Answer:

D. The clinic opened at 7:30 A.M. and closed at 6:30 P.M.

Step-by-step explanation:

Pay attention to the times, and the amount of time the given location is open.

Only option D makes sense since the clinic open for 11 hours and the difference from the times given is exactly 11 hours; the other options are off, some give longer, and some give fewer amount of time.

Answer:

The clinic opened at 7:30AM and closed at 6:30PM

Step-by-step explanation:

The gragh shows The clinic opean 11 hours.

So It  7:30+11h= 18:30=6:30PM

SO This one is correct

Answer:

4) add the equations to eliminate x

Step-by-step explanation:

After adding the equations then you can use the value you found for y to substitute back into one of the equations in order to find x

Answer:

cot theta = -√3

Step-by-step explanation:

we are given that  cos theta = - √3/2 within the range 180° < theta < 270° and

since cos theta = adj/hyp

adj = - √3

hyp = 2

Get the opposite using the pythagoras theorem

hyp^2 = opp^2 + adj^2

2² = opp² + (-√3)²

4 = opp² + 3

opp² = 4-3

opp² = 1

opp = 1

tan theta = opp/adj

tan theta = - 1/√3

Recall that cot theta = 1/tan theta

cot theta = 1/(-1/√3)

cot theta = -√3

Answer:

The equation is [tex]x^{2} +2\cdot x + 2 = 0[/tex]-

Step-by-step explanation:

According to the statement, we have a second order polynomial of the form [tex]A\cdot x^{2}+ B\cdot x + C = 0[/tex], whose solutions can be found by Quadratic Formula:

[tex]x_{1,2} = \frac{-B\pm \sqrt{B^{2}-4\cdot A\cdot C}}{2\cdot A}[/tex] (1)

Where [tex]A[/tex], [tex]B[/tex] and [tex]C[/tex] are the coefficients of the polynomial.

If roots are conjugated complex numbers, then:

[tex]B^{2}-4\cdot A\cdot C < 0[/tex] (2)

[tex]B^{2} < 4\cdot A \cdot C[/tex]

If we know that [tex]A = 1[/tex], [tex]C = 2[/tex] and [tex]x_{1,2} = -1\pm i[/tex], then we find that:

[tex]-1\pm i = -\frac{B}{2}\pm \frac{\sqrt{B^{2}-8}}{2}[/tex]

[tex]-2 \pm i\,2 = -B \pm \sqrt{B^{2}-8}[/tex]

By comparing each side, we have the following system of equations:

[tex]-B = -2[/tex] (3)

[tex]\sqrt{B^{2}-8} = 2[/tex] (4)

Whose solution is [tex]B = 2[/tex].

In a nutshell, the equation is [tex]x^{2} +2\cdot x + 2 = 0[/tex]-

Answer:

Is there supposed to be a picture???

Step-by-step explanation:

Answer:

I think it's A, if you just subtract 25 from each top # you should get the right one

edit; yah it's A

Answer:

B is the correct answer

Step-by-step explanation:

Look at the graph. For every day, there should be 25 less containers of peanuts than popcorns. Let X represent popcorns. Everyday, X - 25 should be your amount of peanut containers.

Only A and B works, so now just add the total amount of containers for both peanuts and popcorns.

225 + 200 + 150 + 300 + 200 + 175 + 125 + 275 = 1650

Only B matches the description of 1650 total containers. So, B is your answer.

Answer:

2.8a²+0.9a - 1.2

Step-by-step explanation:

Given the expression 0.3(3a-4)-0.05(8a)(-7a)

Expand using the distributive law

0.3(3a-4)-0.05(8a)(-7a)

0.3(3a)-0.3(4)-0.05(8a)(-7a)

0.9a-1.2 - 0.05(8a)(-7a)

0.9a - 1.2 + 2.8a²

Rearrange

2.8a²+0.9a - 1.2

Hence the required expression is 2.8a²+0.9a - 1.2

Step-by-step explanation:

edg 21 ^u^

The graph x² + ( y²/49 )>1 is correct. The correct option is A.

Inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.

The given inequality is x² + ( y²/49 )>1;. The graph is plotted on the x-y plane. The curves of the graph cut the y-axis at positive 7 and negative 7 and cut the x-axis at positive 1 and negative 1.

Hence, the correct option is A.

Step-by-step explanation:

y = -9x - 1

You need a value that will make y = 0

-9x - 1 = 0             Add 1 to both sides

-9x = 1                   Divide by - 9

x = 1/-9

D. 16√3

Step-by-step explanation:

To find the area, you have to find the height. To find that, you spit the triangle in half for a 30 - 60 - 90 triangle and figure out that the height is 4√3.

After you find the height, you do the equation for the area of a triangle which is 1/2 side * height, and you fill it out.

1/2 8 * 4√3

4 * 4√3

16√3

Answer:

19.1 miles

Step-by-step explanation:

The situation given represents a right triangle.

Thus, we would use trigonometric function to find how far north the boat travelled.

Let's represent how far the boat travelled north with "x".

Thus:

Reference angle = 23°

Opposite = x

Adjacent = 45 miles

Apply TOA:

Tan 23° = Opp/Adj

Tan 23° = x/45

Multiply both sides by 45

45 × Tan 23° = x

x = 45 × Tan 23°

x = 19.1013667

x = 19.1 miles (nearest tenth of a mile)

Answer:

15%

Step-by-step explanation:

not that hard just make it a decimal then at the point go back twice and there its 15%

Answer:

15%

Step-by-step explanation:

Since 100 isn't the denominator we need to make it a denominator.

3/20 x 1/5 = 3/100 we need to do the same to the denominator because whatever we do to the denominator has to do with the numerator 3 x 5 = 15,

15/100 means 15%!

Answer:

6

Step-by-step explanation:

Recall the area of a triangle formula

[tex]A=\frac{bh}{2}[/tex] where b = base and h = height

The triangle shown has a height of 4cm and a base length 3cm

Using this information we plug in the values into the formula

[tex]A=\frac{4*3}{2} \\4*3=12\\\frac{12}{2} =6[/tex]

Hence, the area of the triangle is 6 square centimeters

Answer:

Ok so the area of the triangle is 6

Step-by-step explanation:

a= 1/2 bh

a= 1/2 * 3 * 4

a= 1/2 * 12

a= 6
