an old friend tells you that 30 years ago she nailed a sign into a tree trunk at a height of 1 meter. she now says the sign is 25 meters up in the tree. should you believe her? why or why not?
You should not believe her .
Given that,
You learn from an old friend that thirty years ago, she nailed a sign into the trunk of a tree at a height of one meter. She now claims that the sign is located 25 meters up a tree.
Meristems that are found at the tips of branches allow trees to grow taller. Apical meristems are the name for these meristems. Due to apical meristems, roots also spread into the soil by developing at their terminals. Apical meristems can be seen in every tree bud you can see. Another meristem, the vascular cambium, which was previously noted, is responsible for the expansion of trunk diameter. The trunk, branches, and roots continue to get bigger because the vascular cambium creates new xylem and phloem every year. Have you ever witnessed a fence board or wire transform into a tree?
The vascular cambium is responsible for that outcome. Height development prevents the fence wire or board from rising into the air.
Therefore, you should not believe her .

a grasshopper jumps off of a tree stump. the height, in feet, of the grasshopper above the ground after t seconds is modeled by the function shown. h(t)= -t^2 + 4/3t + 1/4
After how many seconds will the grasshopper land on the ground?
The function h(t)= -t^2 + 4/3t + 1/4 is a quadratic function
The grasshopper lands on the ground after 1.5 seconds
How to determine when the grasshopper lands on the ground?The function is given as:
h(t)= -t^2 + 4/3t + 1/4
When the grasshopper lands on the ground, h(t) = 0.
So, we have:
-t^2 + 4/3t + 1/4 = 0
Multiply through by -12
12t^2 - 16t - 3 = 0
Expand
12t^2 + 2t - 18t - 3 = 0
Factorize
2t(6t + 1) - 3(6t + 1) = 0
Factor out 6t + 1
(2t- 3)(6t + 1) = 0
Split
2t- 3 = 0 or 6t + 1 = 0
Solve for t
t = 1.5 or t = -1/6
Time cannot be negative.
So:
t = 1.5
Hence, the grasshopper lands on the ground after 1.5 seconds

Using Green's Theorem, find the outward flux of F across the closed curve C. \[ F=\sin (6 y) i+\cos (4 x) j \] \( \mathrm{C} \) is the rectangle with vertices at \( (0,0),\left(\frac{\pi}{6}, 0\right)
the outward flux of F across the closed curve C is -5π/32 + √2π/72.
To find the outward flux of the vector field F = sin(6y)i + cos(4x)j across the closed curve C, we can apply Green's Theorem.
Green's Theorem states that for a vector field F = P(x, y)i + Q(x, y)j and a simple closed curve C with positively oriented boundary, the outward flux across C is given by the line integral of F along the curve C:
Flux = ∮C F · dr = ∬R (Qx - Py) dA,
where R is the region enclosed by C, Qx represents the partial derivative of Q with respect to x, and Py represents the partial derivative of P with respect to y.
In our case, the rectangle with vertices at (0,0), (π/6, 0), (π/6, π/4), and (0, π/4) can be denoted as R.
Let's calculate the partial derivatives of P and Q:
P(x, y) = sin(6y),
Q(x, y) = cos(4x).
Taking the partial derivative of Q with respect to x (Qx):
Qx = -4sin(4x).
Taking the partial derivative of P with respect to y (Py):
Py = 6cos(6y).
Now, we can evaluate the double integral using Green's Theorem:
Flux = ∬R (Qx - Py) dA
= ∫[0, π/6]∫[0, π/4] (-4sin(4x) - 6cos(6y)) dy dx.
Integrating with respect to y first:
Flux = ∫[0, π/6] [∫[0, π/4] (-4sin(4x) - 6cos(6y)) dy] dx
= ∫[0, π/6] [-4sin(4x)y - 6cos(6y)y]∣[0, π/4] dx
= ∫[0, π/6] [-4sin(4x)(π/4) - 6cos(6(π/4))(π/4)] dx
= -π/4 ∫[0, π/6] [sin(4x) + cos(9π/4)] dx
= -π/4 [(-1/4)cos(4x) + (1/9)sin(9π/4)]∣[0, π/6]
= -π/4 [(-1/4)cos(4(π/6)) + (1/9)sin(9π/4) - (-1/4)cos(0) + (1/9)sin(0)]
= -π/4 [(-1/4)cos(2π/3) + (1/9)sin(9π/4) - (-1/4) + 0]
= -π/4 [(-1/4)(-1/2) + (1/9)(-√2/2) + 1/4]
= -π/4 [1/8 - √2/18 + 1/4]
= -π/4 [5/8 - √2/18]
= -5π/32 + √2π/72.
Therefore, the outward flux of F across the closed curve C is -5π/32 + √2π/72.

How could you use the function y = sin 2x to find the zeros of y = tan 2x
To find the zeros of y = tan(2x), we need to solve the equation sin(2x) = 0 to determine the x-values where sin(2x) is zero. These x-values will correspond to the zeros of the function tan(2x).
To find the zeros of the function y = tan(2x), we can utilize the fact that tan(x) is equal to sin(x)/cos(x).
Given y = tan(2x), we can rewrite it as:
y = sin(2x) / cos(2x)
Now, let's consider the numerator of this expression, which is sin(2x). If we set sin(2x) equal to zero, we can determine the values of x that make the numerator zero:
sin(2x) = 0
By solving this equation, we can find the zeros of sin(2x). The solutions will be the values of x for which sin(2x) equals zero.
Similarly, we can look at the denominator of the expression y = sin(2x) / cos(2x), which is cos(2x). If cos(2x) equals zero, the denominator will be zero, which leads to undefined values for y. These points will be vertical asymptotes of the function tan(2x).
To find the zeros of y = tan(2x), we need to solve the equation sin(2x) = 0 to determine the x-values where sin(2x) is zero. These x-values will correspond to the zeros of the function tan(2x).

Joses his yearly wages were $50 more than marks, so he earned 16,815.43. Yet he said his taxes are the same as marks. Is he right? How can you tell?
Answer:
No
Step-by-step explanation:
This depends on many other things but in a basic tax bracket, both Joses and Mark both fall under the 12% tax bracket. This is for individuals who make a yearly salary between $9,876 to $40,125, in which the taxes would be 12% of the yearly salary. Since this is percent based, their taxes would not be the same, they would be close but Mark would still end up paying a little bit more since he made more money.

what is the hypotenuse if the legs are 7 and 5
The hypotenuse of the triangle if the legs are 7 and 5 is 8.6.
What is Pythagorean Theorem?In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side. When the positive integer sides of a right triangle (let's say sides a, b, and c) are squared, the result is an equation known as a Pythagorean triple.
Given that the sides of the triangle are 7 and 5.
The Pythagorean Theorem is given as follows:
a^2 + b^2 = c^2
Substituting the values of a = 7 and b = 5 we have:
(7)^2 + (5)^2 = c^2
49 + 25 = c^2
c^2 = 72
c = 8.6
Hence, the hypotenuse of the triangle if the legs are 7 and 5 is 8.6.

Variables y and x have a proportional relationship, and y = 21 when x = 14.
What is the value of x when y = 12?
Enter your answer in the box.
x =
please help
Answer:
18
Step-by-step explanation:
We know that y is 1.5 times x, so when x = 12, y = (1.5)(12)=18
This directly proportional relationship between p and q is written as p∝q where that middle sign is the sign of proportionality. The value of x is 8, when the value of y is 12.
What is the directly proportional and inversely proportional relationship?Let there are two variables p and q
Then, p and q are said to be directly proportional to each other if
p = kq
where k is some constant number called the constant of proportionality.
This directly proportional relationship between p and q is written as p∝q where that middle sign is the sign of proportionality.
In a directly proportional relationship, increasing one variable will increase another.
Now let m and n be two variables.
Then m and n are said to be inversely proportional to each other if
\(m = \dfrac{c}{n} \\\\ \text{or} \\\\ n = \dfrac{c}{m}\)
(both are equal)
where c is a constant number called the constant of proportionality.
This inversely proportional relationship is denoted by
\(m \propto \dfrac{1}{n} \\\\ \text{or} \\\\n \propto \dfrac{1}{m}\)
As visible, increasing one variable will decrease the other variable if both are inversely proportional.
Given Variables y and x have a proportional relationship, therefore, we can write,
y ∝ x
y = k × x
21 = k × 14
21/14 = k
k = 1.5
Therefore, the equation for the relationship between x and y can be written as,
y = 1.5x
now, the value of x when the value of y is 12 is,
12 = 1.5 × x
x = 8
Hence, the value of x is 8, when the value of y is 12.

The 15th term of the geometric progression is 9,565,94.
What is the 15th term of the geometric progression?A geometric progression can be expressed as an = a1rn-1 for some a1 and r. You are told that a2 * a4 = 2a5 and a1 + a2 + a3 + a4 = 80.
From the first equation, a2 = a1 r, a4 = a1 r3, and a5 = a1 r4. This tells us that
a1 r a1 r3 = 2 a1 r4
The r's and one a1 cancel leaving a1 = 2.
Now, plugging similarly into a1 + a2 + a3 + a4 = 80,
2 + 2r + 2r2 + 2r3 = 80
r3 + r2 + r + 1 = 40
In general, the easiest way to solve a cubic is by graphing, but here you know the answer will be a small integer, so just try a few. If we try r=3, we get 27 + 9 + 3 + 1 = 40 so r = 3.

If the perimeter of a square is 280 feet, how long is each side of the square?
The length of each side of the square is 280/4 = 70 feet.
The perimeter of a square is the total length of all the sides of the square added together. Since the perimeter of this square is 280 feet, this means that if we add up the length of all four sides, the total length is 280 feet. Therefore, we can divide the perimeter (280 feet) by the number of sides (4) in order to calculate the length of each side. This means that the length of each side of the square is 280/4 = 70 feet. Therefore, the length of each side of the square is 70 feet. By dividing the perimeter of the square by the number of sides, we can easily calculate the length of each side of the square.
