1. Is there a triangle with two right angles?
Answer:
A triangle can't have two right angles. If a triangle has two right angles, then the sum of its three angles will be more than the two right angles i.e. more than 180∘ which is impossible.
Answer:
No, it is not possible for a triangle to have two right angles because a triangle's angles add up to 180 degrees, and two right angles add up to 180. A triangle also has three angles, so the third angle cannot be 0 degrees.

Find the equation of the line that is parallel to y=-2/3x and contains the point (4,-8)
Answer:
y = (-2/3)x + 16/3
Step-by-step explanation:
Any line parallel to y = (-2/3)x has the same slope: (-2/3).
Then, in this pattern, y = (-2/3)x + c, where c is the y-intercept.
If (4, -8) lives on this new line, then:
-8 = (-2/3)(4) + c, and
-8 = -8/3 + c
This last equation is equivalent to -24/3 + 8/3 + c => -16/3 = -c.
Therefore the y-intercept is 16/3 = c, and the desired equation is
y = (-2/3)x + 16/3
Which expression is equivalent to the quantity five raised to the negative second power times three raised to the fifth power end quantity all raised to the negative second power?

find equations of the tangent line and of the normal line to the curve at the point . write the equations of the lines in the form .
The equations of the lines in the form y=mx+b are-
Tangent line: y = 240x - 215994Normal line: y = - 0.00417x + 9.75What is slope?A line's slope is described like the change in y coordinate to the change in x coordinate. The net y coordinate change is y, whereas the net x coordinate change is x.
Therefore the variation in y coordinate in relation to the variation in x coordinate is written as, dy/dx.
Now, as per the given conditions;
The equation of the line is y = (6 + 4x)²
Simplifying the equation;
y = (6 + 4x)²
= 36 + 48x + 16x²
y = 16x² + 48x + 36
Now, differentiate the equation to find the tangent slope;
dy/dx = 32x + 48
At the point (6,900),
dy/dx = 32(6) + 48 = 240
Let equation of the tangent at point (a,b) is;
(y - b) = m(x - a)
a = 6, b = 900, m = 240
y - 6 = 240(x - 900)
Write this in y = mx + b form,
y - 6 = 240x - 216000
y = 240x - 215994 (Equation of Tangent line)
The slope of the normal line = -(1/slope of the tangent line) (since they're both perpendicular to each other)
Slope of the normal line = -1/240
The, equation of the normal will become;
y - 6 = (-1/240)(x - 900)
y - 6 = (-x/240) + 3.75
y = (-1/240)x + 9.75
y = - 0.00417x + 9.75 (Equation of Normal line)
Thus, the equation for the normal and tangent has be found.

week. How much will you make in 4 weeks?
Answer:
$1425
Step-by-step explanation:
To find how much money you would make, we would first have to multiply the number of weeks worked by how many hours you work per week.
4 · 25 = 100
What this tells us is that in 4 weeks, you worked 100 hours in total. Now we can multiply total hours worked by how much you are paid per hour to get our answer.

an online retailer is shipping a shower curtain pole that is 13 feet long. their largest box is in the shape of a rectangular prism that is 10 ft × 9 ft × 8 ft. will the pole fit in the box?
Yes, the pole will fit in the box when kept diagonally.
In order to fit the pole in rectangular prism or cuboid, it has to be kept diagonally. Now, we need to calculate the length of body diagonal of cuboid. The length of body diagonal of cuboid should be greater than pole to fit it.
The length of body diagonal of cuboid can be calculated by the formula -
Diagonal = √(l² + b² + h²)
Keep the values in formula to find the diagonal of rectangular prism
Diagonal = √(10² + 9² + 8²)
Taking square of the three numbers to find the diagonal of rectangular prism
Diagonal = √100 + 81 + 64
Taking sum of numbers present on Right Hand Side of the equation
Diagonal = √245
Taking square root of the number
Diagonal = 15.65 feet
Hence, as the diagonal of rectangular prism is greater than shower curtain pole, it will definitely fit.

The mean repair cost for the stereos is (79.47, 91.56) with a 90% confidence interval.
What is the critical factor?The critical factor for a 90% confidence interval for the true mean repair cost for stereos is given by;
Critical factor = (x-μ)/(s/√n)
where, x = sample mean repair cost
s = standard deviation of a sample
n = sample of stereos
μ = critical value
We have been given that a researcher records the repair cost for 13 randomly selected stereos. a sample mean of $85.52 and a standard deviation of $10.81 are subsequently computed.
Since we don't know the population standard deviation, we used t statistics to create the 90% confidence interval in this case.
So, the 90% confidence interval for the true mean repair cost, μ is ;
⇒ P(-2.015 < t₅ < 2.015) = 0.90
{As the critical value of t at 5 degrees of freedom are -2.015 & 2.015 with P = 5%}
⇒ P(-2.015 < (x-μ)/(s/√n) < 2.015) = 0.90
⇒ P(-2.015×(s/√n) < (x-μ) < 2.015×(s/√n)) = 0.90
⇒ P(x - 2.015×(s/√n) < μ < x + 2.015×(s/√n)) = 0.90
90% confidence interval for
⇒ μ = (x - 2.015×(s/√n) , x + 2.015×(s/√n))
Here, x = $85.52, s = $10.81, and n = 13
⇒ μ = (85.52 - 2.015×(10.81/√13) , 85.52 + 2.015×(10.81/√13))
⇒ μ = (79.47, 91.56)

Answer:
11) KI = 28

Step-by-step explanation:
You want the base segment lengths KI and PR, given relations between those segments and the corresponding midsegment of the triangle.
MidsegmentA midsegment is a line segment that joins midpoints of other line segments, usually the midpoints of triangle sides or opposite sides of a quadrilateral. In the case of a triangle, the midsegment is parallel to the third side, and half its length. This relation is used to solve these problems.

Additional comment
As you can see here, there is no real reason to find the value of x, then substitute it back into the expression for the segment of interest. We can, and did, solve directly for the value of that expression.
As with any algebraic manipulation, any operation performed on one side of the equal sign must also be performed on the other side of the equal sign. When we say "subtract ()", we mean "subtract () from both sides of the equation."
In problem 11, x=-9. In problem 12, x=-8. Negative values of x work just fine, as long as the resulting segment lengths are positive.

Definitions
Prime number: A whole number greater than 1 that cannot be made by multiplying other whole numbers.
Prime Factorization: Prime numbers that multiply together to make the original number.
The first few prime numbers are: 2, 3, 5, 7, 11, 13, 17, ...
To find which prime numbers multiply together to make 252, begin by dividing 252 by the first prime number, 2:
⇒ 252 ÷ 2 = 126
As 126 is not a prime number, we need to divide again.
⇒ 126 ÷ 2 = 63
As 63 is not a prime number, and 63 is not divisible by 2, try dividing it by the next prime number, 3:
⇒ 63 ÷ 3 = 21
As 63 is not a prime number, divide again.
⇒ 21 ÷ 3 = 7
As 7 is a prime number, we can stop.
Therefore, 252 is the product of:
⇒ 252 = 2 × 2 × 3 × 3 × 7
As 2 and 3 appear twice, we can write these using exponents:
⇒ 252 = 2² × 3² × 7

The mean would change by subtracting 32 from the original mean of 65.3.The median would remain the same since subtracting a constant value does not affect the relative order of the data points.The standard deviation would remain the same since it is a measure of dispersion and does not depend on the shift of the data.The IQR would remain the same since it is based on the order statistics (including the median) and is not affected by a constant shift.b. When the new values (obtained after subtracting 32) are multiplied by 5/9:
The mean would change by multiplying the new mean by 5/9.The median would remain the same since scaling by a constant value does not affect the relative order of the data points.The standard deviation would change by multiplying the new standard deviation by 5/9 since it is a measure of dispersion and scales with the data.The IQR would change by multiplying the new IQR by 5/9 since it is based on the order statistics and scales with the data.c.

The mean and median would remain the same since the Celsius scale and Fahrenheit scale have a linear relationship, and shifting or scaling the data does not affect their relative values.The standard deviation would change by multiplying the new standard deviation by 5/9 since it scales with the data.The IQR would change by multiplying the new IQR by 5/9 since it scales with the data.Learn more about IQR here:
