Answer
A scientist uses a submarine to study ocean life.
*She begins at sea level, which is an elevation of 0 feet.
*She descends for 91 seconds at a speed of 2.2 feet per second.
*She then ascends for 32 seconds at a speed of 0.7 feet per second.
At this point, what is her elevation, in feet?
if you anserw corectly ill give you crown and more points
Answer:
-177.8 feet below sea level.
Step-by-step explanation:
First, we know that decend means to lower. Anything lower than 0 has to be negative. It says that she decends for 91 seconds at a speed of 2.2 feet per second. So first to find out how many feet she descended in those 91 seconds, you need to multiply 91*-2.2= -200.2. Then, it says that she ascends for 32 seconds at the speed of 0.7 feet per second. It's the same thing, but ascend means to go up. So, we multiply 32*0.7=22.4. Now we add the two numbers together to get -177.8.
Hope this helps!
Find the y-component of this
vector:
12.0 m
73.3°
Remember, angles are measured from
the +X axis.
y-component (m)
Answer:
The y-component is 11.49 m.
Step-by-step explanation:
Given that,
Vector = 12 m
Angle, θ = 73.3°
We need to find the y-component of this vector.
It can be calculated as follows :
[tex]v_y=v\sin\theta\\\\v_y=12\times \sin(73.3)\\\\=11.49\ m[/tex]
So, the y-component is 11.49 m.

Kim buys a carpet for a room. The carpet measures 6 metres by 6 metres. Kim pays £390 for the carpet. The room measures 5 metres by 5 metres. Work out the cost of the carpet she does not use.
Area = Length x width
Area of carpet = 6 x 6 = 36 square meters
Cost of carpet per square meter = total cost / area
Cost per square meter: 390 / 36 = £10.83
Area of room = 5 x 5 = 25 square meters.
Area of rug not used = area of room subtracted from area of carpet:
36 - 25 = 11 square meters
Cost of the carpet not used = area of carpet not used x cost per square meter
11 x 10.83 = 119.13
ANSWER: £119.13
Answer:
Area = Length x width
Area of carpet = 6 x 6 = 36 square meters
Cost of carpet per square meter = total cost / area
Cost per square meter: 390 / 36 = £10.83
Area of room = 5 x 5 = 25 square meters.
Area of rug not used = area of room subtracted from area of carpet:
36 - 25 = 11 square meters
Cost of the carpet not used = area of carpet not used x cost per square meter
11 x 10.83 = 119.13
ANSWER: £119.13

The ice cream cone has a radius of 3 cm and a height of 10 cm. If the scoop of ice cream is a sphere with radius of 3.5 cm, will all of the ice cream fit inside the cone?
Answer:
No, ice cream cannot fits inside the cone.
Step-by-step explanation:
radius of cone, r = 3 cm
height of cone, h = 10 cm
radius of ice cream sphere, R = 33.5 cm
The volume of the cone is
[tex]V =\frac {1}{3}\times \pi\times r^{2}\times h\\\\V = \frac{1}{3}\times 3.14\times 3\times 3\times 10\\\\V =94.2cc[/tex]
Volume of ice cream
[tex]V' =\frac{4}{3}\pi\times r^{3}\\\\V'= \frac{4}{3}\times 3.14\times 3.5^{3}\\\\V' = 179.5cc[/tex]
As the volume of ice cream is more than the volume of cone, so it cannot fit into the cone.

need help with this Q&A 3
Answer:
the second option
yes, because they are similar triangles
Step-by-step explanation:
the scaling factor is 3
3×3 = 9
3×7 = 21
so, the ratios of the sides remain the same, and the 90 degree angle remains the same. therefore, just one triangle is larger than the other, but the relative attributes and even the orientation are the same, so yes, since we don't know the absolute coordinates of the corners, indeed, the Hypotenuse of both triangles could be on the same line.

9 What is the volume of the cone below? * 267.95 in3 33.49 in3 133.97 in3
Answer:
Volume of cone = 33.49 inch³
Step-by-step explanation:
Missing information;
Height of cone = 8 inch
Diameter of cone = 4 inch
Find:
Volume of cone
Computation:
Radius of cone = Diameter of cone / 2
Radius of cone = 4 / 2

La moda es el valor de la variable que mas se repite, es decir , el valor que tiene mayor frecuencia. Calcula la moda de las puntuaciones que obtuvo cada deportista.
Answer:
Moda de Pablo: 4
Moda de Claudio: No tiene.
Step-by-step explanation:
Después de una pequeña búsqueda online, encuentre las tablas para este problema, las cuales se pueden observar abajo.
La moda es el valor que más se repite, para el caso de Pablo, podemos ver que el valor 14 se repite dos veces (de hecho es el único que se repite). Entonces es el valor que más se repite. Entonces la moda de Pablo es 14.
Para el caso de Claudio podemos ver que ningún valor se repite, entonces los datos de Claudio no tienen una moda.

(-5. 2) and (-3, -2)
(3.-4) and (-2, 1)
(-1.-2) and (1-4)
(5.-2) and (-1, -1)
Answer:
Step-by-step explanation:
Use the formula of distance between two points (x₁, y₁) and (x₂, y₂),
Distance = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
1). Distance between (4, 1) and (2, 2) = [tex]\sqrt{(4-2)^2+(1-2)^2}[/tex]
= [tex]\sqrt{5}[/tex]
= 2.24
2). Distance between (-5, 2) and (-3, -2) = [tex]\sqrt{(-5+3)^2+(2+2)^2}[/tex]
= [tex]\sqrt{20}[/tex]
= 4.47
3). Distance between (3, -4) and (-2, 1) = [tex]\sqrt{(3+2)^2+(-4-1)^2}[/tex]
= [tex]\sqrt{50}[/tex]
= 7.07
4). Distance between (-1, -2) and (1, -4) = [tex]\sqrt{(1+1)^2+(-4+2)^2}[/tex]
= [tex]\sqrt{8}[/tex]
= 2.83
5). Distance between (5, -2) and (-1, -1) = [tex]\sqrt{(5+1)^2+(-2+1)^2}[/tex]
= [tex]\sqrt{37}[/tex]
= 6.08
Therefore, increasing order of the distance will be 2.24 > 2.83 > 4.47 > 6.08 > 7.07
Answer:
Use the formula of distance between two points (x₁, y₁) and (x₂, y₂),
Distance =
1). Distance between (4, 1) and (2, 2) =

= 7.07
4). Distance between (-1, -2) and (1, -4) =
=
= 2.83
5). Distance between (5, -2) and (-1, -1) =

For a function g(x), the difference quotient is StartFraction 6 Superscript x + h minus 3 Baseline minus 6 Superscript x + 3 Baseline Over h EndFraction. What is the average rate of change of g(x) on the interval from x = –2 to x = 1?
Answer:
The average rate of change in that interval is 1.99
Step-by-step explanation:
Here we have that the difference quotient for g(x) is:
[tex]\frac{6^{x + h} - 3 - 6^x + 3}{h}[/tex]
Remember that for a general function f(x), the difference quotient is:
[tex]\frac{f(x + h) - f(x)}{h}[/tex]
So if we look at the difference quotient for g(x), we can conclude that:
[tex]g(x) = 6^x - 3[/tex]
Also remember that the average rate of change in an interval (a, b) is just:
[tex]\frac{g(b) - g(a)}{b - a}[/tex]
So here we want the average rate of change of g(x) in the interval from x = -2 to x = 1, this is:
[tex]R = \frac{(6^1 - 3) - (6^{-2} - 3)}{1 - (-2)} = \frac{6 - 6^{-2}}{3} = 1.99[/tex]
The average rate of change in that interval is 1.99
