Answer 1

Answer:

I'm not sure what the question is. I'll offer one simplification that might help.

Step-by-step explanation:

[tex]\sqrt{3} - 3(4*\sqrt{8})[/tex]

One can convert the [tex]\sqrt{8}[/tex] to [tex]\sqrt{2} *\sqrt{4}[/tex] and then that becomes [tex]\sqrt{2} *\2}[/tex]2 or 2[tex]\sqrt{2}[/tex]

[tex]\sqrt{3} - 3(4*\sqrt{2}\sqrt{4})\\[/tex]

[tex]\sqrt{3} - 3(4*2*\sqrt{2})\\[/tex] See above explanation.

[tex]\sqrt{3} - 24*\sqrt{2})\\[/tex]

A ship is stationary at sea.
A tugboat is 24km away at a bearing of 110°, and a yacht is 12km from the tugboat at a bearing of 085°.
Draw a scale diagram showing the positions of the three vessels.
Use a scale of 1 cm: 3 km.
Use your diagram to find the distance of the yacht from the ship to the nearest km.

Answers

The distance of the yacht from the ship is 35 km

How to determine the distance?

See attachment for the diagram that represents the given parameters.

The distance of the yacht from the ship is then calculated using the following law of cosine.

YS^2 = ST^2 + YT^2 - 2 * ST * YT * cos(T)

This gives

YS^2 = 24^2 + 12^2 - 2 * 24 * 12 * cos(155)

Evaluate the exponents and the products

YS^2 = 576 + 144 + 522

Evaluate the sum

YS^2 = 1242

Take the square root of both sides

YS = 35

Hence, the distance of the yacht from the ship is 35 km

probability of hitting the shaded area

Answers

The probability of hitting the shaded area is 0.64

How to determine the probability?

The diameters are given as:

D = 10

d = 6

The shaded area is calculated as:

Shaded = π((D/2)² - (d/2)²)

So, we have:

Shaded = π((10/2)² - (6/2)²)

Evaluate the exponents

Shaded = 16π

The area of the big circle is calculated as:

Area = π(D/2)²

So, we have:

Area = π(10/2)²

Evaluate the exponents

Area = 25π

The probability of hitting the shaded area is:

P = 16π/25π

Evaluate

P = 0.64

Hence, the probability of hitting the shaded area is 0.64

What is the triangle?

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

In the first diagram:

The sum of the 5k + 20 and 7k + 40 is 180

5k + 20 + 7k + 40 = 180

12k + 60 = 180

12k = 180 -60

12k = 120

k = 10

In the second diagram:

The sum of the two interior angles is equal to the exterior angle.

40 + 12k + 10 = 8k + 80

4k = 30

k = 30/4 = 15/2

Thus, in the first diagram the value of k is 10 and in the second diagram the value of k is 15/2.

Suppose s and t are directly proportional. If s=14 when t=12, what is s when t=7 ?

Answers

S/7 = 14/12

12s = 98

s = 98/12

s = 49/6

Why? Well, if this relationship is proportional, that would mean while s = 14 and t = 12, the expression in which t = 7 would have to be proportional to the first. By doing 12s = 98, we find our numerator for what s is when t = 7. Then, since t already equals 12, we have our fraction: 98/12. We can now reduce that by dividing the numerator and denominator by 2 to get 49/6. Therefore, when t = 7, s = 49/6.

Your final answer: s = 49/6.

The number of people in the sample survey is 75.

Survey sampling, as used in statistics, is the process of choosing a sample of constituents from a target population to perform a survey. The word "survey" can be used to describe a wide range of observational methods or procedures. Most frequently, a questionnaire meant to assess people's traits and/or opinions is employed in survey sampling. The topic of survey data collecting involves various methods of contacting sample participants after they have been chosen. Sampling is done to cut down on the expense and/or labor required to survey the complete target population. A census is a survey that includes all members of the target population. A sample is a subset or segment of a population from which data will be drawn.

The sample survey has

5 people in 1-4 miles per week

10 people in 5-8 miles per week

15 people in 9-12 miles per week

20 people in 13-15 miles per week

25 people in 16-19 miles per week

The number of people in the sample survey is

5 + 10 + 15 + 20 + 25

=5(1 + 2 + 3 + 4 + 5)

=5(15)

=75

Hence, the number of people in the sample survey is 75.

RXS=15
SXT=3
TXV=7
RXV=??

Answers

Answer:

Step-by-step explanation:

R × S = 15 could be 5 × 3 = 15, 3 × 5 = 15

15 × 1 = 15, 1 × 15 = 15

S ×T =3 From our previous step we can see that S could be 1 or 3 or 5 or 15.

Given that S×T =3, will make sense that S is 1 or 3

If S is 1 then T is 3 and if S is 3 then T is 1, so multiplied will give 3.

T×V=7 From previous step we see that T could be 1 or 3.

Since T×V = 7 it will make sense that T is 1, and therefore V is 7.

T ×V = 7, S ×T =3, R × S = 15, R × V = ??

1 × 7 = 7, S ×1 = 3, R × 3 = 15, 5 × 7 = ??

3 ×1 = 3, 5 × 3 = 15, 5 × 7 = 35

which statement is correct?

Answers

Answer:

The second and third equations are correct.

Step-by-step explanation:

Note that the equations are all the same, with the exception of the math operation (=,>,<,[tex]\leq[/tex], etc.). Let's do one calculation and then decide which of the statements is true.

The components may be simplified by separating the numbers from the exponents and doing the calculations separately:

(2.06x10^-2)(1.88x10^-1) becomes (2.06*1.88)*(10^-2 * 10^-1)

Left Side:

(2.06*1.88) = 3.91

(10^-2 * 10^-1) = 10^-3 [The exponents add when multiplying]

(2.06x10^-2)(1.88x10^-1) = 3.91x10^-3

Right side:

(7.69/2.3) = 3.343

(10^-2)/(10^-5) = 10^3 [The bottom exponent is subtracted from the top. ( -2 - (-5)) = 3 ]

(7.69x10^-2)/(2.3x10^-5) = 3.343x10^3

For all equations:

LEFT RIGHT

3.91x10^-3 3.343x10^3

We can now answer the question. Is the left side (3.91x10^-3 )

A. <

B. =>

C. >, or

D. =

to the right side (3.343x10^3)

We can drop the 10^-3 to make the comparison simpler, since it is the same on both sides. Think of it as dividing both sides by 10^3.

Correct?

A. 3.91 < 3.34 NO

B. 3.91 => 3.34 YES

C. 3.91 > 3.34, or YES

D. 3.91 = 3.34 NO

Answer:

Cost of a T-shirt is £4
Cost of a Hat is £1

Step-by-step explanation:

Let T be the cost of each T-shirt and H the cost of each hat

We get two equations based on the cost description

3T + 2H = 14 ...... (1)
2T + 7H = 15 ...... (2)

Multiply (1) by 2 and (2) by 3 so that the T terms are the same
(1) x 2 ==> 6T + 4H = 28 ... (3)
(2) x 3 ==> 6T + 21H = 45 ... (4)

Subtract (3) from (4) to eliminate the T terms
21H - 4H = 45 - 28 or 17H = 17 ==> H = 1

Substituting the value of H in either (1) or (2) will give us a value for T
Substitute in (1)
3T + 2*1 = 14 ==> 3T = 12, T = 4

Check
In (1) 3 *4 + 2 *1 = 14
In (2) 2*4 + 7*1 = 15

Answers

The equation of the ordered pairs (1, 4), (–1, 2), and (0, 3) is y = x + 3

How to determine the equation?

The ordered pairs are given as:

(1, 4), (–1, 2), and (0, 3)

From the above ordered pairs, we can see that the difference between the x and y values is 3.

This means that:

y - x = 3

Add 3 to both sides

y = x + 3

Hence, the equation of the ordered pairs (1, 4), (–1, 2), and (0, 3) is y = x + 3

What is the "a" value of this function?

Answers

Answer:

Step-by-step explanation:

Assuming that the 2 actually represents square, the equation is
[tex]f(x) = 12(x-2)^2 + 18[/tex]

[tex](x-2)^2 = x^2 - 4x + 4\\\\12(x-2)^2 + 18 = 12( x^2 - 4x + 4) + 18 = 12x^2 -48x + 48 + 18 = 12x^2 -48x + 66\\[/tex]

This equation is of the form
[tex]ax^2 + bx + c[/tex]

[tex]a = 12, b = -48, c = 66[/tex]

Note

Since the question is only asking for the a value which is the coefficient of x² it is clear that 12 is the coefficient without expanding (x-2)² but it is always better to proceed as above in case you are asked for b and c values also

Value of the function at x=a is [tex]12a^{2} -240a +1218[/tex].

Given function f(x)=[tex]12(x-10)^{2} +18[/tex]

We have to find the value of function at x=a.

For this we have to just put x=a in the function f(x)=[tex]12(x-10)^{2}+18[/tex]

f(a)=12[tex](a-10)^{2} +18[/tex]

we have to expand (x-10) to the power 2 to get the value of function.

f(a)=[tex]12(a^{2} +10^{2} -20a)+18[/tex]

=[tex]12a^{2}+1200-240a+18\\[/tex]

=[tex]12a^{2} -240a+1218[/tex]

Hence the value of function at x=a is [tex]12a^{2} -240a+1218[/tex] means f(a)=[tex]12a^{2} -240a+1218[/tex].
