Answer:
(b) 40°
Step-by-step explanation:
Angle x and the one marked 70° are alternate interior angles, so are congruent. The sum of the two base angles of the isosceles triangle is ...
x° +x° = 70° +70° = 140°
So, the remaining angle 1 in the triangle is ...
180° -140° = 40°
∠1 = 40°

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.
Please need help on this one h as be no clue how to do this
Answers
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

WHERE DOES THE DECIMAL POINT GO?
Answers
Answer:
34.06
Step-by-step explanation:
Answer:
Step-by-step explanation:
This is a very good question to know the answer to. It teaches you the art of estimating. You do that without a calculator.
In this case, just multiply 5 * 6. The answer must be somewhere near 30.
So the decimal goes after the 4.
But your teacher is likely going to want a more formal method. So the formal answer is this: Count the number of decimal places. 5.24 provides 2 decimal places -- the 2 and the 4 are to the right of the decimal.
6.5 adds another one 0.5
Altogether you have 3 decimal places.
Add a decimal after the second 0.
Count 3 places to the left.
You wind up with 34.060 just as you did before.

Graph
X = 2;
Find its intercept(s) and slope.
Answers
Answer:
sorry to tell you this but there is no slope or intercept.
Step-by-step explanation:
Answer:
Only ONE intercept: x = 2 on the x axis
UNDEFINED slope
Step-by-step explanation:
Notice that this equation corresponds to a VERTICAL line, since the value of x is 2 no matter what the value of y is.
Then, we are in the case of a vertical line, where the slope is undefined because it implies a division by zero given that any two points we pick from the line to calculate the slope, will have the SAME x value.
Being a vertical line going through the point x = 2, there is no y-intercept, and the ONLY intercept is with the x-axis at x = 2.
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)

PLEASE ANSWER THE PIC BELOW

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.

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 cmEgad Smogg is saving for a $250 video game system. He has saved 25% of the money so far. How much more does he need to save?
