A 5-pound bag of flour costs $12.80. What is the price per ounce?

Answer:

33. 72 cm²

Step-by-step explanation:

A= 1/2 x h x (b1+b2)

 = 1/2 x 6 x (10+14)

 = 1/2 x 6 x 24

 = 6 x 12

A= 72 cm²

The equation which results from applying the secant and tangent segment theorem to the figure is

[tex]10(a+10)=(12)^2[/tex]

The secant-tangent theorem tells the relation of the line segment made by a tangent and the secant lines with the connected circle.

According to this theorem, if the tangent and secant segments are drawn from an exterior point, then the square of this tangent segment is equal to the product of the secant segment and the line segment from that exterior point.

In the figure attached below for the circle O, the length of the DB is,

[tex]DB=10[/tex]

Here, the line segment AB is a unit. Thus, the length of line segment AD is,

[tex]AD=a+10[/tex]

The length of the tangent DE is 12 units. Thus, by the above theorem,

[tex](DE)^2=AB\times BD\\(12)^2=(a+10)\times10\\[/tex]

Hence, the equation which results from applying the secant and tangent segment theorem to the figure is

[tex]10(a+10)=(12)^2[/tex]

Answer:

see attached diagram

Step-by-step explanation:

You have three functions with restricted domains:

f(x) = 3

f(x) = 2x + 1

f(x) = -2

We used a closed point for ≤ and ≥

and an open point for < and >

As the domain of f(x) = 3 is x ≤ -3

we add a closed point at (-3, 3) and then an arrow pointing towards the increasing negative (as x is equal to or less than -3)

As the domain of f(x) = -2 is x ≥ 4

we add a closed point at (4, -2) and then an arrow pointing towards the increasing positive (as x is equal to or greater than 4)

As the domain of f(x) = 2x + 1 is restricted to -3 < x < 4

we add open points at (-3, -5) and (4, 9) and then join them with a segment

Perimeter of a rectangle is double of sum of its length  and width. The perimeter P of the considered rectangle is: Option B: [tex]P = 2x + 2y - 8[/tex]

Its the sum of length of the sides used to made the given figure.

For a rectangle, as its two sides are equal to its length and two other sides are equal to its width, thus, its perimeter is:

[tex]P = 2 \times length + 2 \times width = 2(length + width)[/tex]

For the given case, it is already given that:

The length of the considered rectangle  = x + 5 units

The width of the considered rectangle  =  y - 1 units.

Thus, we get this rectangle's perimeter as:

[tex]P = 2( x + 5 + y - 1) = 2(x + y + 4) = 2x + 2y - 8\\\\P = 2x + 2y - 8 \: \rm units[/tex]

Thus,  The perimeter P of the considered rectangle is: Option B: [tex]P = 2x + 2y - 8[/tex]

Answer:

[tex]A=\pi\times r^2[/tex]

Step-by-step explanation:

In order to find the area of a circle we multiply π by the radius, and to find the radius of a circle we have to look at the line that stops directly in the middle of the circle.

[tex]\pi\times r[/tex]

Once we then have the radius, we simply multiply the radius, (with an exponent of 2) by π and then we will have our answer. Of course, round if needed.

[tex]A=\pi\times r^2[/tex]

Answer:

[tex]a_{n}=2+3(n-1)[/tex]

Step-by-step explanation:

Step 1. To find the equation that describes the pattern, we use the arithmetic sequence formula:

[tex]a_{n}=a_{1}+d(n-1)[/tex]

Where a_n is the n'th terms and d is the common ratio between the numbers.

Step 2. The sequence we have is:

2 5 8 11

The first term is:

[tex]a_{1}=2[/tex]

And the common ratio or the difference between consecutive numbers is:

3 2+3=8 5+3=8  8+3=11

This will be the value of d:

d=3

Step 3. Substituting a_1 and d into the formula:

[tex]a_{n} =a_{1}+d(n-1)\\a_{n}=2+3(n-1)[/tex]

This is the equation that represents the number pattern, it represents that we add three each time to the previous number in the sequence.

Hence, the correct answer is [tex]a_{n}=2+3(n-1)[/tex]

=======================================================

Explanation:

Angle theta is between pi and 3pi/2. This places the angle in quadrant Q3 where both cosine and sine are negative

Use the pythagorean trig identity to get the following:

[tex]\sin^2 \theta + \cos^2 \theta = 1\\\\\sin^2 \theta + \left(-\frac{\sqrt{3}}{4}\right)^2 = 1\\\\\sin^2 \theta + \frac{3}{16} = 1\\\\\sin^2 \theta = 1 - \frac{3}{16}\\\\\sin^2 \theta = \frac{16}{16} - \frac{3}{16}\\\\\sin^2 \theta = \frac{16-3}{16}\\\\\sin^2 \theta = \frac{13}{16}\\\\\sin \theta = -\sqrt{\frac{13}{16}} \ \text{ ... sine is negative in Q3}\\\\\sin \theta = -\frac{\sqrt{13}}{\sqrt{16}}\\\\\sin \theta = -\frac{\sqrt{13}}{4}\\\\[/tex]

Angle beta is in Q1 where sine and cosine are positive.

Draw a right triangle with legs 3 and 4. The hypotenuse is 5 through the pythagorean theorem. In other words, we have a 3-4-5 right triangle.

Since [tex]\tan \beta = \frac{3}{4}[/tex], this means [tex]\sin \beta = \frac{3}{5} \ \text{ and } \ \cos \beta = \frac{4}{5}[/tex]

Use these ideas:

In this case we have: opposite = 3, adjacent = 4, hypotenuse = 5.

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

To recap:

[tex]\cos \theta = -\frac{\sqrt{3}}{4}\\\\\sin \theta = -\frac{\sqrt{13}}{4}\\\\\cos \beta = \frac{3}{5}\\\\\sin \beta = \frac{4}{5}\\\\[/tex]

They lead to this

[tex]\sin\left(\theta + \beta\right) = \sin \theta * \cos \beta - \cos \theta * \sin \beta\\\\\sin\left(\theta + \beta\right) = -\frac{\sqrt{13}}{4} * \frac{3}{5} - \left(-\frac{\sqrt{3}}{4}\right) * \frac{4}{5}\\\\\sin\left(\theta + \beta\right) = -\frac{3\sqrt{13}}{20}+\frac{4\sqrt{3}}{20}\\\\\sin\left(\theta + \beta\right) = \frac{-3\sqrt{13}+4\sqrt{3}}{20}\\\\[/tex]

The height of the all after 2 secs is 86 feet

Given the height in feet above the ground was given by the following function h(t) = -16t^2 + 75t

where:

t is the number of seconds since the ball was punted.

If the value of t = 2s, hence;

h(t) = -16t^2 + 75t

h(2) = -16(2)^2 + 75(2)

h(2) = -64 + 150
h(2) = 86

Hence the height of the all after 2 secs is 86 feet

And in an hour, the older pump can drain 1 : 7 = 1/7 of the pool

So in 1 hour, the newer pump will drain 1/3 - 1/7 = 4/21 of the pool
