Answer:

It is given that Suria has x apples and Oranges.

Which means ,total number of fruits which includes apple and Orange is equal to x.

Suppose, number of Oranges Suria has = A

And, Number of Apples  Possessed by Suria= B

→Number of Oranges +Number of Apple=x

→ A + B =x

So,total number of apples and Oranges does Suria have altogether = x

Answer:

I got 79 degrees in my pocket, gonna solve this math problem, its just like a pick on a locket, no wonder your grades are gonna skyrocket.

Step-by-step explanation:

The number of degrees ahead of the hour hand will be 128 degrees.

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.

If the minute hand of a clock is 20 degrees behind the hour hand at this moment.

We know that the rotation of the minute hand in each minute is 6°.

The angle when minutes shows 18 minutes is given as,

⇒ 18 x 6°

⇒ 108°

The number of degrees ahead of the hour hand will be given as,

⇒ 108° + 20°

⇒ 128°

The number of degrees ahead of the hour hand will be 128 degrees.

All expressions given, A, B, C, and D, are rational numbers. This is because they all result in a number that can be expressed as the quotient of two integers when the operations are performed according to the order of operations and squared.

A rational number is a number that can be expressed as the quotient or fraction  rac{p}{q} of two integers, a numerator p and a non-zero denominator q. To determine which expression represents a rational number, we look for an outcome that is expressible as such a fraction after carrying out any operations involved in the expression.

Let's evaluate whether the expressions given result in rational numbers when the operations are performed:

Step-by-step explanation:

We are given the expression, [tex]\frac{1}{x-1}-\frac{3}{x^{2}+2x-3}[/tex].

So, upon simplifying the expression, we get,

[tex]\frac{1}{x-1}-\frac{3}{x^{2}+2x-3}[/tex]

implies [tex]\frac{1}{x-1}-\frac{3}{(x-1)(x+3)}[/tex]

i.e. [tex]\frac{1(x+3)-3}{(x-1)(x+3)}[/tex]

i.e. [tex]\frac{x+3-3}{(x-1)(x+3)}[/tex]

i.e. [tex]\frac{x}{(x-1)(x+3)}[/tex]

So, from the options, we see that,

Steve has correctly subtracted the rational expressions.

Thus, option A is correct.

We are given this equation

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

The vertex form is given by:

[tex] y=a(x-h)^{2} +k [/tex]

Now let us try to convert our equation into vertex form:

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

Vertex form is given by:

[tex] y=-2(x-0.5)^{2} +2.5 [/tex]

comparing our equation with vertex form ,

The vertex (h,k) is (0.5, 2.5)

Next we have to find y when x=6, plugging x as 6 in the given equation,

[tex] y=-2(6)^{2} +2(6)+2 [/tex]

y=-58

So at x=6, y=-58.

Final answer:

The probability that the five horses finish first through fifth in any order is 0.0004995 or 0.04995%.

Explanation:

The probability that the five horses owned by one person finish first through fifth, regardless of order, in a horse race with 14 entries can be calculated using combinatorics. First, we determine the number of ways to choose 5 horses out of 14 to finish in the top 5 positions, which is C(14,5). Then we calculate the number of favorable outcomes, which, since the order doesn't matter for the set of horses owned by the person, is just 1. To find the probability, we divide the number of favorable outcomes by the total number of possible outcomes, resulting in 1/C(14,5). Using the formula for combinations C(n,r) = n! / (r! * (n-r)!), where n is the total number of entries and r is the number of horses owned by the person, we can calculate the exact probability.

The formula gives us C(14,5) = 14! / (5! * (14-5)!) = 14! / (5! * 9!) = 2002. Therefore, the probability is 1/2002, which simplifies to 0.0004995 or 0.04995%.

Answer:

[tex]3^{\circ}[/tex]

Step-by-step explanation:

Let x represent the angle of elevation.

We have been given that Jamison takes a 20 foot board and props it up with a one foot block at the far end to make a daredevil jump ramp for his bike.

Upon looking at our attached file, we can see that 20 feet board and 1 foot board forms a right triangle with respect to ground, where side of 1 foot is opposite side and 20 feet side is hypotenuse.

We know that sine relates the opposite side of right triangle to its hypotenuse, so we can set an equation as:

[tex]\text{sin}=\frac{\text{Opposite}}{\text{Hypotenuse}}[/tex]

[tex]\text{sin}(x)=\frac{1}{20}[/tex]

Using arcsin we will get,

[tex]x=\text{sin}^{-1}(\frac{1}{20})[/tex]

[tex]x=2.865983982599^{\circ}[/tex]

Upon rounding our answer to nearest degree we will get,

[tex]x\approx 3^{\circ}[/tex]

Therefore, the measure of the angle of elevation of the ramp is 3 degrees.

Final answer:

To maximize the product of two numbers with a fixed sum of 156, we set up an equation for the product, differentiate, and find that the maximum product is obtained when both numbers are 78.

Explanation:

To find two positive real numbers whose product is a maximum and whose sum is 156, we need to use the concept of optimization in calculus. This involves taking the derivative of the function representing the product of the two numbers and setting it equal to zero to find the critical points. Since the sum of the numbers is fixed at 156, we can express one number in terms of the other, for example, x and 156 - x. The product of these two numbers is x(156 - x). To find the maximum product, we differentiate this function with respect to x:

[tex]\frac{d}{dx} [x(156 - x)] = 156 - 2x[/tex]

Setting this derivative equal to zero gives us 156 - 2x = 0, solving for x we find-

x = 78.

This gives us the two numbers as 78 and 78, because the sum must be 156 and the other number would be 156 - 78. To confirm that this gives a maximum, we would test the second derivative or use the first derivative test. However, by symmetry, when the sum of two numbers is fixed, their product is maximized when the two numbers are equal. In this case, both numbers are 78.

 1.1      Factoring:  x2-15 

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =
         A2 - AB + BA - B2 =
         A2 - AB + AB - B2 = 
         A2 - B2

Note :  AB = BA is the commutative property of multiplication. 

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check : 15 is not a square !! 

Ruling : Binomial can not be factored as the difference of two perfect squares.

 2.1      Solve  :    x2-15 = 0 

 Add  15  to both sides of the equation : 
                      x2 = 15 
 
 When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get:  
                      x  =  ± √ 15  

 The equation has two real solutions  
 These solutions are  x = ± √15 = ± 3.8730  
 

Final answer:

Explaining the number of real number solutions for the given quadratic equation x²-15=0.

Explanation:

x²-15=0

To find the number of real number solutions for the equation, we start by setting the expression to zero:

x² - 15 = 0

x² = 15

x = ±√15

Therefore, the equation has two real number solutions, which are ±√15.

Answer: b. -3 or 2

Step-by-step explanation:

All linear function has a constant slope and degree as 1.

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant slope.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

Linear functions are lines in the coordinate and describe itself that the slope will be the same irrespective of the point.

A linear function is given by ;

y = mx  + x where m is slope.

As we can see the degree of x and y both are 1 so the linear function has a degree of 1.

Hence "All linear function has a constant slope and degree as 1".
