Answer:

60y = 30x - 12

y = 1/2x - 1/5

The slope is 1/2

Answer:

1/2

Step-by-step explanation:

30 over 60 is half

Answer:

If x varies directly as y, then x=ky. y=5 and x=2.5 are substituted into x=ky to find k.

2.5=5k

k=2.5/5

k=5.

K =5 is substituted in x=ky to find y where x is 10.

x=5y

10=5y

y=10/2

y=2

Answer:  The required value of y is 20.

Step-by-step explanation:  Given that y is 5 when x is 2.5 and y varies directly with x.

We are to find the value of y when x is 10.

According to the given information, we can write

[tex]y\propto x\\\\\Rightarrow y=kx~~~~~~~~~~[\textup{where k is the constant of proportionality}][/tex]

When y = 5 and x = 2.5, then we have

[tex]5=k\times2.5\\\\\Rightarrow k=\dfrac{5}{2.5}\\\\\Rightarrow k=2.[/tex]

So, we get

[tex]y=2x.[/tex]

Therefore, when x = 10, then the value of y is

[tex]y=2\times10=20.[/tex]

Thus, the required value of y is 20.

Answer: The 9th term is 6561

Step-by-step explanation:

The geometric sequences have the following formula

[tex]a_n = a_1(r)^{n-1}[/tex]

Where [tex]a_1[/tex] is the first term of the sequence and r is the common ratio between the consecutive terms of the sequence

In this case the sequence is   1 -3 9 -27

So [tex]a_1 = 1[/tex]

Observe that the common ratio  r is:

[tex]r=\frac{-3}{1}=\frac{9}{3}=\frac{-27}{9}=-3[/tex]

So the formula is:

[tex]a_n = (-3)^{n-1}[/tex]

We want to find [tex]a_9[/tex]

[tex]a_9 = (-3)^{9-1}[/tex]

[tex]a_9 = (-3)^{8}=6561[/tex]

Answer:

D

Step-by-step explanation:

By definition for a right triangle with sides a, b, c, where c is the hypotenuse,

the following must be true:

a² + b² = c²

By using this formula on all the choices, we find that only D satisfies this formula

i.e.

for

a = √35 --------> a² = 35

b = √14 --------->b² = 14

c = 7 ------> c² = 49

a² + b² = 35 + 14 = 49 which is equal to the value of c² above

The correct answer is √35 , √14 , 7

Pythagoras' theorem that the square of a right triangle's hypotenuse is equal to the sum of the squares of the other two sides.

p^2 + b^2 = h^2 ( In a right angled triangle)

p = perpendicular of the triangle

b = base of the triangle

h = hypotenuse of the triangle

According to the Pythagoras theorem:

p^2 + b^2 = h^2 (In a right angled triangle)

In Option D

(√35)^2 + (√14)^2 = 7^2

49 = 49

Pythagoras theorem is followed in this triangle, hence it is a right angled triangle.

Answer:

See attachment.

If altitude = 45 then

side = 2 * height (or altitude) / square root of 3

side = 2 * 45 / 1.7320508076

side = 90 / 1.7320508076

side = 51.9615242271

Step-by-step explanation:

Follow below steps;

When dealing with an equilateral triangle, dividing it by an altitude creates two 30-60-90 right triangles. Since we know the length of the altitude (45), which corresponds to the shorter leg in the 30-60-90 triangle, we can find the length of the side of the equilateral triangle (which is the hypotenuse of the 30-60-90 triangle) using the properties of this special right triangle.

To begin, we recognize that the ratios of the sides of a 30-60-90 triangle are 1:\\(extbackslashsqrt{3}\\):2. Thus, if the shorter leg is 45, the hypotenuse will be twice that length, because the ratio of the shorter leg to the hypotenuse is 1:2. Therefore, the length of a side of the equilateral triangle is 45 * 2, which equals 90.

Answer:

see explanation

Step-by-step explanation:

Given

2x² + 9x + 10 = 0

To factor the quadratic

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 2 × 10 = 20 and sum = + 9

The factors are + 4 and + 5

Use these factors to split the x- term

2x² + 4x + 5x + 10 = 0 ( factor the first/second and third/fourth terms )

2x(x + 2) + 5(x + 2) = 0 ← factor out (x + 2) from each term

(x + 2)(2x + 5) = 0

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

2x + 5 = 0 ⇒ 2x = - 5 ⇒ x = - [tex]\frac{5}{2}[/tex]

Answer:

1. x = 2

2. x = - 5/2

Step-by-step explanation:  First put parenthesis around the equation

( 2x^2 + 4x ) + ( 5x + 10) = 0

2x ( x+ 2) 5 (x + 2),

when you have the same answer inside the parenthesis you know your right.

Answer:

$324.19

Step-by-step explanation:

First, find the price when marked down. Multiply 475 with 0.35:

475 x 0.35 = 166.25

Subtract 166.25 from the total cost:

475 - 166.25 = 308.75

Now, solve for the tax. Tax is 5% (0.05). Multiply 0.05 with the new cost:

308.75 x 0.05 = ~$15.44

Add 15.44 to the sales price:

308.75 + 15.44 = $324.19

$324.19 is your answer.

Answer:

The set {10 , 24 , 26} formed a right triangle

Step-by-step explanation:

* Lets explain how to check the sides lengths which formed a  

 right triangle

- In triangle ABC

# If AC is the longest side in length

# If (AC)² = (AB)² + (BC)²

∴ AB , BC , AC formed a right angle triangle  

∴ m∠B = 90°  (The angle opposite to the longest side)

∴ AC is the hypotenuse

* Now lets solve the problem

- In set 8 , 12 , 15

∵ The longest side is 15 cm

∴ (15)² = 225

∵ (8)² + (12)² = 64 + 144 = 208

∵ (15)² ≠ (8)² + (12)²

∴ The set not formed a right triangle

- In set 10 , 24 , 26

∵ The longest side is 26 cm

∴ (26)² = 676

∵ (10)² + (24)² = 100 + 576 = 676

∵ (26)² = (10)² + (24)²

∴ The set formed a right triangle

- In set 12 , 20 , 25

∵ The longest side is 25 cm

∴ (25)² = 625

∵ (12)² + (20)² = 144 + 400 = 544

∵ (25)² ≠ (12)² + (20)²

∴ The set not formed a right triangle

- In set 15 , 18 , 20

∵ The longest side is 20 cm

∴ (20)² = 400

∵ (15)² + (18)² = 225 + 324 = 549

∵ (20)² ≠ (15)² + (18)²

∴ The set not formed a right triangle

* The set {10 , 24 , 26} formed a right triangle

Answer:

(5,-1)

Step-by-step explanation:

4x+3y=17

3x+2y=13

So elimination sounds fun but we will have to do manipulation:

Multiply top equation by 2 and bottom equation by 3. This will cause the second term in both by 6y which means we would be setup for elimination.

8x+6y=34

9x+6y=39

--------------------now subtract the equations

-x+0=-5

So x=5

Now plug it into either question (no matter which-pick and choose)

I will go with the second original 3x+2y=13

So if x=5 we have 15+2y=13

Subtract 15 on both sides:        2y=-2

Now divide both sides by 2:      y=-1

Answer (5,-1)

Final answer:

To solve the simultaneous linear equations 4x + 3y = 17 and 3x + 2y = 13, the elimination method shows that the solution is x = 5 and y = -1.

Explanation:

To solve the simultaneous linear equations 4x + 3y = 17 and 3x + 2y = 13, one could use either the substitution method, the elimination method, or matrix methods. However, as per the guidance, we will follow the elimination method which is efficient and easily understandable.'

Let's multiply the first equation by 2 and the second equation by 3, which will give us:

8x + 6y = 34 (equation 1 multiplied by 2)

9x + 6y = 39 (equation 2 multiplied by 3)

Now, subtract the first new equation from the second new equation to eliminate y:

9x - 8x + 6y - 6y = 39 - 34

x = 5

Substitute x = 5 into one of the original equations to find y. For example, put x = 5 in 4x + 3y = 17:

4(5) + 3y = 17

20 + 3y = 17

3y = -3

y = -1

Therefore, the solution to the system of equations is x = 5 and y = -1.

Step-by-step explanation:

Answer:

B. [tex]18x^{2} y^{2} \sqrt[3]{3xy^{2} }[/tex]

Step-by-step explanation:

To simplify this expression, use the fact that the root of a number (in this case is the cube root)  can be expressed like a fractional exponent (1/3). Using this, the expression changes to:

[tex]3x(648x^{4}y^{8})^{(1/3)}[/tex]

Next step is to put the exponent inside the parenthesis:

[tex]3x(648^{1/3}x^{4/3}y^{8/3})[/tex]

Find the prime factorization  of 648:

648 =3⋅3⋅3⋅3⋅2⋅2⋅2

648=3⁴∗2³

[tex]3x(3^{(4/3)}2^{(3/3)}x^{4/3}y^{8/3})[/tex]

Change all improper fractions in exponent to mixed fractions

[tex]3x(3^{1(1/3)}2^{1}x^{1(1/3)}y^{2(2/3)})[/tex]

Separate integers exponents from fractional:

[tex]3x(3\cdot3^{(1/3)}\cdot 2 \cdot x\cdot x^{1/3}\cdot y^{2}\cdot y^{2/3})[/tex]

Re-arrange (all numbers with fractional exponents must be together):

[tex]3x(3 \cdot 2\cdot x\cdot y^{2}\cdot 3^{(1/3)}x^{1/3}y^{2/3})[/tex]

Multiply the 3x with the numbers that have an integer exponent:

[tex]18x^{2}y^{2}(3^{(1/3)}x^{1/3}y^{2/3})[/tex]

Take out  the exponent 1/3 from the parenthesis:

[tex]18x^{2}y^{2}(3xy^{2})^{1/3}[/tex]

And change the representation of the root to use a radical symbol

[tex]18x^{2} y^{2} \sqrt[3]{3xy^{2} }[/tex]

Step-by-step explanation:

The ratio is the same each time (2/3), so this can be modeled as a geometric sequence.

an = a₁ (r)^(n-1)

where an is the nth term, a₁ is the first term, and r is the common ratio.

On the first rebound, the ball rises to 2/3 × 2 = 4/3, so a₁ = 4/3.

an = 4/3 (2/3)^(n-1)

On the sixth rebound, the ball rises to:

a₆ = 4/3 (2/3)^(6-1)

a₆ = 4/3 (32/243)

a₆ = 128/729

a₆ ≈ 0.176

3x +11 = K

To solve for X, we need to isolate x on one side.

Answer: We want to know f( g (13) ), here g(13) is just a number, so you are evaluating f in a number, first we need to know the value of g(13). Looking in the diagram you can see that g(13) = 16.

So f(g(13)) = f(16)

Also, looking in the diagram you can see that f(16) = 32

So, f ( g (32) ) = 32

Answer:

The direction of 5c + 4d is approximately 19.0° clockwise with

the positive part of x-axis

Step-by-step explanation:

* Lets talk about the direction of a vector

- If the vector is (x , y), then  

# Its magnitude is √(x² + y²)

# Its direction is tan^-1 (y/x)

- The direction is the angle between the positive part of x-axis and  

  the vector

* Lets solve the problem

∵ c = (2.4 , 0.45) and d = (7 , -4)

- To find 5c + 4d , multiply the two coordinates of c by 5 and the two

  coordinates of d by 4

# Multiply c by 5

∴ 5c = [5(2.4) , 5(0.45)]

∴ 5c = (12 , 2.25)

# Multiply d by 4

∴ 4d = [4(7) , 4(-4)]

∴ 4d = (28 , -16)

- Lets add 5c and 4d

∴ 5c + 4d = (12 , 2.25) + (28 , -16)  

∴ 5c + 4d = [(12 + 28) , (2.25 + -16)]

∴ 5c + 4d = (40 , -13.75)

- The vector is in the 4th quadrant because the x-coordinate is

 positive and the y-coordinate is negative

* Find the direction of 5c + 4d

∵ The direction is tan^-1 (y/x)

∴ The direction is tan^-1 (-13.75/40) = -18.97°

* The direction of 5c + 4d is approximately 19.0° clockwise with

 the positive part of x-axis

ANSWER

C. (0,4)

EXPLANATION

The given graph has equation:

[tex]y = 4( {3}^{x} )[/tex]

The y-intercept is where the graph touches the y-axis.

At this point the value of x is zero.

We substitute x=0 into the equation to obtain:

[tex]y = 4( {3}^{0} )[/tex]

Recall that any non-zero number exponent zero is 1.

This implies that,

[tex]y = 4( 1 ) = 4[/tex]

Hence the y-intercept is (0,4)
