How do I graph y=3tanx?

Answer: B

Step-by-step explanation:

Answer:

Step-by-step explanation:

(f + g)(2) = 2(2) + 3 + (2)^2 - 1 = 10

(f - g)(4) = 2(4) + 3 - (4)^2 + 1 = -4

(f / g)(2) = (2(2) + 3) / ((2)^2 -1) = 7/3

(f * g)(1) = (2+3)(1-1) = 0

Answer:

30

Step-by-step explanation:

1 * 6 = 6

5 * 6 = 30

6:30

When you reduce it will be back to 1:5

Answer:

$7.2 A.t a wholesale

Step-by-step explanation:

80%of $36

The mathematical order is :

80÷100×36

80÷100×36=$28.8

When we have found the 80% that is added

We subtract it from the retail price.

$36-$28=$7.2

At the end we are left with our wholesale prices.

Answer:

21 inches

Step-by-step explanation:

Answer:

Solution given:

perpendicular distance =height [p]=40m

base or horizontal distance [b]=198m

Hypotenuse or zip line [h]=?

Now

By using Pythagoras law

h²=p²+b²

h²=40²+198²

h=√40804

h=202m

So the Zip line is 202m long.

Answer:1444.4

Step-by-step explanation:

part 1:To start do 10 times 10 then multiply that by 3.14 then multiply that again by 2.

Part 2:then multiply the radius by the height and then multiply that number by 3.14 then multiply it by 2.

Part 3: then add both together

Answer:

1,444.4

Explanation:

S=2πr2+ 2πrh

S=628+816.4

S=1,444.4

Answer:

58° = measure of arc AC

Step-by-step explanation:

The measure of an angle formed by 2 chords is equal to 1/2 the sum of the measures of the intercepted arcs.

65 = (measure of arc AC + measure of arc BD)/2

     =  (measure of arc AC + 72)/2

130 = measure of arc AC + 72

58° = measure of arc AC

Answer:

$16.70

Step-by-step explanation:

9.5 miles / .25 = 38

The first mile is 1.25 so we do this

37 * .35 = 12.95

12.95 + 1.25 = 14.2

14.2 + 1.25 + 1.25(two additional passengers) = 16.70

Answer:

23 Ft

Step-by-step explanation:

Answer:

c = 24.34

Step-by-step explanation:

Here, we can use the cosine rule

Generally, we have this as:

a^2 = b^2 + c^2 - 2bcCos A

12^2 = 14^2 + c^2 - 2(14)Cos 19

144 = 196 + c^2 - 26.5c

c^2 - 26.5c + 196-144 = 0

c^2 - 26.5c + 52 = 0

We can use the quadratic formula here

and that is;

{-(-26.5) ± √(-26.5)^2 -4(1)(52)}/2

(26.5 + 22.23)/2 or (26.5 - 22.23)/2

24.37 or 2.135

By approximation c = 24.34 will be correct

Answer:

x= -1, y=1

Step-by-step explanation:

First label the 2 equations.

7x +6y= -1 -----(1)

-x +2y= 3 -----(2)

Then choose which term you would like to eliminate. To eliminate the y term, multiply equation (2) by 3 such that the coefficient of y is 6.

(2) ×3:

-3x +6y= 9 -----(3)

Since the coefficient of y is positive 6 in both equations, subtract one equation from the other.

(3) -(1):

-3x +6y -(7x +6y)= 9 -(-1)

Expand:

-3x +6y -7x -6y= 9 +1

-10x= 10

x= 10 ÷(-10)

x= -1

Substitute x= -1 into (2):

-(-1) +2y= 3

1 +2y= 3

2y= 3 -1

2y= 2

y= 2 ÷2

y= 1

------------------------------------------------------------

2nd method: eliminating the x term

(2) ×7:

-7x +14y= 21 -----(3)

Since the coefficient of y in equation (1) is a positive 7, while that in equation (3) is a negative 7, add the 2 equations together to eliminate the x term.

(1) +(3):

7x +6y -7x +14y= -1 +21

20y= 20

y= 20 ÷20

y= 1

Substitute y= 1 into (2):

-x +2(1)= 3

-x +2= 3

-x= 3 -2

-x= 1

x= -1

Answer:

21

Answer: -1 8/15

Step-by-step explanation:

First turn it to improper fraction

29/5 — 22/3

87–110/15. (Here make 15 the denominator since both 3 and 5 goes in 15.

—23/15

—1 8/15

Answer:

343pi^3

Step-by-step explanation:

Volume of a cone = 1/3(nr^2h)

n = 22/7

r = radius  

h = height

Base area = area of a circle

Area of a circle = πr²

49 pi = πr²

r² = 49

r = 7

h = 7 x 3 = 21

volume = 1/3 x 21 x 7^2 = 343pi

Answer:

C, 21 students

Step-by-step explanation:

if you count out each dot plotted it equal 21 people

Answer:

C

Step-by-step explanation:

Because if we multiply by 2 both member we have

(x-12)(x-4)= 0

A product has a result that is equal to iif at least one of its factor is equal to 0, so we can solve this two equations:

x-12 = 0

x = 12

x-4 = 0

x = 4
