This graph shows the solution to which inequality?

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identities

cosec x = [tex]\frac{1}{sinx}[/tex] , cot x = [tex]\frac{cosx}{sinx}[/tex]

Consider the left side

[tex]\frac{(1+cosA)^2-(1-cosA)^2}{sin^2A}[/tex] ← expand and simplify numerator

= [tex]\frac{1+2cosA+cos^2A-(1-2cosA+cos^2A}{sin^2A}[/tex]

= [tex]\frac{1+2cosA+cos^2A-1+2cosA-cos^2A}{sin^2A}[/tex]

= [tex]\frac{4cosA}{sin^2A}[/tex]

= 4 × [tex]\frac{1}{sinA}[/tex] × [tex]\frac{cosA}{sinA}[/tex]

= 4cosecAcotA

= right side,  thus proven

Answer:

i think in order it would go c, b, d

Answer:

1. D

2. B

3. A

Step-by-step explanation:

1. This is the only graph with a negative y-int.

2. Proportional means the graph has a y-int of zero and this graph is the only graph that does.

3. This is the only graph with a positive slope.

Answer:

Each donut will cost $2.

Step-by-step explanation:

A dozen of donuts = 12 donuts

$24 ÷ 12 = $2

Answer:

its 3.05

Step-by-step explanation:

The coordinates of A will be at (-10, -5) when the transformation (x,y) → (x + 10, y + 5) is  performed on point A.

Given the coordinate of the resulting image after the transformation is A'(0, 0). We need to get the coordinate of the original image A.

Since the transformation (x,y) → (x + 10, y + 5) is performed on A.

A = (0 - 10, 0 - 5)

If we are going from the pre-image to the image, we will translate to the left and downwards

A = (-10, -5)

Hence the coordinates of A will be at (-10, -5)

Answer:the domain is all real numbers it also like the x value and the range is all y value

Step-by-step explanation:

Answer:

The domain is the set of values of "x" for which the function has meaning.

Based on my knowledge x can be any real number except for zero.

The range of f(x) is the same as finding all that y could be.

The range of f(x) is all the y values where there is a number x with y = f(x).

Answer:

x intercept is -5

y intercept is 4

Answer:

Step-by-step explanation:

-4x +  5y = 20

Divide the equation by 20

[tex]\frac{-4x}{20}+\frac{5y}{20} = \frac{20}{20}\\\\\\\frac{x}{-5}+\frac{y}{4}=1\\\\[/tex]

x intercept =  (-5)

y intercept = 4

n=96\8

n= 9

14-a=5

-a=5-14

-a=-9

Answer:

0.48

Step-by-step explanation:

Just move back one decimal point of 4.8

Answer: I just did this one lol

Step-by-step explanation:

10 percent *4.8 =

(10:100)*4.8 =

(10*4.8):100 =

48:100 = 0.48

Now we have: 10 percent of 4.8 = 0.48

Question: What is 10 percent of 4.8?

Percentage solution with steps:

Step 1: Our output value is 4.8.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$4.8=100\%$.

Step 4: Similarly, $x=10\%$.

Step 5: This results in a pair of simple equations:

$4.8=100\%(1)$.

$x=10\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{4.8}{x}=\frac{100\%}{10\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{4.8}=\frac{10}{100}$

$ x=0.48$

Answer: Angle 2 is 110

Angle 3 is 70

Angle 4 is 70

Step-by-step explanation:

:)

Step-by-step explanation:

angle 2= 110

angle 3=70

angle 4=70

Sum of all angles in a triangle = 180°

Which means :-

∠1 + ∠2 + ∠3 = 180°

[tex]2x + x + x + 8 = 180°[/tex]

[tex]4x + 8 = 180°[/tex]

[tex]4x = 180 - 8[/tex]

[tex]4x = 172[/tex]

[tex]x = \frac{172}{4} [/tex]

[tex]x = 43[/tex]

Angle 1 :-

= 2x

= 2 × 43

Angle 2 :-

= x

Angle 3 :-

= x + 8

= 43 + 8

[tex]therefore \: , \: the \: value \: of \: x = 43°[/tex]

2.) m<7 and m<9=66, m<8=114

note: brainliest would be appreciated.

Step-by-step explanation:

x - Ernie, y - Kaylin, z - Tria

x = y + 121.50

z = 3y - 35

x + y + z = 579

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

z = 3 y - 35      =>   - 3 y + z = -35

y + 121.50 + y + z = 579

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

- 3 y + z = - 35        / · ( -1 )

 2 y + z = 457.50     (we will use the elimination method) 

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

3 y - z = 35

2 y + z = 457.50

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

5 y = 492.5,            y = 492.5 : 5 = 98.5

z = 3 · 98.5 - 35

z = 260.5

Tria earned $260.5

Answer:

Number of drummers in original ensemble  [tex]=3[/tex]

Number of flutists in original ensemble [tex]=21[/tex]

Step-by-step explanation:

The ratio of flutists to drummers is [tex]7:1[/tex]

Let number of flutists and drummers be [tex]7x[/tex] and [tex]x[/tex].

As 2 drummers join the group and 6 flutists quit,

Number of drummers = [tex]x+2[/tex]

Number of flutists = [tex]7x-6[/tex]

New ratio of flutists to drummers = [tex]3:1[/tex]

So,

[tex]\frac{7x-6}{x+2}=\frac{3}{1}\\ 7x-6=3(x+2)\\7x-6=3x+6\\7x-3x=6+6\\4x=12\\x=3[/tex]

So,

Number of drummers in original ensemble  [tex]=x=3[/tex]

Number of flutists in original ensemble [tex]=7x=7(3)=21[/tex]

Answer:

As a fraction it's ¼, as a decimal it's 0.25 and as a percentage it's 25%

Answer:

= 1/5

.2

20%

Step-by-step explanation:

In the bag there are 5 pennies, 4 nickels , 5 dimes, 2 quarters

We add 1 penny 2 dimes and 1 quarter

Now in the bag

6 pennies, 4 nickels, 7 dimes, 3 quarters

for a total of 20 coins

P ( nickel) = number of nickels / total

                 = 4/20 = 1/5

                  .2

                   20%

She is more likely to draw a nickel before the 1 penny 2 dimes and 1 quarter because there are fewer coins in the bag that are not nickels

Answer:

Total amount spent [tex]=\$73.5[/tex]

If they decide to split the bill, amount paid by each of the person  [tex]=\$15.25[/tex]

Step-by-step explanation:

Cost of each movie ticket = $11

Cost of 5 tickets = 5(11)= 55

Cost of each packet of popcorns = $3.75

Cost of two packets of popcorns = $2(3.75) = $7.5

Cost of each soda = $2.75

Cost of five sodas = $5(2.75) = $13.75

Total number of persons (Rachel and four friends) = 5

Total amount spent [tex]=11(5)+2(3.75)+5(2.75)=55+7.5+13.75=\$76.25[/tex]

If they decide to split the bill, amount paid by each of the person = [tex]\frac{76.25}{5}=\$15.25[/tex]
