Answer:
The Answer is A
Step-by-step explanation:
Trust me I just did the Assignment.
The correct function which has a constant additive rate of change of -1/4 is shown in figure 1.
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable.
Given that;
To find the correct function which has a constant additive rate of change of -1/4.
Now, From figure 1;
Two points are (2,1) and (- 2, 2).
Hence, We get;
Rate of change = (2 - 1) / (- 2 - 2)
= - 1/4
Thus, The correct function which has a constant additive rate of change of -1/4 is shown in figure 1.

In isosceles triangle NTS, NT ≌ TS. If m∠N = 42° and NS = 30 cm, find the length of the altitude of △NTS. (Round answer to the nearest tenth.)
Answers
Answer:
13.5 cm
Step-by-step explanation:
The altitude of the base of the isosceles triangle bisects the vertex angle, <T, and also bisects the base, NS.
Therefore, NS is divide into two, 15 cm each.
This means we now have two right triangles from the isosceles triangle with the following:
Reference angle = 42°
Opposite = altitude = h
Adjacent = 15 cm
To find h, apply trigonometric function, TOA:
Tan 42 = Opp/Adj
Tan 42 = h/15
15 * Tan 42 = h
h = 13.5060607 ≈ 13.5 cm (nearest tenth)

Find the distance between the points (-10,-7) and (2,9).
Answers
Distance formula is:
Sqrt of (x-x1)^2+(y-y1)^2
So define which coordinate is (x,y) and what (x1,y1)
I’m going to define (-10,-7) as (x,y) and (2,9) as (x1,y1)
So plug in your variables!
Sqrt(-10-2)^2+(-7-9)^2
Sqrt-12^2+-16^2
Sqrt144+256
Sqrt400
So sqrt of 400 is 20! :))

The number of people who have heard a rumor is modeled by the logistic function f(x)=2601+23e−0.06x
, where x is the number of days since the rumor began.
Approximately how many days have passed when the rate at which the rumor spreads begins to decrease?
Answers
Answer:
C
Step-by-step explanation:
The number of people who have heard a rumor is modeled by the logistic function:
[tex]\displaystyle f(x)=\frac{260}{1+23e^{-0.06x}}[/tex]
And we want how many days has passed since the rate at which the rumor spread began to decrease.
First, the numerator tells us that the total number of people who will have heard the rumor by the end is 260.
Recall that the point of maximum growth is always half of the maximum capacity.
In this case, that point will be 260/2 = 130.
For a logistic function, the rate of all values to the left of the halfway point is increasing, (i.e. concave up), while the rate of all values to the right is decreasing (i.e. concave down). Therefore, we can solve for x when f(x) = 130:
[tex]\displaystyle 130=\frac{260}{1+23e^{-0.06x}}[/tex]
Cross-multiply:
[tex]130(1+23e^{-0.06x}})=260[/tex]
Distribute:
[tex]130+2990e^{-0.06x}=260[/tex]
Solving for x:
[tex]2990e^{-0.06x}=130[/tex]
Therefore:
[tex]\displaystyle e^{-0.06x}=\frac{130}{2990}=\frac{1}{23}[/tex]
Taking the natural log of both sides:
[tex]\displaystyle -0.06x=\ln\Big(\frac{1}{23}\Big)[/tex]
Therefore:
[tex]\displaystyle x=\frac{\ln(1/23)}{-0.06}\approx52.3[/tex]
After about 52.3 days, the rate at which the rumor started spreading will begin to decrease.

I have a prism with the dimension of 6cm by 12cm by 15 cm. Calculate the volume of the prism, and then give the dimensions of three different prisms that each have 1/3 of thr volume.
Prism 1
Prism 2
Prism 3
Answers
Answer:
Volume = 1080 cubic cmPrism 1 = 2 cm by 5 cm by 36 cmPrism 2 = 3 cm by 10 cm by 12 cmPrism 3 = 4 cm by 6 cm by 15 cm====================================================
Explanation:
To find the volume of the current prism, we multiply length width and height to get 6*12*15 = 1080
Take 1/3 of this to get (1/3)*1080 = 360
To find three different prisms where they have a volume of 360, we just need to think of ways to multiply to 360 using 3 numbers.
Here are some possibilities:
2 * 5 * 36 = 3603 * 10 * 12 = 3604 * 6 * 15 = 3604 * 9 * 10 = 3608 * 9 * 5 = 360There are other possibilities as well, but you only need to pick three from that list. Or you can come up with other combos as well as long as the three numbers multiply to 360.
If we go with the first three rows for prisms 1, 2, and 3 in that exact order, then
prism 1 has dimensions: 2 cm by 5 cm by 36 cmprism 2 has dimensions: 3 cm by 10 cm by 12 cmprism 3 has dimensions: 4 cm by 6 cm by 15 cmIf 6.5 pounds of strawberries cost 20$ what's the unit price?

plz quick solve for f
Answers
Answer: f = 100
Step 1.
We'll need to expand 3(f - 91) by multiplying a term and an expression. The following product distributive property will be used: A(B + C) = AB + AC.
In the example, the expression will consist of 2 terms.
First term: 3 and f.
Second term: 3 and -91
Rewrite 3(f - 91) like this.
3f - 3 × 91
Step 2.
Multiply 3 by 91.
3 × 91 = 273
Hence, the answer is 100.

y = -2x
Step-by-step explanation:
Equation in slope-intercept form is y = mx + b.
m = slope = ∆y/∆x
Using any two points on the line, say (0, 0) and (-20, 40),
Slope (m) = (40 - 0) / (-20 - 0) = 40/-20
Slope (m) = -2
b = y-intercept = the value of y when x = 0.
b = 0
To write the equation of the line, substitute m = -2 and b = 0 into y = mx + b
Thus:
y = -2x + 0
y = -2x
