Which function has a vertex at (2, -9)?
f(x) = -(x - 3)2
f(x) = (x + 8)
f(x) = (x - 5)(x + 1)
f(x) = -(x - 1)(x - 5)
Answer:
C
Step-by-step explanation:
The first two are not parabola at all and the last one when graphed gives you a vertex of (3,9). The correct answer that gives you the vertex if (2,-9).

What is the slope of the graph?
Answer:
1
Step-by-step explanation:
Slope is essentially just the change in y divided by the change in x. "Change in y" just means the difference in the y-coordinates, while "change in x" means the difference in the x-coordinates.
Let's choose any two points: (-1, 0) and (0, 1). The difference in the y-coordinates is: 1 - 0 = 1. The difference in the x-coordinates is: 0 - (-1) = 1. Divide these:
1 ÷ 1 = 1
Thus, the slope is 1.
We can use the points (-1, 0) and (0, 1) to solve.
Slope formula: y2-y1/x2-x1
= 1-0/0-(-1)
= 1/1
= 1

Which is true about the volume or surface area of these prisms?
The surface area of A is greater than the surface area of B.
The surface area of B is greater than the surface area of A.
The volume of A is greater than the volume of B.
The volume of B is greater than the volume of A.
Answer:
the surface area of A is greater than the surface area of B
Step-by-step explanation:
A surface area: 112
B surface area: 104
A area: 60
B area: 60
Answer:
The surface area of A is greater than the surface area of B
Step-by-step explanation:
Volume = L x W x H
A= 3 x 2 x 10
= 60m^3
B = 2 x 6 x 5
= 60m^3
Surface Area = 2(l x w) + 2(l x h) + 2(w x h)
A = 2(3 x 2) + 2(3 x 10) + 2(2 x 10)
= 2x6 + 2x30 + 2x20
= 12 + 60 + 40
= 112m^2
B = 2(l x w) + 2(l x h) + 2(w x h)
= 2(2 x 6) + 2(2 x 5) + 2(6 x 5)
= 2x12 + 2x10 + 2x30
= 24 + 20 + 60
= 104m^2

24 pies in 30 minutes. How many pies did each one eat?
steps ?
Answer:
Raymond ate 5
Daniel ate 25
Step-by-step explanation:
x= Raymond
5x= Daniel because he ate 5 times as many as Raymond
x+5x=30
add like terms
6x=30
divide by 6
x=5 Raymond
5*5=25
25=Daniel

7x-y=7
x+2y=6
Answer:
x = 4 / 3, y = 7 / 3
Step-by-step explanation:
We are given the following system of equations;
{ 7x - y = 7, ⇒ Let us multiply the first equation by 2,
x + 2y = 6 }
2 * ( 7x - y = 7 ) ⇒ 14x - 2y = 14 ⇒ Now add the two equations
+ x + 2y = 6 + x + 2y = 6
14x + x = 14 + 6 ⇒ Simplify
15x = 20,
x = 4 / 3 ⇒ Now substitute this value of x into the first equation to solve for the value of y,
7 * ( 4 / 3 ) - y = 7 ⇒ Simplify,
28 / 3 - y = 7,
y = 7 / 3
Solution; x = 4 / 3, y = 7 / 3
Element X decays radioactively with a half life of 14 minutes. If there are 760 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to decay to 11 grams?
Answer:
85.5 minutes
Step-by-step explanation:
The amount of an element that will remain after time t can be expressed as a function of initial amount N0, time t, and half life th as;
Nt = N0 × e^(-λt)
Where;
Decay constant λ = ln(2)/th, substituting into the equation;
Nt = N0 × e^(-ln(2)t/th)
We need to make t the subject of formula;
Nt/N0 = e^(-ln(2)t/th)
ln(Nt/N0) = -ln(2)t/th
t = ln(Nt/N0) ÷ -ln(2)/th
Given;
Initial amount N0 = 760g
Final amount Nt = 11 g
Half life th = 14 minutes
the nearest tenth of a minute, would it take the element to decay to 11 grams can be derived using the formula;
t = ln(Nt/N0) ÷ -ln(2)/th
Substituting the given values;
t = ln(11/760) ÷ -ln(2)/14
t = 85.5 minutes

A flagpole casts a shadow that is 25 feet long. A signpost near the flagpole is 3 feet tall, and it casts a shadow that is 5 feet long. How tall is the flagpole?
Answer:
The ratio of shadow should be kept, then we have: x/25 = 3/5
=> x = 25 x 3/5 = 15
=> The flagpole is tall 15 feet
Hope this helps!
:)
Answer:
15 feet
Step-by-step explanation:
Length : shadow
3 : 5
X : 25
X/25 = 3/5
X = 25 × 3/5
X = 15

Jessica has been tracking the population of a town. The population was 8,230 last year and has been increasing by 1.25 times each year. How can Jessica develop a function to model this?
Answer:
Population at start : 8,230.
The rate of growth: r = 1.25
x - number of the years;
Answer:
B ) f ( x ) = 8,230 * ( 1.25 ) ^x where 1.25 is the rate of growth.
Step-by-step explanation:
Jessica develops a function to model this 8230(1.25)ˣ, where 1.25 is the rate of growth.
What is exponential population growth?In an ideal condition where there is an unlimited supply of food and resources, the population growth will follow an exponential order.
Jessica has been tracking the population of a town.
The population was 8,230 last year and has been increasing by 1.25 times each year.
The population growth function is;
[tex]\rm f(x)=P_0 x^t[/tex]
Substitute all the values in the formula;
[tex]\rm f(x)=P_0 x^t\\\\f(x) = 8230 (1.25)^x[/tex]

Solve this equation for x. Round your answer to
the nearest hundredth.
0 = In(x + 7)
Answer:
x = -6
Step-by-step explanation:
0 = In(x + 7)
x + 7 = e⁰
x + 7 = 1
x = 1 - 7
x = -6
Steps to solve:
0 = In(x + 7)
~Log definition
e^0 = x + 7
~Simplify
1 = x + 7
~Solve for x
1 - 7 = x + 7 - 7
-6 = x
