Find the missing length. Leave your answer as radical in simplest form
Answer:
v = [tex]\frac{7\sqrt{2} }{2}[/tex]
u = [tex]7[/tex]
Step-by-step explanation:
First, the angle on the far left is also 45 degrees.
So, v is equal to [tex]\frac{7\sqrt{2} }{2}[/tex] because this is a 45-45-90 triangle, so the sides opposite the 45-degree angles are congruent.
However, u is the side opposite the 90-degree angle, so it is equal to the other side value, multiplied by [tex]\sqrt{2}[/tex].
So, [tex]\frac{7\sqrt{2}}{2}*\sqrt{2}[/tex] is equal to:
[tex]7[/tex]

What is the image of the point (-1,7)(−1,7) after a rotation of 90^{\circ}90∘counterclockwise about the origin?
Answer:
(- 7, - 1 )
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 90°
a point (x, y ) → (- y, x ) , thus
(- 1, 7 ) → (- 7, - 1 )

find the missing angle measures
Answer:
Step-by-step explanation:
180° ( n - 2 )
n = 6 sides
4( x )° + 2( x - 6 )° = 180° ( 6 - 2 )
4x + 2x - 12 = 720
6x = 732
x = 122
x° = 122 °
( x - 6 )° = 116 °
122° + 116° + 122° + 122° + 116° + 122° = 720°

How to understand the Triangle-sum Theorem?
Answer:
Its Simple All the angles in a triangle adds up to 180°
Step-by-step explanation:
∠A + ∠ B + ∠C = 180° NO matter what. You can also use this in inverse If you have two out of three angles then you can add the two angles you have and subtract the from 180 to get the measurement of the 3rd angle.

[tex]\mathrm{Combine\;fraction}[/tex]
[tex]\frac{2}{3}-\frac{1}{4}:\frac{5}{12}[/tex]

[tex]=1\frac{5}{12}[/tex]
Hence, the answer is 1 5/12
~Lenvy~
1. Convert the 1 and 2/3 from mixed partial fractions to improper fractions to make it a bit simpler to calculate
⇒ [tex]1\frac{2}{3} = \frac{5}{3}[/tex]
2. Now lets the change the base of both fractions into a common denominator and solve
⇒ [tex]\frac{5}{3}-\frac{1}{4} = \frac{5*4}{3*4} -\frac{1*3}{4*3} =\frac{20}{12}-\frac{3}{12} =\frac{20-3}{12} =\frac{17}{12} = 1\frac{5}{12}[/tex]
Answer: [tex]\frac{17}{12}[/tex] or [tex]1\frac{5}{12}[/tex]

A rectangle has a width of 6 units and a length of 2x+8 units. If the area is 108 units squared, what is the value of X?
Answer:
x = 5 units
Step-by-step explanation:
Hello!
We know that the area of a rectangle is the length multiplied by the width.
We can simply create an expression to solve for x.
Solve:
Area = length x width108 = 6(2x + 8)108 = 12x + 4860 = 12xx = 5The value of x is 5 units.
(show ur work btw) Multiply 400 and 45.2 together.
Round to the nearest hundredth when necessary.
Answer:
Answer
18,080
Explantion
400x10=4000x4=16000
400x5=2000
2000+16000=18000
400×.2=80
cause 20% of 400 is 80
so total is 18,080

Answer:
If you mean [tex]\sqrt{ab^{2}[/tex] then the answer is [tex]b\sqrt{a}[/tex]
Step-by-step explanation:
Answer:
ab
Step-by-step explanation:
Original expression:
[tex]\sqrt[]{(ab)^2}[/tex]
Apply the rule [tex](xy)^c=x^c \cdot y^c[/tex]
[tex]\implies \sqrt[]{(ab)^2}=\sqrt[]{a^2 \cdot b^2}[/tex]
Apply the rule [tex]\sqrt{xy}=\sqrt{x} \sqrt{y}[/tex]
[tex]\implies \sqrt[]{a^2 \cdot b^2}=\sqrt{a^2} \sqrt{b^2}[/tex]
Apply the rule [tex]\sqrt{x^2}=x[/tex]
[tex]\implies \sqrt{a^2} \sqrt{b^2}=ab[/tex]

[tex]\sf y \leq \dfrac34x[/tex]
Step-by-step explanation:
Choose 2 points on the line: (0, 0) and (4, 3)
Let [tex]\sf (x_1,y_1)=(0,0)[/tex]Let [tex]\sf (x_2,y_2)=(4,3)[/tex][tex]\sf slope=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{3-0}{4-0}=\dfrac34[/tex]
point-slope form of linear equation: [tex]\sf y-y_1=m(x-x_1)[/tex]
[tex]\implies \sf y-0=\dfrac34(x-0)[/tex]
[tex]\implies \sf y=\dfrac34x[/tex]
Solid line : ≤ or ≥
Dashed line: < or >
Therefore as the line is solid, and the shading is below the line,
[tex]\implies \sf y \leq \dfrac34x[/tex]
Slope:-
