the other two angles of the triangle must also be equal, which means that the other two sides of the triangle must be equal as well. the length of the shorter sides is [tex]y = 16 feet[/tex] .
What are the remaining sides are half as long in heptagon?Let's start by using the information given to write equations for the perimeter of the heptagon in terms of the length of the sides:
Let x be the length of the four equal sides, and y be the length of the remaining three sides, which are half as long. Then, we have:
Perimeter [tex]= 4x + 3y[/tex]
We also know that the perimeter is 88 feet, so we can set up the equation:
[tex]4x + 3y = 88[/tex]
Now we need to solve for y, which represents the length of the shorter sides.
We can simplify the equation by substituting y = (1/2)x:
[tex]4x + 3(1/2)x = 88[/tex]
Simplifying this expression, we get:
[tex]7x/2 = 88[/tex]
Multiplying both sides by 2/7, we get:
[tex]x = 32[/tex]
Now that we know x, we can find y by substituting it into the equation y [tex]= (1/2)x[/tex]:
[tex]y = (1/2)(32) = 16[/tex]
Therefore, the length of the shorter sides is [tex]y = 16[/tex] feet.

A water trough is 10 m long and has a cross-section in the shape of an isosceles trapezoid that is 40 cm wide at the bottom, 90 cm wide at the top, and has height 50 cm. If the trough is being filled with water at the rate of 0.1 m3/min, how fast (in m/min) is the water level rising when the water is 10 cm deep?
Answer:
Let's start by finding the volume of water in the trough as a function of its depth.
At a depth of h cm, the cross-sectional area of the water is an isosceles trapezoid with bases of length b1 = 40 + (h/5) cm and b2 = 90 + (h/2) cm, and height 50 cm. The average width of the trapezoid is (b1 + b2)/2 = 65 + (3h/10) cm. Therefore, the volume of water in the trough at this depth is:
V(h) = 10 m x [(65 + (3h/10)) / 100 cm] x h cm
Simplifying this expression, we get:
V(h) = (13/2000) h^2 m^3
Now, we can use the chain rule to find the rate of change of V with respect to time t, given that dV/dt = 0.1 m^3/min:
dV/dt = (dV/dh) x (dh/dt) = (26/2000) h (dh/dt)
At the moment when the water is 10 cm deep, we have:
h = 10 cm
dV/dt = 0.1 m^3/min
Plugging in these values, we get:
0.1 m^3/min = (26/2000) x 10 cm x (dh/dt)
Solving for dh/dt, we get:
dh/dt = 0.1 m^3/min / (26/2000) / 10 cm
dh/dt ≈ 0.192 m/min
Therefore, the water level is rising at a rate of approximately 0.192 m/min when the water is 10 cm deep.

A local doctor wants to test the effects of a new diet she decided to lower triglycerides on 10 randomly selected patients. The triglyceride level of each patient is checked twice, once before they start the diet, and again at three weeks after that time. The results are in the table below, (the photo). All data is in milligrams per deciliter (mg/dL).
The Null and alternative hypothesis for the study are (in the photo)
! Thank you , 100 points!!
A) test statistic T equals -1.952; P value, 0.0414. There is sufficient evidence to reject the null hypothesis of no difference between the triglyceride test levels.
B) test statistic, T equals 0.3619. P value, 0.6392. There is insufficient evidence to reject the null hypothesis of no difference between the triglyceride test levels.
C) test statistic, T = -1.952; p value, 0.0509. There is sufficient evidence to reject the no hypothesis of no difference between a triglyceride test levels.
D) test statistic T equals 0.3651. P value, 0.6425. There is insufficient evidence to reject the null hypothesis of no difference between the triglyceride test levels.
The correct answer is A) test statistic T equals -1.952; P value, 0.0414.
How would you define hypothesis?An assumption or concept is given as a hypothesis for the purpose of debating it and testing if it might be true. In the scientific process, the hypothesis is developed before any pertinent research—aside from a basic background review—has been conducted.
The null hypothesis that there is no difference between the triglyceride test levels is sufficiently refuted by the available data.
With 9 degrees of freedom and a significance threshold of 0.05, this can be ascertained by comparing the derived test statistic (T) with the critical value of t from the t-distribution table. We reject the null hypothesis if the estimated T value is in the rejection zone (i.e., T value is smaller than the critical value of t).
The computed T value in this instance is -1.952, which is in the rejection region (i.e., less than the critical value of t of -1.833). Hence, we get to the conclusion that there is enough data to imply that the new diet has an effect on lowering triglyceride levels and reject the null hypothesis that there is no difference between the triglyceride test levels.

Steps for solving t|u prove mt=mu
We may conclude after answering the presented question that As a equation result, we have demonstrated that mt = mu when t | u.
How to solve the problem?Make a note of the definition of t | u. It denotes the existence of an integer k such that u = tk.
To get mt = m, substitute u = tk into mt = mu (tk).
Rewrite m(tk) as (mt)k using the associative property of multiplication.
To get mt = (mt)k, substitute (mt)k for m(tk) in the equation mt = mu.
Multiply both sides by mt. If mt is greater than zero, we obtain 1 = k. If mt is zero, we must also have mu = 0, hence the equation holds.
Since 1 Equals k, we get u = tk = t(1) = t.
We get mt = mt by substituting u = t into the original equation mt = mu.
As a result, we have demonstrated that mt = mu when t | u.

What is perimeter :
Perimeter is a mathematical term that refers to the total distance around the boundary of a two-dimensional shape. It is the sum of the lengths of all the sides of the shape.
Property of circles:The property of circles states that "the tangents drawn from the same point on a circle are equal in length". It means that if two tangent lines are drawn from an external point to a circle, the length of both tangents will be equal.
Here we have
Tangents QR and QV from point Q
Tangents RS and ST from point S
Tangents VU and UT from point U
As we know,
The tangents drawn from the same point on a circle are equal in length
=> Tangent QR = QV --- (1) from point Q
=> Tangent RS = ST ----- (2) from point S
=> Tangent VU = UT ----- (3) from point U
From the figure,
The perimeter of decks = QR + RS + ST + TU + UV + VQ
From (1) (2) and (3)
=> QR + ST + ST + UV + UV + QR
