Step-by-step explanation:

The value of AB id 0.5 unit.

The Angle-Angle-Angle (AAA) criterion for the similarity of triangles states that “If in two triangles, corresponding angles are equal, then their corresponding sides are in the same ratio (or proportion) and hence the two triangles are similar”.

Any pair of angles each of which is on the same side of one of two lines cut by a transversal and on the same side of the transversal are called corresponding angles and they are always equal.

According to the given question.

A, B and C lie on the straight line segment. and A, E, and D are also lie in the straight line segment.

Also, BE = 1.75m, CD = 7m and BC = 1.5m

Now, in ΔAEB and ΔADC

EB is parallel to BC

So,

∠AEB ≅ ∠ADC   (corresponding angles)

∠ABE ≅ ∠ACD   (corresponding angles)

∠EAB ≅ ∠DAC    (common angle to the both triangle)

Hence, by AAA Similarity rule

ΔAEB is similar to ΔADC

Therefore,

[tex]\frac{AE}{AD} =\frac{BE}{CD} =\frac{AB}{AC}[/tex]         (sides of the similar triangles are in proportion)

So,

[tex]\frac{BE}{CD} =\frac{AB}{AC} \\\implies \frac{AB}{AC} =\frac{1.75}{7} ....(i)[/tex]

Now, AC = AB + BC   (as, A, B, and C lie on a straight line)

[tex]\implies \frac{AB}{AB+BC} =\frac{1.75}{7}[/tex]       (from (i))

[tex]\implies \frac{AB}{AB+1.5} =\frac{1.75}{7}[/tex]

[tex]\implies 7AB = 1.75AB + 1.75(1.5)[/tex]

[tex]\implies 7AB -1.75AB = 2.625[/tex]

[tex]\implies 5.25AB = 2.625[/tex]

[tex]\implies AB = \frac{2.625}{5.25} = 0.5[/tex]

Hence, the value of AB id 0.5 unit.

Answer:

Step-by-step explanation:

Remark

Since this is a multiple choice question, you need not worry excessively about solving the equation that sin(4x) and Cos(3x + 13) produce. It can be done, but you will spend a lot time and drink a lot of coffee doing it.

C

The wording of this problem is not the best. 13 is not in any way considered.

Not only are the two angles equal (52) but they add to 104 which is greater than 90.

11 is the next one you should look at

4*11 = 44

3*11 + 13 = 46

That gives you the right answer, but the question you have to ask yourself is are you answering the question? I don't think you are. The question is the number of degrees in the smaller angle. I think that means that you have already substituted a value for x.

I think the answer is C.

Answer:

x2- 2x+1 =x2-x-x+1

=x(x-1) -1(x-1)

=(x-1)(x-1)

The number of cups will be equal to 496.

The sequence in which every next number is the addition of the constant quantity in the series is termed as the arithmatic progression

Here we have the data:-

The bottom row has 61 cups

If there are 16 total rows

The number of the cups will be calculated as:-

[tex]S_n=\dfrac{n(a_1+a_n)}{2}[/tex]

Here a1 is first term 1

an is last term 2

n is the total number of the rows

By putting the values in the question we will get:-

[tex]S_n=\dfrac{16(1+61)}{2}=\dfrac{16\times 62}{2}=496\ cups[/tex]

Hence the number of cups will be equal to 496.

Answer: 8y

Step-by-step explanation:

The values needed to find the length AB will be;

⇒ AB = √(3x)² + (- 8y)²

Line segment is a part of the line which have two endpoints and bounded by two distinct end points and contain every point on the line which is between its endpoint.

Given that;

The coordinate are,

⇒ A = (- 5x, 4y)

⇒ B = (- 2x, - 4y)

Now,

Since, We know that;

The distance between the points (x₁ , y₁) and (x₂, y₂) is,

⇒ d = √ (x₂ - x₁)² + (y₂ - y₁)²

So, The distance between the points (- 5x, 4y) and (- 2x, - 4y) is,

⇒ d = √ (- 2x - (- 5x))² + (- 4y - 4y)²

⇒ d = √(3x)² + (- 8y)²

Thus, The values needed to find the length AB is find as;

⇒ AB = √(3x)² + (- 8y)²

Step-by-step explanation:

To find extreme values, take the first derivative

[tex]y = - 3 {x}^{2} + 16x - 16[/tex]

Solve the equation for x.

[tex]x = \frac{ - 16 + \sqrt{256 - 192} }{ - 6} [/tex]

or

[tex]x = \frac{ - 16 - \sqrt{256 - 192} }{ - 6} [/tex]

[tex]x = \frac{ - 16 + \sqrt{64} }{ - 6} [/tex]

or

[tex]x = \frac{ - 16 - \sqrt{64} }{ - 6} [/tex]

We then get

[tex]x = \frac{4}{3} [/tex]

or

[tex]x = 4[/tex]

So our extreme values occur at x=4/3 and x=4

Zeroes:

[tex] - {x}^{3} + 8 {x}^{2} - 16x[/tex]

[tex] - x( {x}^{2} - 8x + 16)[/tex]

[tex] - x(x - 4) {}^{2} [/tex]

[tex] - x = 0[/tex]

[tex](x - 4) {}^{2} = 0[/tex]

[tex]x = 4[/tex]

So we have a double root at 4, and a root of 0. We have two positive roots and one non negative root

End behavior:

Since we have a negative leading coefficient and a odd degree, as x becomes more positive, y will become negative and as x becomes more negative, y will become positive.

Answer:

0.035 grams

Step-by-step explanation:

Grams of salt per gram of ocean water

For every gram of ocean water, there is 0.035 grams of salt dissolved in it.

The salinity of earths oceans,

→ a = 525 g

Amount of water for the salinity,

→ b = 15 kg

→ b = 15 × 1000

→ [ b = 15000 g ]

Then find the grams of salt for every gram of ocean water,

→ a ÷ b

→ 525 ÷ 15000

→ 0.035 g

Hence, answer is 0.035 grams of salt.

Answer:

0.98 $/cup

Step-by-step explanation:

The final answer asks for price/cup, as "per" means "divided by".

So, our final units will be in $/cup.

We are given that for every 2 gallons, it will cost $31.36.

In order to get from gallons to cups, we need to convert units.

In 1 gallon, there are 16 cups.

So, our conversion factor will be 16 cups/1 gallon.

[tex]\frac{31.36}{2} *\frac{1}{16} \\\\= 0.98[/tex]$/cup

Important things to note:

- With these types of problems, it makes it much easier if you just figure out what units you need in the final answer, and then use conversions and dimensional analysis to get the answer

The cost of the small package because...

Step-by-step explanation:

Cost of 1 postcards = $0.25

Cost of 4 postcards = 0.25 x 4 = 1

Cost of 1 letter = $0.44

Cost of 5 letters = 0.44 x 5 = 2.2

Cost of 1 large envelope = $0.80

Cost of 2 large envelopes = 0.80 x 2 - 1.6

Cost of 1 small package =$5.10

Since the cost of small package is highest

So, It will increase the mean

So,  the cost of the small package will skew the mean

The inequality compares the left (l), right (r), and trapezoidal (t) sum approximations of the area under the curve is C. r < t < l.

From the information given, it should be noted that f'(x) is negative. Therefore, L > R. Also since f"(x) is negative, T > R.

f(x) = 2 cos 2x.

f'(x) = -4 sin 2x

f"(x) = -8 cos 2x

Therefore, the inequality compares the left (l), right (r), and trapezoidal (t) sum approximations of the area under the curve is r < t < l
