What are the 3 main root functions?
The 3 main root functions are:
(2) They firmly moor the plant.
(3) They support the storage of nutrients and food.
(4) Water and minerals are delivered to the plant by the roots.
The roots of vascular plants are modified plant organs that serve as anchors for the plant and as a means of absorbing water and nutrients into the body of the plant, enabling the plant to grow higher and more quickly.
The majority of the time, roots are found below the soil's surface, but they can also be aerial or aerating, that is, they can rise above the earth or, particularly, above water.
Roots carry out the following tasks:
(1) The soil's nutrients and water are absorbed through roots.
(2) They firmly moor the plant.
(3) They support the storage of nutrients and food.
(4) Water and minerals are delivered to the plant by the roots.

What is the nature of roots of 2x² 3x 5 0?
The nature of the roots of the equation 2x^2 - 3x + 5 = 0 is imaginary or unreal.
We know that the general form of a quadratic equation is:
ax^2 + bx + c =0
The equation we have is:
2x^2 - 3x + 5 = 0
Comparing the given equation with the general form of a quadratic equation, we get that:
a = 2, b= -3, and c = 5
We know that if D = b^2 - 4ac < 0, then the roots of the quadratic equation are imaginary or unreal.
Therefore, b^2 - 4ac = (-3)^2 - 4x2x5 = -31 < 0.
Hence, we conclude that the nature of the roots of the give equation is imaginary or unreal.

The weight of an object on Mars varies directly with its weight on Earth. An object that weighs 50 pounds on Mars weighs 150 pounds on Earth. Determine a direct variation equation to represent this situation. If an object weighs 120 pounds on Earth, determine how much an object would weigh on Mars. Enter this amount, in pounds, into the space provided (enter numerical number only, not the units).
The weight of the object on Mars would be 40 pounds.
What are ratio and proportion?
A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.
An object that weighs 50 pounds on mars weighs 150 pounds on earth.
Let the object weighing 120 pounds on Earth, weighs x pounds on Mars.
We can solve this equation as :
50/150 = x/120
x = 40 pounds

Answer:
Shoes rental cost: $7
The equation to find the cost is 19 = 4x + y
Step-by-step explanation:
Each game = $4
There are 3 games
They paid a total of $19.00
We have the equation to find the cost is
19 = 4x + y
Now let's put 3 in for x to solve for the cost of renting shoes!
19 = 4(3) + y
19 = 12 + y
y = $7
So, the equation to find shoe rental cost is 19 = 4x + y, and the cost to rent shoes is $7
Answer:
Step-by-step explanation:
19=4x+y is the equation .------1

Given y1(t) = t^2 is a solution to: t^2y'' - 4ty' + 6y = 0, t > 0 find another solution using the method of reduction of order.
For a second order differential equation t²y'' - 4ty' + 6y = 0, general solution is of the form y(t) = c₁t² + c₂t³, so another solution other than y₁(t) = t² is y₂(t) = t³.
Given solution to t²y'' - 4ty' + 6y = 0 is
y₁(t) = t²
Using the method of reduction of order, let us assume, y₂(t) = v(t)y₁(t) is a solution to t²y'' - 4ty' + 6y = 0 for suitable choice of v(t). So,
y₂ = vt²
y₂' = 2vt + t²v'
y₂'' = 2v + 2tv' + 2tv' + t²v''
y₂'' = 2v + 4tv' + t²v''
Substituting this
t²×( 2v + 4tv' + t²v'') - 4t×(2vt + t²v') + 6×(vt²) = 0
t⁴v'' = 0
v'' = 0
v' = c, c is a constant
v = ct
Therefore, y₂(t) = ct×t²
y₂ (t) = ct³
Therefore general solution will be y(t) = c₁t² + c₂t³

As per the given ratio, the total number of flowers in shipment is 180.
The term Ratio in math basically compares quantities, which means that it shows the value of one quantity with respect to the other quantity.
Here we have given that the florist ordered a shipment of red, blue, and white carnations to use for table decorations at a banquet.
And we need to find the total number of carnations in the shipment.
While we looking into the given question, we know that the ratio of red : blue : white carnations in the shipment is 3:1:2.
Here we aloo know that there are 60 white carnations in the shipment
Then let us consider if a and b are two values, their ratio will be a:b,
Then the ratio of flowers is written as
=> red: blue: white = 3:1:2
Where red flowers are 3x, and the blue flowers are x, and the white flower are 2x.
So, the total number of flowers = 3x+x+2x = 6x
When we apply the value of whit\te flowers = 60
Then the value of x is calculated as,
=> 2x = 60
=> x = 30

the national average family size was reported as 3.18. a random sample of 24 families in one school district had a mean of 3.83 and a standard deviation of 1.43. at the 5% level of significance, does the average family size in this school district differ from the national average? assume the distribution is approximately normal.
As pert the t-test there is sufficient evidence that the average family size in this school district differ from the national average.
Let us assume null and alternate hypothesis.
H₀ = Average family size is 3.18
Hₐ = Average family size is not 3.18
The value of t = (Sample Mean - 3.18) / s/√n
where,
Sample Mean = 3.83
n = 24
s = 1.43
So, t = (3.83 - 3.18) / (1.43 / √24)
t = 2.2268
Degree of freedom = n - 1 = 23
The p-value = 0.0360
As the p-value <0.05, so the null hypothesis will be rejected.

2∡F+∡ADB = 180°
2∡F + 70° = 180°
∡F = 55°
∡ABD = ∡BAD = 55°
Now
∡ABD + ∡CBD = 180° (Supplementary Angles)

Sighting the position of a tree on the opposite bank of the creek and placing 4 wooden pegs at point N, O, P, and Qas shown in the figure such that MN is perpendicular to NP, NP is perpendicular to PQ, and O is the midpoint of NP. Andre claims that AMNO and AQPO are congruent.
Part A: Provide a valid argument, using geometry theorems or postulates, to validate Andre's claim that AMNO and APQO are congruent.
Part B: Which segment should Andre measure to determine the width of the creek? Explain why.
Answer:
Step-by-step explanation:
Part A: you can just restate parts of the text to make a vaild argument or you can make you own
Part B: he should measure N, O, P and Qas
Triangles MNO and QPO are congruent. To find the width of the creek, Andre should find the measurement of NP
What is congruent triangles?When two triangles are congruent, their corresponding three sides and their three angles match precisely.
Given that
O is the midpoint of NP,
NP is perpendicular to MN, and
NP is perpendicular to PQ.
When two lines intersect at a specific point, the opposite angles formed in this situation are equal.
a) Then ∠MNP =∠QPO=90°
∠MON=∠QOP
Also, NO = OP (by the definition of midpoints)
Therefore, Triangles MNO and QPO are congruent by ASA rule
And,
b) To find the width of the creek, Andre should find the measurement of NP, because according to the figure the width is represented by NP. He should find NO and OP and then add it.
