What is the simpler form of
(2k²− k+ 3) + (5k²+ 3k +7)?
Answer: 7k^2+2k+10
Step-by-step explanation: To simplify this, you need to combine like terms, which are just the numbers that have the same variables and exponents. Combine 2k^2 and 5k^5 and it is 7k^2 (Just add the coefficient). Then do 3k -k, which is 2k. k just represents 1, so basically, 3-1. Finally, 7 + 3, which is 10. Then, combine the results to form an expression, which is 7k^2+2k+10.

Answer:
744; 1,206
Step-by-step explanation:
Prism 1:
2(19*13) + 5*12 + 2(5*19)
Multiply all the sides.
494 + 60 + 190 = 744
Prism 2:
2(20*9) + 2(18*20) + 9*14
360 + 720 + 126 = 1,206

Given:
[tex](\sin x)^2+(\cos x)^2=1[/tex]
[tex]\cos \theta = \dfrac{4\sqrt{2}}{7}[/tex]
To find:
The value of [tex]\sin \theta[/tex].
Solution:
We have,
[tex]\cos \theta = \dfrac{4\sqrt{2}}{7}[/tex]
Putting this value in the Pythagorean identity, we get
[tex](\sin \theta)^2+(\cos \theta)^2=1[/tex]
[tex](\sin \theta)^2+\left(\dfrac{4\sqrt{2}}{7}\right)^2=1[/tex]
[tex](\sin \theta)^2+\dfrac{16(2)}{49}=1[/tex]
[tex](\sin \theta)^2+\dfrac{32}{49}=1[/tex]
[tex](\sin \theta)^2=1-\dfrac{32}{49}[/tex]
[tex](\sin \theta)^2=\dfrac{49-32}{49}[/tex]
[tex](\sin \theta)^2=\dfrac{17}{49}[/tex]
Taking square root on both sides, we get
[tex]\sin \theta=\pm \sqrt{\dfrac{17}{49}}[/tex]
[tex]\sin \theta=\pm \dfrac{\sqrt{17}}{7}[/tex]
The given value of [tex]\sin \theta[/tex] is positive. So, [tex]\sin \theta= \dfrac{\sqrt{17}}{7}[/tex].
Therefore, the value of value [tex]\sin \theta[/tex] is [tex]\sin \theta= \dfrac{\sqrt{17}}{7}[/tex].

Evaluate the exponential expression. 14^2
Answer:196
Step-by-step explanation:
Answer:
196
Step-by-step explanation:
Exponential expressions are just a way to write powers in short form. The exponent indicates the number of times the base is used as a factor. So in the case of 32, it can be written as 2 × 2 × 2 × 2 × 2=25, where 2 is the “base” and 5 is the “exponent”. We read this expression as “two to the fifth power”.
A health club manager wants to determine whether the members would prefer a new sauna or a new steam room. The club surveys 50 of its 600 members. What is the population of this study? The population is all 50 members of the health club. The population is all 600 and 50 members of the health club. The population is all 600 members of the health club. The population is all 30,000 members of the health club.
Answer:
The population is all 600 members of the health club
Explanation:
50 members were chosen out of all 600 members thereby telling us that the sample of the study/survey is 50 members while the population is all 600 members. A sample represents the population and is collected from the population to make it less tedious to study and make conclusions on the population. For example, given that the population of a study are individuals or objects of common characteristics, 50 members tell the needed story and relays the characteristics and/or definition of the whole population, thereby forming a basis to make a conclusion on the population.

If x = 9 units, y = 3 units, and h = 8 units, find the area of the rhombus shown above using decomposition.
Answer:
[tex]Area = 96[/tex]
Step-by-step explanation:
Given
[tex]x = 9[/tex] [tex]y =3[/tex] [tex]h = 8[/tex]
See attachment for rhombus
Required
Determine the area
From the attached rhombus:
We have
(1) Triangle
[tex]Base = x;\ \ Height = h[/tex]
The area is:
[tex]Area = 0.5 * Base * Height[/tex]
[tex]A_1= 0.5 * x*h[/tex]
[tex]A_1 = 0.5 * 9 *8[/tex]
[tex]A_1 = 36[/tex]
(2) Triangle
[tex]Base = y;\ \ Height = h[/tex]
The area is:
[tex]Area = 0.5 * Base * Height[/tex]
[tex]A_2 =0.5 * y * h[/tex]
[tex]A_2 =0.5 * 3 * 8[/tex]
[tex]A_2 =12[/tex]
(3) Rectangle
[tex]Area = Length * Width[/tex]
[tex]Length =h; Width = x - y[/tex]
because all sides are equal, so the remaining side is x - y
So:
[tex]A_3 = h * (x - y)[/tex]
[tex]A_3 = 8 * (9 - 3)[/tex]
[tex]A_3 = 8 * 6[/tex]
[tex]A_3 = 48[/tex]
So, the area is:
[tex]Area = A_1 + A_2 + A_3[/tex]
[tex]Area = 36 + 12 + 48[/tex]
[tex]Area = 96[/tex]

How do you determine if triangles or any polygons are similar?
For example, all equilateral triangles are similar and all squares are similar. If two polygons are similar, we know the lengths of corresponding sides are proportional. In similar polygons, the ratio of one side of a polygon to the corresponding side of the other is called the scale factor.

we want to find the zeros of this polynomial:
p(x)=(x-1)(x+3)(2x+1)
plot all the zeros (x-intercepts) of the polynomial in the interactive graph.
Answer:
Step-by-step explanation:
To find the zeros of this polynomial, set the polynomial equal to zero, and then set each of the factors equal to zero separately. Solve each equation for x:
x - 1 = 0 yields x = 1. The x-intercept is (1, 0).
x + 3 = 0 yields x = -3. The x-intercept is (-3, 0).
2x + 1 = 0 yields x = -1/2 The x-intercept is (-1/2, 0)
Answer:
(- 3, 0), (- 1/2, 0), (1, 0)
Step-by-step explanation:
p(x)=(x-1)(x+3)(2x+1)
Plug p(x) = 0
Therefore,
(x-1)(x+3)(2x+1) = 0
x - 1 = 0 or x + 3 = 0 or 2x + 1 = 0
x = 1 or x = - 3 or x = - 1/2
Hence, (- 3, 0), (- 1/2, 0), (1, 0) are zeroes of the given polynomial

r = √(A/π) = √(4π/π) = 2 . . . . meters
The circumference is ...
C = 2πr
C = 2π(2 m) = 4π m

a2 = -8 and a5 = -512
Find a10
Answer:
The value of a₁₀ is -1352
Step-by-step explanation:
a₂ = -8
a₅ = -512
Now,
a₂ = -8 can be written as
a + d = -8 ...(1) and
a₅ = -512 can be written as
a + 4d = -512 ...(2)
Now, from equation (2) we get,
a + 4d = - 512
a + d + 3d = - 512
(-8) + 3d = - 512 (.°. a + d = -8)
3d = - 512 + 8
3d = - 504
d = - 504 ÷ 3
d = - 168
Now, for the value of a put the value of d = -168 in equation (1)
a + d = -8
a + (-168) = -8
a - 168 = -8
a = 168 - 8
a = 160
Now, For a₁₀
a₁₀ = a + 9d
a₁₀ = 160 + 9(-168)
a₁₀ = 160 - 1512
a₁₀ = -1352
Thus, The value of a₁₀ is -1352
