Answer:

There are 24 outcomes in the sample space.

Step-by-step explanation:

Suppose that we have some events, such that each one of these events has a given number of outcomes.

If we have an experiment where we perform all of these events, the total number of possible outcomes is equal to the product between the number of outcomes for each one of the events.

Let's apply this to our case.

Here we have two events:

Rolling a standard number cube: 6 outcomes

Spinning a spinner with 4 equal sections: there are 4 outcomes.

Then the total number of outcomes in the sample space is the product:

C = 6*4 = 24 outcomes.

There are 24 outcomes in the sample space.

Answer:

The answer is 34.5cm2. (don't blame meh if wrong)

Step-by-step explanation:

Step 1: Find the area of the square; 4.6 x 3.2 = 14.72

Step 2: Find the bottom length to find the area of the triangle; 7.5 - 3.2 = 4.3

Step 3: Find the area of the triangle; 4.3 x 4.6 = 19.78

Step 4: Add the area of the square to the area of the triangle; 14.72 + 19.78 = 34.5

Answer:

angle E is 15 dgeree

Step-by-step explanation:

hypotenuse is the side opposite to 90 degree. So, here hypotenuse is DE.

take angle E as reference angle .Then,

opposite=DF = 23 feet

hypotenuse=DE = 90 feet

using sin rule

sin E =opposite/hypotenuse

sin E=23/90

sin E=0.255

E = [tex]sin^{-1} (0.255)[/tex]

E=14.77

E=15 degree

Step-by-step explanation:

A circle equation is represented by

[tex]x {}^{2} + {y}^{2} = r {}^{2} [/tex]

A circle have both terms to the 2nd. degree

The 1st equation, 2nd equation, 4th equation are circles.

A quadratic is represented by

[tex] {x}^{2} + bx + c[/tex]

A quadratic equation only has one term that is second degree.( meaning if x and y are both to the 2nd degree, it will not be a quadratic, it will be a circle.

The 3rd equation is a quadratic.

The fifth equation has a leading coefficient at the degree of 1 so it is other(linear)

This language derives from the area of a square being its side length multiplied by itself. The word "quadratic" comes from quadratum, the Latin word for square.

f(x) = ax2 + bx + c, where a, b, and c are numbers and an is not equal to zero, is a quadratic function. A parabola is the shape of a quadratic function's graph. Although the "width" or "steepness" of a parabola can vary as well as its direction of opening, they all share the same fundamental "U" form.

From the given table we can get the dy/dx which is the slope (m) ,

Therefore,

dy/dx = (7 - 10 ) / ( 4 - 3 )

dy/dx = -3

Now,

( y - y1 ) = m ( x - x1 )

Putting the value from the table,

( y - 10 )  = -3 ( x -5 )

=> y - 10 = -3x + 15

=> 3x + y = 25

Answer:

C and D

Step-by-step explanation:

Answer:

You did not include the graphs, but I can explain how the graph is and so you can recognize it.

1) for x = 0, y = sin(0) = 0, so the  origin (0,0) is part of the graph.

2) The range of the function is the interval [-1, 1]. This is, y is from -1 to 1, and the graph oscilates (is a wave) between those minimum and maximum.

3) The periodicity, P, of the function is such that 0.5P = 2π = > P = 4π

That means that the values repeat every 4π interval (which is the same that 720°)

4) The zeroes of the function are 2π * n, where n is any whole number (negative, zero or positive).

That means that the function crosses the x-axis at

..., -6π, -4π, 2π, 0, 2π, 4π , 6π, ...

5) It is an odd function (which means that f(x) = sin(0.5x) = - f(-x) = - sin(-0.5x).

Now you have plenty information to identify the graph.

I also include a graph of the function in the attached pdf file.

Answer:

b) ∛7

Step-by-step explanation:

If p= 2q^3 - 1, what is the value of q when p is 13

Hence:

13 = 2q³ - 1

We add 1 to both sides

13 + 1 = 2q³ - 1 + 1

14 = 2q³

We divide both sides by 2

14/2 = 2q³/2

7 = q³

q³ = 7

We take the cube root of both sides

∛q³ = ∛7

q = ∛7

Option b is the correct option

Answer:

a) The equation for the situation = 14.50 = 4.5 + 1.25n

b) The number of oranges she bought = 8 oranges

Step-by-step explanation:

Where n represents the number of oranges.

The equation is written as

Total charge = $0.75 × 6 + $1.25 × n

$14.50 = $0.75 × 6 + $1.25 × n

14.50 = 4.5 + 1.25n

1.25n = 14.5 - 4.5

1.25n = 10

n = 10 / 1.25

n = 8 oranges

Answer:

d

Step-by-step explanation:

3 shirts that each costs s dollars would be 3s

jeans is $30, pair of shoes is $50, add $30+$50 and you'll end up with $80

so, an expression in the simplest form that represents the total cost would be:

d. 3s+80

The expression in simplest form that represents the total amount is option d. 3s+80.

In order to understand why this is the correct expression, let us break down the given information step-by-step:

1. You buy 3 shirts that each cost s dollars. This implies that since you are buying 3 shirts, the cost of the shirts is 3s dollars.

2. You also buy a pair of shoes for $50. So, the cost of the shoes is $50.

3. Additionally, you buy jeans for $30.

To find the total amount, we need to add up the cost of the shirts, shoes, and jeans together.

The cost of the shirts is 3s dollars.
The cost of the shoes is $50.
The cost of the jeans is $30.

The cost of the shirts (3s) plus the cost of the shoes ($50) plus the cost of the jeans ($30) is: 3s + $50 + $30.
Therefore, the total amount is 3s + $50 + $30.

Since $50 and $30 are constant values, simplifying the expression further yields: 3s + 80.

Hence, the correct expression in simplest form that represents the total amount is option d. 3s + 80.

Answer: The value of 'x' is -1.8 where the given equation approximately equal

Step-by-step explanation:

It is given that the value of 'x' lies in the range of -2 to -1.5 and we need to find out the value of 'x' where both the equations become equal

Given set of equations:

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

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

Plugging value of 'y' from equation 2 to equation 1:

[tex]x^2+2=\frac{1}{(x+2)}\\\\x^2+2(x+2)=1\\\\x^3+2x^2+2x+4=1\\\\x^3+2x^2+2x+3=0[/tex]

On solving, the real root comes out to be, x = -1.8

Hence, the value of 'x' is -1.8 where the given equation approximately equal

Answer:

C and D

Step-by-step explanation:

Mathematically, a unit circle is one in which the value of the radius is 1 unit

Generally, for a unit circle we have it that;

r^2 = x^2 + y^2

where (x,y) represents the coordinates of a point on the unit circle

But from above, r = 1

Thus:

x^2 + y^2 = 1

Looking at option C, by squaring each coordinate, we have

(6/7)^2 = 36/49 and the second as 13/49

by adding both, we have

36/49 + 13/49 = 49/49 = 1

Thus, we have this as a coordinate on the unit circle

For the last option;

(5/13)^2 = 25/169 and (12/13)^2 = 144/169

Adding both, we have;

25/169 + 144/169 = 169/169 = 1

So this is also a point on the unit circle
