The equation for Tree A's height t years after being planted is:

[tex]A = 34 + 2t[/tex]

The equation for Tree B's height t years after being planted is:

[tex]B = 14 + 6t[/tex]

To determine the height of both trees at the time when they have an equal height, we can set the two equations equal to each other:

[tex]A = B[/tex]

[tex]34 + 2t = 14 + 6t[/tex]

And solving for t, we find that:

[tex]t = 10[/tex]

So, 10 years after being planted,

Tree A will be 54 inches tall  [tex](34 + 2 * 10)[/tex]  and Tree B will be 74 inches tall [tex](14 + 6 * 10)[/tex].

At this point, both trees will have an equal height.

A suspension bridge: a parabola represents the profile of the cable of a suspended-deck suspension bridge.

A graph is a topic which gives us the numerical facts into visual form.

That is, a graph gives the visual representation of the data collected.

The towers supporting the cable of suspension bridge are 15m apart and 12m above the bridge it supports.

Suppose the cable hangs,following the shape of parabola,with its lowest point 20m above the bridge.

lets have the bridged centered at the origin

Three points are needed on the parabola

x = 0, y = 20

x = -7.5, y = 12

x = +7.5, y = 12

using the form ax^2 + bx + c = y, we know that c=20

x=-7.5, y = 12 and x =+7.5, y = 12; write two equations

-7.5^2a - 7.5b + 20 = 12

+7.5^2a + 7.5 + 20 = 12

use elimination

56.25a - 7.5b + 20 = 12

56.25a + 7.5b + 20 = 12

addition eliminates b

112.5a + 40 = 24

112.5=16

a = 16/112.5

a = 0.1422

Now we can write the equation

y = 0.1422x^2 + 2

About 285 numbers lie between the values 10 and 14. (option C).

A continuous probability distribution for a real-valued random variable in statistics is known as a normal distribution or a Gaussian distribution. In statistics and the natural and social sciences, normal distributions are crucial concepts.

There are 600 numbers and their mean is 10 where the standard deviation is 2.

47.5% of the numbers should fall between 10 and 14, as expected. In a normal distribution, 47.5% of the sample size will fall between the mean and two standard deviations on either side of it.

By doing calculation on option C, we got that = [tex]\frac{285}{600}*100=47.5[/tex]

A measures magnitude 8 on the Richter scale of an earthquake is 10,000 times stronger than a magnitude 4 measure on the Richter scale.

Earthquake Intensity: An earthquake is the release of energy from the movement of tectonic plates. Earthquakes can be measured on the Richter scale, which ranges from 2 to 10 and measures the magnitude of an earthquake.

Earthquake intensity is a qualitative estimate of the effects caused by an earthquake, so it has no numerical value. The Richter scale is a logarithmic scale. This means that as you move up each digit, the power increases by a factor of 10. So let's set the damage from 4 earthquakes to X. Then, 5 = 10X

=> 6 = 100X

=> 7 = 1,000X

=> 8 = 10,000X

Nata was using the partial products method to solve the multiplication problem 42 × 15. She likely wrote 20 because she was finding the product of 42 and 10, which is 420. Writing 20 was likely a shorthand for the digit 2 in 420.

In the partial product method, each digit of one number is multiplied by each digit of another number, keeping each digit in its original place. Place value is typically used to calculate the partial product. To get the product of two-digit numbers, we employ the partial product method.

The partial products method involves breaking down one factor into its place value components and multiplying each component separately, then adding the products together to get the final answer.

The Hall family utilizes sprinklers for 15 hours compared to the 35 hours used by the Nguyen family.

Let h and n represent the amount of hours each household uses its sprinkler, the Halls and the Nguyens, respectively.

They use for a total of 50 hours, thus either h + n = 50 or h = 50 - n.

Additionally, their total water output is 1050 L, thus we may use the equation below.

35h + 15n = 1050

Replace h with h = 50 - n to get

35(50 - n) + 15n = 1050

In mathematics, a square number or perfect square is an integer that is the square of an integer; in other words, we can say that a perfect square is a number that can be expressed as the product of an integer by itself or as the second power of an integer. Perfect Square Formula : Let us consider if N is a perfect square of a whole number x, then N can be represent as the product of x and x = x². So, the perfect square formula formula is , N = x². For example, If x = 3, and N = x². This means, N = 3× 3 = 3² = 9 . Here, 9 is a perfect square because it is equal to the square of a whole number, 3. We have to determine the number of perfect squares from 1 to 100.

1² = 1 ; 2² = 4 ; 3² = 9 ; 4² = 16 ; 5² = 25 ; 6² = 36 ; 7² = 49 ; 8² = 64 ; 9² = 81 ; 10² = 100
