Answer:363

Step-by-step explanation:

We have to find partial sum for the sequence 243 , 81 , 27 ..... up to 5 terms(S5 given)

The sequence actually is 3^5,3^4.,3^3.....

Therefore first 5 terms are 1) 3^5 I.e. 243

2) 3^4 I.e. 81

3) 3^3 I.e. 27

4)) 3^2 I.e. 9

5) 3^1 I.e. 3

Adding all those no. we get partial sum of first 5 no. of the sequence

So, 243 + 81 + 27 + 9 + 3

= 363

Hope it helps!!!

Look at the picture.

∠2 and ∠3 are Corresponding Angles. j || k, thereofre m∠2 = m∠3.

∠1 and ∠3 are supplementary angles, therefore m∠1 + m∠3 = 108°.

m∠1 = 10x + 4, m∠2 = m∠3 = 4x - 6. Therefore we have the equation:

(10x + 4) + (4x - 6) = 180

(10x + 4x) + (4 - 6) = 180

14x - 2 = 180     add 2 to both sides

14x = 182     divide both sides by 14

x = 13

10x + 4 = 10(13) + 4 = 130 + 4 = 134

4x - 6 = 4(13) - 6 = 52 - 6 = 46

Answer:

A. 8x - 9y = -23

Step-by-step explanation:

(-4,-1) and (1/2,3)

We write the equation in slope intercept form y=mx+b

then we convert it into standard form

m is the slope and b is the y intercept

[tex]slope = \frac{y_2-y_1}{x_2-x_1}[/tex]

(-4,-1) and (1/2,3)

[tex]slope = \frac{3-(-1)}{\frac{1}{2}-(-4)}[/tex]

[tex]slope = \frac{4}{\frac{1}{2}+4}[/tex]

[tex]slope = \frac{4}{\frac{9}{2}}[/tex]

[tex]slope = 4*\frac{2}{9}[/tex]

[tex]slope m =\frac{8}{9}[/tex]

To find out b we plug in (-4,-1)  and slope m value in y = mx+b

-1 = (8/9) (-4) + b

[tex]-1 = -\frac{32}{9} +b[/tex]

Add 32/9 on both sides

[tex]-1+\frac{32}{9} = b[/tex]

Take common denominator 9

[tex]\frac{-9+32}{9} = b[/tex]

[tex]\frac{23}{9} = b[/tex]

So equation y = mx + b becomes

[tex]y= \frac{8x}{9} + \frac{23}{9}[/tex]

Standard form is Ax + By = C

To get standard form , multiply the whole equation by 9

9y = 8x + 23

Subtract 8x on both sides

-8x + 9y = 23

Multiply the whole equation by -1

8x - 9y = -23

multiply. your answer is 11894.217.

this could be a cross multiply problem, so [tex]\frac{25.7}{x} =\frac{1}{462.81} =11894.217[/tex]

It starts off with 40 bacteria, which means no weeks have passed so far. That is why 40 pairs with 0 rather than 1.

Look at the picture.

Use the Pythagorean theorem to solve h:

[tex]h^2+5^2=7^2[/tex]

[tex]h^2+25=49[/tex]            subtract 25 from both sides

[tex]h^2=24\to h=\sqrt{24}[/tex]

ΔADC and ΔCDB are similar. Therefore the sides are in proportion:

[tex]\dfrac{h}{5}=\dfrac{x}{h}[/tex]       cross multiply

[tex]5x=h^2[/tex]      put the value of h

[tex]5x=(\sqrt{24})^2[/tex]

[tex]5x=24[/tex]       divide both sides by 5

[tex]x=4.8[/tex]

y = 5 + x → y = 5 + 4.8 = 9.8

Or other method. ΔADC and ΔACB are similar. Therefore the sides are in proportion:

[tex]\dfrac{y}{7}=\dfrac{7}{5}[/tex]        multiply both sides by 7

[tex]y=\dfrac{49}{5}\\\\\boxed{y=9.8}[/tex]

The vertex of the parabola y = (x – 5)² + 8 with a vertical axis of symmetry is the point (5, 8).

The question is asking for the vertex of the parabola y = (x − 5)² + 8 which has a vertical axis of symmetry. In the general equation for a parabola, y - k = a(x - h)², the vertex is denoted by the (h, k). So, comparing this with the given parabola equation, we can determine that the h value corresponds to the value inside the brackets in the (x – h)² part of the equation, and the k value corresponds to the term added or subtracted outside the squared term.

For the given equation, y = (x – 5)² + 8, we can see that h = 5 and k = 8. Therefore, the vertex of the parabola is at the point (5, 8).

The pair of points on the inverse function g, given that (-3,4) and (5,-2) are on function f, are (4,-3) and (-2,5), obtained by swapping the x and y coordinates of the original points.

To determine which pair of points are on function g, which is the inverse of function f, we swap the x and y coordinates of the given points on function f. The points (-3,4) and (5,-2) are on function f, so the corresponding points on the inverse function g would be (4,-3) and (-2,5), respectively. In the context of functions and their inverses, the dependence of y on x in one function becomes the dependence of x on y in the inverse function. This flipping of coordinates is an essential property of inverse functions and can be visualized by reflecting across the line y = x on a graph.

Answer:

y = 4.5 x

Step-by-step explanation:

If this is a proportional relationship, we can find the slope

m = (y2-y1)/(x2-x1)

m = (27-0)/(6-0)

m = 27/6

m=9/2

The slope is 9/2

The y intercept, where it crosses the y axis is 0

Using the slope intercept form of the equation y=mx+b

y = 9/2 x+0

y =9/2x

It wants the decimal form

y = 4.5 x

Answer:

31 and 28

Step-by-step explanation:

Let x represent the first number.

Let y represent the second number.

x + y = 59

x - y = 3

Use substitution method to solve.

x = y + 3

y + 3 + y = 59

2y + 3 = 59

Subtract both sides by 3.

2y = 56

Divide both sides by 2.

y = 28

Let's find the second number.

59 - 28 = 31

Check

31 -28 = 3

Answer The two numbers are 28 and 31.

The numbers are 31 and 28.

To find the two numbers where the sum is 59 and the difference is 3, we can set up two equations based on the information given.

Let the two numbers be x and y, where x > y. The equations would be:

Adding these two equations eliminates y, giving us:

2x = 62

Divide both sides by 2 to find x:

x = 31

Now substitute x back into one of the original equations to find y:

31 + y = 59

Subtract 31 from both sides:

y = 59 - 31

y = 28

Therefore, the two numbers are 31 and 28.

Answer:

x^3 +2x^2 -4x -8

Step-by-step explanation:

The factors of x^2 +4x +4 are (x +2)^2.

The factors of 4 -x^2 are -1(x -2)(x +2).

The least common denominator is the least common multiple of these, excluding the -1 multiplier. That multiple is ...

... (x +2)^2 × (x -2) = x^3 +2x^2 -4x -8

_____

Comment on the minus sign

When the given fractions are expressed using the denominator above, the second one will need to have its numerator sign adjusted. The two fractions are ...

The LCD or Least Common Denominator for the fractions 7/(x^2 + 4x + 4) and 5/(4 - x^2) is the product of the distinct denominators after factoring, which is (x+2)^2(4 - x^2), given they have no common factors.

The acronym LCD refers to the Least Common Denominator, which in mathematics, is the least common multiple of the denominators of a set of fractions. It is used to find a common denominator so that the fractions can be combined or compared. For the fractions 7/x^2 + 4x + 4 and 5/4 - x^2, the LCD would be the product of the distinct denominators assuming they cannot be factored into common factors. In this case, assuming x^2 + 4x + 4 cannot be further factored (it is a perfect square: (x+2)^2), the denominators are x^2 + 4x + 4 and 4 - x^2 (since we consider x^2 to have a negative coefficient here). Consequently, if there are no common factors, the LCD is (x^2 + 4x + 4)(4 - x^2) or (x+2)^2(4 - x^2).

We have, m = -2. Hence, the equation is

y = -2x + b

Now, use the point (-2,2) to find b

2 = -2(-2) + b

2 = 4 +b

b = -2

Hence, the equation of the line is y = -2x-2

Answer:

value of QZ = 8 units and QM =  12 units.

Step-by-step explanation:

Given: In triangle PQR has medians QM and PN that intersect at Z.

If ZM = 4 units.

In the figure given below;  second median divided the two triangles formed by the first median in the ratio 2:1.

We have to find the value of QZ and QM;

QZ:ZM = 2: 1

⇒ [tex]\frac{QZ}{ZM} = \frac{2}{1}[/tex]

Substitute the value of ZM =4 units and solve for QZ;

[tex]\frac{QZ}{4} = \frac{2}{1}[/tex]

Multiply both sides by 4 we get;

[tex]QZ = 2 \times 4 = 8 units[/tex]

Now, calculate QM;

QM = QZ+ZM = 8 + 4 = 12 units.

Therefore, the value of QZ and QM are; 8 units and 12 units
