Someone please help, I have a midterm and I have no idea what I’m doing ‍♀️

Answer:

3

Step-by-step explanation:

3

The answer is 3 because it is the opposite of negative 3

The airplane that descends at a rate of 2,700 feet per minute, after 3 1/2 minutes it will be at 9450 ft

The formula and procedure we will use to solve this problem is:

v= x/t

Where:

Information about the problem:

Converting the mixed fraction to a fraction, we get:

3 1/2 =

[(3*2) + 1]/2 =

(6+1) / 2 =

7/2

3 1/2 min is equivalent to 7/2

Applying the velocity and isolating the distance we have:

x= v*t

x = 2700 ft/min * 7/2 min

x = 9450 ft

It is a physical quantity that indicates the displacement of a mobile per unit of time, it is expressed in units of distance per time, for example (miles/h, km/h).

It would drop the grade down to about a B- or C+

Step-by-step explanation:

Answer: [tex]\sqrt{170}[/tex]

Step-by-step explanation:

Distance formula: a^2+b^2=c^2 where c is the distance between two points

(-6-5)^2 + (4-(-3))^2=c^2

(-(6+5))^2 + (4+3)^2=c^2

(-11)^2 + 7^2=c^2

121 + 49=c^2

c^2=170

c=[tex]\sqrt{170}[/tex]   ==> distance between A and B

Answer:

4c^2 - 3a^2 -7ac +6bc -ab

Step-by-step explanation:

solve first 3a( a + b + c) - 2b ( a+ b +c)

which is = 3a^2 + 3ab + 3ac - 2ab - 2b^2 -2bc

there for 4c(-a + b +c) -( 3a^2 + 3ab + 3ac - 2ab - 2b^2 - 2bc)

= -4ac-3ac +4bc+2bc -3ab+2ab + 4c^2 -3a^2

=4c^2 - 3a^2 -7ac +6bc -ab

Answer:

15

Step-by-step explanation:

Here, given the diagonals of the Rhombus, we want to get the length of one side of the Rhombus

We proceed to use the formula below;

d1 = √(4a^2-d2^2

Where d1 represents the length of one diagonal

a is the side of the Rhombus

d2 is the length of the second diagonal

Thus, mathematically;

d2^2 = 4a^2 - d1^2

4a^2 = d2^2 + d1^2

4a^2 = 18^2 + 24^2

4a^2 = 900

a^2 = 900/4

a^2 = 225

a = √225

a = 15

Answer:

y = 6x + 3

Step-by-step explanation:

Equation of the line

------------------------------------------------------

The equation of the line in slope-intercept form is:

y = mx + b

Being m the slope and b the y-intercept.

Where m is the slope and (h,k) is a point through which the line passes.

We are given the y-intercept as b=3 m=6.

Thus, the equation of the line is:

y = 6x + 3

Answer:

11.7 ft (11.661903789691 )

Step-by-step explanation:

Draw a right triangle. Legs are 10 ft and 6 ft, we're trying to find the hypotenuse.

We can use the Pythagorean theorem.

a^2 + b^2 = c^2

c = √a2 + √b2

  =  √(10)2 + √(6)2

  = √100 + √36

  = √136

  = 11.661903789691

Answer:

(3,4)

Step-by-step explanation:

Find equations of both lines

Line 1: y = 1/3x + 3

Line 2: y = 2x - 2

Set then equal to each other, then solve for x:

1/3x + 3 = 2x - 2

1/3x + 5 = 2x

x + 15 = 6x

15 = 5x

x = 3

Then sub x into one of the equations (doesn't matter which one) and solve for y

y = 2x - 2

y = 2(3) - 2

y = 6 - 2

y = 4

Solution is (3,4)

Answer:

B: 30°, 78°, 72

Step-by-step explanation:

Given a [tex]\triangle ABC[/tex].

Let [tex]\angle A = x^\circ[/tex]

As per question statement, [tex]\angle B[/tex] is 18° more than twice of [tex]\angle A[/tex].

i.e

[tex]\angle B =(2x+18)^\circ[/tex]

[tex]\angle C[/tex] is 42° more than that of [tex]\angle A[/tex]

[tex]\angle C = (x+42)^\circ[/tex]

To find:

The angle measures of the triangle = ?

Solution:

We can use the angle sum property of a triangle here to find the three angles of the triangle.

As per angle sum property, the sum of all the three internal angles is equal to [tex]180^\circ[/tex].

[tex]\angle A + \angle B + \angle C= 180^\circ\\\Rightarrow x+2x+18+x+42=180^\circ\\\Rightarrow 4x+60=180\\\Rightarrow 4x=120\\\Rightarrow x= 30^\circ[/tex]

i.e. [tex]\angle A = 30^\circ[/tex]

[tex]\angle B = 2\times 30 + 18 = 78^\circ[/tex]

[tex]\angle C = 30+42 = 72^\circ[/tex]

Therefore, the correct answer is:

B: 30°, 78°, 72

Answer:

D,

Step-by-step explanation:

D would be the only one that doesn't represent a function because the y-value never changes while the x-value does.

The fewest number of points that must be plotted to have examples of all four sets of numbers is including at least one positive and one negative​ integer is 2 points

The  Numbers are generally classified into 2 main groups - Rational numbers and Irrational numbers.

All the four examples listed here are types of rational numbers only.

Now, positive integers are also called  as whole numbers and natural numbers. So, one point is enough to represent whole numbers and natural numbers.

Also, another point will be required to show integers because integers can be positive and negative and  could include fractions.

Hence, The  fewest number of points we  must plot to have examples of all four sets of numbers given are 2 points.

As we know that positive integers are types of rational numbers and  positive integers are also natural numbers and whole numbers. Therefore all the options given, are positive integers.

The correct question is What is the fewest number of points you must plot in order to have examples of all four sets of​ numbers, including at least one positive and one negative​ integer? Explain.

To which sets do positive integers​ belong?

1. Integers

2.Rational Numbers

3.Natural Numbers

4. Whole numbers

Answer:

In this case the slope of a line perpendicular to the line whose equation is 12x+2y=-12 will be [tex]\frac{1}{6}[/tex]

Step-by-step explanation:

A line has the form:

y = m * x + b

where:

In this case, the line has the form 12*x+2*y=-12

First, you must isolate the variable "y", in order to arrive at the form of the line detailed above:

12*x+2*y=-12

2*y= -12 -12*x

y= (-12 -12*x)÷2

y= (-12)÷2 -(12÷2)*x

y= -6 -6*x

In this case: the slope is -6 and the Y-intercept is -6.

Two lines are perpendicular when they form four equal 90º angles. For two lines to be perpendicular, they must have their slopes inverse and changed sign.

Then, in this case the slope of a line perpendicular to the line whose equation is 12x+2y=-12 will be [tex]\frac{1}{6}[/tex]
