Step-by-step explanation:

A median is a line segment which joins the vertex of a triangle to the midpoint of the opposite side. The median to BC is the vertex opposite it A joined to its midpoint M. The segment AM is the median.

Answer:

1. Segment AM.

Step-by-step explanation:

We have been given a triangle ABC. Points L, M and N re midpoints of the triangle. We are asked to find the median of segment BC.

We know that median of a triangle is line segment connecting the midpoint of a segment to the opposite vertex.

We can see that angle A is the opposite angle to side BC and M is the midpoint of side BC, therefore, segment AM is the median to side BC and 1st option is the correct choice.

Answer:

V_rocket  = 44[tex]\pi[/tex]  ft^3  = 138.2 ft^3

Step-by-step explanation:

Volume  of cone

V_cone = (1/3)*([tex]\pi[/tex]*(radius^2))*h

radius = 2ft

h = height of the cone = 3 ft

pi = 3.1416

V_cone = 4[tex]\pi[/tex]  ft^3

Volume cylinder

V_cylin = ([tex]\pi[/tex]*(radius^2))*h_cyl

h_cyl = height of the cylinder = 10 ft

V_cylin  = 40[tex]\pi[/tex]  ft^3

Volume rocket

V_rocket = V_cone  +  V_cylin  = 4[tex]\pi[/tex]  ft^3 + 40[tex]\pi[/tex]  ft^3

V_rocket  = 44[tex]\pi[/tex]  ft^3  = 138.2 ft^3

Answer: OPTION B.

Step-by-step explanation:

The number that are inside of the square root are called "radicands".

To subtract the expressions shown in the image attached, the radicands must be the same.

As you can see, both are equal, therefore, you can subtract the numbers that are in front of the square roots.

Then, you obtain the following result:

[tex]3\sqrt{2}-\sqrt{2}=(3-1)\sqrt{2}=2\sqrt{2}[/tex]

The answer is the option B.

Answer:

The correct answer is option B.  2√2

Step-by-step explanation:

It is given an expression, 3√2 - √2

Simplify the expression

The expression is 3√2 - √2

3√2 - √2 = √2(3 - 1)   ( taking √2 as common)

= √2 x  2

= 2√2

Therefore the simplified form of given expression(3√2 - √2) is 2√2

The correct answer is option B.  2√2

Answer:  B) The parabola is narrower.

Step-by-step explanation:

[tex]y=ax^2+bx+c[/tex] is the Standard form of a quadratic function, where a, b and c are coefficients ([tex]a\neq0[/tex]).

With the coefiicient "a" you can determine how narrow or wide the parabola is:

[tex]|a|>1[/tex] makes the parabola narrow.

[tex]0<|a|<1[/tex] makes the parabola wide.

Given the transformation of the parent function: [tex]f(x)=3x^2[/tex], you can identify that:

[tex]a=3[/tex]

Then:

[tex]|a|>1[/tex]

Therefore, as the parent function is multiplied by 3 and know [tex]|a|>1[/tex],   the parabola if narrower than the parabola of the quadratic parent function [tex]f(x)=x^2[/tex].

Answer:

Option B - The parabola is narrower.

Step-by-step explanation:

Given : The function [tex]f(x)=x^2[/tex] is transformed to  [tex]f(x)=3x^2[/tex]

To find : Which statement describes the effect(s) of the transformation on the graph of the original function?

Solution :

When the function of parabola [tex]f(x)=x^2[/tex] is transformed by 'a' unit [tex]f(x)=ax^2[/tex]

Then, [tex]|a|>1[/tex] makes the parabola narrow.

and [tex]0<|a|<1[/tex] makes the parabola wide.

On comparing with given function,

|a|=|3| >1 which is greater than 1.

Which means it makes the parabola narrow.

Therefore, the parabola is narrower.

So, Option B is correct.

The difference of two numbers is 15, and their product is 700. The numbers are 25 and 10.

The two numbers are 25 and 10.

The two numbers are 35 and 20, or -20 and -35.

The problem states that the difference of two numbers is 15, and their product is 700. Let's denote the two numbers as x and y.

We have the following system of equations:

From equation (1), we can express x in terms of y:

Substituting this into equation (2) gives:

To solve this quadratic equation, we use the quadratic formula: y = (-b ± √(b² - 4ac)) / 2a

Here, a = 1, b = 15, and c = -700. Plugging in these values, we get:

We have two solutions:

The corresponding values for x are:

Therefore, the two pairs of numbers are (35, 20) and (-20, -35).

Division! Since litres is a larger unit then millimeters, the value will need to decrease to make up for the change in units. So division is needed.

To convert milliliters to liters, use division because you're converting from a smaller to a larger unit, with 1000 milliliters equaling one liter.

To convert milliliters to liters, you would use division. This is because the process involves going from a smaller unit of measurement to a larger one, and there are 1000 milliliters in one liter. Therefore, you move the decimal point three places to the left. For example, converting 60,000 milliliters to liters, you would calculate 60,000 milliliters / 1000, resulting in 60 liters.

In solving multi-step division problems with compound units or applying compound unit multiplication in word problems, it is essential to convert all values into the same units using multiplication and division. When dealing with compound unit conversions such as milliliters to liters, division helps find the total amount or cost for a given volume in liters after initially representing values in milliliters.

Answer:

The answer is 28

Step-by-step explanation:

To find the answer, take the function and input the -5 for all x's.

f(x) = x^2 - 2x - 7

f(-5) = (-5)^2 - 2(-5) - 7

f(-5) = 25 + 10 - 7

f(-5) = 28

The value of f(-5) is 28 after plugging x = -5 in the polynomial f(x) = x² - 2x - 7

Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.

[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]

We have a polynomial:

f(x) = x² - 2x - 7

Plug x = -5

f(-5) = (-5)² - 2(-5) - 7

f(-5) = 25 + 10 - 7

f(-5) = 28

Thus, the value of f(-5) is 28 after plugging x = -5 in the polynomial f(x) = x² - 2x - 7

Answer: Hello there!

we want to find the equation that passes through the point (6, -8) (where this notation stands for (x,y)) with a slope of 0.

a linear equation has the form y = ax+ b

where a is the slope and b is the intercept.

if a = 0, our equation has the form y = b (has no dependence of x)

so we have a constant equation that passes through the point (6, -8) , this means x = 6 and y = -8, but we know that y is constant:

then y = -8 = b

so our equation is y(x) = -8

A function is a relationship between inputs where each input is related to exactly one output.

The graph in option D shows one-to-many which is not a function.

The graph in option D represents a non-functional relationship.

Option D is the correct answer

A function is a relationship between inputs where each input is related to exactly one output.

Example: f(x) = 2x is a function.

x = input

2x = output

We have,

A function can have two inputs and have the same output.

This property is called many-to-one function

For example f(x) = (-x)²,

x = 1, -1

f(1) = 1

f(-1) = 1

But a function can not have different outputs for the same inputs.

This property is called one-to-many function.

The given graph in the options are:

A - this graph represents a functional relationship.

B - this graph represents a functional relationship as many-to-one function.

C - this graph represents a functional relationship.

D - this graph represents a non-functional relationship because it is a one-to-many function

Thus,

The graph in option D shows one-to-many which is not a function.

The graph in option D represents a non-functional relationship.
