Answer:
f(3) = - 38
Step-by-step explanation:
f(2) = 3 f(2 - 1) - 5 = 3 f(1) - 5 = 3(-2) - 5 = -6 - 5 = -11
f(3) = 3 f(3 - 1) - 5 = 3 f(2) - 5 = 3(-11) - 5 = - 33 - 5 = - 38

Fairview is 15 kilometers due north of the airport, and Lowell is due east of the airport. If the
distance between Fairview and Lowell is 17 kilometers, how far is Lowell from the airport?
Answer:
8km
Step-by-step explanation:
The three points form a right-angled triangle with 15km as the height and 17km as the hypotenuse.
To find the distance between Lowell and the port which is the base use the pythagorean theorem.
=√17² - 15²
=8km

Solve for x. Round your answer to the nearest tenth. HELPPPPP!
Answer:
x = 32.6°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin x = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{7}{13}[/tex] , then
x = [tex]sin^{-1}[/tex] ([tex]\frac{7}{13}[/tex] ) ≈ 32.6° ( to the nearest tenth )

translation
Answer:
it's a translation
Step-by-step explanation:
it just moved (3,0). If it were a rotation the y-axis wouldn't be the same. If it were a reflection you would be able to flip the blue triangle onto the red triangle.
(c) Rashid has 210g of cocoa powder and plenty of the other ingredients.
He says that he can make at least 75 cupcakes.
Is he correct?
Explain your reasoning.
Answer:
He is incorrect. He would need 225g of cocoa powder
Step-by-step explanation:
1. Lets calculate how much powder do we need per one cupcake, so 60 divided by 20, since 60g makes 20 cupcakes, 60/20 = we get 3g of cocoa powder per one cupcake.
2. Now we can multiply that by 75, 75*3=225, and 225g is more than 210g

Nina mixed 2 ⅛ pounds of apples, 1 ½ pounds of berries, and 1 ¼ pounds of grapes for a salad. She set aside ⅓ of the slad for dinner and put the rest in a container for later. How many pounds of salad did she put in the container?
Answer: [tex]\dfrac{13}{4}\ \text{or}\ 3\ \dfrac{1}{4}\ \text{Pounds}[/tex]
Step-by-step explanation:
Given
Nina mixed [tex]2\ \frac{1}{8}[/tex] pounds of apples, [tex]1\ \frac{1}{2}[/tex] pounds of berries, and [tex]1\ \frac{1}{4}[/tex] pounds of grapes.
Total salad is
[tex]\Rightarrow \dfrac{2\times 8+1}{8}+\dfrac{1\times 2+1}{2}+\dfrac{1\times 4+1}{4}\\\\\Rightarrow \dfrac{17}{8}+\dfrac{3}{2}+\dfrac{5}{4}=\dfrac{17+12+10}{8}\\\\\Rightarrow \dfrac{39}{8}\ \text{Pounds}[/tex]
Now, one-third of the salad is kept aside and the remaining is put in the container.

Answer:
There are 42 dogs and 105 cats at the shelter. To find the number of rabbits, subtract these numbers from the total number of animals at the shelter. So there are 21 rabbits at the shelter.
Step-by-step explanation:
Because there are 168 animals at the shelter and [tex]\frac{1}{4}[/tex] of the animals are dogs, you can infer that there are [tex]\frac{168}{4}[/tex] or 42 dogs at the shelter. The question says that [tex]\frac{5}{6}[/tex] of the remaining animals are cats, which you can get two things from this statement: #1, [tex]\frac{5}{6}[/tex] of the remaining animals (not including dogs) are cats in the shelter. #2, [tex]\frac{1}{6}[/tex] of the remaining animals (not including dogs) are rabbits in the shelter, since that is the remaining number of animals left that aren't cats or dogs. Using this, you can get the number of cats is the number of dogs subtracted by the total number of animals at the shelter and multiplied by [tex]\frac{5}{6}[/tex], which would be [tex]\frac{5}{6}[/tex](168 - 42) = [tex]\frac{5}{6}[/tex]*126 = 5 * 21 = 105 cats at the animal shelter. Since the number of rabbits is [tex]\frac{1}{5}[/tex] the number of cats in the shelter ([tex]\frac{5}{6}[/tex] = [tex]\frac{1}{6}[/tex] * 5), that means there are [tex]\frac{105}{5}[/tex] or 21 rabbits at the animal shelter, and that we'd need to subtract the number of cats and dogs from the total number of animals at the shelter to find the number of rabbits.
What is the probability of flipping a coin 3times and getting 3tailsin a row?
Answer:
1/8
Step-by-step explanation:
The probability of getting tails on a single flip is 1/2.
Each of the flips is an independent event so you must multiply the probability of getting tails on each flip together.
So, your answer will look like this
[tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] ; which equals;
1/8
Answer:
1/8
Step-by-step explanation:
To calculate the probability you have to name all possible results first. If you mark a result of a single coin flip as H for heads or T for tails all results of 3 flips can be written as:
Ω = { ( H , H , H ) , ( H , H , T ) , ( H , T , H) , ( H , T , T ) , ( T , H , H ) , ( T , H , T ) , ( T ,T , H ) , ( T , T , T ) }
Each triplet contains results on 1st, 2 nd and 3 rd coin. So you can see that in total there are 8 elementary events in Ω.
| Ω | = 8
Now we have to define event A of getting tails three times.
The only elementary event which satisfies this condition is ( T , T , T ) so we can write that:
A = { ( T, T , T ) }
| A | = 1
Now according to the (classic) definition of probability we can write, that:
P ( A ) = | A|/ | Ω | = 1 /8
So finally we can write the answer:
The Probability of getting 3 tails in 3 coin flips is 1 /8 .
Find the volume of the cone in terms of pi. 405TT cm3 324TT cm3
405TT cm3 72TT cm3
The volume of the cone in terms of pi is 324π cubic cm.
What is volume of cone?Volume in mathematics describes how much space a three-dimensional item takes up. It is a measurement of the object's capacity, or the volume of fluid it can store. Typically, cubic units like cubic metres (m3) or cubic centimetres are used to determine an object's volume.
A three-dimensional object's shape affects the formula used to determine its volume. A rectangular prism's volume, for instance, can be determined by multiplying its length, width, and height.
The volume of the cone is given by the formula:
V = (1/3)πr²h
Now, for r = 9 and h = 12 we have:
V = (1/3)πr²h
V = (1/3)π(9²)(12)
V = 324π cubic cm
Hence, the volume of the cone in terms of pi is 324π cubic cm.
