4x=8

Step-by-step explanation:

4x=32

32/4=8

Answer:

x=8

Step-by-step explanation:

4x+25=57

Subtract 25 from both sides:

4x+25-25=57-25

Simplify:

4x=32

Divide both sides by 4:

4x/4=32/4

Simplify:

x=8

Answer:

g(x) = 2f(x) -------> y-intercept at (0,2)

h(x) = f(x)+2 -------> asymptote of y=2

j(x) = f(x+2) -------> y-intercept at (0,4)

m(x) = function decreases as x increases

T(100) represents that the plane flies against the wind at 110mph for 0.714 hours

An approximation is anything that is similar to but not identical to something else. Rounding can be used to approximate a number.

Given that a plane is going to fly 300 miles at a planned speed of 530 mph. The equation is T(W) = ( 300 ) / ( 530 -W).

The value of approximation will be calculated as

T(W) = ( 300 ) / ( 530 -W).

T(110) = ( 300 ) / ( 530 - 110)

T(110) = (300 ) / ( 420)

T(110) = 0.714

T(100) represents that the plane flies against the wind at 110mph for 0.714 hours.

area of circle = pi* r^2

   Area = (3.14)*(5)^2

   area= 78.5 m^2

Step-by-step answer:

The formula for the area of a circle is pi•r², so substitute 5 in for r.

pi•5²

Now, simplify the equation. Use PEMDAS.

There are no Parentheses, so we move on to Exponents.

pi•25

Now, we move to Multiplication.

P.S. If you are using 3.14 for pi, your answer is 78.5; otherwise, your answer is below.

Step-by-step explanation:

slope of red line=(-4-4)/(2-0)=-8/2=-4

eq. of red line is y-4=-4(x-0)

y=-4x+4

put x=0,y=0

0=0+4

which is true if 0<4

so y<-4x+4

The linear inequality represents the graph fr the coordinates (0,4), (2,-4) is y < -4x + 4.

Expressions with linear inequalities compare any two values using inequality symbols like "<",  ">" , "≤" or "≥" These values could be either numerical, algebraic, or both.

Calculation for linear inequality shown by graph:

The coordinates of the straight line are  (0,4), (2,-4).

Substitute the value in equation shown in option C.

y < -4x + 4

For points (0,4), put x = 0 and find y.

y < -4×0 + 4

y = 4 , which is satisfied.

Now consider points (2, -4)

Put x = 2 in the same equation and find y.

y < -4×2 + 4

y = -4 ( which again satisfies the given value for y)

Therefore, the equation y < -4x + 4 satisfies the points given for straight line.

Answer:

[tex]V = 97.911in^3[/tex]

Step-by-step explanation:

Given

Shapes: Cube and Cone

Required

Determine the volume

First we calculate the volume of the cube

[tex]V_1 = l^3[/tex]

Where

l = side length = 5.1

[tex]V_1 = 5.1^3[/tex]

[tex]V_1 = 132.651[/tex]

Next, calculate the volume of the cone using:

[tex]V_2 = \frac{\pi r^2h}{3}[/tex]

Where

h = 5.1

[tex]r = \frac{1}{2} * Diameter[/tex]

[tex]r = \frac{1}{2} * 5.1[/tex]

[tex]r = 2.55[/tex]

So, we have:

[tex]V_2 = \frac{\pi r^2h}{3}[/tex]

[tex]V_2 = \frac{\pi * 2.55^2 * 5.1}{3}[/tex]

[tex]V_2 = \frac{22 * 2.55^2 * 5.1}{7*3}[/tex]

[tex]V_2 = \frac{729.5805}{21}[/tex]

[tex]V_2 = 34.74[/tex]

The volume of the figure is:

[tex]V=V_1 - V_2[/tex]

[tex]V_1 = 132.651[/tex]

[tex]V = 132.651 - 34.74[/tex]

[tex]V = 97.911in^3[/tex]

Answer:

a. 0.4

b. 0.6

c. 0.6493

Step-by-step explanation:

p(checking work email) = p(A) = 0.40

p(staying connected with cell phone) = p(B) = 0.30

p(having laptop) = p(c) = 0.35

p(checking work mail and staying connected with cell phone) = p(AnB) = 0.16

p(neither A,B or C) = p(AuBuC)

= 1-42.8%

= 0.572

p(A|C) = 88% = 0.88

p(C|B) = 70% = 0.7

a. What is the probability that a randomly selected traveler who checks work email also uses a cell phone to stay connected?

p(B|A) = p(AnB)/p(A)

= 0.16/0.4

= 0.4

b. What is the probability that someone who brings a laptop on vacation also uses a cell phone to stay connected?

p(B|C) = P(C|B)p(B)/p(C)

= 0.7x0.3/0.35

= 0.6

c. If the randomly selected traveler checked work email and brought a laptop, what is the probability that he/she uses a cell phone to stay connected?

p(A|BnC)

= P(BnAnC)/p(AnC)

= p(AnC) = p(A|C).p(C)

= 0.88x0.35

= 0.308

p(AnBnC) = p(AuBuC)-p(a)-p(b)+ p(AnB)+p(AnC)+p(BnC)

p(BnC) = 0.7x0.3

= 0.21

p(AnBnC) = 0.572-0.4-0.3-0.35+0.16+0.308+0.21

= 0.2

p(A|BnC) = 0.2/0.308

= 0.6493

Answer:

90 degrees

Step-by-step explanation:

Step 1: State what is known

Notice that the 2 lines cut the square in half and create 4 congruant triangles.  We know a full circle is 360 degrees and the intersection is a perfect circle formed by 4 angles.  We can find the angle AEB by dividing 360 by 4 which gives you 90 degrees

Answer:  Choice A. sin(A) = cos(B)

============================================================

Explanation:

The rule is that sin(A) = cos(B) if and only if A+B = 90.

Note how

Since both result in the same fraction BC/AB, this helps us see why sin(A) = cos(B). Similarly, we can find that cos(A) = sin(B).

In the diagram below, the angles A and B are complementary, meaning they add to 90 degrees. So this trick only applies to right triangles.

The side lengths can be anything you want, as long as you're dealing with a right triangle.

-170/55

-3 1/11

So i think it would be 1/2 (OR .5), or possibly 2 depending on what its asking.

Every number in X can be multiplied by 2 to receive y, or the numbers in y.

The linear equation would be x*2=y, making the linear function 2, UNLESS you want to take Y and DIVIDE it by 2, making it 1/2, linear equasion would be y*.5=x, or y/.5=2 OR y*1/2=x.

Hope this helps, I'm so sorry if its wrong, I'm not too good at linear functions, I'm pretty sure its 1/2.

Answer:

Adult tickets cost $80, children ticket cost $40

Step-by-step explanation:

Given data

let the number of adults be x

and the number of children be y

so

x+y= 40-------------1

The adult tickets

cost 14 dollars and the children’s tickets cost 12 dollars.

14x+ 12y=  720-------2

solve 1 and 2

x+y= 40

14x+ 12y=  720

from 1

x= 40-y

put this in 2 in place of x

14(40-y)+12y= 720

560-14y+12y= 720

collect like terms

-2y= 720-560

-2y= 160

y= -160/2

y= -80

put y= 80 in 1

x+80= 40

x= 40-80

x= -40

Hence Adult tickets cost $80, children ticket cost $40

The answer is 1

Use the discramnt formula

[tex] {b {}^{2} - 4ac } [/tex]

Where a is 81, B is 18, and c is 1

We get

We then get 324-324=0

Which equal 0. Since the discramnt produce 0, the number of solution is one and repeated.
