What is the value of the rewritten expression when a = -5?
Answers
Answer:
-500
Step-by-step explanation:
(2a^4)^2
-----------------
a^0 a^5
We know ( xy) ^z = x^z y^z
so
(2a^4)^2 = 2^2 a^4^2
and x^y^z =x^(y*z) so a^4^2 = a^(4*2) = a^8
(2a^4)^2 = 4 a^8
We know that a^0 = 1
4 a^8
-----------------
1 a^5
We know x^y / x^z = x^ ( y-z)
4 a^( 8-5)
4 a^3
Let a = -5
4 ( -5) ^3
4 ( -125)
-500

Answers
Answer:
6Step-by-step explanation:
Given the expression g(c) = 6c/2, we are to find the value when c = 2
Substitute c = 2 into the expression
g(2) = 6(2)/2
g(2) = 12/2
g(2) = 6
Hence the result when c = 2 is 6

A tornado drops a piece of wood from a
height of 4,624 ft. If the equation for
height as a function of time is
h(t) = -16t2 + initial height where t is time
in seconds and h(t) is height in feet, how
many seconds will it take for the piece of
wood to hit the ground?
Answers
Answer:
Step-by-step explanation:
H(t) = -16[tex]t^{2}[/tex]+4.624 ( in feet)
0 = -16[tex]t^{2}[/tex] + 4,624
-4,624 = -16[tex]t^{2}[/tex]
-4,624 / -16 = [tex]t^{2}[/tex]
289 = [tex]t^{2}[/tex]
17 = t
so.. 17 seconds to hit the ground.. :)
The piece of wood 17 seconds takes to hit the ground.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
A tornado drops a piece of wood from a height of 4,624 ft.
Given that the equation for the height as a function of time is
h(t) = -16t² + initial height
Substitute height = 4,624 ft. in the equation,
h(t) = -16t² +4.624
At ground level, the value of h(t) is zero,
0 = -16t² + 4,624
16t² = 4,624
t² = 4,624/16
t² =289
t = 17
So, 17 seconds to hit the ground
Hence, the piece of wood 17 seconds takes to hit the ground.

in April
Answers
Answer: 3 3/4 inches
Step-by-step explanation:
From the question, we are informed that In April, it rained 1/4 of an inch on 15 different days.
The number of inches of rain that fell in April would be the multiplication of 1/4 by the total number of days. This would be:
= 1/4 × 15
= 15/4
= 3 3/4 inches

a video game store allows customers to rent games for 4.75 each. Customers can also buy a membership for $54 annually, and video games would only cost $2.50 each. Write and solve an equation to find the number of video games a customer would have to rent in a year in order for the two options to be equal...
equation:
solutionx(games):
Answers
24 video games
Step-by-step explanation:
Let x represent number of video games.
We have been given that a video game store allows customers to rent games for $4.75 each. So the cost of renting x video games would be 4.75x.
We are also told that customers can also buys a membership for $54 annually, and video games would only cost $2.50 each. The cost of renting x video games after membership would be 2.50x + 54
To find the number of video-games that will cost same for both options, we will equate both expressions as:
4.75x = 2.50x + 54
4.75x - 2.50x = 2.50x - 2.50x + 54
Therefore, a customer would have rent 24 video games in a year in order for the two options to be equal.

Answer: k = 3
because p - 1 is a factor of the equation
=> at p = 1, p^4 + p² + p - k =0
with p =1, we have: 1 + 1 + 1 - k = 0
⇔ k = 3
Step-by-step explanation:
Answer:
Solution,
since the factor of f(p) = p-1
we know, f(p)= 0
p=1 (from remainder theorem)
now,
f(p) =p^4+p^2+p-k
0= 1^4+1^2+1-k
0= 1+1+1-k
0= 3-k
k=3

The sum of deviation of a certain number of items measured from 2.5 is 50 and from 5.5 is - 250.Find the arthmetic mean
Answer = 3100
Answers
Answer:
3
Step-by-step explanation:
Given that :
A1 = 2.5 ; Σdx1 = 50
A2 = 5.5 ; Σdx2 = -250
Mean (m) = A + Σdx/N = 50
m = A + Σdx/N
m - A = Σdx/N
Nm - NA = Σdx
From the parameters given :
Nm - 2.5N = 50 - - - (1)
Nm - 5.5N = - 250 - - - (2)
Subtract (1) from (2)
3N = 300
N = 300/3
N = 100
Put N = 100 in either (1) or (2)
From (2):
100(m) - 5.5(100) = - 250
100m - 550 = - 250
100m = - 250 + 550
100m = 300
m = 300/100
m = 3
Hence, Arithmetic mean = 3
