Please need help on this one h as be no clue how to do this
Answer:
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

A rectangular prism has a length of 714 inches, a width of 612 inches, and a height of 10 inches.
Raj has another prism that has dimensions that are each double the dimensions of the first rectangular prism.
How many times greater is the volume of the larger prism than the volume of the smaller one?
Answer:
8 timesStep-by-step explanation:
The volume of the prism:
V = lwhIf each of the dimensions is doubled, then the volume becomes:
V₁ = 2l*2w*2h = 8lwh = 8VThe larger prism has 8 times greater volume
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?
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.
plz help fast
plz pick a b c or d
Answer:
C (H. x=3)
Step-by-step explanation:
It wants a line where both sides are equal. Since the parabola is opening upward, it has to be an x= equation. That rules out F and J. Next you count out the points to the vertex on the x axis, which seems to be 3. This means that the line is x=3, or H(c)
plz quick solve for f
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.

Step-by-step explanation:
A theater sells t tickets at a price of p dollars each. The theater conducts a survey and predicts that if the price of each ticket is changed by $2, the number of tickets sold will change by 15 tickets. If n is the number of times the theater changes the ticket price by $2, the expression (p+ 2n) (t-15n) can represent the theaters's total revenue, in dollars. In this expression, what does (t-15n) represent?
A. the number of tickets that the theater will sell If the ticket price is increased by $2
B. the number of tickets the theater will sell if the ticket prices increased by $2n
C.the number of tickets the theater will sell if the ticket price is decreased by $15
Answer:
B
Step-by-step explanation:
You have to look at the second term to be sure of the meaning of t - 15n
What the given term says is that the total number of tickets sold (p) will decrease by 15 times the number of increases that there are.
The other term says that the cost of 1 ticket will increase that each ticket will increase by 2 dollars for each change in the ticket prices providing that change is 2 dollars.
C is out of the question. The information talks about 2 dollars per increase which is the first term.
A is not quite correct. It implies there is exactly 1 ticket increase. The crorect answer is the ticket increases can be a number of times (n)

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.)
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)

Answer:
3x -4y = 12
Step-by-step explanation:
The x- and y-intercepts are easily read from the graph as 4 and -3, respectively. Then the intercept form of the equation of the line is ...
x/(x-intercept) +y/(y-intercept) = 1
x/4 +y/(-3) = 1
Multiplying by 12 will clear the fractions and give the standard form:
3x -4y = 12
Solve the equation using the Zero-Product Property. (x - 8)(5x - 6) = 0
