[tex]\sum\limits_{k=1}^{5}6\left(4\right)^{k-1}=6\left(4\right)^{1-1}+6\left(4\right)^{2-1}+6\left(4\right)^{3-1}+6\left(4\right)^{4-1}+6\left(4\right)^{5-1}=\\\\\\=6\cdot4^0+6\cdot4^1+6\cdot4^2+6\cdot4^3+6\cdot4^4=6+24+96+384+1536=\\\\=2,046[/tex]
or:
is geometric series: [tex]S_n=\dfrac{a_1(1-q^n)}{1-q}[/tex]
[tex]a_n=a_1\cdot q^{n-1}\quad\implies\quad\begin{cases}a_1=6\\q=4\\n=5\end{cases}[/tex]
so:
[tex]\sum\limits_{k=1}^{5}6\left(4\right)^{k-1}=S_5=\dfrac{6(1-4^5)}{1-4}=\dfrac{6(1-1,024)}{-3}=-2(-1,023)=2,046[/tex]

I think we're probably talking about a right triangle. So just find the adjacent side and the hypotenuse.
Step-by-step explanation:
Once we are considering [tex]x \in \mathbb{R}[/tex], the range of [tex]\text{cos}(x)[/tex] is [tex][1, -1][/tex]. Therefore, [tex]$\frac{42}{41} $[/tex] is not true.
In this exercise, we may have
[tex]$\text{cos}(x)=\frac{x}{r} =\frac{x}{\sqrt{x^2 +y^2} } $[/tex]
Considering the trigonometric functions beyond the unit circle.
Or considering the definition in the right triangle:
[tex]$\text{cos}(x)=\frac{\text{adjacent}}{\text{hypotenuse}} $[/tex]
Why are some right triangles considered special?

Step-by-step explanation:
By the Pythagorean Theorem, you know that:
[tex]C_1B_1=\sqrt{29^2-20^2}=\sqrt{841-400}=\sqrt{441}=21[/tex]
This means that the area of the triangular base is [tex]\dfrac{21\cdot 20}{2}=210[/tex]. Multiplying this by the height of the pyramid and dividing by 3, you get a volume of 3360. Hope this helps!
What is m∠A? Enter your answer in the box.
Answers
Answer:
∠A is 118 degrees
Step-by-step explanation:
every triangle is 180 degrees
(3x+13) + (x-8) +(x) = 180
simplify
5x + 5 = 180
-5 = -5
5x = 175
175 divided by 5 is 35
so x= 35
∠A= 3(35) + 13
3 times 35 is 105
105 + 13 = 118
so ∠A is 118 degrees

17^2 = 289
289 = 289

A sector of a circle whose radius is 4 centimeters, has a central angle of 30 Which of the following. which of following represents the area of this sector in square centimeters?
(1). 12π/5
(2). 8π/15
(3). 4π/3
(4). 6π/5
Answers
Answer:
area of the sector =4π/3 cm²
Step-by-step explanation:
To find the area of the sector, we will follow the steps below;
first write the formula for finding area of a sector
area of a sector = Ф/360 × πr²
where r is the radius
from the question given
Ф= 30 and radius = 4 centimeters
we can proceed to insert the values into he formula above
area of a sector = Ф/360 × πr²
=30/360 ×π×4²
=1/12 ×π×16
=16π /12
=8π/6
=4π/3
area of the sector =4π/3 cm²

Answer:
13 ounces
Step-by-step explanation:
Since the package ended up costing $5.81, we subtract the starting cost of 6 ounces, which is $4.90.
We end up with $0.91. Since each additional ounce is $0.13, we divide 0.91 by 0.13.
This gives us seven, which is the amount of additional ounces. Since Mrs. Washington paid 4.90 for the first six ounces and then there were an additional 7 ounces, we add 6 plus 7.
The answer is 13 ounces. Hope this helps!
