Can someone do these problems, thank you :-)
Answer:
Step-by-step explanation:
1) 2^2 + 2^2 = c^2
4 + 4 = c^2
8 = c^2
c = sqrt8
2) 2^2 + 3^2 = c^2
4 + 9 = c^2
13 = c^2
c = sqrt13
3) 10^2 + 4^2 = c^2
100 + 8 = c^2
108 = c^2
c = sqrt108
4) 1^2 + 5^2 = c^2
1 + 25 = c^2
26 = c^2
c = sqrt26
5) 3^2 + 1^2 = c^2
9 + 1 = c^2
10 = c^2
c = sqrt 10
6) 9^2 + 9^2 = c^2
81 + 81 = c^2
162 = c^2
c = sqrt162

if cos(x) = -1/4 and tan(x) < 0, what is sin(2x)
Answer:
B is correct: (-sqrt15)/8
Step-by-step explanation:
The value of the x is 104.5° then the value of the sin 2x is -0.49. Then the correct option is B.
What is trigonometry?Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.
If cos(x) = -1/4 and tan(x) < 0
Then the value of the x will be
[tex]\begin{aligned} \cos x &= - \dfrac{1}{4}\\\\x &= \cos^{-1} \dfrac{-1}{4}\\\\x &= 104.5^o \end{aligned}[/tex]
Then the value of the sin 2x will be
[tex]\sin 2x = \sin 2*104.5^o\\\\\sin 2x = \sin 209^o\\\\\sin 2x = -0.4848 \approx 0.49[/tex]

Find all solutions in the interval [0, 2π).
2 sin^2 x = sin x
Answer:
0, π, 2π, π/6 and 5+(π/6)
Step-by-step explanation:
Rearranging, sinx (2 sinx - 1) = 0.
In [0, 2π],sin x = 0 for x = 0, π and 2π.
The other factor = 0 gives the other two solutions.
sin 5+(π/6) = sin (π−(π-6)) = sin π/6 = 1/2.

What is unitary method?It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Steps to Use Unitary Method
First, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.
Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.
Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.
Given:
David completed 12 math problems in 6 minutes.
So, he will solve one math problem in= 6/12 = 1/2 minutes
Now, to complete 50 math problem he needs
=50 x 1/2
=50/2
=25 minutes
Hence, David take 25 minutes to complete 50 math problems.

Wendy walks 2 miles in 22 minutes. She continues to walk at the same rate. How many minutes will it take her to walk 11 miles? Use a double number line to support your answer.
Answer:
121 minutes
Step-by-step explanation:
First, we divide the time by the miles
22 ÷ 2 = 11
So now that we have the unit rate, 1 mile for every 11 minutes, we can multiply 11 (the unit rate minutes) by 11 (the given miles she wants to reach)
11 x 11 = 121
So, in 121 minutes, Wendy can walk 11 miles.
(the double number line will look something like this, but going all the way until 121:11)
The ratio of boys to girls in ms Cunningham’s class is 2 to 3. There are 18 girls in the class. What is the total number of students in her class?
Answer:
30 students
Step-by-step explanation:
you have a ratio, and an unknown amount, so set up a proportion
[tex]\frac{2}{3} = \frac{x}{18}[/tex] I used x because the amount of boys is unknown
so then, cross multiply
(so do 3 times x, and 2 times 18)
[tex]3x=36[/tex]
then divide both sides by 3 to get x by itself, and you get
[tex]x=12[/tex]
this means there are 12 boys in the class. because the problem is asking for the total number of students, add 12 and 18 (the number of boys and girls).
you get 30, so there are 30 students in her class.

24 + f = 54
Show some work
Answer: 30
Step-by-step explanation:
24 + f = 54
f = 54 - 24
f = 30
Answer:
f=30
Step-by-step explanation:
You want to get x by itself on one side, so in order to do that, you need to subtract the 24, and if you do it one side, you need to do it to the other side.
That would give you:
24-24+f=54-24
then simplify it to be:
f=30
