Answers
Use the fact that -1 ≤ sin(x) ≤ 1.
Then
20 ≥ -20 sin(x) ≥ -20 … … … (multiply each side by -20)
-20 ≤ -20 sin(x) ≤ 20 … … … (swap the endpoints)
10x - 20 ≤ 10x - 20 sin(x) ≤ 10x + 20 … … … (add 10x to each side)
and over the interval [7, 8], we have
7 ≤ x ≤ 8
70 ≤ 10x ≤ 80 … … … (multiply each side by 10)
so that the whole integrand is bounded by
70 - 20 ≤ 10x - 20 sin(x) ≤ 80 + 20
50 ≤ 10x - 20 sin(x) ≤ 100
Take m = 50 and M = 100. It follows that
[tex]50(8-7) \le \displaystyle \int_7^8 (10x-20\sin(x)) \, dx \le 100(8-7)[/tex]
which places the value of the integral between 50 and 100.
Katie has $6,500 in a saving account if she earns 6% interest every month how much money does Katie have in your bank account after half a month how much money does Kaite have in her bank account after half a year.
AND IF SOMEONE DARES TO PUT A LINK PLEASE DON'T
Answers
Answer:
bad question sadly she would technechly have 6500 after half a month bc you only apply interest after the minth but im guessing she wants us to half it to make it for half the month so 6500*0.03= $195 in half the month
and half a year would be 6500*.06*6= $2340 after half a year
Luna runs 5,000 m in 35 minutes during a cross-country meet. What was her speed?
A. 0.007 m/min
B. 4,965 N
C. 5,035 N
D. 143 m/min
Answers
Answer:
D
Step-by-step explanation:
to calculate speed ( or v for velocity ) divide the space traveled by the time it took to travel that distance.
v = S/t = 5000m/35min = 143 m/min

Which of the following describes the parabola with the equation y = −x^2 − 3x + 6?
A. The axis of symmetry is x = −1.5 and the vertex is (−1.5, 8.25).
B. The axis of symmetry is x = 0 and the vertex is (0, 6).
C. The axis of symmetry is x = −1 and the vertex is (−1, −3).
D. The axis of symmetry is x = 1.5 and the vertex is (1.5, 12.75).
Answers
Answer:
A. The axis of symmetry is x = −1.5 and the vertex is (−1.5, 8.25).
Step-by-step explanation:
I will solve the problem by applying the perfect square trinomial. In this way we obtain the canonical form. Another way would be to derive the function, but I don't know if you're familiar with it.
First: let us take out the common factor: , since we remember that the canonical form is characterized as follows:
Then, it remains:
Then: the coefficient of the variable We divided it between , And we square it (they will be one positive and one negative). In our case:
Let's accommodate terms to make it easier:
Can be written as :
Now, what is underlined is our perfect square trinomial, let us recall its form:
Applying the same principle we are left:
Applying distributive property we get:
Therefore it will have its vertex in:
The axis of symmetry is a straight line that makes the function to be projected being , for this you need some reference point, for the parabola you need the coordinate in of the vertex.
For which the axis of symmetry is .
I love you so much !
a. The axis of symmetry is x = −1.5 and the vertex is (−1.5, 8.25).
Step-by-step explanation:
The axis of symmetry is x = − b/2a
= -(-3) / 2(-1)
= 3/(-2)
= -1.5
the vertex => x = -1.5
y= -(-1.5)²-3(-1.5)+6 =
-2.25 +4.5+6= 8.25

Step-by-step explanation:
2y = 7(y-2) + 4
→ 2y = 7y - 14 + 4

Mi tío compró un terreno campestre de forma rectangular que mide 3/4 hm de largo y 1/2 de ancho, ¿Cual es su área ?
Answers
Answer:
¿Cómo y por qué? El área de un rectángulo se represa mediante la relación:
Área = largo · ancho
En este caso conocemos:
3/4 hm de largo: l = 3/4
1/2 hm de hm: a = 1/2
La unidad hm, son los hectómetros. Un hectómetro equivale a 100 metros.
Calculamos el área:
A = (3/4 · 1/2) hm²
The area of rectangular piece of land that measures 3/4 m long and 1/2 m wide is 3/8 square meters
What is the Area of Rectangle?The area of rectangle is -
A = L x B
Given is a rectangular piece of land that measures 3/4 m long and 1/2 m wide.
We can calculate the area using the formula -
Area = Length x Width
A = 3/4 x 1/2
A = 3/8 square meters
Hence, the area of rectangular piece of land that measures 3/4 m long and 1/2 m wide is 3/8 square meters

Answer:
x=12
Step-by-step explanation:
<1 and <2 are equal since they are alternate exterior angles for parallel lines
9x+6 = 2(5x-3)
distribute
9x+6 = 10x-6
Subtract 9x from each side
9x+6-9x= 10x-6-9x
6 = x-6
Add 6 from each side
6+6 =x-6+6
12=x
Answer:
See below for answer.
Step-by-step explanation:
m∠1 = m ∠2 If lines are parallel, then alternating exterior angles are =
Therefore
a ║ b Given in the figure
m∠1 = m ∠2
