If X = 6 cm and Z = 10 cm, what is the length of Y?
To find the length of Y in a right triangle given X = 6 cm and Z = 10 cm, we can use the Pythagorean theorem. By substituting the values into the formula Y = √(X² + Z²), we find that the length of Y is approximately 11.66 cm.
Explanation:To find the length of Y, we can use the Pythagorean theorem. Since X and Z are the lengths of the legs of a right triangle, Y represents the length of the hypotenuse.
Using the formula: Y = √(X² + Z²), we can substitute the given values: Y = √(6² + 10²) = √(36 + 100) = √136 = 11.66 cm.
Therefore, the length of Y is approximately 11.66 cm.

Consider the effect of the transformation (x, y) → (x, 2y) on the parallelogram ABCD with vertices A(0, 0), B(1, 1), C(3, 1), and D(2, 0). Select True or False for each statement.
The transformation (x, y) → (x, 2y) doubles the y-coordinates of the parallelogram ABCD vertices, resulting in a new parallelogram with doubled height and consequently doubled area, demonstrating that the change in height is proportional to the original height.
Explanation:The question posed relates to the effect of a transformation on the coordinates of a parallelogram's vertices. Specifically, we look at the transformation (x, y) → (x, 2y), which stretches the y-coordinates of the vertices while keeping the x-coordinates unchanged. For the given parallelogram ABCD with vertices A(0, 0), B(1, 1), C(3, 1), and D(2, 0), we apply the transformation to each vertex:
Vertex A(0, 0) becomes A'(0, 0 × 2) = A'(0, 0)Vertex B(1, 1) becomes B'(1, 1 × 2) = B'(1, 2)Vertex C(3, 1) becomes C'(3, 1 × 2) = C'(3, 2)Vertex D(2, 0) becomes D'(2, 0 × 2) = D'(2, 0)The transformation doubles the height (y-coordinate) of the parallelogram, while the base (x-coordinate) remains the same. Consequently, the area of the parallelogram also doubles, confirming that the change in height is proportional to the original height. By applying the transformation to a simple geometric figure, students can visualize and understand the properties of transformations and their effects on the shapes.

find the length of side x in simplest form with a rational denominator
Given:
The figure contains a right triangle.
The two angles of the triangle are 45° each.
The length of one leg is 3 units.
The length of the hypotenuse is x units.
We need to determine the value of x.
Value of x:
The value of x can be determined using the formula,
[tex]cos \ \theta=\frac{adj}{hyp}[/tex]
where [tex]\theta=45^{\circ}[/tex], adj = 3 and hyp = x.
Substituting these values, we get;
[tex]cos \ 45^{\circ}=\frac{3}{x}[/tex]
Simplifying, we get;
[tex]x=\frac{3}{cos \ 45^{\circ}}[/tex]
[tex]x=\frac{3}{\frac{\sqrt{2}}{2}}[/tex]
[tex]x=3 \times \frac{2}{\sqrt{2}}[/tex]
[tex]x=\frac{6}{\sqrt{2}}[/tex]
Thus, the value of x is [tex]x=\frac{6}{\sqrt{2}}[/tex]
A person invests 5500 dollars in a bank. The bank pays 6.75% interest compound monthly. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 13200 dollars?
We have been given that a person invests 5500 dollars in a bank. The bank pays 6.75% interest compound monthly. We are asked to find the time that will take the amount to 13,200 dollars.
We will use compound interest formula to solve our given problem.
[tex]A=P(1+\frac{r}{n})^{nt}[/tex], where,
A = Final amount,
P = Principal amount,
r = Annual interest rate in decimal form,
n = Number of times interest is compounded per year,
t = Time in years.
[tex]6.75\%=\frac{6.75}{100}=0.0675[/tex]
Upon substituting our given values in above formula, we will get:
[tex]13200=5500(1+\frac{0.0675}{12})^{12\cdot t}[/tex]
[tex]13200=5500(1+0.005625)^{12\cdot t}[/tex]
[tex]13200=5500(1.005625)^{12\cdot t}[/tex]
[tex]\frac{13200}{5500}=(1.005625)^{12\cdot t}[/tex]
[tex]2.4=(1.005625)^{12\cdot t}[/tex]
Now we will take natural log on both sides.
[tex]\text{ln}(2.4)=\text{ln}((1.005625)^{12\cdot t})[/tex]
Using natural log property [tex]\text{ln}(a^b)=b\cdot \text{ln}(a)[/tex], we will get:
[tex]\text{ln}(2.4)=12t\cdot \text{ln}(1.005625)[/tex]
[tex]t=\frac{\text{ln}(2.4)}{12\cdot \text{ln}(1.005625)}[/tex]
[tex]t=13.00635[/tex]
Upon rounding to nearest tenth, we will get:
[tex]t\approx 13.0[/tex]
Therefore, it will take approximately 13.0 years for the amount to reach $13200.

At a post office, the weight of the mail at 10.00 a.M was 80 pounds. Two hours later, the weight of the mail had increased by 30%. Find the weight of the mail at noon.
Answer: The weight of mail at noon is 104 pounds.
Step-by-step explanation:
Given that , At a post office, the weight of the mail at 10.00 A.M was 80 pounds.
Two hours later, the weight of the mail had increased by 30%.
Since , time after 2 hours of 10 A.M would be 12 P.M which is known as noon.
Mathematically , the weight of the mail at noon = (Weight at 10 AM) +30% of (Weight at 10 AM)
= 80 + 0.30(80) pounds
= 80 (1+0.30) pounds
= 80 (1.30) pounds
= 104 pounds
Hence, the weight of mail at noon is 104 pounds.

Answer:
[tex] volume = 2197 \pi~in.^3 \approx 6902.1~in.^3 [/tex]
Step-by-step explanation:
[tex] base~ area = 169 \pi~in.^2 [/tex]
The base of the cylinder is a circle.
The area of a circle is:
[tex] area = \pi r^2 [/tex]
We set the area equal to the formula and find the radius.
[tex] \pi r^2 = 169 \pi~in.^2 [/tex]
[tex]r^2 = 169~in.^2[/tex]
[tex]r = 13~in.[/tex]
The radius of the base is 13 inches. The height of the cylinder is also 13 inches.
[tex] volume = base~area \times height [/tex]
[tex]volume = 169 \pi~in.^2 \times 13~in.[/tex]
[tex] volume = 2197 \pi~in.^3 \approx 6902.1~in.^3 [/tex]
Let R be the region in the first quadrant of the xy-plane bounded by the hyperbolas xyequals1, xyequals9, and the lines yequalsx, yequals4x. Use the transformation x equals StartFraction u Over v EndFraction , y equals uv with ugreater than0 and vgreater than0 to rewrite the integral below over an appropriate region G in the uv-plane. Then evaluate the uv-integral over G.
To rewrite the integral over an appropriate region G in the uv-plane, we need to use the given transformation x = u/v and y = uv. The region G is defined by certain constraints on u and v, which can be found by solving the inequalities derived from the boundaries of R in the xy-plane. Finally, we can set up and evaluate the double integral over G.
Explanation:To rewrite the integral over an appropriate region G in the uv-plane, we need to use the given transformation x = u/v and y = uv. Let's consider each boundary of R separately:
For the hyperbola xy = 1, substituting the given transformations, we get (u/v)(uv) = 1, which simplifies to u^2 = v.For the hyperbola xy = 9, substituting the given transformations, we get (u/v)(uv) = 9, which simplifies to u^2 = 9v.For the line y = x, substituting the given transformations, we get uv = u/v.For the line y = 4x, substituting the given transformations, we get uv = 4(u/v).Now, we need to find the region G in the uv-plane that corresponds to R in the xy-plane. The region G is defined by the following constraints: u^2 ≤ v, 9v ≥ u^2, uv ≤ u/v, and uv ≥ 4(u/v). Combining these constraints, we get u^4 ≤ v^2 ≤ 9u^3 and u^2 ≤ 4v. The boundaries of G can be found by solving these inequalities.
To evaluate the integral over G, we need to determine the limits of integration for u and v. Once we have the limits, we can set up the double integral of the function over G and evaluate it.

Final answer:
The expression [tex]4^4(4^-7)(4[/tex]) simplifies to [tex]4^-2[/tex] by adding the exponents of the same base, resulting in a single exponent expression.
Explanation:
To simplify the expression [tex]4^4(4^-7)(4)[/tex] using a single exponent, you'll need to apply the rules of exponents. When you have the same base being multiplied, you can add the exponents. Start by looking at the terms 4^4 and 4^-7. The rule says to add the exponents when multiplying: 4 + (-7) = -3. So those two terms combine to make 4^-3.
Next, we have the single 4, which can also be written as 4^1 since any number to the power of 1 is itself. Now add the exponents again: -3 + 1. This gives us[tex]4^-2[/tex], which is the expression simplified with a single exponent.

Find the values of x and y using the given chord, secant, and tangent lengths.
Answer:
x = 15.65
y = 3.5
Step-by-step explanation:
Step 1
Find the equation for x and y
Equation for x is given as
x² = 7( 7+28) ..........Equation 1
14(14 + y) = x²........ Equation 2
Solving for Equation 1
x² = 7( 7+28)
x² = 7(35)
x² = 245
x = √245
x = 15.65
From Equation 1 , x² has been determined to be 245
Therefore we substitute 245 for y in Equation 2
14(14 + y) = x²........ Equation 2
14(14 + y) = 245
196 + 14y = 245
14y = 245 - 196
14y = 49
y = 49 ÷ 14
y = 3.5
