I dont understand how to find cot, sec, and csc

Mathematics
1 answer:
tester [92]2 years ago
8 0

Answer:

Step-by-step explanation:

You just have to take the inverse:

csc θ = 1 / sin θ

sec θ = 1 / cos θ

cot θ = 1 / tan θ

For example:

(a) sin θ = 3/5

cos θ = 4/5

tan θ = 3/4

csc θ = 1 / sin θ = 1 / (3/5) = 5/3

sec θ = 1 / cos θ = 1 / (4/5) = 5/4

cot θ = 1 / tan θ = 1 / (3/4) = 4/3

What is the approximate diameter of a tire that will make 775 complete rotations in one mile? (Note: there are 5280 feet
GalinKa [24]

Answer:

About 2.17 feet.

Step-by-step explanation:

Let <em>d</em> represent the diameter of the tire.

Then the circumference of the tire will be:

C=d\pi

So, the tire will travel dπ miles after one rotation.

After 775 rotations, the total miles traveled should be 5280 feet. Thus:

775(d\pi)=5280

Solve for <em>d:</em>

<em />\displaystyle d=\frac{5280}{775\pi}<em />

Approximate:

d=2.1686...\approx2.17

The circumference of the tire should be about 2.17 feet.

What is the equation for the line that has a slope of 0 and passes through the point (3, 7)?
Harrizon [31]

Answer:

Step-by-step explanation:

PART 1

y=mx+b

m is slope and slope is 0 sooo

y=0x+b

it passes through (3,7)

7=0(3)+b

7=0+b

b=7

y=0x+7

so just y=7

PART 2

y=mx+b

y=1/5x+b

1/2=1/5(-2/3)+b

1/2=-2/15+b

1/2+2/15=b

15/30+4/30=b

19/30=b

y=1/5x+19/30

Evelyn can run 3 miles in 40 minutes. Which equation can be solved to find m, the number of miles Evelyn can run in 60 minutes?
inna [77]

Answer:

m= 4.5 miles

Step-by-step explanation:

Let the number of miles Evelyn can run be m and can be modeled by the equation below

m= kx

Where x Is the Minutes

When m= 3

x= 40

3= k40

k= 3/40

If x= 60

m=3/40(60)

m = (60*3)/40

m= 180/40

m= 4.5 miles
