The answer is C because I dont know
An object moves such that acceleration a(t)=2(1-3t). Given v(0)=-5 and x(0)=4, find x(1).
I know the answer is -1, just not too sure on how to get the work, thanks!
Answer:
x(1) = -1
Step-by-step explanation:
Given the equation for acceleration of the object as;
a(t)=2(1-3t)
a(t) = 2-6t
Integrate to get the velocity
v(t) = 2t-6t²/2 + C
v(t) = 2t-3t²+C
If v(0) = -5
when t = 0 v = -5
-5 = 2(0)-3(0)²+C
-5 = C
C = -5
v(t) = 2t-3t²-5
To get the displacement x(t), we will integrate the velocity function
x(t) = 2t²/2-3t³/3-5t+C
x(t) = t²-t³-5t+C
If x(0) = 4
At t = 0, x(t) = 4
4 = 0²-0³-5(0)+C
4 = C
C = 4
x(t) = t²-t³-5t+4
Get x(1)
x(1) = 1²-1³-5(1)+4
x(1) = 1-1-5+4
x(1) = -5+4
x(1) = -1
Hence x(1) = -1

Expand the following exercise
Answer:
Step-by-step explanation:
Use FOIL method
(2 - 7x)(-x + 2) = 2*(-x) + 2*2 + (-7x)*(-x) + (-7x)*2
= -2x + 4 + 7x² - 14x {Combine like terms}
= 7x² - 14x - 2x + 4
= 7x² - 16x + 4
x²(2-7x)(-x + 2)= x² (7x² - 16x + 4)
= x²*7x² - 16x * x² + 4x²
[tex]7x^{2+2} -16x^{1+2} + 4x^{2}\\\\= 7x^{4} - 16x^{3} + 4x^{2}[/tex]

What are the steps to solve 5x+7+3x-4=?
Answer:
x= -3 / 8
Step-by-step explanation:
5x+7+3x-4=0
Sum 5x and 3x
8x+7-4=0
Subtract 7-4
8x+3=0
Move the constant to the other side and change his symbol with his opposite
8x=-3
8 is multiplying x, the opposite of multiplying is dividing, so it divide the -3 (under it)
x= -3 / 8

Over 20 years, the population of a town
decreased by 275 people to a population of
850. Write and solve an equation to find the
original population.
Answer:
p= 1125
Step-by-step explanation:
p-275= 850
p- 275= 850
+ 275 +275
p= 1125
P= the original population minus D= decrease in population is equal to C= the current population
p-d=c
Answer:
1125 people
Step-by-step explanation:
We don't know the exact quantity, but we know it has decreased by 275 and it's currently 850, so we will represent it like this:
x - 275 = 850
x = original amount of people
Now we just solve it like any equation
x = 850 + 275
x = 1125

What's ƒ(g(4)) if ƒ(x) = 3x2 – 3x + 6 and g(x) = 2x?
Answer:
Step-by-step explanation:
In order to do f(g(4)), we need to find what g(4) is in order to input it into the function f(x).
g(4) = 2(4) = 8
Now do f(8) because that's the value of g(4)
f(8) = 3(8^2) - 3(8) + 6 = 174

You simply 2/72 which is 12/2, then simplify /8 which is 2/2.
You combine 2/2 and /2 which is 3/2.
The equation should be 12/2 over 3/2 so you simplify it which will give you 4.
(By simplifying 12/2 over 3/2, you cross out /2 and convert 12 over 3 into a whole number)

The figure below shows a line graph and two shaded triangles that are similar:
A line is shown on a coordinate grid. The x-axis values are from negative 15 to positive 15 in increments of 3 for each grid line. The y-axis values are from negative 5 to positive 5 in increments of 1 for each grid line. The line passes through the ordered pairs negative 12, 4, and 0, 0, and 12, negative 4. A shaded right triangle is formed so that its hypotenuse is from ordered pair 0, 0 labeled as O to 6, negative 2 labeled as A, one leg is from 0, 0 to 0, negative 2, and the second leg is from 0, negative 2 to 6, negative 2. Another shaded right triangle is formed with the hypotenuse from 6, negative 2 to 9, negative 3 labeled as B, one leg is from 6, negative 2 to 6, negative 3, and the second leg is from 6, negative 3 to 9, negative 3.

Step-by-step explanation:
The 10th, 4th and 1st term of an A.P are three consecutive find the common ratio of the G.P and the sum of the 6th term, taking the 1st term to be 4
Answer:
S_6 = 252
Step-by-step explanation:
We are told that the 10th, 4th and 1st term of an A.P are three consecutive terms of a G.P.
Now,formula for nth term of an AP is;
a_n = a + (n - 1)d
Thus;
a_10 = a + (10 - 1)d
a_10 = a + 9d
Also;
a_4 = a + (4 - 1)d
a_4 = a + 3d
First term is a.
Thus, since they are consecutive terms of a G.P, it means that;
(a + 9d)/(a + 3d) = (a + 3d)/a
Cross multiply to get;
a(a + 9d) = (a + 3d)(a + 3d)
a² + 9ad = a² + 6ad + 9d²
a² will cancel out to give;
9ad - 6ad = 9d²
3ad = 9d²
Divide both sides by 3d to get;
a = 3d
We are told that the first term is 4.
Thus, 4 = 3d
d = 4/3
We saw earlier that ratio of the GP is (a + 3d)/a
Thus; r = (4 + 3(4/3))/4 = 8/4 = 2
Sum of n terms of a G.P is given by;
S_n = a(rⁿ - 1)/(r - 1)
S_6 = 4(2^(6) - 1)/(2 - 1)
S_6 = 252
