Given an isosceles triangle with a base length of 30 and a median (drawn from the vertex
angle) length of 21, what is the length of a leg?
The length of each leg is 14.69 in the triangle
In an isosceles triangle, the median drawn from the vertex angle also acts as an altitude, dividing the triangle into two congruent right triangles.
Let the length of one of the legs of the triangle "x".
Using the Pythagorean theorem, we can write:
x²+ (15)² = (21)²
x² + 225 = 441
x² = 441 - 225
x² = 216
Taking the square root of both sides, we find:
x = √216
x =14.69
Therefore, the length of each leg is 14.69 in the triangle

Answer:
y = -1.5x + 3
Step-by-step explanation:
gradient = (-3 - 0) / (4 - 2) = -3/2 = -1.5.
equation on line through two points is given by
y - y1 = m (x - x1)
where y1 and x1 are the coordinates of the point and m is the gradient.
we can choose either point to use in the equation.
y - 0 = -1.5 (x - 2) = -1.5x + 3
y = -1.5x + 3
More than two-thirds of undergraduate students who graduated with a bachelor's degree had student loan debt. The average student loan debt among these graduating seniors was $28,654. The average interest rate on student loans was 6.1%. How much interest did a student with $28,654 in student loan debt pay in the first year? Round to the nearest cent.
The interest paid for the loan is $1748
Given that there is a 6.1% interest rate for a loan of $28,654 in student loan debt pay in the first year,
We need to find the interest paid for the same.
So,
Simple Interest = principal × time × rate / 100
= 28654 × 1 × 6.1 / 100
= 28654 × 0.061
= 1747.894

The masses in kilograms of 20 bags of maize were;90,94,96,98,99,102,105,91,102,99,105,94,99,90,94,99,98,96,102,and 105.i state the mode ii calculate the mean mass per bag
The mean mass per bag is 99 kilograms.
The mode is the value that appears most frequently in a dataset. In the given dataset of bag masses, the mode would be the mass value that occurs most often. Let's find the mode.
The masses of the bags are:
90, 94, 96, 98, 99, 102, 105, 91, 102, 99, 105, 94, 99, 90, 94, 99, 98, 96, 102, and 105.
To find the mode, we can simply count the frequency of each mass value and identify the one that appears most often:
90 appears twice
94 appears three times
96 appears two times
98 appears two times
99 appears four times
102 appears three times
105 appears three times
91 appears once
Therefore, the mode in this dataset is 99, as it appears most frequently.
To calculate the mean mass per bag, we need to sum up all the masses and divide by the number of bags. Let's calculate it:
Sum of masses = 90 + 94 + 96 + 98 + 99 + 102 + 105 + 91 + 102 + 99 + 105 + 94 + 99 + 90 + 94 + 99 + 98 + 96 + 102 + 105
Sum of masses = 1980
Number of bags = 20
Mean mass per bag = Sum of masses / Number of bags
Mean mass per bag = 1980 / 20
Mean mass per bag = 99 kilograms
Therefore, the mean mass per bag is 99 kilograms.

Calculating the values of a and nFrom the question, we have the following parameters that can be used in our computation:
f(x) = 2xⁿ + ax² - 6 is divided by (x - 1), the remainder is -7f(x) = 2xⁿ + ax² - 6 is divided by (x + 3), the remainder is 129This means that
f(1) = 7
f(-3) = 129
So, we have
f(1) = 2(1)ⁿ + a(1)² - 6
f(-3) = 2(-3)ⁿ + a(-3)² - 6
Evaluate
f(1) = 2 + a - 6
f(-3) = 2(-3)ⁿ + a(-3)² - 6
Recall that
f(1) = -7 and f(-3) = 129
So, we have
2 + a - 6 = -7
2(-3)ⁿ + 9a - 6 = 129
This gives
a = -3
Recall that
2(-3)ⁿ + 9a - 6 = 129

What is integration?Integration is the reverse of differentiation
a. Since we want to find the substitution in order to evaluate the following integrand ∫[x/(6x² + 5)²]dx, we proceed as follows
In the integrand ∫[x/(6x² + 5)²]dx, we see that the other function is the polynomial in the denominator which is (6x² + 5). So, we make the substitution u = (6x² + 5)
b. To rewrite the integrand in terms of u so that ∫[x/(6x² + 5)²]dx is int he form ∫f(u)du, we proceed as follows
Since integrand ∫[x/(6x² + 5)²]dx and u = 6x² + 5. Differentiation u with respect to x, we have that
du/dx = d(6x² + 5)/dx
= d(6x²)/dx + d5/dx
= 12x + 0
= 12x
So, du/dx = 12x
xdx = du/12
So, substituting this into the integrand, we have that
∫[x/(6x² + 5)²]dx = ∫[x/u²]dx
= ∫[xdx/u²]
= ∫[du/12/u²]
= ∫[du/12u²]

Answer:
[tex]f(u)=\dfrac{1}{12u^5}[/tex]
Step-by-step explanation:
Integration by substitution is a technique used to simplify the integration of complex functions. It involves writing part of the function in terms of a new variable u, where u is some function of x.
Given integral:
[tex]\displaystyle \int \dfrac{x}{(6x^2+5)^5}\; \text{d}x[/tex]
Substitute u for 6x² + 5.
Differentiate u with respect to x and rearrange the equation to isolate dx:
[tex]\dfrac{\text{d}u}{\text{d}x}=12x \implies \text{d}x=\dfrac{1}{12x}\; \text{d}u[/tex]
Substitute the expressions for u and dx into the original expression to rewrite the original integral in terms of u and du:
[tex]\begin{aligned}\displaystyle \int \dfrac{x}{(6x^2+5)^5}\; \text{d}x &= \int \dfrac{x}{u^5} \cdot \dfrac{1}{12x}\; \text{d}u\\\\&= \int \dfrac{1}{12u^5}\; \text{d}u\\\\\end{aligned}[/tex]

He believed that this movement needed a new language of art, one that wasn't tied to emblematic forms.
Kandinsky's appearance atnon-objective oil was told by his spiritual beliefs and his desire to express the inner nature of effects. As he writes in Concerning the Spiritual in Art," The artist must have commodity to say, for mastery over form isn't his thing but rather the adapting of form to its inner meaning"( Kandinsky, 1977,p. 10). He believed that art should be a spiritual expression and that the inner world of the artist should be restated into visual language.
Kandinsky wrote considerably about color in Concerning the Spiritual in Art. He believed that color had its own language and could convey feelings and ideas. As he writes," Color is a means of plying direct influence upon the soul. Color is the keyboard. The eye is the hammer. The soul is the piano, with its numerous strings"( Kandinsky, 1977,p. 43).

Solve the following inequality, indicate the number of solutions and plot the solutions on a number line.
d. 3(x + 3) + 12 ≤ 3x + 28
Let's start by simplifying the left side of the inequality:
3(x+3) + 12 <= 3x + 28
3x + 9 + 12 <= 3x + 28
3x + 21 <= 3x + 28
Subtracting 3x from both sides, we get:
21 <= 28
This is a true statement, which means that the inequality is true for all values of x. In other words, there are infinitely many solutions.
To represent this graphically, we can draw a number line and shade in all values of x for which the inequality is true. Since it's true for all values of x, we shade in the entire number line:
<=======()------------------->
In this number line, the open circle () indicates that the inequality is not true for that particular value (in this case, there is no specific value for x that makes the inequality false). The arrow indicates that the inequality is true for all values of x to the left and right of the open circle.
In summary, the inequality 3(x+3)+12 <= 3x+28 is true for all values of x, and there are infinitely many solutions.

A certain television is advertised as a 85-inch TV (the diagonal length). If the width of the TV is 67 inches, how tall is the TV? Round to the nearest tenth of an inch.
The height of the TV is approximately 52.3 inches when rounded to the nearest tenth of an inch.Hence, the TV is approximately 52.3 inches tall.
To find the height of the TV, we can use the Pythagorean theorem, which states that the square of the hypotenuse (the diagonal) of a right triangle is equal to the sum of the squares of the other two sides.
In this case, the width and height of the TV form the legs of a right triangle, with the diagonal as the hypotenuse.
Let's denote the height of the TV as h. According to the Pythagorean theorem:
h² + 67² = 85²
Simplifying the equation, we have:
h² + 4489 = 7225
Subtracting 4489 from both sides, we get:
h² = 2736
Taking the square root of both sides, we find:

= -15y^8/(-5y^5)
= 3y^3
So, the simplified expression is 3y^3.
