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.
HELPP! ASAP PLS!! Find the surface area of the composite solid. Leave your answer in exact terms.
Answer:
Step-by-step explanation:
First find the surface area of the clyinder and find the area circles and subtract
Then find the surface area of a cone, remove the circle area and double it.
Clyinder surface area (without circle area) 2πrh+2πr2=2·π·4·6+2·π·42≈251.32741
251.32741 - 50.2 - 50.2
Cone area: A=πr(r+h2+r2)=π·4·(4+32+42)≈113.09734
113.09734 - 50.2 - 50.2
Total: 12.69734 + 150.92741 = 163.62475

Paul is decorating cupcakes. He can decorate 3/4 of a cupcake per minute. At this rate, how many cupcakes can he decorate in 12 minutes?
Answer:
3/4 x 12/1 because if you can decorate 3/4 a cupcake per minute, you multiply 3/4 by 12 to find the total amount of cupcakes he could decorate. 3/4 x 12/1 = 9 Paul can decorate 9 cupcakes in 12 minutes.
Step-by-step explanation:

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

A cafeteria is in the shape of a rectangle. The length of the rectangle is four times its width. The area of the cafeteria is 14,800 square feet. What is the length of the cafeteria? Round to the nearest foot.
Hint: Use A = LW.
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]
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
Prove or disprove that the point lies on the circle centered at the origin
Answer:
Step-by-step explanation:
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).

Answer: 190 m³
Step-by-step explanation:
We will calculate the volume of the prisms separately, and then add them together.
V = L * W * H
[1]
V = L * W * H
V = 9 * 2 * 5
V = 90 m³
[2]
V = L * W * H
V = 5 * 5 * 4
V = 100 m³
[Adding together]
100 + 90 = 190 m³
The volume is 190 m³

Nancy wants to buy a sweater that is priced at $75. If the store is running a 60% off sale, what will be the
amount of the discount and the sale price of the sweater?
Answer:
$30.00
Step-by-step explanation:
The original price of the sweater is $75.00. The new sale price is the original price of 100% less 60% of the original price. That means the sales price is 40% of the original price.
You can do this 2 ways:
1. $75 x 60% or .60 = $45
$75-45 = $30
or
2. $75 x 40% or .40 = $30

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.
