The perimeter of the triangle is 96, rounded to the nearest hundredth.
To calculate the perimeter of the triangle, we need to first calculate the length of the hypotenuse.
The hypotenuse of a right triangle is calculated using the Pythagorean theorem, which states that the square of the hypotenuse is equal to the sum of the squares of the two sides.
Therefore, for this triangle, we have:
(Hypotenuse)² = (24)² + (32)²
Therefore, the Hypotenuse = √(24² + 32²)
Hypotenuse = √(576 + 1024)
Hypotenuse = √1600
Hypotenuse = 40
To calculate the perimeter, we need to add up all three sides of the triangle.
the perimeter = 24 + 32 + 40
the perimeter = 96
Therefore, the perimeter of the triangle is 96, rounded to the nearest hundredth.

find the exact length of the curve. x = y4/8 + 1/4y2 , 1 ≤ y ≤ 2
The curve's approximate length is 33/16, as mentioned throughout the paragraph.
With an example, what is a curve?Curved shapes are those composed entirely of curves. A curved form, such as a circle, an ellipse, a parabola, or an arc, can be two-dimensional. Three-dimensional objects like sphere, cones, and cylinders can also have curved forms. A curved line is one that is not straight. A curve results from a point that is not moving in a straight line.
We'll use the following formula to get the angle of a function:
[tex]\begin{aligned}& L=\int d s \\& d s=\sqrt{1+\left(\frac{d x}{d y}\right)^2} d y\end{aligned}[/tex]
Let's now calculate x's derivative:
[tex]\begin{aligned}& \frac{d x}{d y}=\frac{4}{8} y^3-\frac{2}{4} \frac{1}{y^3} \\& =\frac{1}{2}\left(y^3-\frac{1}{y^3}\right)\end{aligned}[/tex]
Okay, now enter this into the ds formula to obtain:
[tex]d s=\sqrt{1+\frac{1}{4}\left(y^3-\frac{1}{y^3}\right)^2}[/tex]
Observe that:
[tex]\begin{aligned}& 1+\frac{1}{4}\left(y^3-\frac{1}{y^3}\right)^2=1+\frac{1}{4} y^6-\frac{1}{2}+\frac{1}{4 y^6} \\& =\left(\frac{1}{2} y^3+\frac{1}{2} y^{-3}\right)^2\end{aligned}[/tex]
The integral will now be easier to understand:
[tex]\begin{aligned}& L=\int_1^2 \sqrt{\left(\frac{1}{2} y^3+\frac{1}{2} y^{-3}\right)^2} d y=\int_1^2 \frac{1}{2} y^3+\frac{1}{2} y^{-3} d y \\& =\left[\frac{1}{8} y^4-\frac{1}{4} y^{-2}\right]_2^1 \\& =\frac{33}{16}\end{aligned}[/tex]

30 hours of use by the Washington family sprinkler and 35 hours of use by the Bennett family sprinkler.
We can find how long was each sprinkler used by substitution method.
Let W = hours of use by the Washington family
65 - W = hours of use by the Bennett family
According to the question we get
15W + 40(65 -W) = 1850
15W + 2600 - 40W = 1850
-25W = -750
W = 30
Now, put the value of W in 65 - W to calculate the hours used by the Bennett family

a 95% confidence interval for the true proportion of math students who prefer to use a handheld calculator versus computer software for computations is (0.751, 0.863). is it reasonable to believe more than 75% of math students prefer to use a handheld calculator versus computer software for computations?
It is reasonable to believe that more than 75% of math students prefer to use a handheld calculator versus computer software for computations because the lower bound of the confidence interval, 0.751, is above 0.75.
To determine this:
A 95% confidence interval for a proportion gives us an estimate of the range of values where the true proportion is likely to fall. The interval (0.751, 0.863) means that we are 95% confident that the true proportion of math students who prefer to use a handheld calculator versus computer software for computations falls between 0.751 and 0.863.
Given this information, it is reasonable to believe that more than 75% of math students prefer to use a handheld calculator versus computer software for computations because the lower bound of the confidence interval, 0.751, is above 0.75.
In other words, based on the sample data and the construction of the confidence interval, there is strong evidence that the true proportion of math students who prefer to use a handheld calculator is above 75%.
It's important to note that the confidence interval is only an estimate of the true proportion, and it's possible that the true proportion is not exactly within this interval. However, the 95% confidence level means that if we were to repeat the study many times, in about 95% of the cases, the interval would contain the true proportion.

how do I solve this?
Answer:
x = 13
Step-by-step explanation:
to solve this question you must know that angles in a triangle add up to 180 degrees
therefor 180 = 43 + 62 + (7x-16)
solve for x
180 = 43 + 62 + (7x-16)
180 = 105 + (7x-16)
Now, we can subtract 105 from both sides to get
75 = 7x-16
Next, we can add 16 to both sides to get
91 = 7x
Finally, we can divide both sides by 7 to get
x = 91/7
x = 13
So the value of x that satisfies the equation is 13
Answer:
x = 13
Step-by-step explanation:
Interior angles of a triangle sum to 180°. Therefore:
[tex]\implies 62^{\circ}+43^{\circ}+(7x-16)^{\circ}=180^{\circ}[/tex]
[tex]\implies 62+43+(7x-16)=180[/tex]
[tex]\implies 105+7x-16=180[/tex]
[tex]\implies 7x+89=180[/tex]
[tex]\implies 7x+89-89=180-89[/tex]

In the diagram, each of the three identical circles touch the other two. The circumference of each circle is 36. What is the perimeter of the shaded region?
The perimeter of the shaded region is 18 units.
The circumference of a circle is defined as the linear distance around it. In other words, if a circle is opened to form a straight line, then the length of that line will be the circle's circumference.
The result of the lengths of the sides is the perimeter of any polygon. In the case of a triangle: Perimeter = Sum of the three sides.
If we connect the centers of the circles, this will form an equilateral triangle.
The two sides of this triangle meeting at any vertex will pass through the points of tangency where one circle meets the other two, these two tangent points form the endpoints of one side of the shaded region.
Since the vertex angle of the triangle = 60°, then the arc formed by one side of the shaded region
= 1/6 the circumference of the circle
= 1/6 × 36
= 6 units
So, the perimeter of the shaded region is 3 times this
= 3 × 6
= 18 units
Therefore, the perimeter of the shaded region is 18 units.

an automobile manufacturer claims that their van has a 28.228.2 miles/gallon (mpg) rating. an independent testing firm has been contracted to test the mpg for this van. after testing 2727 vans they found a mean mpg of 28.028.0 with a standard deviation of 2.62.6. is there sufficient evidence at the 0.010.01 level that the vans underperform the manufacturer's mpg rating? assume the population distribution is approximately normal.
The p-value is <0.01, reject the null hypothesis, vans underperform the manufacturer's mpg rating.
What is null hypothesis ?
The null hypothesis is a statement that there is no statistical significance between the results of an experiment and a certain theoretical prediction or postulate. It is usually denoted by H0 and it is a statement of "no effect" or "no difference".
The null hypothesis is that the mean mpg of the vans is equal to the manufacturer's rating of 28.228.2 mpg, and the alternative hypothesis is that the mean mpg of the vans is less than the manufacturer's rating.
We can use the t-test statistic to determine the probability of observing a sample mean as extreme or more extreme than the one computed from the data, assuming that the null hypothesis is true.
The t-test statistic is: (sample mean - population mean) / (standard deviation/sqrt(sample size)) = (28.028.0 - 28.228.2) / (2.62.6 / sqrt(2727)) = -3.34
The p-value is the probability of observing a t-value as extreme or more extreme than -3.34, assuming that the null hypothesis is true. With a sample size of 2727, we can use a t-distribution table to find that the p-value is less than 0.01.

The area of the triangle APB is 6.75 square inches.
We know that PA=PB=PC and that PC is perpendicular to FD. Thus C will be the midpoint of FD.
Draw a perpendicular from P to AB, let the point of intersection be Q.
We know that CQ = DB = 6 inches
That is PC + PQ = 6 inches
PQ = (6 - PC) inches
Consider triangle APQ, it is a right angled triangle, right angled at Q. So using Pythagorean theorem
PA² = PQ² + AQ²
PA² = (6 - PC)² + (AB/2)²
PA² = (6 - PA)² + (6/2)²
PA² = 36 - 12PA + PA² + 9
12PA = 45
PA = 3.75
So PA = PB = PC = 3.75 inches
Also PQ = 6 - PC = 2.25 inches
The area of a triangle can be found by using the formula:
area = (base * height) / 2.
In this case, the base, AB is equal to the length of the side of the square, which is 6 inches, and the height is equal to PQ. So the area of triangle APB is

Triangle $ABC$ has vertices $A(0, 8)$, $B(2, 0)$, $C(8, 0)$. A line through $B$ cuts the area of $\triangle ABC$ in half; find the sum of the slope and $y$-intercept of this line.
By applying a linear equation, it is concluded that the slope of the line is 2 and the y-intercept is -4
A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is y = mx + k, where m is the slope of the line and k is the y-intercept.
First, we draw a triangle ABC whose vertices are A(0, 8), B(2, 0),C(8, 0)
Then we determine point D as the midpoint of AC, so D(4,4)
Now we use B(2,0) and D(4,4) to determine slope of the line (m):
m = (y₂-y₁) / (x₂-x₁)
= (4-0) / (4-2)
