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]

Answer:

it's C my doods

Step-by-step explanation:

Yes, 9²+40²=41²

Pythagoras theorem states that, a right-angled triangle, the square of the one side is equal to the sum of the squares of the other two sides.

Pythagorean Triples where any 2 side the sum of the squares adds up to be equal the other side.

A triangle has side lengths are 40, 9 and 41

∵ 41 is the longest side length and that makes it the hypotenuse

The square of the two other sides is 9²+40² = 1,681

Also, 41² = 1,681

As we can see, the sum of the squares equal the square of the hypotenuse

Since this triangle follows the theorem, we can conclude that the triangle is a right triangle

#SPJ2

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.

Answer:

x=72 x = 7 2

Step-by-step explanation:

Answer:

x=7/2

Step-by-step explanation:

First, distribute the 9 on the left side  

9(3-2x)=2(10-8x)  

(9*3)+(9*-2x)= 2(10-8x)

27-18x= 2(10-8x)

Next, distribute the 2 on the right side

27-18x=(2*10)+(2*-8x)

27-18x=20-16x

Now, move all the numbers to one side of the equation, and the variables to the other.

27-18x=20-16x

Add 18x to both sides

27-18x+18x=20-16x+18x

27=20+2x

Subtract 20 from both sides

27-20=20-20+2x

7=2x

Now all the variables are on one side, and the numbers are on the other. x is still not by itself. It is being multiplied by 2. To undo this, divide both sides by 2

7/2=2x/2

7/2=x

Step-by-step 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. 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.

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:

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.

Answer:

Factoring completely would give you the answer of ( x+5) (x^3 +4).

Step-by-step explanation:

The factor are (x³ + 4) and (x + 5).

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

[tex]x^4[/tex] + 5x³ + 4x + 20

We can find the common factor between [tex]x^4[/tex] and 5x³.

So,

x³ (x + 5) _____(1)

And,

We can find the common factor between 4x and 20.

So,

4 (x + 5) ______(2)

From (1) and (2),

x³ (x + 5) + 4 (x + 5)

= (x³ + 4) (x + 5)

Thus,

The factor are (x³ + 4) and (x + 5).

Answer:

Length: 7 units

Width: 1 unit

Step-by-step explanation:

The length of rectangle is 7 units.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

let the length of rectangle be x.

Then, width of the rectangle = x - 6

Also, Area of rectangle = 7 units

So, length x width = 7

x(x- 6)= 7

x² - 6x = 7

x² -6x -7 =0

x² -7x + x - 7=0

x( x- 7) +1 (x- 7)= 0

(x+ 1)(x- 7)=0

x= -1 or 7.

Hence, the length of rectangle is 7 units.

Answer:

-23

Step-by-step explanation:

-23 is the answer

The sum of the two integers if they are 5 units apart on the number line, and their product is 126 is -23

System of equations are equations that contain unknown variables with more than 1 equation.

Let the required integers be x and y.

If two negative integers are 5 units apart on the number line, then;

x - y = 5
x = 5  + y

If their product is 126, hence:

x y = 126

Substitute

5+y(y) = 126
5y + y^2 = 126
y^2 + 5y - 126 = 0

Factorize
y^2 + 14y - 9y - 126 = 0
y(y + 14) - 9(y + 14) = 0
y = 9 and  - 14

Since the integers are negative, hence;

x =  5 + y
x = 5 - 14
x = -9

Sum = -14 + (-9)
sum = -23

Hence the sum of the two integers is -23

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.

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:

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.

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.
