The simplification of the expression is 48√2
What is simplification?The procedure in mathematics to utilize and analyze the function or expression to make the function or expression uncomplicated or more coherent is called simplifying and the process is called simplification.
We are given the expression as;
2√98-8√32+3√72
Now we have to simplify
2√98-8√32+3√72
2√(49×2) - 8√(4×2) + 3 √(36×2)

Answer:
470 x 1.1 = 517
Step-by-step explanation:
1) Find the missing angle.
31°
949
? + 31° + 94° = 180°
? + 125° = 180°
? = 180° - 125°
? = 55°
Answer: 52°
Step-by-step explanation:
Angles in a triangle always add up to 180°.
So to work out what the missing angle is, you would have to add 34 and 94 together.
34+94=128
Then you would have to take 128 away from 180.
180-128=52°
Hope this helps :)
Find the measure of the indicated angle. Round to the nearest degree.
Answer:
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
5)
Adj = 14
Hyp = 26
∠X
so use
CAH
Cos(X) = 14/26
X = arcCos(14/26)
X = 57.421°
X = 57.4 ° ( rounded to nearest 10th )
6)
∠X
Hyp = 46
Opp = 12
use SOH
Sin(x) = 12/46
X = arcSin(12/46)
X = 15.121°
X = 15.1 ° ( rounded to nearest 10th )
7)
∠X
Adj = 29
Opp = 24
use TOA
Tan(x) = 29 / 24
X = arcTan( 29 /24)
X = 50.389
X = 50.4 ° ( rounded to nearest 10th )
8)
∠X
Adj = 22
Opp = 6
use TOA agian
Tan(x) = 6 / 22
X = arcTan(6/22)
X = 5.194
X = 5.2 ° ( rounded to the nearest 10th )

Explanation:
Use the identities ...
csc(x) = 1/sin(x)
cot(x) = cos(x)/sin(x)
__
[tex]\csc(x)(\sin(x)+\cos(x))=1+\cot(x)\\\\\dfrac{1}{\sin(x)}(\sin(x)+\cos(x))=1+\cot(x)\\\\\dfrac{\sin(x)}{\sin(x)}+\dfrac{\cos(x)}{\sin(x)}=1+\cot(x)\\\\1+\cot(x)=1+\cot(x)[/tex]

if (-1 ,5 ) satisfies the equation 3x + Ky =7 then k =?
Answer:
k = 2
Step-by-step explanation:
3(-1) + k(5) = 7
-3 + 5k = 7
5k = 10
k = 2
The value of K in the equation 3x + Ky =7 is 2.
What is an equation?Two algebraic expressions having same value and symbol '=' in between are called as an equation.
Given:
Equation 3x + Ky =7.
And we have also given that (-1, 5) satisfies the equation.
That means,
(-1, 5) is a solution of the equation.
To find the value of K;
Substitute the value of x = -1 and y = 5
So,
3x + Ky =7,
3(-1) + K(5) =7
-3 + 5K = 7
5K = 10
K = 2
Therefore, the value of K is 2.

if 3x - y = 4,
prove that the roots of x2+(1-k)x+k-3=0 are real for all real values of k
The roots of x^2 + (1 - k).x+k-3 = 0 are real for all real values of k
The equation is given as:
x^2 + (1 - k).x+k-3 = 0
For an equation to have real root, then the following must be true:
[tex]b^2 \ge 4ac[/tex]
In x^2 + (1 - k).x+k-3 = 0, we have:
a = 1
b = 1 - k
c = k - 3
So, we have:
[tex](1 - k)^2 \ge 4 * 1 * (k - 3)[/tex]
Evaluate
[tex]1 - 2k + k^2 \ge 4k - 12[/tex]
Collect like terms
[tex]k^2 - 2k - 4k + 1 + 12 \ge 0[/tex]
[tex]k^2 - 6k + 13 \ge 0[/tex]
Using a graphing calculator, the value of k is all real numbers
Hence, the roots of x^2 + (1 - k).x+k-3 = 0 are real for all real values of k

How many cubes with the side lengths of 1/4 cm does it take to fill the prism?
9514 1404 393
Answer:
224 cubes
Step-by-step explanation:
In terms of 1/4 cm cubes, the dimensions of the prism are ...
(2 cm)/(1/4 cm/cube) = 8 cubes long
(7/4 cm)/(1/4 cm/cube) = 7 cubes wide
(1 cm)/(1/4 cm/cube) = 4 cubes high
The volume in 1/4-cm cubes is ...
V = LWH = (8)(7)(4) = 224 . . . cubes
224 cubes are required to fill the volume.

in the standard form
f(x) = a(x – h)^2 + k
Answer:
y = - ( x + 2 )² + 14
Step-by-step explanation:
f(x) = ax² + bx + c
f(x) = a(x - h)² + k (where (h, k) are coordinates of the vertex.
h = - [tex]\frac{b}{2a}[/tex]
~~~~~~~~~~~~
f(x) = - x² - 4x + 10
a = - 1, b = - 4, c = 10
h = - [tex]\frac{-4}{2(-1)}[/tex] = - 2
k = - ( - 2)² - 4( - 2) + 10 = 14
(h, k) = ( - 2, 14 )
y = - ( x + 2 )² + 14
