The maximum distance d in kilometers that you can see from a height of h meters is given by d=3.2/h. Findhow far you can see from the top of the building, a height of 290.7 meters. Round to the nearest tenth of akilometer.

Answers

Answer 1

Explanation

We are told that the maximum distance, d in kilometres that can be observed is given by

[tex]d=\frac{3}{2}h[/tex]

If the height of the building is 290.7 meters, then

The value of d will be calculated as

[tex]\begin{gathered} d=\frac{3}{2}\times h=\frac{3}{2}\times290.7 \\ \\ d=436.05\text{ Km} \end{gathered}[/tex]

Thus, the value of d will be 436.1 km

math question #12solve for the missing value x 1/2: 4 = 1/3 : x

Answers

To find the value of x we need to write the equation in another form that tells us what to do; both sides of the equations are ratios then we have:

[tex]\begin{gathered} \frac{1}{2}:4=\frac{\frac{1}{2}}{4} \\ \text{ and} \\ \frac{1}{3}:x=\frac{\frac{1}{3}}{x} \end{gathered}[/tex]

Then the equation is:

[tex]\frac{\frac{1}{2}}{4}=\frac{\frac{1}{3}}{x}[/tex]

Solving for x we have:

[tex]\begin{gathered} \frac{\frac{1}{2}}{4}=\frac{\frac{1}{3}}{x} \\ \frac{1}{8}=\frac{1}{3x} \\ 3x=8 \\ x=\frac{8}{3} \end{gathered}[/tex]

() Organic sugar used to be sold at a bulk price of $3.70 per pound. The price was recently increased by 20%. What is the current price per pound?

Answers

It is given that an item used to be sold for $3.70 per pound.

It is required to find the current price per pound if the price was increased by 20%.

A 20% increase in the price, $3.70 is calculated as:

[tex]\frac{100+20}{100}\cdot3.70=\frac{120}{100}\cdot3.70=4.44[/tex]

Hence, the current price of the item is $4.44 per pound.

The current price of the item is $4.44 per pound.

In developing her science project, Leigh learned that light travels at a constant rateand that it takes 500 seconds for light to travel the 93 million miles from the Sun toEarth. Mars is 142 million miles from the Sun. About how many seconds will it takefor light to travel from the Sun to Mars?A. 235 secondsB. 327 secondsC. 642 secondsD. 763 seconds

Answers

D. 763 seconds

Explanation:

Data:

Seconds light travels distance between Sun and Earth : 500 seconds

Distance between Sun and Earth: 93 million miles

Distance between Sun and Mars: 142 million miles

Formula: (see image below)

Solution:

From Sun to Mars the light takes (142 * 500) / 93 = 763 seconds

NB:

The tactic is to first put the data given in a table like in the image above, to first multiply diagonally then divide horizontally. (starting from the data that his paired data).

Here the paired data missing is the time it takes for the light to travel from the Sun to Mars, therefore you'll multiply the distance between the Sun to Mars (known data missing a pair) by the time it takes light to travel from the Sun to Earth (known data with its pair), then divide the result by the distance between the Sun and earth (pair of the former mentioned known data)

MATRECIES: Suppose ={u,v,w}⊆R3 is linearly independent. Determine if the set 4 ={u, v, v−w, u+v+w} is linearly independent or linearly dependent.

Answers

The set is linearly dependent.

To explicitly prove this, we need to show there is at least one choice of constants [tex]c_1,c_2,c_3,c_3\in\Bbb R[/tex] such that

[tex]c_1 u + c_2 v + c_3(v-w) + c_4(u+v+w) = 0[/tex]

or equivalently,

[tex](c_1 + c_4) u + (c_2 + c_3 + c_4) v + (-c_3 + c_4) w = 0[/tex]

which is the same as solving the system of equations

[tex]\begin{cases} c_1 + c_4 = 0 \\ c_2 + c_3 + c_4 = 0 \\ -c_3 + c_4 = 0 \end{cases}[/tex]

From the first and last equations, we have [tex]c_1=-c_4[/tex] and [tex]c_3=c_4[/tex]. Substituting these into the second equation leaves us with [tex]c_2-2c_1=0[/tex], and so the overall solution set is

[tex]c_1 = \dfrac12 c_2 = -c_3 = -c_4[/tex]

for which there are infinitely many not-all-zero solutions.

What is probability ?

Probability is a branch of mathematics that deals with calculating the probability of a given event, expressed as a number between 1 and 0. An event with a probability of 1 can be considered certain: for example, the probability of a coin toss. a toss that results in either "heads" or "tails" is 1 because there are no other options, assuming the coin lands flat. An event with  probability 0.5 can be considered equally likely to occur or not to occur: for example, the probability that a coin toss results in heads is 0.5, because the toss is equally  likely to result in tails." An event with  probability  0 can be considered impossible: for example, the probability that the a coin lands (uniformly) without both sides up is 0, because either "heads" or "tails" must be  up.

The image of the point P(x, y) = (4, 2) by means of a translation formula is point P'(x, y) = (- 1, 4).

What is the image of a given point after making a translation?

In this question we find the coordinates of a point set on Cartesian plane which is modified by using a translation, a kind of rigid transformation. Rigid transformations are transformations applied on geometric loci such that Euclidean distances are conserved.

Vectorially speaking, translations are described by the following formula:

P'(x, y) = P(x, y) + T(x, y)

Where:

P(x, y) - Original pointP'(x, y) - Resulting pointT(x, y) - Translation vector

If we know that P(x, y) = (- 9, - 3) and P'(x, y) = (- 14, - 1), then the translation vector is:

T(x, y) = P'(x, y) - P(x, y)

T(x, y) = (- 14, - 1) - (- 9, - 3)

T(x, y) = (- 5, 2)

Then, the image of the point (4, 2) is:

P'(x, y) = (4, 2) + (- 5, 2)

P'(x, y) = (- 1, 4)

The image of the point (4, 2) by using a translation formula is (- 1, 4).

Hello! Need some help on parts a,b, &c. The question and rubric is linked below. Thank you!

Answers

Answer:

Part A: -5/9, 6/10, -7/11, 8/12

Part B:

[tex]f(n)=(-1)^{n}(\frac{n}{n+4})[/tex]

Part C: Positive

Explanation:

The given sequence is:

[tex]-\frac{1}{5},\frac{2}{6},-\frac{3}{7},\frac{4}{8},....[/tex]

As seen above the sequence is an alternating sequence because it changes in sign

Also, neglecting the sign chnages, we will observe, a common diffference of 1 in the numerator and denominator

a) Therefore, if the pattern continues, the next 4 terms in the sequence are:

-5/9, 6/10, -7/11, 8/12

b)

Without the sign, the explicit equation representing the numerator is calculated below:

1, 2, 3, 4......

The first term, a = 1

The common difference, d = 1

This is an arithmetic sequence

N(n) = a + (n - 1)d

N(n) = 1 + (n - 1)(1)

N(n) = 1 + n - 1

N(n) = n

The explicit equation representing the denominator is calculated below

5, 6, 7, 8........

The first term, a = 5

The common difference, d = 1

D(n) = a + (n - 1)d

D(n) = 5 + (n - 1)(1)

D(n) = 5 + n - 1

D(n) = n + 4

The alternating sequence will include the term below:

[tex](-1)^n[/tex]

Therefore, the explicit equation for f(n) representing the sequence is:

[tex]f(n)=(-1)^n(\frac{n}{n+4})[/tex]

Part C) The sign of f(56) will be:

(-1)^56 = 1

Since this gives us a positive value, the sign of f(56) is positive

E.
Answer: $5 or less

Answers

The inequality that represents the equation is 8x+4<=28. The money spent on each cup is $3 or less. So, B and D are the correct options

Number of cups ordered by Kara = 8 cups

Money spent on the child's meal by Kara = $4

Total money with Kara = $28

Let x represent the money Kara will spend on each cup of soup

In formulation of the equation we get the following:

Number of cups*Money she can spend on each cup + Money spent on child's meal <= 28

8x + 4<=28

Solving the inequality:

8x<=24

x<= $3

So, the cost of a cup is $3 or less

Solution:

Given:

Recall that the z-value is expressed as

A) maximum score that can be in the bottom 10% of scores

using the table of z-values,

for the bottom 10% scores, we have

[tex]z=-1.28155156554[/tex]

To evaluate x, substitute the value of z into equation 1.

Thus,

[tex]\begin{gathered} -1.28155156554=\frac{x-3.7}{0.91}\text{ } \\ \Rightarrow x=2.5337895 \end{gathered}[/tex]

Thus, the maximum score that can be in the bottom 10% of scores is 2.5

B) Two values for which the middle 80% of scores lie.

From the z score values shown below:

The z scores of the value are

[tex]\begin{gathered} z_1=-1.28 \\ z_2=1.28 \end{gathered}[/tex]

Thus,

[tex]\begin{gathered} \text{when z=-1.28, we have} \\ -1.28=\frac{x-3.7}{0.91}\text{ } \\ \Rightarrow x=2.5352 \\ \text{when z=1.28, we have} \\ 1.28=\frac{x-3.7}{0.91} \\ \Rightarrow x=4.8648 \end{gathered}[/tex]

Thus, the two values for which the middle 80% of scores lie are 2.5 and 4.86.
