Step-by-step explanation:
There are a few ways of visualizing the expression, but Ill try to show it to easiest way possible.
[tex]x^\frac{3}{2} =(x^3)^\frac{1}{2}[/tex]
Notice nothing was changed because of the property of exponents. An exponent to a power means to multiply them. A thing you should remember for all future cases is that the one-half power means square root. It is the exact same thing. Therefore the new expression I created is the square root of 'x' cubed.
A:) This would be equivalent to x^2/3
B:) This is equivalent to x^3/2 because the square root is the 1/2 power to the power of 3.
C:) This would be equivalent to x^2/3
D:) This is equivalent to x^3/2 because the square root is the 1/2 power, but multiplied by the power under the radical.
E:) If this answer is to the third power, then it is equivalent. I cannot tell from this picture.

Answer:
103 ft^2
Step-by-step explanation:
Long sides: 2(8*4) = 64 ft^2
Under side: 3*8 = 24 ft^2
Triangles: (2(3*5))/2 = 15 ft^2
64+24+15 = 103
Answer:
103
Step-by-step explanation:
the base = 3x8 = 24
the sides are= 4 x 8 = 32
two sides = 64
triangle = 5x 3 x1/2 = 7.5
7.5 x 2 = 15

A snail travels at a rate of 2.37 feet per minute.
a. Write a rule to describe the function.
b. How far will the snail travel in 6 minutes
A. d(t) = t/2.37; 2.53ft
B. d(t) = t + 2.37; 8.37 ft
C. d(t) = 2.37t; 14.22 ft
D. d(t) = 6t; 14.22 ft
Answers
Answer:
C. d(t) = 2.37t; 14.22 ft
Step-by-step explanation:
2.37 per minute is multiplication so A and B are definitely wrong
Another way to check is 2.37*6=14.22 so the answer is C
Answer:
D. d(t) = 6t; 14.22 ft
Step-by-step explanation:
d(t)= 2.37t; 14.22 ft
d(t)= 2.37t; 14.22 ft
Answer:
a. f(t)=2.37t
b. 14.22 feet
Step-by-step explanation:
We are given that:
A snail travels at a rate of 2.37 feet per minute.
a. write a rule to describe a function.
Let t describe the time and f(t) be a function how far snail travels
then, f(t)=2.37×t
where the unit of t is in minutes and that of f(t) is feet
b. how far will the snail travel in 6 minutes
we have to find f(t) at t=6
f(6)= 2.37×6
= 14.22 feet
Hence, snail traveled 14.22 feet in 6 minutes
2.37/minute
14.22 feet in six minutes
Answer:
Rule for Distance is f(t) = 2.37t and distance covered in 6 minutes is 14.22 feet.
Step-by-step explanation:
Speed of Snail = 2.37 feet per minute
To write the rule we use relation of Speed, Distance and time
Distance = Speed × Time
So, Distance cover by snail in t minutes is given by f(t) = 2.37 × t
⇒ f(t) = 2.37t
Distance traveled by Snail in 6 minutes , f(6) = 2.37 × 6 = 14.22 feet
Therefore, Rule for Distance is f(t) = 2.37t and distance covered in 6 minutes is 14.22 feet.

hello, could someone help me with this question, thank you.
Answers
It's C.
Basically, when youre dividing something, the bases would stay the same but the exponents would change. For division, you'd have to substract the exponent of the denominator from the denominator (of like bases, of course)
In this case, it's 10^8-(-3).
The only reason it's not 10⁵ is because of the negative 3. If it were a positive 3, it would become 10⁵.
What is the measure of all exterior angles of a pentagon
Answers
Answer:
72 degrees for each exterior angle and 360 degrees for all of them summed.
Step-by-step explanation:
An exterior angle of a polygon is the angle between the line extending one of its sides and the next side. As you go around a regular n sided polygon doing this, you will rotate through a complete circle of 360 degrees. All these angles are equal, so each one is 360/n.
For the pentagon, n=5, so the sum of all its exterior angles is 360 degrees and each exterior angle is 360/5=72 degrees.

if y varies directly as the square root of x and y=3, x=3. calculate y when x=64
Answers
Answer:
y = 64√3
Step-by-step explanation:
Step(i):-
Given that the 'y' varies directly as √x
⇒ y∝ √x
⇒ y = k√x
Put y=3 and x=3
3 = k ×√3
√3 k = √3×√3
After cancellation '√3' on both sides, we get
k = √3
Step(ii):-
Given that x=64 and k = √3
We have a function y = k√x ..(i)
substitute x =64 and k = √3 in equation (i)
y = √3 × 64
y = 64√3

Answers
Answer:
a) $654
b) 27 unidades cuadradas
c) 721
Step-by-step explanation:
a) ¿Cuál es el valor de un bolígrafo cuando la docena se compra por $ 7848?
Una docena = 12
Por eso:
12 bolígrafos = $ 7848
1 bolígrafo = $ x
Cruz multiplicar
12 bolígrafos × $ x = 1 bolígrafo × $ 7848
$ x = 1 bolígrafo × $ 7848/12
$ x = $654
b) Área de un triángulo ¿9 unidades de base y 6 unidades de altura?
Área de un triángulo =
= 1/2 × Base × Altura
1/2 × 9 × 6
= 27 unidades cuadradas
c) Cien veces la suma de 4.5 con 2.71
Esto se calcula como:
100 × (4,5 + 2,71)
= 100 × (7.21)
