Answer: C) 6.0025

Step-by-step explanation:

The equation for the area of a circle requires the radius, you put in the full diameter. Just divide 4.9 by 2, which gives you 2.45. 2.45 squared is equal to 6.0025 and then slap your pi on to the end of it.

Answer:

[tex]6.0025\pi \: {m}^{2} [/tex]

Step-by-step explanation:

The formula for the area of a circle:

[tex]\pi \times {r}^{2} [/tex]

We are given the diameter of the circle, which is two times its radius. To find the radius, we divide the diameter by 2.

4.9 ÷ 2 = 2.45 m^2.

Now we need to square the radius:

[tex] {2.45}^{2} = 6.0025[/tex]

So, the area in terms of pi would be

[tex]\pi \ \times {6.0025}^{2} \: {m}^{2} [/tex]

Or

[tex]6.0025 \times \pi \: {m}^{2} [/tex]

The slope is given as 1.

The Y-intercept is where the line crosses the Y axis when X is 0. This is also given by the point (0,5/6). X is 0 and Y is 5/6, so the Y-intercept is 5/6.

The equation of a line is given as y = mx +b where m is the slope and b is the y-intercept.

The equation is: y = x +5/6

Answer:

y = x+5/6

Step-by-step explanation:

The slope intercept form of the equation of a line is

y = mx +b

We are given the slope of 1 and the y intercept of 5/6 (The y intercept is when x=0)

y = 1x+5/6

y = x+5/6

Answer:

Theoretical  P(3) = 1/6

Experimental P(3) = 67/450

Step-by-step explanation:

A die has 6 possibilities that can come up {1,2,3,4,5,6}  They are all equally likely, so each has a probability of 1/6

a  P(getting a 3) = 1/6

We rolled a 3 67 times out of 450.  This is our experimental probability

b P (getting a 3) = 67/450

This does not simplify

As your math teacher, let's solve this problem together step by step.

a. Theoretical Probability of Rolling a 3:
A standard number cube, often referred to as a die, has six faces numbered 1 through 6. Since all faces are usually designed to be equally probable, the theoretical probability of rolling a three (or any specific number) is the ratio of the number of successful outcomes (rolling a 3) to the total number of possible outcomes (any number from 1 to 6).

So,

Theoretical Probability = Number of successful outcomes / Total number of possible outcomes
                       = 1 / 6

This is already in the simplest form since 1 and 6 have no common divisors other than 1.

b. Experimental Probability of Rolling a 3:
The experimental probability, in contrast to the theoretical probability, is determined based on actual trials or experiments. In this case, the cube was rolled 450 times, and the number 3 appeared 67 times.

So,

Experimental Probability = Number of times a 3 was rolled / Total number of rolls
                        = 67 / 450

Now, to simplify the fraction, you would find the greatest common divisor (GCD) of 67 and 450 and divide both numerator and denominator by that GCD.

Looking at the numbers, they do not immediately suggest a common factor, and since 67 is a prime number, we can reasonably conclude that the fraction is already in its simplest form. Therefore, the experimental probability is:

                        = 67 / 450

So there you have it, answers to both questions in their simplest form:

a. The theoretical probability of rolling a 3 on a number cube is 1/6.
b. The experimental probability of rolling a 3 given the cube is rolled 450 times and 3 comes up 67 times is 67/450.

Answer:65

Step-by-step explanation:

The triangle is isosceles triangle and the base angles must be the same

The measure of angle z is 65°.

Given that, in ΔXYZ XZ=XY=7 cm.

We need to find the value of ∠Z.

In an isosceles triangle with two equal sides. The angles opposite the equal sides are also equal.

Since XZ=XY=7 cm.

Here, ∠Y=∠Z=65°

Therefore, the measure of angle z is 65°.

outer  2x*1 = 2x

Answer:

x = 9

Step-by-step explanation:

Use the equation of the line, and let y = 0. Then solve for x.

y = 2/3 x - 6

Let y = 0:

0 = 2/3 x - 6

Add 6 to both sides.

6 = 2/3 x

Multiply both sides by 3/2.

3/2 * 6 = x

x = 9

Since f(d) and g(d) represent two types of discounts that you will receive off of the price, the composite function is f(g(d)) = 0.8d - 15.

In Mathematics and Geometry, a function composition is an operation (∘) that combines two functions f(x) and g(x), in order to produce a composite function h(x) = (g∘f)(x), such that h(x) = g.

In this exercise, we would determine the corresponding output values for the composite functions by using the substitution method as follows;

f(g(d)) = 0.8d - 15

In this context, we can reasonably infer and logically deduce that the composite function is f(g(d)) = 0.8d - 15.

Yes, the given equation is also a function. (it's a quadratic function)

We know a function exists when there is only one value of y (output) for each x (input).

We can easily know if an equation (relation) is also a function using the graphic method:

To know if a relation is a function, we need to graph it a draw a vertical line, if the line cut the graph in only one point, the relation is a function, otherwise, if the vertical line cuts the graph in two or more points, the relation is a not a function. Remember, the condition for a function is that there is only one output for each input.

D.) x^2-3x-5

Step-by-step explanation:

f(x)=3x+5

g(x)=x^2 .

Find g(x)-f(x)

g(x) - f(x)=  x^2 -(3x+5)

Distribute the minus sign        

 x^2 -3x-5

Answer:

x² - 3x - 5 ⇒ answer D

Step-by-step explanation:

* Lets explain how to solve the problem

- There are two functions f(x) ang g(x)

- f(x) = 3x + 5 ⇒ it is a linear function

- g(x) = x² ⇒ it is a quadratic function

- Both functions have a domain the set of real numbers

- We want to subtract f(x) from g(x)

* Lets solve the problem

∵ g(x) = x²

∵ f(x) = 3x + 5

∵ f(x) will subtracted from g(x)

∴ g(x) - f(x) = (g - f)(x)

- Lets make the subtraction

∴ (g - f)(x) = x² - (3x + 5)

- Open the bracket by multiply the negative sign by the two terms

 of the bracket

∵ -(3x) = - 3x

∵ -(5) = - 5

∴ (g - f)(x) = x² - 3x - 5

∴ g(x) - f(x) = x² - 3x - 5

Numbers' absolute values are outputted as non-negative numbers. The arrangement of given numbers from least to greatest is: Option A: -4, -2, 3, |5|, |-6|

Modulus of a real number, also called absolute value, is non-negative result of the input value.

This is defined as:

[tex]|x| = x ; \text{ (x is non-negative)}\\\\|x| = -x ; \text{ (x is negative)}[/tex](so that the outer negative makes the negative number positive).

Example:

[tex]|5| = 5\\|-5| = -(-5) = 5[/tex]

A number has both magnitude(its absolute value) and its sign(positive or negative).

If numbers are negative, the more their magnitude increases, the lesser they become.

If numbers are positive, the more their magnitude increases, the greater they become.

Thus, for -5, the magnitude is 5, and sign is –ve.

Also, positive numbers > 0 > negative numbers.
