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)

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 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)

What is the volume of this cube?
(Answer in decimal form)
Answer:

to find the volume of a cube, you do length x height x width. since a cube has equal sides, you would do 4.2 x 4.2 x 4.2.
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

Gloria, Scott, and Becky are all moving water into a large barrel. Gloria has moved 12 less than 4 times the number of gallons of water as Scott. Becky has moved 16 less than 6 times the number of gallons of water as Scott. If Gloria and Becky have both moved the same number of gallons of water, how many gallons, g, of water has Scott moved?
Which equation below correctly represents the situation above?
A. 4g - 16 = 6g - 12
B. 4g - 6g - 12 = 16
C. 4 × 6 - 12 × 16 = g
D. 4g - 12 = 6g - 16

WHERE DOES THE DECIMAL POINT GO?
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.

A basketball player makes 8 of 22 shots in game 1, 6 of 15 in game 2, and, 10 of 23 in game 3. What percent of the shots did the player make in the three games?
Answer:
50
Step-by-step explanation:
the answer is 50 because you have to add 22+15+23=50 then you add the makes which is 8+7+10=25. Then time both by 2 because percent means per one hundred which means the bottom has to equal 100 so time 50x2=100, So 25x2=50
