Find sin0, cot0, and csc0, where 0 is the angle shown in the figure. Give exact values, not decimal approximations. BRANLIEST!​

Mathematics
1 answer:
Hoochie [10]3 years ago
7 0

Answer:

Sin0 = 25/43

cot0 = 7/5

csc0 = 43/35

Step-by-step explanation:

X^2 = 5^2 + 7^2

X^2 = 25 +49

X^2 = 74

X = sqrt (74) = 8.6

Opp = 5

Adj = 7

Hypo = 8.6

sin0 = opp/Hypo = 5/8.6

Sin0 = 50/86 = 25/43

cot0 = 1/tan0 = adj/opp

cot0 = 7/5

csc0 = 1/cos0 = hypo/adj

csc0 = 8.6/7 = 86/70 = 43/35

Sofia places 26 tiles representing each letter of the alphabet into a bag. Five of the tiles represent the vowels A, E, I, O, an
mars1129 [50]

Answer:

42 times.

Step-by-step explanation:

The number of total alphabet = 26 tiles

The number of vowels = 5

The number of consonant = 26 - 5 = 21

Sofia will randomly select 1 tile from the bag and without replacement select another tile from the bag.

The probability to select consonant at first time = 21/26

Total tiles after the first selection = 26 - 1 = 25

The probability to select vowels at second time = 5/25

The probability to select consonant and vowels = \frac{21}{26} *\frac{5}{25} =\frac{21}{130}

Sofia will draw two tiles from the bag 260 times.

The prediction for the number of times Sofia will select a consonant tile and a vowel tile = \frac{21}{130} *260=42 \ times

What is the solution to the equation startfraction y over y minus 4 endfraction minus startfraction 4 over y 4 endfraction = sta
zmey [24]

The solution to the given equation is 4 and -4.

<h3>What is a fraction?</h3>

Fractions are the numerical values that are a part of the whole.

A whole can be an object or a group of objects.

The given equation is;

\rm \dfrac{y}{y - 4}- \dfrac{4}{y + 4}= \dfrac{32}{y^2- 16}

A fraction is used to represent the portion/part of the whole thing.

The solution of the fraction is determined in the following steps given below.

\rm \dfrac{y}{y - 4}- \dfrac{4}{y + 4}= \dfrac{32}{y^2- 16}\\\\\rm \dfrac{y(y+4)-4(y-4)}{(y - 4)(y+4)}= \dfrac{32}{(y-4)(y+4)}\\\\y^2+4y-4y+16=32\\\\y^2=32-16\\\\y^2=16\\\\y=\pm 4

Hence the solution to the given equation is 4 and -4.

Find two numbers between 1.4142133 and 1.41422
Naddik [55]

Hey there! I'm happy to help!

To find the number halfway between two numbers, you simply add them and then divide by two.

1.4142133+1.41422=2.8284333

2.8284333/2=1.41421665

That is one number in between these two. Now, we can find the number in between the middle number and the second number. This is another number in between our two numbers.

(1.41421665+1.41422)/2=1.414218325

You could keep on doing this and find tons of numbers in between these two.

Therefore, two numbers between 1.4142133 and 1.41422 are 1.41421665 and 1.414218325.

Have a wonderful day! :D
