Answer:
The expression 3r - 6 can be written as 3(r - 2)
Step-by-step explanation:
We know that 3r-6=3(r-2) because 3*r is the same as 3r and we know that 3*-2 is -6 hence making them equal. And to check it we know that 3r-6 is equal to 3r-6.
This is a Function?
O True
O False
Answer:
true

From her eye, which stands 1.74 meters above the ground, Sophia measures the angle of elevation to the top of a prominent skyscraper to be 44∘If she is standing at a horizontal distance of 369 meters from the base of the skyscraper, what is the height of the skyscraper? Round your answer to the nearest tenth of a meter if necessary.
The height of the skyscraper for the considered case is evaluated being of 358 meters approx.
What is angle of elevation?You look straight parallel to ground. But when you have to watch something high, then you take your sight up by moving your head up. The angle from horizontal to the point where you stopped your head is called angle of elevation.
How to use right triangles to find the height of the specified sky scrapper?Remember that we assume that building is vertical to the ground. This means, there is 90° formation.
For this case, referring to the figure attached below, we get:
The height of the skyscraper = h = length of ED (which is h - 1.74 meters) + 1.74 meters
Using the tangent ratio for triangle CDE, from the perspective of angle of elevation, we get:
[tex]\tan(44^\circ) = \dfrac{|ED|}{|CD|} = \dfrac{h-1.74}{|AB|} \\0.9656 \approx \dfrac{h-1.74}{369}\\\\h \approx 0.9656 \times 369 + 1.74 \approx 358 \: \rm m[/tex]
(from calculator, we obtained [tex]tan(44^\circ) \approx 0.9656[/tex] )
Thus, the height of the skyscraper for the considered case is evaluated being of 358 meters approx.

Answer:
-49
Step-by-step explanation:
Make sure you understand the difference between
-3² and (-3)²
-3² means square 3, then take its opposite. -3² is the same as -(3²) = -9
(-3)² means square the number -3, which means that (-3)² = (-3) × (-3) = 9
Ok, now we can start. Use the correct order of operations.
-3² + (2 - 6)(10) =
= -9 + (-4)(10)
= -9 + (-40)
= -9 - 40
= -49

Simplify the answer completely and change to a mixed number
Answer:
[tex]4\frac{23}{33}[/tex]
Step-by-step explanation:
[tex]5 \frac{2}{12}[/tex] × [tex]\frac{10}{11}[/tex]
[tex]\frac{62}{12}[/tex] × [tex]\frac{10}{11}[/tex]
[tex]\frac{62*10}{12*11}[/tex]
[tex]\frac{620}{132}[/tex]
Divide both sides by 4
[tex]\frac{155}{33}[/tex]
Now let us write it as a mixed number
[tex]4\frac{23}{33}[/tex]
Hope this helps you :-)
Answer:
Question :[tex] \dashrightarrow{5 \dfrac{2}{12} \times \dfrac{10}{11}}[/tex]
Solution :[tex] \dashrightarrow{5 \dfrac{2}{12} \times \dfrac{10}{11}}[/tex]
Coverting 5-1/2 into improper fraction :
[tex] \dashrightarrow{\dfrac{(5 \times 12) + (2)}{12} \times \dfrac{10}{11}}[/tex]
[tex] \dashrightarrow{\dfrac{(60) + (2)}{12} \times \dfrac{10}{11}}[/tex]
[tex] \dashrightarrow{\dfrac{60 + 2}{12} \times \dfrac{10}{11}}[/tex]
[tex] \dashrightarrow{\dfrac{62}{12} \times \dfrac{10}{11}}[/tex]
Performing multiplication :
[tex] \dashrightarrow{\dfrac{62 \times 10}{12 \times 11}}[/tex]
[tex] \dashrightarrow{\dfrac{620}{132}}[/tex]
Cutting the fraction into simplest form :
[tex] \dashrightarrow{ \cancel{\dfrac{620}{132}}}[/tex]
[tex] \dashrightarrow{ \dfrac{155}{33}}[/tex]
Coverting the improper fraction into mixed fraction :
[tex]{\dashrightarrow{\sf{\underline{\underline{\red{4 \dfrac{22}{33}}}}}}}[/tex]
Hence, the answer is [tex]\bf{4 \dfrac{22}{33}}[/tex].
