Answer:

x≈47.4

Step-by-step explanation:

Use sine, since the triangle is a right triangle and doesn't have any special properties.

sin28=x/101

101*sin28=x

solving this, you get that x≈47.4.

The ratio of the amount of milk Mia had to the amount of milk Dante had at first = 4 : 5

"It is the comparison of two quantities of the same kind."

"It is a mathematical statement which consists of equal symbol between two mathematical statements."

For given question,

Let 'x' be the initial amount of milk Mia had and 'y' be the initial amount of milk Dante had.

After Mia gave 1/4 of her milk to Dante, Dante had twice the amount of milk as Mia.

We write above statement inn equation form as,

[tex]2(\frac{3}{4} x)=(y+\frac{1}{4} x)[/tex]

We simplify above equation to find the ratio of the amount of milk Mia had to the amount of milk Dante had at first.

[tex]\Rightarrow 2(\frac{3}{4} x)=(y+\frac{1}{4} x)\\\\\Rightarrow \frac{6}{4}x- \frac{1}{4} x=y\\\\\Rightarrow \frac{5}{4}x=y\\\\ \Rightarrow \frac{x}{y} =\frac{4}{5}\\\\ \Rightarrow x:y=4:5[/tex]

Therefore, the ratio of the amount of milk Mia had to the amount of milk Dante had at first = 4 : 5

Answer:

Option (3).

Step-by-step explanation:

Attached figure is the graph of a function,

f(x) = -[tex]\sqrt{-x}[/tex]

Since domain of any function is the set of all possible input values of the function,

Therefore, Domain of the function is,

Domain : x ≤ 0 Or (-∞, 0]

And range of the function is the set of all possible output values (y-values) of the function.

Therefore, Range of the function will be,

Range : y ≤ 0 Or (-∞, 0]

Therefore, Domain and range of this function is same.

Option (3) will be the answer.

In the triangle NRL,

Points P, S and M are the midpoints of the sides NR, RL and LN respectively.

Sides SM = (3x - 4), NR = (9x - 20)

By the theorem of midpoints in a triangle,

SM = [tex]\frac{1}{2}\text{NR}[/tex]

(3x - 4) = [tex]\frac{1}{2}(9x-20)[/tex]

6x - 8 = 9x - 20

9x - 6x = 20 - 8

3x = 12

x = 4

Therefore, Option (A) will be the answer.

The value of x is equal t 4

Data;

The midpoint of a line is half the distance of the line.

Since the length of the line is RN and midpoint of the line is SM.

[tex]SM = \frac{1}{2} RN[/tex]

Let's substitute the values into the equation

[tex]SM = \frac{1}{2} NR\\3x - 4 = \frac{1}{2}(9x- 20)\\ 3x - 4 = \frac{1}{2} (9x - 20)\\2(3x - 4) = 9x - 20\\6x - 8 = 9x - 20\\9x-6x = 20 - 8 \\3x = 12\\\frac{3x}{3} = \frac{12}{3} \\x = 4[/tex]

[tex](x+4)^2+(y+6)^2=100[/tex]

Step-by-step explanation:

Given a circle centred at the point P(-4,-6) and passing through the point

R(2,2).

To find its equation, we follow these steps.

Step 1: Determine its radius, r using the distance formula

For point P(-4,-6) and R(2,2)

[tex]\text{Distance Formula=}\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\\text{Radius=}\sqrt{(2-(-4))^2+(2-(-6))^2} \\=\sqrt{(2+4))^2+(2+6)^2}\\=\sqrt{6^2+8^2}\\=\sqrt{100}\\Radius=10[/tex]

Step 2: Determine the equation

The general form of the equation of a circle passing through point (h,k) with a radius of r is given as: [tex](x-h)^2+(y-k)^2=r^2[/tex]

Centre,(h,k)=P(-4,-6)

r=10

Therefore, the equation of the circle is:

[tex](x-(-4))^2+(y-(-6))^2=10^2\\\\(x+4)^2+(y+6)^2=100[/tex]

The trigonometry expression sin 49° is written in the form of cosine will be cos 41°.

Trigonometric functions examine the interaction between the dimensions and angles of a triangular form.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The trigonometry expression is given below.

⇒ sin 49°

We know that sin (90 - A) = cos A. Then the expression is also written as,

⇒ sin 49°

⇒ sin (90° - 41°)

⇒ cos 41°

The trigonometry expression sin 49° is written in the form of cosine will be cos 41°.

Answer: C. It is the graph of f(x) shrunk horizontally by a factor of 6.

Step-by-step explanation:

When we multiply a function’s input by a positive constant, we get a function whose graph is stretched or compressed horizontally in relation to the graph of the original function. If the constant is between 0 and 1, we get a horizontal stretch; if the constant is greater than 1, we get a horizontal compression of the function.
