Answer:

  f(5) = 160

Step-by-step explanation:

The first several terms of the sequence are ...

  10, -20, 40, -80, 160, -320, 640, ...

Each term is -2 times the previous term.

  f(5) = 160

Answer:

none Geometric mean cannot be calculated for negative values

Step-by-step explanation:

Given equations;

y₁ = 3x - 8               -------------------(i)

y₂ = 0.5x + 7          --------------------(ii)

To fill the table, substitute the values of x into equations (i) and (ii)

=> At x = 0

y₁ = 3(0) - 8 = -8

y₂ = 0.5(0) + 7 = 7

=> At x = 1

y₁ = 3(1) - 8 = -5

y₂ = 0.5(1) + 7 = 7.5

=> At x = 2

y₁ = 3(2) - 8 = -2

y₂ = 0.5(2) + 7 = 8

=> At x = 3

y₁ = 3(3) - 8 = 1

y₂ = 0.5(3) + 7 = 8.5

=> At x = 4

y₁ = 3(4) - 8 = 4

y₂ = 0.5(4) + 7 = 9

=> At x = 5

y₁ = 3(5) - 8 = 7

y₂ = 0.5(5) + 7 = 9.5

=> At x = 6

y₁ = 3(6) - 8 = 10

y₂ = 0.5(6) + 7 = 10

=> At x = 7

y₁ = 3(7) - 8 = 13

y₂ = 0.5(7) + 7 = 10.5

=> At x = 8

y₁ = 3(8) - 8 = 16

y₂ = 0.5(8) + 7 = 11

=> At x = 9

y₁ = 3(9) - 8 = 19

y₂ = 0.5(9) + 7 = 11.5

=> At x = 10

y₁ = 3(10) - 8 = 22

y₂ = 0.5(10) + 7 = 12

The complete table is attached to this response.

(ii) To find the solution of the system of equations using the table, we find the value of x for which y₁ and y₂ are the same.

As shown in the table, that value of x = 6. At this value of x, the values of y₁ and y₂ are both 10.

Answer:

  43.1 in³

Step-by-step explanation:

The volume can be computed using the formula ...

  V = (π/4)d²h . . . . where d is the diameter and h is the height

For your dimensions, the volume is ...

  V = (π/4)(2.8 in)²(7 in) ≈ 43.103 in³

A full can contains a volume of about 43.1 cubic inches.

Answer:

7480 hours

Step-by-step explanation:

440 - 100 = 340

LCM of 440 and 340

440 = 2 × 2 × 2 × 5 × 11

340 = 2 × 2 × 5 × 17

LCM = 2 × 2 × 2 × 5 × 11 × 17

LCM = 7480

Step-by-step explanation:

Hey there!

The centre of a circle is (-1,-1) and radius is 1 unit.

From centre of a circle (h,k) and radius "r" , the equation is (x-h)²+(y-k)² = r²

Then;

(x+1)² + (y+1)² = 1²

Therefore, the equation of a circle is (X+1)² + (y+1)² = 1.

Answer:

length = 22

Width = 17

Step-by-step explanation:

78 = 2(w+5) + 2(w)

78 = 2w + 10 + 2w

78 = 4w + 10

68 = 4w

w = 17

l = 17 + 5 = 22

Answer:

Between 4 and 5

Step-by-step explanation:

Given

See attachment for graph

Required

Between which points is g(x) = 0

From the attachment, we can see that the graph crosses the x-axis at 4... and -1...

This means that

g(x) = 0 between 4 and 5

g(x) = 0 between -1 and -2

Going by the available options,

g(x) = 0 between 4 and 5

Answer:

Below

Step-by-step explanation:

To find the volume of a cone, you can use the equation V=π r^2 (h/3)

Because the diameter is 7, the radius is 3.5 inch ( r=1/2 d)

V = π (3.5^2)(37/3)

   = 474.64 in^3

I hope that is correct good luck!

Answer:

474.642

Step-by-step explanation:

To find out the volume of the cone is using V= 1/3 TTR^2 * H

We know TT is pie, pie is 3.19 and the radius of the cone is 3.5 inches because half of seven is 3.5.

V=1/3 3.14 * 3.5 * 3.5 * 37 = 474.642

Answer:

x = 48.

Step-by-step explanation:

If AE is 921, then EC is equivalent to that. First, you subtract 9 from 921, then divide by nineteen to get your answer: x = 48.

Answer: $108.60

Step-by-step explanation:

Initial cost: $95.50

Tip is an additional cost. They want to give a tip of 20%, so they will give additional 20% of the initial cost.

$90.50 + (90.50 * 0.2)

= $90.50 + $18.10

= $108.60

Answer:

3/4

Step-by-step explanation:

Exponents first  ( We know a^-b = 1/ a^b)

f(-2)=3• 1/2^2

     =3 * 1/4

Answer:

6 1/6

Step-by-step explanation:

Divide the numerator (19) by the denominator (6)

Write down the whole number result which in this case would be 3

Use the remainder as the new numerator over the denominator. This is the fraction part of the mixed number. which in this case is 1/6

therefore the answer is 6 1/6

Answer:

1. True, because when performing the calculations in both sides of the equation, we find that the left value is indeed the same as the right value

4-3+5 = 1+5 = 6

-6+8+4 = 2+4 = 6

6=6, so the sentence is correct

2+5 = 19-12 => 7=7, true

5-4-3-2-1 = 30-34-1 => -5=-5, true

2(x+5)-4x = 3(x-2)-5x+16

=> 2x+10-4x = 3x-6-5x+16

=> -2x+10 = -2x+10, true

Step-by-step explanation:

the other two sentences lead to false

4/5 + 1/5 = 2 - 1 - 1, => 5/5 = 1 = 0, false

2(x+8) = 2x-8, => 2x+16 = 2x-8 => 16=-8, false

Answer:

No

Step-by-step explanation:

The coefficents of x³ and x² are 1 and -6 respectively

neither has a factor of 4

because the multiplication Slope of 2 perpendicular is -1

Answer:

Step-by-step explanation:

y = 3x³ -4

the inverse is found by changing x with y and y with x than solve for y

x = 3y³ -4

x+4 = 3y³-4+4; add 4 to both sides

x+4 = 3y³

(x+4)/3 =y³ ;divide both sides by 3

∛((x+4)/3) = y ;cube root both sides

the inverse function of f(x) =3x³-4 is

[tex]f(x)^{-1} =\sqrt[3]{\frac{x+4}{3} }[/tex]

Given:

M is the midpoint of AB.

M(2,0) and A(-3, 3).

To find:

The coordinates of point B.

Solution:

Midpoint formula:

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

Let the coordinates of point B are (a,b). Then, using the midpoint formula, we get

[tex](2,0)=\left(\dfrac{-3+a}{2},\dfrac{3+b}{2}\right)[/tex]

On comparing both sides, we get

[tex]\dfrac{-3+a}{2}=2[/tex]

[tex]-3+a=2\times 2[/tex]

[tex]a=4+3[/tex]

[tex]a=7[/tex]

And,

[tex]\dfrac{3+b}{2}=0[/tex]

[tex]3+b=0[/tex]

[tex]3+b-3=0-3[/tex]

[tex]b=-3[/tex]

Therefore, the coordinates of point B are (7,-3).
