| = [tex]\left \{ {{-3(-x)\;\;\;for\;x < 0} \atop {-3x\;\;\;for\;x > 0}} \right.[/tex]

For every negative value of x -

y = f(x) = 3x = negative value in a multiple of 3.

For every positive value of x -

y = f(x) = - 3x = negative value in a multiple of 3.

Hence, the graph mentioned in option B is correct.

Answer:

Volume:

First lets find the height of the triangle:

14 divided by 2 = 7

7 is now your base since we split it apart into two right triangles.

24^2 + 7^2 = 625

625: 25^2 = 225 perfect!

25 is now your height:

25 x 14 = 350, 350 divided by 2 (x 1/2) = 175(area of triangle)

175(area of triangle) x 20(width) = 2100, around 3500 m^3

Answer:

Growth.

Step-by-step explanation:

y = 2(1/2)x is the same as y = x. as it multiplies and divides x by 2. y = x is exponential growth.

Answer:

518,400ways

Step-by-step explanation:

nPr=n/n-r

10P3=10/(10-3)

=10/7

=10x9x8x7x6x5x4x3x2x1/7

=3,628,800/7

=518,400 ways

There is a total of 120 ways by which a teacher can ask 3 students from 10 students to complete the task.

Statistics frequently employs the binomial distribution as a discrete distribution. When compared to a binomial distribution, the normal distribution is continuous.

The chance for 'x' success of an investigation in 'n' trials is represented by the binomial distribution.

As per the given data in the question,

Total number of students in the class = 10

So, the ways the teacher can ask 3 students to complete the task will be,

= ¹⁰C₃ = 10!/[3! (10 - 3)!]

= (10 × 9 × 8 × 7!)/[3! × 7!]

= 720 / 6

= 120 ways.

Answer:

3 ft 1 in

Step-by-step explanation:

6 ft 2 inches comes to 74 inches.

50% of that is 37 inches, or 3 ft 1 in

Answer:

Distance in ft = 597.57 feet

Step-by-step explanation:

As per the

First equation of motion

84 mph = 37.5514 m/s

45 mph = 20.1168 m/s

v-u = a* t

Substituting the given values, we get -

37.5514 m/s - 20.1168 m/s = a * 6.3

a = 2.76 m/s^2

Now as per Newton's third law of motion

v^2-u^2 = 2 *a*S

Substituting the given values, we get -

37.5514^2 - 20.1168^2 = 2 * 2.76 m/s^2 * S

S = 182.142 Meters

Distance in ft = 597.57 feet

y · 90 = 33 · 100

Answer:

44.4 units

Step-by-step explanation:

Recall: 2 tangents drawn from an external point from a circle are congruent

Perimeter of the quadrilateral = AB + BC + CD + AD

AB = 3.1 + 8 = 11.1

BC = 3.1 + 8 = 11.1

CD = 11.1 (given)

AD = 8 + 3.1 = 11.1

Perimeter = 11.1 + 11.1 + 11.1 + 11.1

= 44.4 units

Answer:

circumference = 2πr

diameter = 3ft, so radius =3/2 =1.5

here diameter =3 ft

radius=diameter/2

=3/2

=1.5 ft

now use formula 2 pie r where pie =3.14
