Answer:

A. 2 to the sixth power.

Step-by-step explanation:

As you keep going higher with powers of 2, the more and more it just keeps doubling. 2 to the power of 6 is literally 2 to the power of 5 doubled.

Answer:

-4,1

Step-by-step explanation:

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

If the coordinates of each of the vertex on the coordinate grid:

P = (2, 4)

S = (3, 4)

V = (3, 0)

The slope of PV is -4.

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

Triangle PSV:

The coordinates of each of the vertex on the coordinate grid:

P = (2, 4)

S = (3, 4)

V = (3, 0)

The slope of PV:

Choose any two coordinates from the line PV.

V = (3, 0) = (A, B)
P = (2, 4) = (C, D)

The slope of PV:

= (D - B) / (C - A)

= (4 - 0) / (2 - 3)

= 4 / -1

= -4

Thus,

If the coordinates of each of the vertex on the coordinate grid:

P = (2, 4)

S = (3, 4)

V = (3, 0)

The slope of PV is -4.

Answer:

x = 43.9

Step-by-step explanation:

sin 20° = 15/x

0.3420 = 15/x

x = 43.86

Let's solve your equation step-by-step.

10/a=15/24

Step 1: Cross-multiply.

10/a=15/24

(10)*(24)=15*a

240=15a

Step 2: Flip the equation.

15a=240

Step 3: Divide both sides by 15.

15a / 15 = 240/15

a=16

Step-by-step explanation:

1)

180-68-41= 71°

2)

180-47-16=117

5)

m<1= 180-68-77= 35°

m<2= 77°

m<3 = 180-90-41= 49°

m<4 = 180-41-62= 77°

m<5= 90-28= 62°

m<6= 180-49-103= 28°

Answer:

r

Step-by-step explanation:

sin is o/h so across from 12 would be the angle r

Answer is Option-D => ∠R

Sinθ Formula:

The sine of an angle of a right-angled triangle is the ratio of its perpendicular (that is opposite to the angle) to the hypotenuse. The sin formula is given as: sinθ = Perpendicular / Hypotenuse

Here, (Given)

Perpendicular = 12

Hypotenuse = 37

So, For sinR, we get 12/37 value as the opposite side of an angle ∠R is 12.

Answer is ∠R.

Answer: 30 kg/m³

Step-by-step explanation: density = mass / volume

Density is 240 kg / 8 m³

The main one is the Pythagorean identity,

sin²(x) + cos²(x) = 1

By dividing both sides by cos²(x), you get the tan-sec variant:

sin²(x)/cos²(x) + cos²(x)/cos²(x) = 1/cos²(x)

tan²(x) + 1 = sec²(x)

since tan(x) = sin(x)/cos(x) and sec(x) = 1/cos(x).

So the given expression reduces to

(sin²(x) + tan²(x) + cos²(x)) / sec²(x)

= (1 + tan²(x)) / sec²(x)

= sec²(x) / sec²(x)

= 1

The probability that a student has both box and a console is 1/6 and the P(B/A) = 0.378

Probability is a measure of the likelihood of an event occurring. The probability formula is defined as the possibility of an event happening being equal to the ratio of the number of favorable outcomes and the total number of outcomes. Probability of event to happen P(E) = Number of favorable outcomes/Total Number of outcomes.

Given here, the number of students with both video games is 30 thus

The probability that a student has both box and a console is 30/180=1/6

And the conditional probability P(B/A) is = 1/6/0.44

                                                                    = 0.378

Hence, The probability that a student has both box and a console is 1/6, and the P(B/A) = 0.378

Answer:

131.0 N

Step-by-step explanation:

Let the 90 N force is acting a horizontal force on the object

Horizontal force = 90 + 58sin33

Vertical force = 58cos33

∴The resultant force = √(90 + 58sin33)² + (58cos33)²
