Answer:

The distance between points T and U is 12 units.

Step-by-step explanation:

Let [tex]T(x,y) = (5,-6)[/tex] and [tex]U = (-7,-6)[/tex]. The distance between points T and U represents a straight line, whose is length ([tex]TU[/tex]) can be determined by Pythagorean Theorem. That is:

[tex]TU = \sqrt{(x_{U}-x_{T})^{2}+(y_{U}-y_{T})^{2}}[/tex] (1)

If we know that [tex]x_{T} = 5[/tex], [tex]x_{U} = -7[/tex], [tex]y_{T} = -6[/tex] and [tex]y_{U} = -6[/tex], then the length between those coordinates is:

[tex]TU = \sqrt{(-7-5)^{2}+[-6-(-6)]^{2}}[/tex]

[tex]TU = 12[/tex]

The distance between points T and U is 12 units.

Answer:

The required answer is 100 .

Step-by-step explanation:

Given function to us is ,

⇒ f(n) = 4n + 2 . And we need to find (f • f) (-3)

So , first let's find f•f , which will be ,

⇒ (f • f) = (4n + 2)(4n + 2)

⇒ (f • f) = 4n ( 4n + 2 ) +2 ( 4n + 2)

⇒ (f • f) = 16n² + 8n + 8n + 4

⇒ (f • f) = 16n² + 16n + 4

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

Now we need to find (f • f)(-3) . So on substituting f = (-3) , we have :-

⇒ (f • f)(n) = 16n² + 16n + 4

⇒ (f • f)(-3) = 16*(-3)² + 16*(-3) + 4

⇒ (f • f) (-3) = 16* 9 - 48 + 4

⇒ (f • f)(-3) = 144 - 44

⇒ ( f • f) (-3) = 100

Answer/Explanation:

When you change the slope, it will affect the steepness of the graph/line.

When you change the y-intercept (b) it will affect where the graph crosses the y axis.

-increasing the y-intercept will make the graph move up and

decreasing will make the y-intercept go down.

Answer:

2/5

Step-by-step explanation:

Average is the ratio of the sum of the data to the sample size

Sum of data = 2/5-4/5+9/5/+1/5

Sum of data = (2-4+9+1)/5

Sum of data = 8/5

Sample size = 4

Average = 8/5÷4

Average = 8/5× 1/4

Average = 2/5

Hence the average monthly change in water level is 2/5

Answer: See explanation

Step-by-step explanation:

The dimensions of the first drawing will be 1/3 the dimensions of the leaf and the dimension of the oak leaf is 5 1/2 inches. Therefore, the dimensions of the 1st leaf:

= 1/3 × 5 1/2

= 1/3 × 11/2

= 11/6

= 1 5/6 inches

This is less than 5 1/2 inches

The dimensions of the second drawing will be 2 1/2 the dimensions of the leaf. This will be:

= 2 1/2 × 5 1/2

= 5/2 × 11/2

= 55/4

= 13 3/4 inches

Thus is greater than 5 1/2 inches

Answer: This means that the population increased a 20% between the year 2000 and the year 2010.

Step-by-step explanation:

In this case, we have that 25,000 is the 100%.

Now we want to know which percentage represents 30,000

Let's suppose that the percentage is X.

Then we can have a system of equations:

30,000 = X

25,000 = 100%

To find the value of X, we can take the quotient of these two equations:

30,000/25,000 = X/100%

(30,00/25,000)*100% = X = 120%

Then in the 2000 we had a 100%, and in the 2010 there was a 120%.

The difference is:

120% - 100% = 20%

This means that the population increased a 20% between the year 2000 and the year 2010.

Answer:

pretty sure the tree's 20 feet

According to proportion if a tree casts a shadow of 40 feet it;s height is 20 feet.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

We know 1 yard is 3 feet.

Given, The shadow of the tree is 40 feet long. A yardstick placed next to the tree casts a 6-foot shadow and assuming the height of the tree to be x.

∴ x : 40 : : 3 : 6.

x/40 = 3/6.

6x = 120.

x = 20 feet.

Answer:

No

Step-by-step explanation:

When working with negative numbers in terms of depth, greater depth are depicted by values as we move farther to the left of the number line.

With this in mind, - 75 feets is farther to the left of the number line and as such represents a greater depth value Than - 68 feets

Therefore, when expressing depth or elevation distances, the values should be iewwd in absolute terms. Then |75| > |68|. While bearing in mind that depth is downward and thus negative

Answer:

a) The maximum height that the ball reaches is 4 meters.

b) The height of the ball when it is released from thrower's hand is 2 meters.

c) The ball will take approximately 0.966 seconds to hit the surface of Jupiter.

Step-by-step explanation:

a) Let [tex]h(t) = -12.5\cdot (t-0.4)^{2}+4[/tex], where [tex]t[/tex] and [tex]h(t)[/tex] are the time and height, measured in seconds and meters. Since this equation is in vertex form, the maximum height corresponds to the value associated with the dependent variable (height). That is:

[tex]h(t) -4 = -12.5\cdot (t-0.4)^{2}[/tex]

Hence, the maximum height that the ball reaches is 4 meters.

b) The height of the ball when the ball is released from thrower's hand is the height of the ball at [tex]t = 0\,s[/tex]. Then, we evaluate the function:

[tex]h(0) = -12.5\cdot (0-0.4)^{2}+4[/tex]

[tex]h(0) = 2\,m[/tex]

The height of the ball when it is released from thrower's hand is 2 meters.

c) The instants when the ball hits the ground are those instants [tex]t[/tex] so that [tex]h(t) = 0[/tex]. Then:

[tex]-12.5\cdot (t-0.4)^{2}+4 = 0[/tex]

[tex]-12.5\cdot (t^{2}-0.8\cdot t +0.16)+4 = 0[/tex]

[tex]-12.5\cdot t^{2}+10\cdot t +2 = 0[/tex]

By the Quadratic Formula we obtain the following roots:

[tex]t_{1} \approx 0.966\,s[/tex], [tex]t_{2}\approx -0.166\,s[/tex]

Only the first root is physically reasonable, since time is a positive real variable.

The ball will take approximately 0.966 seconds to hit the surface of Jupiter.
