Step-by-step explanation:

Answer:

∠B

∠Y

Step-by-step explanation:

we know that

In the right triangle ABC

[tex]tan(B)=\frac{AC}{BC}[/tex] ----> opposite side to angle B divided by the adjacent side to angle B

substitute the values

[tex]tan(B)=\frac{3}{4}[/tex]

Remember that

If two triangles are similar, then the corresponding sides are proportional and the corresponding angles are congruent

so

∠A=∠W

∠B=∠Y

∠C=∠Z

therefore

[tex]tan(B)=tan(Y)[/tex]

Base on the fact that the triangle ABC and WYZ are similar, the angles whose tangent equals 3 / 4 are ∠B and ∠Y

Similar triangle are only different in sizes but are of the same shape.

Similar triangles, corresponding sides are always in the same ratio. Corresponding angles of similar triangles are always congruent. Therefore,

∠A = ∠W

∠B = ∠Y

∠C = ∠Z

Therefore, let's find all angles in the similar triangles whose tangent is equal to 3 / 4 .

tan ∅ = opposite / adjacent

Since,

tan B = 3 / 4

Then

tan Y = 3 / 4

Therefore,

The angles whose tangent equals 3 / 4 are ∠B and ∠Y

For this case we have that the parts of a division are:

Dividend, divisor, quotient and remainder.

To make the division of polynomials, we must build a quotient that when multiplied by the divisor (and when the sign is changed), eliminate the terms of the dividend until reaching the remainder of the division.

It must be fulfilled that:

Answer:

Step-by-step explanation:

Final answer:

To solve the triangle with sides a=26, b=29, and angle A=58 degrees, apply the Law of Sines to find another angle, use the sum of angles to find the third angle, and then the Law of Cosines to find the remaining side, ensuring all conditions are satisfied for a valid triangle.

Explanation:

To find all solutions for a triangle given a=26, b=29, and A=58 degrees, we use the Law of Sines, which relates the lengths of sides to the sine of their opposite angles. Since sin A > sin a (opposite side to angle A) would result in no solution and considering the given values, we don't encounter this issue. Instead, we have:

sin B / b = sin A / a

Rearranging for B, we have:

B = sin⁻¹(sin A / a × b)

Plugging in our numbers:

B = sin⁻¹((sin 58°) / 26 × 29)

Once B is calculated, we can find angle C since the interior angles of a triangle sum to 180 degrees. Following that, we can use the Law of Cosines to find the third side, c. The process is:

After finding all angles and sides, verify the solution by checking if the interior angles sum to 180 degrees and the sides satisfy the Triangle Inequality Theorem.

Substitute the value for y as 450

450=-5x+1

Solve for x

450-1=-5x

449=-5x

89.8=-x

x=-89.8

Answer:

x = 290

Step-by-step explanation:

The x- intercept is the point on the x- axis where the line crosses.

substitute y = 0 into the equation and solve for x

- 5x + 1450 = 0 ( subtract 1450 from both sides )

- 5x = - 1450 ( divide both sides by - 5 )

x = 290 ← x- intercept

line crosses x- axis at (290, 0)

Answer:

The new equation is y= (x-3)

Step-by-step explanation: we know that   the point (1, 1) is moved to (4,1).

So, the rule of the translation is: [tex](x,y) -----> (x+3, y)[/tex]

that means  the translation is 3 units to the right

Answer:

[tex]y=|x-3|[/tex]

Step-by-step explanation:

The parent absolute function is

[tex]y=|x|[/tex]

The graph of y= |x| is translated so that the point (1, 1) is moved to (4,1). It means the rule of translation is

[tex](x,y)\rightarrow (x+3,y)[/tex]

it means the graph of y=|x| translated 3 units right. So, the new vertex of the function is (3,0).

The vertex form of an absolute function is

[tex]y=|x-h|+k[/tex]

The new vertex of the function is (3,0). Substitute h=3 and k=0 in the above equation.

[tex]y=|x-3|+0[/tex]

[tex]y=|x-3|[/tex]

Therefore, the required equation is y=|x-3|.

Answer:

[tex]A(t)=A_{0}e^{\frac{ln(\frac{1}{2})}{22}t}[/tex]

Step-by-step explanation:

This half life exponential decay equation goes by the formula:

[tex]A(t)=A_{0}e^{kt}[/tex]

Where

[tex]k=\frac{ln(\frac{1}{2})}{Half-Life}[/tex]

Since half life is given as 22, we plug that into "Half-Life" in the formula for k and then plug in the formula for k into the exponential decay formula:

So,

[tex]k=\frac{ln(\frac{1}{2})}{Half-Life}\\k=\frac{ln(\frac{1}{2})}{22}[/tex]

Now

[tex]A(t)=A_{0}e^{\frac{ln(\frac{1}{2})}{22}t}[/tex]

third choice is correct.

Answer:

1 centimeter = 10 millimeters  

Step-by-step explanation:

we have to find about how many millimeters are in a centimeter.

We know that  1 centimeter = 10 millimeters

or 10 millimeters  = 1 centimeter

divide both sides by 10

or \frac{10}{10} millimeters  = \frac{1}{10} centimeter

or 1 millimeters  = 0.1 centimeter

But we need millimeters  in centimeters so we should write :

final answer as 1 centimeter = 10 millimeters.

Answer:

5 by 10

Step-by-step explanation:

We know that the equation of a perimeter of a recangle is 2(l)+2(w), l being length and w being width. We know that l=2w. So the perimeter of this room would be:

2(2w)+2(w)=30

4w+2w=30

6w=30

w=5

l=2w

l=10

the dimensions are 5 by ten

The dimensions of the rectangular room with a perimeter of 30 meters and length twice its width are 5 meters wide and 10 meters long.

The subject matter of your question falls into the category of Mathematics, specifically dealing with basic geometry and algebra. You want to find the width and length of a rectangular room given that it is twice as long as it is wide, and that its perimeter is 30 meters.

The perimeter P of a rectangle is calculated by the formula 2L + 2W = P, where L is the length and W is the width. Since the length is given as twice the width, we can substitute 2W for L in the formula and get 2(2W) + 2W = 30, which simplifies to 6W = 30. Solving for W, we find that W = 5. Therefore, the width of the room is 5 meters and the length of the room is 2W = 2*5 = 10 meters.

Answer:

The center is (-3,2) and the radius is r=2

Step-by-step explanation:

The general equation of the given circle is

[tex]x^2+6x+y^2-4y=-9[/tex]

Add the square of half the coefficient of the linear terms to both sides of the equation to obtain;

[tex]x^2+6x+3^2+y^2-4y+(-2)^2=-9+3^2+(-2)^2[/tex]

[tex]x^2+6x+9+y^2-4y+4=-9+9+4[/tex]

[tex]x^2+6x+9+y^2-4y+4=4[/tex]

The quadratic trinomials in x and y on the left side of the equations are perfect squares.

We factor to obtain;

[tex](x+3)^2+(y-2)^2=4[/tex]

[tex](x--3)^2+(y-2)^2=2^2[/tex]

Comparing to:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

The center is (-3,2) and the radius is r=2

To complete the square and put the equation into graphing form, group x's and y's, add appropriate constants to each group, and rewrite. The circle's equation becomes (x + 3)² + (y - 2)² = 4, with the center at (-3, 2) and a radius of 2.

To complete the square for the equation x² + 6x + y² - 4y = -9 and convert it to graphing form, we need to group the x's and y's together and add the right constants to each group.

Now, the equation is in the graphing form of a circle ((x-h)² + (y-k)² = r²), where (h, k) is the center and r is the radius. Hence, the circle's center is at (-3, 2) and its radius is 2.

Answer:

The value of |f(i)| is √2.

Step-by-step explanation:

The given function is

[tex]f(x)=1-x[/tex]

We need to find the value of |f(i)|.

Substitute x=i in the given function.

[tex]f(i)=1-i[/tex]

Taking modulus on both the sides.

[tex]|f(i)|=|1-i|[/tex]

Using the formula for modulus of a complex number, we get

[tex]|f(i)|=\sqrt{(1)^2+(-1)^2}[/tex]           [tex][\because |a+ib|=\sqrt{a^2+b^2}][/tex]

[tex]|f(i)|=\sqrt{1+1}[/tex]

[tex]|f(i)|=\sqrt{2}[/tex]
