Simplify [tex]\frac{sin^2x+cos^2x}{sin x}[/tex]

Answer:

The answer would be .39

Step-by-step explanation:

So first we have to know the eqation to finding the area of a semicircle, this would be:

2r x π  ÷ 2 (r stands for radius)

Ok so since our diameter is 2 we need to divide that in half to find our radius which we would then get .5

And then you we would fill in the blanks and make our eqaution :

2 x 0.5 x 3.14  ÷ 2 which would give us the answer of .39

i have no idea if this is right so pls lmk!

Applying the distance formula, the perimeter of the plot of land, rounded to the nearest tenth, is: 482.8 ft.

Distance formula is given as: [tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex].

Name the coordinates of the plot of and as follows:

A (0, 120)

B (140, 100)

C (140, 20)

D (0, 0)

Perimeter of the plot of land = AB + BC + CD + AD

AD = |120 - 0| = 120 ft

BC = |100 - 20| = 80 ft

Use the distance formula to find AB and CD:

AB = √[(140−0)² + (100−120)²]

AB = √20000

AB = 141.4 ft

CD = √[(140−0)² + (20−0)²]

CD= √20000

CD = 141.4 ft

Perimeter of the plot of land = 141.4 + 141.4 + 120 + 80 = 482.8 ft.

Answer:

2,048 cm

Step-by-step explanation:

There are 4 weeks in a month, and the fish doubles in length every week

Let's put this into a table: (attached picture)

First we start off at 0.5 cm in week 0 (this is week 0 because you just bought the fish).

Then, the length doubles in week 1, so the fish becomes 1 cm.

In week 2, the fish's length doubles again to become 2 cm.

In week 3, the length doubles to become 4 cm.

So on, and so on until we reach a length of 2048 cm.

Therefore, after 3 months the fish's length will be 2,048 cm.

Because if the bottom one is 4 yards then the top one needs to be 4 yards.

Answer:

Probability = 9/25

This is 36%

Step-by-step explanation:

To find the probability take the total number of possibilities (25 marbles--all of them) put that number on the bottom of a fraction. Then put the number of ways that outcome can happen (9 blue and black) and put that on top of the fraction.

Probability(event)

= specific/total

Probability(blu&blk)

= 9/25

If the fraction can be simplified, do that. 9/25 cannot be simplified.

If you need a percent for your answer, divide then multiply by 100.

A fraction bar is a division symbol.

9/25 means 9÷25.

9/25 = .36

Percent means "per hundred" To convert a decimal to a percent, multiply by 100

.36×100 is 36%

Answer:

11)  [tex]y=-(x-6)^2+4[/tex]

12)  [tex]y=(x+5)^2[/tex]

Step-by-step explanation:

Vertex form of a parabola:  

[tex]y=a(x-h)^2+k[/tex]  where (h, k) is the vertex

From inspection of the graph, the vertex is (6, 4)

[tex]\implies y=a(x-6)^2+4[/tex]

To find [tex]a[/tex], substitute the coordinates of a point on the curve into the equation.

Using point (4, 0):

[tex]\implies a(4-6)^2+4=0[/tex]

[tex]\implies a(-2)^2+4=0[/tex]

[tex]\implies 4a=-4[/tex]

[tex]\implies a=-1[/tex]

Therefore, the equation of the parabola in vertex form is:

[tex]y=-(x-6)^2+4[/tex]

From inspection of the graph, the vertex is (-5, 0)

[tex]\implies y=a(x+5)^2[/tex]

To find [tex]a[/tex], substitute the coordinates of a point on the curve into the equation.

Using point (-3, 4):

[tex]\implies a(-3+5)^2=4[/tex]

[tex]\implies a(2)^2=4[/tex]

[tex]\implies 4a=4[/tex]

[tex]\implies a=1[/tex]

Therefore, the equation of the parabola in vertex form is:

[tex]y=(x+5)^2[/tex]

We need equation of the parabolas

#1

One x intercept is present (4,0)

Now put that in vertex form of parabola

So

equation

#2

So equation

See the general quadratic equation having vertex (0,0) is shifted to (-5,0) means 5 units left .

So there is no a means a=

Answer:

36%

Step-by-step explanation:

the complement of it raining on at least one of these days = it not raining on any day

this means that if it does not rain on at least one day, it does not rain on any day

thus,

1 - probability of it not raining at all = probability it rains at least one day

probability it doesn't rain on monday = 1- 20% = 80%

probability it doesn't rain on tuesday = 1 - 20% = 80%

probability it doesn't rain on monday AND it doesn't rain on tuesday = probability it doesn't rain at all

Answer:

(-1, 3)

Step-by-step explanation:

x - 5y = -16  [Equation 1]

-x + 3y = 10 [Equation 2]

Adding both equations

Solution : (-1, 3)

Solving for x and y,

→ (x - 5y = -16) + (-x + 3y = 10)

→ x - 5y - x +3y = -16 + 10

→ -2y = -6

→ y = -6/-2

→ [ y = 3 ]

Finding the value of x,

→ x - 5y = -16

→ x - 5(3) = -16

→ x - 15 = -16

→ x = -16 + 15

→ [ x = -1]

___________________

→ -x + 3y = 10

→ -x + 3(3) = 10

→ -x + 9 = 10

→ -x = 10 - 9

→ [ x = -1 ]

Arranging them in ordered pair,

→ (x,y)

→ (-1,3)

Thus, the solution is (-1,3).

Answer: D: Passing laws for credit card companies to follow.

Step-by-step explanation:

Step-by-step explanation:

come in ! think a little bit by yourself !

when x = 1, what is f(x) ?

it is f(1) = 1² = 1

what is then g(x) ?

g(1) = 1/4 × f(1) = 1/4 × 1 = 1/4

when x = 2, what is f(x) ?

f(2) = 2² = 4

what is then g(x) ?

g(2) = 1/4 × f(2) = 1/4 × 4 = 1

and equally for x = -1 and -2.

a square function always delivers positive numbers. and so does the square function multiplied by a positive constant (like for g(x)).

the only graph, where the curve is always above the x-axis (only positive results), and where the functional value for x = 1 is much smaller than 1, and the functional value for x = 2 is actually 1, is graph D.

so, D is the right answer.

The values of the expression for x = 2, -3, 6, -5 are -10, -12, 6 and -16, respectively

The expression is given as:

f(x) = 2x - 6

When x = -2, we have:

f(-2) = 2(-2) - 6 = -10

For other values of x, we have:

f(-3) = 2(-3) - 6 = -12

f(6) = 2(6) - 6 = 6

f(-5) = 2(-5) - 6 = -16

Hence, the values of the expression for x = 2, -3, 6, -5 are -10, -12, 6 and -16, respectively
