Answer:
Area of each triangle is 70 cm²
The total area of the kite is 140 cm²
Step-by-step explanation:
Since the kite is broken into two congruent triangles, therefore:
Total area of the Kite = 2 × area of each triangle
✔️Area of each triangle = ½*base*height
base = 20 m
height = 7 m
Area of each triangle = ½*20*7 = 70 cm²
✔️Total area of the kite = 2(70) = 140 cm²

Answers
Answer:
vertex (-4,-18)
Step-by-step explanation:
f(x)=2(x+1)(x+7)
f(x)=2(x^2+8x+7)
f(x)=2x^2+16x+14
f(x)=2(x^2+8x)+14
f(x)=2(x^2+8x+4^2-4^2)+14
f(x)=2(x^2+8x+4^2)+2(-4^2)+14
f(x)=2(x^2+8x+4^2)+2(-4^2)+14
f(x)=2(x^2+8x+4^2)-18
f(x)=2(x+4)^2-18
vertex form:
f(x)=a(x-h)^2+k
h=-4
k=-18

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)

On Monday in Minneapolis,Minnesota it’s was 0°F outside. On Tuesday it’s was 15 degrees colder. What was the temperature and Tuesday?
Answers
Answer:
-15º F.
Step-by-step explanation:
Given that on Monday in Minneapolis, Minnesota it’s was 0 ° F outside, while on Tuesday it was 15 degrees colder, to determine what was the temperature on Tuesday the following calculation must be performed:
0 - 15 = X
-15 = X
Thus, the temperature on Thursday was -15º Fahrenheit, which is equal to -26.11º Celcius.

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)

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.

3. ¿Cuál es el peso de un (dm) de agua?
Answers
Para los líquidos y los sólidos, la densidad de referencia habitual es la del agua líquida de 1 kg/dm³, esto quiere decir que 1 kg de agua tiene un volumen de 1 dm³, por tanto, podemos determinar el peso de 1 cm³ de agua de la siguiente manera:
En 1 kg de agua ---> Hay 1 dm³ de volumen
Si... 1000 g (Que equivalen a 1 Kg) ---> 1000 cm³ (Que equivalen a 1 dm³)
X ---> 1 cm³
X = 1 cm³ x 1000 g ÷ 1000 cm³
X = 1 g
Por tanto, si el agua es lo suficientemente pura para tener una densidad de 1 Kg/dm³, el peso de 1 cm³ de agua es de 1 gramo.

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
Answers
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)
