Answer:
x = -30
Step-by-step explanation:
-24 = 6 + x
we'll subtract 6 to get x alone:
-24 - 6 = x
-30 = x
____________
then to check, we plug it back in
-24 = 6 + (-30)
-24 = -24 true! so -30 is right :)
Answer:
-30
Step-by-step explanation:
You can backtrack to find x:
-24-6=-36
-30+6=-24

Am I starting this off right? What does it mean to find instantaneous velocity?
Answer:
yesv(t) gives the instantaneous velocity at time t(a) correct
(b) -48 ft/s
(c) -32 ft/s; -64 ft/s
(d) 9.257 s
(e) -296.216 ft/s
Step-by-step explanation:
You are given an equation of motion and asked to find velocity and time at different points in the motion. This requires you differentiate the position function to find velocity, and that you solve the position function to find the time at a particular position.
__
(a)The coin is "dropped", so is presumed to have no initial velocity. The initial height is given as 1371 feet. Putting these values into the given equation, you have ...
s(t) = -16t² +1371
The velocity is the derivative of this function:
v(t) = -32t
__
(b)The average velocity on an interval is the change in position divided by the change in time:
(s(2) -s(1))/(2 -1) = ((-16·2² +1371) -(-16·1² +1371))/1 = -16(4 -1) = -48 . . . ft/s
(Note: the average velocity for a quadratic position function is the velocity at the midpoint of the interval: v(1.5) = -32(1.5) = -48 . . . ft/s.)
__
(c)Use the velocity function you found in part (a) to determine the instantaneous velocity at the given times:
v(1) = -32(1) = -32 . . . ft/s
v(2) = -32(2) = -64 . . . ft/s
__
(d)The coin will reach the ground when s(t) = 0. Solving for t, we find ...
s(t) = 0
-16t² +1371 = 0
1371 = 16t²
t = √(1371/16) = (√1371)/4 ≈ 9.257 . . . . seconds
__
(e)The velocity at impact will be ...
v(√1371/4) = -32(√1371/4) = -8√1371 ≈ -296.216 . . . ft/s
1. determine if the functions are inverse functions
f(x) = x+6
g(x) = x-6
2. determine if the functions are inverse functions
f(x) = -3x-9
g(x) = -1/3x-3
Answer:
Question 1
The function [tex]f(x) = x + 6[/tex] is one-to-one, so it does have an inverse.
The inverse of +6 is -6, so [tex]f^{-1}(x)=x-6[/tex]
Therefore, g(x) is the inverse of f(x).
Question 2
The function [tex]f(x) = -3x -9[/tex] is one-to-one, so it does have an inverse.
To find the inverse, replace f(x) with y:
[tex]\implies y = -3x -9[/tex]
Rearrange the equation to make x the subject:
[tex]\implies y+9= -3x[/tex]
[tex]\implies x=-\dfrac13(y+9)[/tex]
[tex]\implies x=-\dfrac13y-3[/tex]
Replace x with [tex]f^{-1}(x)[/tex] and y with x:
[tex]\implies f^{-1}(x)=-\dfrac13x-3[/tex]
Therefore, g(x) is the inverse of f(x).
5. Kiran is solving the equation Vx+ 2 – 5 = 11 and decides to start by squaring both sides. Which equation results if Kiran squares both sides as his first step? A. x + 2 – 25 = 121 B. x + 2 + 25 = 121 х C. x + 2 – 107x + 2 + 25 = 121 = х = D. x + 2 + 107x + 2 + 25 = 121 (From Unit 3, 9.)
The equation that results if Kiran squares both sides as his first step is gotten as; x + 2 - 10√(x + 2) + 25 = 121
How to simplify algebra?We want to simplify the expression;
[√(x + 2)] - 5 = 11
Squaring both sides is;
([√(x + 2)] - 5) * ([√(x + 2)] - 5) = 11 * 11
⇒ x + 2 - 10√(x + 2) + 25 = 121
Thus, the correct answer is;
x + 2 - 10√(x + 2) + 25 = 121

4) Cody invests $2,733 in a retirement
account with a fixed annual interest rate of
9% compounded 12 times per year.
How
long will it take for the account balance to
reach $9,589.78?
Answer:
t = 14 years
Step-by-step explanation:
r = R/100
r = 9/100
r = 0.09 per year,
Then, solve the equation for t
t = ln(A/P) / n[ln(1 + r/n)]
t = ln(9,589.78/2,733.00) / ( 12 × [ln(1 + 0.09/12)] )
t = ln(9,589.78/2,733.00) / ( 12 × [ln(1 + 0.0075)] )
t = 14 years
Summary:
The time required to get a total amount of $9,589.78 with compoundeded interest on a principal of $2,733.00 at an interest rate of 9% per year and compounded 12 times per year is 14 years.

Answer:
D
Step-by-step explanation:
You can combine like terms meaning (8x+14)+ (9x-5) is 17x+9
Hi!
Given:
[tex](8x+14) + (9x-5)[/tex]
As we are adding the two groups, we can safely take them out of parentheses, as none of the signs will change:
[tex]8x+14+9x-5[/tex]
Now, we can rearrange them to make it easier, placing like terms next to each other:
[tex]8x+9x+14-5[/tex]
Now, add like terms:
[tex]17x+9[/tex]
Therefore, your answer is D.

Answer:
A) R24.10
B) R25.90
((ASSUMING THERES NO TAXES WITH THE PAYMENT))
Step-by-step explanation:
A)
first add up the costs of each item to get the ttal cost with addition as follows...
9.50 + 0.50 + 2.75 + 11.35 ((Adding like terms by adding 0.50 to 9.50 equaling 10.00))
10.00 + 2.75 + 11.35 ((adding the more simple options togeter since .75 is a more common fraction at 3/4))
12.75 + 11.35 ((finnishing off the system by adding the last two numbers together equaling to 24.10))
therefore Thabo spent a total of 24.10
B)
to find out the change, all we need to do is subtract the total cost from the total amount Thabo used to pay as shown below
50.00 - 24.10
in conclusion, Thabo would have R25.90 in change from the transaction ((assuming theres no tax))

7. Saturday night, Larry is attending the concert of his favorite rock band. Tickets were $250 plus 6% tax. Parking is $20 for the evening. While there, Larry purchases a T-shirt for $35 plus 7% tax and a meal with a beverage for $25. How much did he spend altogether to attend the concert?
Answer:
$347.45
Step-by-step explanation:
total = tickets + parking + t shirt + meal
tickets = 250 + 6% tax
6% tax is of 250, so this is equal to
250 + 6% of 250
6% = 0.06 because we divide by 100 to convert to a decimal from a percentage
thus, tickets = 250 + 0.06 of 250 = 250 * 1 + 0.06 * 250 + 1.06 * 250 = 265
parking = 20
use a similar strategy from the tickets and apply that to the t shirt
t shirt = 35 + 7 % tax = 35 + 0.07 * 35 = 1.07 * 35 = 37.45
meal = 25
total = 265 + 20 + 37.45 + 25 = $347.45

102 mm --> 125 mm --> 10.4 cm --> 0.12 m.
Explanation:
Millimeters (mm) is smaller than centimeters (cm). Centimeters are smaller than meters (m).
And, since both 125 mm and 102 mm has the same units of measurement, 125>102.
So, 102 goes in front of 125.
And then the rest of the order is completed by comparing the units of measurement.

A school playground is in the shape of a parallelogram. The base of the parallelogram is six times as long as the height. The area of the playground is 5040 square feet. What is the length of the longer side of the playground? Round to the nearest foot.
Hint : Use A = bh.
180 ft
30 ft
840 ft
174 ft
Answer:
Option D, 174 ft
Step-by-step explanation:
Step 1: Create an equation
[tex]B = 6H[/tex]
[tex]Area = (6H) * H[/tex]
Step 2: Divide both sides by 6
[tex]5040\ ft^2 = 6H^2[/tex]
[tex]\frac{5040\ ft^2}{6} = \frac{6H^2}{6}[/tex]
[tex]840\ ft^2 = H^2[/tex]
Step 3: Square root both sides
[tex]\sqrt{840\ ft^2} = \sqrt{H^2}[/tex]
[tex]29\ ft = H[/tex]
Step 4: Find the base
[tex]A = B * H[/tex]
[tex]5040\ ft^2 = B * 29\ ft[/tex]
[tex]\frac{5040\ ft^2}{29\ ft} = \frac{B*29\ ft}{29\ ft}[/tex]
[tex]174\ ft = B[/tex]
Answer: Option D, 174 ft

A. 243 Ft.
B. 61 FT.
C. 370 FT.
D.121 FT.
Answer:
Option A, [tex]L = 243\ ft[/tex]
Step-by-step explanation:
Step 1: Create an equation
[tex]Length = 4 * Width[/tex]
[tex]Area = (4 * W) * W[/tex]
[tex]Area = 4 W^2[/tex]
Step 2: Solve for W
[tex]14800\ ft^2 = 4 W^2[/tex]
[tex]\frac{14800\ ft^2}{4} = W^2[/tex]
[tex]3700\ ft^2 = W^2[/tex]
[tex]\sqrt{3700\ ft^2} = \sqrt{W^2}[/tex]
[tex]61\ ft = W[/tex]
Step 3: Solve for L
[tex]Length = 4 * Width[/tex]
[tex]L = 4 * 61\ ft[/tex]
[tex]L = 243\ ft[/tex]
Answer: Option A, [tex]L = 243\ ft[/tex]
Factor the polynomial and use the zeros to identify its graph. x4 − 5x3 − 20x2 + 60x + 144
The zeros of the polynomial are -3, -2, 4 and 6 and the graph of the polynomial is graph (a)
How to factor the polynomial?The polynomial is given as:
P(x) = x^4 - 5x^3 - 20x^2 + 60x + 144
Expand the polynomial function
P(x) = x^4 - 10x^3 + 5x^3 + 24x^2 - 50x^2 + 6x^2 + 120x - 60x + 144
Rewrite the function as:
P(x) = x^4 - 10x^3 + 24x^2 + 5x^3 - 50x^2 + 120x + 6x^2 - 60x + 144
Factorize the function
P(x) = x^2(x^2 - 10x + 24) + 5x(x^2 - 10x + 24) + 6(x^2 - 10x + 24)
Factor out x^2 - 10x + 24
P(x) = (x^2 + 5x + 6)(x^2 - 10x + 24)
Expand each bracket
P(x) = (x^2 + 3x + 2x + 6)(x^2 - 4x - 6x + 24)
Factorize each bracket
P(x) = [x(x + 3) + 2(x + 3)][x(x - 6) - 4(x - 6)]
Factor out x + 3 and x - 6
P(x) = (x + 3)(x + 2)(x - 4)(x - 6)
Set to 0
(x + 3)(x + 2)(x - 4)(x - 6) = 0
Solve for x
x =-3, -2, 4 and 6
Hence, the zeros of the polynomial are -3, -2, 4 and 6 and the graph of the polynomial is graph (a)
