How to find the measure of yz

Mathematics

stira [4]3 years ago

Use the Law of Sines (sina/A=sinb/B=sinc/C for any triangle)

YZ/sin30=50/sin90

YZ=50sin30   (sin90=1 :P)

YZ=25m

Use the 30,60,90° triangle ratios 1, √3, 2

YZ/1=50/2

YZ=25m

Using the Pythagorean Theorem....

(2*25)^2=YZ^2+(√3*YZ)^2

2500=YZ^2+3YZ^2

2500=4YZ^2

625=YZ^2

25m=YZ

Answer:

P(roll a number less than 5)= 4/6= 2/3

Step-by-step explanation:

*A dice has 6 faces 1,2,3,4,5,6

*1,3,5 are faces with odd numbers

*2,4,6 are faces with even numbers

*we have four numbers that are less than 5: 1,2,3,4

so i would say the probability to roll a dice with a number less

than 5 is P=4/6=2/3

Using f(x) = 4x + 6 with the domain of {-1,0,2}, find the range
konstantin123 [22]
The range is the output of the function, and there are many ways to find it and write it. Let's find it first by plugging in all the domain values (domain means input) into the function:
f(-1) = 4(-1)+6=-4+6=2
f(0) = 4(0)+6=0+6=6
f(2) = 4(2)+6 = 8+6=14

We have all of our values. We can either write the range as:
{2, 6, 14}

or, subtract the smallest value from the largest one:
14-2=12

So, there are those ways to write it, there are more, but I think you should stick with the first way because that's how the problem was presented to you. If you have any questions, hmu!

4x-5 - 2x-1
3241004551 [841]

Answer:

\frac{5x - 8}{3}

Step-by-step explanation:

Find the LCM of the denominators and then solve:

\frac{4x - 5}{2} - \frac{2x - 1}{6} \\\\

\frac{4x - 5}{2} - \frac{2x - 1}{6} \\\\\frac{3(4x - 5) - 2x - 1}{6} \\\\\frac{12x - 15 - 2x - 1}{6}\\\\\frac{10x - 16}{6}\\\\ \frac{2(5x - 8)}{2 * 3} \\\\ \frac{5x - 8}{3}
