Answer:
2. -1, -7, -19, -43, -91, -187,...
Step-by-step explanation:
[tex] \purple{ \bold{a_1 = - 1}}...(given) \\ a_n = 2a_{n - 1} - 5 \\ a_2 = 2a_{1} - 5 = 2( - 1) - 5 = - 2 - 5 = \\ \purple{ \bold{a_2 = - 7}} \\ \\ a_3 = 2a_{2} - 5 = 2( - 7) - 5 = - 14 - 5 \\ \purple{ \bold{a_3 = - 19}} \\ \\ a_4 = 2a_{3} - 5 = 2( - 19) - 5 = - 38 - 5 \\ \purple{ \bold{a_4 = - 43}}\\ \\ a_5 = 2a_{4} - 5 = 2( - 43) - 5 = - 86 - 5 \\ \purple{ \bold{ a_5 = - 91}}\\ \\ a_6 = 2a_{5} - 5 = 2( - 91) - 5 = - 182- 5 \\ \purple{ \bold{a_6 = - 187}}\\ [/tex]
Hence, first six terms of the given sequence are -1, -7, -19, -43, -91, -187,...

Which of the following describe the growth rate of the exponential function in the graph below?
Answer:
B)
Step-by-step explanation:
Let's check each answer:
A is incorrect. If that were the case, (0,1) to (1,3) would be (0,1) to (1,5) instead
B is correct. The y-coordinate gets multiplied by 3 each time (0,1)->(1,1*3)->(2,3*3)->(4,3*3*3)
C is incorrect. If that were the case, (1,3) to (2,9) would be (1,3) to (2,7) instead.
D is incorrect. If that were the case, (0,1) to (1,3) would be (0,1) to (1,4) instead.
Therefore, the correct answer is B.

Rhonda used unit cubes to make a rectangular prism. What is the volume of the prism? Prism with length as 7 unit cubes, height as 3 unit cubes and width as 2 unit cubes. A. 14 cubic units B. 21 cubic units C. 42 cubic units D. 63 cubic units
Answer:
42 cubic units
Step-by-step explanation:
A rectangle prism formula is V = l x h x w.
The length is 7
The height is 3
The width is 2
Then multiply 7, 3, and 2 together (7 x 3 x 2) = 42
The volume of the Rhonda rectangular prism will be 42 cubic units thus option (C) is correct.
What is volume?Volume is the scalar quantity of any object that specified occupied space in 3D.
For example, the space in our room is referred to as volume.
Volume has units of cube example meter³,cm³, etc.
The volume of the rectangular prism is given as,
V = length × height × width
Put length as 7 unit cubes, height as 3 unit cubes, and width as 2 unit cubes.
V = 7 x 3 x 2 = 42 units³.
Hence "The Rhonda rectangular prism will have a volume of 42 cubic units".

Answer:
The area of the shaded region is equal to difference of the sector contains that shaded region and the triangle.
The area of sector:
A_S = pi x radius^2 x 123/360
= pi x 18.6^2 x 123/360
= 371.346 (m2)
The area of triangle:
A_T = base x height x (1/2)
= (18.6 x sin(123/2) x 2) x (18.6 x cos(123/2)) x (1/2)
= 145.073 (m2)
=> Area of shaded region:
A = 371.346 - 145.073 = 226.273 = ~226.3 (m2)

Step-by-step explanation:
A rectangular playground is 10m longer than it is wide.The area of the playground is 1400m² Calculate the width and length of the playground. solve using quadratic formula please?
Answer:
[tex] 1400 = x(x+10)= x^2 +10x[/tex]
We can rewrite this expression like this:
[tex] x^2 +10 x -1400 =0[/tex]
And we can use the quadratic formula given by:
[tex] x = \frac{-b \pm \sqrt{b^2 -4ac}}{2a}[/tex]
Where [tex] a =1 , b=10 , c= -1400[/tex]
And replacing we got:
[tex] x = \frac{-10 \pm \sqrt{10^2 -4(10)(-1400)}}{2*1}[/tex]
And solving we got:
[tex] x_1 =32.75 , x_2 = -42.75[/tex]
And since the value can't be negative the answer would be x = 32.75 and the value of y = 32.75+10 =42.75
Step-by-step explanation:
For this case we know that we have a rectangular playground and the area can be founded with this formula:
[tex] A = xy[/tex]
Where x represent the width and y the length. From the problem we know that A =1400 m^2 and the heigth is 10m longer than the wide so we can write this condition as:
[tex] y = 10 +x [/tex]
And replacing this formula into the area we got:
[tex] 1400 = x(x+10)= x^2 +10x[/tex]
We can rewrite this expression like this:
[tex] x^2 +10 x -1400 =0[/tex]
And we can use the quadratic formula given by:
[tex] x = \frac{-b \pm \sqrt{b^2 -4ac}}{2a}[/tex]
Where [tex] a =1 , b=10 , c= -1400[/tex]
And replacing we got:
[tex] x = \frac{-10 \pm \sqrt{10^2 -4(10)(-1400)}}{2*1}[/tex]
And solving we got:
[tex] x_1 =32.75 , x_2 = -42.75[/tex]
And since the value can't be negative the answer would be x = 32.75 and the value of y = 32.75+10 =42.75
Answer:
Step-by-step explanation:
Given Data:
Area = 1400m²
L = 4+w
W= w
Area = L * W
1400 = ( 4+W) W ²
1400 = 4w + w ²
w ² + 4w - 1400 = 0
- b ± √ b ² - 4ac / 2a
Where;
a = 1
b = 4
c = -1400
- 4 ± √4² - 4(1)(-1400) / 2(1)
= - 4 ± 74.94 /2
= - 4 + 74.94 / 2 or - 4 - 74.94 / 2
= 35.47 or - 39.47
Would a piece of wood with a mass of 48 grams and a volume of 47.4 cm^3 float in water?
The piece of wood would sink if a piece of wood with a mass of 48 grams and a volume of 47.4 cubic cm, and a density is 1 g/cm³.
What is density?It is defined as the mass-to-volume ratio. The density indicates the object's density and is represented by the symbol. The density is measured in kilograms per cubic meter.
We have:
Mass of the piece of wood = 48 grams
The volume of the piece of wood = 47.4 cubic cm
As we know, from the definition of density, density is the mass-to-volume ratio.
d = mass/volume
d = 48/47.4
d = 1.01 g/cm³ ≈ 1 g/cm³
As we know,
It will float if the volume is larger than the mass and sink if the reverse is true.
Thus, the piece of wood would sink if a piece of wood with a mass of 48 grams and a volume of 47.4 cubic cm, and a density is 1 g/cm³.

Zugo delivers muffins for the Pastry-and-Muffin company. Each muffin is packed in its own
little box. An individual muffin box has the shape of a cube, measuring three inches on
each side. Zugo packs the individual muffin boxes into a larger box. The larger box is also
in the shape of a cube, measuring two feet on each side. How many of the individual
muffin boxes can fit into the larger box?
Answer:
512
Step-by-step explanation:
You can figure this a couple of ways.
1) Figure the number of muffin boxes that goes into each dimension of the larger box:
(2 ft)/(3 in) = (24 in)/(3 in) = 8 . . . . muffin boxes in each direction.
Then the total number of muffin boxes that will fit in a larger box is ...
8×8×8 = 512
512 muffin boxes can fit into the larger box.
__
2) The volume of a muffin box in cubic feet is ...
((3 in)/(12 in/ft))^3 = (1/4 ft)^3 = 1/64 ft^3
The volume of a larger box in cubic feet is ...
(2 ft)^3 = 8 ft^3
Then the number of smaller boxes that will fit in the larger box is ...
(8 ft^3)/(1/64 ft^3) = 8×64 = 512
512 muffin boxes can fit into the larger box.
