Answer:

It is the diameter of the circle

it is 7 cm

it is a chord

Explanation:

First, we notice that the line segment CB passes through the centre of the circle and its endpoints touch the circumference - this tells us that CB is the diameter.

Furthermore, any line segment whose endpoints lie on the circumference of the circle is a chord (meaning that the diameter is the longest chord), and so we deduce that CB is also a chord.

Since CB is the diamter, its length is 2 times the radius. The raduis of the circle we know is DA = 3.5 cm; therefore, the dimater is CB = 2 DA = 2 * 3.5 = 7 cm.

Hence, the correct choices are:

It is the diameter of the circle

it is 7 cm

it is a chord

The slope of the line that passes through points (x1, y1) and (x2, y2) is computed as follows:

Replacing with the points (-8, 3) and (0,1) we get:

The 30-60-90 triangle is given by

AS we can note , the hypotenuse is twice as long as the shorter leg. Additionally, the longer leg is square root of 3 tines as long as the shorter leg. Therefore, the answer is option C and F

The expression given is,

Subtract 3 from both sides

Divide both sides by 5

Apply absolute rule:

Add 3 to both sides

Therefore, the answer has the form:

Hence, the solution using interval notation is

Lines are parallel and on the same plane. The final answer, "No, because the lines are in the same plane," is the proper response.

64 ounces of cherries are displayed in all in the farm stand.

According to the question,

We have the following information:

Farm stand has cherries on 2 shelves.

Number of boxes in each shelf = 4 boxes

So, the number of boxes in 2 shelves will be (2*4) or 8.

Ounces of cherries in each box = 8 ounces

Now, the ounces of cherries in 8 boxes can be easily found by multiplying the ounces of cherries in 1 box by the number of total boxes.

Ounces of cherries in 8 boxes = (8*8) ounces

Ounces of cherries in 8 boxes = 64 ounces

Now, the expression that represents the amount is (number of shelves*number of boxes*ounces of cherries in each box).

Hence, the ounces of cherries displayed in all is 64 ounces.

Exponents

Exponent is defined as the method of expressing large numbers in terms of powers. That means, exponent refers to how many times a number multiplied by itself.

For example:-

[tex]5^4[/tex] can be written as 5*5*5*5.

Here 4 is the exponent or power and 5 is the base.

There are some laws of exponents which we use while calculating the answer to such expressions.

Given expression:-

[tex]\frac{12^7*30^5}{25^2*8^5*27^4}[/tex]

We have to simplify the given solution using the laws of exponents.

First we will divide them in their prime factors.

We know that,

The velocity is v= 30.6 ft/ sec.

Velocity defines the direction of the movement of the body or the object. Speed is primarily a scalar quantity. Velocity is essentially a vector quantity. It is the rate of change of distance. It is the rate of change of displacement.

Given that,

We have given the height

Answer:

The distance from the edge of the fountain to the centre is approximately 23.87 inches.

The water fountain forms a circle. The distance around the water fountain is the circumference of the circle formed.

Therefore,

circumference = 2πr

150 = 2πr

The distance from the edge of the fountain to the centre is the radius of the circle formed. Therefore,

75 = πr

r = 75 / 3.14159

r = 23.8732616287

r = 23.87 inches

The distance from the edge of the fountain to the centre is approximately 23.87 inches.

The single trig function that simplifies the function is sec(t)

Trigonometry deals with the functions of angles and how they're applied.

Given cot(t)/csc(t)-sin(t)

since csc(t) =  1/sin(t) , we have:

[tex]\frac{ cot(t)}{csc(t)-sin(t)} = \frac{cot(t)}{\frac{1}{sin(t)} - sin(t) }[/tex]

[tex]\frac{ cot(t)}{csc(t)-sin(t)} = \frac{cot(t)}{\frac{1-sin^{2}(t) }{sin(t)} }[/tex]

since:

cos²(t) = 1 - sin²(t)

Therefore we have:

cot(t) / csc(t)-sin(t) = cot(t)/ cos²(t)/sin(t)

cot(t) / csc(t)-sin(t) = cot(t) / cos(t).cos(t)/sin(t)

Since  cos(t) / sin(t) = 1/tan(t) = cot(t)

Therefore:

cot(t) / csc(t)-sin(t) = cot(t)/ cot(t)×cos(t)

cot(t) / csc(t)-sin(t) = 1/cos(t)

Since   1/cost = sec(t)

Finally, cot(t) / csc(t)-sin(t) is sec(t).

Let's use the variable x to represent the amount of pure acid and y to represent the amount of 10% acid.

Since the total amount wanted is 90 L, we can write the equation:

Also, the final solution is 81%, so we can write our second equation:

From the first equation, we can solve for y and we will have y = 90 - x.

Using this value in the second equation, we have:

Solving for x, we have:

Therefore the amount of pure acid to be used is 71 L and the amount of 10% acid is 19 L.
