Answer:

f(1) = 36

f(n) = f(n-1) - 5.

Step-by-step explanation:

f(1) = 41 - 5 = 36.

f(n) = f(n - 1) - 5.

Answer:

No, the sides of a triangle cannot have the lengths 2, 5, and 5.

Step-by-step explanation:

Using the right triangle formula, aka. the Pythagorean Theorem, which is [tex]a^{2}+b^{2}=c^{2}[/tex] we need to substitute the sides given with the variables.

[tex]2^{2} +5^{2} =5^{2}[/tex]

Simply to [tex]4+25=25[/tex].

Add 4 to 25.

29 [tex]\neq[/tex] 25

Answer:

No....

Step-by-step explanation:

it cannot because triangle throrem says that the 2 smaller sides of of triangle must be greater than one side. 2+5 = 7, and 7>5.

4 inches is your answer! God bless!!

The radius of each semicircle in this composite figure is 1 in.

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares whcihh cover a closed figure's surface is its area.

We have, Radius of semicircle = 2 in

So, Area of semicircle = πr²/2

                                    = 3.14/2 x 2/2 x 2 /2

                                    = 1.57 x 1 x 1

                                    = 1.57 mm²

So, the area of the semicircle is 1.57 mm².

Therefore, Radius = 1 in

Answer:

x=12

Step-by-step explanation:

90 = x + 42 + 3x

48 = x + 3x

48 = 4x

12 = x

Answer:

x = 12

Step-by-step explanation:

Since we are given a right angle, we can say that:

sum of all angles = 90 degrees

x + 42 + 3x = 90

4x = 48

x = 12

So, x is equal to 12 degrees!

Step-by-step explanation:

mx+y=b

m=slope

-3x+y = 8, m=3, your welcome

Answer:

A

Step-by-step explanation:

These two coordinates in (x,y) form have the same value for x, so they only differ in the y-value. That means if we subtract the y-values, that’s the vertical distance!

-8 - 3 = -11

(It helps me to think of this as -8 + -3.) They’re 11 units apart: think of it like a absolute value.

So the answer is A. 11

Answer:

23

Step-by-step explanation:

Simplify the following:

(-66)/(-3) - 4 - -5

The gcd of -66 and -3 is -3, so (-66)/(-3) = (-3×22)/(-3×1) = (-3)/(-3)×22 = 22:

22 - 4 - -5

-(-5) = 5:

22 - 4 + 5

22 + 5 = 27:

27 - 4

| 2 | 7

- | | 4

| 2 | 3:

Answer:

Step 2

Step-by-step explanation:

here are the steps to 8d=72

[tex]\frac{8d}{8}[/tex] = [tex]\frac{72}{8}[/tex]

d = 9

Derek did step to wrong because he divided wrong. 72/8 is not 8.

its 9.

therefore Derek did step 2 is wrong

Explanation: The inputs, or reactants, of cellular respiration are glucose and oxygen. The outputs, or products, of cellular respiration are water, carbon dioxide

Answer:

The answer would be one triangle. it is only one triangle because the sum of the angles of any triangle have to equal 180°. So if you add all of the angles you gave us, that would equal 180°.

Answer:

D?

Step-by-step explanation:

As per probability, the fair way to pick one of three students is to roll a number cube. If 1 or 6 comes up, pick Bella. If 2 or 5 comes up, pick Chrissie. If any other number comes up, pick Destiny.

Probability indicates the chance of happening an event or incident.

For option-A, the probability to pick any one student is not equal for all of them.

For option-B, the probability of the tallest student is more to be picked.

For option-C, the probability for all the students to be picked are equal.

For option-D, the probability to pick any one student is not equal for all of them.

Therefore, option-C is the fair way to do.

Answer:

[tex] p =\frac{25}{40+20+25+15}= \frac{25}{100}= 0.25[/tex]

So then the probability for this case would be 0.25 or 25%

Step-by-step explanation:

For this case we have 40 black , 20 yellow, 25 orange, and 15 purple wristbands

And we want to find the probability that Melanie will select an orange wristband so we can use the definition of probability:

[tex] p =\frac{successes}{total}[/tex]

And replacing we got:

[tex] p =\frac{25}{40+20+25+15}= \frac{25}{100}= 0.25[/tex]

So then the probability for this case would be 0.25 or 25%

Answer:

Step-by-step explanation:

length = 25 in

Perimeter = 86 in

2*(length + width) = 86

2*(25 + N) = 86

Divide both sides by 2

25 + N = 86/2

25 + N = 43

Subtract 25 from both sides

25 + N - 25 = 43 - 25

N = 18

Answer:

46x + 23 = 46x +23

Step-by-step explanation:

46x - 23 = 46x + 23

Subtract 46x from each side

-23 = 23

This is not true so there are no solutions

-46x + 23 = 46x + 23

Add 46x to each side

23 = 96x +23

Subtract 23 from each side

0 = 96x

x=0   one solution

46x + 23 = 46x +23

Subtract 46x from each side

23 = 23

This is always true so there are infinite solutions

-46x - 23 = 46x + 23

add 46x to each side

-23 = 96x +23

subtract 23 from each side

-46 = 96x

x = -1/2

Answer:There are zero interception.

Step-by-step explanation:

The equation to Line U: is  y=-3x +19  and the equation to line V  is  y=-3x +14

So as you can see ,the lines have the same slopes but different y-intercepts.This means the lines are going to be parallel when being graph.Parallel lines never cross or intersect so there  is no points of intersection.
