Step-by-step explanation:

Any feature increases when y-value should likewise be increased for the growth of x-values

Each table will be checked

table-1:

That we can see

-3, -2,-1 , 0, 1,2 x increase

And also -6,-3,-1,1,3,6 y increase 

It increases, thus,

table-2:

That we can see

-3, -2,-1 , 0, 1,2 x increase

But between -2 and 1, it's asking

The y-values of -4,-1,1,4..... are increasing

This increases, thus,

table-3:

Which we can see

-3, -2,-1 , 0, 1,2 x increase

But y changes between -3 and -5 .....this decreases

This does not increase, thus,

table-4:

we can find that the x increase to -3, -2, -1, 0, 1,2 however y rises from 7 to 1.....

This does not increase, thus,

Answer:

[tex]\frac{2}{13}[/tex]

Step-by-step explanation:

Find the probability by dividing the number of fixed gear bikers by the total number of bikers in the parade.

Since there are 8 fixed gear bikers and 52 bikers in total, this will be found by dividing 8 by 52.

So, the probability as a fraction is [tex]\frac{8}{52}[/tex]

This can be simplified by dividing both the numerator and denominator by 4:

= [tex]\frac{2}{13}[/tex]

So, the probability is [tex]\frac{2}{13}[/tex]

Answer:

None of these

Step-by-step explanation:

Corresponding, alternate interior, and same side interior angles only occur in a set of parallel lines. In figure f, none of the lines are parallel. Straight angles are defined as angles that make up one side of the line, or 180 degrees, and as the picture clearly shows, this is not the case.

Answer:

a.straight

b.corresponding

c.alternate interior

d.none of these

e.none of these

f.none of these

g.none of these

h.none of these

i.same side interior

Answer:

-6 < x < -5

Step-by-step explanation:

(x+7)^5 = 20

Raise both sides to the (1/5) power

x + 7 = 1.820564203

Subtract 7 from both sides

x = -5.179435797

-6 < x < -5

Answer:

P = A - 0.2P

Step-by-step explanation:

A = P + Prt

Where,

A = Total amount in an account earning simple interest

P = principal

r = rate

t = time

A = P + Prt

In terms of Payment

P = A - Prt

Holly:

r = 4% = 0.04

t = 5 years

P = A - Prt

= A - (P * 0.04 * 5)

= A - 0.2P

P = A - 0.2P

Answer:

x( x^2+4)

Step-by-step explanation:

factor out x from the expression

xx (x^2+4)

than your answer is x( x^2+4)

Answer:

[tex] x(x + 2)(x + 2)[/tex]

Step-by-step explanation:

as the x is the common factor...get x out

[tex] {x}^{3} + 4x[/tex]

[tex]x( {x}^{2} + 4)[/tex]

Then

[tex]x( {x}^{2} + 4) \\ x( {x}^{2} + {2}^{2} ) \\ x(x + 2)(x + 2)[/tex]

[tex]5820[/tex] square inches

Step-by-step explanation:

For the rectangular prism in the middle:

[tex]24*30=720*2=1140[/tex]

[tex]10*30=300*2=600[/tex]

[tex]1140+600=1740[/tex]

For the left triangular prism:

[tex]10*24=240[/tex]

[tex]26*30=780[/tex]

[tex]24*30=720[/tex]

[tex]10*30=300[/tex]

[tex]240+780+720+300=2040[/tex]

For the other right triangular prism, it's the same.

Let's add now to find the surface for the whole ramp.

[tex]1740+2040+2040=5820[/tex]

Answer:

x = 4

Step-by-step explanation:

I think this is correct

Answer:

An algebraic expression is a type of expression that contains a variable or variables.

Answer:

4

Step-by-step explanation:

4 * 2=8. Don't really know how else to explain it

Find the full area of the triangle, and take away the area of the rectangle inside it to get the area of the shaded bits.

Area of whole triangle = (base x height) / 2 = (24 x 18) / 2 = 216

Area of rectangle = 6 x 20 = 120

Area of shaded region = 216 - 120 = 96

So 96 is the answer

Answer:

x = 26

Step-by-step explanation:

x+64 is a right angle

x+64 = 90

Subtract 64 from each side

x = 90-64

x = 26

Answer:

x = 26°.

Step-by-step explanation:

This is a complementary angle. Complementary angles are two angles that have a sum of 90°.

[tex]90-64=26.[/tex]

[tex]26+64=90.[/tex]

[tex]x=26.[/tex]

Answer:

m<ABC  = 51degrees

Step-by-step explanation:

The angle at the vertex is half the difference of the angles at the intercepted arcs. Hence;

m<B = 1/2 (arcAD - arcAC)

<ABC = 1/2(17x + 2 -(7x - 10°))

4x + 15 = 1/2(17x-7x+2+10)

2(4x+15) = 10x+12

8x + 30 = 10x+12

8x-10x = 12-30

-2x = -18

x = 18/2

x = 9

Get m<ABC

m<ABC = 4x + 15

m<ABC = 4(9) + 15

m<ABC = 36 + 15

m<ABC  = 51degrees

The measure of angle ∠ABC  = 51 degree.

Since we know that,

For a circle,

The angle at the vertex is half the difference of the angles at the intercepted arcs.

Therefore,

m∠ABD = 1/2 (arcAD - arcAC)

⇒   ∠ABC = (1/2)(17x + 2 -(7x - 10°))

⇒  4x + 15 = (1/2)(17x-7x+2+10)

⇒2(4x+15) = 10x+12

⇒ 8x + 30 = 10x+12

⇒   8x-10x = 12-30

⇒         -2x = -18

⇒             x = 18/2

⇒             x = 9

Get m∠ABC

⇒ m∠ABC = 4x + 15

⇒ m∠ABC = 4(9) + 15

⇒ m∠ABC = 36 + 15

⇒ m∠ABC  = 51 degree

Step-by-step explanation:

This problem is a bit tedious to work out all at once. The first student opens every locker so lockers 1 to 50 are open.

The second student closes every two lockers so every even locker is closed while every odd locker is open. This will repeat over and over and will take too long.

An alternative for this would be checking the factors of each number. For example, 4 has three unique factors, which are 1, 2 and 4. The number of unique factors determine whether the locker is open or closed. In this case, locker 4 will be open after all 50 students finished. Student 1 opens locker 4, student 2 closes locker 4, student 3 doesn't change locker 4 and student 4 opens locker 4. However, students 5 to 50 will never change the locker.

I can't help put all of the answers at once but this should help.

Round this value however you need to. The exact length is sqrt(319)

In other words, sqrt(319) = 17.8606

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

Work Shown:

Apply the pythagorean theorem to solve for b.

a^2+b^2 = c^2

9^2 + b^2 = 20^2

81 + b^2 = 400

b^2 = 400-81

b^2 = 319

b = sqrt(319)

b = 17.8606 which is approximate

I'm going with the approximate value it makes more sense to do so in this case. Saying "the length is sqrt(319)" to someone not familiar with math, would probably not convey just how long the third side must be. Round the value in bold however you need to.

Answer:

P = -31

Step-by-step explanation:

-1 + 14p = -435

Remove the -1 by adding it from both sides.

14p = -434

Remove the 14 by dividing it from both sides.

p = -434/14

p = -31

Answer:

-31

Step-by-step explanation:

-1+14p=-435

14p=-435-(-1)

14p=-435+1

14p=-434

p=-434/14

p=-31
