what is the square root 15v to the 4th power times square root of 2v

Answers

the square root 15v to the 4th power times square root of 2v to the 3rd power is 15v^2 x 2v^3, or 30v^5.

What is square root?

The square root of a number is a value that, when multiplied by itself, produces the original number. For example, the square root of 16 is 4 because 4 x 4 = 16. In mathematics, the square root of a number is written as a radical symbol, with the number inside the radical symbol. The square root symbol is also known as the radical symbol or radix.

To calculate this, first take the square root of 15v to the 4th power, which is 3v. Then take the square root of 2v to the 3rd power, which is 2v.

Finally, multiply 3v and 2v together to get the final answer of 30v^5.

What is the formula for finding the distance between two parallel lines?

Answers

[tex]d=\frac{|c_2-c_1|}{\sqrt{a^2+b^2}}[/tex]  is the formula used to calculate the distance between two parallel lines. This is derived from the slope-intercept equation.  

The two lines that never cross over one another are referred to as parallel lines. When the separation between these two lines is considered constant, then these two lines are parallel.

As a result, the distance between two lines can be determined by considering their perpendicular distance. The two parallel lines can be written using the slope-intercept form as y = mx + c₁ and y = mx + c₂, respectively.

Then, the formula to calculate distance is given by, [tex]d=\frac{|c_2-c_1|}{\sqrt{a^2+b^2}}[/tex]. Here, the intercepts of the two lines are c₁ and c₂, and a and b are the constants or integers.

Ellie is 1.75 meters tall. At 3 p.m., she measures the length of a tree's shadow to be 20.25 meters. She stands 16.2 meters away from the tree, so that the tip of her shadow meets the tip of the tree's shadow. Find the height of the tree to the nearest hundredth of a meter.

Answers

To find the height of the tree, we can use the tangent of the angle between the top of the tree and the tip of Ellie's shadow to find the height of the tree.

Tangent(theta) = Opposite / Adjacent

Opposite = height of tree

Adjacent = distance between Ellie and the tree

Tangent(theta) = height of tree / 16.2

We know that:

Tangent(theta) = 20.25 / 16.2

We can solve for the height of the tree by multiplying both sides of the equation by 16.2:

height of tree = Tangent(theta) * 16.2

height of tree = (20.25 / 16.2) * 16.2height of tree = 20.25

So, the height of the tree is 20.25 meters to the nearest hundredth of a meter.

Answer:  the height of the tree is 20.25 meters to the nearest hundredth of a meter.

5.2 feet
10.4 feet
12.2 feet
15.4 feet

Answers

Answer:

10.4 feet

Step-by-step explanation:

26/5 = 5.2

5.2(2)=10.4

The length of the tree's shadow is 10.4 feet. Option B is correct.

What are Similar Triangles?

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

We can use similar triangles to solve this problem.

The ratio of the height of the fence post to its shadow is the same as the ratio of the height of the tree to its shadow.

(height of fence post) / (length of fence post's shadow) = (height of tree) / (length of tree's shadow)

Substituting the given values, we get:

5 / 2 = 26 / x

where x is the length of the tree's shadow.

Cross-multiplying and solving for x, we get:

x = 26 × 2 / 5

= 10.4 feet

Therefore, the length of the tree's shadow is 10.4 feet.

Answers

Brad takes 6 minutes to run a mile assuming he can maintain the same pace.

Given that,

One lap around the inside lane of a standard track = 400m

Time taken for Brad to jog one lap around a track = 1 minute and 30 secs

We know that one mile = 1609.34 meters = 1600 meters (approximately)

Since Brad can jog 400m in 1 minute and 30 secs

1600 meters = 400*4 meters

Assuming that he can maintain the same pace:

so, the total time taken to run 1 mile = 1 minute 30 secs * 4 = 6 minutes

Hence, Brad takes 6 minutes to run a mile assuming he can maintain the same pace.

She made $33072 commission in 2011.

What is percentage?

In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.

Given,

Weekly commission of Nadia = 12%

Cost of stocks Nadia sold last week = $5300

Commission made by Nadia last week = 12% of $5300

                                                                 = (12/100) × 5300

                                                                 = 12 × 53

Commission made by Nadia last week = $636

No. of weeks in 2011 = 52 weeks

If she averages that same amount each week

Then commission made by her in 2011 = 52 × $636
